Our lead product candidate, the HEPZATO<div style="font-size: 85%; vertical-align: top;;display:inline;;font-size:9.4px">&#8482;</div> KIT (melphalan hydrochloride for injection/hepatic delivery system), or HEPZATO, is a drug/device combination product. HEPZATO is designed to administer high-dose chemotherapy to the liver while controlling systemic exposure and associated side effects. In Europe, our commercial product is a stand-alone medical device having the same device components as the HEZPATO but without the melphalan hydrochloride, is designated as a Class&#160;III medical device, and is approved for sale under the trade name CHEMOSAT<div style="font-size: 85%; vertical-align: top;;display:inline;;font-size:9.4px">&#174;</div> Hepatic Delivery System for Melphalan, or CHEMOSAT, where it has been used at major medical centers to treat a wide range of cancers of the liver. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">In the United States, HEPZATO is considered a combination drug and device product regulated by the United&#160;States Food and Drug Administration, or the FDA. Primary jurisdiction for regulation of HEPZATO has been assigned to the FDA&#8217;s Center for Drug Evaluation and Research. The FDA has granted Delcath six orphan drug designations (five for melphalan in ocular melanoma, cutaneous melanoma, cholangiocarcinoma, hepatocellular carcinoma, and neuroendocrine tumor indications and one for doxorubicin in the hepatocellular carcinoma indication). HEPZATO has not been approved for sale in the United States. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">In December 2010, the Company submitted a new drug application, or NDA, to the FDA seeking the approval of its first generation melphalan hydrochloride for injection/hepatic delivery system. In response, in February 2011, the FDA issued a <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">Refusal-to-File</div></div> letter. The Company responded to the FDA&#8217;s letter and updated its delivery system, including modifications to the system&#8217;s filter. In September 2013, the FDA issued a Complete Response Letter, or CRL, to the Company&#8217;s NDA requesting, among other things, that the Company perform an adequate and well controlled study utilizing its updated delivery system. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">In response to the CRL, in 2016, the Company began enrolling patients in the FOCUS Clinical Trial for Patients with Hepatic Dominant Ocular Melanoma (the &#8220;FOCUS Trial&#8221;), a global registration clinical trial studying HEPZATO&#8217;s safety and efficacy treating metastatic ocular melanoma, or mOM. The FOCUS Study was originally designed as a randomized controlled trial comparing HEPZATO versus the Best Alternative Care (BAC) with a primary endpoint of overall survival. Due to significant challenges enrolling patients into the Trial, including the fact that the BAC arm was known to have limited efficacy and the availability of CHEMOSAT in Europe, in 2018, the Company and FDA agreed to amend the FOCUS Trial to a <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">single-arm,</div> nonrandomized trial with a primary endpoint of Overall Response Rate (ORR) and a secondary endpoint of Duration of Response (DOR). The last patient in the FOCUS trial was treated in May 2021 and, per the Study&#8217;s statistical plan, a final predefined exploratory survival analysis, versus the Best Alternative Care (BAC), will be conducted twenty-four months from the date of the last patient treated. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">In December 2021, the Company announced that HEPZATO met its prespecified endpoint. Based on the FOCUS Trial results, the Company is preparing to file a revised NDA for HEPZATO. Depending on feedback from FDA, we hope to file the revised NDA by <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">mid-2022.</div> </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">CHEMOSAT is available in select markets in the United Kingdom and the European Union. In December 2018, we entered into a license agreement with medac GmbH, for the commercialization of CHEMOSAT in Europe. The license agreement has been terminated and, as of March 1, 2022, we have begun directly marketing CHEMOSAT in these markets. In addition, on February&#160;28, 2022, CHEMOSAT received Medical Device Regulation (MDR) certification under the European Medical Devices Regulation [2017/745/EU]. </div></div> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">4 </div></div> </div> </div> <div style="margin-top: 1em; margin-bottom: 0em; page-break-before: always;"></div> <hr style="width: 100%; height: 3px; color: rgb(153, 153, 153);"/> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">In addition to HEPZATO&#8217;s use to treat mOM, we believe that HEPZATO has the potential to treat other liver dominant cancers, such as Metastatic Colorectal Cancer and Cholangiocarcinoma, and plan to begin the study of HEPZATO to treat such conditions in the near future. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Cancers in the Liver&#8212;A Significant Unmet Need </div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">According to the American Cancer Society&#8217;s, or ACS<div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">, Cancer Facts</div></div><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">&#160;&amp; Figures 2022</div></div> report, cancer is the second leading cause of death in the United States, with an estimated 609,360 deaths and over 1.9&#160;million new cases expected to be diagnosed in 2022. Cancer is one of the leading causes of death worldwide, accounting for approximately 10&#160;million deaths and 19.3&#160;million new cases in 2020 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 2018 was $112.5&#160;billion. The liver is often the life-limiting organ for cancer patients and cancer that spreads to the liver is one of the leading causes of cancer death. Cancer that begins in one area of the body often metastasizes to the liver. Patient prognosis is generally poor once cancer has spread to the liver. Consequently, cancers of the liver remain a major unmet medical need globally. </div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Liver Cancers&#8212;Incidence and Mortality </div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">Cancers of the liver consist of primary liver cancer and metastatic liver cancer. Primary liver cancers (hepatocellular carcinoma, or HCC, and Intrahepatic Cholangiocarcinoma 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 <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">hepatitis-B,</div> <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">hepatitis-C,</div> high levels of alcohol consumption, aflatoxin, cigarette smoking and exposure to industrial pollutants, are present. Metastatic liver cancer, also called liver metastasis, or secondary liver cancer, results from the spread or &#8220;metastases&#8221; of a primary cancer into the liver. 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. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The liver is a difficult organ to treat for certain cancers. Current liver treatment options include surgery, systemic drugs, and minimally invasive or liver directed options.&#160;Surgery options include surgical resections, liver transplants, and isolated hepatic perfusion.&#160;Systemic options include systemic chemotherapy and immunotherapy. Minimally invasive options include external beam radiation therapy and liver directed procedures.&#160;Liver directed (interventional oncology) procedures in the liver are performed by an interventional radiologist.&#160;These procedures include trans-arterial chemoembolization (TACE, DEBTACE) and Radioembolization (SIRT, TARE, or Y90).&#160;We believe that CHEMOSAT and HEPZATO, if approved in the United States, represent an important advancement in regional therapy for liver directed treatment of 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. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Ocular Melanoma </div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">Ocular melanoma frequently metastasizes to the liver. Based on third party research that we commissioned in 2018, approximately <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">5,000-6,200</div> cases of ocular melanoma are diagnosed in the United States and Europe annually, and approximately 50% of these patients will develop metastatic disease. Of metastatic cases of ocular melanoma, approximately 90% of patients develop liver involvement.

This &#8220;whole organ&#8221; 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&#8217;s circulatory system. During the procedure, known as percutaneous hepatic perfusion, PHP<div style="font-size: 85%; vertical-align: top;;display:inline;;font-size:9.4px">&#174;</div>, or PHP therapy, three catheters are placed percutaneously through standard interventional radiology techniques. The catheters temporarily isolate the liver from the body&#8217;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 adsorb 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&#8217;s circulatory system. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">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 HEPZATO 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.

A significant portion of FDA&#8217;s presentation to the ODAC panel was focused on the FDA&#8217;s assessment of treatment-related risks, including the analysis of treatment-related deaths that occurred during clinical trials. The FDA also expressed concerns about hypotension, or low blood pressure, during the procedure, length of hospital stay, as well as risks of stroke, heart attack, renal failure, and bone marrow suppression. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">In September 2013, the FDA issued a complete response letter, or CRL, relating to our NDA. The FDA issues a CRL after the review of an NDA has been completed and questions remain that preclude approval of the NDA in its current form. The deficiencies identified in the CRL included, among other items, the requirement that we conduct an adequate and well-controlled study demonstrating substantial evidence that the effectiveness of the kit the Company intended to market outweighed its risks. The CRL also required that we address certain clinical, clinical pharmacology, human factors and product quality elements. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">In January 2016, we entered into a Special Protocol Assessment agreement, or SPA, with the FDA on the design of a new Phase 3 clinical trial of HEPZATO to treat patients with hepatic dominant ocular melanoma. This SPA represented an agreement with the FDA that a specific Phase 3 trial would adequately address objectives that, if met, would support the submission for regulatory approval of HEPZATO. The SPA&#8217;s primary endpoint was overall survival, and secondary endpoints included progression-free survival, overall response rate and <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">quality-of-life</div></div> measures. However, the Company faced significant difficulties, including the fact that the Best Alternative Care (BAC) arm was known to have limited efficacy, enrolling patients into the study under the SPA. Therefore, in the summer of 2018, we amended the protocol for the trial to a <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-randomized,</div> <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">single-arm</div> study with a different primary endpoint (objective response rate), which terminated the SPA. </div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Clinical Development Program </div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The focus of our clinical development program is to generate clinical data for CHEMOSAT and HEPZATO in various disease states to demonstrate efficacy and validate the safety profile of the current version of the product and treatment procedure. We believe that the improvements we have made to CHEMOSAT and HEPZATO and to the PHP therapy have addressed the adverse event profile and procedure-related risks that led to the issuance of the CRL.

With 81 patients and 250 procedures this is the largest single center percutaneous hepatic perfusion study to date. The study titled<div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;"> Chemosaturation with Percutaneous Hepatic Perfusion for Metastatic Uveal Melanoma</div></div>, by Sachin&#160;Modi, MD FRCR(IR), et al, evaluated the safety and efficacy of PHP therapy in 81 patients with unresectable liver dominant metastases from ocular melanoma treated with CHEMOSAT. 50.6% of patients had prior treatments for metastatic uveal melanoma. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Average time from diagnosis of liver metastasis to first PHP was 5.3 months (158 days). The 81 patients underwent a total of 250 PHP treatments. The median number of treatments per patient was three. Tumor response was evaluated using Response Evaluation Criteria in Solid Tumors and adverse events&#160;were evaluated using Common Criteria for Adverse Events. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Results of the study in the 81 evaluable patients showed that 7 patients (8.6%) had a complete response, 42 patients (51.9%) had a partial response, 16 patients (19.8%) had stable disease, and 16 patients (19.8%) had progressive disease for a disease control rate of 80.2%. Median progression free survival (PFS) after the first treatment was 8.4 months. Median overall survival (OS) was 14.9 months. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Safety analysis showed that in 23 patients there were a total of 43 grade 3 (29) or grade 4 (14) treatment-related adverse events. There were no grade 5 treatment-related adverse events. Investigators concluded that PHP provides excellent response rates for patients and side effects are reduced with treatment team experience. </div></div> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">9 </div></div> </div> </div> <div style="margin-top: 1em; margin-bottom: 0em; page-break-before: always;"></div> <hr style="width: 100%; height: 3px; color: rgb(153, 153, 153);"/> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Market Access and Commercial Clinical Adoption </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Europe </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Since launching CHEMOSAT in Europe, over 1,200 commercial treatments have been performed at over 25 European cancer centers. Physicians in Europe have used CHEMOSAT to treat patients with a variety of cancers in the liver, primarily ocular melanoma liver metastases, and other tumor types, including cutaneous melanoma, hepatocellular carcinoma, cholangiocarcinoma, and liver metastases from colorectal cancer, breast, pancreatic and neuroendocrine. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">In December 2018, the Company&#8217;s wholly-owned subsidiary, Delcath Systems Ltd., entered into a license agreement with medac GmbH, for the commercialization of CHEMOSAT in Europe. The medac license provided to medac the exclusive right to market and sell CHEMOSAT in all member states of the EU, Norway, Liechtenstein, Switzerland, and the United Kingdom. The medac license provided to Delcath a combination of upfront and success-based milestone payments as well as a fixed transfer price per unit of CHEMOSAT and specified royalties. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">In April 2021, we issued medac an invoice for &#8364;1&#160;million for a milestone payment under the license agreement. medac disputed the invoice and, in response, on October&#160;12, 2021, we notified medac that we were terminating the license agreement effective April&#160;12, 2022. In response to medac&#8217;s continued failure to pay the milestone and its demand for us to withdraw the termination notice, on December&#160;16, 2021, we initiated an arbitration proceeding pursuant to the license agreement&#8217;s dispute resolution procedures. On December&#160;30, 2021, we received a letter from medac stating that, due to our failure to withdraw the termination notice, medac was terminating the license agreement with immediate effect. In the letter, medac reserved its rights in full, including a purported claim for damages for wrongful termination. In a separate letter, medac agreed to work with us to arrange an orderly transition in order to minimize the impact of any termination on patients and physicians. As of March&#160;1, 2022, this transition has been completed and we have assumed direct responsibility for sales, marketing and distribution of CHEMOSAT in Europe. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The arbitration proceeding is moving forward with the parties agreeing to stay the arbitration for a finite period to pursue settlement discussions. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">European Reimbursement </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">A critical driver of utilization growth for CHEMOSAT in Europe is the expansion of reimbursement mechanisms for the procedure in our priority markets. In most European countries, the government provides healthcare and controls reimbursement levels. Since the EU has no jurisdiction over patient reimbursement or pricing matters in its member states, the methodologies for determining reimbursement rates and the actual rates may vary by country.&#160;Reimbursement is administered on a regional and national basis. Medical devices are typically reimbursed under Diagnosis Related Groups, or DRG, as part of a procedure. Prior to obtaining permanent DRG reimbursement codes, in certain jurisdictions, we are actively seeking interim reimbursement from existing mechanisms that include specific interim reimbursement schemes, new technology payment programs as well as existing DRG codes. Currently we have an interim level of reimbursement in Germany. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">In addition, on February 28, 2022, CHEMOSAT received Medical Device Regulation certification under the European Medical Devices Regulation [2017/745/EU], which may be considered by jurisdictions when evaluating reimbursement. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">The release of the clinical study report from the FOCUS Trial later this year, will create the opportunity to apply for National Level reimbursement in each European country in regard to metastatic Ocular Melanoma (mOM). These applications must be made by us on a <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">country-by-country</div></div> level basis, with priority placed on markets where CHEMOSAT is currently used. The results from the Focus Trial should also support existing reimbursement mechanisms, such as Germany, allowing more hospital centers to secure funding to utilize CHEMOSAT. This increased level of evidence will ultimately support securing full funding for the treatment under DRG codes. </div> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">10 </div></div> </div> </div> <div style="margin-top: 1em; margin-bottom: 0em; page-break-before: always;"></div> <hr style="width: 100%; height: 3px; color: rgb(153, 153, 153);"/> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; text-indent: 0px;"></div> </div> </div> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">As of March&#160;1, 2022, reimbursement applications in priority European markets will be handled directly by the Company.

Foreign regulatory agencies, the FDA and comparable regulatory agencies in state and local jurisdictions impose extensive requirements upon the clinical development, <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">pre-market</div> clearance and approval, manufacturing, labeling, marketing, advertising and promotion, pricing, storage, and distribution of pharmaceutical and medical device products. Failure to comply with applicable foreign regulatory agency or FDA requirements may result in Warning Letters, fines, civil or criminal penalties, suspension, or delays in clinical development, recall or seizure of products, partial or total suspension of production or withdrawal of a product from the market. </div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">United States Regulatory Environment </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;">In the United States, the FDA regulates drug and device products under the FDCA, and its implementing regulations. HEPZATO is subject to regulation as a combination product, which means it is composed of both a drug product and 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 jurisdiction over its <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">pre-market</div> review and regulation based on a determination of its primary mode of action, which is the single mode of action that provides the most important therapeutic action. In the case of HEPZATO, the primary mode of action is attributable to the drug component of the product, which means that the Center for Drug Evaluation and Research, has primary jurisdiction over its <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">pre-market</div> development and review. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The process required by the FDA before drug product candidates may be marketed in the United States generally involves the following: </div></div> <div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div>

In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. IND submissions may not result in FDA authorization to commence a clinical trial. A separate submission to an existing IND must also be made for each successive clinical trial conducted during product development. Further, an independent institutional review board, or IRB, for each medical center proposing to conduct the clinical trial must review and approve the plan for any clinical trial before it commences at that center, and it must monitor the study until completed. The FDA, the IRB or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects or patients are being exposed to an unacceptable health risk. Clinical testing also must satisfy extensive good clinical practice regulations and regulations for informed consent and privacy of individually identifiable information. Similar requirements to the United States IND are required in the EU and other jurisdictions in which we may conduct clinical trials. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Clinical Trials </div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">For purposes of NDA submission and approval, clinical trials are typically conducted in the following sequential phases, which may overlap: </div></div> <div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div>

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 Oncology Drug Advisory Committee, 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, or 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 the applicant or its collaborators interpret data. Approval may be contingent on a Risk Evaluation and Mitigation Strategy, or 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. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">There are three primary regulatory pathways for a New Drug Application under Section&#160;505 of the FDCA: Section&#160;505 (b)(1), Section&#160;505 (b)(2) and Section&#160;505(j).&#160;A Section&#160;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&#160;505 (b)(2) application is used for a new drug that relies on data not developed by the applicant. Section&#160;505(b)(2) of the FDCA 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&#8217;s findings of safety and effectiveness for previously approved products. Section&#160;505(j) application, also known as an abbreviated NDA, is used for a generic version of a drug that has already been approved. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Orphan Drug Exclusivity </div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Some jurisdictions, including the United States, may designate drugs for relatively small patient populations as orphan drugs. Pursuant to the U.S. 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. </div></div> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">13 </div></div> </div> </div> <div style="margin-top: 1em; margin-bottom: 0em; page-break-before: always;"></div> <hr style="width: 100%; height: 3px; color: rgb(153, 153, 153);"/> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We have received five&#160;orphan drug designations for melphalan in the following indications: </div></div> <div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div>

Adverse event experience with the product must be reported to the FDA in a timely fashion and pharmacovigilance programs to proactively look for these adverse events are mandated by the FDA. Drug manufacturers and their subcontractors must 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 drug manufacturers.&#160;Following such inspections, the FDA may issue notices on Form 483 and Untitled Letters or Warning Letters that could require the drug manufacturer to modify certain activities. A 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 drug manufacturer to possible legal or regulatory action, such as suspension of manufacturing, seizure of product, injunctive action or possible civil penalties.

The EU is composed of the 27 Member States of the EU plus Norway, Iceland, and Liechtenstein. Under the EU Medical Device Directive (Directive No 93/42/EEC of 14&#160;June 1993), as last amended, drug delivery products such as the CHEMOSAT system are governed by the EU laws on pharmaceutical products only if they are (i)&#160;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)&#160;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 Device 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 EU market as a single integral unit with melphalan, the product has been governed solely by the EU Medical Device 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. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">In order to commercialize a medical device in the EU, we must comply with the essential requirements of the EU Medical Device Directive and more recently, the EU Medical Device Regulation. Compliance with these requirements entitles a manufacturer to affix a CE conformity mark, without which the products cannot be commercialized in the EU. 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. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">The EU Medical Device Directive establishes a classification system placing devices into Class&#160;I, IIa, IIb, or III, depending on the risks and characteristics of the medical device. For certain types of <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">low-risk</div> medical devices (i.e., Class&#160;I devices which are <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-sterile</div> 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 Device 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 EU to conduct conformity assessments. Under the EU Medical Device Directive, CHEMOSAT has been regulated as a Class&#160;IIb medical device and, as such, the Notified Body was not required to carry out an examination of the product&#8217;s design dossier as part of its conformity assessment prior to commercialization. The Company must comply with the essential requirements of the EU Medical Device Directive and, more recently, the EU Medical Device Regulation, and is subject to a conformity assessment procedure requiring the intervention of a Notified Body. The conformity assessment procedure for Class&#160;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 EU Medical Device Directive. If the Notified Body&#8217;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. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">A manufacturer without a registered place of business in a Member State of the EU that places a medical device on the market under its own name must designate an authorized representative established in the EU who can act </div></div> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">15 </div></div> </div> </div> <div style="margin-top: 1em; margin-bottom: 0em; page-break-before: always;"></div> <hr style="width: 100%; height: 3px; color: rgb(153, 153, 153);"/> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; text-indent: 0px;"></div> </div> </div> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">before, and be addressed by, a Competent Authority on the manufacturer&#8217;s behalf with regard to the manufacturer&#8217;s obligations under the EU Medical Device Directive and, more recently, the EU Medical Device Regulation.

This new EU Medical Device Regulation became effective on May&#160;25, 2017, marking the start of a <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">3-year</div> transition period for manufacturers selling medical device in Europe to comply with the new EU Medical Device Regulation, which governs all facets of medical devices. The transition task is highly complex and touches every aspect of product development, manufacturing production, distribution and post marketing evaluation. Due to COVID-related delays experienced by the medical device industry and Notified Bodies (NB) alike, on April&#160;17, 2020, the European Parliament adopted the European Commission&#8217;s proposal to postpone the implementation of the EU Medical Device Regulation (EU) 2017/745 by 12 months or until May&#160;26, 2021. Delcath did not achieve EU Medical Device Regulation certification by that date due to COVID-related delays; however, our CE Mark under the EU Medical Device Directive remained effective and allowed us to fully operate in Europe. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">On February&#160;28, 2022, CHEMOSAT received medical device certification under the new EU Medical Device Regulation, which replaced CHEMOSAT&#8217;s prior certification under the EU Medical Device Directive. Achieving EU Medical Device Regulation certification entails a detailed evaluation from a designated EU Notified Body, including an audit of quality systems and a review of documentation supporting safety and performance claims for the device. The EU Medical Device Regulation greatly expands upon existing EU Medical Device Directive requirements, including the level of clinical evidence supporting claims, post-marketing surveillance, database traceability, unique device identification (UDI) and increased supply chain oversight. Under the EU Medical Device Regulation, CHEMOSAT&#8217;s designation has changed from a Class&#160;IIb to a Class&#160;III medical device. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">In the EU, 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, user or 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&#8217;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, or 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. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The manufacturer or its authorized representative must notify its customers and/or the end users of the medical device of the FSCA via a Field Safety Notice. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">In the EU, the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">off-label</div> promotion of a pharmaceutical product is strictly prohibited under the EU Community Code on Medicinal Products, which provides that all information provided within the context of the promotion of a drug must comply with the information contained in its approved summary of product characteristics.

We intend to seek extension for one of our patents after FDA approval if it has not expired prior to the date of approval. In addition to our proprietary protections, the FDA has granted us six orphan drug designations that provide us a seven-year period of exclusive marketing beginning on the date that our NDA is approved by the FDA for the designated orphan drug. While the exclusivity only applies to the indication for which the drug has been approved, we believe that this exclusivity will provide us with added protection once commercialization of an orphan drug designated product begins. There has been and continues to be substantial litigation regarding patent and other intellectual property rights in the pharmaceutical and medical device areas. If a third party asserts a claim against us, we may be forced to expend significant time and money defending such actions and an adverse determination in any patent litigation could subject us to significant liabilities to third parties, require us to redesign our product, require us to seek licenses from third parties and, if licenses are not available, prevent us from manufacturing, selling, or using our product.&#160;Additionally, we plan to enforce our intellectual property rights vigorously and may find it necessary to initiate litigation to enforce our patent rights or to protect our trade secrets or <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">know-how.</div> Patent litigation can be costly and time consuming and there can be no assurance that the outcome will be favorable to us. </div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Competition </div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The healthcare industry is characterized by extensive research, rapid technological progress and significant competition from numerous healthcare companies and academic institutions. Competition in the cancer treatment industry is intense. We believe that the primary competitive factors for products addressing cancer include safety, efficacy, ease of use, reliability, price, and patient&#8217;s quality of life. We also believe that physician relationships, especially relationships with leaders in the medical, surgical, and oncology communities, are important competitive factors.

In response to the pandemic, hospitals participating in the trials in affected countries have taken a number of actions, including restricting elective and other procedures that are not deemed to be life-threatening, suspending clinical trial activities and limiting access to data monitoring. As a result, patients enrolled in our clinical trials have had the start of their treatments postponed and ongoing treatment regimens may be delayed. In addition, we do not have sufficient access to monitor trial data on a timely basis. These restrictions have had a materially adverse effect on our clinical operations. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">The extent to which the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19</div> pandemic may affect our clinical trial operations will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the duration of the outbreak, the spread and severity of new variants of <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19,</div> and the effectiveness of governmental actions in response to the pandemic. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">We expect that actions taken in response to the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19</div> pandemic will also materially and adversely affect sales of CHEMOSAT. As noted above, some hospitals are restricting procedures that are not deemed to be life-threatening at this time.

In addition, the notes to our financial statements for the year ended December&#160;31, 2021, included in this Annual Report on Form <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">10-K,</div> contain a disclosure describing the existence of conditions that raise substantial doubt about our ability to continue as a going concern. Our ability to continue as a going concern 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 we are unable to raise additional capital and/or enter into strategic alliances when needed or on attractive terms, we would be forced to delay, reduce, or eliminate our research and development programs or any commercialization efforts.

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. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">In response to our NDA, which we submitted to the FDA in August 2012 seeking approval for use of our HEPZATO Kit for the treatment of patients with ocular melanoma of the liver, in September 2013, the FDA denied approval of the NDA in its then current form and issued a complete response letter, or 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 we must perform additional &#8220;well-controlled randomized trial(s) to establish the safety and efficacy of HEPZATO Kit using overall survival as the primary efficacy outcome measure&#8221; and which &#8220;demonstrates that the clinical benefits of HEPZATO Kit outweigh its risks.&#8221; The FDA also required that the additional clinical trial(s) be conducted using the product we intend to market. Prior to conducting additional clinical trials, we were required to satisfy certain other requirements of the CRL, including, but not limited to, product quality testing, <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">pre-clinical</div> studies and human factors validation information.</div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">We have initiated a pivotal Phase 3 trial in ocular melanoma metastases. We had a SPA agreement with the 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 <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-randomized,</div> <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">single-arm</div> study with a primary endpoint of objective response rate. Although the changes to the protocol invalidated the SPA agreement, the FDA stated that it would not object to our conducting a study outside of a SPA agreement. However, we 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 HEPZATO. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">In addition, we conduct and participate in numerous clinical trials with a variety of study designs, patient populations and trial endpoints to support additional indications for HEPZATO with other drug therapies.

In 2015, the Phase 2 clinical trial for HCC was expanded to include a cohort of patients with intrahepatic cholangiocarcinoma, a type of primary liver cancer, or ICC. 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&#8217;s perception of these clinical data or FDA&#8217;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 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. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">The Company does not expect to generate significant revenue for the foreseeable future. </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Our entire focus has been on developing, commercializing, and obtaining regulatory authorizations and approvals of CHEMOSAT and HEPZATO and we have only developed these products for the treatment of cancers in the liver. If CHEMOSAT and HEPZATO for the treatment of cancers in the liver fail as commercial products, we have no other products to sell. In addition, since CHEMOSAT currently is approved for commercialization solely in the European Union, or the EU, and limited other jurisdictions (including the United Kingdom), if we are unsuccessful in commercializing the product in the EU and/or if HEPZATO is not approved in the United States and elsewhere, we will have no means of generating revenue. Accordingly, we may not generate material 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 unless and until our product candidates are approved by the FDA or other additional foreign regulatory agencies and successfully marketed. CHEMOSAT and HEPZATO 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. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Continuing losses may exhaust our capital resources. </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">As of December&#160;31, 2021, we had $27.0&#160;million in cash and cash equivalents. We have had minimal revenue to date, and have a substantial accumulated deficit, recurring operating losses and negative cash flow. For the years ended December&#160;31, 2021 and 2020, we incurred net losses of approximately $25.6&#160;million and $24.2&#160;million, respectively and expect to continue to incur losses in 2022. To date, we have funded operations through a combination of private placements and public offerings of our securities, including convertible notes. If we continue to incur losses, we may exhaust our capital resources, and as a result may be unable to complete our clinical trials, engage in product development and the regulatory approval process and commercialization of CHEMOSAT and HEPZATO or any other versions of these products. If we are unable to raise capital or generate sufficient revenue, we may not be able to pay our debts when they become due and may have to seek protection under federal bankruptcy law or enter into a receivership. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">If we cannot raise additional capital, our potential to generate future revenues will be significantly limited since we may not be able to further commercialize CHEMOSAT and HEPZATO, complete our clinical trials or conduct future product development and clinical trials. </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We will require additional substantial financing to complete our clinical trial program or seek other approvals, to conduct future development and clinical trials and to further commercialize our product in the EU and any other markets where we may receive approval for our products.

We do not know if additional financing will be available when needed at all or on acceptable terms.

If physicians are unwilling to obtain melphalan separately for use with CHEMOSAT, our ability to commercialize CHEMOSAT in the EU will be significantly limited. Our product instructions and indication reference the chemotherapeutic agent melphalan. However, no melphalan labels in the EU reference our product, and the labels vary from country to country with respect to the approved indication of the drug and its mode of administration. As a result, the delivery of melphalan with our device may not be within the applicable label with respect to some indications in some Member States of the EU where the drugs are authorized for marketing. Physicians intending to use CHEMOSAT must obtain melphalan separately for use with CHEMOSAT and must use melphalan independently at their discretion.

In order to maintain the right to affix the CE Mark in the EU, we are subject to compliance obligations, and any material changes to the approved product, such as manufacturing changes, product improvements or revised labeling, may require further regulatory review. Additionally, we are subject to ongoing audits by the European Notified Body, and the right to affix the CE Mark to the Generation Two version of CHEMOSAT may be withdrawn for a number of reasons, including the later discovery of previously unknown problems with the product. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">To the extent that HEPZATO is approved by the FDA or CHEMOSAT by any other regulatory agency, we will be subject to similar ongoing regulatory obligations and oversight in those countries where approval is obtained.

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, or cGMPs, good clinical practices, or GCPs, and good laboratory practices, which are regulations and guidelines enforced by the FDA for all products in clinical development, for any <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">pre-clinical</div> or clinical trials that we conduct post-approval. In addition, post-marketing requirements for HEPZATO may include implementation of a risk evaluation and mitigation strategies, or REMS, program to ensure that the benefits of the product outweigh its risks. A typical REMS may include a medication guide, a patient package insert, a communication plan to healthcare professionals, restrictions on distribution or use and/or other elements to assure safe use of the product. However, our discussions with the FDA have indicated that a medication guide or communication plan will not be required. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things: </div></div> <div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div>

Although melphalan and other drugs have been approved by the FDA for use as chemotherapeutic agents, regulatory approval is required in the United States for the combined medical device component and drug component and the specific indication, dose and route of administration of melphalan or other chemotherapeutic agents or compounds used in our system. We are seeking approval of HEPZATO for a substantially higher dose of melphalan than prior approved doses of melphalan and such other chemotherapeutic agents or other compounds. We must obtain separate regulatory approvals for HEPZATO with melphalan, and every other chemotherapeutic agent or other compound used with the system that we intend to market, and all the manufacturing facilities used to manufacture components or assemble our system must be inspected and meet legal requirements.

Clinical development is a long, expensive and uncertain process and is subject to delays. We may encounter delays or rejections for various reasons. Moreover, approval policies or regulations may change.

In September 2013, the FDA issued a CRL indicating that we must perform additional well-controlled randomized trial(s) to establish the safety and efficacy of HEPZATO using overall survival as the primary efficacy outcome measure and which demonstrates that the clinical benefits of HEPZATO outweigh its risks. Our current Phase 3 trial in ocular melanoma liver metastases, the FOCUS Trial, is not randomized and&#160;uses a different primary efficacy outcome measure. The FDA has stated that it would not object to our conducting a study outside of a SPA agreement.

Drugs may be marketed only for the approved indications and in accordance with the provisions of the approved label. If the FDA approves an application for HEPZATO, our ability to market and promote HEPZATO would be limited to the approved indication, so even with FDA approval, HEPZATO may only be promoted in this limited market. Physicians may prescribe legally available drugs for uses that are not described in the product&#8217;s labeling and that differ from those tested by us and approved by the FDA. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, impose stringent restrictions on manufacturers&#8217; communications <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">regarding&#160;off-label&#160;use,</div> and FDA approval may otherwise limit our sales practices and our ability to promote, sell and distribute the product.

Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals in the United States. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Generally, if a product with an orphan drug designation subsequently receives the first marketing approval for the indication for which it has such designation, the product is entitled to a period of marketing exclusivity, which precludes the FDA or the European Medicines Agency, or EMA, from approving another marketing application for the same indication for that drug during that time period. The applicable period is seven years in the United States and ten years in Europe. The European exclusivity period can be reduced to six years if a drug no longer meets the criteria for orphan drug designation or if the drug is sufficiently profitable so that market exclusivity is no longer justified. Orphan drug exclusivity may be lost if the FDA or the EMA determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare disease or condition. </div></div> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">28 </div></div> </div> </div> <div style="margin-top: 1em; margin-bottom: 0em; page-break-before: always;"></div> <hr style="width: 100%; height: 3px; color: rgb(153, 153, 153);"/> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We cannot assure you that any future application for orphan drug designation with respect to any product candidate will be granted. If we are unable to obtain orphan drug designation in the United States, we will not be eligible to obtain the period of market exclusivity that could result from orphan drug designation or be afforded the financial incentives associated with orphan drug designation. Even if we obtain orphan drug exclusivity for a product, that exclusivity may not effectively protect the product from competition because different drugs can be approved for the same condition. Even after an orphan drug is approved, the FDA can subsequently approve the same drug for the same condition if the FDA concludes that the later drug is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">We rely on third parties to conduct certain elements of the clinical trials for CHEMOSAT and HEPZATO, and if they do not perform their obligations to us, we may not be able to obtain regulatory approvals for our system. </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We design the clinical trials for our products, but rely on academic institutions, corporate partners, contract research organizations and other third parties to assist in managing, monitoring and otherwise carrying out these trials. We rely heavily on these parties for the execution of our clinical studies and control only certain aspects of their activities. Accordingly, we may have less control over the timing and other aspects of these clinical trials than if we conducted them entirely on our own. We rely on third parties to conduct monitoring and data collection of our ongoing and future clinical trials, including our Phase 3 ocular melanoma trial. Although we rely on these third parties to manage the data from these clinical trials, we are responsible for confirming that each of our clinical trials is conducted in accordance with our general investigational plan and protocol. Moreover, the FDA and foreign regulatory agencies require us 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. Our reliance on third parties does not relieve us of these responsibilities and requirements and if we or the third parties upon whom we rely for our clinical trials fail to comply with the applicable GCPs, the data generated in our clinical trials may be deemed unreliable and the FDA or other foreign regulatory agencies may require us to perform additional trials before approving our marketing application. We cannot assure you that, upon inspection, the FDA will determine that any of our clinical trials comply or complied with GCPs. In addition, our clinical trials must be conducted with product that complies with the FDA&#8217;s cGMP requirements. Our failure to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process, and may result in a failure to obtain regulatory approval for HEPZATO if these requirements are not met. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Purchasers of CHEMOSAT in Europe may not receive third-party reimbursement or such reimbursement may be inadequate.

In Germany, we had received a ZE diagnostic-related group code, or ZE Code, 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.

Medicare, Medicaid, private health insurance plans and their foreign equivalents will not reimburse the use of HEPZATO since the product is currently not approved for use in the United States. We will seek reimbursement by third-party payors of the cost of HEPZATO after its use is approved, but there are no assurances that adequate third-party coverage will be available to establish and maintain price levels sufficient for us to realize an appropriate return on our 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. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">Implementation of healthcare reforms in the United States and in significant overseas markets may limit the ability to commercialize CHEMOSAT and HEPZATO and the demand for CHEMOSAT and HEPZATO. 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, or the ACA, was enacted in the United States.&#160;The ACA included a number of provisions aimed at improving quality and decreasing costs. The Trump administration took executive actions and eliminated the individual shared responsibility penalty portion of the ACA. A court decision finding the ACA to be unconstitutional was appealed to the U.S. Supreme Court. On June&#160;21, 2021, the United States Supreme Court held in a <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">7-2</div> decision that the states and individuals that had previously challenged the constitutionality of the ACA&#8217;s individual mandate lacked standing to challenge the law, thus ending the legal challenges to the ACA. </div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">CHEMOSAT and HEPZATO may not achieve sufficient acceptance by the medical community to sustain our business. </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The commercial success of CHEMOSAT and HEPZATO, if approved, will depend upon their acceptance by the 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 HEPZATO or even if further testing and clinical practice produce positive results but the medical community does not view these favorably, our efforts to market CHEMOSAT and HEPZATO may fail, which would cause us to cease operation. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">We may be subject, directly or indirectly, to federal and state health care fraud and abuse laws, false claims laws and health information privacy and security laws.

We are required to maintain ISO 13485 certification for medical devices to be sold in the European Union, which requires, among other items, an implemented quality system that applies to component quality, supplier control, product design and manufacturing operations.

If we are unable to obtain an adequate supply of the necessary components or negotiate acceptable terms, we may not be able to manufacture CHEMOSAT and HEPZATO in commercial quantities or in a cost-effective manner, and commercialization of CHEMOSAT and HEPZATO in the United States, the European Union and elsewhere may be delayed. In addition, certain components are available from only a limited number of sources. Components of CHEMOSAT and HEPZATO are currently manufactured for us in small quantities.&#160;We may require significantly greater quantities to further commercialize the product. We may not be able to find alternate sources of comparable components.

If these competitors develop more effective or more affordable products or treatment methods, or achieve earlier product development, our revenues or profitability will be substantially reduced. </div></div> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">35 </div></div> </div> </div> <div style="margin-top: 1em; margin-bottom: 0em; page-break-before: always;"></div> <hr style="width: 100%; height: 3px; color: rgb(153, 153, 153);"/> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; text-indent: 0px;"></div> </div> </div> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">If another company has orphan drug designations for the same drug and indication as us and receives marketing approval before we do, then we will be blocked from marketing approval for seven years from the date of its approval for the same indication of use unless we can make a showing of the clinical superiority of our drug.</div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Risks Related to our Intellectual Property </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Intellectual property rights may not provide adequate protection, which may permit third parties to compete against us more effectively. </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Our success depends significantly on our ability to maintain and protect our proprietary rights in the technologies and inventions used in or embodied by our products. To protect our proprietary technology, we rely on patent protection, as well as a combination of copyright, trade secret and trademark laws, as well as nondisclosure, confidentiality, license and other contractual restrictions in our employment, manufacturing, consulting and other third-party agreements. These legal means may afford only limited protection, however, and may not adequately protect our rights or permit us to gain or keep any competitive advantage. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">We have not and may not be able to adequately protect our intellectual property rights throughout the world. </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Filing, prosecuting and defending patents on our products and technologies in all countries throughout the world could be prohibitively expensive. The requirements for patentability may differ in certain countries, particularly developing countries, and the breadth of patent claims allowed can be inconsistent. In addition, the laws of some foreign countries may not protect our 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 foreign countries to the extent we can in 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. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We do not have patent rights in certain foreign countries in which a market for our product and technologies exists or may exist in the future. Moreover, in 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. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-compliance</div> with these requirements. </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">The United States Patent and Trademark Office (USPTO), and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. In addition, periodic maintenance fees on issued patents often must be paid to the USPTO and foreign patent agencies over the lifetime of the patent. While an unintentional lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">Non-compliance</div> events that could result in abandonment or lapse of a patent or patent application include, but are not limited to, failure to respond to official actions within prescribed time limits, <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-payment</div> of fees and failure to properly legalize and submit formal documents.

However, patents have a limited lifespan. In the United States and the EU, the ordinary statutory natural expiration of a utility patent is generally 20 years from its filing date.

To stop any such infringement or unauthorized 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. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">In addition, third parties may initiate legal or administrative proceedings against us to challenge the validity or scope of our intellectual property rights, such as inter partes review, post-grant review, <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">re-examination</div> or opposition proceedings before the USPTO, the European Patent Office or other foreign counterparts. Third parties may also 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&#8217;s patents, we could be prevented from marketing our product in one or more foreign countries. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">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 HEPZATO 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, offer for sale, import or export our product. If our products or methods are found to infringe, we could be prevented from manufacturing or marketing our product.</div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Companies in the medical drug/device industry may use intellectual property infringement litigation to gain a competitive advantage. In the United States, patent applications filed in recent years are confidential for 18 months, while older applications are not publicly available until the patent issues. As a result, avoiding patent infringement may be difficult. Litigation may be necessary to enforce any patents issued or assigned to us or to determine the scope and validity of third-party proprietary rights. Litigation could be costly and could divert our attention from our business. There are no guarantees that we will receive a favorable outcome in any such litigation. If a third-party claims that we infringed its patents, any of the following may occur: </div></div> <div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div>

If we lose this kind of litigation, a court could require us to pay substantial damages, treble damages, and attorneys&#8217; 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 third-party 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 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. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">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. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Because of the extensive time required for development, testing and regulatory review of a potential product, it is possible that, before CHEMOSAT and HEPZATO or any other 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 European 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. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Changes in patent law could diminish the value of patents in general, thereby impairing our ability to protect our product and our technologies. </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">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. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Our trademarks may be infringed or successfully challenged, resulting in harm to our business. </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We rely on our trademarks as one means to distinguish for our customers our products from the products of our competitors, and we have registered or applied to register many of these trademarks.

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 or a likelihood of 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 infringement. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">We may rely primarily on trade secret protection for important proprietary technologies. </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">In addition to patent and trademark protection, we also rely on trade secrets, including unpatented <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">know-how,</div> technology, and other proprietary information, to maintain our competitive position. Unlike patents, trade secrets are only recognized under applicable law if they are kept secret by restricting their disclosure to third parties. We protect our trade secrets and proprietary knowledge in part through confidentiality agreements with employees, consultants and other parties. However, certain consultants and third parties with whom we have business relationships, and to whom in some cases we have disclosed trade secrets and other proprietary knowledge, may also provide services to other parties in the medical device industry, including companies, universities and research organizations that are developing competing products. In addition, some of our former employees who were exposed to certain of our trade secrets and other proprietary knowledge in the course of their employment may seek employment with, and become employed by, our competitors. We cannot be assured that consultants, employees and other third parties with whom we have entered into confidentiality agreements will not breach the terms of such agreements by improperly using or disclosing our trade secrets or other proprietary knowledge. Monitoring unauthorized uses and disclosures of our intellectual property is difficult, and we do not know whether the steps we have taken to protect our intellectual property will be effective. In addition, we may not be able to obtain adequate remedies for any such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade secrets. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Trade secret protection does not prevent independent discovery of the technology or proprietary information or use of the same. Competitors may independently duplicate or exceed our technology in whole or in part. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them, or those to whom they communicate it, from using that technology or information to compete with us in countries where we do not have patent protection. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Similar considerations apply in foreign countries where we receive approval and do not have issued patents for the current version of CHEMOSAT and HEPZATO. In these countries, our ability to successfully commercialize CHEMOSAT and HEPZATO will depend on our ability to maintain trade secret protection in these markets. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">We may be subject to damages resulting from claims that we or our employees have wrongfully used or disclosed alleged trade secrets of our competitors or are in breach of <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-competition</div> or <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-solicitation</div> agreements with our competitors. </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">We could in the future be subject to claims that we or our employees have inadvertently or otherwise used or disclosed alleged trade secrets or other proprietary information of former employers, competitors, or other third parties.

Our success also depends in part on our ability to attract and retain highly qualified scientific, technical, commercial and administrative personnel.

In addition, because CHEMOSAT and HEPZATO are intended for use in patients with cancer, there is an increased risk of death among the patients treated with our system, which may increase the risk of product liability lawsuits related to clinical trials or commercial sales. We may be subject to claims against us even if the injury is due to the actions of others. For example, if the medical personnel that use our system on patients are not properly trained or are negligent in the use of the system, the patient may be injured, which may subject us to claims. Were such a claim asserted, we would likely incur substantial legal and related expenses even if we prevail 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 our ability to market and sell the system, resulting in loss of revenue. In addition, it may be necessary for us to recall products that do not meet approved specifications, which would also result in adverse publicity and costs connected to the recall and loss of revenue. A successful products liability claim or product recall would have a material adverse effect on our business, financial condition, and results of operations. While we currently carry product liability and clinical trial insurance coverage, it may be insufficient to cover one or more large claims. </div></div> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">44 </div></div> </div> </div> <div style="margin-top: 1em; margin-bottom: 0em; page-break-before: always;"></div> <hr style="width: 100%; height: 3px; color: rgb(153, 153, 153);"/> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div id="toc663303_3" style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Item&#160;1B.

The medac Agreement provided to medac the exclusive right to market and sell CHEMOSAT in all member states of the European Union, Norway, Liechtenstein, Switzerland and the United Kingdom for which the Company was entitled to a combination of upfront and success-based milestone payments as well as a fixed transfer price per unit of CHEMOSAT and specified royalties. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">In response to medac&#8217;s subsequent dispute and <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-payment</div> of the invoice, on October&#160;12, 2021, the Company notified medac in writing that it was terminating the medac Agreement due to medac&#8217;s nonpayment of the &#8364;1&#160;million milestone payment, with the effective date of termination of the medac Agreement being April&#160;12, 2022. medac disputed having an obligation to make the milestone payment and demanded withdrawal of the termination notice. In response to medac&#8217;s continued failure to make the milestone payment and its demand for the Company to withdraw its termination notice, on December&#160;16, 2021, we initiated an arbitration proceeding pursuant to the dispute resolution procedures of the medac Agreement. Thereafter, on December&#160;30, 2021, we received a letter from medac stating that, due to our failure to withdraw the termination notice, medac was terminating the medac Agreement with immediate effect. In its letter, medac reserved its rights in full, including a purported claim for damages for wrongful termination. The arbitration proceeding is moving forward with the parties agreeing to stay the arbitration for a finite period to pursue settlement discussions. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">From time to time, claims are made against the Company in the ordinary course of business, which could result in litigation.

The FDA has granted Delcath six orphan drug designations (five for melphalan in the treatment of patients with ocular (uveal) melanoma, cutaneous melanoma, hepatocellular carcinoma, intrahepatic cholangiocarcinoma, and neuroendocrine tumors) and one for doxorubicin in the treatment of patients with hepatocellular carcinoma). HEPZATO has not been approved for sale in the United States. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Our most advanced development program is the treatment of ocular melanoma liver metastases, or mOM, a type of primary liver cancer. We are currently reviewing the incidence, unmet need, available efficacy data and development requirements for a broad set of liver cancers in order to select a portfolio of indications which will maximize the value of the HEPZATO platform. We believe that the disease states we are investigating and intend to investigate are unmet medical needs that represent significant market opportunities. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We are investigating the objective response rate of HEPZATO in patients with mOM in our FOCUS Clinical Trial for Patients with Hepatic Dominant Ocular Melanoma, or the FOCUS Trial, a global registration clinical trial. For information on the FOCUS Trial, see &#8220;Part I, Item 1. Business&#8212;Clinical Development Program&#8212;The FOCUS Trial&#8221; above. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;">Due to the global outbreak of <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">SARS-CoV-2,</div></div> a novel strain of coronavirus that causes Coronavirus disease <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">(COVID-19),</div> the Company experienced an impact on certain areas of its business. These effects included a slowing of patient recruitment in the FOCUS Trial and a reduction in the pace at which we can monitor data at our clinical trial sites. The resulting delay in completing enrollment and additional time required to monitor data caused our planned announcement for the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">top-line</div> data from our FOCUS Trial to shift to December 2021. In December 2021, we announced that HEPZATO met its prespecified endpoint. Based on the FOCUS Trial results, we are preparing to submit a new drug application, or NDA, to the FDA for HEPZATO. We plan to request a <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">pre-NDA</div> meeting with the FDA and, pending feedback from FDA and the pace of complete data analysis from our clinical sites which have been impacted by the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19</div> pandemic, we intend to submit an NDA to the FDA by <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">mid-2022</div> for the use of HEPZATO in the treatment of mOM. The results of the FOCUS Trial should also support securing reimbursement coverage for the use of CHEMOSAT in the European Union. Additional impacts of <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">COVID-19</div> on our business may arise that we are not aware of currently.

The core principle of ASC 606 requires that an entity 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. ASC 606 defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The following five steps are applied to achieve that core principle: </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Step 1: Identify the contract with the customer; </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Step 2: Identify the performance obligations in the contract; </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Step 3: Determine the transaction price, including an estimation of any variable consideration expected to be received in connection with the contract; </div></div> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">50 </div></div> </div> </div> <div style="margin-top: 1em; margin-bottom: 0em; page-break-before: always;"></div> <hr style="width: 100%; height: 3px; color: rgb(153, 153, 153);"/> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"></div> </div> </div> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Step 4: Allocate the transaction price to the performance obligations in the contract; and </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Step 5: Recognize revenue when the company satisfies a performance obligation. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Each of these steps in the revenue recognition process requires management to make judgments 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. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 12pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">As required by GAAP, the Company disaggregates its revenue into the categories of product revenue and other revenue. The Company recognizes product revenue and milestone payments at a point in time, whereas other revenues (primarily license fees) are recognized over time. 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 </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Accrued Expenses </div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">We utilize contract research organizations in order to perform research and development and conduct clinical trials. In some cases, these organization do not bill on a timely basis. Management monitors certain key drivers of these costs and estimates accruals in an attempt to properly match expenses incurred with the appropriate reporting period. However, there is judgment involved and the actual billings could be more or less than the estimated accrual. </div></div> <div id="toc663303_9" style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Item&#160;7A.

In Europe, Delcath&#8217;s commercial product is a stand-alone medical device having the same device components as the HEPZATO KIT, but without the melphalan hydrochloride, and is approved for sale under the trade name CHEMOSAT<div style="font-size: 85%; vertical-align: top;;display:inline;;font-size:9.4px">&#174;</div> Hepatic Delivery System for Melphalan, or CHEMOSAT, where it has been used at major medical centers to treat a wide range of cancers of the liver. </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"> </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="text-indent: 0px; letter-spacing: 0px; top: 0px;;display:inline;">Delcath&#8217;s clinical development program (&#8220;CDP&#8221;) for HEPZATO is comprised of the FOCUS Clinical Trial for Patients with Hepatic Dominant Ocular Melanoma (the &#8220;FOCUS Trial&#8221;), a global registration clinical trial that is investigating objective response rate in metastatic ocular melanoma, or mOM. The Company is currently reviewing the incidence, unmet need, available efficacy data and development requirements for a broad set of liver cancers in order to select a portfolio of <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">follow-on</div> indications which will maximize the value of the HEPZATO platform.</div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">In the United States, HEPZATO is considered a combination drug and device product regulated by the Food and Drug Administration (&#8220;FDA&#8221;). Primary jurisdiction for regulation of HEPZATO has been assigned to the FDA&#8217;s Center for Drug Evaluation and Research. The FDA has granted Delcath six orphan drug designations (five for melphalan in ocular melanoma, cutaneous melanoma, cholangiocarcinoma, hepatocellular carcinoma, and neuroendocrine tumor indications and one for doxorubicin in the hepatocellular carcinoma indication). HEPZATO has not been approved for sale in the United States. </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Risks and Uncertainties </div></div></div></div></div> <div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;"> </div></div></div> <ix:nonNumeric name="dcth:RiskAndUncertaintiesPolicyTextBlock" contextRef="P01_01_2021To12_31_2021" escape="true"><div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="letter-spacing: 0px; top: 0px;;display:inline;">Due to the global outbreak of <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">SARS-CoV-2,</div></div> a novel strain of coronavirus that causes Coronavirus disease <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">(COVID-19),</div> the Company experienced an impact on certain areas of its business. These effects included a slowing of patient recruitment in the FOCUS trial and a reduction in the pace at which the Company can monitor data at its clinical trial sites. The resulting delay in completing enrollment and additional time required to monitor data has caused the Company&#8217;s planned announcement for the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">top-line</div> data from its FOCUS Trial to shift to early 2021 and to be modified to a preliminary analysis. The Company now plans to submit a New Drug Application (NDA) to the FDA mid-2022 for the treatment of mOM. The ability to achieve this goal is contingent on the Company&#8217;s ability to monitor data at its clinical sites and therefore the timeline may shift as access to the clinical sites changes in response to the rapidly evolving situation. The Company also has experienced a decline in EU commercial product revenue and additional impacts to the business may arise that the Company is not aware of currently. The ultimate impact of the pandemic on the Company&#8217;s results of operations, financial position, liquidity, or capital resources cannot be reasonably estimated at this time. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px; text-indent: 0px;;display:inline;">Although Delcath is not aware of any direct impacts of the war between the Ukraine and the Russian Federation on its supply chain, the war could adversely impact Delcath&#8217;s ability to obtain components and/or significantly increase the cost of obtaining such components for the Company&#8217;s products from its third-party suppliers in a timely manner or at all.</div></div></div> <div style="letter-spacing: 0px; top: 0px;;display:inline;"> </div></ix:nonNumeric> <ix:nonNumeric name="dcth:LiquidityAndGoingConcernPolicyTextBlock" contextRef="P01_01_2021To12_31_2021" escape="true" continuedAt="TextSelection_42052533"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Liquidity and Going Concern </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The accompanying 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.

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. </div></div> </ix:continuation></ix:continuation> <ix:nonNumeric name="us-gaap:BasisOfAccounting" contextRef="P01_01_2021To12_31_2021" escape="true"><div style="font-size: 18pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 18pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div>

Revenue is recognized when or as the Company transfers control of the promised goods or services to its customers in an amount that reflects the consideration to which the Company expects 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. </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Delcath may enter into contracts with partners that contain multiple elements such as licensing, development, manufacturing, and commercialization components.

The core principle of ASC 606 requires that an entity 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. ASC 606 defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. </div></div></div> <div style="font-family: &quot;Times New Roman&quot;;

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 management believes 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. Management believes this provides a reasonable basis for recognizing revenue; however, actual results could differ from estimates and significant changes in estimates could impact the Company&#8217;s results of operations in future periods. </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">As required by ASC 606, the Company disaggregates its revenue into the categories of product revenue and other revenue. The Company recognizes product revenue and milestone payments at a point in time, whereas other revenues (primarily license fees) are recognized over time. 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.

A receivable is recorded when revenue is recognized prior to payment and the Company has an unconditional right to payment. Alternatively, when payment precedes the provision of the related services, the Company records deferred revenue until the performance obligations are satisfied.

Under 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&#8217; requisite service period (generally the vesting period of the equity grant). The Company expenses its share-based compensation granted under the accelerated method, which treats each vesting tranche as if it were an individual grant. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;">The Company periodically grants stock options for a fixed number of shares of common stock to its employees, directors, and <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-employee</div> contractors, with an exercise price greater than or equal to the fair market value of the common stock at the date of the grant. The Company estimates the fair value of stock options using an option pricing model. Key inputs used to estimate the fair value of stock options include the exercise price of the option, the expected term, the expected volatility of the stock over the option&#8217;s expected term, the risk-free interest rate over the option&#8217;s expected term, and the expected annual dividend yield. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by persons who receive equity awards. </div></div></ix:nonNumeric> <ix:nonNumeric name="us-gaap:IncomeTaxPolicyTextBlock" contextRef="P01_01_2021To12_31_2021" escape="true"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Income Taxes </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The Company accounts for income taxes following the asset and liability method in accordance with the ASC 740 &#8220;Income Taxes.&#8221; 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.

In a letter dated, June&#160;29, 2020, an attorney representing the Claimants made certain claims and threatened litigation against the Company. On or about July&#160;27, 2020, the Claimants filed a statement of claim with the American Arbitration Association against the Company. The Claimants sought payment of certain purported unpaid compensation amounts claimed to be due to them, in an approximate amount of $<ix:nonFraction name="us-gaap:LossContingencyDamagesSoughtValue" contextRef="P07_27_2020To07_27_2020_PendingLitigationMemberusgaapLitigationStatusAxis" unitRef="Unit_USD" decimals="-3" scale="3" format="ixt:numdotdecimal">1,140</ix:nonFraction> in the aggregate, as well as unspecified statutory damages under New York Labor Law, attorneys&#8217; fees and costs, and statutory interest.

Pursuant to the License Agreement, a milestone is due upon achieving positive efficacy in the FOCUS trial as defined by the FOCUS trial protocol. Per the trial protocol and associated Statistical Analysis Plan, positive efficacy is based on whether the Objective Response Rate (ORR) exceeds a prespecified threshold. A preliminary analysis of the FOCUS trial data based on <ix:nonFraction name="dcth:PercentageOfEnrolledPatients" contextRef="P03_30_2021To03_31_2021" unitRef="Unit_pure" decimals="2" scale="-2" format="ixt:numdotdecimal">87</ix:nonFraction>% of enrolled patients was released on March&#160;31, 2021, and subsequently presented at the American Society of Clinical Oncology (ASCO) Annual Meeting held virtually from the 4th through the 8th of June 2021. Per that analysis, the ORR exceeded the prespecified threshold. While the final ORR is not yet known, given the magnitude by which the ORR exceeded the prespecified endpoint and the small number of patients yet to be assessed, the final ORR will be greater than the prespecified endpoint regardless of the responder status of the remaining patients. medac disagrees that the milestone is due and claims that a full clinical study report is required in addition to the existing ORR analysis. medac has not disputed the accuracy of the ORR analysis or underlying data, but simply asserts that a full clinical study report is required prior to payment. </div><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">While the Company disagrees with this interpretation, since medac has stated they do not intend to pay the invoice at this time, under revenue recognition criteria set out in ASC 606, the Company cannot recognize the revenue in the year ending December&#160;31, 2021. </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">On October&#160;12, 2021, the Company notified medac in writing that it was terminating the License Agreement </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"> </div></ix:nonNumeric> <div style="font-size: 8pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 8pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"></div></div> <div style="text-align: center; font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; text-indent: 0px;"><div style="display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">F-27 </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"></div> </div> </div> </div> <div style="margin-top: 1em; margin-bottom: 0em; page-break-before: always;"></div> <hr style="width: 100%; height: 3px; color: rgb(153, 153, 153);"/> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="text-align: center; font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; text-indent: 0px;"></div> </div> </div> </div> <div> <div style="text-align: center;"> <div style="width: 8.5in; text-align: left; margin-right: auto; margin-left: auto;"> <div style="text-align: center; font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">DELCATH SYSTEMS, INC. </div></div></div> <div style="text-align: center; font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Notes to Consolidated Financial Statements </div></div></div> <div style="text-align: center; font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-weight:bold;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">for the Years Ended December 31, 2021 and 2020 </div></div></div> <div style="text-align: center; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">(amounts in thousands, except share and per share amounts)</div></div><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;"> </div></div></div> <div style="font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 12pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div>

HEPZATO is designed to administer high-dose chemotherapy to the liver while controlling systemic exposure and associated side effects. In Europe, Delcath&#8217;s commercial product is a stand-alone medical device having the same device components as the HEPZATO KIT, but without the melphalan hydrochloride, and is approved for sale under the trade name CHEMOSAT<div style="font-size: 85%; vertical-align: top;;display:inline;;font-size:9.4px">&#174;</div> Hepatic Delivery System for Melphalan, or CHEMOSAT, where it has been used at major medical centers to treat a wide range of cancers of the liver. </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"> </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="text-indent: 0px; letter-spacing: 0px; top: 0px;;display:inline;">Delcath&#8217;s clinical development program (&#8220;CDP&#8221;) for HEPZATO is comprised of the FOCUS Clinical Trial for Patients with Hepatic Dominant Ocular Melanoma (the &#8220;FOCUS Trial&#8221;), a global registration clinical trial that is investigating objective response rate in metastatic ocular melanoma, or mOM. The Company is currently reviewing the incidence, unmet need, available efficacy data and development requirements for a broad set of liver cancers in order to select a portfolio of <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">follow-on</div> indications which will maximize the value of the HEPZATO platform.</div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">In the United States, HEPZATO is considered a combination drug and device product regulated by the Food and Drug Administration (&#8220;FDA&#8221;). Primary jurisdiction for regulation of HEPZATO has been assigned to the FDA&#8217;s Center for Drug Evaluation and Research. The FDA has granted Delcath six orphan drug designations (five for melphalan in ocular melanoma, cutaneous melanoma, cholangiocarcinoma, hepatocellular carcinoma, and neuroendocrine tumor indications and one for doxorubicin in the hepatocellular carcinoma indication). HEPZATO has not been approved for sale in the United States. </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Risks and Uncertainties </div></div></div></div></div> <div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;"> </div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="letter-spacing: 0px; top: 0px;;display:inline;">Due to the global outbreak of <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"><div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">SARS-CoV-2,</div></div> a novel strain of coronavirus that causes Coronavirus disease <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">(COVID-19),</div> the Company experienced an impact on certain areas of its business. These effects included a slowing of patient recruitment in the FOCUS trial and a reduction in the pace at which the Company can monitor data at its clinical trial sites. The resulting delay in completing enrollment and additional time required to monitor data has caused the Company&#8217;s planned announcement for the <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">top-line</div> data from its FOCUS Trial to shift to early 2021 and to be modified to a preliminary analysis. The Company now plans to submit a New Drug Application (NDA) to the FDA mid-2022 for the treatment of mOM. The ability to achieve this goal is contingent on the Company&#8217;s ability to monitor data at its clinical sites and therefore the timeline may shift as access to the clinical sites changes in response to the rapidly evolving situation. The Company also has experienced a decline in EU commercial product revenue and additional impacts to the business may arise that the Company is not aware of currently. The ultimate impact of the pandemic on the Company&#8217;s results of operations, financial position, liquidity, or capital resources cannot be reasonably estimated at this time. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px; text-indent: 0px;;display:inline;">Although Delcath is not aware of any direct impacts of the war between the Ukraine and the Russian Federation on its supply chain, the war could adversely impact Delcath&#8217;s ability to obtain components and/or significantly increase the cost of obtaining such components for the Company&#8217;s products from its third-party suppliers in a timely manner or at all.</div></div></div> <div style="letter-spacing: 0px; top: 0px;;display:inline;"> </div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Liquidity and Going Concern </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The accompanying 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.

Adequate additional financing may not be available to the Company 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 its research and development programs or any commercialization efforts. There can be no assurance that the Company&#8217;s efforts will result in the resolution of the Company&#8217;s liquidity needs. 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. The accompanying consolidated financial statements do not include any adjustments that might result should the Company be unable to continue as a going concern. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The Company anticipates incurring additional losses until such time, if ever, that it can generate significant sales. These circumstances raise substantial doubt about the Company&#8217;s ability&#160;to continue as a going concern within one year after the date that the financial statements are issued. 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. </div></div> <span></span>

The amounts of assets and liabilities reported in the Company&#8217;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 valuation of warrants, 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. </div></div> <div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Cash Equivalents and Concentrations of Credit Risk </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The Company considers investments with original maturities of three months or less at date of acquisition to be cash equivalents.

Maintenance and repairs are charged to operations as incurred. Expenditures which substantially increase the useful lives of the related assets are capitalized. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Fair Value Measurements </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The Company adheres to Accounting Standards Codification (&#8220;ASC&#8221;) 820, Fair Value Measurement, which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements.

Revenue is recognized when or as the Company transfers control of the promised goods or services to its customers in an amount that reflects the consideration to which the Company expects 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. </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">Delcath may enter into contracts with partners that contain multiple elements such as licensing, development, manufacturing, and commercialization components.

The core principle of ASC 606 requires that an entity 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. ASC 606 defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"> </div> <div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The following five steps are applied to achieve that core principle: </div></div> <div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div>

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 management believes 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. Management believes this provides a reasonable basis for recognizing revenue; however, actual results could differ from estimates and significant changes in estimates could impact the Company&#8217;s results of operations in future periods. </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"/> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">As required by ASC 606, the Company disaggregates its revenue into the categories of product revenue and other revenue. The Company recognizes product revenue and milestone payments at a point in time, whereas other revenues (primarily license fees) are recognized over time. 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. See Note 13 &#8211; Commitments and Contingencies &#8211; Litigations, Claims and Assessments &#8211; medac Matter. </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"> </div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Deferred Revenue </div></div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"/> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The timing of the Company&#8217;s revenue recognition may differ from the timing of payment by its customers. A receivable is recorded when revenue is recognized prior to payment and the Company has an unconditional right to payment. Alternatively, when payment precedes the provision of the related services, the Company records deferred revenue until the performance obligations are satisfied.

Under 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&#8217; requisite service period (generally the vesting period of the equity grant). The Company expenses its share-based compensation granted under the accelerated method, which treats each vesting tranche as if it were an individual grant. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;">The Company periodically grants stock options for a fixed number of shares of common stock to its employees, directors, and <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-employee</div> contractors, with an exercise price greater than or equal to the fair market value of the common stock at the date of the grant. The Company estimates the fair value of stock options using an option pricing model. Key inputs used to estimate the fair value of stock options include the exercise price of the option, the expected term, the expected volatility of the stock over the option&#8217;s expected term, the risk-free interest rate over the option&#8217;s expected term, and the expected annual dividend yield. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by persons who receive equity awards. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Income Taxes </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The Company accounts for income taxes following the asset and liability method in accordance with the ASC 740 &#8220;Income Taxes.&#8221; 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. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-weight:bold;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;">Net Loss per Common Share </div></div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">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 </div></div> <div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"><div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;">&#160;</div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">shares that are issuable for little or no cash consideration.

In a letter dated, June&#160;29, 2020, an attorney representing the Claimants made certain claims and threatened litigation against the Company. On or about July&#160;27, 2020, the Claimants filed a statement of claim with the American Arbitration Association against the Company. The Claimants sought payment of certain purported unpaid compensation amounts claimed to be due to them, in an approximate amount of $1,140 in the aggregate, as well as unspecified statutory damages under New York Labor Law, attorneys&#8217; fees and costs, and statutory interest. The Claimants and the Company agreed to participate in <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">non-binding</div> mediation of their dispute before a neutral mediator, which resulted in the arbitration proceedings being placed in abeyance pending the outcome of the mediation process. With the assistance of the neutral mediator and after careful consideration by the Company&#8217;s board of directors following several weeks of negotiations, the Claimants and the Company agreed in <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">mid-May</div> of 2021 to a confidential settlement of their dispute to avoid the expenses and distractions of further arbitration proceedings, with no admission of liability or wrongdoing on the part of the Company. While the Company had accrued for the full purported unpaid compensation amount of $1,140 as of December&#160;31, 2020, the Company ultimately paid less in full and final settlement of its dispute with both of the Claimants. As a result of the confidential settlement, the AAA Arbitration was dismissed with prejudice on June&#160;1, 2021. </div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="text-indent: 0px;;font-style:italic;display:inline;">medac Matter</div></div></div></div> <div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-style:italic;display:inline;"> </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">In April 2021, the Company issued an invoice for &#8364;1,000 (which currently converts to approximately $1,160) to medac GmbH, a privately held, multi-national pharmaceutical company based in Germany (&#8220;medac&#8221;), the Company&#8217;s EU product distribution partner, for a milestone payment due under the License, Supply and Marketing Agreement (the &#8220;License Agreement&#8221;) dated December 10, 2018, between the Company and medac. Pursuant to the License Agreement, a milestone is due upon achieving positive efficacy in the FOCUS trial as defined by the FOCUS trial protocol. Per the trial protocol and associated Statistical Analysis Plan, positive efficacy is based on whether the Objective Response Rate (ORR) exceeds a prespecified threshold. A preliminary analysis of the FOCUS trial data based on 87% of enrolled patients was released on March&#160;31, 2021, and subsequently presented at the American Society of Clinical Oncology (ASCO) Annual Meeting held virtually from the 4th through the 8th of June 2021. Per that analysis, the ORR exceeded the prespecified threshold. While the final ORR is not yet known, given the magnitude by which the ORR exceeded the prespecified endpoint and the small number of patients yet to be assessed, the final ORR will be greater than the prespecified endpoint regardless of the responder status of the remaining patients. medac disagrees that the milestone is due and claims that a full clinical study report is required in addition to the existing ORR analysis. medac has not disputed the accuracy of the ORR analysis or underlying data, but simply asserts that a full clinical study report is required prior to payment. </div><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">While the Company disagrees with this interpretation, since medac has stated they do not intend to pay the invoice at this time, under revenue recognition criteria set out in ASC 606, the Company cannot recognize the revenue in the year ending December&#160;31, 2021. </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"/> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">On October&#160;12, 2021, the Company notified medac in writing that it was terminating the License Agreement </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"> </div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">due to medac&#8217;s nonpayment of the milestone payment due under the License Agreement, with the effective date of termination of the License Agreement being April&#160;12, 2022. medac disputed having an obligation to make a milestone payment under the Agreement and demanded withdrawal of the termination notice. The Company declined to withdraw the termination notice and, on December&#160;16, 2021, the Company initiated an arbitration proceeding pursuant to the dispute resolution provisions of the Agreement. The arbitration proceeding is moving forward with the parties agreeing to stay the arbitration for a finite period to pursue settlement discussions. </div></div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px; text-indent: 0px;;display:inline;"><div style="letter-spacing: 0px; top: 0px;;display:inline;">On December 30, 2021, the Company received a letter from medac stating that, due to its failure to withdraw the termination notice, medac was terminating the License Agreement with immediate effect. In the letter, medac reserved its rights in full, including a purported claim for damages for wrongful termination. In a separate letter, medac agreed to orderly transition through February 28, 2022 in order to minimize the impact of any termination on patients and physicians.

A significant portion of the federal amount is subject to an annual limitation as low as $28 as a result of changes in the Company&#8217;s ownership in May 2003, November 2016, and multiple dates throughout 2017, 2018, 2019 and 2021, as defined by Section&#160;382 of the United States Internal Revenue Code of 1986, as amended (the &#8220;IRC&#8221;), and </div></div>  <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">the related income tax regulations. As a result of the limitations caused by the multiple ownership changes, approximately $204,458 of the total net operating loss carryforwards is expected to expire unutilized and will be unavailable to offset future federal taxable income. Approximately $72,940 of net operating loss carryforwards remains available to offset future federal taxable income, of which $1,737 will expire between 2022 and 2037 and $71,203 will have an unlimited carryforward period as a result of the Tax Cuts and Jobs Act. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">In addition, the Company&#8217;s state net operating losses are also subject to annual limitations that generally follow the IRC Section&#160;382 provisions (with the exception of Connecticut), adjusted for each state&#8217;s respective income apportionment percentages. As of December&#160;31, 2021, and 2020, the Company had net operating loss carryforwards for state and city income tax purposes between approximately $24,760 and $193,680 and between approximately $26,414 and $192,466, respectively, which expire through 2041. As a result of the Section&#160;382 limitations, approximately $191,914 and $176,137 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 $1,766 and $1,737 of net operating loss carryforwards, respectively, will be available to offset future state and city taxable income. As of December&#160;31, 2021 and 2020 the Company had a net operating loss carryforward for foreign income tax purposes of $27,951 and $30,880, respectively, which have indefinite carryforward periods. As of December&#160;31, 2021 and 2020, the Company had federal research and development tax credit carryforwards of approximately $5,833 and $5,458, respectively, which expire through 2041.

The CARES Act includes a variety of economic and tax relief measures intended to stimulate the economy, including loans for small businesses, payroll tax credits/deferrals, and corporate income tax relief. Due the Company&#8217;s history of tax loss carryforwards and full valuation allowance, the CARES Act did not have a significant effect to the income tax provision, as the corporate income tax relief was directed towards cash taxpayers. </div></div> <div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;">The Company complies with the provisions of ASC <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">740-10</div> in accounting for its uncertain tax positions. ASC <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">740-10</div> 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 <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">740-10,</div> 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 <div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;">740-10</div> and therefore has not included a tabular roll forward of unrecognized tax benefits. As there are no uncertain tax positions recognized, interest and penalties have not been accrued. </div>  <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">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&#8217;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&#160;31, 2018; tax years ending December 31, 2018 through December 31, 2021 remain open to examination. The Republic of Ireland is the Company&#8217;s only significant foreign jurisdiction. The Company is no longer subject to Ireland tax examination for tax years ending prior to December&#160;31, 2017 (as Ireland has not initiated an audit of 2016 as of December&#160;31, 2021); tax years ending December&#160;31, 2017 through December&#160;31, 2021 remain open to examination. However, the Company&#8217;s tax years December 31, 1998 through December 31, 2021 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. </div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"/> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"><div style="letter-spacing: 0px; top: 0px;;display:inline;"><div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The Company recognizes interest accrued related to unrecognized tax benefits and penalties, if incurred, as a component of income tax expense. </div></div></div> <div style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"> </div><span></span>

These effects included a slowing of patient recruitment in the FOCUS trial and a reduction in the pace at which the Company can monitor data at its clinical trial sites.

Variable consideration is recognized at an amount management believes 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.

The Company estimates the fair value of stock options using an option pricing model. Key inputs used to estimate the fair value of stock options include the exercise price of the option, the expected term, the expected volatility of the stock over the option&#8217;s expected term, the risk-free interest rate over the option&#8217;s expected term, and the expected annual dividend yield. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by persons who receive equity awards. </div></div><span></span>

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. </div></div><span></span>

This standard is effective for fiscal years beginning after December&#160;15, 2021, including interim periods within those fiscal years. Issuers should apply the new standard prospectively to modifications or exchanges occurring after the effective date of the new standard.

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>

(&#x201c;Delcath&#x201d; or the &#x201c;Company&#x201d;) is an interventional oncology company focused on the treatment of primary and metastatic liver cancers. The Company&#x2019;s lead product candidate, the HEPZATO&lt;div style="font-size: 85%; vertical-align: top;;display:inline;;font-size:9.4px"&gt;&#x2122;&lt;/div&gt; KIT (melphalan hydrochloride for injection/hepatic delivery system), or HEPZATO&lt;div style="font-size: 85%; vertical-align: top;;display:inline;;font-size:9.4px"&gt;&#x2122;&lt;/div&gt;, is a drug/device combination product. HEPZATO is designed to administer high-dose chemotherapy to the liver while controlling systemic exposure and associated side effects. In Europe, Delcath&#x2019;s commercial product is a stand-alone medical device having the same device components as the HEPZATO KIT, but without the melphalan hydrochloride, and is approved for sale under the trade name CHEMOSAT&lt;div style="font-size: 85%; vertical-align: top;;display:inline;;font-size:9.4px"&gt;&#xae;&lt;/div&gt; Hepatic Delivery System for Melphalan, or CHEMOSAT, where it has been used at major medical centers to treat a wide range of cancers of the liver. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt; &lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="text-indent: 0px; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Delcath&#x2019;s clinical development program (&#x201c;CDP&#x201d;) for HEPZATO 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 metastatic ocular melanoma, or mOM. The Company is currently reviewing the incidence, unmet need, available efficacy data and development requirements for a broad set of liver cancers in order to select a portfolio of &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;follow-on&lt;/div&gt; indications which will maximize the value of the HEPZATO platform.&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;In the United States, HEPZATO is considered a combination drug and device product regulated by the Food and Drug Administration (&#x201c;FDA&#x201d;). Primary jurisdiction for regulation of HEPZATO has been assigned to the FDA&#x2019;s Center for Drug Evaluation and Research. The FDA has granted Delcath six orphan drug designations (five for melphalan in ocular melanoma, cutaneous melanoma, cholangiocarcinoma, hepatocellular carcinoma, and neuroendocrine tumor indications and one for doxorubicin in the hepatocellular carcinoma indication). HEPZATO has not been approved for sale in the United States. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;"&gt;Risks and Uncertainties &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;"&gt; &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Due to the global outbreak of &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;SARS-CoV-2,&lt;/div&gt;&lt;/div&gt; a novel strain of coronavirus that causes Coronavirus disease &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;(COVID-19),&lt;/div&gt; the Company experienced an impact on certain areas of its business. These effects included a slowing of patient recruitment in the FOCUS trial and a reduction in the pace at which the Company can monitor data at its clinical trial sites.

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;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;"&gt;Fair Value Measurements &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Company adheres to Accounting Standards Codification (&#x201c;ASC&#x201d;) 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;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;ASC 820 emphasizes that fair value is a market-based measurement, not an entity-specific measurement.&#160;Therefore, a fair value measurement should be determined based on the assumptions that &lt;/div&gt;&lt;/div&gt; &lt;div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;market participants would use in pricing the asset or liability.&#160;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&#160;3 of the hierarchy). &lt;/div&gt;&lt;/div&gt; &lt;div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;/div&gt;

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 liability. &lt;/div&gt;&lt;/div&gt;  &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;"&gt;Revenue Recognition &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"/&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Revenue is generated from proprietary and partnered product sales and license and royalty arrangements. Revenue is recognized when or as the Company transfers control of the promised goods or services to its customers in an amount that reflects the consideration to which the Company expects 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;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Delcath may enter into contracts with partners that contain multiple elements such as licensing, development, manufacturing, and commercialization components. These arrangements are often complex, and the Company may receive various types of consideration over the life of the arrangement, including up-front fees, reimbursements for research and development services, milestone payments, payments on product shipments, margin sharing arrangements, license fees and royalties. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers (&#x201c;ASC 606&#x201d;). The core principle of ASC 606 requires that an entity 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. ASC 606 defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt; &lt;/div&gt; &lt;div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;/div&gt; &lt;div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The following five steps are applied to achieve that core principle: &lt;/div&gt;&lt;/div&gt; &lt;div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;/div&gt;

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 management believes 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. Management believes this provides a reasonable basis for recognizing revenue; however, actual results could differ from estimates and significant changes in estimates could impact the Company&#x2019;s results of operations in future periods. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"/&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;As required by ASC 606, the Company disaggregates its revenue into the categories of product revenue and other revenue. The Company recognizes product revenue and milestone payments at a point in time, whereas other revenues (primarily license fees) are recognized over time. 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. See Note 13 &#x2013; Commitments and Contingencies &#x2013; Litigations, Claims and Assessments &#x2013; medac Matter. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt; &lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;"&gt;Deferred Revenue &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"/&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The timing of the Company&#x2019;s revenue recognition may differ from the timing of payment by its customers. A receivable is recorded when revenue is recognized prior to payment and the Company has an unconditional right to payment.

Under 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&#x2019; requisite service period (generally the vesting period of the equity grant). The Company expenses its share-based compensation granted under the accelerated method, which treats each vesting tranche as if it were an individual grant. &lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Company periodically grants stock options for a fixed number of shares of common stock to its employees, directors, and &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-employee&lt;/div&gt; contractors, with an exercise price greater than or equal to the fair market value of the common stock at the date of the grant. The Company estimates the fair value of stock options using an option pricing model. Key inputs used to estimate the fair value of stock options include the exercise price of the option, the expected term, the expected volatility of the stock over the option&#x2019;s expected term, the risk-free interest rate over the option&#x2019;s expected term, and the expected annual dividend yield. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by persons who receive equity awards. &lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;"&gt;Income Taxes &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Company accounts for income taxes following the asset and liability method in accordance with the ASC 740 &#x201c;Income Taxes.&#x201d; 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;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;"&gt;Net Loss per Common Share &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&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 &lt;/div&gt;&lt;/div&gt; &lt;div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;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. &lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;For the years ended December&#160;31, 2021 and 2020 the following potentially dilutive securities were excluded from the computation of diluted earnings per share because their effects would be antidilutive: &lt;/div&gt;&lt;/div&gt; &lt;div style="font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-size: 12pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;/div&gt;

ASU &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;2020-06&lt;/div&gt; requires entities to provide expanded disclosures about the terms and features of convertible instruments and amends certain guidance in ASC 260,&#160;Earnings per Share, relating to the computation of earnings per share for convertible instruments and contracts in an entity&#x2019;s own equity. The guidance becomes effective for the Company on January&#160;1, 2024, with early adoption permitted. The Company early adopted ASU &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;2020-06&lt;/div&gt; on January&#160;1, 2022 and the adoption is not expected to have any immediate effect on the Company&#x2019;s financial statements.

The guidance is effective for the Company beginning in the first quarter of fiscal year 2022 with early adoption permitted.

This standard is effective for fiscal years beginning after December&#160;15, 2021, including interim periods within those fiscal years. Issuers should apply the new standard prospectively to modifications or exchanges occurring after the effective date of the new standard. Early adoption is permitted, including adoption in an interim period. If an issuer elects to early adopt the new standard in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes that interim period.

Revenue is recognized when or as the Company transfers control of the promised goods or services to its customers in an amount that reflects the consideration to which the Company expects 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;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Delcath may enter into contracts with partners that contain multiple elements such as licensing, development, manufacturing, and commercialization components. These arrangements are often complex, and the Company may receive various types of consideration over the life of the arrangement, including up-front fees, reimbursements for research and development services, milestone payments, payments on product shipments, margin sharing arrangements, license fees and royalties. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers (&#x201c;ASC 606&#x201d;). The core principle of ASC 606 requires that an entity 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. ASC 606 defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt; &lt;/div&gt; &lt;div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;/div&gt; &lt;div style="text-indent: 4%; font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The following five steps are applied to achieve that core principle: &lt;/div&gt;&lt;/div&gt; &lt;div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;/div&gt;

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 management believes 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. Management believes this provides a reasonable basis for recognizing revenue; however, actual results could differ from estimates and significant changes in estimates could impact the Company&#x2019;s results of operations in future periods. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"/&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;As required by ASC 606, the Company disaggregates its revenue into the categories of product revenue and other revenue. The Company recognizes product revenue and milestone payments at a point in time, whereas other revenues (primarily license fees) are recognized over time. 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.

Under 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&#x2019; requisite service period (generally the vesting period of the equity grant). The Company expenses its share-based compensation granted under the accelerated method, which treats each vesting tranche as if it were an individual grant. &lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Company periodically grants stock options for a fixed number of shares of common stock to its employees, directors, and &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-employee&lt;/div&gt; contractors, with an exercise price greater than or equal to the fair market value of the common stock at the date of the grant. The Company estimates the fair value of stock options using an option pricing model. Key inputs used to estimate the fair value of stock options include the exercise price of the option, the expected term, the expected volatility of the stock over the option&#x2019;s expected term, the risk-free interest rate over the option&#x2019;s expected term, and the expected annual dividend yield. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by persons who receive equity awards. &lt;/div&gt;&lt;/div&gt;</us-gaap:ShareBasedCompensationOptionAndIncentivePlansPolicy>

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.

ASU &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;2020-06&lt;/div&gt; requires entities to provide expanded disclosures about the terms and features of convertible instruments and amends certain guidance in ASC 260,&#160;Earnings per Share, relating to the computation of earnings per share for convertible instruments and contracts in an entity&#x2019;s own equity. The guidance becomes effective for the Company on January&#160;1, 2024, with early adoption permitted. The Company early adopted ASU &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;2020-06&lt;/div&gt; on January&#160;1, 2022 and the adoption is not expected to have any immediate effect on the Company&#x2019;s financial statements.

This standard is effective for fiscal years beginning after December&#160;15, 2021, including interim periods within those fiscal years. Issuers should apply the new standard prospectively to modifications or exchanges occurring after the effective date of the new standard. Early adoption is permitted, including adoption in an interim period. If an issuer elects to early adopt the new standard in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes that interim period. The Company adopted this guidance on January&#160;1, 2022 and it did not have a material impact on its consolidated financial statements.&lt;/div&gt;&lt;/div&gt; </us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

(the &#x201c;Lender,&#x201d; or &#x201c;Avenue&#x201d;) for a term loan in an aggregate principal amount of up to $20,000 (the &#x201c;Avenue Loan&#x201d;). The Avenue Loan bears interest at an annual rate equal to the greater of (a) the sum of 7.70% plus the prime rate as reported in The Wall Street Journal and (b) 10.95%. The interest rate at December 31, 2021 was 10.95%. The Avenue Loan is secured by all of the Company&#x2019;s assets globally, including intellectual property. The Avenue Loan matures on August 1, 2024. &lt;/div&gt;&lt;/div&gt; &lt;div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The initial tranche of the Avenue Loan is $15,000, including $4,000 which has been funded into a restricted account and will be released upon achievement of (a)(x) positive FOCUS trial efficacy per the trial&#x2019;s predefined Statistical Analysis Plan (SAP) (specifically the Overall Response Rate exceeds the prespecified threshold for success defined in the SAP by a statistically significant amount); and (y)&#160;based on data contained within the FOCUS trial database and appropriate for use with the U.S. Food and Drug Administration, safety and tolerability among FOCUS trial participants is within the range of currently approved and commonly used cytotoxic chemotherapeutic agents; and (b)&#160;raising subsequent net equity proceeds of at least $20,000. The Company may request an additional $5,000 of gross proceeds between October&#160;1, 2022 and December&#160;31, 2022, with funding, subject to the approval of Avenue&#x2019;s Investment &lt;/div&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Committee. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;Up to $3,000 of the principal amount of the Avenue Loan outstanding may be converted, at the option of Avenue, into shares of the Company&#x2019;s common stock at a conversion price of $11.98 per share. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;In connection with the Avenue Loan, the Company issued to Avenue a warrant (the &#x201c;Avenue Warrant&#x201d;) to purchase 127,755 shares of common stock at an exercise price per share equal to $0.01. The Avenue Warrant is exercisable until August 31, 2026. &lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Company will make monthly interest-only payments during the first fifteen months of the term of the Avenue Loan, which could be increased to up to twenty-four months upon the achievement of specified performance milestones. Following the interest-only period, the Company will make equal monthly payments of principal plus interest until the maturity date, when all remaining principal outstanding and accrued interest must be paid. If the Company prepays the Avenue Loan, it will be required to pay (a)&#160;a prepayment fee of 3% if the Avenue Loan is prepaid during the interest-only period; and (b)&#160;a prepayment fee of 1% if the Avenue Loan is prepaid after the interest-only period. The Company must make an incremental final payment equal to 4.25% of the aggregate funding. &lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Company paid an aggregate commitment fee of $150 at closing. Upon funding a second tranche of the Avenue Loan, the Lender will earn a 1.0% fee on the $5,000 of incremental committed capital, for a total commitment fee of $200. &lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;The Avenue Loan Agreement requires the Company to make and maintain representations and warranties and other agreements that are customary in loan agreements of this type. The Avenue Loan Agreement also contains customary events of default, including &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-payment&lt;/div&gt; of principal or interest, violations of covenants, bankruptcy and material judgments. &lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;The Company determined that the embedded conversion option associated with the Avenue Loan was not required to be bifurcated. The Company determined that the Avenue Warrant met the criteria to be equity-classified. The $637 value of the final payment was treated as original issue discount. The $1,171 relative fair value of the Avenue Warrant was credited to Additional Paid in Capital while it was debited as debt discount. Of the $563 of cash issuance costs, $519 was allocated to the Avenue Loan and was recorded as debit discount, while $44 was allocated to the Avenue Warrant and was debited to Additional Paid in Capital. Of the $2,327 of aggregate debt discount, $1,909 was allocated to the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-convertible&lt;/div&gt; portion of the Avenue Loan, while $418 was allocated to the convertible portion of the Avenue Loan. Aggregate debt discount amortization of $323 was recorded during the year ended December&#160;31, 2021, including $265 related to the &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-convertible&lt;/div&gt; portion of the Avenue Loan and $58 related to the convertible portion of the Avenue Loan. The Company also determined that the convertible portion of the Avenue Loan did not include a beneficial conversion feature, because the effective conversion price exceeded the commitment&#160;&lt;/div&gt;  &lt;div style="font-size: 6pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-size: 6pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"/&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;date market price of the Company&#x2019;s common stock.

Subject to the terms and conditions of the sales agreement, Cantor Fitzgerald is required to use commercially reasonable efforts, consistent with its normal trading and sales practices, applicable state and federal law, rules and regulations and the rules of the Nasdaq Stock Market, to sell Placement Shares from time to time based upon the Company&#x2019;s instructions, including any price, time or size limits specified by the Company.

As a result of the public offering, the conversion price&#160;of the Company&#x2019;s Series E and Series &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;E-1&lt;/div&gt; &lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;Convertible &lt;/div&gt;Preferred Stock &lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;was&lt;/div&gt; adjusted to $10.00 per share and the exercise price of the 2019 &lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;common stock warrants issued in 2019 to the holders of the Company&#x2019;s Series E and Series E-1 Convertible Preferred Stock &lt;/div&gt;&lt;/div&gt;was adjusted to $10.00 per share and neither instrument is subject to further price resets.

In a letter dated, June&#160;29, 2020, an attorney representing the Claimants made certain claims and threatened litigation against the Company. On or about July&#160;27, 2020, the Claimants filed a statement of claim with the American Arbitration Association against the Company. The Claimants sought payment of certain purported unpaid compensation amounts claimed to be due to them, in an approximate amount of $1,140 in the aggregate, as well as unspecified statutory damages under New York Labor Law, attorneys&#x2019; fees and costs, and statutory interest. The Claimants and the Company agreed to participate in &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;non-binding&lt;/div&gt; mediation of their dispute before a neutral mediator, which resulted in the arbitration proceedings being placed in abeyance pending the outcome of the mediation process. With the assistance of the neutral mediator and after careful consideration by the Company&#x2019;s board of directors following several weeks of negotiations, the Claimants and the Company agreed in &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;mid-May&lt;/div&gt; of 2021 to a confidential settlement of their dispute to avoid the expenses and distractions of further arbitration proceedings, with no admission of liability or wrongdoing on the part of the Company. While the Company had accrued for the full purported unpaid compensation amount of $1,140 as of December&#160;31, 2020, the Company ultimately paid less in full and final settlement of its dispute with both of the Claimants. As a result of the confidential settlement, the AAA Arbitration was dismissed with prejudice on June&#160;1, 2021. &lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="text-indent: 0px;;font-style:italic;display:inline;"&gt;medac Matter&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;"&gt; &lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;In April 2021, the Company issued an invoice for &#x20ac;1,000 (which currently converts to approximately $1,160) to medac GmbH, a privately held, multi-national pharmaceutical company based in Germany (&#x201c;medac&#x201d;), the Company&#x2019;s EU product distribution partner, for a milestone payment due under the License, Supply and Marketing Agreement (the &#x201c;License Agreement&#x201d;) dated December 10, 2018, between the Company and medac. Pursuant to the License Agreement, a milestone is due upon achieving positive efficacy in the FOCUS trial as defined by the FOCUS trial protocol. Per the trial protocol and associated Statistical Analysis Plan, positive efficacy is based on whether the Objective Response Rate (ORR) exceeds a prespecified threshold. A preliminary analysis of the FOCUS trial data based on 87% of enrolled patients was released on March&#160;31, 2021, and subsequently presented at the American Society of Clinical Oncology (ASCO) Annual Meeting held virtually from the 4th through the 8th of June 2021. Per that analysis, the ORR exceeded the prespecified threshold. While the final ORR is not yet known, given the magnitude by which the ORR exceeded the prespecified endpoint and the small number of patients yet to be assessed, the final ORR will be greater than the prespecified endpoint regardless of the responder status of the remaining patients. medac disagrees that the milestone is due and claims that a full clinical study report is required in addition to the existing ORR analysis. medac has not disputed the accuracy of the ORR analysis or underlying data, but simply asserts that a full clinical study report is required prior to payment. &lt;/div&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;While the Company disagrees with this interpretation, since medac has stated they do not intend to pay the invoice at this time, under revenue recognition criteria set out in ASC 606, the Company cannot recognize the revenue in the year ending December&#160;31, 2021. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"/&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;On October&#160;12, 2021, the Company notified medac in writing that it was terminating the License Agreement &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt; &lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;due to medac&#x2019;s nonpayment of the milestone payment due under the License Agreement, with the effective date of termination of the License Agreement being April&#160;12, 2022. medac disputed having an obligation to make a milestone payment under the Agreement and demanded withdrawal of the termination notice. The Company declined to withdraw the termination notice and, on December&#160;16, 2021, the Company initiated an arbitration proceeding pursuant to the dispute resolution provisions of the Agreement. The arbitration proceeding is moving forward with the parties agreeing to stay the arbitration for a finite period to pursue settlement discussions. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px; text-indent: 0px;;display:inline;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;On December 30, 2021, the Company received a letter from medac stating that, due to its failure to withdraw the termination notice, medac was terminating the License Agreement with immediate effect. In the letter, medac reserved its rights in full, including a purported claim for damages for wrongful termination. In a separate letter, medac agreed to orderly transition through February 28, 2022 in order to minimize the impact of any termination on patients and physicians. As a result of the early termination of the License Agreement, the Company revised its estimate of the contract life which resulted in an acceleration of&#160;&lt;/div&gt;$1,742 of revenue recognition associated with deferred revenue.&#160;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 18pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-weight:bold;display:inline;"&gt;&lt;div style="font-style: normal; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-style:italic;display:inline;"&gt;Officer Appointment &#x2013; Chief Executive Officer &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;On October&#160;1, 2020, Gerard Michel was appointed as the Company&#x2019;s new Chief Executive Officer and a Class&#160;I Director. Pursuant to an employment agreement dated as of August&#160;31, 2020 between the Company and Mr.&#160;Michel (the &#x201c;Employment Agreement&#x201d;), the term of Mr.&#160;Michel&#x2019;s employment began on October&#160;1, 2020.

A significant portion of the federal amount is subject to an annual limitation as low as $28 as a result of changes in the Company&#x2019;s ownership in May 2003, November 2016, and multiple dates throughout 2017, 2018, 2019 and 2021, as defined by Section&#160;382 of the United States Internal Revenue Code of 1986, as amended (the &#x201c;IRC&#x201d;), and &lt;/div&gt;&lt;/div&gt;  &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;the related income tax regulations. As a result of the limitations caused by the multiple ownership changes, approximately $204,458 of the total net operating loss carryforwards is expected to expire unutilized and will be unavailable to offset future federal taxable income. Approximately $72,940 of net operating loss carryforwards remains available to offset future federal taxable income, of which $1,737 will expire between 2022 and 2037 and $71,203 will have an unlimited carryforward period as a result of the Tax Cuts and Jobs Act. &lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;In addition, the Company&#x2019;s state net operating losses are also subject to annual limitations that generally follow the IRC Section&#160;382 provisions (with the exception of Connecticut), adjusted for each state&#x2019;s respective income apportionment percentages. As of December&#160;31, 2021, and 2020, the Company had net operating loss carryforwards for state and city income tax purposes between approximately $24,760 and $193,680 and between approximately $26,414 and $192,466, respectively, which expire through 2041. As a result of the Section&#160;382 limitations, approximately $191,914 and $176,137 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 $1,766 and $1,737 of net operating loss carryforwards, respectively, will be available to offset future state and city taxable income. As of December&#160;31, 2021 and 2020 the Company had a net operating loss carryforward for foreign income tax purposes of $27,951 and $30,880, respectively, which have indefinite carryforward periods. As of December&#160;31, 2021 and 2020, the Company had federal research and development tax credit carryforwards of approximately $5,833 and $5,458, respectively, which expire through 2041. As a result of the &lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;S&lt;/div&gt;ection 382 limitations, all but $721 of the tax credit carryforwards is expected to expire unutilized. &lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&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&#x2019;s valuation allowance increased by approximately $1,793 and $6,540 in 2021 and 2020, respectively. The change in valuation allowance is as follows: &lt;/div&gt;&lt;/div&gt; &lt;div style="font-size: 12pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&lt;div style="font-size: 12pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;&#160;&lt;/div&gt;&lt;/div&gt;

The CARES Act includes a variety of economic and tax relief measures intended to stimulate the economy, including loans for small businesses, payroll tax credits/deferrals, and corporate income tax relief. Due the Company&#x2019;s history of tax loss carryforwards and full valuation allowance, the CARES Act did not have a significant effect to the income tax provision, as the corporate income tax relief was directed towards cash taxpayers. &lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: Times New Roman; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%;"&gt;The Company complies with the provisions of ASC &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;740-10&lt;/div&gt; in accounting for its uncertain tax positions. ASC &lt;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;740-10&lt;/div&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;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;740-10,&lt;/div&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;div style="white-space: nowrap; letter-spacing: 0px; top: 0px;;display:inline;"&gt;740-10&lt;/div&gt; and therefore has not included a tabular roll forward of unrecognized tax benefits. As there are no uncertain tax positions recognized, interest and penalties have not been accrued. &lt;/div&gt;  &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&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&#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&#160;31, 2018; tax years ending December 31, 2018 through December 31, 2021 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&#160;31, 2017 (as Ireland has not initiated an audit of 2016 as of December&#160;31, 2021); tax years ending December&#160;31, 2017 through December&#160;31, 2021 remain open to examination. However, the Company&#x2019;s tax years December 31, 1998 through December 31, 2021 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;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"/&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; margin-top: 6pt; margin-bottom: 0pt; margin-left: 4%; text-indent: 0px;"&gt;&lt;div style="letter-spacing: 0px; top: 0px;;display:inline;"&gt;&lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt;The Company recognizes interest accrued related to unrecognized tax benefits and penalties, if incurred, as a component of income tax expense. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style="font-family: &amp;quot;Times New Roman&amp;quot;; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;"&gt; &lt;/div&gt;</us-gaap:IncomeTaxDisclosureTextBlock>
