These investments are valued at estimated fair value, with unrealized gains and losses&#13;reported as a separate component of stockholders&amp;#8217; equity in accumulated other comprehensive loss.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;Securities&#13;available for sale are evaluated periodically to determine whether a decline in their value is other than temporary. The term&#13;&amp;#8220;other than temporary&amp;#8221; is not intended to indicate a permanent decline in value. Rather, it means that the prospects&#13;for near term recovery of value are not necessarily favorable, or that there is a lack of evidence to support fair values equal&#13;to, or greater than, the carrying value of the security. Management reviews criteria such as the magnitude and duration of the&#13;decline, as well as the reasons for the decline, to predict whether the loss in value is other than temporary. Once a decline&#13;in value is determined to be other than temporary, the value of the security is reduced and a corresponding charge to earnings&#13;is recognized.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

We acquired all EGEN&amp;#8217;s right, title&#13;and interest in and to substantially all of the assets of EGEN, including cash and cash equivalents, patents, trademarks and other&#13;intellectual property rights, clinical data, certain contracts, licenses and permits, equipment, furniture, office equipment,&#13;furnishings, supplies and other tangible personal property. In addition, CLSN Laboratories assumed certain specified liabilities&#13;of EGEN, including the liabilities arising out of the acquired contracts and other assets relating to periods after the closing&#13;date.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;At&#13;the time of the acquisition, the total purchase price for the asset acquisition was up to $44.4 million, including potential future&#13;earnout payments of up to $30.4 million contingent upon achievement of certain earnout milestones set forth in the Asset Purchase&#13;Agreement. We paid approximately $3.0 million in cash after the expense adjustment and issued 241,590 shares of our common stock&#13;to EGEN. The shares of common stock were issued in a private transaction exempt from registration under the Securities Act, pursuant&#13;to Section 4 (2) thereof.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&lt;i&gt;Acquired&#13;In-process Research and Development&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;Acquired&#13;in-process research and development (IPR&amp;#38;D) consists of EGEN&amp;#8217;s drug technology platforms: TheraPlas and TheraSilence.&#13;The fair value of the IPR&amp;#38;D drug technology platforms was estimated to be $24.2 million as of the acquisition date. As of&#13;the closing of the acquisition, the IPR&amp;#38;D was considered indefinite lived intangible assets and will not be amortized. IPR&amp;#38;D&#13;is reviewed for impairment at least annually as of our third quarter ended September 30, and whenever events or changes in circumstances&#13;indicate that the carrying value of the assets might not be recoverable. On December 31, 2016, the Company determined one of its&#13;IPR&amp;#38;D assets related to its RNA delivery system was impaired and wrote off its fair value, incurring a non-cash charge of&#13;$1.4 million during 2016. During its annual assessments on September 30, 2017 and 2018, the Company determined its IPR&amp;#38;D asset&#13;related to its glioblastoma multiforme cancer (GBM) product candidate, originally fair valued at $9.4 million on the date of acquisition,&#13;was impaired and wrote this asset&amp;#8217;s carrying value down to $2.4 million collectively after those two assessments, incurring&#13;non-cash charges of $2.5 million and $4.5 million during 2017 and 2018, respectively. On September 30, 2018 and 2017, the Company&#13;evaluated its IPR&amp;#38;D of the ovarian cancer indication and concluded that it is not more likely than not that the asset is impaired.&#13;As no other indicators of impairment existed during the fourth quarter of 2018 and thus far in 2019, the Company concluded none&#13;of the other IPR&amp;#38;D assets were impaired at December 31, 2018 and June 30, 2019. The carrying amount of the ovarian cancer&#13;indication was $13.3 million at June 30, 2019 and December 31, 2018.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&lt;i&gt;Covenants&#13;Not To Compete&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;Pursuant&#13;to the EGEN Purchase Agreement, EGEN provided certain covenants (&amp;#8220;Covenant Not To Compete&amp;#8221;) to the Company whereby&#13;EGEN agreed, during the period ending on the seventh anniversary of the closing date of the acquisition on June 20, 2014, not&#13;to enter into any business, directly or indirectly, which competes with the business of the Company nor will it contact, solicit&#13;or approach any of the employees of the Company for purposes of offering employment. The Covenant Not to Compete, which was valued&#13;at approximately $1.6 million at the date of the EGEN asset acquisition, has a definitive life and is amortized on a straight-line&#13;basis over its life of 7 years. The Company recognized amortization expense of $56,829 in each of the three-month periods ended&#13;June 30, 2019 and 2018. The Company recognized amortization expense of $113,658 in each of the six-month periods ended June 30,&#13;2019 and 2018. The carrying value of the Covenant Not to Compete was $454,634, net of $1,136,580 in accumulated amortization expense,&#13;as of June 30, 2019. The carrying value of the Covenant Not to Compete was $568,929, net of $1,022,922 in accumulated amortization&#13;expense, as of December 31, 2018.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;The&#13;purchase price exceeded the estimated fair value of the net assets acquired by approximately $2.0 million which was recorded as&#13;Goodwill. Goodwill represents the difference between the total purchase price for the net assets purchased from EGEN and the aggregate&#13;fair values of tangible and intangible assets acquired, less liabilities assumed. Goodwill is reviewed for impairment at least&#13;annually as of our third quarter ended September 30 or sooner if we believe indicators of impairment exist. As of September 30,&#13;2018, we concluded that the Company&amp;#8217;s fair value exceeded its carrying value therefore &amp;#8220;it is not more likely than&#13;not&amp;#8221; that the Goodwill was impaired. As no other indicators of impairment existed during the fourth quarter of 2018 and&#13;thus far in 2019, the Company concluded it is &amp;#8220;not more likely than not&amp;#8221; Goodwill was impaired.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

The Company drew down $10 million upon closing&#13;of the Horizon Credit Agreement on June 27, 2018. The Company will use the funding provided under the Horizon Credit Agreement&#13;for working capital and advancement of its product pipeline.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;The&#13;obligations under the Horizon Credit Agreement are secured by a first-priority security interest in substantially all assets of&#13;Celsion other than intellectual property assets. The obligations will bear interest at a rate calculated based on one-month LIBOR&#13;plus 7.625%. The effective interest rate at December 31, 2018 was 9.98%. Payments under the loan agreement are interest only for&#13;the first twenty-four (24) months after loan closing, followed by a 24-month amortization period of principal and interest through&#13;the scheduled maturity date. At its option, the Company can prepay all the outstanding principal balance by prepaying the outstanding&#13;principal balance and an amount equal to 1-3% of the outstanding principal balance at that time, based on the amount of time prior&#13;to the maturity date of the notes.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;The&#13;Horizon Credit Agreement contains customary representations, warranties and affirmative and negative covenants including, among&#13;other things, covenants that limit or restrict Celsion&amp;#8217;s ability to grant liens, incur indebtedness, make certain restricted&#13;payments, merge or consolidate and make dispositions of assets. Upon the occurrence of an event of default under the Horizon Credit&#13;Agreement, the lenders may cease making loans, terminate the Horizon Credit Agreement, declare all amounts outstanding to be immediately&#13;due and payable and foreclose on or liquidate Celsion&amp;#8217;s assets that comprise the lenders&amp;#8217; collateral. The Horizon&#13;Credit Agreement specifies a number of events of default (some of which are subject to applicable grace or cure periods), including,&#13;among other things, non-payment defaults, covenant defaults, a material adverse effect on Celsion or its assets, cross-defaults&#13;to other material indebtedness, bankruptcy and insolvency defaults and material judgment defaults.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;As&#13;a fee in connection with the Horizon Credit Agreement, Celsion issued Horizon warrants exercisable for a total of 190,114 shares&#13;of Celsion&amp;#8217;s common stock (the &amp;#8220;Horizon Warrants&amp;#8221;) at a per share exercise price of $2.63. The Horizon Warrants&#13;are immediately exercisable for cash or by net exercise from the date of grant and will expire after ten years from the date of&#13;grant. Celsion registered the Horizon Warrants on Form S-3 (File No. 333 - 227236) filed with the Securities and Exchange Commission&#13;on September 7, 2018 and declared effective on October 10, 2018. The Company valued the Horizon Warrants issued using the Black-Scholes&#13;option pricing model and recorded a total of $507,116 as a direct deduction from the debt liability consistent with the presentation&#13;of a debt discount and are being amortized as interest expense using the effective interest method over the life of the loan.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;In&#13;connection with the Horizon Credit Agreement, the Company incurred financing fees and expenses totaling $175,000 which are recorded&#13;and classified as debt discount. In addition, the Company paid loan origination fees of $100,000 which has been recorded and classified&#13;as debt discount. These debt discount amounts totaling $782,116 are being amortized as interest expense using the effective interest&#13;method over the life of the loan. Also, in connection with each of the Horizon Credit Agreements, the Company is required to pay&#13;an end of term charge equal to 4.0% of the original loan amount at time of maturity. Therefore, these amounts totaling $400,000&#13;are being amortized as interest expense using the effective interest method over the life of the loan.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;During&#13;the three-month period ending June 30, 2019, the Company incurred $255,182 in interest expense and amortized $94,266 as interest&#13;expense for debt discounts and end of term charges in connection with the Horizon Credit Agreement. During the six-month period&#13;ending June 30, 2019, the Company incurred $508,471 in interest expense and amortized $191,724 as interest expense for debt discounts&#13;and end of term charges in connection with the Horizon Credit Agreement.

Aspire Capital has no right to require any sales by&#13;the Company but is obligated to make purchases from the Company as directed by the Company in accordance with the Aspire Purchase&#13;Agreement. There are no limitations on use of proceeds, financial or business covenants, restrictions on future funding, rights&#13;of first refusal, participation rights, penalties or liquidated damages in the Aspire Purchase Agreement. In consideration for&#13;entering into the Aspire Purchase Agreement, concurrently with the execution of the Aspire Purchase Agreement, the Company issued&#13;to Aspire Capital 164,835 shares of the Company&amp;#8217;s common stock (the &amp;#8220;Commitment Shares&amp;#8221;). The Company&amp;#8217;s&#13;policy is to record specific incremental costs directly attributable to an offering as a charge against the gross proceeds, if&#13;any, when the offering becomes effective. These Commitment Shares valued at $450,000 were recorded in September 2018 as costs&#13;of equity financing and charged against additional paid-in capital. The Aspire Purchase Agreement may be terminated by the Company&#13;at any time, at its discretion, without any cost to the Company. Aspire Capital has agreed that neither it nor any of its agents,&#13;representatives and affiliates shall engage in any direct or indirect short-selling or hedging of the Company&amp;#8217;s common stock&#13;during any time prior to the termination of the Aspire Purchase Agreement. Any proceeds from the Company receives under the Aspire&#13;Purchase Agreement are expected to be used for working capital and general corporate purposes. During 2018, the Company sold and&#13;issued an aggregate of 100,000 shares under the Aspire Purchase Agreement, receiving approximately $0.2 million. The Company sold&#13;and issued an aggregate of 1.9 million shares under the Aspire Purchase Agreement, receiving approximately $3.9 million during&#13;the first six months of 2019. Subsequent to June 30, 2019 and through August 13, 2019, the Company sold 300,000 shares under the&#13;Aspire Purchase Agreement, receiving approximately $0.5 million in additional gross proceeds.

Ltd. (Hisun)&#13;for the production of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt; in the China territory. In accordance with the terms of the agreement, Hisun will&#13;be responsible for providing all of the technical and regulatory support services, including the costs of all technical transfer,&#13;registration and bioequivalence studies, technical transfer costs, Celsion consultative support costs and the purchase of any&#13;necessary equipment and additional facility costs necessary to support capacity requirements for the manufacture of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt;.&#13;Celsion will repay Hisun for the aggregate amount of these development costs and fees commencing on the successful completion&#13;of three registration batches of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt;. Hisun is also obligated to certain performance requirements under&#13;the agreement. The agreement will initially be limited to a percentage of the production requirements of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt;&#13;in the China territory with Hisun retaining an option for additional global supply after local regulatory approval in the China&#13;territory. In addition, Hisun will collaborate with Celsion around the regulatory approval activities for ThermoDox&lt;sup&gt;&amp;#174;&#13;&lt;/sup&gt;with the China State Food and Drug Administration (CHINA FDA). During the first quarter of 2015, Hisun completed the successful&#13;manufacture of three registration batches of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt;.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;On&#13;January 18, 2013, we entered into a technology development contract with Hisun, pursuant to which Hisun paid us a non-refundable&#13;research and development fee of $5 million to support our development of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt; in mainland China, Hong Kong&#13;and Macau (the China territory). Following our announcement on January 31, 2013 that the HEAT study failed to meet its primary&#13;endpoint, Celsion and Hisun have agreed that the Technology Development Contract entered into on January 18, 2013 will remain&#13;in effect while the parties continue to collaborate and are evaluating the next steps in relation to ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt;&#13;, which include the sub-group analysis of patients in the Phase III HEAT Study for the hepatocellular carcinoma clinical indication&#13;and other activities to further the development of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt; for the Greater China market. The $5.0 million received&#13;as a non-refundable payment from Hisun in the first quarter 2013 has been recorded to deferred revenue and will continue to be&#13;amortized over the 10 -year term of the agreement, until such time as the parties find a mutually acceptable path forward on the&#13;development of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt; based on findings of the ongoing post-study analysis of the HEAT Study data.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 7.7pt; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;On&#13;July 19, 2013, the Company and Hisun entered into a Memorandum of Understanding to pursue ongoing cooperation for the continued&#13;clinical development of ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt; as well as the technology transfer relating to the commercial manufacture of&#13;ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt; for the China territory.

Our lead product candidate is ThermoDox&lt;sup&gt;&amp;#174;&lt;/sup&gt;, a proprietary heat-activated liposomal encapsulation&#13;of doxorubicin, currently in a Phase III clinical trial for the treatment of primary liver cancer (the &amp;#8220;OPTIMA Study&amp;#8221;).&#13;Second in our pipeline is GEN-1, a DNA-mediated immunotherapy for the localized treatment of ovarian cancer. These investigational&#13;products are based on our two platform technologies which, in addition, provide the basis for the future development of a range&#13;of therapeutics for difficult-to-treat forms of cancers. Our first platform is Lysolipid Thermally Sensitive Liposomes, a heat&#13;sensitive liposomal based dosage form that targets disease with known therapeutics in the presence of mild heat. Our second is&#13;TheraPlas, a novel nucleic acid-based treatment for local transfection of therapeutic plasmids. With these technologies we are&#13;working to develop and commercialize more efficient, effective and targeted oncology therapies that maximize efficacy while minimizing&#13;side-effects common to cancer treatments.&lt;/font&gt;&lt;/p&gt;</us-gaap:NatureOfOperations>

Leases will be classified as either finance or operating, with classification affecting the pattern of&#13;expense recognition in the income statement. This update also requires improved disclosures to help users of financial statements&#13;better understand the amount, timing and uncertainty of cash flows arising from leases. The update became effective for fiscal&#13;years beginning after December 15, 2018, including interim reporting periods within that reporting period. The FASB subsequently&#13;issued the following amendments to ASC Topic 842, which have the same effective date and transition date of January 1, 2019:&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;table cellspacing="0" cellpadding="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"&gt;&#13;&lt;tr style="font: 10pt Times New Roman, Times, Serif"&gt;&#13;    &lt;td style="width: 0.25in; font: 10pt Times New Roman, Times, Serif"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="vertical-align: top; width: 0.25in; font: 10pt Times New Roman, Times, Serif"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#9679;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="vertical-align: top; text-align: justify; font: 10pt Times New Roman, Times, Serif"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;ASU&#13;    No. 2018-10, &lt;i&gt;Codification Improvements to Topic 842, Leases&lt;/i&gt;, which amends certain narrow aspects of the guidance issued&#13;    in ASU 2016-02; and&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="font: 10pt Times New Roman, Times, Serif"&gt;&#13;    &lt;td style="text-align: justify; font: 10pt Times New Roman, Times, Serif"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="vertical-align: top; text-align: justify; font: 10pt Times New Roman, Times, Serif"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="vertical-align: top; text-align: justify; font: 10pt Times New Roman, Times, Serif"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="font: 10pt Times New Roman, Times, Serif"&gt;&#13;    &lt;td style="font: 10pt Times New Roman, Times, Serif"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="vertical-align: top; font: 10pt Times New Roman, Times, Serif"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#9679;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="vertical-align: top; text-align: justify; font: 10pt Times New Roman, Times, Serif"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;ASU&#13;    No. 2018-11, &lt;i&gt;Leases (Topic 842): Targeted Improvements&lt;/i&gt;, which allows for a transition approach to initially apply ASU&#13;    2016-02 at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the&#13;    period of adoption as well as an additional practical expedient for lessors to not separate non-lease components from the&#13;    associated lease component.&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;/table&gt;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;We&#13;adopted Topic ASC 842 effective January 1, 2019 and elected to apply the available practical expedients and implement internal&#13;controls to enable the preparation of financial information on adoption. We identified two of our leases consisting of the New&#13;Jersey corporate office lease and the Alabama lab facility lease as being subject to Topic ASC 842. The adoption of this standard&#13;resulted in the recognition of right-of-use assets of approximately $1.4 million, related operating lease liabilities of $1.5&#13;million and reduced other liabilities by approximately $0.1 million on the consolidated balance sheets as of January 1, 2019 with&#13;no material impact to the opening balance of retained earnings.

In addition, the amendments expanded the&#13;disclosure requirements on the analysis of stockholders&amp;#8217; equity for interim financial statements. In August and September&#13;2018, further amendments were issued to provide implementation guidance on adoption of the SEC rule and transition guidance for&#13;the new interim stockholders&amp;#8217; equity disclosure. We adopted this amended guidance in the first quarter of 2019. The adoption&#13;of this amended guidance resulted in us disclosing the Condensed Consolidated Statements of Changes in Stockholders&amp;#8217; Equity&#13;for the three-month and six-month periods ending June 30, 2019 and 2018.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;In&#13;January 2017, the FASB issued Accounting Standard Update No. 2017-01, &amp;#8220;Business Combinations (Topic 805): Clarifying the&#13;Definition of a Business,&amp;#8221; which clarifies the definition of a business with the objective of adding guidance to assist&#13;entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses.&#13;This guidance is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years,&#13;with early adoption permitted. The adoption of ASU 2017-01 did not have an impact on our financial statement or disclosures.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;In&#13;January 2017, the FASB issued Accounting Standard Update No. 2017-04, &amp;#8220;Intangibles-Goodwill and Other, Simplifying the Test&#13;for Goodwill Impairment,&amp;#8221; which eliminated Step &lt;i&gt;2&lt;/i&gt; from the goodwill impairment test. Under the revised test, an entity&#13;should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying&#13;amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit&amp;#8217;s&#13;fair value; however, the loss recognized should &lt;i&gt;not&lt;/i&gt; exceed the total amount of goodwill allocated to that reporting unit.&#13;This ASU is effective for any interim or annual impairment tests for fiscal years beginning after December 15, 2019, with early&#13;adoption permitted. The Company adopted this method for its impairment testing of goodwill during 2017 and 2018. Based on the&#13;Company&amp;#8217;s evaluation, the adoption of the ASU 2017-04 did not have any material impact on its consolidated financial statements&#13;or its disclosures.&lt;/font&gt;&lt;/p&gt;</us-gaap:NewAccountingPronouncementsAndChangesInAccountingPrinciplesTextBlock>

The three levels of inputs that may be used to measure fair value are as follows:&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 27.5pt; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 27.5pt; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;Level&#13;1: Quoted prices (unadjusted) or identical assets or liabilities in active markets that the entity has the ability to access as&#13;of the measurement date;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 27.5pt; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 27.5pt; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;Level&#13;2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted&#13;prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data; and&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 27.5pt; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 27.5pt; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;Level&#13;3: Significant unobservable inputs that reflect a reporting entity&amp;#8217;s own assumptions that market participants would use&#13;in pricing an asset or liability.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;Cash&#13;and cash equivalents, other current assets, accounts payable and other accrued liabilities are reflected in the condensed consolidated&#13;balance sheet at their approximate estimated fair values primarily due to their short-term nature. The fair values of securities&#13;available for sale is determined by relying on the securities&amp;#8217; relationship to other benchmark quoted securities and classified&#13;its investments as Level 2 items in both 2019 and 2018. There were no transfers of assets or liabilities between Level 1 and Level&#13;2 and no transfers in or out of Level 3 thus far in 2019 and during the year ended December 31, 2018. The changes in Level 3 liabilities&#13;were the result of changes in the fair value of the earn-out milestone liability included in earnings and in-process R&amp;#38;D.&#13;The earnout milestone liability is valued using a risk-adjusted assessment of the probability of payment of each milestone, discounted&#13;to present value using an estimated time to achieve the milestone (see Note 13 for significant unobservable inputs). The in-process&#13;R&amp;#38;D &amp;#8211; GBM is valued using a multi-period excess earnings method (see Note 8 for significant unobservable inputs).&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The table below summarizes assets and liabilities&#13;measured at fair value.

(Brandywine), a&#13;Delaware limited partnership for a 10,870 square foot premises located in Lawrenceville, New Jersey. In October 2011, the Company&#13;relocated its offices to Lawrenceville, New Jersey from Columbia, Maryland. The Lease had an initial term of 66 months. In late&#13;2015, Lenox Drive Office Park LLC, purchased the real estate and office building and assumed the Lease. This Lease was set to&#13;expire on April 30, 2017. In April 2017, the Company and the landlord amended the Lease effective May 1, 2017. The 1&lt;sup&gt;st&lt;/sup&gt;&#13;Lease Amendment extended the term of the agreement for an additional 64 months, reduced the premises to 7,565 square feet, reduced&#13;the monthly rent and provided four months free rent. The monthly rent ranged from approximately $18,900 in the first year to approximately&#13;$20,500 in the final year of the 1&lt;sup&gt;st&lt;/sup&gt; Lease Amendment. The Company also had a one-time option to cancel the lease as&#13;of the 40th month after the commencement date of the 1&lt;sup&gt;st&lt;/sup&gt; Lease Amendment and must provide the landlord notice by the&#13;28&lt;sup&gt;th&lt;/sup&gt; month of the lease. Effective January 9, 2019, the Company amended the current terms of the 1&lt;sup&gt;st&lt;/sup&gt; Lease&#13;Amendment to increase the size of the premises by 2,285 square feet to 9,850 square feet and also extended the lease term by one&#13;year to September 1, 2023. In conjunction with this 2nd Lease Amendment, we agreed to modify our one-time option to cancel the&#13;lease as of the end of August 2021 and we must provide notice to the landlord by the end of August 2020. The monthly rent will&#13;range from approximately $25,035 in the first year to approximately $27,088 in the final year of the 2&lt;sup&gt;nd&lt;/sup&gt; Lease Amendment.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;In&#13;connection with the EGEN Asset Purchase Agreement in June 2014, the Company assumed the existing lease with another landlord for&#13;an 11,500 square foot premises located in Huntsville Alabama. In January 2018, the Company and the Huntsville landlord entered&#13;into a new 60-month lease which reduced the premises to 9,049 square feet with rent payments of approximately $18,100 per month.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;As&#13;previously mentioned in Note 4, we adopted ASC Topic 842 on January 1, 2019 using the modified retrospective transition method&#13;for all lease arrangements at the beginning of the period of adoption. Results for reporting periods beginning January 1, 2019&#13;are presented under ASC 842, while prior period amounts were not adjusted and continue to be reported in accordance with our historic&#13;accounting under Topic 840, Leases. The standard had a material impact on our Consolidated Condensed Balance Sheet but had no&#13;impact on our consolidated net earnings and cash flows. The most significant impact of adopting ASC Topic 842 was the recognition&#13;of the right-of-use (ROU) asset and lease liabilities for operating leases, which are presented in the following three-line items&#13;on the Consolidated Condensed Balance Sheet: (i) operating lease right-of-use asset; (ii) current operating lease liabilities;&#13;and (iii) operating lease liabilities. Therefore, on date of adoption of ASC Topic 842, the Company recognized a ROU asset of&#13;$1.4 million, operating lease liabilities, current and non-current collectively, of $1.5 million and reduced other liabilities&#13;by approximately $0.1 million. We elected the package of practical expedients for leases that commenced before the effective date&#13;of ASC Topic 842 whereby we elected to not reassess the following: (i) whether any expired or existing contracts contain leases;&#13;(ii) the lease classification for any expired or existing leases; and (iii) initial direct costs for any existing leases. In addition,&#13;we have lease agreements with lease and non-lease components, and we have elected the practical expedient for all underlying asset&#13;classes and account for them as a single lease component. We have no finance leases. We determine if an arrangement is a lease&#13;at inception. We have operating leases for office space and research and development facilities. Neither of our leases include&#13;options to renew, however, one contains an option for early termination. We considered the option of early termination in measurement&#13;of right-of-use assets and lease liabilities and we determined it is not reasonably certain to be terminated. In connection with&#13;the 2&lt;sup&gt;nd&lt;/sup&gt; Lease Amendment for the New Jersey office lease in January 2019, the Company considered this as one modified&#13;lease and not as two separate leases. Therefore, in January 2019, the Company determined this lease was an operating lease and&#13;remeasured the ROU asset and lease liability. Therefore, the Company increased the ROU asset and operating lease liabilities by&#13;$0.4 million to $1.8 million and $1.9 million, respectively.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

The monthly rent ranged from approximately $18,900 in the first year to approximately $20,500 in the final year of the 1st Lease Amendment. The Company also had a one-time option to cancel the lease as of the 40th month after the commencement date of the 1st Lease Amendment and must provide the landlord notice by the 28th month of the lease. Effective January 9, 2019, we amended the current terms of the 1st Lease Amendment to increase the size of the premises by 2,285 square feet to 9,850 square feet and also extended the lease term by one year to September 1, 2023. In conjunction with this 2nd Lease Amendment, we agreed to modify our one-time option to cancel the lease as of the end of August 2021 and we must provide notice to the landlord by the end of August 2020. The monthly rent will range from approximately $25,035 in the first year to approximately $27,088 in the final year of the 2nd Lease Amendment.</us-gaap:LesseeOperatingLeaseOptionToExtend>

The Company has not generated significant revenue and have incurred&#13;significant net losses in each year since our inception. As of June 30, 2019, the Company has incurred approximately $282 million&#13;of cumulative net losses and we had approximately $21.8 million in cash, investment securities and interest receivable. We have&#13;substantial future capital requirements to continue our research and development activities and advance our product candidates&#13;through various development stages.

There can be no assurance&#13;that the Company will be able to commercialize its technology successfully or that profitability will ever be achieved.

text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;The&#13;Company has based its estimate on assumptions that may prove to be wrong. The Company may need to obtain additional funds sooner&#13;or in greater amounts than it currently anticipates. Potential sources of financing include strategic relationships, public or&#13;private sales of the Company&amp;#8217;s shares or debt, the sale of the Company&amp;#8217;s State of New Jersey net operating losses&#13;and other sources. If the Company raises funds by selling additional shares of common stock or other securities convertible into&#13;common stock, the ownership interest of existing stockholders may be diluted.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;&amp;#160;&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;Annually,&#13;the State of New Jersey enables approved technology and biotechnology businesses with New Jersey net operating tax losses the&#13;opportunity to sell these losses through the Technology Business Tax Certificate Program (the &amp;#8220;NOL Program&amp;#8221;), thereby&#13;providing cash to companies to help fund their operations. The Company determined it met the eligibility requirements of the NOL&#13;Program and filed its application with the New Jersey Economic Development Authority (NJEDA) in June 2018. In this application,&#13;the Company requested authorization of up to $12.5 million in tax benefits from its cumulative New Jersey net operating losses&#13;to be eligible for sale. In September 2018, the NJEDA notified the Company that its application received approval to transfer&#13;$11.1 million of tax benefits. In December 2018, the Company successfully transferred these approved tax benefits which resulted&#13;in the receipt of $10.4 million in net cash proceeds to the Company at the end of 2018. The Company has approximately $3.9 million&#13;in future tax benefits remaining under the NOL Program for future years subsequent to 2018. In June 2019, the Company filed an&#13;application under the NOL Program to transfer an additional $2.0 million of tax benefits.&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;font style="font: 10pt Times New Roman, Times, Serif"&gt;With&#13;$21.8 million in cash, investment securities and interest receivable at June 30, 2019 coupled with potential future sales of the&#13;Company&amp;#8217;s New Jersey NOL&amp;#8217;s and, as more fully described in Note 11, the remaining availability under the Capitol on&#13;Demand&amp;#8482; with JonesTrading Institutional Services LLC and the common stock purchase agreement with Aspire Capital Fund LLC,&#13;the Company believes it has sufficient capital resources to fund its operations into the first quarter of 2021. The Company will&#13;be required to obtain additional funding to continue development of its current product candidates within the anticipated time&#13;periods, if at all, and to continue to fund operations.&lt;/font&gt;&lt;/p&gt;</CLSN:FinancialConditionAndBusinessPlanTextBlock>
