    These interim condensed consolidated financial statements are
    unaudited and were prepared by the Company in accordance with
    generally accepted accounting principles in the United States of
    America (GAAP) and with the SEC&amp;#x2019;s instructions to Form
    &lt;font style="WHITE-SPACE: nowrap"&gt;10-Q&lt;/font&gt; and Article 10 of
    Regulation &lt;font style="WHITE-SPACE: nowrap"&gt;S-X.&lt;/font&gt; They

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

    On June&amp;#xA0;6, 2019, the Company entered into an agreement with
    two institutional investors, pursuant to which the investors agreed
    to transfer and surrender to the Company for cancellation of
    warrants to purchase 5,605 shares of the Company&amp;#x2019;s common
    stock (the &amp;#x201C;Series D Warrants&amp;#x201D;) and warrants to
    purchase 0.1&amp;#xA0;million shares of the Company&amp;#x2019;s common
    stock (the &amp;#x201C;Pre-Funded Series D Warrants&amp;#x201D;). Under the
    terms of the Purchase Agreement, the Company agreed to sell and
    issue to the investors 8% Senior Secured Promissory Notes in an
    aggregate principal amount of $2.0&amp;#xA0;million in full payment and
    satisfaction of the purchase price for the Series D Warrants and
    Pre-Funded Series D Warrants. This agreement was effective on
    July&amp;#xA0;15, 2019, upon the closing of the Company&amp;#x2019;s Private
    Placement discussed further in Note 9. The principal is recognized
    in Convertible notes payable, long-term on the Condensed
    Consolidated Balance Sheet.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On April&amp;#xA0;19, 2019, April&amp;#xA0;26, 2019, May&amp;#xA0;9, 2019 and
    May&amp;#xA0;23, 2019, the Company issued 8% senior secured notes
    (collectively, the &amp;#x201C;2019 Notes&amp;#x201D;) in the aggregate
    principal amount of $3.3&amp;#xA0;million, to two institutional
    investors. The 2019 Notes bore interest at the rate of 8%&amp;#xA0;per
    annum and were to mature on the six-month anniversary of issuance
    in each case. The 2019 Notes were not convertible. The 2019 Notes
    contained standard events of default and remedies and are secured
    by a lien on the Company&amp;#x2019;s assets. The 2019 Notes were
    exchanged as part of the recent equity financing discussed further
    in Note 9 and are no longer outstanding.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In March 2019, the Company exchanged all issued and outstanding
    shares of its Series D Preferred Stock (having an aggregate stated
    value of $1,160,000) and received $400,000 in cash proceeds in
    exchange for a senior secured promissory note (the &amp;#x201C;March
    2019 Note&amp;#x201D;) in the principal amount of $1,560,000. The March
    2019 Note bore interest at the rate of 8%&amp;#xA0;per annum, and were
    to mature on April&amp;#xA0;1, 2020, and was not convertible. The March
    2019 Note was exchanged as part of the recent equity financing
    discussed further in Note 9 and is no longer outstanding.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On June&amp;#xA0;4, 2018, July&amp;#xA0;21, 2018, August&amp;#xA0;29, 2018, and
    September&amp;#xA0;21, 2018, the Company issued 8% senior secured
    convertible notes (collectively, the &amp;#x201C;2018 Notes&amp;#x201D;) in
    the aggregate principal amount of $9.4&amp;#xA0;million to several
    institutional investors. The 2018 Notes bore interest at the rate
    of 8%&amp;#xA0;per annum and had maturity dates between December 2018
    and March 2021. The 2018 Notes were initially convertible and
    secured pursuant to a Security Agreement which created a first
    priority security interest in all of the personal property (other
    than Excluded Collateral as defined in the Security Agreement) of
    the Company of every kind and description, tangible or intangible,
    whether currently owned and existing or created or acquired in the
    future. In March 2019, the Company amended the June 2018,&amp;#xA0;July
    2018 and August 2018 Notes to make them non-convertible. There was
    no impact to the financial statements. In April 2019, the Company
    received notices of default from the investors in the 2018 Notes
    which resulted in a 25%, or $1.1&amp;#xA0;million, increase in
    principal and an increase in the interest rates from 8% to 18%. The
    2018 Notes were exchanged as part of the recent equity financing
    discussed further in Note 9 and are no longer outstanding.&lt;/p&gt;

    The accounting treatment of derivative financial instruments
    requires that the Company record financial instruments at their
    fair value as of the inception date of the agreement and at fair
    value as of each subsequent balance sheet date. Any change in fair
    value is recorded as &lt;font style="WHITE-SPACE: nowrap"&gt;non-operating,&lt;/font&gt; &lt;font style="WHITE-SPACE: nowrap"&gt;non-cash&lt;/font&gt; income or expense for each
    reporting period at each balance sheet date. The Company reassesses
    the classification of its derivative instruments at each balance
    sheet date. If the classification changes as a result of events
    during the period, the contract is reclassified as of the date of
    the event that caused the reclassification. As a result of issuing
    such instruments the Company has adopted a sequencing policy in
    accordance with ASC &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;815-40-35-12&lt;/font&gt;&lt;/font&gt;&lt;/font&gt; whereby all
    future instruments may be classified as a derivative liability with
    the exception of instruments related to share-based compensation
    issued to employees. However, the Company has recognized the Series
    E Preferred Stock and Series &lt;font style="WHITE-SPACE: nowrap"&gt;E-1&lt;/font&gt; Preferred Stock issued in July
    2019 and August 2019 as equity because the agreements related to
    the issuance of those instruments specifically state that the
    common shares underlying the Preferred Stock take priority in
    registration. Additionally, the Company has a sufficient number of
    authorized shares for the issuance of common shares upon the
    conversion of the Preferred Stock. The Company did not have
    sufficient authorized shares to settle the associated warrants and
    accordingly has classified such warrants as a liability in the
    accompanying financial statements.&lt;/p&gt;

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

    At September&amp;#xA0;30, 2019, the Company had a total of
    125,000&amp;#xA0;February 2018 Warrants outstanding. As discussed in
    Part II&amp;#x2014;Item 1 &amp;#x201C;Legal Proceedings&amp;#x201D; and in Note 12
    to the Company&amp;#x2019;s condensed consolidated financial statements
    contained in this Quarterly Report on Form 10-Q, the February 2018
    Warrants were surrendered pursuant to a settlement agreement
    entered into between the Company and the remaining holders of the
    February 2018 Warrants on April&amp;#xA0;18, 2019 and final payment
    under the settlement was made on July&amp;#xA0;16, 2019. The fair value
    of the outstanding warrants at September&amp;#xA0;30, 2019 and
    December&amp;#xA0;31, 2018 was determined by using option pricing
    models with the following assumptions:&lt;/p&gt;

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

    Delcath Systems, Inc. is an interventional oncology company focused
    on the treatment of primary and metastatic liver cancers. Our
    investigational product&amp;#x2014;Melphalan Hydrochloride for Injection
    for use with the Delcath Hepatic Delivery System
    (&amp;#x201C;Melphalan/HDS&amp;#x201D;)&amp;#x2014;is designed to administer
    high-dose chemotherapy to the liver while controlling systemic
    exposure and associated side effects. In Europe, our system is
    commercially available under the trade name Delcath Hepatic
    CHEMOSAT &lt;sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top"&gt;&amp;#xAE;&lt;/sup&gt; Delivery System
    for Melphalan (&amp;#x201C;CHEMOSAT&amp;#x201D;) where it has been used at
    major medical centers to treat a wide range of cancers of the
    liver.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Our clinical development program (&amp;#x201C;CDP&amp;#x201D;) for
    Melphalan/HDS is comprised of The FOCUS Clinical Trial for Patients
    with Hepatic Dominant Ocular Melanoma (the &amp;#x201C;FOCUS
    Trial&amp;#x201D;) a global registration clinical trial that is
    investigating objective response rate in mOM, and the ALIGN Trial,
    a global Phase 3 clinical trial for ICC (the &amp;#x201C;ALIGN

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

    These interim condensed consolidated financial statements are
    unaudited and were prepared by the Company in accordance with
    generally accepted accounting principles in the United States of
    America (GAAP) and with the SEC&amp;#x2019;s instructions to Form 10-Q
    and Article 10 of Regulation S-X. They include the accounts of all
    entities controlled by Delcath and all significant inter-company
    accounts and transactions have been eliminated in
    consolidation.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The preparation of interim condensed consolidated financial
    statements requires management to make assumptions and estimates
    that impact the amounts reported. These interim condensed
    consolidated financial statements, in the opinion of management,
    reflect all adjustments, consisting of normal recurring accruals,
    necessary for a fair presentation of the Company&amp;#x2019;s results of
    operations, financial position and cash flows for the interim
    periods ended September&amp;#xA0;30, 2019 and 2018; however, certain
    information and footnote disclosures normally included in our
    Annual Report have been condensed or omitted as permitted by GAAP.
    It is important to note that the Company&amp;#x2019;s results of
    operations and cash flows for interim periods are not necessarily
    indicative of the results of operations and cash flows to be
    expected for a full fiscal year or any interim period.&lt;/p&gt;

    A description of our significant accounting policies has been
    provided in Note 3 Summary of Significant Accounting Policies to
    the Consolidated Financial Statements included in the
    Company&amp;#x2019;s Annual Report filed for the fiscal year ended
    December&amp;#xA0;31, 2018.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
    &lt;b&gt;&lt;i&gt;Derivative Financial Instruments&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The accounting treatment of derivative financial instruments
    requires that the Company record financial instruments at their
    fair value as of the inception date of the agreement and at fair
    value as of each subsequent balance sheet date. Any change in fair
    value is recorded as non-operating, non-cash income or expense for
    each reporting period at each balance sheet date. The Company
    reassesses the classification of its derivative instruments at each
    balance sheet date. If the classification changes as a result of
    events during the period, the contract is reclassified as of the
    date of the event that caused the reclassification. As a result of
    issuing such instruments the Company has adopted a sequencing
    policy in accordance with ASC 815-40-35-12 whereby all future
    instruments may be classified as a derivative liability with the
    exception of instruments related to share-based compensation issued
    to employees. However, the Company has recognized the Series E
    Preferred Stock and Series E-1 Preferred Stock issued in July 2019
    and August 2019 as equity because the agreements related to the
    issuance of those instruments specifically state that the common
    shares underlying the Preferred Stock take priority in
    registration. Additionally, the Company has a sufficient number of
    authorized shares for the issuance of common shares upon the
    conversion of the Preferred Stock. The Company did not have
    sufficient authorized shares to settle the associated warrants and
    accordingly has classified such warrants as a liability in the
    accompanying financial statements.&lt;/p&gt;

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

    On September&amp;#xA0;30, 2019, the Company and holders of a majority
    of the Company&amp;#x2019;s Series&amp;#xA0;E and Series E-1 Convertible
    Preferred Stock entered into an amendment to those certain
    registration rights agreements, dated as of July&amp;#xA0;11, 2019
    (effective as of July&amp;#xA0;15, 2019) (the &amp;#x201C;July Registration
    Rights Agreement&amp;#x201D;), and August&amp;#xA0;15, 2019 (the
    &amp;#x201C;August Registration Rights Agreement&amp;#x201D;) between the
    Company and the holders signatory thereto (the
    &amp;#x201C;Amendment&amp;#x201D;). The Amendment extends the applicable
    deadline for having a registration statement declared effective by
    the Securities and Exchange Commission (the &amp;#x201C;SEC&amp;#x201D;)
    under certain circumstances from 75 days to 120 days following the
    date of the July Registration Rights Agreement.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On October&amp;#xA0;18, 2019, the Company and holders of a majority of
    the Company&amp;#x2019;s Series&amp;#xA0;E and Series E-1 Convertible
    Preferred Stock entered into a second amendment (the &amp;#x201C;Second
    Amendment&amp;#x201D;) to those certain registration rights agreements,
    dated as of July&amp;#xA0;11, 2019 (effective as of July&amp;#xA0;15, 2019)
    and August&amp;#xA0;15, 2019, in each case as amended on
    September&amp;#xA0;30, 2019, between the Company and the holders
    signatory thereto. The Second Amendment eliminates the deadline to
    file a pre-effective registration statement amendment within 10
    days of the Company&amp;#x2019;s receipt of comments from the SEC.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On October&amp;#xA0;29, 2019, the Company and holders of a majority of
    the Company&amp;#x2019;s Series&amp;#xA0;E and Series E-1 Convertible
    Preferred Stock and related warrants entered into a third amendment
    (the &amp;#x201C;Third Amendment&amp;#x201D;) to those certain registration
    rights agreements, dated as of July&amp;#xA0;11, 2019 (effective as of
    July&amp;#xA0;15, 2019) and August&amp;#xA0;15, 2019, in each case as
    previously amended on September&amp;#xA0;30, 2019 and October&amp;#xA0;18,
    2019, between the Company and the holders signatory thereto
    (collectively, the &amp;#x201C;Registration Rights Agreements&amp;#x201D;).
    The Third Amendment clarifies that the liquidated damages specified
    in Section&amp;#xA0;2(d) of the Registration Rights Agreements shall
    not be payable to any holder whose Registrable Securities, as
    defined in the Registration Rights Agreements, are fully registered
    on an effective registration statement on the Effectiveness Date,
    as defined in the Registration Rights Agreements.&lt;/p&gt;

    Also on October&amp;#xA0;29, 2019, the Company entered into a Waiver

    Master Fund LP and Rosalind Opportunities Fund I LP, holders of its
    Series E and Series E-1 Convertible Preferred Stock and related
    warrants (together, &amp;#x201C;Rosalind&amp;#x201D;) pursuant to which
    Rosalind has agreed, among other things, to waive compliance with
    certain specified terms and conditions under the Registration
    Rights Agreements and forbear from exercising certain of their
    rights and remedies related to certain defaults thereunder for the
    time periods indicated therein.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 18px"&gt;

    Pursuant to the Company&amp;#x2019;s obligations under the July 2019
    Private Placement and the August 2019 Private Placement, the
    Company presented a proposal for a reverse stock split at its
    Annual Meeting of Stockholders on September&amp;#xA0;17, 2019. On the
    same date, a majority of stockholders of the Company approved a
    proposal to approve and adopt an amendment to our Amended and
    Restated Certificate of Incorporation to effect a reverse stock
    split of our shares of common stock, $0.01 par value per share,
    issued and outstanding or reserved for issuance, at a specific
    ratio within a range from 1-for-50 to 1-for-1,200, inclusive, prior
    to the first anniversary of stockholder approval of the proposal,
    and to grant authorization to the Board of Directors to determine,
    in its sole discretion, whether to effect the reverse stock split,
    as well as its specific timing and ratio. Also on the same date,
    the Company&amp;#x2019;s Board of Directors adopted resolutions to
    effect as soon as reasonably practicable the reverse split of the
    issued and outstanding shares of the Common Stock at a ratio of
    1-for-100.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On October&amp;#xA0;17, 2019, the Company filed with the Secretary of
    State of the State of Delaware a Certificate of Amendment to the
    Company&amp;#x2019;s Amended and Restated Certificate of Incorporation
    (the &amp;#x201C;Charter Amendment&amp;#x201D;) to effect a reverse stock
    split of the issued and outstanding shares of the Company&amp;#x2019;s
    common stock, $0.01 par value per share, at a ratio of 1-for-100 to
    be effective as of October&amp;#xA0;22, 2019 at 8:30 a.m., New York
    City time (the &amp;#x201C;Reverse Stock Split&amp;#x201D;). The Charter
    Amendment did not change the par value or any other terms of the
    common stock.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On October&amp;#xA0;22, 2019, the Company filed with the Secretary of
    State of the State of Delaware a Certificate of Correction (the
    &amp;#x201C;Certificate of Correction&amp;#x201D;) to the Charter Amendment,
    rescinding the Charter Amendment, citing an inaccuracy in Article
    Third of the Charter Amendment, which states an effective time for
    the Reverse Stock Split of 8:30 a.m. New York City time on
    October&amp;#xA0;22, 2019. Such effective time was based upon the
    Company&amp;#x2019;s prior receipt, on October&amp;#xA0;17, 2019, of
    confirmation by the Financial Industry Regulatory Authority, Inc.
    (&amp;#x201C;FINRA&amp;#x201D;) that it had completed its review of the
    Reverse Stock Split, including the effective time, whereupon the
    Company undertook to effect the Reverse Stock Split by filing the
    Charter Amendment. On the evening of October&amp;#xA0;21, 2019,
    subsequent to the Company&amp;#x2019;s filing of the Charter Amendment
    and issuance of a press release on October&amp;#xA0;18, 2019 announcing
    the confirmation by FINRA, FINRA notified the Company&amp;#x2019;s
    counsel that it was rescinding its prior confirmation. The
    Certificate of Correction further provides that the Company is
    currently awaiting FINRA confirmation. When such confirmation is
    obtained, the Company intends to file a Certificate of Amendment
    effectuating the Reverse Stock Split.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Following FINRA&amp;#x2019;s completion of its review of the
    Company&amp;#x2019;s Reverse Stock Split, on December&amp;#xA0;24, 2019, the
    Company effected a reverse stock split at which time
    Delcath&amp;#x2019;s common stock began trading on the OTCQB on a
    one-for-seven hundred (1:700)&amp;#xA0;split-adjusted basis. All owners
    of record as of the open of the OTCQB market on December&amp;#xA0;24,
    2019 received one issued and outstanding share of Delcath common
    stock in exchange for seven hundred outstanding shares of Delcath
    common stock. No fractional shares were issued in connected with
    the reverse stock split. All fractional shares created by the
    one-for-seven hundred exchange were rounded up to the next whole
    share. The reverse stock split had no impact on the par value per
    share of Delcath common stock, which remains at $0.01. All current
    and prior period amounts related to shares, share prices and
    earnings per share, presented in the Company&amp;#x2019;s consolidated
    financial statements and the accompanying Notes have been restated
    to give retrospective presentation for the reverse stock split.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
    &lt;b&gt;&lt;i&gt;Preferred Stock conversions&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    From October&amp;#xA0;1, 2019 through November&amp;#xA0;14, 2019, the
    Company issued 5,286 shares of Common Stock to the holders of
    Series E and Series E-1 Preferred Stock pursuant to conversion
    notices submitted by the holders.&lt;/p&gt;
    &lt;/div&gt;

    On July&amp;#xA0;11, 2019, the Company and certain accredited investors
    entered into a securities purchase agreement pursuant to which the
    Company sold to investors an aggregate of 20,000 shares of Series E
    convertible preferred stock, par value $0.01 per share (the
    &amp;#x201C;Series E Preferred Stock&amp;#x201D;), at a price of $1,000 per

    number of shares of common stock of the Company, equal to the
    number of shares of common stock issuable upon conversion of the
    Series E Preferred Stock purchased by the investor (the &amp;#x201C;July
    2019 Private Placement&amp;#x201D;). The Company received gross proceeds
    from the July 2019 Private Placement of $20.0&amp;#xA0;million.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On August&amp;#xA0;19, 2019, the Company and certain accredited
    investors entered into a securities purchase agreement pursuant to
    which the Company sold to investors an aggregate of 9,510 shares of
    Series E-1 convertible preferred stock, par value $0.01 per share
    (the &amp;#x201C;Series E-1 Preferred Stock&amp;#x201D;) at a price of $1,000
    per share and a warrant (a &amp;#x201C;2019 Warrant&amp;#x201D;) to purchase
    a number of shares of common stock of the Company equal to the
    number of shares of common stock issuable upon conversion of the
    Series E-1 Preferred Stock purchased by the investor (the &amp;#x201C;August 2019
    Private Placement&amp;#x201D;). The Company received gross proceeds from
    the August 2019 Private Placement of $9.5&amp;#xA0;million.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Each share of Series E Preferred Stock and Series E-1 Preferred
    Stock (collectively, the &amp;#x201C;Preferred Stock&amp;#x201D;) is
    convertible at any time at the option of the holder into the number
    of shares of Common Stock determined by dividing the stated value
    by the conversion price of $23.04, subject to certain limitations
    and adjustments&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 0pt"&gt;
    (the &amp;#x201C;Conversion Price&amp;#x201D;). Except for certain
    adjustments, the holders of the Preferred Stock are entitled to
    receive dividends on shares of Preferred Stock equal (on an
    &amp;#x201C;as converted&amp;#x201D; basis) to and in the same form as
    dividends paid on shares of the Common Stock. Any such dividends
    that are not paid to the holders of the Preferred Stock will
    increase the stated value. No other dividends will be paid on
    shares of Preferred Stock. Each Warrant has an exercise price equal
    to $23.04, subject to adjustment in accordance with the terms of
    the Warrants (the &amp;#x201C;Exercise Price&amp;#x201D;), and are
    exercisable at any time beginning on the date that the Company
    effects a reverse stock split until 5:00 p.m. (NYC time) on the
    date that is five years following the date that the Company effects
    a reverse stock split.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Conversion Price and the Exercise Price may, upon each of
    (i)&amp;#xA0;the third trading day following the date that the Company
    effects a reverse stock split, (ii)&amp;#xA0;the date that the initial
    registration statement to be filed pursuant to the Registration
    Rights Agreement (as further discussed below) is declared effective
    by the United States Securities and Exchange Commission ( &amp;#x201C;SEC&amp;#x201D;), and (iii)&amp;#xA0;in the event that all of the
    registrable securities (as defined in the Registration Rights
    Agreement) are not then registered on an effective registration
    statement, the date that all of the shares underlying the Preferred
    Stock and Warrants may be sold pursuant to Rule 144, be reduced,
    and only reduced, to equal the lesser of (x)&amp;#xA0;the then
    effective Conversion Price or Exercise Price, as applicable, and
    (y)&amp;#xA0;90% of the average of the five daily volume weighted
    average prices of the Common Stock immediately prior to such dates.
    In the event of a reduction in the Exercise Price, the aggregate
    number of Warrant Shares shall be increased such that the aggregate
    Exercise Price of the Warrants on the day immediately following
    such reduction in the Exercise Price is equal to the aggregate
    Exercise Price immediately prior to such adjustment. In addition,
    from the date of issuance of the Preferred Stock and Warrants until
    such time that the Company&amp;#x2019;s Common Stock is listed or quoted
    on a national exchange, the Conversion Price and the Exercise Price
    are subject to price-based anti-dilution protections.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company received net proceeds after expenses of
    $26.5&amp;#xA0;million. As discussed further in Note 8, the Company
    exchanged $11.8&amp;#xA0;million of debt, interest and Series D
    Warrants for 11,500 shares of Series E Preferred Stock and related
    warrants. The Company also exchanged $0.1&amp;#xA0;million in accounts
    payables for 149 shares of Series E Preferred Stock and related
    warrants and issued 923 shares of Series E Preferred Stock and
    related Warrants to certain investors in exchange for a waiver of
    rights under exchange agreements signed in December 2018 and March
    2019. Of the net proceeds and equitized value received, the Company
    allocated an estimated fair value of $20.8&amp;#xA0;million to the 2019
    Warrants. As a result of the Series E Preferred Stock and Series
    E-1 Preferred Stock having an effective conversion price that was
    lower than the market price on the date of issuance, the Company
    has recognized a beneficial conversion feature of
    $18.3&amp;#xA0;million. Due to the Series E Preferred Stock and Series
    E-1 Preferred Stock being immediately convertible, the beneficial
    conversion feature was recognized in full as a deemed dividend.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
    &lt;i&gt;Series D Preferred Stock&lt;/i&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On November&amp;#xA0;5, 2018, the Company&amp;#x2019;s Board authorized the
    establishment of a new series of preferred stock designated as
    Series D Preferred Stock, $0.01 par value, the terms of which are
    set forth in the certificate of designations for such series of
    Preferred Stock. On March&amp;#xA0;29, 2019, the Company exchanged all
    issued and outstanding shares of its Series D Preferred Stock
    (having an aggregate stated value of $1,160,000) and received
    $400,000 in cash proceeds in exchange for the issuance of the March
    2019 Notes. Please see the discussion under Note 8 above.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 18px"&gt;

    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    During the nine months ended September&amp;#xA0;30, 2019 the Company
    issued 11,285 shares of the Company&amp;#x2019;s common stock pursuant
    to the exercise of Pre-Funded Series D Warrants that were issued in
    connection with the 2018 Notes discussed in Note 8 above.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
    &lt;b&gt;&lt;i&gt;Warrant Exchange&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In April 2019, the Company entered into an exchange agreement with
    an institutional investor with respect to warrants held by such
    investor (the &amp;#x201C;February 2018 Warrants&amp;#x201D;). The February
    2018 Warrants were issued to several institutional investors as
    part of the Company&amp;#x2019;s February 2018 sale of the
    Company&amp;#x2019;s common stock and the issuance of warrants to
    purchase common shares. Pursuant to the exchange agreement, the
    Company issued 92 shares of the Company&amp;#x2019;s common stock (the
    &amp;#x201C;Exchange Shares&amp;#x201D;) in exchange for the February 2018
    Warrants. The exchange resulted in a loss of approximately $6,000
    which is recognized in the statement of operations.&lt;/p&gt;

    The Company&amp;#x2019;s 2019 Equity Incentive Plan (the
    &amp;#x201C;Plan&amp;#x201D;) allows for grants in the form of incentive
    stock options, nonqualified stock options, stock units, stock
    awards, stock appreciation rights, and other stock-based awards.
    All of the Company&amp;#x2019;s officers, directors, employees,
    consultants and advisors are eligible to receive grants under the
    Plan. The maximum number of shares reserved for issuance under the
    Plan is 2,142. Options to purchase shares of common stock are
    granted at exercise prices not less than 100% of fair value on the
    dates of grant. As of September&amp;#xA0;30, 2019, the Plan had
    approximately 502 shares available for grant.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;

    At September&amp;#xA0;30, 2019, there was approximately
    $0.1&amp;#xA0;million of total unrecognized compensation expense
    related to non-vested share-based compensation awards under the
    plans for employee and board stock option grants. The cost is
    expected to be recognized over a weighted average period of 0.3
    years. For the three and nine months ended September&amp;#xA0;30, 2019,
    the Company recognized share-based compensation expense of
    approximately $70,000 and $203,000 in the statement of operations,
    respectively.&amp;#xA0;For the same periods in 2018, the Company
    recognized share-based compensation expense of
    approximately&amp;#xA0;$116,000 and income of $5,000 in the statement
    of operations, respectively.&lt;/p&gt;

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

    The Company recognizes right-of-use (&amp;#x201C;ROU&amp;#x201D;) assets and
    lease liabilities when it obtains the right to control an asset
    under a leasing arrangement with an initial term greater than
    twelve months. The Company leases its facilities under
    non-cancellable operating and financing leases.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company evaluates the nature of each lease at the inception of
    an arrangement to determine whether it is an operating or financing
    lease and recognizes the ROU asset and lease liabilities based on
    the present value of future minimum lease payments over the
    expected lease term. The Company&amp;#x2019;s leases do not generally
    contain an implicit interest rate and therefore the Company uses
    the incremental borrowing rate it would expect to pay to borrow on
    a similar collateralized basis over a similar term in order to
    determine the present value of its lease payments.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 6px"&gt;

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

    While we currently utilize third parties to manufacture some
    components of our product, we also have our own manufacturing
    operations for certain components of our product and assemble and
    package our products in Queensbury, New York. See the discussion in
    Part 1, Item&amp;#xA0;1 under the caption &amp;#x201C;Manufacturing and

    The accompanying financial statements have been prepared on a going
    concern basis, which contemplates the realization of assets and the
    satisfaction of liabilities in the normal course of business. As
    shown in the accompanying financial statements during the year
    ended December&amp;#xA0;31, 2018, the Company incurred net losses of
    $19.2&amp;#xA0;million and used $14.7&amp;#xA0;million of cash for its
    operating activities. These factors among others raise substantial
    doubt about the Company&amp;#x2019;s ability to continue as a going
    concern for a reasonable period of time.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company&amp;#x2019;s existence is dependent upon management&amp;#x2019;s
    ability to obtain additional funding sources or to enter into
    strategic alliances. Adequate additional financing may not be
    available to us on acceptable terms, or at all. If the Company is
    unable to raise additional capital and/or enter into strategic
    alliances when needed or on attractive terms, it would be forced to
    delay, reduce or eliminate our research and development programs or
    any commercialization efforts. There can be no assurance that the
    Company&amp;#x2019;s efforts will result in the resolution of the
    Company&amp;#x2019;s liquidity needs. If Delcath is not able to continue
    as a going concern, it is likely that holders of its Common Stock
    will lose all of their investment. The accompanying consolidated
    financial statements do not include any adjustments that might
    result should the Company be unable to continue as a going
    concern.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company anticipates incurring additional losses until such
    time, if ever, that it can generate significant sales. At
    December&amp;#xA0;31, 2018, management believed that its capital
    resources were adequate to fund operations through March 2019.
    Additional working capital will be required to continue
    operations.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 6px"&gt;

    Operations of the Company are subject to certain risks and
    uncertainties, including, among others, uncertainty of product
    development and clinical trial results; uncertainty regarding
    regulatory approval; technological uncertainty; uncertainty
    regarding patents and proprietary rights; comprehensive government
    regulations; limited commercial manufacturing, marketing or sales
    experience; and dependence on key personnel. See Note 15 of these
    notes to the Company&amp;#x2019;s audited consolidated financial
    statements relating to subsequent events.&lt;/p&gt;

    &lt;font size="2"&gt;The accounting and financial reporting policies of
    the Company conform to generally accepted accounting principles in
    the United States of America (&amp;#x201C;GAAP&amp;#x201D;). The preparation
    of consolidated financial statements in conformity with GAAP
    requires management to make assumptions and estimates that impact
    the amounts reported in the Company&amp;#x2019;s consolidated financial
    statements. The consolidated financial statements include the
    accounts of all entities controlled by Delcath. All significant
    inter-company accounts and transactions are eliminated.&lt;/font&gt;&lt;/p&gt;

    The Company considers investments with original maturities of three

    Company has deposits that exceed amounts insured by the Federal
    Deposit Insurance Corporation (&amp;#x201C;FDIC&amp;#x201D;), however, the
    Company does not consider this a significant concentration of

    In February 2010, the Company entered into an agreement to lease
    (Initial Lease) 8,629 square feet of office space at 810 Seventh
    Avenue, New York, NY with an option to expand an additional 8,629
    square feet. The term of the Initial Lease began in March, 2010. In
    September 2010, the Company exercised its option right under the
    Initial Lease and entered into an agreement to lease (Lease
    Amendment) an additional 8,629 square feet of office space. The
    term of the Lease Amendment began in January 2011 and will expire
    in March 2021. In addition, the Lease Amendment extends the term of
    the Initial Lease to March 2021. The Initial Lease and the Lease
    Amendment provide for annual rent of $1.0&amp;#xA0;million in 2015,
    $1.0&amp;#xA0;million in 2016, and $1.2&amp;#xA0;million in 2017-2020. As
    discussed in Note 9, the Company has sub-leased this office
    space.&lt;/p&gt;

    In August 2011, Delcath Systems Ltd. entered into an agreement of
    lease for an office and manufacturing facility located in the city
    of Galway, Ireland. This facility is approximately 19,200 square
    feet and is intended to be the location of Delcath&amp;#x2019;s European
    headquarters. The Lease is for a term of ten years, commencing
    August, 2011. The Lease provides for fixed annual lease amounts
    payable in advance in equal quarterly installments. The remaining
    annual lease amount is $0.2&amp;#xA0;million. Delcath Systems Ltd. is
    also required to pay for customary building operating expenses.
    Delcath Systems Ltd.&amp;#x2019;s payment obligations and performance of
    the Lease are guaranteed by Delcath. The Company has sub-leased a
    portion of this facility.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In September 2018, the Company entered into an amendment (the
    &amp;#x201C;1633 Sublease Amendment&amp;#x201D;) to a sub-lease agreement
    executed in March 2016 (the &amp;#x201C;1633 Sublease&amp;#x201D;) for
    approximately 6,877 square feet of office space at 1633 Broadway,
    New York, NY. The term began in April 2016 and under the terms of
    the 1633 Sublease Amendment is extended through February 2021 and
    provides for total annual base rent of $0.5&amp;#xA0;million.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In January 2019, the Company entered into an amendment (the
    &amp;#x201C;Park Road Lease Amendment&amp;#x201D;) to a lease agreement
    entered into in October 2018 (the &amp;#x201C;Park Road Lease&amp;#x201D;)
    for approximately 6,000 square feet of space located at 95-97 Park
    Road in Queensbury, New York. Under the terms of the Park Road
    Lease Amendment, the original two year term which began on
    October&amp;#xA0;31, 2018 was extended through November 2020 and
    provides for total annual base rent of $50,000 per year.&lt;/p&gt;

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

    As previously reported, on July&amp;#xA0;27, 2018, Hudson Bay Master
    Fund Ltd. filed a summons and complaint against the Company in the
    New York State Supreme Court, New York County alleging breaches by
    the Company of Hudson Bay&amp;#x2019;s rights of participation in future
    Company offerings granted in the September 2017 Securities Purchase
    Agreement between the Company and Hudson Bay and in the February
    2018 Securities Purchase Agreement among, inter alia, the Company
    and Hudson Bay. In terms of relief sought, Hudson Bay claimed both
    monetary damages (which it claims to be in excess of $1 million)
    and specific performance. The Company denied any liability with
    respect to the claims set forth in the lawsuit. As previously
    reported, on January&amp;#xA0;4, 2019, the Company was notified by its
    litigation counsel that on December&amp;#xA0;28, 2018, the Suit was
    dismissed with prejudice by the filing of a Stipulation for
    Discontinuance in the New York State Supreme Court, New York
    County.&lt;/p&gt;

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

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

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

    prices included in Level&amp;#xA0;1 that are observable for the asset
    or liability, either directly or indirectly. Level&amp;#xA0;2 inputs
    may include quoted prices for similar assets and liabilities in
    active markets, as well as inputs that are observable for the asset
    or liability (other than quoted prices), such as interest rates,
    foreign exchange rates, and yield curves that are observable at
    commonly quoted intervals.&lt;/p&gt;
    &lt;/td&gt;

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

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

    Transactions that are denominated in a foreign currency are
    remeasured into the functional currency at the current exchange
    rate on the date of the transaction. Any foreign
    currency-denominated monetary assets and liabilities are
    subsequently remeasured at current exchange rates, with gains or
    losses recognized as foreign exchange (losses)/gains in the
    statements of operations.&lt;/p&gt;

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

    As of December&amp;#xA0;31, 2018 and 2017 the Company had net operating
    loss carryforwards for U.S. federal income tax purposes of
    approximately $230.0&amp;#xA0;million and $211.3&amp;#xA0;million
    respectively. A significant portion of the federal amount is
    subject to an annual limitation as low as $27,500 as a result of
    changes in the Company&amp;#x2019;s ownership in May 2003,&amp;#xA0;November
    2016, and multiple dates throughout 2017 and 2018, as defined by
    Federal Internal Revenue Code Section&amp;#xA0;382 and the related
    income tax regulations. As a result of the limitations caused by
    the May 2003,&amp;#xA0;November 2016 and multiple 2017 and 2018
    ownership changes, approximately $208.1&amp;#xA0;million of the total
    net operating loss carryforwards is expected to expire unutilized
    and will be unavailable to offset future federal taxable income.
    Approximately $21.9&amp;#xA0;million of net operating loss
    carryforwards remains available to offset future federal taxable
    income, of which $1.7&amp;#xA0;million will expire between 2019 and
    2037 and $20.2&amp;#xA0;million will have an unlimited carryforward
    period as a result of the Tax Cuts and Jobs Act.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In addition, the Company&amp;#x2019;s state net operating losses are
    also subject to annual limitations that generally follow the
    federal Section&amp;#xA0;382 provisions (with the exception of
    Connecticut), adjusted for each state&amp;#x2019;s respective income
    apportionment percentages. As of December&amp;#xA0;31, 2018 and 2017,
    the Company had net operating loss carryforwards for state and city
    income tax purposes between approximately $27.3&amp;#xA0;million and
    $167.3&amp;#xA0;million and between approximately $27.3&amp;#xA0;million
    and $150.3&amp;#xA0;million, respectively, which expire through 2038.
    As a result of the 382 limitations, approximately
    $157.2&amp;#xA0;million and $141.5&amp;#xA0;million of New York State and
    New York City net operating losses are expected to expire
    unutilized and will be unavailable to offset future taxable income.
    Approximately $10.1&amp;#xA0;million and $10.1&amp;#xA0;million of net
    operating loss carryforwards, respectively, will be available to
    offset future state and city taxable income. As of
    December&amp;#xA0;31, 2018 and 2017 the Company had a net operating
    loss carryforward for foreign income tax purposes of
    $25.2&amp;#xA0;million and $25.0&amp;#xA0;million, respectively, which have
    indefinite carryforward periods. As of December&amp;#xA0;31, 2018 and
    2017, the Company had federal research and development tax credit
    carryforwards of approximately $5.0&amp;#xA0;million and
    $4.3&amp;#xA0;million respectively, which expire through 2038. As a
    result of the section 382 limitations, all but $0.2&amp;#xA0;million of
    the tax credit carryforwards is expected to expire unutilized.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 6px"&gt;

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

    On December&amp;#xA0;22, 2017, the United States enacted the Tax Cuts
    and Jobs Act (the &amp;#x201C;Act&amp;#x201D;). The Act, which is also
    commonly referred to as &amp;#x201C;U.S. tax reform&amp;#x201D;,
    significantly changes U.S. corporate income tax laws by, among
    other provisions, reducing the maximum U.S. corporate income tax
    rate from 35% to 21% starting in 2018. During the year ended
    December&amp;#xA0;31, 2017, the Company reduced deferred tax assets by
    a provisional amount of $143,500, offset by a corresponding
    reduction to its valuation allowance, as a result of the
    re-measurement of deferred tax assets and liabilities from its 34%
    effective rate under existing law to the new lower statutory rate
    of 21%. The Company finalized its accounting of the effects of tax
    reform in 2018, which resulted in insignificant adjustments.&lt;/p&gt;

    The Act also requires a mandatory one-time inclusion of the
    deferred foreign income of controlled foreign corporations. The
    one-time transition tax is based on Delcath&amp;#x2019;s total post-1986
    earnings and profits (E&amp;amp;P) for which the Company has previously
    deferred from U.S. income taxes. During the year ended
    December&amp;#xA0;31, 2017, the Company&amp;#x2019;s reasonable estimate
    resulted in no provisional amount for the one-time transition tax
    liability, as the Company&amp;#x2019;s international subsidiaries are
    expected to have a cumulative deficit in E&amp;amp;P. As the
    Company&amp;#x2019;s international subsidiaries have a cumulative
    deficit in earnings and profits, the Company did not anticipate
    being affected by the mandatory inclusion provisions of the Act.
    The Company finalized its calculation of the total post-1986
    foreign E&amp;amp;P (including deficits) for these foreign subsidiaries
    during 2018 and was not impacted by the mandatory inclusion
    provisions of the Act.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On December, 22, 2017, Staff Accounting Bulletin 118 was issued due
    to the complexities involved in accounting for the recently enacted
    Act. SAB 118 requires the Company to include in its financial
    statements a reasonable estimate of the impact of the Act on
    earnings to the extent such estimate has been determined.
    Accordingly, the U.S. provision for income tax for
    December&amp;#xA0;31, 2017 was based on the reasonable estimate
    guidance provided by SAB 118. The Company finalized the impact from
    the Act and recorded insignificant adjustments.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company complies with the provisions of ASC 740-10, Income
    Taxes, in accounting for its uncertain tax positions. ASC 740-10
    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 740-10, 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 740-10 and therefore has not included a tabular
    rollforward of unrecognized tax benefits. As there are no uncertain
    tax positions recognized, interest and penalties have not been
    accrued.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company is subject to income tax in the U.S., as well as
    various state and international jurisdictions. The Company has not
    been audited by any state tax authorities in connection with income
    taxes. The Company has not been audited by international tax
    authorities or any states in connection with income taxes. The
    Company&amp;#x2019;s New York State tax returns have been subject to
    annual desk reviews which have resulted in insignificant
    adjustments to the related franchise tax liabilities and credits.
    The Company is no longer subject to federal and state examination
    for tax years ending prior to December&amp;#xA0;31, 2015; tax years
    ending December&amp;#xA0;31, 2015 through December&amp;#xA0;31, 2018 remain
    open to examination. The Republic of Ireland is the Company&amp;#x2019;s
    only significant foreign jurisdiction. The Company is no longer
    subject to Ireland tax examination for tax years ending prior to
    December&amp;#xA0;31, 2014 (as Ireland has not initiated an audit of
    2013 as of December&amp;#xA0;31, 2018); tax years ending
    December&amp;#xA0;31, 2014 through December&amp;#xA0;31, 2018 remain open
    to examination. However, the Company&amp;#x2019;s tax years
    December&amp;#xA0;31, 1998 through December&amp;#xA0;31, 2018 generally
    remain open to adjustment for all federal, state and foreign tax
    matters until its net operating loss and tax credit carryforwards
    are utilized or expire prior to utilization, and the applicable
    statutes of limitation have expired in the utilization year. The
    federal and state tax authorities can generally reduce a net
    operating loss (but not create taxable income) for a period outside
    the statute of limitations in order to determine the correct amount
    of net operating loss which may be allowed as a deduction against
    income for a period within the statute of limitations.&lt;/p&gt;

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

    In May 2014, the Financial Accounting Standards Board
    (&amp;#x201C;FASB&amp;#x201D;) issued Accounting Standards Update
    (&amp;#x201C;ASU&amp;#x201D;) 2014-09, Revenue from Contracts with Customers,
    that updates the principles for recognizing revenue. The core
    principle of the guidance is that an entity should recognize
    revenue to depict the transfer of promised goods or services to
    customers in an amount that reflects the consideration to which the
    entity expects to be entitled in exchange for those goods or
    services. ASU 2014-09 also amends the required disclosures of the
    nature, amount, timing and uncertainty of revenue and cash flows
    arising from contracts with customers. ASU 2014-09 is effective for
    the Company beginning in its fiscal year 2018, and may be applied
    retrospectively to all prior periods presented or through a
    cumulative adjustment to the opening retained earnings balance in
    the year of adoption. The Company has adopted this guidance.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In June 2016, the FASB issued ASU 2016-15, Statement of Cash Flows
    (Topic 230), which is intended to reduce diversity in practice in
    how certain transactions are classified in the statement of cash
    flows. The ASU is effective for public companies for fiscal years
    beginning after December&amp;#xA0;15, 2017, and interim periods within
    those fiscal years. Early adoption was permitted, including interim
    periods within those fiscal years provided that those electing
    early adoption must adopt all of the amendments in the same period.
    The guidance requires application using a retrospective transition
    method. The Company has adopted this guidance.&lt;/p&gt;

    In October 2016, the FASB issues ASU 2016-16 which simplifies the
    income tax consequences of intra-entity transfers other than
    inventory. Prior to ASU 2016-16, GAAL prohibited the recognition of
    current and deferred income taxes for intra-entity asset transfers
    until the asset has been sold to an outside party. ASU 2016-16
    eliminates this prohibition for intra-entity transfers of assets
    other than inventory but retains the prohibition for intra-entity
    transfers of inventory. This standard is effective go r public
    entities for fiscal years beginning after December&amp;#xA0;15, 2017.
    The Company has adopted this guidance. The adoption did not have a
    material impact on the Company&amp;#x2019;s consolidated financial
    statements.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In November 2016, the FASB issued ASU 2016-18, Statement of Cash
    Flows (Topic 230): Restricted Cash, which requires that the
    statement of cash flows explain the change during the period in the
    total of cash, cash equivalents, and amounts generally described as
    restricted cash or restricted cash equivalents. Entities are also
    required to reconcile such total to amounts on the balance sheet
    and disclose the nature of the restrictions. ASU 2016-18 is
    effective for fiscal years beginning after December&amp;#xA0;15, 2017
    and interim periods within those fiscal years, and early adoption
    was permitted. The Company adopted this standard.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 18px"&gt;
    &amp;#xA0;&lt;/p&gt;

    &lt;b&gt;&lt;i&gt;SEC Disclosure Update and Simplification&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In August 2018, the SEC adopted the final rule under SEC Release
    No.&amp;#xA0;33-10532, Disclosure Update and Simplification, amending
    certain disclosure requirements that were redundant, duplicative,
    overlapping, outdated or superseded. In addition, the amendments
    expanded the disclosure requirements on the analysis of
    stockholders&amp;#x2019; equity for interim financial statements. Under
    the amendments, an analysis of changes in each caption of
    stockholders&amp;#x2019; equity presented in the balance sheet must be
    provided in a note or separate statement. The analysis should
    present a reconciliation of the beginning balance to the ending
    balance of each period for which a statement of comprehensive
    income is required to be filed. This final rule was effective on
    November&amp;#xA0;5, 2018. The adoption did not have a material impact
    on the Company&amp;#x2019;s consolidated financial statements.&lt;/p&gt;

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

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

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

    In order to help reduce operating costs and more appropriately
    align its office space with the size of its workforce, the Company
    entered into two sub-leases for office space at its 810 Seventh
    Avenue office. On May&amp;#xA0;22, 2014, the Company entered into a
    sub-lease agreement (&amp;#x201C;Sub-lease #1&amp;#x201D;) for approximately
    one-half of the office space at this location (&amp;#x201C;Suite
    3500&amp;#x201D;) resulting in a lease restructuring reserve of
    approximately $0.9&amp;#xA0;million. On August&amp;#xA0;18, 2014, the
    Company entered into a sub-lease agreement (&amp;#x201C;Sub-lease
    #2&amp;#x201D;) for the remaining one-half of office space at its 810
    Seventh Avenue office (&amp;#x201C;Suite 3505&amp;#x201D;) resulting in a
    lease restructuring reserve of approximately $0.7&amp;#xA0;million. As
    of December&amp;#xA0;31, 2018, the total remaining lease restructuring
    liability for its leased office space was approximately
    $0.4&amp;#xA0;million, of which approximately $0.2&amp;#xA0;million and
    $0.2&amp;#xA0;million were included in Accrued expenses and Other

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

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

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

    &lt;b&gt;&lt;i&gt;Inventories&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Inventories are valued at the lower of cost or market value using
    the first-in, first-out method.&amp;#xA0;The reported net value of
    inventory includes finished saleable products, work-in-process, and
    raw materials that will be sold or used in future periods.&amp;#xA0;The
    Company reserves for expired, obsolete, and slow-moving
    inventory.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
    &lt;b&gt;&lt;i&gt;Property, Plant and Equipment&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    Property, plant and equipment are recorded at cost, less
    accumulated depreciation. The Company provides for depreciation on
    a straight line basis over the estimated useful lives of the assets
    which range from three to seven years. Leasehold improvements will
    be amortized over the shorter of the lease term or the estimated
    useful life of the related assets when they are placed into
    service. The Company evaluates property, plant and equipment for
    impairment periodically to determine if changes in circumstances or
    the occurrence of events suggest the carrying value of the asset or
    asset group may not be recoverable. Maintenance and repairs are
    charged to operations as incurred. Expenditures which substantially
    increase the useful lives of the related assets are
    capitalized.&lt;/p&gt;

    &lt;b&gt;&lt;i&gt;Derivative Instrument Liability&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company accounts for derivative instruments in accordance with
    Accounting Standards Codification (&amp;#x201C;ASC&amp;#x201D;) 815,
    Derivatives and Hedging, which establishes accounting and reporting
    standards for derivative instruments and hedging activities,
    including certain derivative instruments embedded in other
    financial instruments or contracts and requires recognition of all
    derivatives on the balance sheet at fair value, regardless of the
    hedging relationship designation. Accounting for changes in the
    fair value of the derivative instruments depends on whether the
    derivatives qualify as hedge relationships and the types of
    relationships designated are based on the exposures hedged. At
    December&amp;#xA0;31, 2018 and 2017, the Company did not have any
    derivative instruments that were designated as hedges.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
    &lt;b&gt;&lt;i&gt;Fair Value Measurements&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company adheres to ASC 820, Fair Value Measurement, which
    defines fair value, establishes a framework for measuring fair
    value, and expands disclosures about fair value measurements. ASC
    820 applies to reported balances that are required or permitted to
    be measured at fair value under existing accounting pronouncements;
    accordingly, the standard does not require any new fair value
    measurements of reported balances.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    ASC 820 emphasizes that fair value is a market-based measurement,
    not an entity-specific measurement. Therefore, a fair value
    measurement should be determined based on the assumptions that
    market participants would use in pricing the asset or
    liability.&amp;#xA0;As a basis for considering market participant
    assumptions in fair value measurements, ASC 820 establishes a fair
    value hierarchy that distinguishes between market participant
    assumptions based on market data obtained from sources independent
    of the reporting entity (observable inputs that are classified
    within Levels 1 and 2 of the hierarchy) and the reporting
    entity&amp;#x2019;s own assumptions about market participant assumptions
    (unobservable inputs classified within Level&amp;#xA0;3 of the
    hierarchy).&lt;/p&gt;

    asset or liability, which is typically based on an entity&amp;#x2019;s

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

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

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

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

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

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

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

    In May 2014, the Financial Accounting Standards Board
    (&amp;#x201C;FASB&amp;#x201D;) issued Accounting Standards Update
    (&amp;#x201C;ASU&amp;#x201D;) 2014-09, Revenue from Contracts with Customers,
    that updates the principles for recognizing revenue. The core
    principle of the guidance is that an entity should recognize
    revenue to depict the transfer of promised goods or services to
    customers in an amount that reflects the consideration to which the
    entity expects to be entitled in exchange for those goods or
    services. ASU 2014-09 also amends the required disclosures of the
    nature, amount, timing and uncertainty of revenue and cash flows
    arising from contracts with customers. ASU 2014-09 is effective for
    the Company beginning in its fiscal year 2018, and may be applied
    retrospectively to all prior periods presented or through a
    cumulative adjustment to the opening retained earnings balance in
    the year of adoption. The Company has adopted this guidance.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In June 2016, the FASB issued ASU 2016-15, Statement of Cash Flows
    (Topic 230), which is intended to reduce diversity in practice in
    how certain transactions are classified in the statement of cash
    flows. The ASU is effective for public companies for fiscal years
    beginning after December&amp;#xA0;15, 2017, and interim periods within
    those fiscal years. Early adoption was permitted, including interim
    periods within those fiscal years provided that those electing
    early adoption must adopt all of the amendments in the same period.
    The guidance requires application using a retrospective transition
    method. The Company has adopted this guidance.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In October 2016, the FASB issues ASU 2016-16 which simplifies the
    income tax consequences of intra-entity transfers other than
    inventory. Prior to ASU 2016-16, GAAL prohibited the recognition of
    current and deferred income taxes for intra-entity asset transfers
    until the asset has been sold to an outside party. ASU 2016-16
    eliminates this prohibition for intra-entity transfers of assets
    other than inventory but retains the prohibition for intra-entity
    transfers of inventory. This standard is effective go r public
    entities for fiscal years beginning after December&amp;#xA0;15, 2017.
    The Company has adopted this guidance. The adoption did not have a
    material impact on the Company&amp;#x2019;s consolidated financial
    statements.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In November 2016, the FASB issued ASU 2016-18, Statement of Cash
    Flows (Topic 230): Restricted Cash, which requires that the
    statement of cash flows explain the change during the period in the
    total of cash, cash equivalents, and amounts generally described as
    restricted cash or restricted cash equivalents. Entities are also
    required to reconcile such total to amounts on the balance sheet
    and disclose the nature of the restrictions. ASU 2016-18 is
    effective for fiscal years beginning after December&amp;#xA0;15, 2017
    and interim periods within those fiscal years, and early adoption
    was permitted. The Company adopted this standard.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 18px"&gt;
    &amp;#xA0;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 0pt"&gt;
    &lt;b&gt;&lt;i&gt;SEC Disclosure Update and Simplification&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In August 2018, the SEC adopted the final rule under SEC Release
    No.&amp;#xA0;33-10532, Disclosure Update and Simplification, amending
    certain disclosure requirements that were redundant, duplicative,
    overlapping, outdated or superseded. In addition, the amendments
    expanded the disclosure requirements on the analysis of
    stockholders&amp;#x2019; equity for interim financial statements. Under
    the amendments, an analysis of changes in each caption of
    stockholders&amp;#x2019; equity presented in the balance sheet must be
    provided in a note or separate statement. The analysis should
    present a reconciliation of the beginning balance to the ending
    balance of each period for which a statement of comprehensive
    income is required to be filed. This final rule was effective on
    November&amp;#xA0;5, 2018. The adoption did not have a material impact
    on the Company&amp;#x2019;s consolidated financial statements.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;

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

    The Company currently operates in one business segment, which is
    the development and commercialization of Melphalan/HDS and
    CHEMOSAT. A single management team that reports to the CEO and
    President comprehensively manages the business. Accordingly, the
    Company does not have separately reportable segments.&lt;/p&gt;

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

    Since January&amp;#xA0;1, 2019, the Company has issued 11,285 shares
    pursuant to exercises of Pre-Funded Series D Warrants.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    As previously reported, in January&amp;#xA0;2019, the Company
    terminated Backstop Commitment Purchase Agreements with four
    institutional investors, by their mutual agreement. The Company and
    such institutional investors entered into Backstop Commitment
    Purchase Agreements in connection with a rights offering conducted
    by the Company that closed in September 2018 in which the Company
    proposed to raise up to $50&amp;#xA0;million by distributing, at no
    charge, to holders of its Common Stock non-transferable rights to
    subscribe for and purchase shares of the Company&amp;#x2019;s Common
    Stock at a price of $1,225 per share (the &amp;#x201C;Subscription
    Price&amp;#x201D;). Pursuant to the Backstop Commitment Purchase
    Agreements, such institutional investors agreed to purchase, at the
    Subscription Price, shares not issued in the rights offering
    following the expiration of the rights offering subscription
    period, subject to certain conditions, including the requirement
    that the closing price of a share of the Company&amp;#x2019;s
    Common Stock as reported by the OTCQB or higher market for each of
    the five business days immediately preceding a purchase exceeded
    the Subscription Price. The Backstop Commitment Purchase Agreements
    were terminated by mutual agreement of the parties thereto due to
    the fact that the closing price of the Company&amp;#x2019;s Common
    Stock had not exceeded the Subscription Price since October&amp;#xA0;1,
    2018 and, thus, the institutional investors had no obligation to
    purchase shares.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On March&amp;#xA0;29, 2019, the Company exchanged all of its Series D
    Preferred Stock (with a stated value of $1,160,000) and received
    $400,000 in proceeds and issued a senior secured promissory note to
    an investor with a principal amount of $1,560,000. The note is due
    on April&amp;#xA0;1, 2020, bears interest at 8%&amp;#xA0;per annum and is
    nonconvertible.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On April&amp;#xA0;19, 2019, April&amp;#xA0;26, 2019, May&amp;#xA0;9, 2019 and
    May&amp;#xA0;23, 2019, the Company borrowed an aggregate
    $3.3&amp;#xA0;million from two institutional investors and issued
    promissory notes to the investors. The promissory notes have an
    aggregate principal amount of $3.3&amp;#xA0;million, bear interest at
    the rate of 8%&amp;#xA0;per annum and are due six months from the
    issuance of each note. The promissory notes are nonconvertible. The
    notes contain standard events of default and remedies therefor. The
    Company&amp;#x2019;s obligations under the promissory notes to the
    institutional investor are secured by a lien on the Company&amp;#x2019;s
    assets.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On June&amp;#xA0;6, 2019, the Company entered into an agreement with
    two institutional investors, pursuant to which the investors agreed
    to transfer and surrender to the Company for cancellation of 5,605
    Series D Warrants and 0.1&amp;#xA0;million Pre-Funded Series D
    Warrants. Under the terms of the Purchase Agreement, the investors
    agreed to defer the payment of the purchase price for the Series D
    Warrants and Pre-Funded Series D Warrants and, accordingly, the
    Company agreed to sell and issue to the investors 8% Senior Secured
    Promissory Notes in an aggregate principal amount of
    $2.0&amp;#xA0;million in full payment and satisfaction of the purchase
    price for the Series D Warrants and Pre-Funded Series D
    Warrants.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On December&amp;#xA0;24, 2019, the Company effected a reverse stock
    split at which time Delcath&amp;#x2019;s common stock began trading on
    the OTCQB on a one-for-seven hundred (1:700)&amp;#xA0;split-adjusted
    basis. All owners of record as of the open of the OTCQB market on
    December&amp;#xA0;24, 2019 received one issued and outstanding share of
    Delcath common stock in exchange for seven hundred outstanding
    shares of Delcath common stock. No fractional shares were issued in
    connected with the reverse stock split. All fractional shares
    created by the one-for-seven hundred exchange were rounded up to
    the next whole share. The reverse stock split had no impact on the
    par value per share of Delcath common stock, which remains at
    $0.01. All current and prior period amounts related to shares,
    share prices and earnings per share, presented in the
    Company&amp;#x2019;s consolidated financial statements and the
    accompanying Notes have been restated to give retrospective
    presentation for the reverse stock split.&lt;/p&gt;

    &lt;i&gt;Series D Preferred Stock&lt;/i&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On November&amp;#xA0;5, 2018, the Company&amp;#x2019;s Board authorized the
    establishment of a new series of preferred stock designated as
    Series D Preferred Stock, $0.01 par value, the terms of which are
    set forth in the certificate of designations for such series of
    Preferred Stock which was filed with the State of Delaware on
    November&amp;#xA0;5, 2018. On November&amp;#xA0;6, 2018 and
    November&amp;#xA0;30, 2018, the Company entered into a securities
    purchase agreements with an institutional investor which had
    purchased 101 shares of Series D Preferred Stock. At issuance, the
    Series D Preferred Stock would convert to 2,366 common shares.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On March&amp;#xA0;29, 2019, the Company exchanged all of its Series D
    Preferred Stock (with a stated value of $1,160,000) and received
    $400,000 in proceeds and issued a senior secured promissory note to
    an investor with a principal amount of $1,560,000. As a result, the
    Series D Preferred Stock is no longer outstanding.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
    &lt;b&gt;&lt;i&gt;Stock and Warrant Issuances&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

    &lt;i&gt;February 2018 Financing&lt;/i&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In February 2018, the Company completed the sale of 606 shares of
    its Common Stock, 109 pre-funded warrants and the issuance of
    warrants to purchase 1,429 common shares (the &amp;#x201C;February 2018
    Warrants&amp;#x201D;) pursuant to a placement agent agreement, with net
    proceeds after expenses of $4.3&amp;#xA0;million. The February 2018
    Warrants are exercisable one year after the anniversary date of
    their issuance. At December&amp;#xA0;31, 2018, the February 2018
    Warrants were exercisable at $7,000 per share with 273 warrants
    outstanding. The Company allocated an estimated fair value of
    $18.3&amp;#xA0;million to the February 2018 Warrants. The Company
    valued the February 2018 Warrants using the following inputs:
    exercise price of $7,000; contractual term of six years; volatility
    of 122.68% and risk-free rate of approximately one percent. Due to
    certain price protection features in the agreement, the February
    2018 Warrants were accounted for as a derivative liability at
    issuance and will be subsequently marked to market through the
    statement of operations.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 18px"&gt;

    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In September 2018, the Company completed the sale of 6,669 shares
    of its Common Stock, with net proceeds after expenses of
    approximately $7.0&amp;#xA0;million. The rights offering was made
    pursuant to a Registration Statement on Form S-1 that was made
    effective on August&amp;#xA0;3, 2018.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
    &lt;i&gt;December 2018 Warrant Exchange&lt;/i&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In December&amp;#xA0;2018, the Company entered into exchange agreements
    with several institutional investors with respect to their November
    2017 Warrants and February 2018 Warrants. The Company issued to the
    investors 1,179 shares of Common Stock (the &amp;#x201C;Exchange
    Shares&amp;#x201D;) in exchange for the Existing Warrants (the
    &amp;#x201C;Exchange&amp;#x201D;). The Exchange was made in reliance upon the
    exemption from registration provided by Section&amp;#xA0;3(a)(9) of the
    Securities Act of 1933, as amended.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
    &lt;i&gt;Pre-Funded Series D Warrant Exercises&lt;/i&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    5,379 Pre-Funded Series D Warrants were exercised during 2018.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In October 2018, the Company filed a registration statement on Form
    S-3 with the SEC, which was declared effective on December&amp;#xA0;21,
    2018 and allows the Company to offer and sell, from time to time in
    one or more offerings, up to $100.0&amp;#xA0;million shares of Common
    Stock, preferred stock, warrants, debt securities and stock
    purchase contracts as it deems prudent or necessary to raise
    capital at a later date. The Company has lost its eligibility to
    use Form S-3 due to the late filing of its Annual Report on Form
    10-K for the fiscal year ended December&amp;#xA0;31, 2018 and its late
    filing of its Quarterly Report on Form 10-Q for the fiscal quarter
    ended March&amp;#xA0;31, 2019.&lt;/p&gt;

    &lt;b&gt;&lt;i&gt;Stock Incentive Plans&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    As a result of the May&amp;#xA0;2, 2018 reverse stock split, the
    Company&amp;#x2019;s Stock Incentive Plan has no active grants and no
    further shares available to be granted.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    As previously reported, on February&amp;#xA0;1, 2019 the Board of
    Directors of the Company adopted the Company&amp;#x2019;s 2019 Equity
    Incentive Plan (the &amp;#x201C;2019 Plan&amp;#x201D;), pursuant to which
    2,142 shares of Common Stock of the Company are available for
    grants through February&amp;#xA0;1, 2029 to the Company&amp;#x2019;s
    employees, directors and consultants. On February&amp;#xA0;1, 2019,
    options to purchase 1,782 shares of Common Stock, at an exercise
    price of $196.70 per share, were granted under the 2019 Plan to
    certain executive officers and employees of the Company. The stock
    options are vesting over a period of one year commencing from the
    date of grant in twelve equal monthly increments commencing on the
    one month anniversary of the grant date. The stock options carry a
    ten year term and expire on February&amp;#xA0;1, 2029.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    For the years ended December&amp;#xA0;31, 2018 and December&amp;#xA0;31,
    2017, the Company recognized compensation income of
    $0.04&amp;#xA0;million and $0.05&amp;#xA0;million, respectively, related to
    stock options granted to employees.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    For the years ended December&amp;#xA0;31, 2018 and December&amp;#xA0;31,
    2017, the Company recognized compensation expense of approximately
    $0.1&amp;#xA0;million and $0.1&amp;#xA0;million, respectively, related to
    restricted stock granted to employees and consultants.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 18px"&gt;

    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    The Company issued warrants as part of its offerings in 2013, 2015,
    2016 and 2018 as well as part of its issuance of convertible notes
    in 2016 and 2018 and an exchange agreement in 2017. A summary of

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

    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    On June&amp;#xA0;4, 2018, July&amp;#xA0;21, 2018, August&amp;#xA0;29, 2018, and
    September&amp;#xA0;21, 2018, the Company issued 8% senior secured
    convertible notes (collectively, &amp;#x201C;the Notes&amp;#x201D;) to
    investors with aggregate principal of $9.4&amp;#xA0;million and
    maturity dates between December 2018 and March 2021. The Notes are
    secured pursuant to a Security Agreement which creates a first
    priority security interest in all of the personal property (other
    than Excluded Collateral (as defined in the Security Agreement) of
    the Company of every kind and description, tangible or intangible,
    whether currently owned and existing or created or acquired in the
    future. At December&amp;#xA0;31, 2018, the Notes were convertible at
    $1,225 per share subject to customary terms.&lt;/p&gt;

    In connection with the issuance of the Notes, the Company also
    issued 6,005 Series D Warrants with exercise prices ranging from
    $1,225&amp;#x2014;$2,800 and 0.1&amp;#xA0;million Pre-Funded Series D
    Warrants with a purchase price of $7.00. The warrants expire 5
    years from the date they could first be exercised. The provisions
    in the Series D Warrants and Pre-Funded Series D Warrants issued in
    June 2018 required the Company to initially account for the
    warrants as derivative liabilities. The warrants were valued at
    $5.1&amp;#xA0;million. As a result, the Company recognized a discount
    to debt of $2.3&amp;#xA0;million and a loss on issuance of a financial
    instrument of $2.8&amp;#xA0;million.&lt;/p&gt;

    &lt;i&gt;First Amendment to June 2018 Series D Warrants&lt;/i&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In July 2018, the Company and the investor from the June&amp;#xA0;2018
    transaction amended the June 2018 Pre-Funded Series D Warrants so
    that they are exercisable as of July&amp;#xA0;20, 2018 and the Company
    may redeem them at any time the Notes are no longer outstanding and
    the Company is not in default. The Company and the investor from
    the June 2018 transaction also amended the definition of a
    Fundamental Transaction in the June 2018 Warrants. This amendment
    resulted in $4.2&amp;#xA0;million related to the fair value of the June
    2018 Warrants being reclassified from a liability to equity.&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
    &lt;i&gt;Amendment to June 2018 and July 2018 Notes and Pre-Funded
    Warrants&lt;/i&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    In August 2018, the Company amended its June 2018 Notes and July
    2018 Notes such that the conversion price was reduced to $1,225,
    interest shall accrue until maturity, and the first
    $2.5&amp;#xA0;million and 50% of any subsequent financings shall be
    used to satisfy the Company&amp;#x2019;s obligations under the Notes.
    Effective the same date, the Company also amended its Pre-Funded
    Warrants such that the total number of June&amp;#xA0;2018 Pre-Funded
    Warrants was increased from 18,506 to 31,724 and the total number
    of July 2018 Pre-Funded Warrants was increased from 13,207 to
    22,640. This amendment was accounted for as an extinguishment of
    debt as the change in cash flows exceeded 10%. The original June
    2018 and July 2018 notes were written off and the amended June 2018
    and July 2018 Notes were recorded at fair value as of the date of
    this amendment. The Company recorded $1.1&amp;#xA0;million loss on debt
    extinguishment related to this amendment.&lt;/p&gt;

    &lt;font size="2"&gt;The accompanying financial statements have been
    prepared on a going concern basis, which contemplates the
    realization of assets and the satisfaction of liabilities in the
    normal course of business. As shown in the accompanying financial
    statements during the year ended December&amp;#xA0;31, 2018, the
    Company incurred net losses of $19.2&amp;#xA0;million and used
    $14.7&amp;#xA0;million of cash for its operating activities. These
    factors among others raise substantial doubt about the
    Company&amp;#x2019;s ability to continue as a going concern for a
    reasonable period of time.&lt;/font&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 6pt"&gt;
    &lt;font size="2"&gt;The Company&amp;#x2019;s existence is dependent upon
    management&amp;#x2019;s ability to obtain additional funding sources or
    to enter into strategic alliances. Adequate additional financing
    may not be available to us on acceptable terms, or at all. If the
    Company is unable to raise additional capital and/or enter into
    strategic alliances when needed or on attractive terms, it would be
    forced to delay, reduce or eliminate our research and development
    programs or any commercialization efforts. There can be no
    assurance that the Company&amp;#x2019;s efforts will result in the
    resolution of the Company&amp;#x2019;s liquidity needs. If Delcath is
    not able to continue as a going concern, it is likely that holders
    of its Common Stock will lose all of their investment. The
    accompanying consolidated financial statements do not include any
    adjustments that might result should the Company be unable to
    continue as a going concern.&lt;/font&gt;&lt;/p&gt;

    &lt;font size="2"&gt;The Company anticipates incurring additional losses
    until such time, if ever, that it can generate significant sales.
    At December&amp;#xA0;31, 2018, management believed that its capital
    resources were adequate to fund operations through March 2019.
    Additional working capital will be required to continue
    operations.&lt;/font&gt;&lt;/p&gt;
    &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 6px"&gt;
    &lt;font size="2"&gt;&amp;#xA0;&lt;/font&gt;&lt;/p&gt;

    &lt;font size="2"&gt;Operations of the Company are subject to certain
    risks and uncertainties, including, among others, uncertainty of
    product development and clinical trial results; uncertainty
    regarding regulatory approval; technological uncertainty;
    uncertainty regarding patents and proprietary rights; comprehensive
    government regulations; limited commercial manufacturing, marketing
    or sales experience; and dependence on key personnel. See Note 15
    of these notes to the Company&amp;#x2019;s audited consolidated
    financial statements relating to subsequent events.&lt;/font&gt;&lt;/p&gt;

    License fees and milestones received in exchange for the grant of a

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