ASU 2019-12 amends the approaches and methodologies in accounting for income taxes during interim periods and makes changes to certain income tax classifications. The new standard allows exceptions to the use of the incremental approach for intra-period tax allocation, when there is a loss from continuing operations and income or a gain from other items, and to the general methodology for calculating income taxes in an interim period, when a&#160;year-to-date loss exceeds the anticipated loss for the&#160;year. The standard also requires franchise or similar taxes partially based on income to be reported as income tax and the effects of enacted changes in tax laws or rates to be included in the annual effective tax rate computation from the date of enactment. Lastly, in any future acquisition, the Company would be required to evaluate when the step-up in the tax basis of goodwill is part of the business combination and when it should be considered a separate transaction. The Company adopted the standard as of January&#160;1, 2021 and has evaluated the effects of this standard and determined that the adoption did not have a material impact on the Company&#8217;s consolidated financial statements.</p></ix:nonNumeric></ix:continuation><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><a id="_aec31a2f_c16d_40bf_b98a_07520b40e8a0"></a><a id="Tc_qR2FbVBdaEy6yb1OL6hayg_1_2"></a><a id="Tc_Lzi38-vMF0iLQw4rgACGHw_2_2"></a><a id="Tc_70q6wAK_FUqnwccfY7IDOw_2_5"></a><a id="Tc_SjbHxS70IEqB18eiPBSi-g_2_8"></a><a id="Tc_yseaObOAmEOgHVDF4N_lRw_2_11"></a><a id="Tc_0hexgbX1f0efbF0lNVV0gA_3_0"></a><a id="Tc_kTvcbebmSU-Y-urSI-4zBA_4_0"></a><a id="Tc_uatAi9NCu0m7AhbPQsrbDg_4_2"></a><a id="Tc_wdcIuud7PEWSJAiSTYlgUg_4_5"></a><a id="Tc_iG1ObWhga0eX9iG9EW9H9w_4_8"></a><a id="Tc_jE4uiNsxiEqUm3UuyeK6fw_4_9"></a><a id="Tc_Er8tByHdJESB-kk0IP0ehA_4_11"></a><a id="Tc_t_HztU7GFEqbMKHtr53OXw_4_12"></a><a id="Tc_K5tIaIYiSUyTZCstK5AGXA_5_0"></a><a id="Tc_OfNKbw8jzUmUHFIrYNhiFA_5_6"></a><a id="Tc_bpMWXeHSr0eOtxpZpDHBIg_5_12"></a><a id="Tc_lZYLX4eHZEG9s3Cb01G48w_6_0"></a><a id="Tc_tXarYe0p6EyjXrgpUbUoGg_6_12"></a><a id="Tc_aurr0JAuYU-PXduYqzHgxw_7_0"></a><a id="Tc_TEFRZqLElUK6W-J8ga3nMA_8_0"></a><a id="Tc_fc_VtlPs40CAt68eO9MOlg_8_6"></a><a id="Tc_mKQ0nZ4bZ0KuoP-2mcpEqA_8_9"></a><a id="Tc_w-W5E9ro106IpYgopkl33Q_9_0"></a><a id="Tc_lE7PWIRgu0SfJXdjWXbdfw_9_2"></a><a id="Tc_FHCidK41J06omJG3zCYZaQ_9_5"></a><a id="Tc_NpLYfj1_WEKKX2251m5AiQ_9_6"></a><a id="Tc_7hEDzTo_DUGvXZjR_lBukg_9_8"></a><a id="Tc_q4Q7pRg0IUWLZbTc1OUFFQ_9_9"></a><a id="Tc_6dB97HYqJkCACTZV1CelYg_9_11"></a><a id="_9e9e3ab0_84b2_469d_b352_5c721fb18043"></a><a id="Tc_TTCPqHV7DUiuHaSzZaGc6Q_1_2"></a><a id="Tc_MN3ZBs35xk6OypNQMjD01w_2_2"></a><a id="Tc_p-Ja4CI680yLk-9TTN34cQ_2_5"></a><a id="Tc_zI08e07NRU2MIEu2P02omQ_2_8"></a><a id="Tc_yX9C_tBUHEeWv_3cb-fStQ_2_11"></a><a id="Tc_rN6OxYSVTE2MTzqiv-oTPA_3_0"></a><a id="Tc_O6ZHMaoumk-9uyTRMMWnzQ_4_0"></a><a id="Tc_GbrzkQQigEeppwwrDteP_A_4_2"></a><a id="Tc_518CFJ3430qNhj3W0U7aYA_4_5"></a><a id="Tc_rvjmGc6YeU2-VsccUYQkTw_4_8"></a><a id="Tc_-jJ9K3o9R0-2s01hUER63g_4_9"></a><a id="Tc_XBaxlgKeQ0O0DBpgmndHGQ_4_11"></a><a id="Tc_RLHlbhpVyk--ndKFj6jx7A_4_12"></a><a id="Tc_YznvBz7zoUeGlWFWG8WjVQ_5_0"></a><a id="Tc_veYftYEvhE28uBnWxg_mMQ_5_6"></a><a id="Tc_-JU1LBy6XkK6XSl8n8T9Eg_5_12"></a><a id="Tc_cJgWZ3patUqgDsQHSRCbRg_6_0"></a><a id="Tc_aANbgLhdH0OMJB9XOHfxLA_6_12"></a><a id="Tc_gHqWAP_JGEyUxaXbjXMSMA_7_0"></a><a id="Tc_g-m9WnHPuUm8ISFDr7f1Mw_8_0"></a><a id="Tc_t03HWC1mtkmnQnc6Y89sAw_8_6"></a><a id="Tc_9-3dWObm1UGEfV-shvcBmw_8_9"></a><a id="Tc_OEi-1y10Lkim3MWjFDyJKw_9_0"></a><a id="Tc_x9DsEzP3M0e4iwlMCtsg6w_9_6"></a><a id="Tc_Cu77XwCgz0uLyAUiKjUjEQ_9_9"></a><a id="Tc_twX-1Ix1lUO4uDUGZ_vYxA_10_0"></a><a id="Tc_8QDRFejRt0CjF_iV5wxU0Q_10_2"></a><a id="Tc_S_xwO9zshEilGN3wJFM12A_10_5"></a><a id="Tc_rHI1lyqoBU6KnB4wdrh6ug_10_6"></a><a id="Tc_NDLujYkXBkGmBGacyhasfQ_10_8"></a><a id="Tc_cwhBwLpDDkOFwEpeHlECJg_10_9"></a><a id="Tc_4Y03slXvgkOoXJB4dFXa1A_10_11"></a><ix:nonNumeric contextRef="Duration_1_1_2021_To_6_30_2021_UdWwmRkKw0K5WviQZ_RqRg" name="us-gaap:FairValueDisclosuresTextBlock" id="Tb__BwA_km60kCO-z2WjDpSsA" continuedAt="Tb__BwA_km60kCO-z2WjDpSsA_cont1" escape="true"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 12pt 0pt;">3.

The competitive award was granted by USAMRDC in collaboration with the Medical Technology Enterprise Consortium (&#8220;MTEC&#8221;), a 501(c)(3)&#160;biomedical technology consortium working in partnership with the Department of Defense (&#8220;DoD&#8221;). Under the contract, MTEC pays us a firm fixed fee based upon the achievement of certain milestones for conduct and completion of a Phase 1/2 study and research and development work on the replication-deficient adenovirus 5 (&#8220;RD-Ad5&#8221;) vector vaccine platform. For the six months ended June 30, 2021, we have recognized approximately $0.5 million of grant revenue under the contract.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In July&#160;2016, we signed a five-year contract with Biomedical Advanced Research and Development Authority (&#8220;BARDA&#8221;). The contract, as amended, has a total value of up to $133.7 million and is used to fund clinical development of NasoShield. Under the contract, BARDA pays us a fixed fee and reimburses certain costs for the research and development of an Ad5-vectored, protective antigen-based intranasal anthrax vaccine through cGMP manufacture and conduct of a Phase 1 clinical trial dose ranging assessment of safety and immunogenicity. The contract consists of an initial base performance period providing approximately $27.8 million in funding for the period July&#160;2016 through September&#160;2021. BARDA has seven options to extend the contract to fund certain continued development and manufacturing activities for the anthrax vaccine, including Phase 2 clinical trials. Each option, if exercised by BARDA, would provide additional funding ranging from approximately $1.1 million to $34.4 million for a three-year period beginning January&#160;2021. For the three and six months ended June 30, 2021, we have recognized approximately $0.1 million and $0.3 million, respectively, of grant revenue under the current BARDA contract. For the three and six months ended June 30, 2020, we recognized approximately $0.5 million and $2.1 million, respectively, of grant revenue under the current BARDA contract.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Critical Accounting Policies and Significant Judgment and Estimates</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Management&#8217;s Discussion and Analysis of Financial Condition and Results of Operations is based upon our unaudited consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. and the rules&#160;and regulations of the SEC for interim financial reporting.

Our cash, cash equivalents, restricted cash and short-term investments were $217.9 million at June&#160;30,&#160;2021. We believe, based on the operating cash requirements and capital expenditures expected for 2021 and 2022, our cash on hand and short-term investments at June&#160;30,&#160;2021, together with expected collections from our government sponsored contracts and tax refunds, are sufficient to fund operations for at least a twelve-month period from the issuance date of our June&#160;30,&#160;2021 consolidated financial statements.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">We have not generated any revenues from the sale of any products to date, and there is no assurance of any future revenues from product sales. Our sources of revenue have consisted of grant revenues under our arrangements with BARDA for the development of NasoShield, MTEC for a clinical trial and development work on T-COVID, and to a lesser degree from other licensing arrangements. We have incurred significant losses since we commenced operations. As of June&#160;30,&#160;2021, we had accumulated losses of $235.8 million since our inception. In addition, we have not generated positive cash flows from operations. We have had to rely on a variety of financing sources, including the issuance of debt and equity securities. As capital resources are consumed to fund our research and development activities, we may not have sufficient capital to fund our plan of operations. In order to address our capital needs, including our planned clinical trials, we must continue to actively pursue additional equity or debt financing, government funding, and monetization of our existing programs through partnership arrangements or sales to third parties.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In June&#160;2020, we were awarded $4.7 million from the U.S. Army Medical Research&#160;&amp; Development Command (&#8220;USAMRDC&#8221;) to fund our Phase 1/2 clinical trial of T-COVID. The competitive award was granted by USAMRDC in collaboration with the Medical Technology Enterprise Consortium (&#8220;MTEC&#8221;), a 501(c)(3)&#160;biomedical technology consortium working in partnership with the Department of Defense (&#8220;DoD&#8221;). Under the contract, MTEC pays us a firm fixed fee based upon the achievement of certain milestones for conduct and completion of a Phase 1/2 study and research and development work on the replication-deficient adenovirus 5 (&#8220;RD-Ad5&#8221;) vector vaccine platform. Through June&#160;30,&#160;2021, we have collected approximately $1.1 million in cash under the contract.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In July&#160;2016, we signed a five-year contract with BARDA. The contract, as amended, has a total value of up to $133.7 million and is used to fund clinical development of NasoShield. Under the contract, BARDA pays us a fixed fee and reimburses certain costs for the research and development of an Ad5-vectored, protective antigen-based intranasal anthrax vaccine through cGMP manufacture and conduct of a Phase 1 clinical trial dose ranging assessment of safety and immunogenicity. The contract consists of an initial base performance period providing approximately $27.8 million in funding for the period July&#160;2016 through September&#160;2021. BARDA has seven options to extend the contract to fund certain continued development and manufacturing activities for the anthrax vaccine, including Phase 2 clinical trials. Each option, if exercised by BARDA, would provide additional funding ranging from approximately $1.1 million to $34.4 million for a three-year period beginning January&#160;2021. Through June&#160;30,&#160;2021, we have collected approximately $25.5 million in cash under the current BARDA contract.</p></div><div style="clear:both;margin-bottom:30pt;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">21</p></div></div>

ASU 2019-12 amends the approaches and methodologies in accounting for income taxes during interim periods and makes changes to certain income tax classifications. The new standard allows exceptions to the use of the incremental approach for intra-period tax allocation, when there is a loss from continuing operations and income or a gain from other items, and to the general methodology for calculating income taxes in an interim period, when a&#160;year-to-date loss exceeds the anticipated loss for the&#160;year. The standard also requires franchise or similar taxes partially based on income to be reported as income tax and the effects of enacted changes in tax laws or rates to be included in the annual effective tax rate computation from the date of enactment. Lastly, in any future acquisition, the Company would be required to evaluate when the step-up in the tax basis of goodwill is part of the business combination and when it should be considered a separate transaction. The Company adopted the standard as of January&#160;1, 2021 and has evaluated the effects of this standard and determined that the adoption did not have a material impact on the Company&#x2019;s consolidated financial statements.&lt;/p&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>

The fair value of the impaired assets was $3.3 million at June 30, 2021. At June 30, 2021, the fair value of the assets related to construction-in-progress were primarily determined utilizing the cost approach, which determines the current replacement cost of the asset being appraised and then deducts for the loss in value caused by contractual restrictions on the asset, physical deterioration, functional obsolescence, and economic obsolescence the amount required to replace the asset as if new and adjusts to reflect usage. The fair value measurement is considered Level 3 measurements within the valuation hierarchy.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"&gt;&lt;span style="margin-bottom:12pt;visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;</us-gaap:FairValueDisclosuresTextBlock>

style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"&gt;As of June&#160;30,&#160;2021, construction-in-progress primarily includes costs related to the procurement of long-lead equipment and build out of the suite associated with the Company&#x2019;s manufacturing collaboration with Lonza Houston,&#160;Inc. (&#x201c;Lonza&#x201d;) for the manufacture of AdCOVID or other adenovirus-based vaccines. Under the agreement, the Company has committed approximately $23.0 million to Lonza to procure long-lead equipment and construct a dedicated manufacturing suite for clinical and commercial production of adenovirus-based vaccines. This work is expected to be completed by the end of 2021. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"&gt;&lt;span style="margin-bottom:12pt;visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"&gt;In June 2021, the Company announced the discontinuation of further development of AdCOVID following the Company&#x2019;s review of findings from the Phase 1 clinical trial. Construction continues at Lonza, and the Company is currently assessing its strategic options with respect to the suite. The Company&#x2019;s current expectation is that, more likely than not, the suite will be disposed of significantly before the end of its previously estimated useful life. As of June 30, 2021, the Company recorded $8.1 million of impairment loss on construction-in-progress in the accompanying unaudited consolidated statements of operations and comprehensive loss, with $3.3 million remaining capitalized in the unaudited consolidated balance sheet, as it represents expected recoveries available to the Company under the construction contract.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:0pt;margin:0pt;"&gt;&lt;span style="margin-bottom:12pt;visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"&gt;Depreciation expense related to property and equipment was approximately $68,450 and $60,664 for the three months ended June&#160;30,&#160;2021 and 2020, respectively, and $136,108 and $120,169 for the six months ended June&#160;30,&#160;2021 and 2020, respectively.&lt;/p&gt;</us-gaap:PropertyPlantAndEquipmentDisclosureTextBlock>

Such stock-based payments are subject to a lock-up whereby 50% of the shares are released at 3&#160;months and 50% are released at 6&#160;months. The future contingent payments related to the Sales Milestones are predominately cash-based payments accounted for under FASB Accounting Standards Codification Topic 450, &lt;i style="font-style:italic;"&gt;Contingencies&lt;/i&gt;. Accordingly, the Company will recognize the Sales Milestones when the contingency is resolved and the amount is paid or payable.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"&gt;The Company estimates the future contingent consideration for the Regulatory Milestones based upon a Monte Carlo simulation valuation model that is risk adjusted based on the probability of achieving the milestones and a discount for lack of marketability. The Company remeasures the fair value of the contingent consideration at each reporting period. During the fourth quarter of 2020, the Company achieved the IND Milestone and paid the obligation in shares according to the calculation above. Below is a summary of the contingent consideration activity:&lt;/p&gt;&lt;p style="font-family:'Times New

The Pre-Funded Warrants are exercisable at any time, provided that each Pre-Funded Warrant holder will be prohibited from exercising such Pre-Funded Warrants into shares of the Company&#x2019;s common stock if, as a result of such exercise, the holder, together with its affiliates, would own more than 4.99% of the total number of shares of the Company&#x2019;s common stock then issued and outstanding, which&#160;percentage may change at the &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;holders&#x2019; election to any other number less than or equal to 19.99% upon 61 days&#x2019; notice to the Company. The gross proceeds of this offering were approximately $132.2 million, which includes the exercise in full of the underwriters&#x2019; option to purchase an additional 750,000 shares of common stock, before deducting underwriting discounts and commissions and offering expenses during the third quarter of 2020.

The Pre-Funded Warrants are indexed to the Company&#x2019;s common stock and meet all other conditions for equity classification under ASC 480 and ASC 815. Accordingly, the Pre-Funded Warrants are classified as equity and are accounted for as a component of additional paid-in capital at the time of issuance. As of June&#160;30,&#160;2021, no Pre-Funded Warrants were exercised.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;At-the-Market Offerings&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;"&gt;On February&#160;25, 2021, the Company entered into an Equity Distribution Agreement (the &#x201c;2021 Agreement&#x201d;) with Piper Sandler&#160;&amp;amp; Co., Evercore Group L.L.C., and B.

As of June&#160;30,&#160;2021, the Company recorded approximately $0.1 million of offering costs which offset the proceeds received from the shares sold through June&#160;30,&#160;2021 and recognized approximately $0.1 million of deferred offering costs which will offset future proceeds received under the 2021 Agreement.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;"&gt;&lt;span style="font-size:11pt;"&gt;O&lt;/span&gt;n March&#160;27, 2020, the Company entered into an Equity Distribution Agreement (the &#x201c;2020 Agreement&#x201d;) with JMP Securities LLC, serving as placement agent (the &#x201c;Placement Agent&#x201d;) with respect to an at-the-market offerings program under which the Company may offer and sell, from time to time at its sole discretion, shares of its common stock, par value $0.0001 per share (the &#x201c;Common Stock&#x201d;), having an aggregate offering price of up to $50.0 million (the &#x201c;Shares&#x201d;) through the Placement Agent (the &#x201c;2020 Offering&#x201d;). Any Shares offered and sold in the 2020 Offering were issued pursuant to the Company&#x2019;s Registration Statement on Form&#160;S-3 filed with the SEC on April&#160;4, 2019, which was declared effective on April&#160;12, 2019, the prospectus supplement relating to the 2020 Offering filed with the SEC on March&#160;27, 2020 and any applicable additional prospectus supplements related to the 2020 Offering that form a part of the Registration Statement. The aggregate market value of Shares eligible for sale in the 2020 Offering and under the 2020 Agreement were subject to the limitations of General Instruction I.B.6 of Form&#160;S-3, to the extent required under such instruction. The Company offered Shares having an aggregate offering price of $18.9 million pursuant to the prospectus supplement filed with the SEC on March&#160;27, 2020. On June&#160;1, 2020, the Company filed an amendment to the 2020 Agreement which amended the prospectus supplement dated March&#160;27, 2020 to increase the aggregate offering price to $50.0 million. As of June&#160;30,&#160;2020, the Company sold 2,965,144 shares of Common Stock under the amended 2020 Agreement resulting in $22.8 million in net proceeds. As of June&#160;30,&#160;2021, the 2020 Agreement was fully utilized and no Shares were sold under the 2020 Agreement during the three and six months ended June&#160;30,&#160;2021.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;Exchange Agreement&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"&gt;On February&#160;25, 2021, the Company entered into an exchange agreement (the &#x201c;Exchange Agreement&#x201d;) with an Investor and its affiliates (the &#x201c;Exchanging Stockholders&#x201d;), pursuant to which the Company exchanged an aggregate of 1,000,000 shares of the Company&#x2019;s common stock, par value $0.0001 per share, owned by the Exchanging Stockholders &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;"&gt;for pre-funded warrants (the &#x201c;Exchange Warrants&#x201d;) to purchase an aggregate of 1,000,000 shares of common stock (subject to adjustment in the event of any stock dividends and splits, reverse stock split, recapitalization, reorganization or similar transaction, as described in the Exchange Warrants), with an exercise price of $0.0001 per share. The Exchange Warrants do not expire and are exercisable at any time except that the Exchange Warrants cannot be exercised by the Exchanging Stockholders if, after giving effect thereto, the Exchanging Stockholders would beneficially own more than 9.99% of the Company&#x2019;s common stock, subject to certain exceptions. In accordance with FASB Accounting Standards Codification Topic 505, &lt;i style="font-style:italic;"&gt;Equity&lt;/i&gt;, the Company recorded the retirement of the common stock exchanged as a reduction of common shares outstanding and a corresponding debit to additional paid-in-capital and accumulated deficit at the fair value of the Exchange Warrants on the issuance date. The Exchange Warrants were classified as equity in accordance with ASC 480 and the fair value of the Exchange Warrants was recorded as a credit to additional paid-in-capital and is not subject to remeasurement. The Company determined that the fair value of the Exchange Warrants is substantially similar to the fair value of the retired shares on the issuance date due to the negligible exercise price for the Exchange Warrants. As of June&#160;30,&#160;2021, none of the Exchange Warrants have been exercised.&lt;/p&gt;</alt:CommonStockTextBlock>

The competitive award was granted by USAMRDC in collaboration with the Medical Technology Enterprise Consortium (&#x201c;MTEC&#x201d;), a 501(c)(3)&#160;biomedical technology consortium working in partnership with the Department of Defense (&#x201c;DoD&#x201d;). Under the contract, MTEC will pay the Company a firm fixed fee based upon the achievement of certain milestones for conduct and completion of a Phase 1/2 study and research and development work on the replication-deficient adenovirus 5 (&#x201c;RD-Ad5&#x201d;) vector vaccine platform. For the six months ended June&#160;30,&#160;2021, the Company has recognized approximately $0.5 million of grant revenue under the contract. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"&gt;In July&#160;2016, the Company signed a five-year contract with BARDA. The contract, as amended, has a total value of up to $133.7 million and is used to fund clinical development of NasoShield. Under the contract, BARDA pays the Company a fixed fee and reimburses certain costs for the research and development of an Ad5-vectored, protective antigen-based intranasal anthrax vaccine through cGMP manufacture and conduct of a Phase 1 clinical trial dose ranging assessment of safety and immunogenicity. The contract consists of an initial base performance period providing approximately $27.8 million in funding for the period July&#160;2016 through September&#160;2021. BARDA has seven options to extend the contract to fund certain continued development and manufacturing activities for the anthrax vaccine, including Phase 2 clinical studies. Each option, if exercised by BARDA, would provide additional funding ranging from approximately $1.1 million to $34.4 million for a three-year period beginning in 2021. For the three and six months ended June&#160;30,&#160;2021, the Company has recognized approximately $0.1 million and $0.3 million, respectively, of grant revenue under the current BARDA contract. For the three and six months ended June&#160;30,&#160;2020, the Company recognized approximately $0.5 million and $2.1 million, respectively, of grant revenue under the current BARDA contract.&lt;/p&gt;</alt:USGovernmentContractsAndGrantsTextBlock>

The Company&#8217;s pipeline includes next generation peptide therapeutics for obesity, NASH (ALT-801) and chronic hepatitis B (HepTcell); proprietary intranasal vaccines; and an intranasal immune modulating therapeutic for the coronavirus disease (&#8220;COVID 19&#8221;) (T-COVID). Since its inception, the Company has devoted substantially all of its efforts to business planning, research and development, recruiting management and technical staff, and raising capital, and has financed its operations through the issuance of common and preferred stock, long-term debt, and proceeds from research grants and government contracts. The Company has not generated any revenues from the sale of any products to date, and there is no assurance of any future revenues from product sales.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">On June 29, 2021, the Company announced the discontinuation of the development program for the COVID-19 vaccine candidate, AdCOVID following the Company&#8217;s review of findings from the Phase 1 clinical trial, and in view of the highly competitive COVID-19 landscape. The Company is currently evaluating options for the future development of T-COVID as a result of enrollment challenges due to the effective rollout in the United States of authorized COVID-19 vaccines and decreasing incidence of the disease.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;">Basis of Presentation</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The accompanying unaudited consolidated financial statements are prepared pursuant to the rules&#160;and regulations of the U.S. Securities and Exchange Commission (&#8220;SEC&#8221;) regarding interim financial reporting. Accordingly, they do not include all of the information and disclosures required by accounting principles generally accepted in the United States (&#8220;U.S. GAAP&#8221;) for complete consolidated financial statements and should be read in conjunction with the audited consolidated financial statements for the&#160;year ended December&#160;31, 2020 included in the Annual Report on Form&#160;10-K which was filed with the SEC on February&#160;25, 2021. In the opinion of management, the Company has prepared the accompanying unaudited consolidated financial statements on the same basis as the audited consolidated financial statements, and these consolidated financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results of the interim periods presented. The operating results for the interim periods presented are not necessarily indicative of the results expected for the full&#160;year 2021 or any future&#160;years or periods.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The accompanying unaudited consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">The accompanying unaudited consolidated financial statements have been prepared on the basis of continuity of operations, realization of assets, and the satisfaction of liabilities in the ordinary course of business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded assets and liabilities that might be necessary should we be unable to continue as a going concern.</p><span></span>

Summary of Significant Accounting Policies</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">During the six months ended June&#160;30,&#160;2021, there have been no significant changes to the Company&#8217;s summary of significant accounting policies contained in the Company&#8217;s Annual Report on Form&#160;10-K for the&#160;year ended December&#160;31, 2020 as filed with the SEC, except for the recently adopted accounting standard for income taxes.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;">Use of Estimates</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The preparation of these financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The extent to which the COVID-19 pandemic may directly or indirectly impact the Company&#8217;s business, financial condition, and results of operations is highly uncertain and subject to change. The Company considered the potential impact of the COVID-19 pandemic on the Company&#8217;s estimates and assumptions and determined that there was not a material impact to the Company&#8217;s unaudited consolidated financial statements as of and for the three and six months ended June&#160;30,&#160;2021. However, actual results could differ from those estimates and there may be changes to the Company&#8217;s estimates in future periods.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;">Recently Issued Accounting Pronouncements&#160;- Adopted</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">In December&#160;2019, the Financial Accounting Standards Board (&#8220;FASB&#8221;) issued Accounting Standards Update (&#8220;ASU&#8221;) No.&#160;2019-12, <i style="font-style:italic;">Income Taxes</i> (Topic 740), <i style="font-style:italic;">Simplifying the Accounting for Income Taxes</i> (&#8220;ASU No.&#160;2019-12&#8221;). ASU 2019-12 amends the approaches and methodologies in accounting for income taxes during interim periods and makes changes to certain income tax classifications. The new standard allows exceptions to the use of the incremental approach for intra-period tax allocation, when there is a loss from continuing operations and income or a gain from other items, and to the general methodology for calculating income taxes in an interim period, when a&#160;year-to-date loss exceeds the anticipated loss for the&#160;year. The standard also requires franchise or similar taxes partially based on income to be reported as income tax and the effects of enacted changes in tax laws or rates to be included in the annual effective tax rate computation from the date of enactment. Lastly, in any future acquisition, the Company would be required to evaluate when the step-up in the tax basis of goodwill is part of the business combination and when it should be considered a separate transaction. The Company adopted the standard as of January&#160;1, 2021 and has evaluated the effects of this standard and determined that the adoption did not have a material impact on the Company&#8217;s consolidated financial statements.</p><span></span>

At June 30, 2021, the fair value of the assets related to construction-in-progress were primarily determined utilizing the cost approach, which determines the current replacement cost of the asset being appraised and then deducts for the loss in value caused by contractual restrictions on the asset, physical deterioration, functional obsolescence, and economic obsolescence the amount required to replace the asset as if new and adjusts to reflect usage. The fair value measurement is considered Level 3 measurements within the valuation hierarchy.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><span></span>

The Company&#8217;s current expectation is that, more likely than not, the suite will be disposed of significantly before the end of its previously estimated useful life. As of June 30, 2021, the Company recorded $8.1 million of impairment loss on construction-in-progress in the accompanying unaudited consolidated statements of operations and comprehensive loss, with $3.3 million remaining capitalized in the unaudited consolidated balance sheet, as it represents expected recoveries available to the Company under the construction contract.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:0pt;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">Depreciation expense related to property and equipment was approximately $68,450 and $60,664 for the three months ended June&#160;30,&#160;2021 and 2020, respectively, and $136,108 and $120,169 for the six months ended June&#160;30,&#160;2021 and 2020, respectively.</p><span></span>

(&#8220;Spitfire&#8221;).

Such stock-based payments are subject to a lock-up whereby 50% of the shares are released at 3&#160;months and 50% are released at 6&#160;months. The future contingent payments related to the Sales Milestones are predominately cash-based payments accounted for under FASB Accounting Standards Codification Topic 450, <i style="font-style:italic;">Contingencies</i>.

The Company remeasures the fair value of the contingent consideration at each reporting period.

The Pre-Funded Warrants are exercisable at any time, provided that each Pre-Funded Warrant holder will be prohibited from exercising such Pre-Funded Warrants into shares of the Company&#8217;s common stock if, as a result of such exercise, the holder, together with its affiliates, would own more than 4.99% of the total number of shares of the Company&#8217;s common stock then issued and outstanding, which&#160;percentage may change at the </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">holders&#8217; election to any other number less than or equal to 19.99% upon 61 days&#8217; notice to the Company.

The Pre-Funded Warrants are indexed to the Company&#8217;s common stock and meet all other conditions for equity classification under ASC 480 and ASC 815. Accordingly, the Pre-Funded Warrants are classified as equity and are accounted for as a component of additional paid-in capital at the time of issuance.

Any Shares offered and sold in the 2020 Offering were issued pursuant to the Company&#8217;s Registration Statement on Form&#160;S-3 filed with the SEC on April&#160;4, 2019, which was declared effective on April&#160;12, 2019, the prospectus supplement relating to the 2020 Offering filed with the SEC on March&#160;27, 2020 and any applicable additional prospectus supplements related to the 2020 Offering that form a part of the Registration Statement. The aggregate market value of Shares eligible for sale in the 2020 Offering and under the 2020 Agreement were subject to the limitations of General Instruction I.B.6 of Form&#160;S-3, to the extent required under such instruction. The Company offered Shares having an aggregate offering price of $18.9 million pursuant to the prospectus supplement filed with the SEC on March&#160;27, 2020. On June&#160;1, 2020, the Company filed an amendment to the 2020 Agreement which amended the prospectus supplement dated March&#160;27, 2020 to increase the aggregate offering price to $50.0 million. As of June&#160;30,&#160;2020, the Company sold 2,965,144 shares of Common Stock under the amended 2020 Agreement resulting in $22.8 million in net proceeds. As of June&#160;30,&#160;2021, the 2020 Agreement was fully utilized and no Shares were sold under the 2020 Agreement during the three and six months ended June&#160;30,&#160;2021.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;">Exchange Agreement</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">On February&#160;25, 2021, the Company entered into an exchange agreement (the &#8220;Exchange Agreement&#8221;) with an Investor and its affiliates (the &#8220;Exchanging Stockholders&#8221;), pursuant to which the Company exchanged an aggregate of 1,000,000 shares of the Company&#8217;s common stock, par value $0.0001 per share, owned by the Exchanging Stockholders </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">for pre-funded warrants (the &#8220;Exchange Warrants&#8221;) to purchase an aggregate of 1,000,000 shares of common stock (subject to adjustment in the event of any stock dividends and splits, reverse stock split, recapitalization, reorganization or similar transaction, as described in the Exchange Warrants), with an exercise price of $0.0001 per share. The Exchange Warrants do not expire and are exercisable at any time except that the Exchange Warrants cannot be exercised by the Exchanging Stockholders if, after giving effect thereto, the Exchanging Stockholders would beneficially own more than 9.99% of the Company&#8217;s common stock, subject to certain exceptions. In accordance with FASB Accounting Standards Codification Topic 505, <i style="font-style:italic;">Equity</i>, the Company recorded the retirement of the common stock exchanged as a reduction of common shares outstanding and a corresponding debit to additional paid-in-capital and accumulated deficit at the fair value of the Exchange Warrants on the issuance date. The Exchange Warrants were classified as equity in accordance with ASC 480 and the fair value of the Exchange Warrants was recorded as a credit to additional paid-in-capital and is not subject to remeasurement. The Company determined that the fair value of the Exchange Warrants is substantially similar to the fair value of the retired shares on the issuance date due to the negligible exercise price for the Exchange Warrants. As of June&#160;30,&#160;2021, none of the Exchange Warrants have been exercised.</p><span></span>

U.S. Government Contracts and Grants</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In June&#160;2020, the Company was awarded $4.7 million from the U.S. Army Medical Research&#160;&amp; Development Command (&#8220;USAMRDC&#8221;) to fund our Phase 1/2 clinical trial of T-COVID. The competitive award was granted by USAMRDC in collaboration with the Medical Technology Enterprise Consortium (&#8220;MTEC&#8221;), a 501(c)(3)&#160;biomedical technology consortium working in partnership with the Department of Defense (&#8220;DoD&#8221;). Under the contract, MTEC will pay the Company a firm fixed fee based upon the achievement of certain milestones for conduct and completion of a Phase 1/2 study and research and development work on the replication-deficient adenovirus 5 (&#8220;RD-Ad5&#8221;) vector vaccine platform. For the six months ended June&#160;30,&#160;2021, the Company has recognized approximately $0.5 million of grant revenue under the contract. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">In July&#160;2016, the Company signed a five-year contract with BARDA. The contract, as amended, has a total value of up to $133.7 million and is used to fund clinical development of NasoShield. Under the contract, BARDA pays the Company a fixed fee and reimburses certain costs for the research and development of an Ad5-vectored, protective antigen-based intranasal anthrax vaccine through cGMP manufacture and conduct of a Phase 1 clinical trial dose ranging assessment of safety and immunogenicity. The contract consists of an initial base performance period providing approximately $27.8 million in funding for the period July&#160;2016 through September&#160;2021. BARDA has seven options to extend the contract to fund certain continued development and manufacturing activities for the anthrax vaccine, including Phase 2 clinical studies. Each option, if exercised by BARDA, would provide additional funding ranging from approximately $1.1 million to $34.4 million for a three-year period beginning in 2021. For the three and six months ended June&#160;30,&#160;2021, the Company has recognized approximately $0.1 million and $0.3 million, respectively, of grant revenue under the current BARDA contract. For the three and six months ended June&#160;30,&#160;2020, the Company recognized approximately $0.5 million and $2.1 million, respectively, of grant revenue under the current BARDA contract.</p><span></span>

Net Loss Per Share</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Because the Company has reported a net loss attributable to common stockholders for all periods presented, basic and diluted net loss per share attributable to common stockholders are the same for all periods presented.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted average numbers of shares of common stock outstanding for the period. Basic shares outstanding includes the weighted average effect of the Company&#8217;s outstanding pre-funded warrants, the exercise of which requires little or no consideration for the delivery of shares of common stock.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Diluted net loss per share is calculated by adjusting weighted average shares outstanding for the dilutive effect of common stock equivalents outstanding for the period. As such, all unvested restricted stock, common stock warrants, and stock options have been excluded from the computation of diluted weighted average shares outstanding because such securities would have an anti-dilutive impact for all periods presented.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt

weighted-average shares outstanding, as they are anti-dilutive, are as follows:</p><table

The extent to which the COVID-19 pandemic may directly or indirectly impact the Company&#8217;s business, financial condition, and results of operations is highly uncertain and subject to change. The Company considered the potential impact of the COVID-19 pandemic on the Company&#8217;s estimates and assumptions and determined that there was not a material impact to the Company&#8217;s unaudited consolidated financial statements as of and for the three and six months ended June&#160;30,&#160;2021. However, actual results could differ from those estimates and there may be changes to the Company&#8217;s estimates in future periods.</p><span></span>

ASU 2019-12 amends the approaches and methodologies in accounting for income taxes during interim periods and makes changes to certain income tax classifications. The new standard allows exceptions to the use of the incremental approach for intra-period tax allocation, when there is a loss from continuing operations and income or a gain from other items, and to the general methodology for calculating income taxes in an interim period, when a&#160;year-to-date loss exceeds the anticipated loss for the&#160;year. The standard also requires franchise or similar taxes partially based on income to be reported as income tax and the effects of enacted changes in tax laws or rates to be included in the annual effective tax rate computation from the date of enactment. Lastly, in any future acquisition, the Company would be required to evaluate when the step-up in the tax basis of goodwill is part of the business combination and when it should be considered a separate transaction. The Company adopted the standard as of January&#160;1, 2021 and has evaluated the effects of this standard and determined that the adoption did not have a material impact on the Company&#8217;s consolidated financial statements.</p><span></span>

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