your investment decision. Before making an investment decision, you should read this entire prospectus carefully and you should consider, among other things, the matters set forth under &#147;Risk Factors&#148; and our financial statements and
related notes thereto appearing elsewhere in this prospectus. In this prospectus, except as otherwise indicated, &#147;Delcath,&#148; &#147;Delcath Systems,&#148; &#147;the Company,&#148; &#147;we,&#148; &#147;our,&#148; and &#147;us&#148; refer to
Delcath Systems, Inc., a Delaware corporation and its subsidiaries. &#147;Delcath&#148; is our registered United States trademark. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Company Overview
</B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Delcath Systems, Inc. is an interventional oncology company focused on the treatment of primary and metastatic liver cancers. Our investigational
product, &#147;Melphalan Hydrochloride for Injection for use with the Delcath Hepatic Delivery System&#148; (&#147;Melphalan/HDS&#148;), is designed to administer high-dose chemotherapy to the liver while controlling systemic exposure and associated
side effects. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In the United States, Melphalan/HDS is considered a combination drug and device product, is referred to by its chemical name and delivery
system, Melphalan/HDS, and is regulated as a drug by the Federal Food and Drug Administration (the &#147;FDA&#148;). The FDA has granted us six orphan drug designations, including three orphan designations for the use of the drug melphalan for the
treatment of patients with ocular melanoma liver metastases (&#147;mOM&#148;), hepatocellular carcinoma (&#147;HCC&#148;) and intrahepatic cholangiocarcinoma, a type of primary livery cancer (&#147;ICC&#148;). Melphalan/HDS has not been approved for
sale in the United States. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In Europe, our delivery system, without the drug, is commercially available under the trade name Delcath Hepatic CHEMOSAT<SUP
STYLE="font-size:85%; vertical-align:top">&reg;</SUP> Delivery System for Melphalan (marketed under the name CHEMOSAT and referred to herein as &#147;CHEMOSAT&#148;), where it has been used at major medical centers to treat a wide range of cancers
of the liver. The current version of CHEMOSAT is regulated as a Class&nbsp;IIb medical device and received its CE Mark in 2012. We are in an early phase of commercializing CHEMOSAT in select markets in the European Union (the &#147;EU&#148;) where
the prospect of securing reimbursement coverage for the procedure is strongest. In 2015 national reimbursement coverage for CHEMOSAT procedures was awarded in Germany. In 2016, coverage levels were negotiated between hospitals in Germany and
regional sickness funds. Coverage levels determined via this process are expected to be renegotiated annually. In 2017, Dutch health authorities added CHEMOSAT to their treatment guidelines for patients with ocular melanoma metastatic to the liver,
an important step toward eventual reimbursement in the Dutch market. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Our primary research focus is on mOM and ICC and certain other cancers that are
metastatic to the liver. Currently there are few effective treatment options for certain cancers in the liver. Traditional treatment options include surgery, systemic chemotherapy, liver transplant, radiation therapy, interventional radiology
techniques, and isolated hepatic perfusion. We believe that Melphalan/HDS and CHEMOSAT represent a potentially important advancement in regional therapy for primary liver cancer and certain other cancers metastatic to the liver and are uniquely
positioned to treat the entire liver either as a standalone therapy or as a complement to other therapies. We believe the disease states we are investigating represent a multi-billion dollar global market opportunity and a clear unmet medical need.
</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Our clinical development program for Melphalan/HDS is comprised of the FOCUS Clinical Trial for Patients with Hepatic Dominant Ocular Melanoma (the
&#147;FOCUS Trial&#148;), a global registration clinical trial that is investigating objective response rate in mOM, and the ALIGN Trial, a global Phase 3 clinical trial for ICC (the &#147;ALIGN Trial&#148;). Our product also includes a registry for
CHEMOSAT commercial cases performed in Europe and sponsorship of select Investigator Initiated Trials. </P>

Liver&#151;A Significant Unmet Need </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Cancers of the liver remain a major unmet medical need globally. According to the American Cancer Society&#146;s
<I>Cancer Facts</I><I></I><I>&nbsp;&amp; Figures 2018</I> report, cancer is the second leading cause of death in the United States, with an estimated 609,640 deaths and 1.7&nbsp;million new cases expected to be diagnosed in 2018. Cancer is one of
the leading causes of death worldwide, accounting for approximately 9.6&nbsp;million deaths and 18.1&nbsp;million new cases in 2018 according to GLOBOCAN, the database of the International Association of Cancer Registries. The financial burden of
cancer is enormous for patients, their families and society. The Agency for Healthcare Quality and Research estimates that the direct medical costs (total of all healthcare expenditures) for cancer in the United States in 2015 was
$80.2&nbsp;billion. The liver is often the life-limiting organ for cancer patients and one of the leading causes of cancer death. Patient prognosis is generally poor once cancer has spread to the liver. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Liver Cancers&#151;Incidence and Mortality </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">There are two
types of liver cancers: primary liver cancer and metastatic liver disease. Primary liver cancer (hepatocellular carcinoma or HCC, including intrahepatic bile duct cancers or ICC) originates in the liver or biliary tissue and is particularly
prevalent in populations where the primary risk factors for the disease, such as <FONT STYLE="white-space:nowrap">hepatitis-B,</FONT> <FONT STYLE="white-space:nowrap">hepatitis-C,</FONT> high levels of alcohol consumption, aflatoxin, cigarette
smoking and exposure to industrial pollutants, are present. Metastatic liver disease, also called liver metastasis, or secondary liver cancer, is characterized by microscopic cancer cell clusters that detach from the primary site of disease and
travel via the blood stream and lymphatic system into the liver, where they grow into new tumors. These metastases often continue to grow even after the primary cancer in another part of the body has been removed. Given the vital biological
functions of the liver, including processing nutrients from food and filtering toxins from the blood, it is not uncommon for metastases to settle in the liver. In many cases patients die not as a result of their primary cancer, but from the tumors
that metastasize to their liver. In the United States, metastatic liver disease is more prevalent than primary liver cancer. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Ocular Melanoma </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Ocular melanoma is one of the cancer histologies with a high likelihood of metastasizing to the liver. Based on third party research that we commissioned in
2018, we estimate that up to 4,700 cases of ocular melanoma are diagnosed in the United States and Europe annually, and that approximately 55% of these patients will develop metastatic disease. Of metastatic cases of ocular melanoma, we estimate
that approximately 90% of patients will develop liver involvement. Once ocular melanoma has spread to the liver, current evidence suggests median overall survival for these patients is generally six to eight months. Currently, there is no standard
of care for patients with ocular melanoma liver metastases. Based on the research conducted in 2018, we estimate that approximately 2,000 patients with ocular melanoma liver metastases in the United States and Europe may be eligible for treatment
with the Melphalan/HDS. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Hepatobiliary cancers include HCC and ICC, and are among the most prevalent and lethal forms of cancer. According to GLOBOCAN, an estimated 78,500 new cases of
hepatobiliary cancers are diagnosed in the United States and Europe annually. According to the American Cancer Society, approximately 42,030 new cases of these cancers are expected to be diagnosed in the United States in 2019, leading to
approximately 31,780 deaths. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">ICC is the second most common primary liver tumor and accounts for 3% of all gastrointestinal cancers and 15% of
hepatobiliary cases diagnosed in the United States and Europe annually. We believe that 90% of ICC patients are not candidates for surgical resection, and that approximately <FONT STYLE="white-space:nowrap">20-30%</FONT> of these may be candidates
for certain focal interventions. According to third party research that we commissioned in 2018 we estimate that approximately 11,000 ICC patients in the United States and Europe annually could be candidates for treatment with Melphalan/HDS, which
we believe represents a significant market opportunity. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">According to the American Cancer Society, the overall five-year survival rate for hepatobiliary
cancers in the United States is approximately 18%. For patients diagnosed with a localized stage of disease, the American Cancer Society estimates <FONT STYLE="white-space:nowrap">5-year</FONT> survival at 31%. The American Cancer Society estimates
that <FONT STYLE="white-space:nowrap">5-year</FONT> survival for all cancers is 68%. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>About CHEMOSAT and Melphalan/HDS </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Our product administers concentrated regional chemotherapy to the liver. This &#147;whole organ&#148; therapy is performed by isolating the circulatory system
of the liver, infusing the liver with a chemotherapeutic agent, and then filtering the blood prior to returning it to the patient. During the procedure, known as percutaneous hepatic perfusion,
PHP<SUP STYLE="font-size:85%; vertical-align:top">&reg;</SUP>, (&#147;PHP therapy&#148;), three catheters are placed percutaneously through standard interventional radiology techniques. The catheters temporarily isolate the liver from the
body&#146;s circulatory system, allow administration of the chemotherapeutic agent melphalan hydrochloride directly to the liver, and collect blood exiting the liver for filtration by our proprietary filters. The filters absorb chemotherapeutic
agent in the blood, thereby reducing systemic exposure to the drug and related toxic side effects, before the filtered blood is returned to the patient&#146;s circulatory system. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">PHP therapy is performed in an interventional radiology suite in approximately two to three hours. Patients remain in an intensive care or step-down unit
overnight for observation following the procedure. Treatment with CHEMOSAT and Melphalan/HDS is repeatable, and a new disposable system is used for each treatment. Patients treated in clinical settings are permitted up to six treatments. In
commercial treatment settings, patients have received up to eight treatments. In the United States, melphalan hydrochloride for injection will be included as part of the product offering, if approved. In Europe, the system is sold separately and
used in conjunction with melphalan hydrochloride commercially available from a third party. In our clinical trials, melphalan hydrochloride for injection is provided to both European and United States clinical trial sites. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">An investment in our securities involve a high degree of risk. You should carefully consider the risks described below, together with the financial and other
information contained in this annual report, before you decide to purchase our securities. If any of the following risks actually occurs, our business, financial condition, results of operations, cash flows and prospects could be materially and
adversely affected. If any of these risks actually occur, our business, financial condition and results of operations would suffer. In that event, the trading price of our Common Stock and the market value of the securities offered hereby could
decline, and you may lose all or part of your investment. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B><I>Our independent registered public accounting firm has expressed
substantial doubt about our ability to continue as a going concern. </I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Our independent registered public accounting firm issued a report dated
June&nbsp;14, 2019 in connection with the audit of our financial statements as of December&nbsp;31, 2018, which included an explanatory paragraph describing the existence of conditions that raise substantial doubt about our ability to continue as a
going concern. In addition, the notes to our financial statements for the year ended December&nbsp;31, 2018, included in our Annual Report on Form <FONT STYLE="white-space:nowrap">10-K</FONT> filed with the Commission on June 14, 2019, contain a
disclosure describing the existence of conditions that raise substantial doubt about our ability to continue as a going concern.&nbsp;Our ability to continue as a&nbsp;going concern&nbsp;is dependent upon our ability to obtain substantial additional
funding in connection with our continuing operations. Adequate additional financing may not be available to us on acceptable terms, or at all. If the Company is unable to raise additional capital and/or enter into strategic alliances when needed or
on attractive terms, Delcath would be forced to delay, reduce or eliminate its research and development programs or any commercialization efforts. The Company&#146;s consolidated financial statements do not include any adjustments that might result
from the outcome of this uncertainty. If the Company is not able to continue as a going concern, it is likely that holders of its Common Stock will lose all of their investment. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B><I>Drug development is an inherently uncertain process with a high risk of failure at every stage of development. Delcath received a
complete response letter from the FDA declining to approve our existing New Drug Application, or NDA, in its current form. </I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Preclinical testing and
clinical trials are long, expensive and highly uncertain processes and failure can unexpectedly occur at any stage of clinical development. Drug development is very risky, and it takes several years to complete clinical trials. The start or end of a
clinical trial is often delayed or halted due to changing regulatory requirements, manufacturing challenges, required clinical trial administrative actions, slower than anticipated patient enrollment, changing standards of care, availability or
prevalence of use of a comparator treatment or required prior therapy, clinical outcomes including insufficient efficacy, safety concerns, or our own financial constraints. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In response to our NDA, which the Company submitted to FDA in August 2012 seeking approval for use of our Melphalan/HDS Kit for the treatment of patients with
ocular melanoma of the liver, in September 2013, the FDA denied approval of the NDA in its current form and issued a complete response letter (CRL). A CRL is issued by the FDA when the review of an NDA is completed, and deficiencies remain that
preclude approval of the NDA in its current form. The deficiencies in the CRL included, but were not limited to, a statement that Delcath must perform additional &#147;well-controlled randomized trial(s) to establish the safety and efficacy of
Melphalan/HDS Kit using overall survival as the primary efficacy outcome measure&#148; and which &#147;demonstrates that the clinical benefits of Melphalan/HDS Kit outweigh its risks.&#148; The FDA also required that the additional clinical trial(s)
be conducted using the product the Company intends to market. Prior to conducting additional clinical trials, Delcath must satisfy certain other requirements of the CRL, including, but not limited to, product quality testing and human factors
information. </P>

<Center><DIV STYLE="width:8.5in" align="left">
 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Delcath has initiated a pivotal Phase 3 trial in ocular melanoma metastases. Delcath had a SPA agreement
with FDA for this study, which was initially designed as a randomized trial with a primary endpoint of overall survival. We subsequently amended the protocol so that the trial is a <FONT STYLE="white-space:nowrap">non-randomized,</FONT> <FONT
STYLE="white-space:nowrap">single-arm</FONT> study with a primary endpoint of objective response rate. Although the changes to the protocol invalidated the SPA agreement, FDA stated that it would not object to Delcath conducting a study outside of a
SPA agreement. However, Delcath will need to justify how the results of the study support a favorable risk-benefit assessment, particularly whether the response rate is sufficient to overcome the toxicity of Melphalan/HDS. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In addition, Delcath conducts and participates in numerous clinical trials with a variety of study designs, patient populations and trial endpoints to support
additional indications for Melphalan/HDS and HDS with other drug therapies. In 2014, Delcath initiated a Phase 2 clinical trial with Melphalan/HDS for hepatocellular carcinoma (&#147;HCC&#148;) in both the United States and Europe. In 2015, the
Phase 2 clinical trial for HCC was expanded to include a cohort of patients with intrahepatic cholangiocarcinoma, a type of primary livery cancer (&#147;ICC&#148;). The trial for this cohort was conducted at the same centers participating in the
Phase 2 HCC trial. Unfavorable or inconsistent clinical data from clinical trials, including the Phase 2 clinical trial for HCC, the market&#146;s perception of these clinical data or FDA&#146;s perception of this clinical data, may adversely impact
our ability to obtain approval, and our financial condition. Additionally, even if the results of our Phase 2 clinical trial for HCC and ICC are positive, there is a substantial risk that it will fail to have positive results in Phase 3 clinical
trials with regard to efficacy, safety or other clinical outcomes and may never obtain regulatory approval. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B><I>The Company does not
expect to generate significant revenue for the foreseeable future. </I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Delcath&#146;s entire focus has been on developing, commercializing, and
obtaining regulatory authorizations and approvals of CHEMOSAT<SUP STYLE="font-size:85%; vertical-align:top">&reg;</SUP> and Melphalan/HDS and currently has only developed this system for the treatment of cancers in the liver. If CHEMOSAT and
Melphalan/HDS for the treatment of cancers in the liver fail as commercial products, the Company has no other products to sell. In addition, since CHEMOSAT currently is approved for commercialization solely in the European Economic Area (the
&#147;EEA&#148;) and limited other jurisdictions, if medac, our third-party distributor, is unsuccessful in commercializing the product in the EEA and/or if Melphalan/HDS is not approved in the United States and elsewhere, the Company will have no
means of generating revenue. In September 2013, the FDA issued a CRL with respect to the Company&#146;s NDA for Melphalan/HDS. A CRL is issued by the FDA when the review of a file is completed and questions remain that preclude approval of the NDA
in its then current form. Accordingly, Delcath does not expect to realize any revenues from product sales in the United States in the next several years, if at all. As a result, our revenue sources are, and will remain, extremely limited until the
Company&#146;s product candidates are approved by the FDA or other additional foreign regulatory agencies and successfully marketed. CHEMOSAT and Melphalan/HDS may not be successful in clinical trials, approved by the FDA or other additional foreign
regulatory agency or marketed at any time in the foreseeable future or at all. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B><I>Continuing losses may exhaust our capital resources.
</I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">As of June&nbsp;30, 2019, the Company had $352,000 in cash and cash equivalents. Delcath has had minimal revenue to date, and has a substantial
accumulated deficit, recurring operating losses and negative cash flow. For the years ended December&nbsp;31, 2018 and 2017, the Company incurred net losses of approximately $19.2&nbsp;million and $45.1&nbsp;million, respectively and expects to
continue to incur losses in 2019. Subsequent to June&nbsp;30, 2019 the Company closed on a $20.0&nbsp;million private placement in July 2019 and a $9.5 private placement in August 2019 which management believes will fund the Company through the
first half of 2020. To date, the Company has funded operations through a combination of private placements and public offerings of its securities, including convertible notes. If Delcath continues to incur losses, the Company may exhaust its capital
resources, and as a result may be unable to complete its clinical trials, engage in product development and the regulatory approval process and commercialization of CHEMOSAT and Melphalan/HDS or any other versions of these products. If Delcath is
unable to raise capital or generate sufficient revenue, it may not be able to pay its debts when they become due and may have to seek protection from the bankruptcy courts or enter into a receivership. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Company will require additional financing to complete its clinical trial program or seek other approvals, to conduct future development and clinical trials
and to further commercialize its product in the EEA and any other markets where the Company may receive approval for its products. In addition, Delcath is obligated to make payments under long-term research and development obligations and lease
agreements. If financing is unavailable to make the required payments under these agreements, the Company could be subject to legal liability and its ability to complete product development projects or clinical trials could be impaired. The Company
does not know if additional financing will be available when needed at all or on acceptable terms. If unable to obtain additional financing as needed, the Company may not be able to further commercialize CHEMOSAT and Melphalan/HDS, obtain regulatory

device product. If marketed individually, each component would therefore be subject to different regulatory pathways and reviewed by different centers within the FDA. A combination product, however, is assigned to a center that will have primary

and any material changes to the approved product, such as manufacturing changes, product improvements or revised labeling, may require further regulatory review. Additionally, the Company is subject to ongoing audits by its European Notified Body,

for potentially costly post-marketing testing, including Phase IV clinical trials, and surveillance to monitor the safety and efficacy of the product candidate. In addition, if the FDA approves a product candidate, the manufacturing processes,
labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for the product will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and
other post-marketing information and reports, registration, as well as continued compliance with current good manufacturing practice (&#147;cGMPs&#148;), good clinical practices (&#147;GCPs&#148;), and good laboratory practices, which are

cause the Company to cease the development of Melphalan/HDS for other indications. If Delcath is unable to develop Melphalan/HDS for other indications, the future growth of our business could be negatively impacted. In addition, Delcath has limited
clinical data relating to the effectiveness of Melphalan/HDS in certain types of cancer. Such limited data could slow the adoption of CHEMOSAT and Melphalan/HDS and significantly reduce Delcath&#146;s ability to commercialize CHEMOSAT and
Melphalan/HDS. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B><I>The Company relies on third parties to conduct certain elements of the clinical trials for CHEMOSAT and

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Company designs the clinical trials for Melphalan/HDS, but relies on academic institutions, corporate partners, contract research organizations and other
third parties to assist in managing, monitoring and otherwise carrying out these trials. Delcath relies heavily on these parties for the execution of its clinical studies and control only certain aspects of their activities. Accordingly, the Company
may have less control over the timing and other aspects of these clinical trials than if Delcath conducted them entirely on its own. The Company relies upon third parties to conduct monitoring and data collection of its ongoing and future clinical
trials, including its Phase 3 ocular melanoma trial and pivotal ICC trial. Although Delcath relies on these third parties to manage the data from these clinical trials, Delcath is responsible for confirming that each of its clinical trials is
conducted in accordance with its general investigational plan and protocol. Moreover, the FDA and foreign regulatory agencies require Delcath to comply with GCPs for conducting, recording and reporting the results of clinical trials to assure that
the data and results are credible and accurate and that the trial participants are adequately protected. The FDA enforces these GCP regulations through periodic inspections of trial sponsors, principal investigators and trial sites. The
Company&#146;s reliance on third parties does not relieve it of these responsibilities and requirements and if Delcath or the third parties upon whom the Company relies for its clinical trials fail to comply with the applicable GCPs, the data
generated in its clinical trials may be deemed unreliable and the FDA or other foreign regulatory agencies may require Delcath to perform additional trials before approving our marketing application. The Company cannot assure you that, upon
inspection, the FDA will determine that any of its clinical trials comply or complied with GCPs. In addition, Delcath&#146;s clinical trials must be conducted with product that complies with the FDA&#146;s cGMP requirements. The Company&#146;s
failure to comply with these regulations may require it to repeat clinical trials, which would delay the regulatory approval process, and may result in a failure to obtain regulatory approval for Melphalan/HDS if these requirements are not met. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B><I>Purchasers of CHEMOSAT in the EEA may not receive third-party reimbursement or such
reimbursement may be inadequate. Without adequate reimbursement, Delcath may not be able to successfully commercialize CHEMOSAT in the EEA. </I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The
Company has obtained the right to affix the CE Mark for CHEMOSAT, and under the medac License, medac intends to seek third-party or government reimbursement within those countries in the EEA where it expects to market and sell CHEMOSAT. In Germany,
the Company had received a ZE diagnostic-related group code (&#147;ZE Code&#148;), which, beginning in 2016, permits hospitals in Germany to obtain reimbursement for CHEMOSAT procedures. Negotiations on the amount of reimbursement to be received
under the ZE Code were concluded in 2016 and the procedure was reimbursed under the ZE Code in 2017. Reimbursement negotiations under the ZE system are conducted annually. Consequently, reimbursement obtained may not be for the full amount sought.
In countries where medac is able to obtain reimbursement, local policy could limit the Company&#146;s ability to obtain adequate and consistent reimbursement and limit other sales opportunities in those countries. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In other countries, until medac obtains government reimbursement, it will rely on private payors or
<FONT STYLE="white-space:nowrap">local&nbsp;pre-approved&nbsp;funds</FONT> where available. There are also no assurances that third-party payors or government health agencies of Member States of the EEA will reimburse use of CHEMOSAT in the long
term or at all. Further, each country has its own protocols regarding reimbursement, so successfully obtaining third party or government health agency reimbursement in one country does not necessarily translate to similar reimbursement in other EEA
countries. Physicians, hospitals and other health care providers may be reluctant to purchase CHEMOSAT if they do not receive substantial reimbursement for the cost of using the product from third-party payors or government entities. The lack of
adequate reimbursement may significantly limit sales opportunities in the EEA. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B><I>The success of our products may be harmed if the
government, private health insurers and other third-party payers do not provide sufficient coverage or reimbursement. </I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Company&#146;s ability
to commercialize CHEMOSAT under the medac License and Melphalan/HDS successfully will depend in part on the extent to which reimbursement for the costs of such products and related treatments will be available from government health administration
authorities, private health insurers and other third-party payors. Melphalan/HDS is currently not approved by the FDA. Medicare, Medicaid, private health insurance plans and their foreign equivalents will not reimburse the use of Melphalan/HDS since
the product is currently not approved outside the EEA. Delcath will seek reimbursement by third-party payors of the cost of Melphalan/HDS after its use is approved, but there are no assurances that adequate third-party coverage will be available for
Delcath to establish and maintain price levels sufficient for the Company to realize an appropriate return on its investment in developing new therapies. Government, private health insurers and other third-party payors are increasingly attempting to
contain healthcare costs by limiting both coverage and the level of reimbursement for new therapeutic products approved for marketing. Accordingly, even if coverage and reimbursement are provided by government, private health insurers and
third-party payors for uses of our products, market acceptance of these products would be adversely affected if the reimbursement available proves to be unprofitable for healthcare providers. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Implementation of healthcare reforms in the United States and in significant overseas markets may limit the ability to commercialize CHEMOSAT and
Melphalan/HDS and the demand for CHEMOSAT and Melphalan/HDS. Healthcare providers may respond to such cost-containment pressures by choosing lower cost products or other therapies. In March 2010, the Patient Protection and Affordable Care Act and
Health Care and Education Reconciliation Act of 2010 (&#147;ACA&#148;) was enacted into law in the United States, which included a number of provisions aimed at improving quality and decreasing costs. The Trump administration has taken executive
actions and has eliminated the individual shared responsibility penalty portion of ACA. A court decision finding that the ACA is unconstitutional is on appeal. </P>

medical community and third-party payers as clinically useful, cost effective and safe. Acceptance by the medical community may depend on the extent to which leaders in the scientific and medical communities publish scientific papers in reputable
academic journals. If testing and clinical practice do not confirm the safety and efficacy of CHEMOSAT and Melphalan/HDS or even if further testing and clinical practice produce positive results but the medical community does not view these
favorably, and CHEMOSAT and Melphalan/HDS as effective and desirable, our efforts to market CHEMOSAT and Melphalan/HDS may fail, which would cause us to cease operation. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The cost of healthcare has risen significantly over the past decade and numerous initiatives and reforms initiated by legislators, regulators and third-party
payors to curb these costs have resulted in a consolidation trend in the medical device industry. Group purchasing organizations, independent delivery networks and large single accounts in the United States and foreign markets may result in a
consolidation of purchasing decisions for potential healthcare provider customers. The Company expects that market demand, government regulation, third-party reimbursement policies and societal pressures will continue to change the worldwide
healthcare industry, resulting in further business consolidations and alliances which may exert further downward pressure on the price of CHEMOSAT and Melphalan/HDS and adversely impact our business, financial condition and results of operations.
</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Further, third-party payors may deny reimbursement if they determine that CHEMOSAT and/or Melphalan/HDS is not used in accordance with established payor
protocols regarding cost effective treatment methods or is used outside its approved indication or for forms of cancer or with drugs not specifically approved by the FDA or other foreign regulatory bodies in the future. Without reimbursement,
physicians, hospitals and other health care providers will be less likely to purchase CHEMOSAT and/or Melphalan/HDS, thereby harming our results of operations. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">There are three third-party manufacturers of melphalan in certain countries of the EEA of which the Company is aware. If any of these manufacturers fails to <FONT
STYLE="white-space:nowrap">provide&nbsp;end-users&nbsp;with</FONT> adequate supplies of melphalan or fails to comply with the requirements of regulatory authorities, Delcath may be unable to successfully commercialize our product in the EEA. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Under the current regulatory scheme in the EEA, CHEMOSAT is approved for marketing as a device only, and doctors will separately obtain melphalan for use with
CHEMOSAT. Although melphalan has been approved in the EEA for over a decade, the Company is aware that there are currently three approved manufacturers of melphalan in certain countries of the EEA. As a result, there may not be sufficient supply of
melphalan for use with CHEMOSAT, and any adverse change in a manufacturer&#146;s commercial operations or regulatory approval status may seriously impair Delcath&#146;s sales opportunities in the EEA. Additionally, melphalan is not available in
certain foreign countries outside the EEA where Delcath may seek to market CHEMOSAT. If supply of melphalan remains limited or unavailable, the Company will be unable to commercialize CHEMOSAT in these markets, thereby limiting future sales
opportunities. </P>

States. The Company intends to use the melphalan supplied by Synerx and Bioniche to conduct its global Phase 3 trials for ocular melanoma liver metastases and ICC. Delcath may pursue agreements with additional contract manufacturers to produce
melphalan and other chemotherapeutic agents that it will use in the future for its clinical trial program and the commercialization of CHEMOSAT and Melphalan/HDS, as well as for labeling and finishing services. The Company may not be able to enter
into such arrangements on acceptable terms or at all. Every manufacturer is subject to inspection by FDA and must meet all cGMP regulatory requirements. To manufacture melphalan or other chemotherapeutic agents on its own, Delcath would first have
to develop a manufacturing facility that complies with FDA requirements and regulations for the production of melphalan and each other chemotherapeutic agent the Company chooses to manufacture for its system. Developing these resources would be an
expensive and lengthy process and would have a material adverse effect on the Company&#146;s revenues and profitability. If Delcath is unable to obtain sufficient melphalan and labeling services on acceptable terms, if it should encounter delays or

unable to obtain an adequate supply of the necessary components or negotiate acceptable terms, it may not be able to manufacture CHEMOSAT and Melphalan/HDS in commercial quantities or in a cost-effective manner, and commercialization of CHEMOSAT and
Melphalan/HDS in the United States, the EEA and elsewhere may be delayed. In addition, certain components are available from only a limited number of sources. Components of CHEMOSAT and Melphalan/HDS are currently manufactured for Delcath in small
quantities and may require significantly greater quantities to further commercialize the product. The Company may not be able to find alternate sources of comparable components. If Delcath is unable to obtain adequate supplies of components from
existing suppliers or needs to switch to an alternate supplier and obtain FDA or other regulatory agency approval of that supplier, commercialization of CHEMOSAT and Melphalan/HDS may be delayed. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B><I>Even if the Company receives FDA or other foreign regulatory approvals, Delcath may be unsuccessful in commercializing CHEMOSAT and
Melphalan/HDS in markets outside the EEA, because of inadequate infrastructure or an ineffective commercialization strategy. </I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Outside the EEA, even
if the Company obtains regulatory approval from the FDA or other foreign regulatory agencies, its ability to commercialize CHEMOSAT and Melphalan/HDS may be limited due to Delcath&#146;s inexperience in developing a sales, marketing and distribution
infrastructure. If the Company is unable to develop this infrastructure in the United States or elsewhere or to collaborate with an alliance partner to market its products in the United States or foreign countries, particularly in Asia,
Delcath&#146;s efforts to commercialize CHEMOSAT and Melphalan/HDS or any other product outside of the EEA may be less successful. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Even if the Company is
successful in commercializing CHEMOSAT and Melphalan/HDS in the EEA, Delcath may not be successful in the United States and other foreign countries. Each country requires a different commercialization strategy, so the Company&#146;s EEA marketing
strategy may not translate to other markets. Without a successful commercialization strategy tailored for each market, Delcath&#146;s efforts to promote and market CHEMOSAT in each of its target markets may fail in any or all of those markets. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B><I>The Company&#146;s plan to use collaborative arrangements with third parties to help finance and to market and sell CHEMOSAT and
Melphalan/HDS may not be successful. </I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Company may be unable to enter into collaborative agreements without additional clinical data or unable
to continue a collaborative agreement as a result of unsuccessful future clinical trials. Additionally, Delcath may face competition in its search for alliances. As a result, the Company may not be able to enter into any additional alliances on
acceptable terms, if at all. The Company&#146;s collaborative relationships may never result in the successful development or commercialization of CHEMOSAT and Melphalan/HDS or any other product. The success of any collaboration will depend upon
Delcath&#146;s ability to perform its obligations under any agreements as well as factors beyond its control, such as the commitment of its collaborators and the timely performance of their obligations. The terms of any such collaboration may permit
Delcath&#146;s collaborators to abandon the alliance </P>

intellectual property rights to the same extent as laws in the United States. Consequently, we may not be able to prevent third parties from copying our inventions in all countries outside the United States. Competitors may use our technologies in
jurisdictions where we have not obtained patent protection that covers the commercial products to develop their own competing products that are the same or substantially the same as our commercial product and, further, may export otherwise
infringing products to territories where we have patent protection, but judicial systems do not adequately enforce patents to cause infringing activities to be ceased. </P>

foreign jurisdictions where we do have patent rights, proceedings to enforce such rights could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or
interpreted narrowly, and our patent applications at risk of not issuing, and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be
commercially meaningful. Thus, we may not be able to stop a competitor from marketing and selling in foreign countries products that are the same as or similar to our product and technologies. </P>

use, litigation may be necessary. Our intellectual property has not been tested in litigation. There is no assurance that any of our issued patents will be upheld if later challenged or will provide significant protection or commercial advantage. A
court may declare our patents invalid or unenforceable, may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question, or may interpret the claims of our patents
narrowly, thereby substantially narrowing the scope of patent protection they afford. Because of the length of time and expense associated with bringing new medical drugs and devices to the market, the healthcare industry has traditionally placed
considerable emphasis on patent and trade secret protection for significant new technologies. Other parties may challenge patents, patent claims or patent applications licensed or issued to us or may design around technologies we have patented,
licensed or developed. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In addition, third parties may initiate legal or administrative proceedings against us to challenge the validity or scope of our
intellectual property rights, or may allege an ownership right in our patents, as a result of their past employment or consultancy with us. Many of our current and potential competitors have the ability to dedicate substantially greater resources to
defend their intellectual property rights than we can. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon or misappropriating our intellectual property. Competing products may also be sold in other
countries in which our patent coverage might not exist or be as strong. If we lose a foreign patent lawsuit, alleging our infringement of a competitor&#146;s patents, we could be prevented from marketing our product in one or more foreign countries.
</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The medical device industry has been characterized by frequent and extensive intellectual property litigation. Our competitors or other patent holders
may assert that our products and the methods employed in our products are covered by their patents. Although we have performed a search for third-party patents and believe we have adequate defenses available if faced with any allegations that we
infringe these third-party patents, it is possible that CHEMOSAT and Melphalan/HDS could be found to infringe these patents. It is also possible that our competitors or potential competitors may have patents, or have applied for, will apply for, or
will obtain patents that will prevent, limit or interfere with our ability to make, have made, use, sell, import or export our product. If our products or methods are found to infringe, we could be prevented from manufacturing or marketing our

damages, treble damages, and attorneys&#146; fees, and could prohibit us from using technologies essential to our product, any of which would have a material adverse effect on our business, results of operations, and financial condition. If relevant
patents are upheld as valid and enforceable and we are found to infringe, we could be prevented from selling our product unless we can obtain licenses to use technology or ideas covered by such patents. We do not know whether any necessary licenses
would be available to us on satisfactory terms, if at all. If we cannot obtain these licenses, we could be forced to design around those patents at additional cost or abandon the product altogether. Furthermore, because of the substantial amount of
discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. There could also be public announcements of the
results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could cause the price of our Common Stock to decline. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">If others have filed patent applications with respect to inventions for which we already have patents issued to us or have patent applications pending, we may
be forced to participate in interference or derivation proceedings declared by the USPTO to determine priority of invention, which could also be costly and could divert our attention from our business. If the USPTO declares an interference and
determines that our patent or application is not entitled to a priority date earlier than that of the other patent application, our ability to maintain or obtain those patent rights will be curtailed. Similarly, if the USPTO declares a derivation
proceeding and determines that the invention covered by our patent application was derived from another, we will not be able to obtain patent coverage of that invention. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Because of the extensive time required for development, testing and regulatory review of a potential product, it is possible that, before CHEMOSAT and
Melphalan/HDS or any other Delcath product can be commercialized, any related patent may expire or remain in force for only a short period following commercialization, thereby reducing any advantages of the patent. Not all of our United States
patent rights have corresponding patent rights effective in Europe or other foreign jurisdictions. Similar considerations apply in any other country where we are prosecuting patent applications, have been issued patents, or have decided not to
pursue patent protection relating to our technology. The laws of foreign countries may not protect our intellectual property rights to the same extent as do laws of the United States. </P>

surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents. The Leahy-Smith Act includes a number of significant changes to United States patent law. These include provisions that affect the way
patent applications are prosecuted, redefine prior art, may affect patent litigation, and switch the United States patent system from a <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">&#147;first-to-invent&#148;</FONT></FONT>

entitled to the patent on an invention regardless of whether another inventor had made the invention earlier. The USPTO recently developed new regulations and procedures to govern administration of the Leahy-Smith Act, and many of the substantive
changes to patent law associated with the Leahy-Smith Act, in particular, the <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">first-inventor-to-file</FONT></FONT> provisions, only became effective on March&nbsp;16, 2013. As case
law continues to develop in response to this legislation, it is not yet clear what the full impact of the Leahy-Smith Act will have on the operation of our business. However, the Leahy-Smith Act and its implementation could increase the
uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In addition, patent
reform legislation may pass in the future that could lead to additional uncertainties and increased costs surrounding the prosecution, enforcement, and defense of our patents and applications. Furthermore, the United States Supreme Court and the
United States Court of Appeals for the Federal Circuit have made, and will likely continue to make, changes in how the patent laws of the United States are interpreted. Similarly, foreign courts have made, and will likely continue to make, changes
in how the patent laws in their respective jurisdictions are interpreted. We cannot predict future changes in the interpretation of patent laws or changes to patent laws that might be enacted into law by United States and foreign legislative bodies.
Those changes may materially affect our patents or patent applications and our ability to obtain and enforce or defend additional patent protection in the future. </P>

challenged. Third parties may oppose our trademark applications, or otherwise challenge our use of our trademarks. In addition, third parties may use marks that are confusingly similar to our own, which could result in confusion among our customers,
thereby weakening the strength of our brand or allowing such third parties to capitalize on our goodwill. In such an event, or if our trademarks are successfully challenged, we could be forced to rebrand our product, which could result in loss of
brand recognition and could require us to devote resources to advertising and marketing new brands. Our competitors may infringe our trademarks and we may not have adequate resources to enforce our trademark rights in the face of any such

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B><I>The Company may be the subject of product liability claims or product recalls, and it may be unable to maintain insurance adequate to
cover potential liabilities. </I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Company&#146;s business exposes Delcath to potential liability risks that may arise from clinical trials and the
testing, manufacture, marketing, sale and use of CHEMOSAT and Melphalan/HDS. In addition, because CHEMOSAT and Melphalan/HDS are intended for use in patients with cancer, there is an increased risk of death among the patients treated with
Delcath&#146;s system which may increase the risk of product liability lawsuits related to clinical trials or commercial sales. The Company may be subject to claims against it even if the injury is due to the actions of others. For example, if the
medical personnel that use Delcath&#146;s system on patients are not properly trained or are negligent in the use of the system, the patient may be injured, which may subject Delcath to claims. Were such a claim asserted, the Company would likely
incur substantial legal and related expenses even if Delcath prevails on the merits. Claims for damages, whether or not successful, could cause delays in clinical trials and result in the loss of physician endorsement, adverse publicity and/or limit
the Company&#146;s ability to market and sell the system, resulting in loss of revenue. In addition, it may be necessary for Delcath to recall products that do not meet approved specifications, which would also result in adverse publicity, as well
as resulting in costs connected to the recall and loss of revenue. A successful products liability claim or product recall would have a material adverse effect on Delcath&#146;s business, financial condition and results of operations. The Company
currently carries product liability and clinical trial insurance coverage, but it may be insufficient to cover one or more large claims. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Risks Related

expects it to continue to be, volatile. The price at which Delcath&#146;s Common Stock trades depends upon a number of factors, including historical and anticipated operating results, the Company&#146;s financial situation, announcements of
technological innovations or new products by Delcath or its competitors, its ability or inability to raise the additional capital needed and the terms on which it may be raised, and general market and economic conditions. Some of these factors are
beyond the Company&#146;s control. Broad market fluctuations may lower the market price of Delcath&#146;s Common Stock and affect the volume of trading, regardless of the Company&#146;s financial condition, results of operations, business or

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Securities Enforcement and Penny Stock Reform Act of 1990 requires additional disclosure relating to the market for penny stocks in connection with trades
in any stock defined as a penny stock. The Commission has adopted regulations that generally define a penny stock to be any equity security that has a market price of less than $5.00 per share, subject to certain exceptions. Such exceptions include
any equity security listed on NASDAQ and any equity security issued by an issuer that has (i)&nbsp;net tangible assets of at least $2,000,000, if such issuer has been in continuous operation for three years; (ii)&nbsp;net tangible assets of at least
$5,000,000, if such issuer has been in continuous operation for less than three years; or (iii)&nbsp;average annual revenue of at least $6,000,000, if such issuer has been in continuous operation for less than three years. Unless an exception is
available, the regulations require the delivery, prior to any transaction involving a penny stock, of a disclosure schedule explaining the penny stock market and the risks associated therewith. These additional requirements may discourage
broker-dealers from effecting transactions in securities that are classified as penny stocks, which could severely limit the market price and liquidity of such securities and the ability of purchasers to sell such securities in the secondary market.

future prospects and other factors deemed relevant by the Company&#146;s board of directors. Delcath&#146;s ability to pay cash dividends in the future could be limited or prohibited by the terms of financing agreements that it may enter into or by
the terms of any preferred stock that may be authorized and issued. The Company does not expect to pay dividends in the foreseeable future. As a result, holders of Delcath&#146;s Common Stock must rely on stock appreciation for any return on their

<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Board Leadership Structure.&nbsp;Roger G. Stoll, Ph.D. was appointed Executive Chairman effective September 2014 and designated Chairman in connection with
the appointment of Dr.&nbsp;Simpson as director effective October&nbsp;2015. Dr.&nbsp;Stoll has been a member of the Board of Directors since 2008. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">It is
our policy to separate the Chairman and Chief Executive Officer roles. We believe this structure is appropriate for Delcath because it allows our President and CEO to concentrate on
<FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">Delcath&#146;s&nbsp;day-to-day&nbsp;operations,</FONT></FONT> while providing for effective oversight by the Chairman, who is involved in strategic and key matters, such as business
strategy, major transactions and the broader business of Delcath. For a company like Delcath that is focused on the development, approval and commercialization of a specialized product in an extremely technical, highly regulated and intensely
competitive industry, we believe our President and CEO is in the best position to lead our management team, in part because of the depth of her experience in conducting clinical trials in oncology, and to respond to the current pressures and needs
of a company in the stage of growth and development of Delcath, with assistance from our Chairman who also focuses the Board&#146;s attention on the broader issues of corporate business strategy and corporate governance. We believe that splitting
the roles between Chairman, on the one hand, and President and CEO, on the other hand, minimizes any potential conflicts that may result from combining the roles of CEO, President and Chairman, and maximizes the effectiveness of our management and
governance processes to the benefit of our stockholders. Our President and CEO and Chairman regularly consult with each other as part of this structure. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Board&#146;s Role in Risk Oversight.&nbsp;The Board as a whole is responsible for risk oversight, with reviews in certain areas being conducted by the
relevant Board committees. Each of the Board&#146;s committees oversees the management of risks associated with their respective areas of responsibility. In performing this oversight function, the committees are assisted by management which provides
visibility about the identification, assessment and monitoring of potential risks and management&#146;s strategy to mitigate such risks. Key members of management responsible for a particular area report directly to the Board committee charged with
oversight of the associated function and, if the circumstances require, the whole Board. The Board committees review various risk exposures with the full Board and otherwise keep the full Board abreast of the committees&#146; risk oversight
activities throughout the year, as necessary or appropriate. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Risk Assessment of Compensation Programs.&nbsp;Our Compensation and Stock Option Committee
annually evaluates whether our compensation programs encourage excessive risk-taking by employees at the expense of long-term Company value. Based upon its assessment, including a review of the overall annual award limitations and individual annual
limitations in the Company&#146;s stock incentive plans and the Compensation Committee&#146;s role in the consideration and approval of certain awards, the Compensation and Stock Option Committee does not believe that our compensation programs
encourage excessive or inappropriate risk-taking, motivate imprudent risk-taking or create risks that are reasonably likely to have a material adverse effect on the Company. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Board Committees.&nbsp;Our Board has three standing committees: an Audit Committee, a Compensation and Stock Option Committee and a Nominating and Corporate
Governance Committee. No individual director is the chairman of more than one committee. Mr.&nbsp;Sylvester joined the board in July 2019 and has not been appointed to any committee yet. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>Audit Committee</I>. The Audit Committee provides assistance to the Board in fulfilling its oversight responsibilities with respect to the Company&#146;s

 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Our primary research focus is on ocular melanoma liver metastases (&#147;mOM&#148;) and intrahepatic
cholangiocarcinoma (&#147;ICC&#148;), a type of primary liver cancer, and certain other cancers that are metastatic to the liver. We believe the disease states we are investigating represent a multi-billion dollar global market opportunity and a
clear unmet medical need. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Our clinical development program (&#147;CDP&#148;) for Melphalan/HDS is comprised of The FOCUS Clinical Trial for Patients with
Hepatic Dominant Ocular Melanoma (the &#147;FOCUS Trial&#148;), a global registration clinical trial that is investigating objective response rate in mOM, and the ALIGN Trial, a global Phase 3 clinical trial for ICC (the &#147;ALIGN Trial&#148;).
Our CDP also includes a registry for CHEMOSAT commercial cases performed in Europe and sponsorship of select investigator-initiated trials (&#147;IITs&#148;). </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The direction and focus of our CDP for CHEMOSAT and Melphalan/HDS is informed by; prior clinical development conducted between 2004 and 2010, commercial
experience with CHEMOSAT cases performed on patients in Europe, and prior regulatory engagement with the FDA. Experience gained from this research and development, early European commercial cases and United States regulatory opinion has led to the
implementation of several safety improvements to our product and the associated medical procedure. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In the United States, Melphalan/HDS is considered a
combination drug and device product and is regulated as a drug by the FDA. The FDA has granted us six orphan drug designations, including three orphan designations for the use of the drug melphalan for the treatment of patients with mOM,
hepatocellular carcinoma and ICC. Melphalan/HDS has not been approved for sale in the United States. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In Europe, the current version of our CHEMOSAT
product is regulated as a Class&nbsp;IIb medical device and received its CE Mark in 2012. We are in an early phase of commercializing the CHEMOSAT system in select markets in the European Union (EU) where the prospect of securing reimbursement
coverage for the procedure is strongest. In 2015 national reimbursement coverage for CHEMOSAT procedures was awarded in Germany. In 2016, coverage levels were negotiated between hospitals in Germany and regional sickness funds. Coverage levels
determined via this process are expected to be renegotiated annually. In 2017, Dutch health authorities added CHEMOSAT to their treatment guidelines for patients with ocular melanoma metastatic to the liver, an important step toward eventual
reimbursement in the Dutch market. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Currently there are few effective treatment options for certain cancers in the liver. Traditional treatment options
include surgery, systemic chemotherapy, liver transplant, radiation therapy, interventional radiology techniques, and isolated hepatic perfusion. We believe that CHEMOSAT and Melphalan/HDS represent a potentially important advancement in regional
therapy for primary liver cancer and certain other cancers metastatic to the liver and are uniquely positioned to treat the entire liver either as a standalone therapy or as a complement to other therapies. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Cancers of the liver remain a major unmet medical need globally. According to the American Cancer Society&#146;s (&#147;ACS&#148;)<I> Cancer
Facts</I><I></I><I>&nbsp;&amp; Figures 2018</I> report, cancer is the second leading cause of death in the United States, with an estimated 609,640 deaths and 1.7&nbsp;million new cases expected to be diagnosed in 2018. Cancer is one of the leading
causes of death worldwide, accounting for approximately 9.6&nbsp;million deaths and 18.1&nbsp;million new cases in 2018 according to GLOBOCAN, the database of the International Association of Cancer Registries. The financial burden of cancer is
enormous for patients, their families and society. The Agency for Healthcare Quality and Research estimates that the direct medical costs (total of all healthcare expenditures) for cancer in the United States in 2015 was $80.2&nbsp;billion. The
liver is often the life-limiting organ for cancer patients and one of the leading causes of cancer death. Patient prognosis is generally poor once cancer has spread to the liver. </P>

prevalent in populations where the primary risk factors for the disease, such as <FONT STYLE="white-space:nowrap">hepatitis-B,</FONT> <FONT STYLE="white-space:nowrap">hepatitis-C,</FONT> high
levels of alcohol consumption, aflatoxin, cigarette smoking and exposure to industrial pollutants, are present. Metastatic liver disease, also called liver metastasis, or secondary liver cancer, is characterized by microscopic cancer cell clusters
that detach from the primary site of disease and travel via the blood stream and lymphatic system into the liver, where they grow into new tumors. These metastases often continue to grow even after the primary cancer in another part of the body has
been removed. Given the vital biological functions of the liver, including processing nutrients from food and filtering toxins from the blood, it is not uncommon for metastases to settle in the liver. In many cases patients die not as a result of
their primary cancer, but from the tumors that metastasize to their liver. In the United States, metastatic liver disease is more prevalent than primary liver cancer. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Ocular Melanoma </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Ocular melanoma is one of the cancer
histologies with a high likelihood of metastasizing to the liver. Based on third party research that we commissioned in 2018, we estimate that up to 4,700 cases of ocular melanoma are diagnosed in the United States and Europe annually, and that
approximately 55% of these patients will develop metastatic disease. Of metastatic cases of ocular melanoma, we estimate that approximately 90% of patients will develop liver involvement. Once ocular melanoma has spread to the liver, current
evidence suggests median overall survival for these patients is generally six to eight months. Currently there is no standard of care for patients with ocular melanoma liver metastases. Based on the research conducted in 2018, we estimate that
approximately 2,000 patients with ocular melanoma liver metastases in the United States and Europe may be eligible for treatment with the Melphalan/HDS. </P>

include HCC and ICC and are among the most prevalent and lethal forms of cancer. According to GLOBOCAN, an estimated 78,500 new cases of hepatobiliary cancers are diagnosed in the United States and Europe annually. According to the ACS,
approximately 42,030 new cases of these cancers are expected to be diagnosed in the United States in 2019, leading to approximately 31,780 deaths. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">ICC is
the second most common primary liver tumor and accounts for 3% of all gastrointestinal cancers and 15% of hepatobiliary cases diagnosed in the United States and Europe annually. We believe that 90% of ICC patients are not candidates for surgical
resection, and that approximately <FONT STYLE="white-space:nowrap">20-30%</FONT> of these may be candidates for certain focal interventions. According to third party research that we commissioned in 2018 we estimate that approximately 9,300 ICC
patients in the United States and Europe annually could be candidates for treatment with Melphalan/HDS, which we believe represents a significant market opportunity. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">According to the ACS, the overall five-year survival rate for hepatobiliary cancers in the United States is approximately 18%. For patients diagnosed with a
localized stage of disease, the ACS estimates <FONT STYLE="white-space:nowrap">5-year</FONT> survival at 31%. The ACS estimates that <FONT STYLE="white-space:nowrap">5-year</FONT> survival for all cancers is 68%. </P>

concentrated regional chemotherapy to the liver. This &#147;whole organ&#148; therapy is performed by isolating the circulatory system of the liver, infusing the liver with a chemotherapeutic agent, and then filtering the blood prior to returning it
to the patient. During the procedure, known as percutaneous hepatic perfusion, PHP<SUP STYLE="font-size:85%; vertical-align:top"> </SUP><SUP STYLE="font-size:85%; vertical-align:top">&reg;</SUP>, (&#147;PHP therapy&#148;), three catheters are placed
percutaneously through standard interventional radiology techniques. The catheters temporarily isolate the liver from the body&#146;s circulatory system, allow administration of the chemotherapeutic agent melphalan hydrochloride directly to the
liver, and collect blood exiting the liver for filtration by our proprietary filters. The filters absorb chemotherapeutic agent in the blood, thereby reducing systemic exposure to the drug and related toxic side effects, before the filtered blood is
returned to the patient&#146;s circulatory system. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">PHP therapy is performed in an interventional radiology suite in approximately two to three hours. Patients
remain in an intensive care or step-down unit overnight for observation following the procedure. Treatment with CHEMOSAT and Melphalan/HDS is repeatable, and a new disposable system is used for each treatment. Patients treated in clinical settings
are permitted up to six treatments. In commercial treatment settings, patients have received up to eight treatments. In the United States, melphalan hydrochloride for injection will be included as part of the system, if approved. In Europe, the
system is sold separately and used in conjunction with melphalan hydrochloride commercially available from a third party. In our clinical trials, melphalan hydrochloride for injection is provided to both European and United States clinical trial

introduced the Generation Two version of the CHEMOSAT system, which offered improved hemofiltration and other device component product enhancements. Reports from treating physicians in both Europe and the United States using the Generation Two
CHEMOSAT and Melphalan/HDS, in a commercial setting, have suggested that these product improvements and procedure refinements have improved the safety profile. Since 2017, physicians in Europe and the United States have presented and published the
results of research that signaled an improved safety profile, as well as efficacy in multiple tumor types. Collection of adequate safety data on all aspects of the procedure is a major focus of the clinical trials in our current CDP. </P>

accompanied by a significant user fee, which may be waived in certain circumstances. Once the submission has been accepted for filing, the FDA&#146;s goal is to review applications within ten
months of submission or, if the application relates to an unmet medical need in a serious or life-threatening indication, six months from submission. The review process is often significantly extended by FDA requests for additional information or
clarification. The FDA may refer the application to an advisory committee for review, evaluation and recommendation as to whether the application should be approved. For new oncology products, the FDA will often solicit an opinion from an ODAC, a
panel of expert authorities knowledgeable in the fields of general oncology, pediatric oncology, hematologic oncology, immunologic oncology, biostatistics, and other related professions. The ODAC panel reviews and evaluates data concerning the
safety and effectiveness of marketed and investigational human drug products for use in the treatment of cancer, and makes appropriate recommendations to the Commissioner of Food and Drugs. The FDA is not bound by the recommendation of an advisory
committee. The FDA may deny approval of an NDA by issuing a Complete Response Letter (CRL) if the applicable regulatory criteria are not satisfied. A CRL may require additional clinical data and/or an additional pivotal Phase 3 clinical trial(s),
and/or other significant, expensive and time-consuming requirements related to clinical trials, preclinical studies or manufacturing. Data from clinical trials are not always conclusive and the FDA may interpret data differently than we or our
collaborators interpret data. Approval may be contingent on a Risk Evaluation and Mitigation Strategy (REMS) that limits the labeling, distribution or promotion of a drug product. Once issued, the FDA may withdraw product approval if ongoing
regulatory requirements are not met or if safety problems occur after the product reaches the market. In addition, the FDA may require testing, including Phase IV clinical trials, and surveillance programs to monitor the safety effects of approved
products which have been commercialized, and the FDA has the power to prevent or limit further marketing of a product based on the results of these post-marketing programs or other information. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">There are three primary regulatory pathways for a New Drug Application under Section&nbsp;505 of the FFDCA: Section&nbsp;505 (b)(1), Section&nbsp;505 (b)(2)
and Section&nbsp;505(j).&nbsp;A Section&nbsp;505 (b)(1) application is used for approval of a new drug (for clinical use) whose active ingredients have not been previously approved. A Section&nbsp;505 (b)(2) application is used for a new drug that
relies on data not developed by the applicant. Section&nbsp;505(b)(2) of the FFDCA was enacted as part of the Drug Price Competition and Patent Term Restoration Act of 1984, also known as the Hatch-Waxman Act. This statutory provision permits the
approval of an NDA where at least some of the information required for approval comes from studies not conducted by or for the applicant and for which the applicant has not obtained a right of reference. The Hatch-Waxman Act permits the applicant to
rely in part upon the FDA&#146;s findings of safety and effectiveness for previously approved products. Section&nbsp;505(j) application, also known as an abbreviated NDA, is used for a generic version of a drug that has already been approved. </P>

the United States, may designate drugs for relatively small patient populations as orphan drugs. Pursuant to the Orphan Drug Act, the FDA grants orphan drug designation to drugs intended to treat a rare disease or condition, which is generally a
disease or condition that affects fewer than 200,000 individuals in the United States. The orphan designation is granted for a combination of a drug entity and an indication and therefore it can be granted for an existing drug with a new (orphan)
indication. Applications are made to the Office of Orphan Products Development at the FDA and a decision or request for more information is rendered in 60 days. NDAs for designated orphan drugs are exempt from user fees, obtain additional clinical
protocol assistance, are eligible for tax credits up to 50% of research and development costs, and are granted a seven-year period of exclusivity upon approval. The FDA cannot approve the same drug for the same condition during this period of
exclusivity, except in certain circumstances where a new product demonstrates superiority to the original treatment. Exclusivity begins on the date that the marketing application is approved by the FDA for the designated orphan drug, and an orphan
designation does not limit the use of that drug in other applications outside the approved designation in either a commercial or investigational setting. </P>

their subcontractors are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with ongoing regulatory
requirements, including cGMPs, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. Following such inspections, the FDA may issue notices on Form 483 and Untitled Letters or Warning Letters that

Form 483 Notice, if issued at the conclusion of an FDA inspection, can list conditions the FDA investigators believe may have violated cGMP or other FDA regulations or guidelines. In addition to
Form 483 Notices and Untitled Letters or Warning Letters, failure to comply with the statutory and regulatory requirements can subject a manufacturer to possible legal or regulatory action, such as suspension of manufacturing, seizure of product,
injunctive action or possible civil penalties. We cannot be certain that we or our present or future third-party manufacturers or suppliers will be able to comply with the cGMP regulations and other ongoing FDA regulatory requirements. If we or our
present or future third-party manufacturers or suppliers are not able to comply with these requirements, the FDA may require us to recall our products from distribution or withdraw any potential approvals of an NDA for that product. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The FDA closely regulates the post-approval marketing and promotion of drugs, including standards and regulations for <FONT STYLE="white-space:nowrap"><FONT
STYLE="white-space:nowrap">direct-to-consumer</FONT></FONT> advertising, dissemination of <FONT STYLE="white-space:nowrap">off-label</FONT> information, industry-sponsored scientific and educational activities and promotional activities involving
the Internet. Drugs may be marketed only for the approved indications and in accordance with the provisions of the approved label. Further, if there are any modifications to the drug, including changes in indications, labeling, or manufacturing
processes or facilities, we may be required to submit and obtain FDA approval of a new or supplemental NDA, which may require us to develop additional data or conduct additional preclinical studies and clinical trials. Failure to comply with these
requirements can result in adverse publicity, Warning Letters, corrective advertising and potential civil and criminal penalties. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Physicians may
prescribe legally available products for uses that are not described in the product&#146;s labeling and that differ from those tested by us and approved by the FDA. Such <FONT STYLE="white-space:nowrap">off-label</FONT> uses are common across
medical specialties, in particular in oncology. Physicians may believe that such <FONT STYLE="white-space:nowrap">off-label</FONT> uses are the best treatment for many patients in varied circumstances. The FDA does not regulate the behavior of
physicians in their choice of treatments. The FDA does, however, impose stringent restrictions on manufacturers&#146; communications regarding <FONT STYLE="white-space:nowrap">off-label</FONT> use. </P>

system is subject to regulation as a medical device. The EEA is composed of the 27 Member States of the EU plus Norway, Iceland and Liechtenstein. Under the EU Medical Devices Directive (Directive No 93/42/ECC of 14&nbsp;June 1993, as last amended),
drug delivery products such as the CHEMOSAT system is governed by the EU laws on pharmaceutical products only if they are (i)&nbsp;placed on the market in such a way that the device and the pharmaceutical product form a single integral unit which is
intended exclusively for use in the given combination, and (ii)&nbsp;the product is not reusable. In such cases, the drug delivery product is governed by the EU Code on Medicinal Products for Human Use (Directive 2001/83/EC, as last amended), while
the essential requirements of the EU Medical Devices Directive apply to the safety and performance-related device features of the product. Because we do not intend to place the CHEMOSAT system on the EEA market as a single integral unit with
melphalan, the product is governed solely by the EU Medical Devices Directive, while the separately marketed drug is governed by the EU Code relating to Medicinal Products for Human Use and other EU legislation applicable to drugs for human use.
</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Before we may commercialize a medical device in the EEA, we must comply with the essential requirements of the EU Medical Devices Directive. Compliance
with these requirements entitles a manufacturer to affix a CE conformity mark, without which the products cannot be commercialized in the EEA. To demonstrate compliance with the essential requirements and obtain the right to affix the CE conformity
mark, medical device manufacturers must undergo a conformity assessment procedure, which varies according to the type of medical device and its classification. In April 2011, we obtained authorization to affix a CE Mark for the Generation One
CHEMOSAT system and began European commercialization with this version of the CHEMOSAT system in early 2012. In April 2012, the Company obtained authorization to affix a CE Mark for the Generation Two CHEMOSAT system, and since this time all
procedures in Europe have been performed with this version of the system. </P>

IIb, or III, depending on the risks and characteristics of the medical device. For certain types of low risk medical devices (i.e., Class&nbsp;I devices which are <FONT STYLE="white-space:nowrap">non-sterile</FONT> and do not have a measuring
function), the manufacturer may issue an EC Declaration of Conformity based on a self-assessment of the conformity of its products with the essential requirements of the EU Medical Devices Directives. Other devices are subject to a conformity
assessment procedure requiring the intervention of a Notified Body, which is an organization designated by a Member State of the EEA to conduct conformity assessments. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">CHEMOSAT is regulated as a Class&nbsp;IIb medical device. As a Class&nbsp;IIb medical device, the Notified Body is not required to carry out an examination of
the product&#146;s design dossier as part of its conformity assessment prior to commercialization. The Company must continue to comply with the essential requirements of the EU Medical Devices Directive (Directive 93/42 EC) and is subject to a
conformity assessment procedure requiring the intervention of a Notified Body. The conformity assessment procedure for Class&nbsp;IIb medical devices requires the manufacturer to apply for the assessment of its quality system for the design,
manufacture and inspection of its medical devices by a Notified Body. The Notified Body will audit the system to determine whether it conforms to the provisions of the Medical Devices Directive. If the Notified Body&#146;s assessment is favorable,
it will issue a Full Quality Assurance Certificate, which enables the manufacturer to draw a Declaration of Conformity and affix the CE mark to the medical devices covered by the assessment. Thereafter, the Notified Body will carry out periodic
audits to ensure that the approved quality system is applied by the manufacturer. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">A manufacturer without a registered place of business in a Member State
of the EU which places a medical device on the market under its own name must designate an Authorized Representative established in the European Union who can act before, and be addressed by, the Competent Authorities on the manufacturer&#146;s
behalf with regard to the manufacturer&#146;s obligations under the EU Medical Devices Directive. We appointed such a representative prior to establishing our infrastructure in the EEA. With the Delcath Systems Ltd. infrastructure now firmly in
place, the Authorized Representative responsibilities have been formally transferred internally and there is no longer a need for a third-party representative. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In the EEA, we must also comply with the Medical Device Vigilance System, which is designed to improve the protection of health and safety of patients, users
and others by reducing the likelihood of recurrence of incidents related to the use of a medical device. Under this system, incidents are defined as any malfunction or deterioration in the characteristics and/or performance of a device, as well as
any inadequacy in the labeling or the instructions for use which, directly or indirectly, might lead to or might have led to the death of a patient, or user or of other persons or to a serious deterioration in their state of health. When a medical
device is suspected to be a contributory cause of an incident, its manufacturer or authorized representative in the EU must report it to the Competent Authority of the Member State where the incident occurred. Incidents are generally investigated by
the manufacturer. The manufacturer&#146;s investigation is monitored by the Competent Authority, which may intervene, or initiate an independent investigation if considered appropriate. An investigation may conclude in the adoption of a Field Safety
Corrective Action (FSCA). An FSCA is an action taken by a manufacturer to reduce a risk of death or serious deterioration in the state of health associated with the use of a medical device that is already placed on the market. An FSCA may include
device recall, modification exchange and destruction. FSCAs must be notified by the manufacturer or its authorized representative to its customers and/or the end users of the medical device via a Field Safety Notice. </P>

designed to enable us to satisfy the various international quality system regulations including those of the FDA with respect to products sold in the United States and those established by the International Standards Organization (ISO) with respect
to products sold in the EEA. The Company is&nbsp;required to maintain ISO 13485 certification for medical devices to be sold in the EEA, which requires, among other items, an implemented quality system that applies to component quality, supplier
control, product design and manufacturing operations. On February&nbsp;17, 2011, we announced that we had achieved ISO 13485 certification for our Queensbury manufacturing facility. On December&nbsp;28, 2011, we announced that we had achieved ISO

System for Melphalan (&#147;CHEMOSAT&#148;), where it has been used at major medical centers to treat a wide range of cancers of the liver. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">Our primary research focus is on ocular melanoma liver metastases (&#147;mOM&#148;) and intrahepatic cholangiocarcinoma (&#147;ICC&#148;), a
type of primary liver cancer, and certain other cancers that are metastatic to the liver. We believe the disease states we are investigating represent a multi-billion dollar global market opportunity and a clear unmet medical need. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">The direction and focus of our CDP for CHEMOSAT and Melphalan/HDS is informed by; prior
clinical development conducted between 2004 and 2010, commercial experience with CHEMOSAT cases performed on patients in Europe, and prior regulatory engagement with the FDA. Experience gained from this research and development, early European
commercial cases and United States regulatory opinion has led to the implementation of several safety improvements to our product and the associated medical procedure. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">In the United States, Melphalan/HDS is considered a combination drug and device product and is regulated as a drug by the FDA. The FDA has
granted us six orphan drug designations, including three orphan designations for the use of the drug melphalan for the treatment of patients with mOM, hepatocellular carcinoma and ICC. Melphalan/HDS has not been approved for sale in the United
States. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">In Europe, the current version of our CHEMOSAT product is regulated as a Class&nbsp;IIb medical device and received its CE Mark in
2012. We are in an early phase of commercializing the CHEMOSAT system in select markets in the European Union (EU) where the prospect of securing reimbursement coverage for the procedure is strongest. In 2015 national reimbursement coverage for
CHEMOSAT procedures was awarded in Germany. In 2016, coverage levels were negotiated between hospitals in Germany and regional sickness funds. Coverage levels determined via this process are expected to be renegotiated annually. In 2017, Dutch
health authorities added CHEMOSAT to their treatment guidelines for patients with ocular melanoma metastatic to the liver, an important step toward eventual reimbursement in the Dutch market. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">Currently there are few effective treatment options for certain cancers in the liver. Traditional treatment options include surgery, systemic
chemotherapy, liver transplant, radiation therapy, interventional radiology techniques, and isolated hepatic perfusion. We believe that CHEMOSAT and Melphalan/HDS represent a potentially important advancement in regional therapy for primary liver
cancer and certain other cancers metastatic to the liver and are uniquely positioned to treat the entire liver either as a standalone therapy or as a complement to other therapies. </P>

cash for its operating activities, which compares to $15.4&nbsp;million used for operating activities during the year ended December&nbsp;31, 2017.&nbsp;The increase of $0.7&nbsp;million was primarily driven by an increase in operating expenses
primarily related to the Company&#146;s clinical trial effort discussed in the Overview section above. In light of recent financing activities described below, the Company believes it has sufficient capital to fund its operating activities through
June 2019. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">Our consolidated financial statements as of December&nbsp;31, 2018 have been prepared under the assumption that we will
continue as a&nbsp;going concern&nbsp;for the next twelve months.&nbsp;We expect to incur significant expenses and operating losses for the foreseeable future. These factors raise substantial doubt about our ability to continue as a&nbsp;going
concern. Because Delcath&#146;s business does not generate positive cash flow from operating activities, the Company will need to obtain substantial additional capital in order to fund clinical trial research and support our development efforts and
to fully commercialize our product.&nbsp;The Company believes it will be able to raise additional capital in the event it is in its best interest to do so. The Company anticipates raising such additional capital by either selling shares of
Delcath&#146;s capital stock, borrowing money or entering into strategic alliances with appropriate partners. To the extent additional capital is not available when needed or on acceptable terms, the Company may be forced to abandon some or all of

million for the six months ended June 30, 2018. The decrease of $17.2 million is due to the reclassification of certain warrants from liability to equity in 2018 and the continued mark-to-market adjustments to the remaining Warrant liability as

Company&#146;s future results are subject to substantial risks and uncertainties. As noted above, Delcath has operated at a loss for its entire history and anticipates that losses will continue over the coming years. There can be no assurance that
Delcath will ever generate significant revenues or achieve profitability. The Company expects to use cash, cash equivalents and investment proceeds to fund its clinical and operating activities. Delcath&#146;s future liquidity and capital
requirements will depend on numerous factors, including the initiation and progress of clinical trials and research and product development programs; obtaining approvals and complying with regulations; the timing and effectiveness of product
commercialization activities, including marketing arrangements; the timing and costs involved in preparing, filing, prosecuting, defending and enforcing intellectual property rights; and the effect of competing technological and market developments.

significant expenses and operating losses for the foreseeable future. These factors raise substantial doubt about our ability to continue as a going concern. Because Delcath&#146;s business does
not generate positive cash flow from operating activities, the Company will need to obtain substantial additional capital in order to fund clinical trial research and support development efforts relating to Ocular Melanoma liver metastases, ICC, HCC
or other indications, and to fully commercialize the product. The Company believes it will be able to raise additional capital in the event it is in its best interest to do so. The Company anticipates raising such additional capital by either
borrowing money, selling shares of Delcath&#146;s capital stock, or entering into strategic alliances with appropriate partners. To the extent additional capital is not available when needed or on acceptable terms, the Company may be forced to
abandon some or all of its development and commercialization efforts, which would have a material adverse effect on the prospects of its business. Further, the Company&#146;s assumptions relating to its cash requirements may differ materially from
its actual requirements because of a number of factors, including significant unforeseen delays in the regulatory approval process, changes in the timing, scope, focus and direction of clinical trials and costs related to commercializing the

inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Level&nbsp;2 inputs are inputs other than quoted prices included in Level&nbsp;1 that are observable for the
asset or liability, either directly or indirectly. Level&nbsp;2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such
as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level&nbsp;3 inputs are unobservable inputs for the asset or liability which are typically based on an entity&#146;s own assumptions, as
there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire
fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company&#146;s assessment of the significance of a particular input to the fair value measurement in its entirety
requires judgment and considers factors specific to the asset or liability. See Note 12 to the Company&#146;s audited consolidated financial statements contained in our Annual Report on Form <FONT STYLE="white-space:nowrap">10-K</FONT> for assets
and liabilities the Company has evaluated under ASC 820. </P>

not for the purpose of expressing an opinion on the effectiveness of the Company&#146;s internal control over financial reporting. Accordingly, we express no such opinion. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">Delcath Systems, Inc. is an interventional oncology company focused on the treatment of primary and metastatic liver cancers. Our
investigational product, &#147;Melphalan Hydrochloride for Injection for use with the Delcath Hepatic Delivery System&#148; (&#147;Melphalan/HDS&#148;), is designed to administer high-dose chemotherapy to the liver while controlling systemic
exposure and associated side effects. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">Our primary research focus is on ocular melanoma liver metastases (&#147;mOM&#148;) and intrahepatic
cholangiocarcinoma (&#147;ICC&#148;) and certain other cancers that are metastatic to the liver. Currently there are few effective treatment options for certain cancers in the liver. Traditional treatment options include surgery, systemic
chemotherapy, liver transplant, radiation therapy, interventional radiology techniques, and isolated hepatic perfusion. We believe that Melphalan/HDS and CHEMOSAT represent a potentially important advancement in regional therapy for primary liver
cancer and certain other cancers metastatic to the liver and are uniquely positioned to treat the entire liver either as a standalone therapy or as a complement to other therapies. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">Our clinical development program for Melphalan/HDS is comprised of the FOCUS Clinical Trial for Patients with Hepatic Dominant Ocular Melanoma
(the &#147;FOCUS Trial&#148;), a global registration clinical trial that is investigating objective response rate in mOM, and the ALIGN Trial, a global Phase 3 clinical trial for ICC (the &#147;ALIGN Trial&#148;). Our product also includes a
registry for CHEMOSAT commercial cases performed in Europe and sponsorship of select Investigator Initiated Trials. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">While we currently
utilize third parties to manufacture some components of our product, we also have our own manufacturing operations for certain components of our product and assemble and package our products in Queensbury, New York. See the discussion in Part 1,
Item 1 under the caption &#147;Manufacturing and Quality Assurance&#148; above. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">We commercialize our product in Europe through alliances
with third parties. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman"><B>Liquidity </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the
satisfaction of liabilities in the normal course of business. As shown in the accompanying financial statements during the year ended December&nbsp;31, 2018, the Company incurred net losses of $19.2&nbsp;million and used $14.7&nbsp;million of cash
for its operating activities. These factors among others raise substantial doubt about the Company&#146;s ability to continue as a going concern for a reasonable period of time. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">The Company&#146;s existence is dependent upon management&#146;s ability to obtain additional funding sources or to enter into strategic
alliances. Adequate additional financing may not be available to us on acceptable terms, or at all. If the Company is unable to raise additional capital and/or enter into strategic alliances when needed or on attractive terms, it would be forced to
delay, reduce or eliminate our research and development programs or any commercialization efforts. There can be no assurance that the Company&#146;s efforts will result in the resolution of the Company&#146;s liquidity needs. If Delcath is not able
to continue as a going concern, it is likely that holders of its Common Stock will lose all of their investment. The accompanying consolidated financial statements do not include any adjustments that might result should the Company be unable to
continue as a going concern. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">The Company anticipates incurring additional losses until such time, if ever, that it can generate
significant sales. At December&nbsp;31, 2018, management believed that its capital resources were adequate to fund operations through March 2019. Additional working capital will be required to continue operations.

depreciation on a straight line basis over the estimated useful lives of the assets which range from three to seven years. Leasehold improvements will be amortized over the shorter of the lease term or the estimated useful life of the related assets
when they are placed into service. The Company evaluates property, plant and equipment for impairment periodically to determine if changes in circumstances or the occurrence of events suggest the carrying value of the asset or asset group may not be
recoverable. Maintenance and repairs are charged to operations as incurred. Expenditures which substantially increase the useful lives of the related assets are capitalized. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">The Company accounts for derivative instruments in accordance with Accounting Standards Codification (&#147;ASC&#148;) 815, Derivatives and
Hedging, which establishes accounting and reporting standards for derivative instruments and hedging activities, including certain derivative instruments embedded in other financial instruments or contracts and requires recognition of all
derivatives on the balance sheet at fair value, regardless of the hedging relationship designation. Accounting for changes in the fair value of the derivative instruments depends on whether the derivatives qualify as hedge relationships and the
types of relationships designated are based on the exposures hedged. At December&nbsp;31, 2018 and 2017, the Company did not have any derivative instruments that were designated as hedges. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman"><B><I>Fair Value Measurements </I></B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">The Company adheres to ASC 820, Fair Value Measurement, which defines fair value, establishes a framework for measuring fair value, and expands
disclosures about fair value measurements. ASC 820 applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements; accordingly, the standard does not require any new fair value
measurements of reported balances. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">ASC 820 emphasizes that fair value is a market-based measurement, not an entity-specific
measurement.&nbsp;Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability.&nbsp;As a basis for considering market participant assumptions in fair value
measurements, ASC 820 establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1
and 2 of the hierarchy) and the reporting entity&#146;s own assumptions about market participant assumptions (unobservable inputs classified within Level&nbsp;3 of the hierarchy). </P>

transfer control of the promised goods or services to our customers in an amount that reflects the consideration to which we expect to be entitled to in exchange for those goods or services. When obligations or contingencies remain after the
products are shipped, such as training and certifying the treatment centers, revenue is deferred until the obligations or contingencies are satisfied. </P>

standard in 2018 were not material to our consolidated financial statements. In assessing our revenue arrangements in accordance with ASC 606, Revenue from Contracts with Customers, we must identify the contract, determine the transaction price
including an estimation of any variable consideration we expect to receive in connection with the contract, identify the promises of goods or services to the customer and each distinct performance obligation, allocate the transaction price to each
of the performance obligations, and recognize revenue when or as the performance obligations are satisfied. Each of these steps in the revenue recognition process requires management to make judgements and/or estimates. The most significant
judgements and estimates involve the determination of variable consideration to be included in the transaction price. Variable consideration is recognized at an amount we believe is not subject to significant reversal and is adjusted at each
reporting period if the most likely amount of expected consideration changes or becomes fixed. We believe this provides a reasonable basis for recognizing revenue, however, actual results could differ from estimates and significant changes in
estimates could impact our results of operations in future periods. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman"><B><I>Deferred Revenue </I></B></P>

deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases. The
Company applies the accounting guidance issued to address the accounting for uncertain tax positions. This guidance clarifies the accounting for income taxes, by prescribing a minimum recognition threshold a tax position is required to meet before
being recognized in the financial statements as well as provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company classifies interest and penalty
expense related to uncertain tax positions as a component of income tax expense. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years that the asset is expected to be recovered or
the liability settled. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets depends on the generation of future
taxable income during the period in which related temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in its assessment of a
valuation allowance. See Note 14 for additional information. </P>

Early adoption was permitted, including interim periods within those fiscal years provided that those electing early adoption must adopt all of the amendments in the same period. The guidance requires application using a retrospective transition

number of optional practical expedients primarily focused on leases that commenced before the effective date of Topic 842, including continuing to account for leases that commence before the effective date in accordance with previous guidance,

LLC (Index No.&nbsp;651749/2019). The Action seeks expedited equitable relief in the form of reformation and a declaratory judgement to remedy a scrivener&#146;s error in the Series D Warrants issued in the Company&#146;s February 2018 public
offering such that those warrants do not contain a price and quantity ratchet upon a sale of Company securities at a price lower than the offering price in the February 2018 offering. The defendant, L1 Capital Global Opportunities Master Fund,
settled with the Company by exchanging its Series D Warrants for Company Common Stock on a <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">one-for-one</FONT></FONT> basis, which is the same ratio for which other investors in the
February 2018 round exchanged their Series D Warrants in December 2018. The Company and the remaining defendants in the Action, Iroquois Capital Investment Group LLC, Iroquois Master Fund Ltd. and First Fire Global Opportunities Fund LLC, entered
into a settlement agreement on April&nbsp;18, 2019, the full text of which is annexed as Exhibit 10.42 to our Annual Report on Form <FONT STYLE="white-space:nowrap">10-K,</FONT> pursuant to which such defendants surrendered the Series D Warrants and
waived all rights granted to them by or in connection with the Series D Warrants and all rights afforded to them to participate in the Company&#146;s future Common Stock offerings. In consideration therefor, pursuant to the settlement agreement,
(i)&nbsp;the Company paid <FONT STYLE="white-space:nowrap">one-fifth</FONT> of the reasonable fees and expenses of defendants&#146; counsel incurred in connection with the Action and negotiation of the settlement agreement, the total of which shall

State Supreme Court, New York County alleging breaches by the Company of Hudson Bay&#146;s rights of participation in future Company offerings granted in the September 2017 Securities Purchase Agreement between the Company and Hudson Bay and in the
February 2018 Securities Purchase Agreement among, inter alia, the Company and Hudson Bay. In terms of relief sought, Hudson Bay claimed both monetary damages (which it claims to be in excess of $1 million) and specific performance. The Company
denied any liability with respect to the claims set forth in the lawsuit. As previously reported, on January&nbsp;4, 2019, the Company was notified by its litigation counsel that on December&nbsp;28, 2018, the Suit was dismissed with prejudice by
the filing of a Stipulation for Discontinuance in the New York State Supreme Court, New York County. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">On May&nbsp;9, 2018, the Company

tax purposes of approximately $230.0&nbsp;million and $211.3&nbsp;million respectively. A significant portion of the federal amount is subject to an annual limitation as low as $27,500 as a result of changes in the Company&#146;s ownership in May
2003, November 2016, and multiple dates throughout 2017 and 2018, as defined by Federal Internal Revenue Code Section&nbsp;382 and the related income tax regulations. As a result of the limitations caused by the May 2003, November 2016 and multiple
2017 and 2018 ownership changes, approximately $208.1&nbsp;million of the total net operating loss carryforwards is expected to expire unutilized and will be unavailable to offset future federal taxable income. Approximately $21.9&nbsp;million of
net operating loss carryforwards remains available to offset future federal taxable income, of which $1.7&nbsp;million will expire between 2019 and 2037 and $20.2&nbsp;million will have an unlimited carryforward period as a result of the Tax Cuts
and Jobs Act. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">In addition, the Company&#146;s state net operating losses are also subject to annual limitations that generally follow the
federal Section&nbsp;382 provisions (with the exception of Connecticut), adjusted for each state&#146;s respective income apportionment percentages. As of December&nbsp;31, 2018 and 2017, the Company had net operating loss carryforwards for state
and city income tax purposes between approximately $27.3&nbsp;million and $167.3&nbsp;million and between approximately $27.3&nbsp;million and $150.3&nbsp;million, respectively, which expire through 2038. As a result of the 382 limitations,
approximately $157.2&nbsp;million and $141.5 million of New York State and New York City net operating losses are expected to expire unutilized and will be unavailable to offset future taxable income. Approximately $10.1&nbsp;million and
$10.1&nbsp;million of net operating loss carryforwards, respectively, will be available to offset future state and city taxable income. As of December&nbsp;31, 2018 and 2017 the Company had a net operating loss carryforward for foreign income tax
purposes of $25.2&nbsp;million and $25.0&nbsp;million, respectively, which have indefinite carryforward periods. As of December&nbsp;31, 2018 and 2017, the Company had federal research and development tax credit carryforwards of approximately
$5.0&nbsp;million and $4.3&nbsp;million respectively, which expire through 2038. As a result of the section 382 limitations, all but $0.2&nbsp;million of the tax credit carryforwards is expected to expire unutilized. </P>

</TABLE> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">On December&nbsp;22, 2017, the United States enacted the Tax Cuts and Jobs Act (the &#147;Act&#148;). The Act,
which is also commonly referred to as &#147;U.S. tax reform&#148;, significantly changes U.S. corporate income tax laws by, among other provisions, reducing the maximum U.S. corporate income tax rate from 35% to 21% starting in 2018. During the year
ended December&nbsp;31, 2017, the Company reduced deferred tax assets by a provisional amount of $143,500, offset by a corresponding reduction to its valuation allowance, as a result of the <FONT STYLE="white-space:nowrap">re-measurement</FONT> of
deferred tax assets and liabilities from its 34% effective rate under existing law to the new lower statutory rate of 21%. The Company finalized its accounting of the effects of tax reform in 2018, which resulted in insignificant adjustments. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">The Act also requires a mandatory <FONT STYLE="white-space:nowrap">one-time</FONT> inclusion of the deferred foreign income of controlled
foreign corporations. The <FONT STYLE="white-space:nowrap">one-time</FONT> transition tax is based on Delcath&#146;s total post-1986 earnings and profits (E&amp;P) for which the Company has previously deferred from U.S. income taxes. During the year
ended December&nbsp;31, 2017, the Company&#146;s reasonable estimate resulted in no provisional amount for the <FONT STYLE="white-space:nowrap">one-time</FONT> transition tax liability, as the Company&#146;s international subsidiaries are expected
to have a cumulative deficit in E&amp;P. As the Company&#146;s international subsidiaries have a cumulative deficit in earnings and profits, the Company did not anticipate being affected by the mandatory inclusion provisions of the Act. The Company
finalized its calculation of the total post-1986 foreign E&amp;P (including deficits) for these foreign subsidiaries during 2018 and was not impacted by the mandatory inclusion provisions of the Act. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">On December, 22, 2017, Staff Accounting Bulletin 118 was issued due to the complexities involved in accounting for the recently enacted Act.
SAB 118 requires the Company to include in its financial statements a reasonable estimate of the impact of the Act on earnings to the extent such estimate has been determined. Accordingly, the U.S. provision for income tax for December&nbsp;31, 2017
was based on the reasonable estimate guidance provided by SAB 118. The Company finalized the impact from the Act and recorded insignificant adjustments. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">The Company complies with the provisions of ASC <FONT STYLE="white-space:nowrap">740-10,</FONT> Income Taxes, in accounting for its uncertain
tax positions. ASC <FONT STYLE="white-space:nowrap">740-10</FONT> addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under ASC <FONT
STYLE="white-space:nowrap">740-10,</FONT> the Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the
technical merits of the position. The Company has determined that the Company has no significant uncertain tax positions requiring recognition under ASC <FONT STYLE="white-space:nowrap">740-10</FONT> and therefore has not included a tabular
rollforward of unrecognized tax benefits. As there are no uncertain tax positions recognized, interest and penalties have not been accrued. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">The Company is subject to income tax in the U.S., as well as various state and international jurisdictions. The Company has not been audited by
any state tax authorities in connection with income taxes. The Company has not been audited by international tax authorities or any states in connection with income taxes. The Company&#146;s New York State tax returns have been subject to annual

December&nbsp;31, 2015; tax years ending December&nbsp;31, 2015 through December&nbsp;31, 2018 remain open to examination. The Republic of Ireland is the Company&#146;s only significant foreign jurisdiction. The Company is no longer subject to
Ireland tax examination for tax years ending prior to December&nbsp;31, 2014 (as Ireland has not initiated an audit of 2013 as of December&nbsp;31, 2018); tax years ending December&nbsp;31, 2014 through December&nbsp;31, 2018 remain open to

utilized or expire prior to utilization, and the applicable statutes of limitation have expired in the utilization year. The federal and state tax authorities can generally reduce a net operating loss (but not create taxable income) for a period
outside the statute of limitations in order to determine the correct amount of net operating loss which may be allowed as a deduction against income for a period within the statute of limitations. </P>

Backstop Commitment Purchase Agreements with four institutional investors, by their mutual agreement. The Company and such institutional investors entered into Backstop Commitment Purchase Agreements in connection with a rights offering conducted by
the Company that closed in September 2018 in which the Company proposed to raise up to $50&nbsp;million by distributing, at no charge, to holders of its Common Stock <FONT STYLE="white-space:nowrap">non-transferable</FONT> rights to subscribe for
and purchase shares of the Company&#146;s Common Stock at a price of $1.75 per share (the &#147;Subscription Price&#148;). Pursuant to the Backstop Commitment Purchase Agreements, such institutional investors agreed to purchase, at the Subscription
Price, shares not issued in the rights offering following the expiration of the rights offering subscription period, subject to certain conditions, including the requirement that the closing price of a share of the Company&#146;s Common Stock as
reported by the OTCQB or higher market for each of the five business days immediately preceding a purchase exceeded the Subscription Price. The Backstop Commitment Purchase Agreements were terminated by mutual agreement of the parties thereto due to
the fact that the closing price of the Company&#146;s Common Stock had not exceeded the Subscription Price since October&nbsp;1, 2018 and, thus, the institutional investors had no obligation to purchase shares. </P>

two institutional investors and issued promissory notes to the investors. The promissory notes have an aggregate principal amount of $3.3&nbsp;million, bear interest at the rate of 8% per annum and are due six months from the issuance of each note.

investigational product&#151;Melphalan Hydrochloride for Injection for use with the Delcath Hepatic Delivery System (&#147;Melphalan/HDS&#148;)&#151;is designed to administer high-dose chemotherapy to the liver while controlling systemic exposure
and associated side effects. In Europe, our system is commercially available under the trade name Delcath Hepatic CHEMOSAT <SUP STYLE="font-size:85%; vertical-align:top">&reg;</SUP> Delivery System for Melphalan (&#147;CHEMOSAT&#148;), where it has

metastases (&#147;mOM&#148;) and intrahepatic cholangiocarcinoma (&#147;ICC&#148;), a type of primary liver cancer, and certain other cancers that are metastatic to the liver. We believe the disease states we are investigating represent a
multi-billion dollar global market opportunity and a clear unmet medical need. </P> <P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">Our clinical development program (&#147;CDP&#148;) for

a global Phase 3 clinical trial for ICC (the &#147;ALIGN Trial&#148;). Our CDP also includes a registry for CHEMOSAT commercial cases performed in Europe and sponsorship of select investigator-initiated trials (&#147;IITs&#148;). </P>

in the Company&#146;s February 2018 public offering such that those warrants did not contain a price and quantity ratchet upon a sale of Company securities at a price lower than the offering price in the offering. The defendant, L1 Capital Global
Opportunities Master Fund, settled with the Company by exchanging its Series D Warrants for the Company&#146;s common stock on a <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">one-for-one</FONT></FONT> basis, which is the same
ratio for which other investors in the February 2018 round exchanged their Series D Warrants in December 2018. The Company and the remaining defendants in the Action, Iroquois Capital Investment Group LLC, Iroquois Master Fund Ltd. and First Fire
Global Opportunities Fund LLC, entered into a settlement agreement on April&nbsp;18, 2019 pursuant to which such defendants surrendered their Series D Warrants and waived all rights granted to them by or in connection with the Series D Warrants and
all rights afforded to them to participate in the Company&#146;s future common stock offerings. In consideration therefor, pursuant to the settlement agreement, (i)&nbsp;the Company paid <FONT STYLE="white-space:nowrap">one-fifth</FONT> of the
reasonable fees and expenses of defendants&#146; counsel incurred in connection with the Action and negotiation of the settlement agreement, the total of which shall not exceed $50,000 (the &#147;Settlement Fees&#148;) and (ii)&nbsp;subject to the
Company securing and closing certain contemplated financing, the Company agreed to pay to the defendants $400,000 and the remaining Settlement Fees. On July&nbsp;17, 2019, the Company paid the amount of $440,000 to the defendants pursuant to the
settlement agreement from the net proceeds received by the Company in the closing of a private placement transaction discussed in Note 14 below. No amounts remain payable under the settlement and the Action is now fully settled. </P>

director of the corporation will not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except where the director breached the duty of loyalty, failed to act in good faith,
engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit. Our amended and restated certificate
of incorporation provides for this limitation of liability. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Section&nbsp;145 of the DGCL, or Section&nbsp;145, provides that a Delaware corporation may

corporation), by reason of the fact that such person is or was an officer, director, employee or agent of such corporation or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or

acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation&#146;s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was
illegal. A Delaware corporation may indemnify any persons who are, were or are a party to any threatened, pending or completed action or suit by or in the right of the corporation by reason of the fact that such person is or was a director, officer,
employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys&#146; fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit, provided
such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation&#146;s best interests, provided that no indemnification is permitted without judicial approval if the officer, director, employee or
agent is adjudged to be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses which such officer or
director has actually and reasonably incurred. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Section&nbsp;145 further authorizes a corporation to purchase and maintain insurance on behalf of any

directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final
adjudication of such issue. </P>

    These interim condensed consolidated financial statements are
    unaudited and were prepared by the Company in accordance with
    generally accepted accounting principles in the United States of
    America (GAAP) and with the SEC&amp;#x2019;s instructions to Form
    &lt;font style="WHITE-SPACE: nowrap"&gt;10-Q&lt;/font&gt; and Article 10 of
    Regulation &lt;font style="WHITE-SPACE: nowrap"&gt;S-X.&lt;/font&gt; They
    include the accounts of all entities controlled by Delcath and all
    significant inter-company accounts and transactions have been
    eliminated in consolidation.&lt;/p&gt;

    The preparation of interim condensed consolidated financial
    statements requires management to make assumptions and estimates
    that impact the amounts reported. These interim condensed
    consolidated financial statements, in the opinion of management,
    reflect all adjustments, consisting of normal recurring accruals,
    necessary for a fair presentation of the Company&amp;#x2019;s results of
    operations, financial position and cash flows for the interim
    periods ended June&amp;#xA0;30, 2019 and 2018; however, certain
    information and footnote disclosures normally included in our
    Annual Report have been condensed or omitted as permitted by GAAP.
    It is important to note that the Company&amp;#x2019;s results of
    operations and cash flows for interim periods are not necessarily
    indicative of the results of operations and cash flows to be
    expected for a full fiscal year or any interim period.&lt;/p&gt;

    As previously reported, on March&amp;#xA0;26, 2019, the Company
    commenced an action (the &amp;#x201C;Action&amp;#x201D;) in the Commercial
    Division of the Supreme Court for the State of New York, County of
    New York, captioned &lt;u&gt;Delcath Systems, Inc., v. Iroquois Capital
    Investment Group LLC, Iroquois Master Fund Ltd., L1 Capital Global
    Opportunities Master Fund and First Fire Global&lt;/u&gt;
    &lt;u&gt;Opportunities Fund LLC&lt;/u&gt; (Index No.&amp;#xA0;651749/2019). The
    Action sought expedited equitable relief in the form of reformation
    and a declaratory judgement to remedy a scrivener&amp;#x2019;s error
    made in connection with the Series D Warrants issued in the
    Company&amp;#x2019;s February 2018 public offering such that those
    warrants did not contain a price and quantity ratchet upon a sale
    of Company securities at a price lower than the offering price in
    the offering. The defendant, L1 Capital Global Opportunities Master
    Fund, settled with the Company by exchanging its Series D Warrants
    for the Company&amp;#x2019;s common stock on a &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;one-for-one&lt;/font&gt;&lt;/font&gt; basis, which is the
    same ratio for which other investors in the February 2018 round
    exchanged their Series D Warrants in December 2018. The Company and
    the remaining defendants in the Action, Iroquois Capital Investment
    Group LLC, Iroquois Master Fund Ltd. and First Fire Global
    Opportunities Fund LLC, entered into a settlement agreement on
    April&amp;#xA0;18, 2019 pursuant to which such defendants surrendered
    their Series D Warrants and waived all rights granted to them by or
    in connection with the Series D Warrants and all rights afforded to
    them to participate in the Company&amp;#x2019;s future common stock
    offerings. In consideration therefor, pursuant to the settlement
    agreement, (i)&amp;#xA0;the Company paid &lt;font style="WHITE-SPACE: nowrap"&gt;one-fifth&lt;/font&gt; of the reasonable fees and
    expenses of defendants&amp;#x2019; counsel incurred in connection with
    the Action and negotiation of the settlement agreement, the total
    of which shall not exceed $50,000 (the &amp;#x201C;Settlement
    Fees&amp;#x201D;) and (ii)&amp;#xA0;subject to the Company securing and
    closing certain contemplated financing, the Company agreed to pay
    to the defendants $400,000 and the remaining Settlement Fees. On
    July&amp;#xA0;17, 2019, the Company paid the amount of $440,000 to the
    defendants pursuant to the settlement agreement from the net
    proceeds received by the Company in the closing of a private
    placement transaction discussed in Note 14 below. No amounts remain
    payable under the settlement and the Action is now fully
    settled.&lt;/p&gt;

    On May&amp;#xA0;9, 2018, the Company received a Demand Letter from UBC
    for an outstanding balance owed at that time by the Company to UBC
    of $2.1&amp;#xA0;million. The Company has worked with UBC since that
    time to establish a payment plan for the balance owed.&lt;/p&gt;

    On April&amp;#xA0;19, 2019, April&amp;#xA0;26, 2019, May&amp;#xA0;9, 2019 and
    May&amp;#xA0;23, 2019, the Company issued 8% senior secured notes
    (collectively, the &amp;#x201C;2019 Notes&amp;#x201D;) in the aggregate
    principal amount of $3.3&amp;#xA0;million, to two institutional
    investors. The 2019 Notes bore interest at the rate of 8% per annum
    and were to mature on the six month anniversary of issuance in each
    case. The 2019 Notes were not convertible. The 2019 Notes contained
    standard events of default and remedies and are secured by a lien
    on the Company&amp;#x2019;s assets. The 2019 Notes were exchanged as
    part of the recent equity financing discussed further in Note 14
    and are no longer outstanding.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In March 2019, the Company exchanged all issued and outstanding
    shares of its Series D Preferred Stock (having an aggregate stated
    value of $1,160,000) and received $400,000 in cash proceeds in
    exchange for a senior secured promissory note (the &amp;#x201C;March
    2019 Note&amp;#x201D;) in the principal amount of $1,560,000. The March
    2019 Note bore interest at the rate of 8% per annum, and were to
    mature on April&amp;#xA0;1, 2020, and was not convertible. The
    principal is recognized in notes payable on the Condensed
    Consolidated Balance Sheet. The March 2019 Note was exchanged as
    part of the recent equity financing discussed further in Note 14
    and is no longer outstanding.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On June&amp;#xA0;4, 2018, July&amp;#xA0;21, 2018, August&amp;#xA0;29, 2018, and
    September&amp;#xA0;21, 2018, the Company issued 8% senior secured
    convertible notes (collectively, &amp;#x201C;the 2018 Notes&amp;#x201D;) in
    the aggregate principal amount of $9.4&amp;#xA0;million to several
    institutional investors. The 2018 Notes bore interest at the rate
    of 8% per annum and had maturity dates between December 2018 and
    March 2021. The 2018 Notes were initially convertible and secured
    pursuant to a Security Agreement which created a first priority
    security interest in all of the personal property (other than
    Excluded Collateral as defined in the Security Agreement) of the
    Company of every kind and description, tangible or intangible,
    whether currently owned and existing or created or acquired in the
    future. In March 2019, the Company amended the June 2018, July 2018
    and August 2018 Notes to make them &lt;font style="WHITE-SPACE: nowrap"&gt;non-convertible.&lt;/font&gt; There was no impact
    to the financial statements. In April 2019, the Company received
    notices of default from the investors in the 2018 Notes which
    resulted in a 25%, or $1.1&amp;#xA0;million, increase in principal and
    an increase in the interest rates from 8% to 18%. The 2018 Notes
    were exchanged as part of the recent equity financing discussed
    further in Note 14 and are no longer outstanding.&lt;/p&gt;

    Basic net loss per share is determined by dividing net loss by the
    weighted average shares of common stock outstanding during the
    period, without consideration of potentially dilutive securities
    except for those shares that are issuable for little or no cash
    consideration. Diluted net loss per share is determined by dividing
    net loss by diluted weighted average shares outstanding. Diluted
    weighted average shares reflects the dilutive effect, if any, of
    potentially dilutive common shares, such as stock options and
    warrants calculated using the treasury stock method. In periods
    with reported net operating losses, all common stock options and
    warrants are generally deemed anti-dilutive such that basic net
    loss per share and diluted net loss per share are equal. However,
    in certain periods in which the exercise price of the warrants was
    less than the last reported sales price of Delcath&amp;#x2019;s common
    stock on the final trading day of the period and there is a gain
    recorded pursuant to the change in fair value of the warrant
    derivative liability, the impact of gains related to the
    &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;mark-to-market&lt;/font&gt;&lt;/font&gt; adjustment of
    the warrants outstanding at the end of the period is reversed and
    the treasury stock method is used to determine diluted earnings per
    share.&lt;/p&gt;

    At June&amp;#xA0;30, 2019, the Company had a total of 125,000 February

    &amp;#x201C;Legal Proceedings&amp;#x201D; and in Note 12 to the
    Company&amp;#x2019;s condensed consolidated financial statements
    contained in this Quarterly Report on Form &lt;font style="WHITE-SPACE: nowrap"&gt;10-Q,&lt;/font&gt; the February 2018 Warrants were
    surrendered pursuant to a settlement agreement entered into between

    on April&amp;#xA0;18, 2019 and final payment under the settlement was

    Warrants at June&amp;#xA0;30, 2019 and December&amp;#xA0;31, 2018 was
    determined by using option pricing models with the following

    As discussed in Note 14 &lt;i&gt;Income Taxes&lt;/i&gt; to the Consolidated
    Financial Statements included in the Company&amp;#x2019;s Annual Report
    filed for the fiscal year ended December&amp;#xA0;31, 2018, the Company
    has a valuation allowance against the full amount of its net
    deferred tax assets. The Company currently provides a valuation
    allowance against deferred tax assets when it is more likely than
    not that some portion or all of its deferred tax assets will not be
    realized. The Company has not recognized any unrecognized tax
    benefits in its balance sheet.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company is subject to income tax in the U.S., as well as
    various state and international jurisdictions. The federal and
    state tax authorities can generally reduce a net operating loss
    (but not create taxable income) for a period outside the statute of
    limitations in order to determine the correct amount of net
    operating loss which may be allowed as a deduction against income
    for a period within the statute of limitations. Additional
    information regarding the statutes of limitations can be found in
    Note 14 &lt;i&gt;Income Taxes&lt;/i&gt; to the Consolidated Financial
    Statements included in the Company&amp;#x2019;s Annual Report filed for
    the fiscal year ended December&amp;#xA0;31, 2018.&lt;/p&gt;

    Statement&amp;#x2014;Reporting Comprehensive Income (Topic 220). ASU
    &lt;font style="WHITE-SPACE: nowrap"&gt;2018-02&lt;/font&gt; allows a company
    to elect a reclassification from accumulated other comprehensive
    income to retained earnings for stranded tax effects resulting from
    the Tax Cuts and Jobs Act. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2018-02&lt;/font&gt; is effective for periods
    beginning after December&amp;#xA0;15, 2018. Upon adoption of ASU
    &lt;font style="WHITE-SPACE: nowrap"&gt;2018-02,&lt;/font&gt; the Company did
    not elect to reclassify the tax effects of the Tax Cuts and Jobs
    Act from accumulated other comprehensive income to retained
    earnings, as the stranded tax effects were insignificant.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;

    January&amp;#xA0;1, 2019, electing the practical expedients and
    applying the transition provisions as of the effective date.
    Reporting periods beginning on or after January&amp;#xA0;1, 2019 are
    presented under Topic 842, while prior period amounts, as reported
    under previous GAAP, were not adjusted. The adoption of Topic 842
    on January&amp;#xA0;1, 2019 did not have a significant impact on the

    Delcath Systems, Inc. is an interventional oncology company focused
    on the treatment of primary and metastatic liver cancers. Our
    investigational product&amp;#x2014;Melphalan Hydrochloride for Injection
    for use with the Delcath Hepatic Delivery System
    (&amp;#x201C;Melphalan/HDS&amp;#x201D;)&amp;#x2014;is designed to administer
    high-dose chemotherapy to the liver while controlling systemic
    exposure and associated side effects. In Europe, our system is
    commercially available under the trade name Delcath Hepatic
    CHEMOSAT &lt;sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top"&gt;&amp;#xAE;&lt;/sup&gt; Delivery System
    for Melphalan (&amp;#x201C;CHEMOSAT&amp;#x201D;), where it has been used at
    major medical centers to treat a wide range of cancers of the
    liver.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Our primary research focus is on ocular melanoma liver metastases
    (&amp;#x201C;mOM&amp;#x201D;) and intrahepatic cholangiocarcinoma
    (&amp;#x201C;ICC&amp;#x201D;), a type of primary liver cancer, and certain
    other cancers that are metastatic to the liver. We believe the
    disease states we are investigating represent a multi-billion
    dollar global market opportunity and a clear unmet medical
    need.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Our clinical development program (&amp;#x201C;CDP&amp;#x201D;) for
    Melphalan/HDS is comprised of The FOCUS Clinical Trial for Patients
    with Hepatic Dominant Ocular Melanoma (the &amp;#x201C;FOCUS
    Trial&amp;#x201D;), a global registration clinical trial that is
    investigating objective response rate in mOM, and the ALIGN Trial,
    a global Phase 3 clinical trial for ICC (the &amp;#x201C;ALIGN
    Trial&amp;#x201D;). Our CDP also includes a registry for CHEMOSAT
    commercial cases performed in Europe and sponsorship of select
    investigator-initiated trials (&amp;#x201C;IITs&amp;#x201D;).&lt;/p&gt;

    The accompanying interim condensed consolidated financial
    statements have been prepared on a going concern basis, which
    contemplates the realization of assets and the satisfaction of
    liabilities in the normal course of business. The Company has
    incurred losses since inception and expects to continue incurring
    losses for the next several years. These losses, among other
    factors, raise substantial doubt about the Company&amp;#x2019;s ability
    to continue as a going concern.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company&amp;#x2019;s existence is dependent upon management&amp;#x2019;s
    ability to obtain additional funding sources or to enter into
    strategic alliances. There can be no assurance that the
    Company&amp;#x2019;s efforts will result in the resolution of the
    Company&amp;#x2019;s liquidity needs. The accompanying statements do not
    include any adjustments that might result should the Company be
    unable to continue as a going concern.&lt;/p&gt;

    These interim condensed consolidated financial statements are
    unaudited and were prepared by the Company in accordance with
    generally accepted accounting principles in the United States of
    America (GAAP) and with the SEC&amp;#x2019;s instructions to Form
    &lt;font style="WHITE-SPACE: nowrap"&gt;10-Q&lt;/font&gt; and Article 10 of
    Regulation &lt;font style="WHITE-SPACE: nowrap"&gt;S-X.&lt;/font&gt; They
    include the accounts of all entities controlled by Delcath and all
    significant inter-company accounts and transactions have been
    eliminated in consolidation.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 6px"&gt;

    The preparation of interim condensed consolidated financial
    statements requires management to make assumptions and estimates
    that impact the amounts reported. These interim condensed
    consolidated financial statements, in the opinion of management,
    reflect all adjustments, consisting of normal recurring accruals,
    necessary for a fair presentation of the Company&amp;#x2019;s results of
    operations, financial position and cash flows for the interim
    periods ended June&amp;#xA0;30, 2019 and 2018; however, certain
    information and footnote disclosures normally included in our
    Annual Report have been condensed or omitted as permitted by GAAP.
    It is important to note that the Company&amp;#x2019;s results of
    operations and cash flows for interim periods are not necessarily
    indicative of the results of operations and cash flows to be
    expected for a full fiscal year or any interim period.&lt;/p&gt;

    A description of our significant accounting policies has been
    provided in Note 3 &lt;i&gt;Summary of Significant Accounting

    In February 2018, the Financial Accounting Standards Board (the
    &amp;#x201C;FASB&amp;#x201D;) issued Accounting Standards Update

    &lt;font style="WHITE-SPACE: nowrap"&gt;2018-02&lt;/font&gt; allows a company

    In February 2016, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-02,&lt;/font&gt; Leases (Topic 842) effective
    January&amp;#xA0;1, 2019, electing the practical expedients and
    applying the transition provisions as of the effective date.
    Reporting periods beginning on or after January&amp;#xA0;1, 2019 are
    presented under Topic 842, while prior period amounts, as reported
    under previous GAAP, were not adjusted. The adoption of Topic 842
    on January&amp;#xA0;1, 2019 did not have a significant impact on the
    Company&amp;#x2019;s consolidated results of operations or cash
    flows.&lt;/p&gt;

    Basic net loss per share is determined by dividing net loss by the
    weighted average shares of common stock outstanding during the
    period, without consideration of potentially dilutive securities
    except for those shares that are issuable for little or no cash
    consideration. Diluted net loss per share is determined by dividing
    net loss by diluted weighted average shares outstanding. Diluted
    weighted average shares reflects the dilutive effect, if any, of
    potentially dilutive common shares, such as stock options and
    warrants calculated using the treasury stock method. In periods
    with reported net operating losses, all common stock options and
    warrants are generally deemed anti-dilutive such that basic net
    loss per share and diluted net loss per share are equal. However,
    in certain periods in which the exercise price of the warrants was
    less than the last reported sales price of Delcath&amp;#x2019;s common
    stock on the final trading day of the period and there is a gain
    recorded pursuant to the change in fair value of the warrant
    derivative liability, the impact of gains related to the
    &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;mark-to-market&lt;/font&gt;&lt;/font&gt; adjustment of
    the warrants outstanding at the end of the period is reversed and
    the treasury stock method is used to determine diluted earnings per
    share.&lt;/p&gt;

    On June&amp;#xA0;6, 2019, the Company entered into an agreement with
    two institutional investors, pursuant to which the investors agreed
    to transfer and surrender to the Company for cancellation of
    warrants to purchase 3.9&amp;#xA0;million shares of the Company&amp;#x2019;s
    common stock (the &amp;#x201C;Series D Warrants&amp;#x201D;) and warrants to
    purchase 53.4&amp;#xA0;million shares of the Company&amp;#x2019;s common
    stock (the &lt;font style="WHITE-SPACE: nowrap"&gt;&amp;#x201C;Pre-Funded&lt;/font&gt; Series D
    Warrants&amp;#x201D;). Under the terms of the Purchase Agreement, the
    investors agreed to defer the payment of the purchase price for the
    Series D Warrants and &lt;font style="WHITE-SPACE: nowrap"&gt;Pre-Funded&lt;/font&gt; Series D Warrants and,
    accordingly, the Company agreed to sell and issue to the investors
    8% Senior Secured Promissory Notes in an aggregate principal amount
    of $2&amp;#xA0;million in full payment and satisfaction of the purchase
    price for the Series D Warrants and &lt;font style="WHITE-SPACE: nowrap"&gt;Pre-Funded&lt;/font&gt; Series D Warrants. This
    agreement was effective upon the closing of the Company&amp;#x2019;s
    Private Placement discussed below.&lt;/p&gt;

    On July&amp;#xA0;11, 2019 and August&amp;#xA0;15, 2019, the Company and certain accredited investors
    entered into securities purchase agreements (the &amp;#x201C;Securities Purchase Agreements&amp;#x201D;) pursuant to which the
    Company sold to investors an aggregate of 20,000 shares of Series E
    Convertible Preferred Stock, par value $0.01 per share and 9,510 shares of Series E-1 Convertible Preferred Stock,
    par value $0.01 per share, having the rights and privileges described in the
    Company&amp;#x2019;s certificate of designations for such Series E Convertible Preferred Stock and Series E-1 Convertible Preferred Stock,
    at a price of $1,000 per share.
    Pursuant to the Securities Purchase Agreements,
    the Company also issued to each Investor a warrant (a &amp;#x201C;2019 Warrant&amp;#x201D;) to purchase a
    number of shares of common stock of the Company, equal to the
    number of shares of common stock issuable upon conversion of the
    Series E Preferred Stock purchased by the investor. Each 2019 Warrant has an exercise
    price of $0.06, subject to adjustment in accordance with the terms
    of the 2019 Warrants (the &amp;#x201C;Exercise Price&amp;#x201D;), and is exercisable at any time beginning on
  the date that the Company effects a reverse stock split until 5:00
  p.m. (NYC time) on the fifth anniversary of the date of the reverse
  stock split. The Company received gross proceeds from the private
  placements of $29.5&amp;#xA0;million, before deducting cash fees in the
    amount of $2.2&amp;#xA0;million payable to Roth Capital Partners, LLC
    (&amp;#x201C;Roth&amp;#x201D;) for serving as placement agent and cash fees
    in the amount of $0.6&amp;#xA0;million payable to Roth for serving as
    placement agent for certain prior securities offerings by the
    Company, and other transaction costs, fees and expenses payable by
    the Company.&lt;/p&gt;

    On November&amp;#xA0;5, 2018, the Company&amp;#x2019;s Board authorized the
    establishment of a new series of preferred stock designated as
    Series D Preferred Stock, $0.01 par value, the terms of which are
    set forth in the certificate of designations for such series of
    Preferred Stock. On March&amp;#xA0;29, 2019, the Company exchanged all
    issued and outstanding shares of its Series D Preferred Stock
    (having an aggregate stated value of $1,160,000) and received
    $400,000 in cash proceeds in exchange for the issuance of the March
    2019 Notes. Please see the discussion under Note 8 above.&lt;/p&gt;

    pursuant to the exercise of &lt;font style="WHITE-SPACE: nowrap"&gt;Pre-Funded&lt;/font&gt; Series D Warrants that were

    In April 2019, the Company entered into an exchange agreement with
    an institutional investor with respect to warrants held by such
    investor (the &amp;#x201C;February 2018 Warrants&amp;#x201D;). The February
    2018 Warrants were issued to several institutional investors as
    part of the Company&amp;#x2019;s February 2018 sale of the
    Company&amp;#x2019;s common stock and the issuance of warrants to
    purchase common shares. Pursuant to the exchange agreement, the
    Company issued 64,000 shares of the Company&amp;#x2019;s common stock
    (the &amp;#x201C;Exchange Shares&amp;#x201D;) in exchange for the February
    2018 Warrants. The exchange resulted in a loss of approximately
    $6,000 which is recognized in the statement of operations.&lt;/p&gt;

    The Company&amp;#x2019;s 2019 Equity Incentive Plan (the
    &amp;#x201C;Plan&amp;#x201D;) allows for grants in the form of incentive
    stock options, nonqualified stock options, stock units, stock
    awards, stock appreciation rights, and other stock-based awards.
    All of the Company&amp;#x2019;s officers, directors, employees,
    consultants and advisors are eligible to receive grants under the
    Plan. The maximum number of shares reserved for issuance under the
    Plan is 1,500,000. Options to purchase shares of common stock are
    granted at exercise prices not less than 100% of fair value on the
    dates of grant. As of June&amp;#xA0;30, 2019, the Plan had
    approximately 333,333 shares available for grant.&lt;/p&gt;

    The accompanying interim condensed consolidated financial
    statements have been prepared on a going concern basis, which
    contemplates the realization of assets and the satisfaction of
    liabilities in the normal course of business. The Company has
    incurred losses since inception and expects to continue incurring
    losses for the next several years. These losses, among other
    factors, raise substantial doubt about the Company&amp;#x2019;s ability
    to continue as a going concern.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company&amp;#x2019;s existence is dependent upon management&amp;#x2019;s
    ability to obtain additional funding sources or to enter into
    strategic alliances. There can be no assurance that the
    Company&amp;#x2019;s efforts will result in the resolution of the
    Company&amp;#x2019;s liquidity needs. The accompanying statements do not
    include any adjustments that might result should the Company be
    unable to continue as a going concern.&lt;/p&gt;

    (&amp;#x201C;ROU&amp;#x201D;) assets and lease liabilities when it obtains
    the right to control an asset under a leasing arrangement with an
    initial term greater than twelve months. The Company leases its
    facilities under &lt;font style="WHITE-SPACE: nowrap"&gt;non-cancellable&lt;/font&gt; operating and

    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company evaluates the nature of each lease at the inception of
    an arrangement to determine whether it is an operating or financing
    lease and recognizes the ROU asset and lease liabilities based on
    the present value of future minimum lease payments over the
    expected lease term. The Company&amp;#x2019;s leases do not generally
    contain an implicit interest rate and therefore the Company uses
    the incremental borrowing rate it would expect to pay to borrow on
    a similar collateralized basis over a similar term in order to
    determine the present value of its lease payments.&lt;/p&gt;

    Delcath Systems, Inc. is an interventional oncology company focused
    on the treatment of primary and metastatic liver cancers. Our
    investigational product, &amp;#x201C;Melphalan Hydrochloride for
    Injection for use with the Delcath Hepatic Delivery System&amp;#x201D;
    (&amp;#x201C;Melphalan/HDS&amp;#x201D;), is designed to administer high-dose
    chemotherapy to the liver while controlling systemic exposure and
    associated side effects.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Our primary research focus is on ocular melanoma liver metastases
    (&amp;#x201C;mOM&amp;#x201D;) and intrahepatic cholangiocarcinoma
    (&amp;#x201C;ICC&amp;#x201D;) and certain other cancers that are metastatic
    to the liver. Currently there are few effective treatment options
    for certain cancers in the liver. Traditional treatment options
    include surgery, systemic chemotherapy, liver transplant, radiation
    therapy, interventional radiology techniques, and isolated hepatic
    perfusion. We believe that Melphalan/HDS and CHEMOSAT represent a
    potentially important advancement in regional therapy for primary
    liver cancer and certain other cancers metastatic to the liver and
    are uniquely positioned to treat the entire liver either as a
    standalone therapy or as a complement to other therapies.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Our clinical development program for Melphalan/HDS is comprised of
    the FOCUS Clinical Trial for Patients with Hepatic Dominant Ocular
    Melanoma (the &amp;#x201C;FOCUS Trial&amp;#x201D;), a global registration
    clinical trial that is investigating objective response rate in
    mOM, and the ALIGN Trial, a global Phase 3 clinical trial for ICC
    (the &amp;#x201C;ALIGN Trial&amp;#x201D;). Our product also includes a
    registry for CHEMOSAT commercial cases performed in Europe and
    sponsorship of select Investigator Initiated Trials.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    While we currently utilize third parties to manufacture some
    components of our product, we also have our own manufacturing
    operations for certain components of our product and assemble and
    package our products in Queensbury, New York. See the discussion in
    Part 1, Item 1 under the caption &amp;#x201C;Manufacturing and Quality
    Assurance&amp;#x201D; above.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    We commercialize our product in Europe through alliances with third
    parties.&lt;/p&gt;

    The accompanying financial statements have been prepared on a going
    concern basis, which contemplates the realization of assets and the
    satisfaction of liabilities in the normal course of business. As
    shown in the accompanying financial statements during the year
    ended December&amp;#xA0;31, 2018, the Company incurred net losses of
    $19.2&amp;#xA0;million and used $14.7&amp;#xA0;million of cash for its
    operating activities. These factors among others raise substantial
    doubt about the Company&amp;#x2019;s ability to continue as a going
    concern for a reasonable period of time.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company&amp;#x2019;s existence is dependent upon management&amp;#x2019;s
    ability to obtain additional funding sources or to enter into
    strategic alliances. Adequate additional financing may not be
    available to us on acceptable terms, or at all. If the Company is
    unable to raise additional capital and/or enter into strategic
    alliances when needed or on attractive terms, it would be forced to
    delay, reduce or eliminate our research and development programs or
    any commercialization efforts. There can be no assurance that the
    Company&amp;#x2019;s efforts will result in the resolution of the
    Company&amp;#x2019;s liquidity needs. If Delcath is not able to continue
    as a going concern, it is likely that holders of its Common Stock
    will lose all of their investment. The accompanying consolidated
    financial statements do not include any adjustments that might
    result should the Company be unable to continue as a going
    concern.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company anticipates incurring additional losses until such
    time, if ever, that it can generate significant sales. At
    December&amp;#xA0;31, 2018, management believed that its capital
    resources were adequate to fund operations through March 2019.
    Additional working capital will be required to continue operations.
    Operations of the Company are subject to certain risks and
    uncertainties, including, among others, uncertainty of product
    development and clinical trial results; uncertainty regarding
    regulatory approval; technological uncertainty; uncertainty
    regarding patents and proprietary rights; comprehensive government
    regulations; limited commercial manufacturing, marketing or sales
    experience; and dependence on key personnel. See Note 15 of these
    notes to the Company&amp;#x2019;s audited consolidated financial
    statements relating to subsequent events.&lt;/p&gt;

    conform to generally accepted accounting principles in the United
    States of America (&amp;#x201C;GAAP&amp;#x201D;). The preparation of

    management to make assumptions and estimates that impact the
    amounts reported in the Company&amp;#x2019;s consolidated financial
    statements. The consolidated financial statements include the
    accounts of all entities controlled by Delcath. All significant
    inter-company accounts and transactions are eliminated.&lt;/p&gt;

    The Company considers investments with original maturities of three
    months or less at date of acquisition to be cash equivalents. The
    Company has deposits that exceed amounts insured by the Federal
    Deposit Insurance Corporation (&amp;#x201C;FDIC&amp;#x201D;), however, the
    Company does not consider this a significant concentration of

    In February 2010, the Company entered into an agreement to lease
    (Initial Lease) 8,629 square feet of office space at 810 Seventh
    Avenue, New York, NY with an option to expand an additional 8,629
    square feet. The term of the Initial Lease began in March, 2010. In
    September 2010, the Company exercised its option right under the
    Initial Lease and entered into an agreement to lease (Lease
    Amendment) an additional 8,629 square feet of office space. The
    term of the Lease Amendment began in January 2011 and will expire
    in March 2021. In addition, the Lease Amendment extends the term of
    the Initial Lease to March 2021. The Initial Lease and the Lease
    Amendment provide for annual rent of $1.0&amp;#xA0;million in 2015,
    $1.0&amp;#xA0;million in 2016, and $1.2&amp;#xA0;million in 2017-2020. As

    In August 2011, Delcath Systems Ltd. entered into an agreement of
    lease for an office and manufacturing facility located in the city
    of Galway, Ireland. This facility is approximately 19,200 square
    feet and is intended to be the location of Delcath&amp;#x2019;s European
    headquarters. The Lease is for a term of ten years, commencing
    August, 2011. The Lease provides for fixed annual lease amounts
    payable in advance in equal quarterly installments. The remaining
    annual lease amount is $0.2&amp;#xA0;million. Delcath Systems Ltd. is
    also required to pay for customary building operating expenses.
    Delcath Systems Ltd.&amp;#x2019;s payment obligations and performance of
    the Lease are guaranteed by Delcath. The Company has &lt;font style="WHITE-SPACE: nowrap"&gt;sub-leased&lt;/font&gt; a portion of this

    2016 (the &amp;#x201C;1633 Sublease) for approximately 6,877 square feet
    of office space at 1633 Broadway, New York, NY. The term began in

    In January 2019, the Company entered into an amendment (the
    &amp;#x201C;Park Road Lease Amendment&amp;#x201D;) to a lease agreement
    entered into in October 2018 (the &amp;#x201C;Park Road Lease&amp;#x201D;)
    for approximately 6,000 square feet of space located at
    &lt;font style="WHITE-SPACE: nowrap"&gt;95-97&lt;/font&gt; Park Road in
    Queensbury, New York. Under the terms of the Park Road Lease
    Amendment, the original two year term which began on

    As previously reported, on March&amp;#xA0;26, 2019, the Company
    commenced an action (the &amp;#x201C;Action&amp;#x201D;) in the Commercial
    Division of the Supreme Court for the State of New York, County of
    New York, styled as Delcath Systems, Inc., v. Iroquois Capital
    Investment Group LLC, Iroquois Master Fund Ltd., L1 Capital Global
    Opportunities Master Fund and First Fire Global Opportunities Fund
    LLC (Index No.&amp;#xA0;651749/2019). The Action seeks expedited
    equitable relief in the form of reformation and a declaratory
    judgement to remedy a scrivener&amp;#x2019;s error in the Series D
    Warrants issued in the Company&amp;#x2019;s February 2018 public
    offering such that those warrants do not contain a price and
    quantity ratchet upon a sale of Company securities at a price lower
    than the offering price in the February 2018 offering. The
    defendant, L1 Capital Global Opportunities Master Fund, settled
    with the Company by exchanging its Series D Warrants for Company
    Common Stock on a &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;one-for-one&lt;/font&gt;&lt;/font&gt; basis, which is the
    same ratio for which other investors in the February 2018 round
    exchanged their Series D Warrants in December 2018. The Company and
    the remaining defendants in the Action, Iroquois Capital Investment
    Group LLC, Iroquois Master Fund Ltd. and First Fire Global
    Opportunities Fund LLC, entered into a settlement agreement on
    April&amp;#xA0;18, 2019, the full text of which is annexed as Exhibit
    10.42 to our Annual Report on Form &lt;font style="WHITE-SPACE: nowrap"&gt;10-K,&lt;/font&gt; pursuant to which such
    defendants surrendered the Series D Warrants and waived all rights
    granted to them by or in connection with the Series D Warrants and
    all rights afforded to them to participate in the Company&amp;#x2019;s
    future Common Stock offerings. In consideration therefor, pursuant
    to the settlement agreement, (i)&amp;#xA0;the Company paid &lt;font style="WHITE-SPACE: nowrap"&gt;one-fifth&lt;/font&gt; of the reasonable fees and
    expenses of defendants&amp;#x2019; counsel incurred in connection with
    the Action and negotiation of the settlement agreement, the total
    of which shall not exceed $50,000 (the &amp;#x201C;Settlement
    Fees&amp;#x201D;) and (ii)&amp;#xA0;subject to the Company securing and
    closing certain contemplated financing, the Company agreed to pay
    to the defendants $400,000 and the remaining Settlement Fees.&lt;/p&gt;

    As previously reported, on July&amp;#xA0;27, 2018, Hudson Bay Master
    Fund Ltd. filed a summons and complaint against the Company in the
    New York State Supreme Court, New York County alleging breaches by
    the Company of Hudson Bay&amp;#x2019;s rights of participation in future
    Company offerings granted in the September 2017 Securities Purchase
    Agreement between the Company and Hudson Bay and in the February
    2018 Securities Purchase Agreement among, inter alia, the Company
    and Hudson Bay. In terms of relief sought, Hudson Bay claimed both
    monetary damages (which it claims to be in excess of $1 million)
    and specific performance. The Company denied any liability with
    respect to the claims set forth in the lawsuit. As previously
    reported, on January&amp;#xA0;4, 2019, the Company was notified by its
    litigation counsel that on December&amp;#xA0;28, 2018, the Suit was
    dismissed with prejudice by the filing of a Stipulation for
    Discontinuance in the New York State Supreme Court, New York
    County.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On May&amp;#xA0;9, 2018, the Company received a Demand Letter from a
    vendor for an outstanding balance owed at that time of
    $2.1&amp;#xA0;million. The Company has worked with the vendor since
    that time to establish a payment plan for the balance owed.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 18px"&gt;

    Under the terms of the lease agreement for office space at 810
    Seventh Avenue, New York, NY, the Company is required to maintain a
    letter of credit in the amount of $0.9&amp;#xA0;million which will
    expire in February 2021 if not renewed by the Company. Under the
    terms of a &lt;font style="WHITE-SPACE: nowrap"&gt;sub-lease&lt;/font&gt;
    agreement for office space at 1633 Broadway, New York, NY, the
    Company is required to maintain a letter of credit in the amount of
    $0.1&amp;#xA0;million which will expire with the sublease in February
    2021.&lt;/p&gt;

    The Company accounts for derivative instruments in accordance with
    Accounting Standards Codification (&amp;#x201C;ASC&amp;#x201D;) 815,
    Derivatives and Hedging, which establishes accounting and reporting
    standards for derivative instruments and hedging activities,
    including certain derivative instruments embedded in other
    financial instruments or contracts and requires recognition of all
    derivatives on the balance sheet at fair value, regardless of the
    hedging relationship designation. Accounting for changes in the
    fair value of the derivative instruments depends on whether the
    derivatives qualify as hedge relationships and the types of
    relationships designated are based on the exposures hedged. At
    December&amp;#xA0;31, 2018 and 2017, the Company did not have any
    derivative instruments that were designated as hedges.&lt;/p&gt;

    Basic net loss per share is determined by dividing net loss by the
    weighted average shares of Common Stock outstanding during the
    period. Diluted net loss per share is determined by dividing net
    loss by diluted weighted average shares outstanding. Diluted
    weighted average shares reflects the dilutive effect, if any, of
    potentially dilutive common shares, such as stock options and
    warrants calculated using the treasury stock method. In periods
    with reported net operating losses, all stock options, unvested
    restricted stock and warrants are deemed anti-dilutive such that
    basic net loss per share and diluted net loss per share are
    equal.&lt;/p&gt;

    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company adheres to ASC 820, Fair Value Measurement, which
    defines fair value, establishes a framework for measuring fair
    value, and expands disclosures about fair value measurements. ASC
    820 applies to reported balances that are required or permitted to
    be measured at fair value under existing accounting pronouncements;
    accordingly, the standard does not require any new fair value
    measurements of reported balances.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    ASC 820 emphasizes that fair value is a market-based measurement,
    not an entity-specific measurement.&amp;#xA0;Therefore, a fair value
    measurement should be determined based on the assumptions that
    market participants would use in pricing the asset or
    liability.&amp;#xA0;As a basis for considering market participant
    assumptions in fair value measurements, ASC 820 establishes a fair
    value hierarchy that distinguishes between market participant
    assumptions based on market data obtained from sources independent
    of the reporting entity (observable inputs that are classified
    within Levels 1 and 2 of the hierarchy) and the reporting
    entity&amp;#x2019;s own assumptions about market participant assumptions
    (unobservable inputs classified within Level&amp;#xA0;3 of the
    hierarchy).&lt;/p&gt;

    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt" align="left"&gt;Level&amp;#xA0;1 inputs utilize quoted prices (unadjusted)

    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt" align="left"&gt;Level&amp;#xA0;2 inputs are inputs other than quoted
    prices included in Level&amp;#xA0;1 that are observable for the asset
    or liability, either directly or indirectly. Level&amp;#xA0;2 inputs
    may include quoted prices for similar assets and liabilities in
    active markets, as well as inputs that are observable for the asset
    or liability (other than quoted prices), such as interest rates,
    foreign exchange rates, and yield curves that are observable at
    commonly quoted intervals.&lt;/p&gt;
    &lt;/td&gt;
    &lt;/tr&gt;
    &lt;/table&gt;

    asset or liability, which is typically based on an entity&amp;#x2019;s
    own assumptions, as there is little, if any, related market
    activity.&lt;/p&gt;
    &lt;/td&gt;
    &lt;/tr&gt;

    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In instances where the determination of the fair value measurement
    is based on inputs from different levels of the fair value
    hierarchy, the level in the fair value hierarchy within which the
    entire fair value measurement falls is based on the lowest level
    input that is significant to the fair value measurement in its
    entirety. The Company&amp;#x2019;s assessment of the significance of a
    particular input to the fair value measurement in its entirety
    requires judgment and considers factors specific to the asset or
    liability.&lt;/p&gt;

    Transactions that are denominated in a foreign currency are
    remeasured into the functional currency at the current exchange
    rate on the date of the transaction. Any foreign
    currency-denominated monetary assets and liabilities are
    subsequently remeasured at current exchange rates, with gains or
    losses recognized as foreign exchange (losses)/gains in the
    statements of operations.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The assets and liabilities of the Company&amp;#x2019;s international
    subsidiaries are translated from their functional currencies into
    United States dollars at exchange rates prevailing at the balance
    sheet date. The majority of the foreign subsidiaries revenues and
    operating expenses are denominated in Euros. The reporting currency
    for the Company is the United States Dollar (&amp;#x201C;USD&amp;#x201D;).
    Average rates of exchange during the period are used to translate
    the statement of operations, while historical rates of exchange are
    used to translate any equity transactions.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Translation adjustments arising on consolidation due to differences
    between average rates and balance sheet rates, as well as
    unrealized foreign exchange gains or losses arising from
    translation of intercompany loans that are of a
    long-term-investment nature, are recorded in other comprehensive
    income.&lt;/p&gt;

    As of December&amp;#xA0;31, 2018 and 2017 the Company had net operating
    loss carryforwards for U.S. federal income tax purposes of
    approximately $230.0&amp;#xA0;million and $211.3&amp;#xA0;million
    respectively. A significant portion of the federal amount is
    subject to an annual limitation as low as $27,500 as a result of
    changes in the Company&amp;#x2019;s ownership in May 2003, November
    2016, and multiple dates throughout 2017 and 2018, as defined by
    Federal Internal Revenue Code Section&amp;#xA0;382 and the related
    income tax regulations. As a result of the limitations caused by
    the May 2003, November 2016 and multiple 2017 and 2018 ownership
    changes, approximately $208.1&amp;#xA0;million of the total net
    operating loss carryforwards is expected to expire unutilized and
    will be unavailable to offset future federal taxable income.
    Approximately $21.9&amp;#xA0;million of net operating loss
    carryforwards remains available to offset future federal taxable
    income, of which $1.7&amp;#xA0;million will expire between 2019 and
    2037 and $20.2&amp;#xA0;million will have an unlimited carryforward
    period as a result of the Tax Cuts and Jobs Act.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In addition, the Company&amp;#x2019;s state net operating losses are
    also subject to annual limitations that generally follow the
    federal Section&amp;#xA0;382 provisions (with the exception of
    Connecticut), adjusted for each state&amp;#x2019;s respective income
    apportionment percentages. As of December&amp;#xA0;31, 2018 and 2017,
    the Company had net operating loss carryforwards for state and city
    income tax purposes between approximately $27.3&amp;#xA0;million and
    $167.3&amp;#xA0;million and between approximately $27.3&amp;#xA0;million
    and $150.3&amp;#xA0;million, respectively, which expire through 2038.
    As a result of the 382 limitations, approximately
    $157.2&amp;#xA0;million and $141.5 million of New York State and New
    York City net operating losses are expected to expire unutilized
    and will be unavailable to offset future taxable income.
    Approximately $10.1&amp;#xA0;million and $10.1&amp;#xA0;million of net
    operating loss carryforwards, respectively, will be available to
    offset future state and city taxable income. As of
    December&amp;#xA0;31, 2018 and 2017 the Company had a net operating
    loss carryforward for foreign income tax purposes of
    $25.2&amp;#xA0;million and $25.0&amp;#xA0;million, respectively, which have
    indefinite carryforward periods. As of December&amp;#xA0;31, 2018 and
    2017, the Company had federal research and development tax credit
    carryforwards of approximately $5.0&amp;#xA0;million and
    $4.3&amp;#xA0;million respectively, which expire through 2038. As a
    result of the section 382 limitations, all but $0.2&amp;#xA0;million of
    the tax credit carryforwards is expected to expire unutilized.&lt;/p&gt;

    Management has established a 100% valuation allowance against the
    deferred tax assets as management does not believe it is more
    likely than not that these assets will be realized. The
    Company&amp;#x2019;s valuation allowance decreased by approximately
    $5.4&amp;#xA0;million and decreased by $1.1&amp;#xA0;million in 2018 and
    2017, respectively. The change in valuation allowance is as
    follows:&lt;/p&gt;

    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On December&amp;#xA0;22, 2017, the United States enacted the Tax Cuts
    and Jobs Act (the &amp;#x201C;Act&amp;#x201D;). The Act, which is also
    commonly referred to as &amp;#x201C;U.S. tax reform&amp;#x201D;,
    significantly changes U.S. corporate income tax laws by, among
    other provisions, reducing the maximum U.S. corporate income tax
    rate from 35% to 21% starting in 2018. During the year ended
    December&amp;#xA0;31, 2017, the Company reduced deferred tax assets by
    a provisional amount of $143,500, offset by a corresponding
    reduction to its valuation allowance, as a result of the
    &lt;font style="WHITE-SPACE: nowrap"&gt;re-measurement&lt;/font&gt; of deferred
    tax assets and liabilities from its 34% effective rate under
    existing law to the new lower statutory rate of 21%. The Company
    finalized its accounting of the effects of tax reform in 2018,
    which resulted in insignificant adjustments.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Act also requires a mandatory &lt;font style="WHITE-SPACE: nowrap"&gt;one-time&lt;/font&gt; inclusion of the deferred
    foreign income of controlled foreign corporations. The &lt;font style="WHITE-SPACE: nowrap"&gt;one-time&lt;/font&gt; transition tax is based on
    Delcath&amp;#x2019;s total post-1986 earnings and profits (E&amp;amp;P) for
    which the Company has previously deferred from U.S. income taxes.
    During the year ended December&amp;#xA0;31, 2017, the Company&amp;#x2019;s
    reasonable estimate resulted in no provisional amount for the
    &lt;font style="WHITE-SPACE: nowrap"&gt;one-time&lt;/font&gt; transition tax
    liability, as the Company&amp;#x2019;s international subsidiaries are
    expected to have a cumulative deficit in E&amp;amp;P. As the
    Company&amp;#x2019;s international subsidiaries have a cumulative
    deficit in earnings and profits, the Company did not anticipate
    being affected by the mandatory inclusion provisions of the Act.
    The Company finalized its calculation of the total post-1986
    foreign E&amp;amp;P (including deficits) for these foreign subsidiaries
    during 2018 and was not impacted by the mandatory inclusion
    provisions of the Act.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On December, 22, 2017, Staff Accounting Bulletin 118 was issued due
    to the complexities involved in accounting for the recently enacted
    Act. SAB 118 requires the Company to include in its financial
    statements a reasonable estimate of the impact of the Act on
    earnings to the extent such estimate has been determined.
    Accordingly, the U.S. provision for income tax for
    December&amp;#xA0;31, 2017 was based on the reasonable estimate
    guidance provided by SAB 118. The Company finalized the impact from
    the Act and recorded insignificant adjustments.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company complies with the provisions of ASC &lt;font style="WHITE-SPACE: nowrap"&gt;740-10,&lt;/font&gt; Income Taxes, in accounting
    for its uncertain tax positions. ASC &lt;font style="WHITE-SPACE: nowrap"&gt;740-10&lt;/font&gt; addresses the determination of
    whether tax benefits claimed or expected to be claimed on a tax
    return should be recorded in the financial statements. Under ASC
    &lt;font style="WHITE-SPACE: nowrap"&gt;740-10,&lt;/font&gt; the Company may
    recognize the tax benefit from an uncertain tax position only if it
    is more likely than not that the tax position will be sustained on
    examination by the taxing authorities, based on the technical
    merits of the position. The Company has determined that the Company
    has no significant uncertain tax positions requiring recognition
    under ASC &lt;font style="WHITE-SPACE: nowrap"&gt;740-10&lt;/font&gt; and
    therefore has not included a tabular rollforward of unrecognized
    tax benefits. As there are no uncertain tax positions recognized,
    interest and penalties have not been accrued.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company is subject to income tax in the U.S., as well as
    various state and international jurisdictions. The Company has not
    been audited by any state tax authorities in connection with income
    taxes. The Company has not been audited by international tax
    authorities or any states in connection with income taxes. The
    Company&amp;#x2019;s New York State tax returns have been subject to
    annual desk reviews which have resulted in insignificant
    adjustments to the related franchise tax liabilities and credits.
    The Company is no longer subject to federal and state examination
    for tax years ending prior to December&amp;#xA0;31, 2015; tax years
    ending December&amp;#xA0;31, 2015 through December&amp;#xA0;31, 2018 remain
    open to examination. The Republic of Ireland is the Company&amp;#x2019;s
    only significant foreign jurisdiction. The Company is no longer
    subject to Ireland tax examination for tax years ending prior to
    December&amp;#xA0;31, 2014 (as Ireland has not initiated an audit of
    2013 as of December&amp;#xA0;31, 2018); tax years ending
    December&amp;#xA0;31, 2014 through December&amp;#xA0;31, 2018 remain open
    to examination. However, the Company&amp;#x2019;s tax years
    December&amp;#xA0;31, 1998 through December&amp;#xA0;31, 2018 generally
    remain open to adjustment for all federal, state and foreign tax
    matters until its net operating loss and tax credit carryforwards
    are utilized or expire prior to utilization, and the applicable
    statutes of limitation have expired in the utilization year. The
    federal and state tax authorities can generally reduce a net
    operating loss (but not create taxable income) for a period outside
    the statute of limitations in order to determine the correct amount
    of net operating loss which may be allowed as a deduction against
    income for a period within the statute of limitations.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Delcath recognizes interest accrued related to unrecognized tax
    benefits and penalties, if incurred, as a component of income tax
    expense.&lt;/p&gt;

    The Company accounts for income taxes following the asset and
    liability method in accordance with the ASC 740, Income Taxes.
    Under such method, deferred tax assets and liabilities are
    recognized for the future tax consequences attributable to
    differences between the consolidated financial statement carrying
    amounts of existing assets and liabilities and their respective tax
    bases. The Company applies the accounting guidance issued to
    address the accounting for uncertain tax positions. This guidance
    clarifies the accounting for income taxes, by prescribing a minimum
    recognition threshold a tax position is required to meet before
    being recognized in the financial statements as well as provides
    guidance on derecognition, measurement, classification, interest
    and penalties, accounting in interim periods, disclosure and
    transition. The Company classifies interest and penalty expense
    related to uncertain tax positions as a component of income tax
    expense. Deferred tax assets and liabilities are measured using
    enacted tax rates expected to apply to taxable income in the years
    that the asset is expected to be recovered or the liability
    settled. A valuation allowance is provided when it is more likely
    than not that some portion or all of a deferred tax asset will not
    be realized. The ultimate realization of deferred tax assets
    depends on the generation of future taxable income during the
    period in which related temporary differences become deductible.
    The Company considers the scheduled reversal of deferred tax

    In May 2014, the Financial Accounting Standards Board
    (&amp;#x201C;FASB&amp;#x201D;) issued Accounting Standards Update
    (&amp;#x201C;ASU&amp;#x201D;) &lt;font style="WHITE-SPACE: nowrap"&gt;2014-09,&lt;/font&gt; Revenue from Contracts with
    Customers, that updates the principles for recognizing revenue. The
    core principle of the guidance is that an entity should recognize
    revenue to depict the transfer of promised goods or services to
    customers in an amount that reflects the consideration to which the
    entity expects to be entitled in exchange for those goods or
    services. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2014-09&lt;/font&gt; also
    amends the required disclosures of the nature, amount, timing and
    uncertainty of revenue and cash flows arising from contracts with
    customers. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2014-09&lt;/font&gt; is
    effective for the Company beginning in its fiscal year 2018, and
    may be applied retrospectively to all prior periods presented or
    through a cumulative adjustment to the opening retained earnings
    balance in the year of adoption. The Company has adopted this
    guidance.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In June 2016, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-15,&lt;/font&gt; Statement of Cash Flows
    (Topic 230), which is intended to reduce diversity in practice in
    how certain transactions are classified in the statement of cash
    flows. The ASU is effective for public companies for fiscal years
    beginning after December&amp;#xA0;15, 2017, and interim periods within
    those fiscal years. Early adoption was permitted, including interim
    periods within those fiscal years provided that those electing
    early adoption must adopt all of the amendments in the same period.
    The guidance requires application using a retrospective transition
    method. The Company has adopted this guidance.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In October 2016, the FASB issues ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-16&lt;/font&gt; which simplifies the income
    tax consequences of intra-entity transfers other than inventory.
    Prior to ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-16,&lt;/font&gt; GAAL
    prohibited the recognition of current and deferred income taxes for
    intra-entity asset transfers until the asset has been sold to an
    outside party. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-16&lt;/font&gt;
    eliminates this prohibition for intra-entity transfers of assets
    other than inventory but retains the prohibition for intra-entity
    transfers of inventory. This standard is effective go r public
    entities for fiscal years beginning after December&amp;#xA0;15, 2017.
    The Company has adopted this guidance. The adoption did not have a
    material impact on the Company&amp;#x2019;s consolidated financial
    statements.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In November 2016, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-18,&lt;/font&gt; Statement of Cash Flows
    (Topic 230): Restricted Cash, which requires that the statement of
    cash flows explain the change during the period in the total of
    cash, cash equivalents, and amounts generally described as
    restricted cash or restricted cash equivalents. Entities are also
    required to reconcile such total to amounts on the balance sheet
    and disclose the nature of the restrictions. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-18&lt;/font&gt; is effective for fiscal years
    beginning after December&amp;#xA0;15, 2017 and interim periods within
    those fiscal years, and early adoption was permitted. The Company
    adopted this standard.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 18px"&gt;
    &amp;#xA0;&lt;/p&gt;

    &lt;b&gt;&lt;i&gt;SEC Disclosure Update and Simplification&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In August 2018, the SEC adopted the final rule under SEC Release
    &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;33-10532,&lt;/font&gt;
    Disclosure Update and Simplification, amending certain disclosure
    requirements that were redundant, duplicative, overlapping,
    outdated or superseded. In addition, the amendments expanded the
    disclosure requirements on the analysis of stockholders&amp;#x2019;
    equity for interim financial statements. Under the amendments, an
    analysis of changes in each caption of stockholders&amp;#x2019; equity
    presented in the balance sheet must be provided in a note or
    separate statement. The analysis should present a reconciliation of
    the beginning balance to the ending balance of each period for
    which a statement of comprehensive income is required to be filed.
    This final rule was effective on November&amp;#xA0;5, 2018. The
    adoption did not have a material impact on the Company&amp;#x2019;s
    consolidated financial statements.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
    &lt;b&gt;&lt;i&gt;Recent Accounting Standards to be Adopted&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In February 2016, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-02,&lt;/font&gt; Leases (Topic 842),
    superseding ASC Topic 840, Leases. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-02&lt;/font&gt; requires lessees to recognize
    a &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;right-of-use&lt;/font&gt;&lt;/font&gt; asset and a lease
    liability on their balance sheets for all the leases with terms
    greater than twelve months. Based on certain criteria, leases will
    be classified as either financing or operating, with classification
    affecting the pattern of expense recognition in the income
    statement. For leases with a term of twelve months or less, a
    lessee is permitted to make an accounting policy election by class
    of underlying asset not to recognize lease assets and lease
    liabilities. If a lessee makes this election, it should recognize
    lease expense for such leases generally on a straight-line basis
    over the lease term. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-02&lt;/font&gt; is effective for fiscal years
    beginning after December&amp;#xA0;15, 2018, and interim periods within
    those years, with early adoption permitted. In transition, lessees
    and lessors are required to recognize and measure leases at the
    beginning of the earliest period presented using a modified
    retrospective approach. In July 2018, the FASB issued ASU
    &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2018-11,&lt;/font&gt; Leases
    (Topic 842): Targeted Improvements that allows entities to apply
    the provisions of the new standard at the effective date (e.g.
    January&amp;#xA0;1, 2019), as opposed to the earliest period presented
    under the modified retrospective transition approach (January 1,
    2017) and recognize a cumulative-effect adjustment to the opening
    balance of retained earnings in the period of adoption. The
    modified retrospective approach includes a number of optional
    practical expedients primarily focused on leases that commenced
    before the effective date of Topic 842, including continuing to
    account for leases that commence before the effective date in
    accordance with previous guidance, unless the lease is modified.
    The Company is currently evaluating the effect the guidance will
    have on our audited consolidated financial statements.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In July 2017, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2017-11,&lt;/font&gt; Earnings Per Share (Topic
    260) Distinguishing Liabilities from Equity (Topic 480) Derivatives
    and Hedging (Topic 815). This guidance&amp;#xA0;was intended to reduce
    the complexity associated with the issuer&amp;#x2019;s accounting for
    certain financial instruments with characteristics of liabilities
    and equity. Specifically, the Board determined that a down round
    feature would no longer cause a freestanding equity-linked
    financial instrument (or an embedded conversion option) to be
    accounted for as a derivative liability at fair value with changes
    in fair value recognized in current earnings. In addition, the
    Board &lt;font style="WHITE-SPACE: nowrap"&gt;re-characterized&lt;/font&gt; the
    indefinite deferral of certain provisions of Topic 480 to a scope
    exception. The &lt;font style="WHITE-SPACE: nowrap"&gt;re-characterization&lt;/font&gt; has no accounting
    effect. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2017-11&lt;/font&gt; is
    effective for public entities for fiscal years beginning after
    December&amp;#xA0;15, 2018. The Company intends to adopt this standard
    on January&amp;#xA0;1, 2019 and is evaluating the effects, if any, that
    the adoption of this guidance will have on the Company&amp;#x2019;s
    consolidated financial statements.&lt;/p&gt;

    Property, plant and equipment are recorded at cost, less
    accumulated depreciation. The Company provides for depreciation on
    a straight line basis over the estimated useful lives of the assets
    which range from three to seven years. Leasehold improvements will
    be amortized over the shorter of the lease term or the estimated
    useful life of the related assets when they are placed into
    service. The Company evaluates property, plant and equipment for
    impairment periodically to determine if changes in circumstances or
    the occurrence of events suggest the carrying value of the asset or
    asset group may not be recoverable. Maintenance and repairs are
    charged to operations as incurred. Expenditures which substantially
    increase the useful lives of the related assets are
    capitalized.&lt;/p&gt;

    Revenue is generated from proprietary and partnered product sales
    and license and royalty arrangements. Revenue is recognized when or
    as we transfer control of the promised goods or services to our
    customers in an amount that reflects the consideration to which we
    expect to be entitled to in exchange for those goods or services.
    When obligations or contingencies remain after the products are
    shipped, such as training and certifying the treatment centers,
    revenue is deferred until the obligations or contingencies are
    satisfied.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    We may enter into contracts with partners that contain multiple
    elements such as licensing, development, manufacturing and
    commercialization components. These arrangements are often complex
    and we may receive various types of consideration over the life of
    the arrangement, including: &lt;font style="WHITE-SPACE: nowrap"&gt;up-front&lt;/font&gt; fees, reimbursements for
    research and development services, milestone payments, payments on
    product shipments, margin sharing arrangements, license fees and
    royalties.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Our results of operations for reporting periods beginning on or
    after January&amp;#xA0;1, 2018 are presented under ASC 606, Revenue
    from Contracts with Customers, while prior period amounts, as
    reported, are not adjusted. The effects of the adoption of the new
    standard in 2018 were not material to our consolidated financial
    statements. In assessing our revenue arrangements in accordance
    with ASC 606, Revenue from Contracts with Customers, we must
    identify the contract, determine the transaction price including an
    estimation of any variable consideration we expect to receive in
    connection with the contract, identify the promises of goods or
    services to the customer and each distinct performance obligation,
    allocate the transaction price to each of the performance
    obligations, and recognize revenue when or as the performance
    obligations are satisfied. Each of these steps in the revenue
    recognition process requires management to make judgements and/or
    estimates. The most significant judgements and estimates involve
    the determination of variable consideration to be included in the
    transaction price. Variable consideration is recognized at an
    amount we believe is not subject to significant reversal and is
    adjusted at each reporting period if the most likely amount of
    expected consideration changes or becomes fixed. We believe this
    provides a reasonable basis for recognizing revenue, however,
    actual results could differ from estimates and significant changes
    in estimates could impact our results of operations in future
    periods.&lt;/p&gt;

    entered into two &lt;font style="WHITE-SPACE: nowrap"&gt;sub-leases&lt;/font&gt; for office space at its 810

    location (&amp;#x201C;Suite 3500&amp;#x201D;), resulting in a lease

    The Company bases its estimates and judgments on historical
    experience and on various other assumptions that it believes are
    reasonable under the circumstances. The amounts of assets and
    liabilities reported in the Company&amp;#x2019;s consolidated balance
    sheets and the amount of revenues and expenses reported for each of
    the periods presented are affected by estimates and assumptions,
    which are used for, but not limited to, the accounting for
    derivative instrument liabilities, stock-based compensation,
    valuation of inventory, impairment of long-lived assets, income
    taxes and operating expense accruals. Such assumptions and
    estimates are subject to change in the future as additional
    information becomes available or as circumstances are modified.
    Actual results could differ from these estimates.&lt;/p&gt;

    &lt;b&gt;&lt;i&gt;Cash Equivalents and Concentrations of Credit

    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company considers investments with original maturities of three
    months or less at date of acquisition to be cash equivalents. The
    Company has deposits that exceed amounts insured by the Federal
    Deposit Insurance Corporation (&amp;#x201C;FDIC&amp;#x201D;), however, the
    Company does not consider this a significant concentration of
    credit risk based on the strength of the financial institution.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
    &lt;b&gt;&lt;i&gt;Restricted Cash&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Cash and cash equivalents that are restricted as to withdrawal or
    use under the terms of certain contractual agreements are recorded
    as restricted cash on the accompanying consolidated balance
    sheets.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
    &lt;b&gt;&lt;i&gt;Accounts Receivable&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Accounts receivable, principally trade, are generally due within 30
    days and are stated at amounts due from customers. Collections and
    payments from customers are monitored and a provision for estimated
    credit losses may be created based upon historical experience and
    specific customer collection issues that may be identified.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 18px"&gt;

    Inventories are valued at the lower of cost or market value using
    the &lt;font style="WHITE-SPACE: nowrap"&gt;first-in,&lt;/font&gt; &lt;font style="WHITE-SPACE: nowrap"&gt;first-out&lt;/font&gt; method.&amp;#xA0;The reported
    net value of inventory includes finished saleable products,
    &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;work-in-process,&lt;/font&gt;&lt;/font&gt; and raw
    materials that will be sold or used in future periods.&amp;#xA0;The
    Company reserves for expired, obsolete, and slow-moving
    inventory.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;

    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Property, plant and equipment are recorded at cost, less
    accumulated depreciation. The Company provides for depreciation on
    a straight line basis over the estimated useful lives of the assets
    which range from three to seven years. Leasehold improvements will
    be amortized over the shorter of the lease term or the estimated
    useful life of the related assets when they are placed into
    service. The Company evaluates property, plant and equipment for
    impairment periodically to determine if changes in circumstances or
    the occurrence of events suggest the carrying value of the asset or
    asset group may not be recoverable. Maintenance and repairs are
    charged to operations as incurred. Expenditures which substantially
    increase the useful lives of the related assets are
    capitalized.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
    &lt;b&gt;&lt;i&gt;Derivative Instrument Liability&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company accounts for derivative instruments in accordance with
    Accounting Standards Codification (&amp;#x201C;ASC&amp;#x201D;) 815,
    Derivatives and Hedging, which establishes accounting and reporting
    standards for derivative instruments and hedging activities,
    including certain derivative instruments embedded in other
    financial instruments or contracts and requires recognition of all
    derivatives on the balance sheet at fair value, regardless of the
    hedging relationship designation. Accounting for changes in the
    fair value of the derivative instruments depends on whether the
    derivatives qualify as hedge relationships and the types of
    relationships designated are based on the exposures hedged. At
    December&amp;#xA0;31, 2018 and 2017, the Company did not have any
    derivative instruments that were designated as hedges.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
    &lt;b&gt;&lt;i&gt;Fair Value Measurements&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company adheres to ASC 820, Fair Value Measurement, which
    defines fair value, establishes a framework for measuring fair
    value, and expands disclosures about fair value measurements. ASC
    820 applies to reported balances that are required or permitted to
    be measured at fair value under existing accounting pronouncements;
    accordingly, the standard does not require any new fair value
    measurements of reported balances.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    ASC 820 emphasizes that fair value is a market-based measurement,
    not an entity-specific measurement.&amp;#xA0;Therefore, a fair value
    measurement should be determined based on the assumptions that
    market participants would use in pricing the asset or
    liability.&amp;#xA0;As a basis for considering market participant
    assumptions in fair value measurements, ASC 820 establishes a fair
    value hierarchy that distinguishes between market participant
    assumptions based on market data obtained from sources independent
    of the reporting entity (observable inputs that are classified
    within Levels 1 and 2 of the hierarchy) and the reporting
    entity&amp;#x2019;s own assumptions about market participant assumptions
    (unobservable inputs classified within Level&amp;#xA0;3 of the
    hierarchy).&lt;/p&gt;

    In instances where the determination of the fair value measurement
    is based on inputs from different levels of the fair value
    hierarchy, the level in the fair value hierarchy within which the
    entire fair value measurement falls is based on the lowest level
    input that is significant to the fair value measurement in its
    entirety. The Company&amp;#x2019;s assessment of the significance of a
    particular input to the fair value measurement in its entirety
    requires judgment and considers factors specific to the asset or
    liability.&lt;/p&gt;

    Revenue is generated from proprietary and partnered product sales
    and license and royalty arrangements. Revenue is recognized when or
    as we transfer control of the promised goods or services to our
    customers in an amount that reflects the consideration to which we
    expect to be entitled to in exchange for those goods or services.
    When obligations or contingencies remain after the products are
    shipped, such as training and certifying the treatment centers,
    revenue is deferred until the obligations or contingencies are
    satisfied.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    We may enter into contracts with partners that contain multiple
    elements such as licensing, development, manufacturing and
    commercialization components. These arrangements are often complex
    and we may receive various types of consideration over the life of
    the arrangement, including: &lt;font style="WHITE-SPACE: nowrap"&gt;up-front&lt;/font&gt; fees, reimbursements for
    research and development services, milestone payments, payments on
    product shipments, margin sharing arrangements, license fees and
    royalties.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Our results of operations for reporting periods beginning on or
    after January&amp;#xA0;1, 2018 are presented under ASC 606, Revenue
    from Contracts with Customers, while prior period amounts, as
    reported, are not adjusted. The effects of the adoption of the new
    standard in 2018 were not material to our consolidated financial
    statements. In assessing our revenue arrangements in accordance
    with ASC 606, Revenue from Contracts with Customers, we must
    identify the contract, determine the transaction price including an
    estimation of any variable consideration we expect to receive in
    connection with the contract, identify the promises of goods or
    services to the customer and each distinct performance obligation,
    allocate the transaction price to each of the performance
    obligations, and recognize revenue when or as the performance
    obligations are satisfied. Each of these steps in the revenue
    recognition process requires management to make judgements and/or
    estimates. The most significant judgements and estimates involve
    the determination of variable consideration to be included in the
    transaction price. Variable consideration is recognized at an
    amount we believe is not subject to significant reversal and is
    adjusted at each reporting period if the most likely amount of
    expected consideration changes or becomes fixed. We believe this
    provides a reasonable basis for recognizing revenue, however,
    actual results could differ from estimates and significant changes
    in estimates could impact our results of operations in future
    periods.&lt;/p&gt;

    License fees and milestones received in exchange for the grant of a
    license for the commercialization of CHEMOSAT are generally
    recognized over the development period, as the license is
    considered distinct from the delivery of product. Milestone
    payments that are contingent upon the occurrence of future events,
    are evaluated and recorded at the most likely amount, and to the
    extent that it is probable that a significant reversal will not
    occur when the associated uncertainty is resolved.&lt;/p&gt;

    The Company accounts for its share-based compensation in accordance
    with the provisions of ASC 718, Stock-Based Compensation, which
    establishes accounting for equity instruments exchanged for
    employee services and ASC &lt;font style="WHITE-SPACE: nowrap"&gt;505-50,&lt;/font&gt; Equity-Based Payments to
    &lt;font style="WHITE-SPACE: nowrap"&gt;Non-Employees,&lt;/font&gt; which
    establishes accounting for equity-based payments to &lt;font style="WHITE-SPACE: nowrap"&gt;non-employees.&amp;#xA0;Under&lt;/font&gt; the
    provisions of ASC 718, share-based compensation is measured at the
    grant date, based upon the fair value of the award, and is
    recognized as an expense over the option holders&amp;#x2019; requisite
    service period (generally the vesting period of the equity grant).
    The Company is required to record compensation cost for all
    share-based payments granted to employees based upon the grant date
    fair value, estimated in accordance with the provisions of ASC 718.
    Under the provisions of ASC &lt;font style="WHITE-SPACE: nowrap"&gt;505-50,&lt;/font&gt; measurement of compensation
    cost related to common shares issued to &lt;font style="WHITE-SPACE: nowrap"&gt;non-employees&lt;/font&gt; for services is based on
    the value of the services provided or the fair value of the shares
    issued. The measurement of &lt;font style="WHITE-SPACE: nowrap"&gt;non-employee&lt;/font&gt; stock-based compensation
    is subject to periodic adjustment as the underlying equity
    instrument vests. The Company expenses its share-based compensation
    for share-based payments granted under the accelerated method,
    which treats each vesting tranche as if it were an individual
    grant.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company periodically grants stock options for a fixed number of
    shares of Common Stock to its employees, directors and &lt;font style="WHITE-SPACE: nowrap"&gt;non-employee&lt;/font&gt; contractors, with an
    exercise price greater than or equal to the fair market value of
    Delcath&amp;#x2019;s Common Stock at the date of the grant.&amp;#xA0;The
    Company estimates the fair value of stock options using an option
    pricing model.&amp;#xA0;Key inputs used to estimate the fair value of
    stock options include the exercise price of the award, the expected
    post-vesting option life, the expected volatility of
    Delcath&amp;#x2019;s stock over the option&amp;#x2019;s expected term, the
    risk-free interest rate over the option&amp;#x2019;s expected term, and
    Delcath&amp;#x2019;s expected annual dividend yield.&amp;#xA0;Estimates of
    fair value are not intended to predict actual future events or the
    value ultimately realized by persons who receive equity awards.&lt;/p&gt;

    &lt;b&gt;&lt;i&gt;Income Taxes&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company accounts for income taxes following the asset and
    liability method in accordance with the ASC 740, Income Taxes.
    Under such method, deferred tax assets and liabilities are
    recognized for the future tax consequences attributable to
    differences between the consolidated financial statement carrying
    amounts of existing assets and liabilities and their respective tax
    bases. The Company applies the accounting guidance issued to
    address the accounting for uncertain tax positions. This guidance
    clarifies the accounting for income taxes, by prescribing a minimum
    recognition threshold a tax position is required to meet before
    being recognized in the financial statements as well as provides
    guidance on derecognition, measurement, classification, interest
    and penalties, accounting in interim periods, disclosure and
    transition. The Company classifies interest and penalty expense
    related to uncertain tax positions as a component of income tax
    expense. Deferred tax assets and liabilities are measured using
    enacted tax rates expected to apply to taxable income in the years
    that the asset is expected to be recovered or the liability
    settled. A valuation allowance is provided when it is more likely
    than not that some portion or all of a deferred tax asset will not
    be realized. The ultimate realization of deferred tax assets
    depends on the generation of future taxable income during the
    period in which related temporary differences become deductible.
    The Company considers the scheduled reversal of deferred tax
    liabilities, projected future taxable income and tax planning
    strategies in its assessment of a valuation allowance. See Note 14
    for additional information.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 18px"&gt;

    &lt;b&gt;&lt;i&gt;Net Loss per Common Share&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Basic net loss per share is determined by dividing net loss by the
    weighted average shares of Common Stock outstanding during the
    period. Diluted net loss per share is determined by dividing net
    loss by diluted weighted average shares outstanding. Diluted
    weighted average shares reflects the dilutive effect, if any, of
    potentially dilutive common shares, such as stock options and
    warrants calculated using the treasury stock method. In periods
    with reported net operating losses, all stock options, unvested
    restricted stock and warrants are deemed anti-dilutive such that
    basic net loss per share and diluted net loss per share are
    equal.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;

    &lt;/tr&gt;

    &lt;b&gt;&lt;i&gt;Segment Information&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company currently operates in one business segment, which is
    the development and commercialization of Melphalan/HDS and
    CHEMOSAT. A single management team that reports to the CEO and
    President comprehensively manages the business. Accordingly, the
    Company does not have separately reportable segments.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 18px"&gt;
    &amp;#xA0;&lt;/p&gt;

    &lt;b&gt;&lt;i&gt;Foreign Currency and Currency Translation&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Transactions that are denominated in a foreign currency are
    remeasured into the functional currency at the current exchange
    rate on the date of the transaction. Any foreign
    currency-denominated monetary assets and liabilities are
    subsequently remeasured at current exchange rates, with gains or
    losses recognized as foreign exchange (losses)/gains in the
    statements of operations.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The assets and liabilities of the Company&amp;#x2019;s international
    subsidiaries are translated from their functional currencies into
    United States dollars at exchange rates prevailing at the balance
    sheet date. The majority of the foreign subsidiaries revenues and
    operating expenses are denominated in Euros. The reporting currency
    for the Company is the United States Dollar (&amp;#x201C;USD&amp;#x201D;).
    Average rates of exchange during the period are used to translate
    the statement of operations, while historical rates of exchange are
    used to translate any equity transactions.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Translation adjustments arising on consolidation due to differences
    between average rates and balance sheet rates, as well as
    unrealized foreign exchange gains or losses arising from
    translation of intercompany loans that are of a
    long-term-investment nature, are recorded in other comprehensive
    income.&lt;/p&gt;

    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In May 2014, the Financial Accounting Standards Board
    (&amp;#x201C;FASB&amp;#x201D;) issued Accounting Standards Update
    (&amp;#x201C;ASU&amp;#x201D;) &lt;font style="WHITE-SPACE: nowrap"&gt;2014-09,&lt;/font&gt; Revenue from Contracts with
    Customers, that updates the principles for recognizing revenue. The
    core principle of the guidance is that an entity should recognize
    revenue to depict the transfer of promised goods or services to
    customers in an amount that reflects the consideration to which the
    entity expects to be entitled in exchange for those goods or
    services. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2014-09&lt;/font&gt; also
    amends the required disclosures of the nature, amount, timing and
    uncertainty of revenue and cash flows arising from contracts with
    customers. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2014-09&lt;/font&gt; is
    effective for the Company beginning in its fiscal year 2018, and
    may be applied retrospectively to all prior periods presented or
    through a cumulative adjustment to the opening retained earnings
    balance in the year of adoption. The Company has adopted this
    guidance.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In June 2016, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-15,&lt;/font&gt; Statement of Cash Flows
    (Topic 230), which is intended to reduce diversity in practice in
    how certain transactions are classified in the statement of cash
    flows. The ASU is effective for public companies for fiscal years
    beginning after December&amp;#xA0;15, 2017, and interim periods within
    those fiscal years. Early adoption was permitted, including interim
    periods within those fiscal years provided that those electing
    early adoption must adopt all of the amendments in the same period.
    The guidance requires application using a retrospective transition
    method. The Company has adopted this guidance.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In October 2016, the FASB issues ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-16&lt;/font&gt; which simplifies the income
    tax consequences of intra-entity transfers other than inventory.
    Prior to ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-16,&lt;/font&gt; GAAL
    prohibited the recognition of current and deferred income taxes for
    intra-entity asset transfers until the asset has been sold to an
    outside party. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-16&lt;/font&gt;
    eliminates this prohibition for intra-entity transfers of assets
    other than inventory but retains the prohibition for intra-entity
    transfers of inventory. This standard is effective go r public
    entities for fiscal years beginning after December&amp;#xA0;15, 2017.
    The Company has adopted this guidance. The adoption did not have a
    material impact on the Company&amp;#x2019;s consolidated financial
    statements.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In November 2016, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-18,&lt;/font&gt; Statement of Cash Flows
    (Topic 230): Restricted Cash, which requires that the statement of
    cash flows explain the change during the period in the total of
    cash, cash equivalents, and amounts generally described as
    restricted cash or restricted cash equivalents. Entities are also
    required to reconcile such total to amounts on the balance sheet
    and disclose the nature of the restrictions. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-18&lt;/font&gt; is effective for fiscal years
    beginning after December&amp;#xA0;15, 2017 and interim periods within
    those fiscal years, and early adoption was permitted. The Company
    adopted this standard.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 18px"&gt;
    &amp;#xA0;&lt;/p&gt;

    &lt;b&gt;&lt;i&gt;SEC Disclosure Update and Simplification&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In August 2018, the SEC adopted the final rule under SEC Release
    &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;33-10532,&lt;/font&gt;
    Disclosure Update and Simplification, amending certain disclosure
    requirements that were redundant, duplicative, overlapping,
    outdated or superseded. In addition, the amendments expanded the
    disclosure requirements on the analysis of stockholders&amp;#x2019;
    equity for interim financial statements. Under the amendments, an
    analysis of changes in each caption of stockholders&amp;#x2019; equity
    presented in the balance sheet must be provided in a note or
    separate statement. The analysis should present a reconciliation of
    the beginning balance to the ending balance of each period for
    which a statement of comprehensive income is required to be filed.
    This final rule was effective on November&amp;#xA0;5, 2018. The
    adoption did not have a material impact on the Company&amp;#x2019;s
    consolidated financial statements.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
    &lt;b&gt;&lt;i&gt;Recent Accounting Standards to be Adopted&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In February 2016, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-02,&lt;/font&gt; Leases (Topic 842),
    superseding ASC Topic 840, Leases. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-02&lt;/font&gt; requires lessees to recognize
    a &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;right-of-use&lt;/font&gt;&lt;/font&gt; asset and a lease
    liability on their balance sheets for all the leases with terms
    greater than twelve months. Based on certain criteria, leases will
    be classified as either financing or operating, with classification
    affecting the pattern of expense recognition in the income
    statement. For leases with a term of twelve months or less, a
    lessee is permitted to make an accounting policy election by class
    of underlying asset not to recognize lease assets and lease
    liabilities. If a lessee makes this election, it should recognize
    lease expense for such leases generally on a straight-line basis
    over the lease term. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-02&lt;/font&gt; is effective for fiscal years
    beginning after December&amp;#xA0;15, 2018, and interim periods within
    those years, with early adoption permitted. In transition, lessees
    and lessors are required to recognize and measure leases at the
    beginning of the earliest period presented using a modified
    retrospective approach. In July 2018, the FASB issued ASU
    &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2018-11,&lt;/font&gt; Leases
    (Topic 842): Targeted Improvements that allows entities to apply
    the provisions of the new standard at the effective date (e.g.
    January&amp;#xA0;1, 2019), as opposed to the earliest period presented
    under the modified retrospective transition approach (January 1,
    2017) and recognize a cumulative-effect adjustment to the opening
    balance of retained earnings in the period of adoption. The
    modified retrospective approach includes a number of optional
    practical expedients primarily focused on leases that commenced
    before the effective date of Topic 842, including continuing to
    account for leases that commence before the effective date in
    accordance with previous guidance, unless the lease is modified.
    The Company is currently evaluating the effect the guidance will
    have on our audited consolidated financial statements.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In July 2017, the FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2017-11,&lt;/font&gt; Earnings Per Share (Topic
    260) Distinguishing Liabilities from Equity (Topic 480) Derivatives
    and Hedging (Topic 815). This guidance&amp;#xA0;was intended to reduce
    the complexity associated with the issuer&amp;#x2019;s accounting for
    certain financial instruments with characteristics of liabilities
    and equity. Specifically, the Board determined that a down round
    feature would no longer cause a freestanding equity-linked
    financial instrument (or an embedded conversion option) to be
    accounted for as a derivative liability at fair value with changes
    in fair value recognized in current earnings. In addition, the
    Board &lt;font style="WHITE-SPACE: nowrap"&gt;re-characterized&lt;/font&gt; the
    indefinite deferral of certain provisions of Topic 480 to a scope
    exception. The &lt;font style="WHITE-SPACE: nowrap"&gt;re-characterization&lt;/font&gt; has no accounting
    effect. ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2017-11&lt;/font&gt; is
    effective for public entities for fiscal years beginning after
    December&amp;#xA0;15, 2018. The Company intends to adopt this standard
    on January&amp;#xA0;1, 2019 and is evaluating the effects, if any, that
    the adoption of this guidance will have on the Company&amp;#x2019;s
    consolidated financial statements.&lt;/p&gt;

    The Company currently operates in one business segment, which is
    the development and commercialization of Melphalan/HDS and
    CHEMOSAT. A single management team that reports to the CEO and

    Company does not have separately reportable segments.&lt;/p&gt;

    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company accounts for its share-based compensation in accordance
    with the provisions of ASC 718, Stock-Based Compensation, which
    establishes accounting for equity instruments exchanged for
    employee services and ASC &lt;font style="WHITE-SPACE: nowrap"&gt;505-50,&lt;/font&gt; Equity-Based Payments to
    &lt;font style="WHITE-SPACE: nowrap"&gt;Non-Employees,&lt;/font&gt; which
    establishes accounting for equity-based payments to &lt;font style="WHITE-SPACE: nowrap"&gt;non-employees.&amp;#xA0;Under&lt;/font&gt; the
    provisions of ASC 718, share-based compensation is measured at the
    grant date, based upon the fair value of the award, and is
    recognized as an expense over the option holders&amp;#x2019; requisite
    service period (generally the vesting period of the equity grant).
    The Company is required to record compensation cost for all
    share-based payments granted to employees based upon the grant date
    fair value, estimated in accordance with the provisions of ASC 718.
    Under the provisions of ASC &lt;font style="WHITE-SPACE: nowrap"&gt;505-50,&lt;/font&gt; measurement of compensation
    cost related to common shares issued to &lt;font style="WHITE-SPACE: nowrap"&gt;non-employees&lt;/font&gt; for services is based on
    the value of the services provided or the fair value of the shares
    issued. The measurement of &lt;font style="WHITE-SPACE: nowrap"&gt;non-employee&lt;/font&gt; stock-based compensation
    is subject to periodic adjustment as the underlying equity
    instrument vests. The Company expenses its share-based compensation
    for share-based payments granted under the accelerated method,
    which treats each vesting tranche as if it were an individual
    grant.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company periodically grants stock options for a fixed number of
    shares of Common Stock to its employees, directors and &lt;font style="WHITE-SPACE: nowrap"&gt;non-employee&lt;/font&gt; contractors, with an
    exercise price greater than or equal to the fair market value of
    Delcath&amp;#x2019;s Common Stock at the date of the grant.&amp;#xA0;The
    Company estimates the fair value of stock options using an option
    pricing model.&amp;#xA0;Key inputs used to estimate the fair value of
    stock options include the exercise price of the award, the expected
    post-vesting option life, the expected volatility of
    Delcath&amp;#x2019;s stock over the option&amp;#x2019;s expected term, the
    risk-free interest rate over the option&amp;#x2019;s expected term, and
    Delcath&amp;#x2019;s expected annual dividend yield.&amp;#xA0;Estimates of
    fair value are not intended to predict actual future events or the
    value ultimately realized by persons who receive equity awards.&lt;/p&gt;

    Since January&amp;#xA0;1, 2019, the Company has issued 7.9&amp;#xA0;million
    shares pursuant to exercises of &lt;font style="WHITE-SPACE: nowrap"&gt;Pre-Funded&lt;/font&gt; Series D Warrants.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    As previously reported, in January&amp;#xA0;2019, the Company
    terminated Backstop Commitment Purchase Agreements with four
    institutional investors, by their mutual agreement. The Company and
    such institutional investors entered into Backstop Commitment
    Purchase Agreements in connection with a rights offering conducted
    by the Company that closed in September 2018 in which the Company
    proposed to raise up to $50&amp;#xA0;million by distributing, at no
    charge, to holders of its Common Stock &lt;font style="WHITE-SPACE: nowrap"&gt;non-transferable&lt;/font&gt; rights to subscribe
    for and purchase shares of the Company&amp;#x2019;s Common Stock at a
    price of $1.75 per share (the &amp;#x201C;Subscription Price&amp;#x201D;).
    Pursuant to the Backstop Commitment Purchase Agreements, such
    institutional investors agreed to purchase, at the Subscription
    Price, shares not issued in the rights offering following the
    expiration of the rights offering subscription period, subject to
    certain conditions, including the requirement that the closing
    price of a share of the Company&amp;#x2019;s Common Stock as reported by
    the OTCQB or higher market for each of the five business days
    immediately preceding a purchase exceeded the Subscription Price.
    The Backstop Commitment Purchase Agreements were terminated by
    mutual agreement of the parties thereto due to the fact that the
    closing price of the Company&amp;#x2019;s Common Stock had not exceeded
    the Subscription Price since October&amp;#xA0;1, 2018 and, thus, the
    institutional investors had no obligation to purchase shares.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On March&amp;#xA0;29, 2019, the Company exchanged all of its Series D
    Preferred Stock (with a stated value of $1,160,000) and received
    $400,000 in proceeds and issued a senior secured promissory note to
    an investor with a principal amount of $1,560,000. The note is due
    on April&amp;#xA0;1, 2020, bears interest at 8% per annum and is
    nonconvertible.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On April&amp;#xA0;19, 2019, April&amp;#xA0;26, 2019, May&amp;#xA0;9, 2019 and
    May&amp;#xA0;23, 2019, the Company borrowed an aggregate
    $3.3&amp;#xA0;million from two institutional investors and issued
    promissory notes to the investors. The promissory notes have an
    aggregate principal amount of $3.3&amp;#xA0;million, bear interest at
    the rate of 8% per annum and are due six months from the issuance
    of each note. The promissory notes are nonconvertible. The notes
    contain standard events of default and remedies therefor. The
    Company&amp;#x2019;s obligations under the promissory notes to the
    institutional investor are secured by a lien on the Company&amp;#x2019;s
    assets.&lt;/p&gt;

    On June&amp;#xA0;6, 2019, the Company entered into an agreement with
    two institutional investors, pursuant to which the investors agreed
    to transfer and surrender to the Company for cancellation of
    3.9&amp;#xA0;million Series D Warrants and 53.4&amp;#xA0;million
    &lt;font style="WHITE-SPACE: nowrap"&gt;Pre-Funded&lt;/font&gt; Series D
    Warrants. Under the terms of the Purchase Agreement, the investors
    agreed to defer the payment of the purchase price for the Series D
    Warrants and &lt;font style="WHITE-SPACE: nowrap"&gt;Pre-Funded&lt;/font&gt;
    Series D Warrants and, accordingly, the Company agreed to sell and
    issue to the investors 8% Senior Secured Promissory Notes in an
    aggregate principal amount of $2&amp;#xA0;million in full payment and
    satisfaction of the purchase price for the Series D Warrants and
    &lt;font style="WHITE-SPACE: nowrap"&gt;Pre-Funded&lt;/font&gt; Series D
    Warrants.&lt;/p&gt;

    On November&amp;#xA0;5, 2018, the Company&amp;#x2019;s Board authorized the
    establishment of a new series of preferred stock designated as
    Series D Preferred Stock, $0.01 par value, the terms of which are
    set forth in the certificate of designations for such series of
    Preferred Stock which was filed with the State of Delaware on
    November&amp;#xA0;5, 2018. On November&amp;#xA0;6, 2018 and
    November&amp;#xA0;30, 2018, the Company entered into a securities
    purchase agreements with an institutional investor which had
    purchased 101 shares of Series D Preferred Stock. At issuance, the
    Series D Preferred Stock would convert to 1,655,738 common
    shares.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On March&amp;#xA0;29, 2019, the Company exchanged all of its Series D
    Preferred Stock (with a stated value of $1,160,000) and received
    $400,000 in proceeds and issued a senior secured promissory note to
    an investor with a principal amount of $1,560,000. As a result, the
    Series D Preferred Stock is no longer outstanding.&lt;/p&gt;

    &lt;i&gt;February 2018 Financing&lt;/i&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In February 2018, the Company completed the sale of 424,000 shares
    of its Common Stock, 76,000 &lt;font style="WHITE-SPACE: nowrap"&gt;pre-funded&lt;/font&gt; warrants and the issuance
    of warrants to purchase 1.0&amp;#xA0;million common shares (the
    &amp;#x201C;February 2018 Warrants&amp;#x201D;) pursuant to a placement agent
    agreement, with net proceeds after expenses of $4.3&amp;#xA0;million.
    The February 2018 Warrants are exercisable one year after the
    anniversary date of their issuance. At December&amp;#xA0;31, 2018, the
    February 2018 Warrants were exercisable at $10.00 per share with
    0.2&amp;#xA0;million warrants outstanding. The Company allocated an
    estimated fair value of $18.3&amp;#xA0;million to the February 2018
    Warrants. The Company valued the February 2018 Warrants using the
    following inputs: exercise price of $10.00; contractual term of six
    years; volatility of 122.68% and risk-free rate of approximately
    one percent. Due to certain price protection features in the
    agreement, the February 2018 Warrants were accounted for as a
    derivative liability at issuance and will be subsequently marked to
    market through the statement of operations.&lt;/p&gt;

    In September 2018, the Company completed the sale of 4,667,811
    shares of its Common Stock, with net proceeds after expenses of
    approximately $7.0&amp;#xA0;million. The rights offering was made
    pursuant to a Registration Statement on Form &lt;font style="WHITE-SPACE: nowrap"&gt;S-1&lt;/font&gt; that was made effective on
    August&amp;#xA0;3, 2018.&lt;/p&gt;

    In December&amp;#xA0;2018, the Company entered into exchange agreements
    with several institutional investors with respect to their November
    2017 Warrants and February 2018 Warrants. The Company issued to the
    investors 0.8&amp;#xA0;million shares of Common Stock (the
    &amp;#x201C;Exchange Shares&amp;#x201D;) in exchange for the Existing
    Warrants (the &amp;#x201C;Exchange&amp;#x201D;). The Exchange was made in
    reliance upon the exemption from registration provided by
    Section&amp;#xA0;3(a)(9) of the Securities Act of 1933, as amended.&lt;/p&gt;

    3.7&amp;#xA0;million &lt;font style="WHITE-SPACE: nowrap"&gt;Pre-Funded&lt;/font&gt; Series D Warrants were

    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In October 2018, the Company filed a registration statement on Form
    &lt;font style="WHITE-SPACE: nowrap"&gt;S-3&lt;/font&gt; with the SEC, which
    was declared effective on December&amp;#xA0;21, 2018 and allows the
    Company to offer and sell, from time to time in one or more
    offerings, up to $100.0&amp;#xA0;million shares of Common Stock,
    preferred stock, warrants, debt securities and stock purchase
    contracts as it deems prudent or necessary to raise capital at a
    later date. The Company has lost its eligibility to use Form
    &lt;font style="WHITE-SPACE: nowrap"&gt;S-3&lt;/font&gt; due to the late filing
    of its Annual Report on Form &lt;font style="WHITE-SPACE: nowrap"&gt;10-K&lt;/font&gt; for the fiscal year ended
    December&amp;#xA0;31, 2018 and its late filing of its Quarterly Report

    As a result of the May&amp;#xA0;2, 2018 reverse stock split, the
    Company&amp;#x2019;s Stock Incentive Plan has no active grants and no
    further shares available to be granted.&lt;/p&gt;

    As previously reported, on February&amp;#xA0;1, 2019 the Board of
    Directors of the Company adopted the Company&amp;#x2019;s 2019 Equity
    Incentive Plan (the &amp;#x201C;2019 Plan&amp;#x201D;), pursuant to which
    1,500,000 shares of Common Stock of the Company are available for
    grants through February&amp;#xA0;1, 2029 to the Company&amp;#x2019;s
    employees, directors and consultants. On February&amp;#xA0;1, 2019,
    options to purchase 1,250,000 shares of Common Stock, at an
    exercise price of $0.281 per share, were granted under the 2019
    Plan to certain executive officers and employees of the Company.
    The stock options are vesting over a period of one year commencing
    from the date of grant in twelve equal monthly increments
    commencing on the one month anniversary of the grant date. The
    stock options carry a ten year term and expire on February&amp;#xA0;1,
    2029.&lt;/p&gt;

    The Company bases its estimates and judgments on historical
    experience and on various other assumptions that it believes are
    reasonable under the circumstances. The amounts of assets and
    liabilities reported in the Company&amp;#x2019;s consolidated balance
    sheets and the amount of revenues and expenses reported for each of
    the periods presented are affected by estimates and assumptions,
    which are used for, but not limited to, the accounting for
    derivative instrument liabilities, stock-based compensation,
    valuation of inventory, impairment of long-lived assets, income
    taxes and operating expense accruals. Such assumptions and
    estimates are subject to change in the future as additional
    information becomes available or as circumstances are modified.
    Actual results could differ from these estimates.&lt;/p&gt;

    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On June&amp;#xA0;4, 2018, July&amp;#xA0;21, 2018, August&amp;#xA0;29, 2018, and
    September&amp;#xA0;21, 2018, the Company issued 8% senior secured
    convertible notes (collectively, &amp;#x201C;the Notes&amp;#x201D;) to
    investors with aggregate principal of $9.4&amp;#xA0;million and
    maturity dates between December 2018 and March 2021. The Notes are
    secured pursuant to a Security Agreement which creates a first
    priority security interest in all of the personal property (other
    than Excluded Collateral (as defined in the Security Agreement) of
    the Company of every kind and description, tangible or intangible,
    whether currently owned and existing or created or acquired in the
    future. At December&amp;#xA0;31, 2018, the Notes were convertible at
    $1.75 per share subject to customary terms.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In April 2019, the Company received notices of default from the

    In connection with the issuance of the Notes, the Company also
    issued 4.2&amp;#xA0;million Series D Warrants with exercise prices
    ranging from $1.75&amp;#x2014;$4.00 and 65.0&amp;#xA0;million &lt;font style="WHITE-SPACE: nowrap"&gt;Pre-Funded&lt;/font&gt; Series D Warrants with a
    purchase price of $0.01. The warrants expire 5 years from the date
    they could first be exercised. The provisions in the Series D
    Warrants and &lt;font style="WHITE-SPACE: nowrap"&gt;Pre-Funded&lt;/font&gt;
    Series D Warrants issued in June 2018 required the Company to
    initially account for the warrants as derivative liabilities. The
    warrants were valued at $5.1&amp;#xA0;million. As a result, the Company
    recognized a discount to debt of $2.3&amp;#xA0;million and a loss on
    issuance of a financial instrument of $2.8&amp;#xA0;million.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;

    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In July 2018, the Company and the investor from the June&amp;#xA0;2018
    transaction amended the June 2018 &lt;font style="WHITE-SPACE: nowrap"&gt;Pre-Funded&lt;/font&gt; Series D Warrants so that
    they are exercisable as of July&amp;#xA0;20, 2018 and the Company may
    redeem them at any time the Notes are no longer outstanding and the
    Company is not in default. The Company and the investor from the
    June 2018 transaction also amended the definition of a Fundamental
    Transaction in the June 2018 Warrants. This amendment resulted in
    $4.2&amp;#xA0;million related to the fair value of the June 2018
    Warrants being reclassified from a liability to equity.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
    &lt;i&gt;Amendment to June 2018 and July 2018 Notes and &lt;font style="WHITE-SPACE: nowrap"&gt;Pre-Funded&lt;/font&gt; Warrants&lt;/i&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In August 2018, the Company amended its June 2018 Notes and July
    2018 Notes such that the conversion price was reduced to $1.75,
    interest shall accrue until maturity, and the first
    $2.5&amp;#xA0;million and 50% of any subsequent financings shall be
    used to satisfy the Company&amp;#x2019;s obligations under the Notes.
    Effective the same date, the Company also amended its &lt;font style="WHITE-SPACE: nowrap"&gt;Pre-Funded&lt;/font&gt; Warrants such that the
    total number of June&amp;#xA0;2018 &lt;font style="WHITE-SPACE: nowrap"&gt;Pre-Funded&lt;/font&gt; Warrants was increased from
    13.0&amp;#xA0;million to 22.2&amp;#xA0;million and the total number of July
    2018 &lt;font style="WHITE-SPACE: nowrap"&gt;Pre-Funded&lt;/font&gt; Warrants
    was increased from 9.2&amp;#xA0;million to 15.8&amp;#xA0;million. This
    amendment was accounted for as an extinguishment of debt as the
    change in cash flows exceeded 10%. The original June 2018 and July
    2018 notes were written off and the amended June 2018 and July 2018
    Notes were recorded at fair value as of the date of this amendment.
    The Company recorded $1.1&amp;#xA0;million loss on debt extinguishment
    related to this amendment.&lt;/p&gt;

    The accompanying financial statements have been prepared on a going
    concern basis, which contemplates the realization of assets and the
    satisfaction of liabilities in the normal course of business. As
    shown in the accompanying financial statements during the year
    ended December&amp;#xA0;31, 2018, the Company incurred net losses of
    $19.2&amp;#xA0;million and used $14.7&amp;#xA0;million of cash for its
    operating activities. These factors among others raise substantial
    doubt about the Company&amp;#x2019;s ability to continue as a going
    concern for a reasonable period of time.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company&amp;#x2019;s existence is dependent upon management&amp;#x2019;s
    ability to obtain additional funding sources or to enter into
    strategic alliances. Adequate additional financing may not be
    available to us on acceptable terms, or at all. If the Company is
    unable to raise additional capital and/or enter into strategic
    alliances when needed or on attractive terms, it would be forced to
    delay, reduce or eliminate our research and development programs or
    any commercialization efforts. There can be no assurance that the
    Company&amp;#x2019;s efforts will result in the resolution of the
    Company&amp;#x2019;s liquidity needs. If Delcath is not able to continue
    as a going concern, it is likely that holders of its Common Stock
    will lose all of their investment. The accompanying consolidated
    financial statements do not include any adjustments that might
    result should the Company be unable to continue as a going
    concern.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company anticipates incurring additional losses until such
    time, if ever, that it can generate significant sales. At
    December&amp;#xA0;31, 2018, management believed that its capital
    resources were adequate to fund operations through March 2019.
    Additional working capital will be required to continue operations.
    Operations of the Company are subject to certain risks and
    uncertainties, including, among others, uncertainty of product
    development and clinical trial results; uncertainty regarding
    regulatory approval; technological uncertainty; uncertainty
    regarding patents and proprietary rights; comprehensive government
    regulations; limited commercial manufacturing, marketing or sales
    experience; and dependence on key personnel. See Note 15 of these
    notes to the Company&amp;#x2019;s audited consolidated financial
    statements relating to subsequent events.&lt;/p&gt;

    License fees and milestones received in exchange for the grant of a
    license for the commercialization of CHEMOSAT are generally
    recognized over the development period, as the license is
    considered distinct from the delivery of product. Milestone
    payments that are contingent upon the occurrence of future events,
    are evaluated and recorded at the most likely amount, and to the
    extent that it is probable that a significant reversal will not
    occur when the associated uncertainty is resolved.&lt;/p&gt;
    &lt;/div&gt;

    On April&#xA0;19, 2019, April&#xA0;26, 2019, May&#xA0;9, 2019 and
    May&#xA0;23, 2019, the Company issued 8% senior secured notes
    (collectively, the &#x201C;2019 Notes&#x201D;) in the aggregate
    principal amount of $3.3&#xA0;million, to two institutional
    investors. The 2019 Notes bore interest at the rate of 8% per annum
    and were to mature on the six month anniversary of issuance in each
    case. The 2019 Notes were not convertible. The 2019 Notes contained
    standard events of default and remedies and are secured by a lien
    on the Company&#x2019;s assets. The 2019 Notes were exchanged as
    part of the recent equity financing discussed further in Note 14
    and are no longer outstanding.</p>

    In March 2019, the Company exchanged all issued and outstanding
    shares of its Series D Preferred Stock (having an aggregate stated
    value of $1,160,000) and received $400,000 in cash proceeds in
    exchange for a senior secured promissory note (the &#x201C;March
    2019 Note&#x201D;) in the principal amount of $1,560,000. The March
    2019 Note bore interest at the rate of 8% per annum, and were to
    mature on April&#xA0;1, 2020, and was not convertible. The
    principal is recognized in notes payable on the Condensed
    Consolidated Balance Sheet. The March 2019 Note was exchanged as
    part of the recent equity financing discussed further in Note 14

    convertible notes (collectively, &#x201C;the 2018 Notes&#x201D;) in
    the aggregate principal amount of $9.4&#xA0;million to several
    institutional investors. The 2018 Notes bore interest at the rate
    of 8% per annum and had maturity dates between December 2018 and
    March 2021. The 2018 Notes were initially convertible and secured
    pursuant to a Security Agreement which created a first priority
    security interest in all of the personal property (other than
    Excluded Collateral as defined in the Security Agreement) of the
    Company of every kind and description, tangible or intangible,
    whether currently owned and existing or created or acquired in the
    future. In March 2019, the Company amended the June 2018, July 2018
    and August 2018 Notes to make them <font style="WHITE-SPACE: nowrap">non-convertible.</font> There was no impact
    to the financial statements. In April 2019, the Company received
    notices of default from the investors in the 2018 Notes which
    resulted in a 25%, or $1.1&#xA0;million, increase in principal and
    an increase in the interest rates from 8% to 18%. The 2018 Notes
    were exchanged as part of the recent equity financing discussed
    further in Note 14 and are no longer outstanding.</p>

    As discussed in Note 14 <i>Income Taxes</i> to the Consolidated
    Financial Statements included in the Company&#x2019;s Annual Report
    filed for the fiscal year ended December&#xA0;31, 2018, the Company
    has a valuation allowance against the full amount of its net
    deferred tax assets. The Company currently provides a valuation
    allowance against deferred tax assets when it is more likely than
    not that some portion or all of its deferred tax assets will not be
    realized. The Company has not recognized any unrecognized tax
    benefits in its balance sheet.</p>

    The Company is subject to income tax in the U.S., as well as
    various state and international jurisdictions. The federal and
    state tax authorities can generally reduce a net operating loss
    (but not create taxable income) for a period outside the statute of
    limitations in order to determine the correct amount of net
    operating loss which may be allowed as a deduction against income
    for a period within the statute of limitations. Additional
    information regarding the statutes of limitations can be found in
    Note 14 <i>Income Taxes</i> to the Consolidated Financial
    Statements included in the Company&#x2019;s Annual Report filed for
    the fiscal year ended December&#xA0;31, 2018.</p>

    As of December&#xA0;31, 2018 and 2017 the Company had net operating
    loss carryforwards for U.S. federal income tax purposes of
    approximately $230.0&#xA0;million and $211.3&#xA0;million
    respectively. A significant portion of the federal amount is
    subject to an annual limitation as low as $27,500 as a result of
    changes in the Company&#x2019;s ownership in May 2003, November
    2016, and multiple dates throughout 2017 and 2018, as defined by
    Federal Internal Revenue Code Section&#xA0;382 and the related
    income tax regulations. As a result of the limitations caused by
    the May 2003, November 2016 and multiple 2017 and 2018 ownership
    changes, approximately $208.1&#xA0;million of the total net
    operating loss carryforwards is expected to expire unutilized and
    will be unavailable to offset future federal taxable income.
    Approximately $21.9&#xA0;million of net operating loss
    carryforwards remains available to offset future federal taxable
    income, of which $1.7&#xA0;million will expire between 2019 and
    2037 and $20.2&#xA0;million will have an unlimited carryforward
    period as a result of the Tax Cuts and Jobs Act.</p>

    In addition, the Company&#x2019;s state net operating losses are
    also subject to annual limitations that generally follow the
    federal Section&#xA0;382 provisions (with the exception of
    Connecticut), adjusted for each state&#x2019;s respective income
    apportionment percentages. As of December&#xA0;31, 2018 and 2017,
    the Company had net operating loss carryforwards for state and city
    income tax purposes between approximately $27.3&#xA0;million and
    $167.3&#xA0;million and between approximately $27.3&#xA0;million
    and $150.3&#xA0;million, respectively, which expire through 2038.
    As a result of the 382 limitations, approximately
    $157.2&#xA0;million and $141.5 million of New York State and New
    York City net operating losses are expected to expire unutilized
    and will be unavailable to offset future taxable income.
    Approximately $10.1&#xA0;million and $10.1&#xA0;million of net
    operating loss carryforwards, respectively, will be available to
    offset future state and city taxable income. As of
    December&#xA0;31, 2018 and 2017 the Company had a net operating
    loss carryforward for foreign income tax purposes of
    $25.2&#xA0;million and $25.0&#xA0;million, respectively, which have
    indefinite carryforward periods. As of December&#xA0;31, 2018 and
    2017, the Company had federal research and development tax credit
    carryforwards of approximately $5.0&#xA0;million and
    $4.3&#xA0;million respectively, which expire through 2038. As a
    result of the section 382 limitations, all but $0.2&#xA0;million of
    the tax credit carryforwards is expected to expire unutilized.</p>

    Management has established a 100% valuation allowance against the
    deferred tax assets as management does not believe it is more
    likely than not that these assets will be realized. The
    Company&#x2019;s valuation allowance decreased by approximately
    $5.4&#xA0;million and decreased by $1.1&#xA0;million in 2018 and
    2017, respectively. The change in valuation allowance is as

    On December&#xA0;22, 2017, the United States enacted the Tax Cuts
    and Jobs Act (the &#x201C;Act&#x201D;). The Act, which is also
    commonly referred to as &#x201C;U.S. tax reform&#x201D;,
    significantly changes U.S. corporate income tax laws by, among
    other provisions, reducing the maximum U.S. corporate income tax
    rate from 35% to 21% starting in 2018. During the year ended
    December&#xA0;31, 2017, the Company reduced deferred tax assets by
    a provisional amount of $143,500, offset by a corresponding
    reduction to its valuation allowance, as a result of the
    <font style="WHITE-SPACE: nowrap">re-measurement</font> of deferred
    tax assets and liabilities from its 34% effective rate under
    existing law to the new lower statutory rate of 21%. The Company
    finalized its accounting of the effects of tax reform in 2018,
    which resulted in insignificant adjustments.</p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    The Act also requires a mandatory <font style="WHITE-SPACE: nowrap">one-time</font> inclusion of the deferred
    foreign income of controlled foreign corporations. The <font style="WHITE-SPACE: nowrap">one-time</font> transition tax is based on
    Delcath&#x2019;s total post-1986 earnings and profits (E&amp;P) for
    which the Company has previously deferred from U.S. income taxes.
    During the year ended December&#xA0;31, 2017, the Company&#x2019;s
    reasonable estimate resulted in no provisional amount for the
    <font style="WHITE-SPACE: nowrap">one-time</font> transition tax
    liability, as the Company&#x2019;s international subsidiaries are
    expected to have a cumulative deficit in E&amp;P. As the
    Company&#x2019;s international subsidiaries have a cumulative
    deficit in earnings and profits, the Company did not anticipate
    being affected by the mandatory inclusion provisions of the Act.
    The Company finalized its calculation of the total post-1986
    foreign E&amp;P (including deficits) for these foreign subsidiaries
    during 2018 and was not impacted by the mandatory inclusion
    provisions of the Act.</p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    On December, 22, 2017, Staff Accounting Bulletin 118 was issued due
    to the complexities involved in accounting for the recently enacted
    Act. SAB 118 requires the Company to include in its financial
    statements a reasonable estimate of the impact of the Act on
    earnings to the extent such estimate has been determined.
    Accordingly, the U.S. provision for income tax for
    December&#xA0;31, 2017 was based on the reasonable estimate
    guidance provided by SAB 118. The Company finalized the impact from
    the Act and recorded insignificant adjustments.</p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    The Company complies with the provisions of ASC <font style="WHITE-SPACE: nowrap">740-10,</font> Income Taxes, in accounting
    for its uncertain tax positions. ASC <font style="WHITE-SPACE: nowrap">740-10</font> addresses the determination of
    whether tax benefits claimed or expected to be claimed on a tax
    return should be recorded in the financial statements. Under ASC
    <font style="WHITE-SPACE: nowrap">740-10,</font> the Company may
    recognize the tax benefit from an uncertain tax position only if it
    is more likely than not that the tax position will be sustained on
    examination by the taxing authorities, based on the technical
    merits of the position. The Company has determined that the Company
    has no significant uncertain tax positions requiring recognition
    under ASC <font style="WHITE-SPACE: nowrap">740-10</font> and
    therefore has not included a tabular rollforward of unrecognized
    tax benefits. As there are no uncertain tax positions recognized,
    interest and penalties have not been accrued.</p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    The Company is subject to income tax in the U.S., as well as
    various state and international jurisdictions. The Company has not
    been audited by any state tax authorities in connection with income
    taxes. The Company has not been audited by international tax
    authorities or any states in connection with income taxes. The
    Company&#x2019;s New York State tax returns have been subject to
    annual desk reviews which have resulted in insignificant
    adjustments to the related franchise tax liabilities and credits.
    The Company is no longer subject to federal and state examination
    for tax years ending prior to December&#xA0;31, 2015; tax years
    ending December&#xA0;31, 2015 through December&#xA0;31, 2018 remain
    open to examination. The Republic of Ireland is the Company&#x2019;s
    only significant foreign jurisdiction. The Company is no longer
    subject to Ireland tax examination for tax years ending prior to
    December&#xA0;31, 2014 (as Ireland has not initiated an audit of
    2013 as of December&#xA0;31, 2018); tax years ending
    December&#xA0;31, 2014 through December&#xA0;31, 2018 remain open
    to examination. However, the Company&#x2019;s tax years
    December&#xA0;31, 1998 through December&#xA0;31, 2018 generally
    remain open to adjustment for all federal, state and foreign tax
    matters until its net operating loss and tax credit carryforwards
    are utilized or expire prior to utilization, and the applicable
    statutes of limitation have expired in the utilization year. The
    federal and state tax authorities can generally reduce a net
    operating loss (but not create taxable income) for a period outside
    the statute of limitations in order to determine the correct amount
    of net operating loss which may be allowed as a deduction against
    income for a period within the statute of limitations.</p>

    Basic net loss per share is determined by dividing net loss by the
    weighted average shares of common stock outstanding during the
    period, without consideration of potentially dilutive securities
    except for those shares that are issuable for little or no cash
    consideration. Diluted net loss per share is determined by dividing
    net loss by diluted weighted average shares outstanding. Diluted
    weighted average shares reflects the dilutive effect, if any, of
    potentially dilutive common shares, such as stock options and
    warrants calculated using the treasury stock method. In periods
    with reported net operating losses, all common stock options and
    warrants are generally deemed anti-dilutive such that basic net
    loss per share and diluted net loss per share are equal. However,
    in certain periods in which the exercise price of the warrants was
    less than the last reported sales price of Delcath&#x2019;s common
    stock on the final trading day of the period and there is a gain
    recorded pursuant to the change in fair value of the warrant
    derivative liability, the impact of gains related to the
    <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">mark-to-market</font></font> adjustment of
    the warrants outstanding at the end of the period is reversed and
    the treasury stock method is used to determine diluted earnings per
    share.</p>

    As previously reported, on March&#xA0;26, 2019, the Company
    commenced an action (the &#x201C;Action&#x201D;) in the Commercial
    Division of the Supreme Court for the State of New York, County of
    New York, captioned <u>Delcath Systems, Inc., v. Iroquois Capital
    Investment Group LLC, Iroquois Master Fund Ltd., L1 Capital Global
    Opportunities Master Fund and First Fire Global</u>
    <u>Opportunities Fund LLC</u> (Index No.&#xA0;651749/2019). The
    Action sought expedited equitable relief in the form of reformation
    and a declaratory judgement to remedy a scrivener&#x2019;s error
    made in connection with the Series D Warrants issued in the
    Company&#x2019;s February 2018 public offering such that those
    warrants did not contain a price and quantity ratchet upon a sale
    of Company securities at a price lower than the offering price in

    Fund, settled with the Company by exchanging its Series D Warrants
    for the Company&#x2019;s common stock on a <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">one-for-one</font></font> basis, which is the
    same ratio for which other investors in the February 2018 round
    exchanged their Series D Warrants in December 2018. The Company and
    the remaining defendants in the Action, Iroquois Capital Investment
    Group LLC, Iroquois Master Fund Ltd. and First Fire Global
    Opportunities Fund LLC, entered into a settlement agreement on
    April&#xA0;18, 2019 pursuant to which such defendants surrendered
    their Series D Warrants and waived all rights granted to them by or
    in connection with the Series D Warrants and all rights afforded to
    them to participate in the Company&#x2019;s future common stock
    offerings. In consideration therefor, pursuant to the settlement
    agreement, (i)&#xA0;the Company paid <font style="WHITE-SPACE: nowrap">one-fifth</font> of the reasonable fees and
    expenses of defendants&#x2019; counsel incurred in connection with
    the Action and negotiation of the settlement agreement, the total
    of which shall not exceed $50,000 (the &#x201C;Settlement
    Fees&#x201D;) and (ii)&#xA0;subject to the Company securing and
    closing certain contemplated financing, the Company agreed to pay
    to the defendants $400,000 and the remaining Settlement Fees. On
    July&#xA0;17, 2019, the Company paid the amount of $440,000 to the
    defendants pursuant to the settlement agreement from the net
    proceeds received by the Company in the closing of a private
    placement transaction discussed in Note 14 below. No amounts remain
    payable under the settlement and the Action is now fully
    settled.</p>

    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    The Company bases its estimates and judgments on historical
    experience and on various other assumptions that it believes are
    reasonable under the circumstances. The amounts of assets and
    liabilities reported in the Company&#x2019;s consolidated balance
    sheets and the amount of revenues and expenses reported for each of
    the periods presented are affected by estimates and assumptions,
    which are used for, but not limited to, the accounting for
    derivative instrument liabilities, stock-based compensation,
    valuation of inventory, impairment of long-lived assets, income
    taxes and operating expense accruals. Such assumptions and
    estimates are subject to change in the future as additional
    information becomes available or as circumstances are modified.
    Actual results could differ from these estimates.</p>

    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    The Company considers investments with original maturities of three
    months or less at date of acquisition to be cash equivalents. The
    Company has deposits that exceed amounts insured by the Federal
    Deposit Insurance Corporation (&#x201C;FDIC&#x201D;), however, the
    Company does not consider this a significant concentration of
    credit risk based on the strength of the financial institution.</p>

    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    Accounts receivable, principally trade, are generally due within 30
    days and are stated at amounts due from customers. Collections and
    payments from customers are monitored and a provision for estimated
    credit losses may be created based upon historical experience and
    specific customer collection issues that may be identified.</p>

    Inventories are valued at the lower of cost or market value using
    the <font style="WHITE-SPACE: nowrap">first-in,</font> <font style="WHITE-SPACE: nowrap">first-out</font> method.&#xA0;The reported
    net value of inventory includes finished saleable products,
    <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">work-in-process,</font></font> and raw
    materials that will be sold or used in future periods.&#xA0;The

    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    Property, plant and equipment are recorded at cost, less
    accumulated depreciation. The Company provides for depreciation on
    a straight line basis over the estimated useful lives of the assets
    which range from three to seven years. Leasehold improvements will
    be amortized over the shorter of the lease term or the estimated
    useful life of the related assets when they are placed into
    service. The Company evaluates property, plant and equipment for
    impairment periodically to determine if changes in circumstances or
    the occurrence of events suggest the carrying value of the asset or
    asset group may not be recoverable. Maintenance and repairs are
    charged to operations as incurred. Expenditures which substantially
    increase the useful lives of the related assets are
    capitalized.</p>

    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    The Company accounts for derivative instruments in accordance with
    Accounting Standards Codification (&#x201C;ASC&#x201D;) 815,
    Derivatives and Hedging, which establishes accounting and reporting
    standards for derivative instruments and hedging activities,
    including certain derivative instruments embedded in other
    financial instruments or contracts and requires recognition of all
    derivatives on the balance sheet at fair value, regardless of the
    hedging relationship designation. Accounting for changes in the
    fair value of the derivative instruments depends on whether the
    derivatives qualify as hedge relationships and the types of
    relationships designated are based on the exposures hedged. At
    December&#xA0;31, 2018 and 2017, the Company did not have any
    derivative instruments that were designated as hedges.</p>

    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    The Company adheres to ASC 820, Fair Value Measurement, which
    defines fair value, establishes a framework for measuring fair
    value, and expands disclosures about fair value measurements. ASC
    820 applies to reported balances that are required or permitted to
    be measured at fair value under existing accounting pronouncements;
    accordingly, the standard does not require any new fair value
    measurements of reported balances.</p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    ASC 820 emphasizes that fair value is a market-based measurement,
    not an entity-specific measurement.&#xA0;Therefore, a fair value
    measurement should be determined based on the assumptions that
    market participants would use in pricing the asset or
    liability.&#xA0;As a basis for considering market participant
    assumptions in fair value measurements, ASC 820 establishes a fair
    value hierarchy that distinguishes between market participant
    assumptions based on market data obtained from sources independent
    of the reporting entity (observable inputs that are classified
    within Levels 1 and 2 of the hierarchy) and the reporting
    entity&#x2019;s own assumptions about market participant assumptions
    (unobservable inputs classified within Level&#xA0;3 of the
    hierarchy).</p>

    In instances where the determination of the fair value measurement
    is based on inputs from different levels of the fair value
    hierarchy, the level in the fair value hierarchy within which the

    input that is significant to the fair value measurement in its
    entirety. The Company&#x2019;s assessment of the significance of a
    particular input to the fair value measurement in its entirety
    requires judgment and considers factors specific to the asset or

    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    Revenue is generated from proprietary and partnered product sales
    and license and royalty arrangements. Revenue is recognized when or
    as we transfer control of the promised goods or services to our
    customers in an amount that reflects the consideration to which we
    expect to be entitled to in exchange for those goods or services.
    When obligations or contingencies remain after the products are
    shipped, such as training and certifying the treatment centers,
    revenue is deferred until the obligations or contingencies are
    satisfied.</p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    We may enter into contracts with partners that contain multiple
    elements such as licensing, development, manufacturing and
    commercialization components. These arrangements are often complex
    and we may receive various types of consideration over the life of
    the arrangement, including: <font style="WHITE-SPACE: nowrap">up-front</font> fees, reimbursements for
    research and development services, milestone payments, payments on
    product shipments, margin sharing arrangements, license fees and
    royalties.</p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    Our results of operations for reporting periods beginning on or
    after January&#xA0;1, 2018 are presented under ASC 606, Revenue
    from Contracts with Customers, while prior period amounts, as
    reported, are not adjusted. The effects of the adoption of the new
    standard in 2018 were not material to our consolidated financial
    statements. In assessing our revenue arrangements in accordance
    with ASC 606, Revenue from Contracts with Customers, we must
    identify the contract, determine the transaction price including an
    estimation of any variable consideration we expect to receive in
    connection with the contract, identify the promises of goods or
    services to the customer and each distinct performance obligation,
    allocate the transaction price to each of the performance
    obligations, and recognize revenue when or as the performance
    obligations are satisfied. Each of these steps in the revenue
    recognition process requires management to make judgements and/or
    estimates. The most significant judgements and estimates involve
    the determination of variable consideration to be included in the
    transaction price. Variable consideration is recognized at an
    amount we believe is not subject to significant reversal and is
    adjusted at each reporting period if the most likely amount of
    expected consideration changes or becomes fixed. We believe this
    provides a reasonable basis for recognizing revenue, however,
    actual results could differ from estimates and significant changes
    in estimates could impact our results of operations in future
    periods.</p>

    The Company is required to record compensation cost for all
    share-based payments granted to employees based upon the grant date
    fair value, estimated in accordance with the provisions of ASC 718.
    Under the provisions of ASC <font style="WHITE-SPACE: nowrap">505-50,</font> measurement of compensation
    cost related to common shares issued to <font style="WHITE-SPACE: nowrap">non-employees</font> for services is based on

    The Company periodically grants stock options for a fixed number of
    shares of Common Stock to its employees, directors and <font style="WHITE-SPACE: nowrap">non-employee</font> contractors, with an
    exercise price greater than or equal to the fair market value of
    Delcath&#x2019;s Common Stock at the date of the grant.&#xA0;The
    Company estimates the fair value of stock options using an option
    pricing model.&#xA0;Key inputs used to estimate the fair value of
    stock options include the exercise price of the award, the expected
    post-vesting option life, the expected volatility of
    Delcath&#x2019;s stock over the option&#x2019;s expected term, the
    risk-free interest rate over the option&#x2019;s expected term, and
    Delcath&#x2019;s expected annual dividend yield.&#xA0;Estimates of
    fair value are not intended to predict actual future events or the
    value ultimately realized by persons who receive equity awards.</p>

    <b><i>Income Taxes</i></b></p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    The Company accounts for income taxes following the asset and
    liability method in accordance with the ASC 740, Income Taxes.
    Under such method, deferred tax assets and liabilities are
    recognized for the future tax consequences attributable to
    differences between the consolidated financial statement carrying
    amounts of existing assets and liabilities and their respective tax
    bases. The Company applies the accounting guidance issued to
    address the accounting for uncertain tax positions. This guidance
    clarifies the accounting for income taxes, by prescribing a minimum
    recognition threshold a tax position is required to meet before
    being recognized in the financial statements as well as provides
    guidance on derecognition, measurement, classification, interest
    and penalties, accounting in interim periods, disclosure and
    transition. The Company classifies interest and penalty expense
    related to uncertain tax positions as a component of income tax
    expense. Deferred tax assets and liabilities are measured using
    enacted tax rates expected to apply to taxable income in the years
    that the asset is expected to be recovered or the liability
    settled. A valuation allowance is provided when it is more likely
    than not that some portion or all of a deferred tax asset will not
    be realized. The ultimate realization of deferred tax assets
    depends on the generation of future taxable income during the
    period in which related temporary differences become deductible.
    The Company considers the scheduled reversal of deferred tax
    liabilities, projected future taxable income and tax planning
    strategies in its assessment of a valuation allowance. See Note 14
    for additional information.</p>

    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    Basic net loss per share is determined by dividing net loss by the
    weighted average shares of Common Stock outstanding during the
    period. Diluted net loss per share is determined by dividing net
    loss by diluted weighted average shares outstanding. Diluted
    weighted average shares reflects the dilutive effect, if any, of
    potentially dilutive common shares, such as stock options and
    warrants calculated using the treasury stock method. In periods
    with reported net operating losses, all stock options, unvested
    restricted stock and warrants are deemed anti-dilutive such that
    basic net loss per share and diluted net loss per share are

    In May 2014, the Financial Accounting Standards Board
    (&#x201C;FASB&#x201D;) issued Accounting Standards Update
    (&#x201C;ASU&#x201D;) <font style="WHITE-SPACE: nowrap">2014-09,</font> Revenue from Contracts with
    Customers, that updates the principles for recognizing revenue. The
    core principle of the guidance is that an entity should recognize
    revenue to depict the transfer of promised goods or services to
    customers in an amount that reflects the consideration to which the
    entity expects to be entitled in exchange for those goods or
    services. ASU <font style="WHITE-SPACE: nowrap">2014-09</font> also
    amends the required disclosures of the nature, amount, timing and
    uncertainty of revenue and cash flows arising from contracts with
    customers. ASU <font style="WHITE-SPACE: nowrap">2014-09</font> is
    effective for the Company beginning in its fiscal year 2018, and
    may be applied retrospectively to all prior periods presented or
    through a cumulative adjustment to the opening retained earnings
    balance in the year of adoption. The Company has adopted this
    guidance.</p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    In June 2016, the FASB issued ASU <font style="WHITE-SPACE: nowrap">2016-15,</font> Statement of Cash Flows
    (Topic 230), which is intended to reduce diversity in practice in
    how certain transactions are classified in the statement of cash
    flows. The ASU is effective for public companies for fiscal years
    beginning after December&#xA0;15, 2017, and interim periods within
    those fiscal years. Early adoption was permitted, including interim
    periods within those fiscal years provided that those electing
    early adoption must adopt all of the amendments in the same period.
    The guidance requires application using a retrospective transition
    method. The Company has adopted this guidance.</p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    In October 2016, the FASB issues ASU <font style="WHITE-SPACE: nowrap">2016-16</font> which simplifies the income
    tax consequences of intra-entity transfers other than inventory.
    Prior to ASU <font style="WHITE-SPACE: nowrap">2016-16,</font> GAAL
    prohibited the recognition of current and deferred income taxes for
    intra-entity asset transfers until the asset has been sold to an
    outside party. ASU <font style="WHITE-SPACE: nowrap">2016-16</font>
    eliminates this prohibition for intra-entity transfers of assets
    other than inventory but retains the prohibition for intra-entity
    transfers of inventory. This standard is effective go r public
    entities for fiscal years beginning after December&#xA0;15, 2017.
    The Company has adopted this guidance. The adoption did not have a

    In November 2016, the FASB issued ASU <font style="WHITE-SPACE: nowrap">2016-18,</font> Statement of Cash Flows

    cash flows explain the change during the period in the total of

    greater than twelve months. Based on certain criteria, leases will
    be classified as either financing or operating, with classification
    affecting the pattern of expense recognition in the income
    statement. For leases with a term of twelve months or less, a
    lessee is permitted to make an accounting policy election by class
    of underlying asset not to recognize lease assets and lease
    liabilities. If a lessee makes this election, it should recognize
    lease expense for such leases generally on a straight-line basis
    over the lease term. ASU <font style="WHITE-SPACE: nowrap">2016-02</font> is effective for fiscal years
    beginning after December&#xA0;15, 2018, and interim periods within

    and lessors are required to recognize and measure leases at the
    beginning of the earliest period presented using a modified
    retrospective approach. In July 2018, the FASB issued ASU
    <font style="WHITE-SPACE: nowrap">No.&#xA0;2018-11,</font> Leases

    under the modified retrospective transition approach (January 1,
    2017) and recognize a cumulative-effect adjustment to the opening
    balance of retained earnings in the period of adoption. The
    modified retrospective approach includes a number of optional
    practical expedients primarily focused on leases that commenced
    before the effective date of Topic 842, including continuing to
    account for leases that commence before the effective date in
    accordance with previous guidance, unless the lease is modified.

    260) Distinguishing Liabilities from Equity (Topic 480) Derivatives
    and Hedging (Topic 815). This guidance&#xA0;was intended to reduce
    the complexity associated with the issuer&#x2019;s accounting for
    certain financial instruments with characteristics of liabilities
    and equity. Specifically, the Board determined that a down round
    feature would no longer cause a freestanding equity-linked

    As previously reported, on March&#xA0;26, 2019, the Company
    commenced an action (the &#x201C;Action&#x201D;) in the Commercial
    Division of the Supreme Court for the State of New York, County of
    New York, styled as Delcath Systems, Inc., v. Iroquois Capital
    Investment Group LLC, Iroquois Master Fund Ltd., L1 Capital Global
    Opportunities Master Fund and First Fire Global Opportunities Fund
    LLC (Index No.&#xA0;651749/2019). The Action seeks expedited
    equitable relief in the form of reformation and a declaratory
    judgement to remedy a scrivener&#x2019;s error in the Series D
    Warrants issued in the Company&#x2019;s February 2018 public
    offering such that those warrants do not contain a price and
    quantity ratchet upon a sale of Company securities at a price lower
    than the offering price in the February 2018 offering. The
    defendant, L1 Capital Global Opportunities Master Fund, settled
    with the Company by exchanging its Series D Warrants for Company
    Common Stock on a <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">one-for-one</font></font> basis, which is the
    same ratio for which other investors in the February 2018 round
    exchanged their Series D Warrants in December 2018. The Company and
    the remaining defendants in the Action, Iroquois Capital Investment
    Group LLC, Iroquois Master Fund Ltd. and First Fire Global
    Opportunities Fund LLC, entered into a settlement agreement on
    April&#xA0;18, 2019, the full text of which is annexed as Exhibit
    10.42 to our Annual Report on Form <font style="WHITE-SPACE: nowrap">10-K,</font> pursuant to which such
    defendants surrendered the Series D Warrants and waived all rights
    granted to them by or in connection with the Series D Warrants and
    all rights afforded to them to participate in the Company&#x2019;s
    future Common Stock offerings. In consideration therefor, pursuant
    to the settlement agreement, (i)&#xA0;the Company paid <font style="WHITE-SPACE: nowrap">one-fifth</font> of the reasonable fees and
    expenses of defendants&#x2019; counsel incurred in connection with
    the Action and negotiation of the settlement agreement, the total
    of which shall not exceed $50,000 (the &#x201C;Settlement
    Fees&#x201D;) and (ii)&#xA0;subject to the Company securing and
    closing certain contemplated financing, the Company agreed to pay
    to the defendants $400,000 and the remaining Settlement Fees.</p>

    Company offerings granted in the September 2017 Securities Purchase
    Agreement between the Company and Hudson Bay and in the February
    2018 Securities Purchase Agreement among, inter alia, the Company

    monetary damages (which it claims to be in excess of $1 million)
    and specific performance. The Company denied any liability with
    respect to the claims set forth in the lawsuit. As previously
    reported, on January&#xA0;4, 2019, the Company was notified by its
    litigation counsel that on December&#xA0;28, 2018, the Suit was

    Basic net loss per share is determined by dividing net loss by the
    weighted average shares of common stock outstanding during the
    period, without consideration of potentially dilutive securities
    except for those shares that are issuable for little or no cash
    consideration. Diluted net loss per share is determined by dividing
    net loss by diluted weighted average shares outstanding. Diluted
    weighted average shares reflects the dilutive effect, if any, of
    potentially dilutive common shares, such as stock options and
    warrants calculated using the treasury stock method. In periods
    with reported net operating losses, all common stock options and
    warrants are generally deemed anti-dilutive such that basic net
    loss per share and diluted net loss per share are equal. However,
    in certain periods in which the exercise price of the warrants was
    less than the last reported sales price of Delcath&#x2019;s common
    stock on the final trading day of the period and there is a gain
    recorded pursuant to the change in fair value of the warrant
    derivative liability, the impact of gains related to the
    <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">mark-to-market</font></font> adjustment of
    the warrants outstanding at the end of the period is reversed and
    the treasury stock method is used to determine diluted earnings per
    share.</p>

    In April 2019, the Company entered into an exchange agreement with
    an institutional investor with respect to warrants held by such
    investor (the &#x201C;February 2018 Warrants&#x201D;). The February
    2018 Warrants were issued to several institutional investors as
    part of the Company&#x2019;s February 2018 sale of the
    Company&#x2019;s common stock and the issuance of warrants to
    purchase common shares. Pursuant to the exchange agreement, the
    Company issued 64,000 shares of the Company&#x2019;s common stock
    (the &#x201C;Exchange Shares&#x201D;) in exchange for the February
    2018 Warrants. The exchange resulted in a loss of approximately
    $6,000 which is recognized in the statement of operations.</p>

    Plan. The maximum number of shares reserved for issuance under the
    Plan is 1,500,000. Options to purchase shares of common stock are
    granted at exercise prices not less than 100% of fair value on the

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>

    The accompanying financial statements have been prepared on a going
    concern basis, which contemplates the realization of assets and the
    satisfaction of liabilities in the normal course of business. As
    shown in the accompanying financial statements during the year
    ended December&#xA0;31, 2018, the Company incurred net losses of
    $19.2&#xA0;million and used $14.7&#xA0;million of cash for its
    operating activities. These factors among others raise substantial
    doubt about the Company&#x2019;s ability to continue as a going
    concern for a reasonable period of time.</p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    The Company&#x2019;s existence is dependent upon management&#x2019;s
    ability to obtain additional funding sources or to enter into
    strategic alliances. Adequate additional financing may not be
    available to us on acceptable terms, or at all. If the Company is
    unable to raise additional capital and/or enter into strategic
    alliances when needed or on attractive terms, it would be forced to
    delay, reduce or eliminate our research and development programs or
    any commercialization efforts. There can be no assurance that the
    Company&#x2019;s efforts will result in the resolution of the
    Company&#x2019;s liquidity needs. If Delcath is not able to continue
    as a going concern, it is likely that holders of its Common Stock
    will lose all of their investment. The accompanying consolidated
    financial statements do not include any adjustments that might
    result should the Company be unable to continue as a going
    concern.</p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    The Company anticipates incurring additional losses until such
    time, if ever, that it can generate significant sales. At
    December&#xA0;31, 2018, management believed that its capital
    resources were adequate to fund operations through March 2019.
    Additional working capital will be required to continue operations.
    Operations of the Company are subject to certain risks and
    uncertainties, including, among others, uncertainty of product
    development and clinical trial results; uncertainty regarding
    regulatory approval; technological uncertainty; uncertainty
    regarding patents and proprietary rights; comprehensive government
    regulations; limited commercial manufacturing, marketing or sales
    experience; and dependence on key personnel. See Note 15 of these
    notes to the Company&#x2019;s audited consolidated financial
    statements relating to subsequent events.</p>

    The Company bases its estimates and judgments on historical
    experience and on various other assumptions that it believes are
    reasonable under the circumstances. The amounts of assets and
    liabilities reported in the Company&#x2019;s consolidated balance
    sheets and the amount of revenues and expenses reported for each of
    the periods presented are affected by estimates and assumptions,
    which are used for, but not limited to, the accounting for
    derivative instrument liabilities, stock-based compensation,
    valuation of inventory, impairment of long-lived assets, income
    taxes and operating expense accruals. Such assumptions and
    estimates are subject to change in the future as additional
    information becomes available or as circumstances are modified.
    Actual results could differ from these estimates.</p>

    Revenue is generated from proprietary and partnered product sales

    as we transfer control of the promised goods or services to our
    customers in an amount that reflects the consideration to which we
    expect to be entitled to in exchange for those goods or services.
    When obligations or contingencies remain after the products are
    shipped, such as training and certifying the treatment centers,
    revenue is deferred until the obligations or contingencies are

    from Contracts with Customers, while prior period amounts, as

    standard in 2018 were not material to our consolidated financial
    statements. In assessing our revenue arrangements in accordance
    with ASC 606, Revenue from Contracts with Customers, we must
    identify the contract, determine the transaction price including an
    estimation of any variable consideration we expect to receive in
    connection with the contract, identify the promises of goods or
    services to the customer and each distinct performance obligation,
    allocate the transaction price to each of the performance
    obligations, and recognize revenue when or as the performance
    obligations are satisfied. Each of these steps in the revenue
    recognition process requires management to make judgements and/or
    estimates. The most significant judgements and estimates involve
    the determination of variable consideration to be included in the
    transaction price. Variable consideration is recognized at an
    amount we believe is not subject to significant reversal and is
    adjusted at each reporting period if the most likely amount of
    expected consideration changes or becomes fixed. We believe this
    provides a reasonable basis for recognizing revenue, however,
    actual results could differ from estimates and significant changes
    in estimates could impact our results of operations in future
    periods.</p>

    The Company accounts for income taxes following the asset and

    Under such method, deferred tax assets and liabilities are
    recognized for the future tax consequences attributable to
    differences between the consolidated financial statement carrying
    amounts of existing assets and liabilities and their respective tax
    bases. The Company applies the accounting guidance issued to
    address the accounting for uncertain tax positions. This guidance
    clarifies the accounting for income taxes, by prescribing a minimum
    recognition threshold a tax position is required to meet before
    being recognized in the financial statements as well as provides
    guidance on derecognition, measurement, classification, interest
    and penalties, accounting in interim periods, disclosure and
    transition. The Company classifies interest and penalty expense
    related to uncertain tax positions as a component of income tax
    expense. Deferred tax assets and liabilities are measured using
    enacted tax rates expected to apply to taxable income in the years
    that the asset is expected to be recovered or the liability
    settled. A valuation allowance is provided when it is more likely
    than not that some portion or all of a deferred tax asset will not
    be realized. The ultimate realization of deferred tax assets
    depends on the generation of future taxable income during the
    period in which related temporary differences become deductible.
    The Company considers the scheduled reversal of deferred tax
    liabilities, projected future taxable income and tax planning
    strategies in its assessment of a valuation allowance. See Note 14

    entity expects to be entitled in exchange for those goods or
    services. ASU <font style="WHITE-SPACE: nowrap">2014-09</font> also
    amends the required disclosures of the nature, amount, timing and

    In June 2016, the FASB issued ASU <font style="WHITE-SPACE: nowrap">2016-15,</font> Statement of Cash Flows

    how certain transactions are classified in the statement of cash

    beginning after December&#xA0;15, 2017, and interim periods within
    those fiscal years. Early adoption was permitted, including interim
    periods within those fiscal years provided that those electing
    early adoption must adopt all of the amendments in the same period.

    In October 2016, the FASB issues ASU <font style="WHITE-SPACE: nowrap">2016-16</font> which simplifies the income

    prohibited the recognition of current and deferred income taxes for

    eliminates this prohibition for intra-entity transfers of assets

    Delcath Systems, Inc. is an interventional oncology company focused
    on the treatment of primary and metastatic liver cancers. Our
    investigational product, &#x201C;Melphalan Hydrochloride for
    Injection for use with the Delcath Hepatic Delivery System&#x201D;
    (&#x201C;Melphalan/HDS&#x201D;), is designed to administer high-dose
    chemotherapy to the liver while controlling systemic exposure and
    associated side effects.</p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    Our primary research focus is on ocular melanoma liver metastases
    (&#x201C;mOM&#x201D;) and intrahepatic cholangiocarcinoma
    (&#x201C;ICC&#x201D;) and certain other cancers that are metastatic
    to the liver. Currently there are few effective treatment options
    for certain cancers in the liver. Traditional treatment options
    include surgery, systemic chemotherapy, liver transplant, radiation
    therapy, interventional radiology techniques, and isolated hepatic
    perfusion. We believe that Melphalan/HDS and CHEMOSAT represent a
    potentially important advancement in regional therapy for primary
    liver cancer and certain other cancers metastatic to the liver and
    are uniquely positioned to treat the entire liver either as a
    standalone therapy or as a complement to other therapies.</p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    Our clinical development program for Melphalan/HDS is comprised of
    the FOCUS Clinical Trial for Patients with Hepatic Dominant Ocular
    Melanoma (the &#x201C;FOCUS Trial&#x201D;), a global registration
    clinical trial that is investigating objective response rate in
    mOM, and the ALIGN Trial, a global Phase 3 clinical trial for ICC
    (the &#x201C;ALIGN Trial&#x201D;). Our product also includes a
    registry for CHEMOSAT commercial cases performed in Europe and
    sponsorship of select Investigator Initiated Trials.</p>

    While we currently utilize third parties to manufacture some
    components of our product, we also have our own manufacturing
    operations for certain components of our product and assemble and
    package our products in Queensbury, New York. See the discussion in
    Part 1, Item 1 under the caption &#x201C;Manufacturing and Quality

    The accompanying financial statements have been prepared on a going
    concern basis, which contemplates the realization of assets and the
    satisfaction of liabilities in the normal course of business. As
    shown in the accompanying financial statements during the year
    ended December&#xA0;31, 2018, the Company incurred net losses of
    $19.2&#xA0;million and used $14.7&#xA0;million of cash for its
    operating activities. These factors among others raise substantial
    doubt about the Company&#x2019;s ability to continue as a going
    concern for a reasonable period of time.</p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    The Company&#x2019;s existence is dependent upon management&#x2019;s
    ability to obtain additional funding sources or to enter into
    strategic alliances. Adequate additional financing may not be
    available to us on acceptable terms, or at all. If the Company is
    unable to raise additional capital and/or enter into strategic
    alliances when needed or on attractive terms, it would be forced to
    delay, reduce or eliminate our research and development programs or
    any commercialization efforts. There can be no assurance that the
    Company&#x2019;s efforts will result in the resolution of the
    Company&#x2019;s liquidity needs. If Delcath is not able to continue
    as a going concern, it is likely that holders of its Common Stock
    will lose all of their investment. The accompanying consolidated
    financial statements do not include any adjustments that might
    result should the Company be unable to continue as a going
    concern.</p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    The Company anticipates incurring additional losses until such
    time, if ever, that it can generate significant sales. At
    December&#xA0;31, 2018, management believed that its capital
    resources were adequate to fund operations through March 2019.
    Additional working capital will be required to continue operations.
    Operations of the Company are subject to certain risks and
    uncertainties, including, among others, uncertainty of product
    development and clinical trial results; uncertainty regarding
    regulatory approval; technological uncertainty; uncertainty
    regarding patents and proprietary rights; comprehensive government
    regulations; limited commercial manufacturing, marketing or sales
    experience; and dependence on key personnel. See Note 15 of these
    notes to the Company&#x2019;s audited consolidated financial
    statements relating to subsequent events.</p>

    Effective the same date, the Company also amended its <font style="WHITE-SPACE: nowrap">Pre-Funded</font> Warrants such that the
    total number of June&#xA0;2018 <font style="WHITE-SPACE: nowrap">Pre-Funded</font> Warrants was increased from
    13.0&#xA0;million to 22.2&#xA0;million and the total number of July
    2018 <font style="WHITE-SPACE: nowrap">Pre-Funded</font> Warrants
    was increased from 9.2&#xA0;million to 15.8&#xA0;million. This
    amendment was accounted for as an extinguishment of debt as the
    change in cash flows exceeded 10%. The original June 2018 and July
    2018 notes were written off and the amended June 2018 and July 2018
    Notes were recorded at fair value as of the date of this amendment.
    The Company recorded $1.1&#xA0;million loss on debt extinguishment
    related to this amendment.</p>

    Delcath Systems, Inc. is an interventional oncology company focused
    on the treatment of primary and metastatic liver cancers. Our
    investigational product&#x2014;Melphalan Hydrochloride for Injection
    for use with the Delcath Hepatic Delivery System
    (&#x201C;Melphalan/HDS&#x201D;)&#x2014;is designed to administer
    high-dose chemotherapy to the liver while controlling systemic
    exposure and associated side effects. In Europe, our system is
    commercially available under the trade name Delcath Hepatic
    CHEMOSAT <sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top">&#xAE;</sup> Delivery System
    for Melphalan (&#x201C;CHEMOSAT&#x201D;), where it has been used at
    major medical centers to treat a wide range of cancers of the
    liver.</p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    Our primary research focus is on ocular melanoma liver metastases
    (&#x201C;mOM&#x201D;) and intrahepatic cholangiocarcinoma
    (&#x201C;ICC&#x201D;), a type of primary liver cancer, and certain
    other cancers that are metastatic to the liver. We believe the
    disease states we are investigating represent a multi-billion
    dollar global market opportunity and a clear unmet medical
    need.</p>

    Our clinical development program (&#x201C;CDP&#x201D;) for
    Melphalan/HDS is comprised of The FOCUS Clinical Trial for Patients
    with Hepatic Dominant Ocular Melanoma (the &#x201C;FOCUS
    Trial&#x201D;), a global registration clinical trial that is
    investigating objective response rate in mOM, and the ALIGN Trial,
    a global Phase 3 clinical trial for ICC (the &#x201C;ALIGN
    Trial&#x201D;). Our CDP also includes a registry for CHEMOSAT
    commercial cases performed in Europe and sponsorship of select

    The accompanying interim condensed consolidated financial
    statements have been prepared on a going concern basis, which
    contemplates the realization of assets and the satisfaction of
    liabilities in the normal course of business. The Company has
    incurred losses since inception and expects to continue incurring
    losses for the next several years. These losses, among other
    factors, raise substantial doubt about the Company&#x2019;s ability
    to continue as a going concern.</p>

    The Company&#x2019;s existence is dependent upon management&#x2019;s
    ability to obtain additional funding sources or to enter into
    strategic alliances. There can be no assurance that the
    Company&#x2019;s efforts will result in the resolution of the
    Company&#x2019;s liquidity needs. The accompanying statements do not
    include any adjustments that might result should the Company be
    unable to continue as a going concern.</p>

    These interim condensed consolidated financial statements are

    generally accepted accounting principles in the United States of
    America (GAAP) and with the SEC&#x2019;s instructions to Form

    The preparation of interim condensed consolidated financial
    statements requires management to make assumptions and estimates
    that impact the amounts reported. These interim condensed
    consolidated financial statements, in the opinion of management,
    reflect all adjustments, consisting of normal recurring accruals,
    necessary for a fair presentation of the Company&#x2019;s results of
    operations, financial position and cash flows for the interim
    periods ended June&#xA0;30, 2019 and 2018; however, certain
    information and footnote disclosures normally included in our
    Annual Report have been condensed or omitted as permitted by GAAP.
    It is important to note that the Company&#x2019;s results of
    operations and cash flows for interim periods are not necessarily
    indicative of the results of operations and cash flows to be
    expected for a full fiscal year or any interim period.</p>

    In February 2018, the Financial Accounting Standards Board (the
    &#x201C;FASB&#x201D;) issued Accounting Standards Update
    (&#x201C;ASU&#x201D;) <font style="WHITE-SPACE: nowrap">2018-02,</font> Income
    Statement&#x2014;Reporting Comprehensive Income (Topic 220). ASU
    <font style="WHITE-SPACE: nowrap">2018-02</font> allows a company
    to elect a reclassification from accumulated other comprehensive
    income to retained earnings for stranded tax effects resulting from
    the Tax Cuts and Jobs Act. ASU <font style="WHITE-SPACE: nowrap">2018-02</font> is effective for periods
    beginning after December&#xA0;15, 2018. Upon adoption of ASU
    <font style="WHITE-SPACE: nowrap">2018-02,</font> the Company did
    not elect to reclassify the tax effects of the Tax Cuts and Jobs
    Act from accumulated other comprehensive income to retained
    earnings, as the stranded tax effects were insignificant.</p>
    <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt">
    In February 2016, the FASB issued ASU <font style="WHITE-SPACE: nowrap">2016-02,</font> Leases (Topic 842) effective
    January&#xA0;1, 2019, electing the practical expedients and
    applying the transition provisions as of the effective date.
    Reporting periods beginning on or after January&#xA0;1, 2019 are
    presented under Topic 842, while prior period amounts, as reported
    under previous GAAP, were not adjusted. The adoption of Topic 842
    on January&#xA0;1, 2019 did not have a significant impact on the
    Company&#x2019;s consolidated results of operations or cash
    flows.</p>

    Basic net loss per share is determined by dividing net loss by the
    weighted average shares of common stock outstanding during the
    period, without consideration of potentially dilutive securities
    except for those shares that are issuable for little or no cash
    consideration. Diluted net loss per share is determined by dividing
    net loss by diluted weighted average shares outstanding. Diluted
    weighted average shares reflects the dilutive effect, if any, of
    potentially dilutive common shares, such as stock options and
    warrants calculated using the treasury stock method. In periods
    with reported net operating losses, all common stock options and
    warrants are generally deemed anti-dilutive such that basic net
    loss per share and diluted net loss per share are equal. However,
    in certain periods in which the exercise price of the warrants was
    less than the last reported sales price of Delcath&#x2019;s common
    stock on the final trading day of the period and there is a gain

    The Company recognizes <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">right-of-use</font></font>
    (&#x201C;ROU&#x201D;) assets and lease liabilities when it obtains
    the right to control an asset under a leasing arrangement with an
    initial term greater than twelve months. The Company leases its
    facilities under <font style="WHITE-SPACE: nowrap">non-cancellable</font> operating and

    The Company evaluates the nature of each lease at the inception of
    an arrangement to determine whether it is an operating or financing
    lease and recognizes the ROU asset and lease liabilities based on
    the present value of future minimum lease payments over the
    expected lease term. The Company&#x2019;s leases do not generally
    contain an implicit interest rate and therefore the Company uses
    the incremental borrowing rate it would expect to pay to borrow on
    a similar collateralized basis over a similar term in order to
    determine the present value of its lease payments.</p>

    On June&#xA0;6, 2019, the Company entered into an agreement with
    two institutional investors, pursuant to which the investors agreed
    to transfer and surrender to the Company for cancellation of
    warrants to purchase 3.9&#xA0;million shares of the Company&#x2019;s
    common stock (the &#x201C;Series D Warrants&#x201D;) and warrants to

    stock (the <font style="WHITE-SPACE: nowrap">&#x201C;Pre-Funded</font> Series D
    Warrants&#x201D;). Under the terms of the Purchase Agreement, the
    investors agreed to defer the payment of the purchase price for the
    Series D Warrants and <font style="WHITE-SPACE: nowrap">Pre-Funded</font> Series D Warrants and,
    accordingly, the Company agreed to sell and issue to the investors
    8% Senior Secured Promissory Notes in an aggregate principal amount
    of $2&#xA0;million in full payment and satisfaction of the purchase
    price for the Series D Warrants and <font style="WHITE-SPACE: nowrap">Pre-Funded</font> Series D Warrants. This
    agreement was effective upon the closing of the Company&#x2019;s

    On July&#xA0;11, 2019 and August&#xA0;15, 2019, the Company and certain accredited investors
    entered into securities purchase agreements (the &#x201C;Securities Purchase Agreements&#x201D;) pursuant to which the
    Company sold to investors an aggregate of 20,000 shares of Series E
    Convertible Preferred Stock, par value $0.01 per share and 9,510 shares of Series E-1 Convertible Preferred Stock,
    par value $0.01 per share, having the rights and privileges described in the
    Company&#x2019;s certificate of designations for such Series E Convertible Preferred Stock and Series E-1 Convertible Preferred Stock,
    at a price of $1,000 per share.
    Pursuant to the Securities Purchase Agreements,
    the Company also issued to each Investor a warrant (a &#x201C;2019 Warrant&#x201D;) to purchase a
    number of shares of common stock of the Company, equal to the
    number of shares of common stock issuable upon conversion of the
    Series E Preferred Stock purchased by the investor. Each 2019 Warrant has an exercise
    price of $0.06, subject to adjustment in accordance with the terms
    of the 2019 Warrants (the &#x201C;Exercise Price&#x201D;), and is exercisable at any time beginning on
  the date that the Company effects a reverse stock split until 5:00
  p.m. (NYC time) on the fifth anniversary of the date of the reverse
  stock split. The Company received gross proceeds from the private
  placements of $29.5&#xA0;million, before deducting cash fees in the
    amount of $2.2&#xA0;million payable to Roth Capital Partners, LLC
    (&#x201C;Roth&#x201D;) for serving as placement agent and cash fees
    in the amount of $0.6&#xA0;million payable to Roth for serving as

    As previously reported, in January&#xA0;2019, the Company
    terminated Backstop Commitment Purchase Agreements with four
    institutional investors, by their mutual agreement. The Company and
    such institutional investors entered into Backstop Commitment
    Purchase Agreements in connection with a rights offering conducted
    by the Company that closed in September 2018 in which the Company
    proposed to raise up to $50&#xA0;million by distributing, at no
    charge, to holders of its Common Stock <font style="WHITE-SPACE: nowrap">non-transferable</font> rights to subscribe
    for and purchase shares of the Company&#x2019;s Common Stock at a
    price of $1.75 per share (the &#x201C;Subscription Price&#x201D;).
    Pursuant to the Backstop Commitment Purchase Agreements, such
    institutional investors agreed to purchase, at the Subscription
    Price, shares not issued in the rights offering following the
    expiration of the rights offering subscription period, subject to
    certain conditions, including the requirement that the closing
    price of a share of the Company&#x2019;s Common Stock as reported by
    the OTCQB or higher market for each of the five business days
    immediately preceding a purchase exceeded the Subscription Price.
    The Backstop Commitment Purchase Agreements were terminated by
    mutual agreement of the parties thereto due to the fact that the
    closing price of the Company&#x2019;s Common Stock had not exceeded
    the Subscription Price since October&#xA0;1, 2018 and, thus, the
    institutional investors had no obligation to purchase shares.</p>

    On March&#xA0;29, 2019, the Company exchanged all of its Series D
    Preferred Stock (with a stated value of $1,160,000) and received
    $400,000 in proceeds and issued a senior secured promissory note to
    an investor with a principal amount of $1,560,000. The note is due
    on April&#xA0;1, 2020, bears interest at 8% per annum and is
    nonconvertible.</p>

    $3.3&#xA0;million from two institutional investors and issued
    promissory notes to the investors. The promissory notes have an
    aggregate principal amount of $3.3&#xA0;million, bear interest at
    the rate of 8% per annum and are due six months from the issuance
    of each note. The promissory notes are nonconvertible. The notes
    contain standard events of default and remedies therefor. The
    Company&#x2019;s obligations under the promissory notes to the
    institutional investor are secured by a lien on the Company&#x2019;s
    assets.</p>
