Soligenix, Inc. (the “Company”) is a late-stage biopharmaceutical company focused on developing and commercializing products to treat rare diseases where there is an unmet medical need. The Company maintains two active business segments: Specialized BioTherapeutics (formerly “BioTherapeutics”) and ~~Vaccines/BioDefense.~~Public Health Solutions (formerly “Vaccines/BioDefense”).

The Company’s Specialized BioTherapeutics business segment is developing a novel photodynamic therapy (SGX301) utilizing topical synthetic hypericin activated with safe visible ~~florescent~~fluorescent light for the treatment of cutaneous T-cell lymphoma (“CTCL”), its first-in-class innate defense regulator ~~(“IDR”)~~ technology, dusquetide (SGX942) for the treatment of oral mucositis in head and neck cancer, and proprietary formulations of oral beclomethasone 17,21-dipropionate (“BDP”) for the prevention/treatment of gastrointestinal ~~(“GI”)~~ disorders characterized by severe inflammation, including pediatric Crohn’s disease (SGX203) and acute radiation enteritis (SGX201).

The Company’s ~~Vaccines/BioDefense~~Public Health Solutions business segment includes active development programs for RiVax^®, its ricin toxin vaccine candidate ~~OrbeShield~~^®~~, a GI acute radiation syndrome (“GI ARS”) therapeutic candidate~~ and SGX943, a therapeutic candidate for antibiotic resistant and emerging infectious ~~disease.~~disease, and vaccine programs targeting both filoviruses (such as Marburg and Ebola) and coronaviruses. The development of the vaccine ~~program~~programs is currently supported by the heat stabilization technology, known as ThermoVax^®~~, under existing~~. To date, this business segment has been supported with government grant and ~~on-going government~~ contract ~~funding. With the government contract~~funding from the National Institute of Allergy and Infectious Diseases (“NIAID”), the ~~Company will attempt to advance the development of RiVax~~^® ~~to protect against exposure to ricin toxin. The Company has advanced the development of OrbeShield~~^® ~~for the treatment of GI ARS with funds received under its awarded government contracts with the~~ Biomedical Advanced Research and Development Authority ~~(“BARDA”)~~ and ~~NIAID. The Company will continue to pursue additional government funding support.~~the Defense Threat Reduction Agency (“DTRA”).

The Company generates revenues under government grants primarily from the National Institutes of Health (“NIH”) and government contracts from ~~BARDA and~~ NIAID. The Company is currently developing RiVax^®under a ~~NIH~~NIAID contract of up to ~~$24.7~~$21.2 million over six years, and ~~SGX301 and~~a one-year NIH grant of $150,000 in support of its SGX942 ~~under two separate NIH grants~~pediatric program. In addition, the Company has a subcontract of approximately ~~$1.5 million each~~$700,000 from a NIAID grant over ~~two years. The NIAID contract~~five years for ~~the development~~its thermostabilization technology, and a DTRA subcontract of ~~OrbeShield~~^®~~was completed during the first quarter of 2017 along with the BARDA contract base period, with BARDA electing not to extend the current contract beyond the base period.~~approximately $600,000 over three years for SGX943. The Company will continue to apply for additional government funding.

The Company is subject to risks common to companies in the biotechnology industry including, but not limited to, development of new technological innovations, dependence on key personnel, protections of proprietary technology, compliance with the United States (“U.S.”) Food and Drug Administration (the ~~U.S.~~ “FDA”) regulations, and other regulatory authorities, litigation, and product liability. Results for the three and ~~nine~~six months ended ~~September~~June 30, ~~2017~~2020 are not necessarily indicative of results that may be expected for the full year.

In accordance with Accounting Standards Codification 205-40, Going Concern, the Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date the consolidated financial statements are issued. As of ~~September~~June 30, ~~2017,~~2020, the Company had an accumulated deficit of ~~$155,131,091.~~$185,883,709. During the ~~nine~~six months ended ~~September~~June 30, ~~2017,~~2020, the Company incurred a net loss of ~~$5,008,129~~$10,358,097 and used ~~$4,192,304~~$4,338,530 of cash in ~~operations.~~operating activities. The Company expects to continue to generate losses in the foreseeable future. The Company’s liquidity needs will be largely determined by the budgeted operational expenditures incurred in regards to the progression of its product candidates. The Company’s plans to meet its liquidity needs primarily include its ability to control the timing and spending on its research and development programs and raising additional funds through potential ~~partnerships~~partnership and/or financings. Based on the Company’s approved operating budget, ~~management believes that it will have sufficient capital to meet the anticipated cash needs for working capital and capital expenditures through at least December 31, 2018. Based on the Company’s~~ current rate of cash outflows, cash on hand, proceeds from government contract and grant programs, and proceeds available from the ~~equity line with Lincoln Park Capital Fund, LLC (“Lincoln Park”), proceeds remaining from the sale of the Company’s common stock pursuant to the At-the-Market (“ATM”)~~At Market Issuance Sales Agreement (“FBR Sales Agreement”) with B. Riley FBR ~~Capital Markets & Co.~~Inc. (“FBR”) ~~and proceeds from the State of New Jersey Technology Business Tax Certificate Transfer Program,~~, management believes that its current cash will be sufficient to meet the anticipated cash needs for working capital and capital expenditures ~~through~~for at least ~~December 31, 2018.~~the next 12 months from issuance of the financial statements.

As of ~~September~~June 30, ~~2017,~~2020, the Company had cash and cash equivalents of ~~$4,999,153~~$11,168,305 as compared to ~~$8,772,567~~$5,420,708 as of December 31, ~~2016,~~2019, representing ~~a decrease~~an increase of ~~$3,773,414~~$5,747,597 or ~~43%~~106%. As of ~~September~~June 30, ~~2017,~~2020, the Company had working capital of ~~$3,047,007~~$5,992,411 as compared to working capital of ~~$7,243,918~~$1,181,249 as of December 31, ~~2016,~~2019, representing ~~a decrease~~an increase of ~~$4,196,911~~$4,811,162 or ~~58%~~407%. The ~~decrease is~~increase in cash and working capital was primarily related to ~~expenditures to support~~ the ~~pivotal Phase 3 clinical trial of SGX301 for the treatment of CTCL and expenditures incurred in preparation and initiation~~management of the ~~Phase 3 clinical trial~~Company’s expenses, and proceeds received from the utilization of ~~SGX942 for~~ the ~~treatment of oral mucositis in head~~FBR Sales Agreement and ~~neck cancer.~~warrant exercises during the six months ended June 30, 2020.

The Company’s plans with respect to its liquidity management include, but are not limited to, the following:

On October 7, 2016, the Company completed a reverse stock split of its issued and outstanding shares of common stock at a ratio of one-for-ten, whereby every ten shares of its common stock was exchanged for one share of its common stock. The Company’s common stock began trading on the OTCQB on a reverse split basis at the market opening on October 7, 2016. All share and per share data have been restated to reflect this reverse stock split.

The consolidated financial statements include Soligenix, Inc., and its wholly and majority owned subsidiaries. All significant intercompany accounts and transactions have been eliminated as a result of consolidation.

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated on a regular basis by the chief operating decision maker, or decision making group, in deciding how to allocate resources to an individual segment and in assessing the performance of the segment. The Company divides its operations into two operating segments: Specialized BioTherapeutics and ~~Vaccines/BioDefense.~~Public Health Solutions.

The Company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents.

Contracts and grants receivable consist of amounts due from various grants from the NIH and contracts from ~~BARDA and~~ NIAID, an institute of ~~the NIH, and from various grants from the~~ NIH, for costs incurred prior to the period end under reimbursement contracts. The amounts were billed to the respective governmental agencies in the month subsequent to period end and collected shortly thereafter. Accordingly, no allowance for doubtful amounts has been established. If amounts become uncollectible, they are charged to operations.

One of the most significant estimates or judgments that the Company makes is whether to capitalize or expense patent and license costs. The Company makes this judgment based on whether the technology has alternative future uses, as defined in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 730,Research and Development. Based on this consideration, the Company capitalizes payments made to legal firms that are engaged in filing and protecting rights to intellectual property and rights for its current products in both the domestic and international markets. The Company believes that patent rights are one of its most valuable assets. Patents and patent applications are a key component of intellectual property, especially in the early stage of product development, as their purchase and maintenance gives the Company access to key product development rights from Soligenix’s academic and industry partners. These rights can also be sold or sub-licensed as part of its strategy to partner its products at each stage of development as the intangible assets have alternative future use. The legal costs incurred for these patents consist of work associated with filing new patents designed to protect, preserve and maintain the Company’s rights, and perhaps extend the lives of the patents. The Company capitalizes such costs and amortizes intangibles on a straight-line basis over their expected useful life – generally a period of 11 to 16 years.

The Company did not capitalize any patent related costs during the ~~nine~~three or six months ended June 30, 2020 and 2019.

In February 2019, Altamont Pharmaceutical Holdings, LLC, a company which since January 1, 2019 beneficially owned 5% or more of the shares of the Company’s outstanding common stock but which beneficially owned less than 5% of the Company’s outstanding common stock as of June 30, 2020, signed a service agreement with a third-party vendor to re-develop the Company’s website. Upon completion of the project at the end of June 2019, the Company capitalized the related website development costs of $46,500 in accordance with FASB Codification ASC 350-50 “Accounting for Web Site Development Costs”, which was reported in other assets in the accompanying consolidated balance sheets. Beginning with the three months ended September 30, ~~2017~~2019, the Company started amortizing the website development costs on a straight-line basis over three years, the estimated useful life of the website. The Company will also review its capitalized website development costs periodically for impairment. Website amortization expense for the three months ended June 30, 2020 was $3,875 and ~~2016.~~for the six months ended June 30, 2020 was $7,752 and accumulated amortization was $15,502 as of June 30, 2020.

Office furniture and equipment, website development costs and intangible assets with finite lives are evaluated and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. The Company recognizes impairment of long-lived assets in the event the net book value of such assets exceeds the estimated future undiscounted cash flows attributable to such assets. If the sum of the expected undiscounted cash flows is less than the carrying value of the related asset or group of assets, a loss is recognized for the difference between the fair value and the carrying value of the related asset or group of assets. Such analyses necessarily involve significant judgment.

The Company did not record any impairment of long-lived assets for the ~~nine~~three or six months ended ~~September~~June 30, ~~2017 and 2016.~~2020 or 2019.

FASB ASC 820 —Fair Value Measurements and Disclosures,defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. FASB ASC 820 requires disclosures about the fair value of all financial instruments, whether or not recognized, for financial statement purposes. Disclosures about the fair value of financial instruments are based on pertinent information available to the Company on ~~September~~June 30, ~~2017.~~2020. Accordingly, the estimates presented in these financial statements are not necessarily indicative of the amounts that could be realized on disposition of the financial instruments.

FASB ASC 820 specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect market assumptions. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement).

The carrying amounts reported in the consolidated balance sheet for cash and cash equivalents, contracts and grants receivable, tax receivable, research and development incentives receivable, accounts payable, accrued expenses, and accrued compensation approximate their fair value based on the short-term ~~maturity~~nature of these instruments.

The Company’s revenues are primarily generated from government contracts and grants. The revenue from government contracts and grants is based upon subcontractor costs and internal costs incurred that are specifically covered by the contracts and grants, plus a facilities and administrative rate that provides funding for overhead expenses and management fees. These revenues are recognized when expenses have been incurred by subcontractors or when the Company incurs reimbursable internal expenses that are related to the government contracts and grants.

Research and development costs are charged to expense when incurred in accordance with FASB ASC 730,Research and Development. Research and development includes costs such as clinical trial expenses, contracted research and license agreement fees with no alternative future use, supplies and materials, salaries, share-based compensation, employee benefits, equipment depreciation and allocation of various corporate costs. Purchased in-process research and development expense represents the value assigned or paid for acquired research and development for which there is no alternative future use as of the date of acquisition.

~~The Company considered FASB ASC 815,~~~~Evaluating Whether an Instrument is Considered Indexed to an Entity’s Own Stock~~, which provides guidance for determining whether an equity-linked financial instrument (or embedded feature) issued by an entity is indexed to the entity’s stock and, therefore, qualifying for the first part of the scope exception in paragraph 815-10-15. The Company evaluated the provisions and determined that the warrants issued in connection with the Company’s June 2013 registered public offering contains provisions that protect holders from a decline in the issue price of the Company’s common stock (or “down-round” provisions) and contain net settlement provisions. Consequently, these warrants were recognized as liabilities at their fair value on the date of grant and remeasured at fair value on each reporting date.

During the year ended December 31, 2016, the Company entered into amendments with the holders of those warrants, and as a result the warrants were then reclassified to equity as the amended terms of the warrants qualified them to be accounted for as equity instruments.

Stock options are issued with an exercise price equal to the market price on the date of grant. Stock options issued to directors upon re-election vest quarterly for a period of one year (new director issuances are fully vested upon issuance). Stock options issued to employees generally vest 25% on the grant date, then 25% each subsequent year for a period of three years. These options have a ten year life for as long as the individuals remain employees or directors. In general, when an employee or director terminates their position, the options will expire within three months, unless otherwise extended by the Board.

From time to time, the Company issues restricted shares of common stock to vendors and consultants as compensation for services ~~performed. Typically these instruments vest upon issuance~~performed under the Company’s 2015 Equity Incentive Plan (the “2015 Plan”). The 2015 Plan provides for the grant of stock options, restricted stock, deferred stock and ~~therefore~~unrestricted stock to our employees and non-employees (including consultants). The shares issued under the ~~entire share-based compensation expense is recognized upon issuance to the vendors and/or consultants.~~

~~Share-based compensation expense for options, warrants and~~2015 Plan are registered on Form S-8 (SEC File No. 333-208515). However, as shares of common stock ~~granted~~are not covered by a reoffer prospectus, the certificates reflecting such shares reflect a Securities Act of 1933, as amended (the “Securities Act”) restrictive legend. Stock compensation expense for equity-classified awards to ~~non-employees has been determined in accordance with FASB ASC 505-50,~~~~Equity-Based Payments to Non-Employees~~,nonemployees is measured on the date of grant and ~~represents~~is recognized when the fair value of the consideration received, or the fair value of the equity instruments issued, whichever may be more reliably measured. For options that vest over future periods, the fair value of options granted to non-employees is amortized as the options vest. The fair value is remeasured each reporting period until performance is complete.services are performed.

~~For the nine months ended September 30, 2017 and 2016, the Company issued stock options at a weighted average exercise price of $2.55 and $7.72 per share, respectively.~~ The fair value of options issued during the ~~nine~~six months ended ~~September~~June 30, ~~2017~~2020 and ~~2016 were~~2019 was estimated using the Black-Scholes option-pricing model and the following assumptions:

In 2018, the Company changed the status of a wholly owned subsidiary in the United Kingdom (“UK”) from inactive to active and incurred expenditures in multiple currencies including the U.S. dollar, the British Pound and the Euro to fund its clinical trial operations in the UK and select countries in Europe. In accordance with FASB ASC 830 Foreign Currency Matters, the UK subsidiary expresses its U.S. dollar and Euro denominated transactions in its functional currency, the British Pound, with related transaction gains or losses included in net income. On a quarterly basis, the financial statements of the UK subsidiary are translated into U.S. dollars and consolidated into the Company’s financials, with related translation adjustments reported as a cumulative translation adjustment (“CTA”), which is a component of accumulated other comprehensive loss. During the three months ended June 30, 2020 and 2019, the Company recognized a foreign currency transaction loss of $3,583 and a gain of $1,519, respectively, in the accompanying consolidated statements of operations. During the six months ended June 30, 2020 and 2019, the Company recognized a foreign currency transaction loss of $26,818 and a foreign currency transaction gain of $6,526, respectively, in the accompanying consolidated statements of operations.

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. A valuation allowance is established when it is more likely than not that all or a portion of a deferred tax asset will not be realized. A review of all available positive and negative evidence is considered, including the Company’s current and past performance, the market environment in which the Company operates, the utilization of past tax credits, and the length of carryback and carryforward periods. Deferred tax assets and liabilities are measured utilizing tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. ~~No current or deferred~~The Company recognized an income ~~taxes have been provided through September~~tax benefit of $836,893 and $610,676 from the sale of New Jersey NOL carryforwards during the six months ended June 30, ~~2017 due to the net operating losses incurred by the Company since its inception.~~2020 and 2019, respectively.

There were no tax related interest and penalties recorded for ~~2017 and 2016.~~the six months ended June 30, 2020 or 2019. Additionally, the Company has not recorded an asset for unrecognized tax benefits or a liability for uncertain tax positions at ~~September~~June 30, ~~2017~~2020 and December 31, ~~2016.~~2019.

The Company recognizes other income from United Kingdom research and development incentives when there is reasonable assurance that the income will be received, the relevant expenditure has been incurred, and the consideration can be reliably measured. The small or medium sized enterprise (“SME”) research and development tax relief program supports companies that seek to research and develop an advance in their field and is governed through legislative law by HM Revenue & Customs as long as specific eligibility criteria are met.

Management has assessed the Company’s research and development activities and expenditures to determine which activities and expenditures are likely to be eligible under the SME research and development tax relief program described above. At each period end, management estimates the refundable tax offset available to the Company based on available information at the time. As the tax incentives may be received without regard to an entity’s actual tax liability, they are not subject to accounting for income taxes. As a result, amounts realized under the SME research and development tax relief program are recorded as a component of other income.

The following table shows the change in the United Kingdom research and development incentives receivable from December 31, 2019 to June 30, 2020:

Basic earnings per share (“EPS”) excludes dilution and is computed by dividing income (loss) available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that shared in the earnings of the entity. Since there is a significant number of options and warrants outstanding, fluctuations in the actual market price can have a variety of results for each period presented.

The following table summarizes potentially dilutive adjustments to the ~~weighted average~~ number of common shares which were excluded from the diluted calculation because their effect would be ~~anti-dilutive.~~anti-dilutive due to the losses in each period:

The weighted average exercise price of the Company’s warrants and stock options ~~and warrants~~ outstanding at ~~September~~June 30, ~~2017~~2020 were ~~$9.93~~$2.92 and ~~$4.45~~$3.20 per share, respectively, and at ~~September~~June 30, ~~2016~~2019 were ~~$18.20~~$4.97 and ~~$7.38~~$3.09 per share, respectively.

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions such as the fair value of warrants and, stock options and ~~recovery of~~ the useful life of intangibles that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those ~~estimates.~~

~~In February 2016, the FASB issued ASU No. 2016-02, “Leases” (topic 842). The FASB issued this update to increase transparency~~estimates and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The updated guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption of the update is permitted. The Company is evaluating the impact of the adoption of this update on its consolidated financial statements and related disclosures.presentation.

In March 2016, the FASB issued ASU No. 2016-09, “Improvements to Employee Share-Based Payment Accounting,” which amends ASC Topic 718, and intends to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. It is effective for annual reporting periods beginning after December 15, 2016, and interim periods within that reporting period. The Company adopted this standard effective January 1, 2017, and elected not to change its accounting policy with respect to the estimation of forfeitures. As a result, there was no material impact to the financial statements.

~~In July 2017, the FASB issued ASU No. 2017-11,~~(Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception. The new standard applies to issuers of financial instruments with down-round features. A down-round provision is a term in an equity-linked financial instrument (i.e. a freestanding warrant contract or an equity conversion feature embedded within a host debt or equity contract) that triggers a downward adjustment to the instrument’s strike price (or conversion price) if equity shares are issued at a lower price (or equity-linked financial instruments are issued at a lower strike price) than the instrument’s then-current strike price. The purpose of the feature is typically to protect the instrument’s counterparty from future issuances of equity shares at a more favorable price. The ASU amends (1) the classification of such instruments as liabilities or equity by revising the certain guidance relative to evaluating if they must be accounted for as derivative instruments and (2) the guidance on recognition and measurement of freestanding equity-classified instruments. For the Company, this ASU is effective January 1, 2019, with early adoption permitted. The Company is evaluating the impact of the adoption of this update on its consolidated financial statements and related disclosures.

The following is a summary of intangible assets which consists of licenses and patents:

Amortization expense was ~~$14,963 and $15,589~~$6,791 for each of the three months ended ~~September~~June 30, ~~2017~~2020 and ~~2016, respectively, and $45,810 and $46,424~~2019.

Based on the balance of licenses and patents at ~~September~~June 30, ~~2017,~~2020, future amortization expense through December 31, 2020 is expected to be ~~as follows:~~$6,117.

License fees and royalty payments are expensed as incurred, as the Company does not attribute any future benefits toof such payments.

The Company classifies a lease for its office space at 29 Emmons Drive, Suite B-10 in Princeton, New Jersey and a lease for a copier machine in the office as an operating lease and a financing lease, respectively, and records related right-of-use lease assets and lease liabilities accordingly. As of June 30, 2020, the Company’s consolidated balance sheet included a right-of-use lease asset of $46,089 for the office space and $9,304 for the copier machine. Lease liabilities in the Company’s consolidated balance sheet included corresponding lease liabilities of $46,555 and $10,001 respectively. During the six months ended June 30, 2020, the Company recognized lease expense of $70,595 for the operating lease, in addition to amortization expense of $3,721 and interest expense of $608 for the financing lease in the Company’s consolidated statement of operations.

~~Note 5. Notes Payable~~

On July 29, 2015, the Company entered into equity purchase agreements (the “Equity Line Purchase Agreements”) and registration rights agreements with certain accredited institutional investors. In consideration for entering into the Equity Line Purchase Agreements, the Company issued to the investors promissory notes having an aggregate principal amount of $300,000, which were recorded as stock issuance costs. The promissory notes had an issuance date present value of $282,071 and were paid on April 15, 2016. The promissory notes did not include terms for interest, therefore the interest was imputed at 9%. The discount was being accreted over the term of the promissory notes using the effective interest rate method.

Note 6. ~~Warrant Liability~~

On June 25, 2013, the Company consummated a public offering in which the Company issued shares of common stock, together with warrants to purchase shares of common stock. These warrants contained provisions that protected holders from a decline in the issue price of its common stock (or “down-round” provision) and contained net settlement provisions. As a result, the Company accounted for these warrants as liabilities instead of equity instruments. Down-round provisions reduce the exercise or conversion price of a warrant if the Company issues equity shares for a price that is lower than the exercise or conversion price of the warrants. Net settlement provisions allow the holder of the warrant to surrender shares underlying the warrant equal to the exercise price as payment of its exercise price, instead of exercising the warrant by paying cash. The Company evaluates whether warrants to acquire its common stock contain provisions that protect holders from declines in the stock price or otherwise could result in modification of the exercise price and/or the number of shares to be issued under the respective warrant agreements based on a variable that is not an input to the fair value of a “fixed for fixed” option. As a result of the Company’s December 2014 registered public unit offering, the exercise price of warrants outstanding in connection with the public offering completed in June 2013 was adjusted to $6.10 per share. As a result of the Company’s December 2015 drawings on the Equity Line Purchase Agreements, the exercise price of warrants outstanding in connection with the public offering conducted in June 2013 was adjusted to $5.10 per share. The Company recognized these warrants as liabilities at their fair value on the date of grant and remeasured them to fair value on each reporting date.

The table below provides a reconciliation of the beginning and ending balances for the liability measured at fair value using significant unobservable inputs (Level 3) for the nine months ended September 30, 2016:

However, these NOLs are subject to various limitations under Internal Revenue Code (“IRC”) Section 382.

In addition, the NOL ~~carry forwards~~carryforwards are subject to examination by the taxing authority and could be adjusted or disallowed due to such exams. Although the Company has not undergone an IRC Section 382 analysis, it is likely that the utilization of the NOLs may be substantially limited.

~~BioTherapeutics Overview~~

SGX301 – for Treating Cutaneous T-Cell Lymphoma

SGX301 is a novel, first-in-class, photodynamic therapy that utilizes safe visible light for activation. The active ingredient in SGX301 is synthetic hypericin, a photosensitizer which is topically applied to skin lesions and then activated by fluorescent light 16 to 24 hours later. Hypericin is also found in several species ofHypericum plants, although the drug used in SGX301 is chemically synthesized by a proprietary manufacturing process and not extracted from plants. Importantly, hypericin is optimally activated with visible light thereby avoiding the negative consequences of ultraviolet light. Other light therapies using UVA or UVB light can result in serious adverse effects including secondary skin cancers.

Combined with photoactivation, in clinical trials synthetic hypericin has demonstrated significant anti-proliferative effects on activated normal human lymphoid cells and inhibited growth of malignant T-cells isolated from CTCL patients. In both settings, it appears that the mode of action is an induction of cell death in a concentration as well as a light dose-dependent fashion. These effects appear to result, in part, from the generation of singlet oxygen during photoactivation of hypericin.

Hypericin is one of the most efficient known generators of singlet oxygen, the key component for phototherapy. The generation of singlet oxygen induces necrosis and apoptosis in adjacent cells. The use of topical synthetic hypericin coupled with directed visible light results in generation of singlet oxygen only at the treated site. We believe that the use of visible light (as opposed to cancer-causing ultraviolet light) is a major advance in photodynamic therapy. In a published Phase 2 clinical study in CTCL, after six weeks of twice weekly therapy, a majority of patients experienced a statistically significant (p<0.04) improvement with ~~topical hypericin treatment~~SGX301 whereas the placebo was ineffective: 58.3% compared to 8.3%, respectively.

SGX301 has received Orphan Drug designation as well as Fast Track designation from the ~~FDA.~~United States (“U.S.”) Food and Drug Administration (“FDA”). The Orphan Drug Act is intended to assist and encourage companies to develop safe and effective therapies for the treatment of rare diseases and disorders. In addition to providing a seven-year term of market exclusivity for SGX301 upon final FDA approval, Orphan Drug designation also positions us to be able to leverage a wide range of financial and regulatory benefits, including government grants for conducting clinical trials, waiver of FDA user fees for the potential submission of ~~a New Drug Application (“NDA”)~~an NDA for SGX301, and certain tax credits. In addition, Fast Track is a designation that the FDA reserves for a drug intended to treat a serious or life-threatening condition and one that demonstrates the potential to address an unmet medical need for the condition. Fast Track designation is designed to facilitate the development and expedite the review of new drugs. For instance, should events warrant, we will be eligible to submit a NDA for SGX301 on a rolling basis, permitting the FDA to review sections of the NDA prior to receiving the complete submission. Additionally, NDAs for Fast Track development programs ordinarily will be eligible for priority review. SGX301 for the treatment of CTCL also was granted Orphan Drug designation from the European Medicines Agency (“EMA”) Committee for Orphan Medical Products and Promising Innovative Medicine (“PIM”) designation from the Medicines and Healthcare Products Regulatory Agency (“MHRA”) in the United Kingdom (“UK”).

WeIn August 2018, the U.S. Patent Office granted us a patent titled “Systems and Methods for Producing Synthetic Hypericin” for the unique proprietary process manufacturing the highly purified form of synthetic hypericin, the active pharmaceutical ingredient in SGX301.

In October 2019, the U.S. Patent Office allowed the divisional patent application titled “Systems and Methods for Producing Synthetic Hypericin”. The allowed claims are directed to unique, proprietary methods to produce a novel, highly purified form of synthetic hypericin. This new divisional claim set expands on the previous issued claims in the parent U.S. patent.

In April 2020, the European patent office granted the divisional patent application titled “Formulations and Methods of Treatment of Skin Conditions” (No. 2932973). The granted claims are directed to the therapeutic use of synthetic hypericin in the treatment of CTCL. This new patent expands on our comprehensive patent estate, which includes protection on the composition of the purified synthetic hypericin, methods of synthesis and therapeutic methods of use in both CTCL and psoriasis, and is being pursued worldwide.

Based on the positive and previously published Phase 2 results, we initiated our pivotal Phase 3 clinical study of SGX301 for the treatment of CTCL during December ~~2015 and are actively enrolling patients.~~2015. This trial, referred to as the “FLASH” study (Fluorescent Light Activated Synthetic Hypericin), aims to evaluate the response to SGX301 as a skin directed therapy to treat early stage CTCL. We have completed patient enrollment with approximately 35 CTCL centers across the U.S. participating in this pivotal trial. The Phase 3 protocol is ~~expected to be~~ a highly powered, double-blind, randomized, placebo-controlled, multicenter trial ~~and will seek to enroll approximately 120 evaluable subjects.~~that enrolled 169 subjects (166 evaluable). The trial ~~will consist~~consists of three treatment cycles, each of eight weeks duration. Treatments ~~will be~~are administered twice weekly for the first six weeks and treatment response ~~will be~~is determined at the end of the eighth week. In the first treatment cycle, approximately 8066% of subjects ~~will receive~~received SGX301 and ~~40 will receive~~33% received placebo treatment of their index lesions. In the second cycle, all subjects ~~will receive~~received SGX301 treatment of their index lesions, and in the third cycle, all subjects ~~will receive~~received or are receiving SGX301 treatment of all of their lesions. The majority of subjects enrolled elected to continue into the third optional, open-label cycle of the study. We continue to work closely with the Cutaneous Lymphoma Foundation, as well as the National Organization for Rare Disorders. Subjects ~~will be~~are followed for an additional ~~nine~~six months after ~~the completion of treatment.~~their last evaluation visit. The primary efficacy endpoint ~~will be~~is assessed on the percentage of patients in each of the two treatment groups (i.e., SGX301 and placebo) achieving a partial or complete response of the treated lesions, defined as a ≥ 50% reduction in the total Composite Assessment of Index Lesion Disease Severity (“CAILS”) score for three index lesions at the Cycle 1 evaluation visit (Week 8) compared to the total CAILS score at baseline. Other secondary measures ~~will~~ assess treatment response including duration, degree of improvement, time to relapse and safety.

During September 2017, ~~we announced~~ the National Cancer Institute (“NCI”), part of the National Institutes of Health (“NIH”) awarded us a Small Business Innovation Research (“SBIR”) grant of approximately $1.5 million over two years to support the conduct of our pivotal, Phase 3, randomized, double-blind, placebo-controlled study evaluating SGX301 (synthetic hypericin) as a treatment for CTCL. This grant has been exhausted as of December 2019.

During October 2018, an Independent Data Monitoring Committee (“DMC”) completed an unblinded interim analysis with data from approximately 100 subjects, including an assessment of the Phase 3 FLASH study’s primary efficacy endpoint. The DMC provided a positive recommendation to randomize approximately 40 additional subjects into the trial to maintain the rigorous assumption of 90% statistical power for the primary efficacy endpoint. No safety concerns were reported by the DMC based on the interim analysis.

Positive primary endpoint analysis for the Phase 3 study for SGX301 was completed in March 2020. The study enrolled 169 patients (166 evaluable) randomized 2:1 to receive either SGX301 (116 patients) or placebo (50 patients) and demonstrated a statistically significant treatment response (p=0.04) in the CAILS primary endpoint assessment at 8 weeks for Cycle 1. A total of 16% of the patients receiving SGX301 achieved at least a 50% reduction in their index lesions compared to only 4% of patients in the placebo group at 8 weeks. SGX301 treatment in the first cycle was safe and well tolerated.

During April 2020, analysis of the second open-label treatment cycle (“Cycle 2”) was completed, showing that continued treatment with SGX301 twice weekly for an additional 6 weeks (12 weeks total) increased the positive response rate to 40% (p<0.0001 compared to placebo and p<0.0001 compared to 6-weeks treatment). After the subsequent additional 6-week treatment, the response rate in patients receiving a total of 12 weeks treatment increased two and a half-fold. Treatment responses were assessed at Week 8 (after 6 weeks of treatment) and at week 16 (after 12 weeks of treatment). A positive response was defined as an improvement of at least 50% in the CAILS for three index lesions evaluated in both Cycles 1 and 2. The data continues to indicate that SGX301 is safe and well tolerated.

We estimate the potential worldwide market for SGX301 is in excess of $250 million for all applications, including the treatment of CTCL. This potential market information is a forward-looking statement, and investors are urged not to place undue reliance on this statement. While we have determined this potential market size based on assumptions that we believe are reasonable, there are a number of factors that could cause our expectations to change or not be realized.

Cutaneous T-Cell Lymphoma

CTCL is a class of non-Hodgkin’s lymphoma (“NHL”), a type of cancer of the white blood cells that are an integral part of the immune system. Unlike most NHLs, which generally involve B-cell lymphocytes (involved in producing antibodies), CTCL is caused by an expansion of malignant T-cell lymphocytes (involved in cell-mediated immunity) normally programmed to migrate to the skin. These skin-trafficking malignant T-cells migrate to the skin, causing various lesions to appear that may change shape as the disease progresses, typically beginning as a rash and eventually forming plaques and tumors. Mycosis fungoides (“MF”) is the most common form of CTCL. It generally presents with skin involvement only, manifested as scaly, erythematous patches. Advanced disease with diffuse lymph node and visceral organ involvement is usually associated with a poorer response rate to standard therapies. A relatively uncommon sub-group of CTCL patients present with extensive skin involvement and circulating malignant cerebriform T-cells, referred to as Sézary syndrome. These patients have substantially graver prognoses (expected five-year survival rate of 24%), than those with ~~MF.~~MF (expected five-year survival rate of 88%).

CTCL mortality is related to stage of disease, with median survival generally ranging from about 12 years in the early stages to only 2.5 years when the disease has advanced. There is currently no FDA-approved drug for front-line treatment of early stage CTCL. Treatment of early-stage disease generally involves skin-directed therapies. One of the most common unapproved therapies used for early-stage disease is oral 5 or 8-methoxypsoralen (“Psoralen”) given with ultraviolet A (“UVA”) light, referred to as PUVA, which is approved for dermatological conditions such as disabling psoriasis not adequately responsive to other forms of therapy, idiopathic vitiligo and skin manifestations of CTCL in persons who have not been responsive to other forms of treatment. Psoralen is a mutagenic chemical that interferes with DNA causing mutations and other malignancies. Moreover, UVA is a carcinogenic light source that when combined with the Psoralen, results in serious adverse effects including secondary skin cancers; therefore, the FDA requires a Black Box warning for PUVA.

CTCL constitutes a rare group of NHLs, occurring in about 4% of the approximate 500,000 individuals living with NHL. We estimate, based upon review of historic published studies and reports and an interpolation of data on the incidence of CTCL, that it affects over 20,000 individuals in the U.S., with approximately 2,800 new cases seen annually.

Dusquetide

Dusquetide (research name: SGX94) is an innate defense regulator (“IDR”) that regulates the innate immune system to simultaneously reduce inflammation, eliminate infection and enhance tissue healing.

Dusquetide is based on a new class of short, synthetic peptides known as IDRs. It has a novel mechanism of action in that it modulates the body’s reaction to both injury and infection and is both simultaneously anti-inflammatory and anti-infective. IDRs have no direct antibiotic activity but modulate host responses, increasing survival after infections with a broad range of bacterial Gram-negative and Gram-positive pathogens including both antibiotic sensitive and resistant strains, as well as accelerating resolution of tissue damage following exposure to a variety of agents including bacterial pathogens, trauma and chemo- or radiation-therapy. IDRs represent a novel approach to the control of infection and tissue damage via highly selective binding to an intracellular adaptor protein, sequestosome-1, also known as p62, which has a pivotal function in signal transduction during activation and control of the innate defense system. Preclinical data indicate that IDRs may be active in models of a wide range of therapeutic indications including life-threatening bacterial infections as well as the severe side-effects of chemo- and radiation-therapy. Additionally, due to selective binding to p62, dusquetide may have potential anti-tumor action.

Dusquetide has demonstrated efficacy in numerous animal disease models including mucositis, colitis, skin infection and other bacterial infections and has been evaluated in a double-blind, placebo-controlled Phase 1 clinical trial in 84 healthy volunteers with both single ascending dose and multiple ascending dose components. Dusquetide was shown to have a good safety profile and be well-tolerated in all dose groups when administered by IV over 7 days and was consistent with safety results seen in pre-clinical studies. ~~Dusquetide is the subject of an open Investigational New Drug (“IND”) application which has been cleared by the FDA.~~ We believe that market opportunities for dusquetide include, but are not limited to, oral and ~~gastrointestinal~~GI mucositis, acute Gram-positive bacterial infections (e.g., methicillin resistantStaphylococcus aureus (MRSA)), acute Gram-negative infections (e.g., acinetobacter, melioidosis), and acute radiation syndrome.

SGX942 – for Treating Oral Mucositis in Head and Neck Cancer

SGX942 is our product candidate containing our IDR technology, dusquetide, targeting the treatment of oral mucositis in head and neck cancer patients. Oral mucositis in this patient population is an area of unmet medical need where there are currently no approved drug therapies. Accordingly, we received Fast Track designation for the treatment of oral mucositis as a result of radiation and/or chemotherapy treatment in head and neck cancer patients from the FDA. In addition, dusquetide has been granted PIM designation in the UK by the MHRA for the treatment of severe oral mucositis in head and neck cancer patients receiving chemoradiation therapy. The U.S. Patent and Trademark Office and the European Patent Office granted us the patent titled “Novel Peptides and Analogs for Use in the Treatment of Oral Mucositis” on August 16, 2016 and January 23, 2019, respectively. The newly issued patent claims therapeutic use of dusquetide and related IDR analogs, and adds to composition of matter claims for dusquetide and related analogs that have been granted in the U.S. and worldwide.

We initiated a Phase 2 clinical study of SGX942 for the treatment of oral mucositis in head and neck cancer patients in December of 2013. We completed enrollment in this trial in the second half of 2015, and in December 2015 released positive preliminary results. In this Phase 2 proof-of-concept clinical study that enrolled 111 patients, SGX942, at a dose of 1.5 mg/kg, successfully reduced the median duration of severe oral mucositis by 50%, from 18 days to 9 days (p=0.099) in all patients and by 67%, from 30 days to 10 days (p=0.040) in patients receiving the most aggressive chemoradiation therapy for treatment of their head and neck cancer. The p-values met the prospectively defined statistical threshold of p<0.1 in the study protocol. A less severe occurrence of oral mucositis, ulcerative oral mucositis (defined as oral mucositis with a WHO score ≥2 corresponding to the occurrence of overt ulceration in the mouth), was also monitored during the study. In the patients receiving the most aggressive chemoradiation therapy, the median duration of oral mucositis was found to decrease from 65 days in the placebo treated patients to 51 days in the patients treated with SGX942 1.5 mg/kg (p=0.099).

In addition to identifying the best dose of 1.5 mg/kg, this study achieved all objectives, including increased incidence of “complete response” of tumor at the one month follow-up visit (47% in placebo vs. 63% in SGX942 at 1.5 mg/kg). Decreases in mortality and decreases in infection rate were also observed with SGX942 treatment, consistent with the preclinical results observed in animal models.

SGX942 was found to be generally safe and well tolerated, consistent with the safety profile observed in the prior Phase 1 study conducted in 84 healthy volunteers. The long-term (12 month) follow-up data was consistent with the preliminary positive safety and efficacy findings. While the placebo population experienced the expected 12-month survival rate of approximately 80%, as defined in the Surveillance, Epidemiology, and End Results statistics 1975-2012 from the National Cancer Institute, the SGX942 1.5 mg/kg treatment group reported a 12-month survival rate of 93% (7% mortality in the SGX942 1.5 mg/kg group compared to 19% in the placebo group). Similarly, tumor resolution (complete response) at 12 months was better in the SGX942 1.5 mg/kg treatment group relative to the placebo population (80% in the 1.5 mg/kg group compared to 74% in the placebo group). Moreover, in the patients receiving chemotherapy every third week, the SGX942 1.5 mg/kg treatment group had a tumor resolution rate (complete response) of 82% throughout the 12 months following chemoradiation therapy, while the placebo group experienced a 64% complete response rate. The long-term follow-up results from the Phase 2 study are reviewed in “Dusquetide: Reduction in Oral Mucositis associated with Enduring Ancillary Benefits in Tumor Resolution and Decreased Mortality in Head and Neck Cancer Patients” published online in Biotechnology Reports and available at the following link:https://doi.org/10.1016/~~j.btre.2017.05.002~~.j.btre.2017.05.002. In addition to safety, evaluations of other secondary efficacy endpoints, such as the utilization of opioid pain medication, indicated that the SGX942 1.5mg/kg treatment group had a 40% decrease in the use of opioids at the later stage of the treatment phase of the trial, when oral mucositis is usually most severe and expected to increase ~~paid~~pain medication use. This was in contrast to the placebo group, which demonstrated a 10% increase in use of opioids over this same period. Data from this Phase 2 trial was published online in the Journal of Biotechnology. The publication also delineates the supportive nonclinical data in this indication, demonstrating consistency in the qualitative and quantitative biological response, including dose response, across the nonclinical and clinical data sets. The results are available at the following link:~~http:~~ https://~~authors.elservier.com/sd/~~www.sciencedirect.com/science/article/~~S01681656116315668~~.pii/S0168165616315668?via%3Dihub.

On September 9, 2016, we and SciClone Pharmaceuticals, Inc. (“SciClone”) entered into an exclusive license agreement, pursuant to which we granted rights to SciClone to develop, promote, market, distribute and sell SGX942 in defined territories. Under the terms of the license agreement, SciClone will be responsible for all aspects of development, product registration and commercialization in the territories, having access to data generated by us. In exchange for exclusive rights, SciClone will pay us royalties on net sales, and we will supply commercial drug product to SciClone on a cost-plus basis, while maintaining worldwide manufacturing rights.

We have received clearance from the FDA to advance the pivotal Phase 3 protocol for SGX942 in the treatment of oral mucositis in patients with head and neck cancer receiving chemoradiation therapy. Additionally, we have received positive Scientific Advice from the EMA for the development of SGX942 as a treatment for oral mucositis in patients with head and neck cancer. The Scientific Advice from the EMA indicates that a single, double-blind, placebo-controlled, multinational, Phase 3 pivotal study, if successful, in conjunction with the Phase 2 dose-ranging study, is generally considered sufficient to support a marketing authorization application (“MAA”) to the EMA for potential licensure in Europe. The advice also provided several suggestions to strengthen the study design and data collection that ~~will be~~were integrated into the final protocol. Scientific Advice is offered by the EMA to stakeholders for clarification of questions arising during development of medicinal products. The scope of Scientific Advice is limited to scientific issues and focuses on development strategies rather than pre-evaluation of data to support an MAA. Scientific Advice is legally non-binding and is based on the current scientific knowledge which may be subject to future changes.

We ~~had been~~are working with leading oncology centers, a number of which participated in the Phase 2 study, to advance this Phase 3 clinical trial referred to as the “DOM–INNATE” study (Dusquetide treatment inOralMucositis – by modulatingINNATE immunity). Based on the positive and previously published Phase 2 results (Study IDR-OM-01), the pivotal Phase 3 clinical trial (Study IDR-OM-02) ~~will be~~is a highly powered, double-blind, randomized, placebo-controlled, multinational trial that ~~will seek to enroll approximately 190~~enrolled 268 subjects with squamous cell carcinoma of the oral cavity and oropharynx who ~~are~~were scheduled to receive a minimum total cumulative radiation dose of 55 Gy fractionated as 2.0-2.2 Gy per day with concomitant cisplatin chemotherapy given as a dose of 80-100 mg/m² every third week. Subjects ~~will be~~were randomized to receive either 1.5 mg/kg SGX942 or placebo given twice a week during and for two weeks following completion of chemoradiation therapy (“CRT”). The primary endpoint for the study ~~will be~~is the median duration of severe oral mucositis, which ~~will be~~is assessed by oral examination at each treatment visit and then through six weeks following completion of CRT. Oral mucositis ~~will be~~is evaluated using the WHO Grading system. Severe oral mucositis is defined as a WHO Grade of ≥3. Subjects ~~will be~~are followed for an additional 12 months after the completion of treatment.

During July 2017, we initiated our pivotal Phase 3 study with a controlled roll-out of U.S. study sites, ~~and will follow with~~followed by the addition of European centers in 2018. Approximately 50 U.S. and European oncology centers are participating in this pivotal Phase 3 study.

During September 2017, the National Institute of Dental and Craniofacial Research (“NIDCR”), part of the NIH, awarded us a SBIR grant of approximately $1.5 million over two years to support the conduct of our Phase 3, multinational, randomized, double-blind, placebo-controlled study evaluating SGX942 (dusquetide) as a treatment for severe oral mucositis in patients with head and neck cancer receiving CRT. This grant has been exhausted as of August 2019.

On April 9, 2019, the U.S. Patent Office issued a new patent No. 10,253,068 titled “Novel Peptides for Treating and Preventing Immune-Related Disorders, Including Treating and Preventing Infection by Modulating Innate Immunity” for our dusquetide related analogs.

In April 2019, the Pediatric Committee of the EMA approved our Pediatric Investigation Plan (“PIP”) for SGX942, a prerequisite for filing a Marketing Authorization Application (“MAA”) for any new medicinal product in Europe. The EMA also agreed that we may defer conducting the PIP until successful completion of our ongoing pivotal Phase 3 clinical trial of SGX942, which allows us to file the adult indication MAA prior to completion of the PIP.

During August 2019, an independent DMC completed an unblinded interim analysis with data from approximately 90 subjects, including an assessment of the Phase 3 DOM-INNATE study’s primary efficacy endpoint. The DMC provided a positive recommendation to randomize approximately 70 additional subjects into the trial to maintain the rigorous assumption of 90% statistical power for the primary efficacy endpoint. No safety concerns were reported by the DMC based on the interim analysis.

In June 2020, enrollment of 268 subjects was completed. We currently anticipate final top-line results during the fourth quarter 2020.

In August 2019, the NIDCR, part of the NIH, awarded us a Phase 1 SBIR grant of approximately $150,000 to support the evaluation of SGX942 (dusquetide) in pediatric indications. This award will facilitate the assessment of SGX942 safety in juvenile animals, supporting future studies in pediatric populations, including oral mucositis indications in pediatric patients undergoing stem cell transplants and treatments for head and neck cancer.

In February 2020, the Japanese Patent Office granted the patent titled “Novel Peptides and Analogs for Use in the Treatment of Oral Mucositis.” This allowance builds on similar intellectual property in the U.S., New Zealand, Australia and Singapore and patent applications pending in other jurisdictions worldwide. The new claims cover therapeutic use of dusquetide (active ingredient in SGX942) and related IDR analogs, and add to composition of matter claims for dusquetide and related analogs that have been granted in the U.S. and worldwide.

We estimate the potential worldwide market for SGX942 is in excess of $500 million for all applications, including the treatment of oral mucositis. This potential market information is a forward-looking statement, and investors are urged not to place undue reliance on this statement. While we have determined this potential market size based on assumptions that we believe are reasonable, there are a number of factors that could cause our expectations to change or not be realized.

Oral Mucositis

Mucositis is the clinical term for damage done to the mucosa by anticancer therapies. It can occur in any mucosal region, but is most commonly associated with the mouth, followed by the small intestine. We estimate, based upon our review of historic studies and reports, and an interpolation of data on the incidence of mucositis, that mucositis affects approximately 500,000 people in the U.S. per year and occurs in 40% of patients receiving chemotherapy. Mucositis can be severely debilitating and can lead to infection, sepsis, the need for parenteral nutrition and narcotic analgesia. The GI damage causes severe diarrhea. These symptoms can limit the doses and duration of cancer treatment, leading to sub-optimal treatment outcomes.

The mechanisms of mucositis have been extensively studied and have been ~~recently~~ linked to the interaction of chemotherapy and/or radiation therapy with the innate defense system. Bacterial infection of the ulcerative lesions is regarded as a secondary consequence of dysregulated local inflammation triggered by therapy-induced cell death, rather than as the primary cause of the lesions.

We estimate, based upon our review of historic studies and reports, and an interpolation of data on the incidence of oral mucositis, that oral mucositis is a subpopulation of approximately 90,000 patients in the U.S., with a comparable number in Europe. Oral mucositis almost always occurs in patients with head and neck cancer treated with radiation therapy (greater than 80% incidence of severe mucositis) and is common in patients undergoing high dose chemotherapy and hematopoietic cell transplantation, where the incidence and severity of oral mucositis depends greatly on the nature of the conditioning regimen used for myeloablation.

Oral BDP

~~Oral BDP~~

Oral BDP (beclomethasone 17,21-dipropionate) represents a first-of-its-kind oral, locally acting therapy tailored to treat GI inflammation. BDP has been marketed in the U.S. and worldwide since the early 1970s as the active pharmaceutical ingredient in a nasal spray and in a metered-dose inhaler for the treatment of patients with allergic rhinitis and asthma. Oral BDP is specifically formulated for oral administration as a single product consisting of two tablets. One tablet is intended to release BDP in the upper sections of the GI tract and the other tablet is intended to release BDP in the lower sections of the GI tract.

Based on its pharmacological characteristics, oral BDP may have utility in treating other conditions of the ~~gastrointestinal~~GI tract having an inflammatory component. We are planning to pursue development programs for the treatment of pediatric Crohn’s disease, acute radiation enteritis and GI ~~ARS~~acute radiation syndrome pending further grant funding. We are also exploring the possibility of testing oral BDP for local inflammation associated with ulcerative colitis, among other indications.

~~We are pursuing Orphan Drug designations~~In July 2019, the European Patent Office issued two patents, both titled “Topically Active Steroids for ~~relevant indications~~use in Radiation and Chemotherapeutic Injury”, following the expiration of the objection period. The new patents (#2,373,160 and #2,902,031) claim use of oral beclomethasone 17,21-dipropionate (BDP) for treatment of damage to the GI tract as ~~appropriate in both the U.S. and Europe. An Orphan Drug designation provides for seven years~~a result of ~~market exclusivity upon approval~~acute radiation injury, including total body irradiation in the ~~U.S. and Europe, respectively.~~

~~SGX203 – for Treating Pediatric Crohn’s Disease~~

We estimate the potential worldwide market for oral BDP is in excess of $500 million for all applications, including the treatment of pediatric Crohn’s disease. This potential market information is a forward-looking statement, and investors are urged not to place undue reliance on this statement. While we have determined this potential market size based on assumptions that we believe are reasonable, there are a number of factors that could cause our expectations to change or not be realized.

SGX203 – for Treating Pediatric Crohn’s Disease

SGX203 is a two tablet delivery system of BDP specifically designed for oral use that allows for administration of immediate and delayed release BDP throughout the small bowel and the colon. The FDA has given SGX203 Orphan Drug designation as well as Fast Track designation for the treatment of pediatric Crohn’s disease. We will pursue a pivotal Phase 3 clinical trial of SGX203 for the treatment of pediatric Crohn’s disease contingent upon additional funding, such as through partnership funding support.

Pediatric Crohn’s Disease

Crohn’s disease causes inflammation of the GI tract. Crohn’s disease can affect any area of the GI tract, from the mouth to the anus, but it most commonly affects the lower part of the small intestine, called the ileum. The swelling caused by the disease extends deep into the lining of the affected organ. The swelling can induce pain and can make the intestines empty frequently, resulting in diarrhea. Because the symptoms of Crohn’s disease are similar to other intestinal disorders, such as irritable bowel syndrome and ulcerative colitis, it can be difficult to diagnose. People of Ashkenazi Jewish heritage have an increased risk of developing Crohn’s disease.

Crohn’s disease can appear at any age, but it is most often diagnosed in adults in their 20s and 30s. However, approximately 30% of people with Crohn’s disease develop symptoms before 20 years of age. We estimate, based upon our review of historic published studies and reports, and an interpolation of data on the incidence of pediatric Crohn’s disease, that pediatric Crohn’s disease is a subpopulation of approximately 80,000 patients in the U.S. with a comparable number in Europe. Crohn’s disease tends to be both severe and extensive in the pediatric population and a relatively high proportion (approximately 40%) of pediatric Crohn’s patients have involvement of their upper ~~gastrointestinal~~GI tract.

Crohn’s disease presents special challenges for children and teens. In addition to bothersome and often painful symptoms, the disease can stunt growth, delay puberty, and weaken bones. Crohn’s disease symptoms may sometimes prevent a child from participating in enjoyable activities. The emotional and psychological issues of living with a chronic disease can be especially difficult for young people.

SGX201 – for Preventing Acute Radiation Enteritis

SGX201 is a delayed-release formulation of BDP specifically designed for oral use. In 2012, we completed a Phase 1/2 clinical trial testing SGX201 in prevention of acute radiation enteritis. Patients with rectal cancer scheduled to undergo concurrent radiation and chemotherapy prior to surgery were randomized to one of four dose groups. The objectives of the study were to evaluate the safety and maximal tolerated dose of escalating doses of SGX201, as well as the preliminary efficacy of SGX201 for prevention of signs and symptoms of acute radiation enteritis. The study demonstrated that oral administration of SGX201 was safe and well tolerated across all four dose groups. There was also evidence of a potential dose response with respect to diarrhea, nausea and vomiting and the assessment of enteritis according to National Cancer Institute Common Terminology Criteria for Adverse Events for selected ~~gastrointestinal~~GI events. In addition, the incidence of diarrhea was lower than that seen in ~~recent~~ published historical control data in this patient population. This program was supported in part by a $500,000 two-year SBIR grant awarded by the NIH. We continue to work with our Radiation Enteritis medical advisors to identify additional funding opportunities to support the clinical development program.

We have received Fast Track designation from the FDA for SGX201 for acute radiation enteritis.

We estimate the potential worldwide market for oral BDP is in excess of $500 million for all applications, including the treatment of acute radiation enteritis. This potential market information is a forward-looking statement. While we have determined this potential market size based on assumptions that we believe are reasonable, there are a number of factors that could cause our expectations to change or not be realized.

Acute Radiation Enteritis

External radiation therapy is used to treat most types of cancer, including cancer of the bladder, uterine, cervix, rectum, prostate, and vagina. During delivery of treatment, some level of radiation will also be delivered to healthy tissue, including the bowel, leading to acute and chronic toxicities. The large and small bowels are very sensitive to radiation and the larger the dose of radiation the greater the damage to normal bowel tissue. Radiation enteritis is a condition in which the lining of the bowel becomes swollen and inflamed during or after radiation therapy to the abdomen, pelvis, or rectum. Most tumors in the abdomen and pelvis need large doses, and almost all patients receiving radiation to the abdomen, pelvis, or rectum will show signs of acute enteritis.

Patients with acute enteritis may have nausea, vomiting, abdominal pain and bleeding, among other symptoms. Some patients may develop dehydration and require hospitalization. With diarrhea, the ~~gastrointestinal~~GI tract does not function normally, and nutrients such as fat, lactose, bile salts, and vitamin B12 are not well absorbed.

Symptoms will usually resolve within two to six weeks after therapy has ceased. Radiation enteritis is often not a self-limited illness, as over 80% of patients who receive abdominal radiation therapy complain of a persistent change in bowel habits. Moreover, acute radiation injury increases the risk of development of chronic radiation enteropathy, and overall 5% to 15% of the patients who receive abdominal or pelvic irradiation will develop chronic radiation enteritis.

We estimate, based upon our review of historic published studies and reports, and an interpolation of data on the treatment courses and incidence of cancers occurring in the abdominal and pelvic regions, there to be over 100,000 patients annually in the U.S., with a comparable number in Europe, who receive abdominal or pelvic external beam radiation treatment for cancer, and these patients are at risk of developing acute and chronic radiation enteritis.

~~Vaccines/BioDefense~~Public Health Solutions Overview

ThermoVax^®– Thermostability Technology

~~Our thermostability technology,~~ ThermoVax^®, is a novel method for thermostabilizing vaccines with a variety of ~~rendering~~adjuvants, resulting in a single vial which can be reconstituted with water for injection immediately prior to use.

One of the adjuvants utilized in ThermoVax^® is aluminum ~~salt,~~salts (known colloquially as Alum)~~, adjuvanted vaccines stable at elevated temperatures.~~. Alum is the most widely employed adjuvant technology in the vaccine industry.

The value of ThermoVax^® lies in its potential ability to eliminate the need for cold chain production, transportation, and storage for ~~Alum adjuvanted~~Alum-adjuvanted vaccines. This would relieve ~~companies of~~ the high costs of producing and maintaining vaccines under refrigerated conditions. Based on historical reports from the World Health Organization and other scientific reports, we believe that a meaningful proportion of vaccine doses globally are wasted due to excursions from required cold chain temperature ranges. This is due to the fact that ~~most Alum adjuvanted~~many vaccines need to be maintained ateither between 2 and 8 degrees Celsius (“C”), frozen below -20 degrees C, or frozen below -60 degrees C, and even brief excursions from ~~this~~these temperature ~~range (especially below freezing)~~ranges usually ~~necessitates~~necessitate the destruction of the product or the initiation of costly stability programs specific for the vaccine lots in question. We believe that the savings realized from the elimination of cold chain costs and related product losses would significantly increase the profitability of vaccine products. We believe that elimination of the cold chain could further facilitate the use of these vaccines in the lesser developed parts of the world. ThermoVax^® has the potential to facilitate easier storage and distribution of strategic national stockpile vaccines for ricin exposure in emergency settings.

ThermoVax^®development, specifically in the context of an Alum adjuvant, was supported pursuant to our $9.4 million NIAID grant enabling development of thermo-stable ricin (RiVax^®) and anthrax ~~(VeloThrax~~^®) vaccines. Proof-of-concept preclinical studies with ThermoVax^®indicate that it is able to produce stable vaccine formulations using adjuvants, protein immunogens, and other components that ordinarily would not withstand long temperature variations exceeding customary refrigerated storage conditions. These studies were conducted with our ~~aluminum-adjuvanted~~Alum-adjuvanted ricin toxin vaccine, RiVax^® and our ~~aluminum-adjuvanted~~Alum-adjuvanted anthrax ~~vaccine, VeloThrax~~^®.vaccine. Each vaccine was manufactured under precise lyophilization conditions using excipients that aid in maintaining native protein structure of the key antigen. When RiVax^® was kept at 40 degrees C (104 degrees Fahrenheit) for up to one year, all of the animals vaccinated with the lyophilized RiVax^® vaccine developed potent and high titer neutralizing antibodies. In contrast, animals that were vaccinated with the liquid RiVax^® vaccine kept at 40 degrees C did not develop neutralizing antibodies and were not protected against ricin exposure. The ricin A chain is extremely sensitive to temperature and rapidly loses the ability to induce neutralizing antibodies when exposed to temperatures higher than 8 degrees C. When ~~VeloThrax~~^®the anthrax vaccine was kept for up to 16 weeks at 70 degrees C, it was able to develop a potent antibody response, unlike the liquid formulation kept at the same temperature. Moreover, we also have demonstrated the compatibility of our thermostabilization technology with other secondary adjuvants such as TLR-4 agonists. Additionally, the University of Colorado conducted a study that demonstrated a heat stable vaccine formulation of a human papillomavirus (“HPV”) vaccine. The work was conducted by Drs. Randolph and Garcea and demonstrated the successful conversion of a commercial virus-like-particle based vaccine requiring cold chain storage to a subunit, alum-adjuvanted, vaccine which is stable at ambient temperatures. This work, funded by a University of Colorado seed grant and the Specialized Program of Research Excellence in cervical cancer, is the first demonstration of the utility of ThermoVax^® technology for the development of a subunit based commercial vaccine. The HPV vaccine formulation was found to be stable for at least 12 weeks at 50 degrees C. In the study, mice immunized with the ThermoVax^®~~-stabilized HPV subunit vaccine were also found to achieve immune responses similar to the commercial HPV vaccine, Cervarix~~^®~~, as measured by either total antibody levels or neutralizing antibody levels. Moreover, whereas the immune responses to Cervarix~~^®~~were reduced after storage for 12 weeks at 50 degrees C, the ThermoVax~~^® ~~formulated vaccine retained its efficacy. The results were published online in the European Journal of Pharmaceutics and Biopharmaceutics. Seehttp://www.sciencedirect.com/science/article/pii/S0939641115002416~~).

We also entered into a collaboration agreement with Axel Lehrer, PhD of the Department of Tropical Medicine, Medical Microbiology and Pharmacology, John A. Burns School of Medicine, University of Hawaiʻi at Manoa (“UH Manoa”) and Hawaii Biotech, Inc. (“HBI”) to develop a heat stable subunit Ebola vaccine. Dr. Lehrer, a co-inventor of the Ebola vaccine with HBI, has shown proof of concept efficacy with subunit Ebola vaccines in non-human primates. The most advanced Ebola vaccines involve the use of vesicular stomatitis virus and adenovirus vectors – live, viral vectors which complicate the manufacturing, stability and storage requirements. Dr. Lehrer’s vaccine candidate is based on highly purified recombinant protein antigens, circumventing many of these manufacturing difficulties. Dr. Lehrer and HBI have developed a robust manufacturing process for the required proteins. Application of ThermoVax^® may allow for a product that can avoid the need for cold chain distribution and storage, yielding a vaccine ideal for use in both the developed and developing world. ~~Although this~~This agreement has expired in accordance with its ~~terms, we expect to extend the period of the agreement or enter into another agreement with Dr. Lehrer and HBI to replace this agreement.~~terms.

During September 2017, we announced we will be participating in a NIAID Research Project (R01) grant awarded to ~~the University of Hawai’i at~~UH Manoa for the development of a trivalent thermostabilized ~~Ebola~~filovirus vaccine (including protection against Zaire ebolavirus, Sudan ebolavirus and Marburg Marburgvirus), with our awarded funding of approximately $700,000 over 5five years. Previous collaborations demonstrated the feasibility of developing a heat stable subunit Ebola vaccine. Under the terms of the subaward, we will continue to support vaccine formulation development with our proprietary vaccine thermostabilization technology, ThermoVax^®. Ultimately, the objective is to produce a thermostable trivalent filovirus vaccine for protection against Ebola and related diseases, allowing worldwide distribution without the need for cold storage. Based on current U.S. government needs, efforts have recently been expanded to focus on a monovalent or bivalent vaccine to specifically address Marburg marburgvirus.

~~We intend~~On December 21, 2010, we executed a worldwide exclusive license agreement with the University of Colorado (“UC”) for certain patents relating to seek out potential partnerships with companies marketing FDA/ex-U.S. health authority approved Alum adjuvanted vaccines and currently developing Alum adjuvanted vaccines that are interested in eliminating the need for cold chain for their products. We believe that ThermoVax^® ~~also will enable~~in all fields of use. In April 2018, the UC delivered a notice of termination of our license agreement based upon our failure to achieve one of the development milestones: initiation of the Phase 1 clinical trial of the heat stabilization technology by March 31, 2018. After negotiating with the UC, we and the UC agreed to extend the termination date to October 31, 2018 in order to allow us time to agree upon a potential agreement that would allow us to ~~expand~~keep the rights to, and to continue to develop, the heat stabilization technology or a product candidate containing the heat stabilization technology in our field of use.

On October 31, 2018, in a series of related transactions, (a) we and the UC agreed to terminate the original license agreement, (b) the UC and VitriVax, Inc. (“VitriVax”) executed a worldwide exclusive license agreement for the heat stabilization technology for all fields of use, and (c) we and VitriVax executed a worldwide exclusive sublicense agreement for the heat stabilization technology for use in the fields of ricin and Ebola vaccines. We paid a $100,000 sublicense fee on the effective date of the sublicense agreement. To maintain the sublicense we are obliged to pay a minimum annual royalty of $20,000 until first commercial sale of a sublicensed product, upon which point, we shall pay an earned royalty of 2% of net sales subject to a minimum royalty of $50,000 each year. We are also required to pay royalty on any sub-sublicense income based on a declining percentage of all sub-sublicense income calculated within the contractual period until reaching a minimum of 15% after two years. In addition, we are required to pay VitriVax milestone fees of: (a) $50,000 upon initiation of a Phase 2 clinical trial of the sublicensed product, (b) $200,000 upon regulatory approval of a sublicensed product, and (c) $1 million upon achieving $10 million in aggregate net sales of a sublicensed product in the U.S. or equivalent. To date none of these milestones have been met.

On February 7, 2019, European Journal of Pharmaceutics and Biopharmaceutics published a scientific article demonstrating the successful thermostabilization of an Alum-adjuvanted Ebola subunit vaccine ~~development expertise beyond biodefense into~~candidate.

On July 31, 2019, we and our collaborators presented two posters on the ~~infectious disease space~~trivalent vaccine program. The first poster outlined the stability of the lyophilized formulations of the Ebola virus glycoprotein upon lyophilization and ~~also has~~storage at temperatures as high as 40 degrees C (104 degrees F) and identified potential stability assays. The second poster further demonstrated the ~~potential~~ability to ~~allow for~~co-lyophilize multiple antigens in the presence of an emulsion forming adjuvant, facilitating the development of ~~multivalent vaccines (e.g., combination ricin-anthrax vaccine).~~a thermostable trivalent vaccine.

On March 11, 2020, we entered into a research collaboration with the Axel Lehrer, PhD of the Department of Tropical Medicine, Medical Microbiology and Pharmacology, John A. Burns School of Medicine, UH Manoa to further expand the filovirus collaboration to investigation of potential coronavirus vaccines, including for SARS-CoV-2 (causing COVID-19). This research collaboration will utilize the technology platform developed in the search for filovirus vaccines and will use well-defined surface glycoprotein(s) from one or more coronaviruses, which are expected to be protective for COVID-19.

On April 16, 2020, we obtained an exclusive worldwide license for CoVaccine HT^TM, a novel vaccine adjuvant, from BTG Specialty Pharmaceuticals (“BTG”), a division of Boston Scientific Corporation, for the fields of coronavirus infection (including SARS-CoV-2, the cause of COVID-19), and pandemic flu. CoVaccine HT^TMis a novel adjuvant, which has been shown to enhance both cell-mediated and antibody-mediated immunity. We and our collaborators, including UH Manoa and Dr. Axel Lehrer, have successfully demonstrated the utility of CoVaccine HT^TMin the development of our heat stable filovirus vaccine program, with vaccine candidates against Ebola and Marburg virus disease. Given this previous success, CoVaccine HT^TM will potentially be an important component of our vaccine technology platform currently being assessed for use against coronaviruses including SARS-CoV-2, the cause of COVID-19. The license agreement was executed between us and Protherics Medicines Development, one of the companies that make up the BTG specialty pharmaceutical business, which owns the CoVaccine HT^TM intellectual property.

On July 28, 2020, we announced the availability of a pre-print manuscript (available at https://doi.org/10.1101/2020.07.24.220715) describing a prototype COVID-19 vaccine using the novel CoVaccine HT™ adjuvant and demonstrating significant immunogenicity, including strong total and neutralizing antibody responses, with a balanced Th1 response, as well as enhancement of cell mediated immunity. These are all considered to be critical attributes of a potential COVID-19 vaccine.

RiVax^®– Ricin Toxin Vaccine

RiVax^®is our proprietary vaccine candidate being developed to protect against exposure to ricin toxin and if approved, would be the first ricin vaccine. The immunogen in RiVax^® induces a protective immune response in animal models of ricin exposure and functionally active antibodies in humans. The immunogen consists of a genetically inactivated ricin A chain subunit that is enzymatically inactive and lacks residual toxicity of the holotoxin. RiVax^® has demonstrated statistically significant (p < 0.0001) preclinical survival results, providing 100% protection against acute lethality in an aerosol exposure non-human primate model (Roy et al, 2015, Thermostable ricin vaccine protects rhesus macaques against aerosolized ricin: Epitope-specific neutralizing antibodies correlate with protection, PNAS USA 112:3782-3787), and has also been shown to be well tolerated and immunogenic in two Phase 1 clinical trials in healthy volunteers. Results of the first Phase 1 human trial of RiVax^® established that the immunogen was safe and induced antibodies that we believe may protect humans from ricin exposure. The antibodies generated from vaccination, concentrated and purified, were capable of conferring immunity passively to recipient animals, indicating that the vaccine was capable of inducing functionally active antibodies in humans. The outcome of this study was published in the Proceedings of the National Academy of Sciences (Vitetta et al., 2006, A Pilot Clinical Trial of a Recombinant Ricin Vaccine in Normal Humans, PNAS, 103:2268-2273). The second trial which was completed in September 2012 and was sponsored by University of Texas Southwestern Medical Center (“UTSW”), evaluated a more potent formulation of RiVax^® that contained an ~~aluminum adjuvant (Alum).~~Alum adjuvant. The results of the Phase 1b study indicated that Alum-adjuvanted RiVax^® was safe and well tolerated, and induced greater ricin neutralizing antibody levels in humans than adjuvant-free RiVax^®. The outcomes of this second study were published in the Clinical and Vaccine Immunology (Vitetta et al., 2012, Recombinant Ricin Vaccine Phase 1b Clinical Trial, Clin. Vaccine Immunol. 10:1697-1699). We have adapted the original manufacturing process for the immunogen contained in RiVax^®for thermostability and large scale manufacturing and recent studies have confirmed that the thermostabilized RiVax^®formulation ~~significantly~~ enhances the stability of the ~~RiVax®~~RiVax^® antigen, enabling storage for at least 1 year at temperatures up to 40°C (104 °F). The program will pursue approval via the FDA “Animal Rule” since it is not possible to test the efficacy of the vaccine in a clinical study which would expose humans to ricin. Uniform, easily measured and species-neutral immune correlates of protection that can be measured in humans and animals, and are indicative of animal survival to subsequent ricin challenge, are central to the application of the “Animal Rule”. Recent work has identified such potential correlates of immune protection in animals and work to qualify and validate these approaches is continuing, with the goal of utilizing these assays in a planned Phase 1/2 clinical trial with the thermostable ~~RiVax®~~RiVax^® formulation. During September 2018, we published an extended stability study of RiVax^®, showing up to 100% protection in mice after 12 months storage at 40°C (104 °F) as well as identification of a potential in vitro stability indicating assay, critical to adequately confirming the long-term shelf life of the vaccine. We have entered into a collaboration with IDT Biologika GmbH to scale-up the formulation/filling process and continue development and validation of analytical methods established at IDT to advance the program. We also have initiated a development agreement with Emergent BioSolutions, Inc. to implement a commercially viable, scalable production technology for the RiVax^®drug substance protein antigen.

The development of RiVax^® has been sponsored through a series of overlapping challenge grants, UC1, and cooperative grants, U01, from the NIH, granted to ~~Soligenix~~us and to UTSW where the vaccine originated. The second clinical trial was supported by a grant from the FDA’s Office of Orphan Products to UTSW. To date, we and UTSW have collectively received approximately $25 million in grant funding from the NIH for the development of RiVax^®. In September 2014, we entered into a contract with the NIH for the development of RiVax^® ~~that would provide up~~pursuant to which we have been awarded an additional ~~$24.7~~$21.2 million of funding in the ~~aggregate if options to extend the contract are exercised by the NIH.~~aggregate. The development agreements with Emergent BioSolutions and IDT are specifically funded under this NIH contract.

~~During June~~In 2017, NIAID exercised ~~an option for the evaluation of RiVax~~^®options to fund additional animal efficacy ~~studies. The exercised option will provide us with approximately $2.0 million in additional funding. Additionally, during August 2017 NIAID exercised an option to fund GMP (good~~studies and good manufacturing ~~practices)~~practices compliant RiVax^®bulk drug substance and finished drug product manufacturing, which is required for the conduct of future preclinical and clinical safety and efficacy studies. The exercised ~~option will~~options provide us with approximately ~~$2.5~~$4.5 million in additional non-dilutive funding, bringing the total amount awarded to date under this contract to $21.2 million, of which ~~$17.9~~$1.1 million is still available. ~~If all contract options are exercised, the~~The total award of up to ~~$24.7~~$21.2 million will support the preclinical, manufacturing and clinical development activities necessary to advance heat stable RiVax^® with the ~~U.S.~~ FDA. In addition to the ongoing funding of $21.2 million for the development of RiVax^®, biomarkers for RiVax^®testing have been successfully identified, facilitating potential approval under the FDA Animal Rule.

During December 2019, we initiated a third Phase 1 double-blind, placebo-controlled, randomized study in eight healthy adult volunteer subjects designed to evaluate the safety and immunogenicity of RiVax^® utilizing ThermoVax^®. During January 2020, we suspended the study after Emergent Manufacturing Operations Baltimore LLC (“EMOB”), the manufacturer of the drug substance, notified us that, after releasing of the final drug product to us, EMOB identified that the active drug substance tested outside the established specification parameters. Two subjects had received doses as part of the study before the manufacturer provided this notice. Those two subjects will continue to be monitored and data captured in accordance with the study protocol; however, they will not receive further doses of study drug. A clinical safety report will be generated at study completion.

During April 2020, we received notification from NIAID that they would not be exercising the final contract option to support the conduct of a Phase 1/2 clinical study in healthy volunteers. As a result, the total contract award will not exceed $21.2 million.

In connection with failures relating to the manufacture of RiVax^® bulk drug substance, on July 1, 2020, we filed a demand for arbitration against Emergent Biosolutions, Inc. (“EBS”), Emergent Product Development Gaithersburg, Inc. (“EPDG”); and EMOB (together with EBS and EPDG, “Emergent”) with the American Arbitration Association in Mercer County, New Jersey. We have alleged that (a) EPDG breached contracts, an express warranty, a warranty of merchantability, and a warranty of fitness for a particular purpose, (b) EMOB breached a contract; (c) EPDG was unjustly enriched; (d) EPDG and EMOB were negligent in the performance of their work; and (e) EBS fraudulently induced us into entering into the contracts with EPDG and EMOB. We are seeking to recover damages in excess of $19 million from Emergent. Emergent has answered the demand for arbitration denying the allegations and asserting affirmative defenses. While we intend to vigorously pursue this arbitration, we cannot offer any assurances as to any result from the arbitration or that we will recover any damages from Emergent. For more details regarding the arbitration against Emergent, see Part II – Item 1. “Legal Proceedings” in this Quarterly Report.

RiVax^®has been granted Orphan Drug designation as well as Fast Track designation by the FDA for the prevention of ricin intoxication. In addition, RiVax^®has also been granted Orphan Drug designation in the European Union from the EMA Committee for Orphan Medical Products.

Assuming development efforts are successful for RiVax^®, we believe potential government procurement contract(s) could reach as much as $200 million. This potential procurement contract information is a forward-looking statement, and investors are urged not to place undue reliance on this statement. While we have determined this potential procurement contract value based on assumptions that we believe are reasonable, there are a number of factors that could cause our expectations to change or not be realized.

As a new chemical entity, an FDA approved RiVax^® vaccine has the potential to qualify for a biodefense Priority Review Voucher (“PRV”). Approved under the 21st Century Cures Act in late 2016, the biodefense PRV is awarded upon approval as a medical countermeasure when the active ingredient(s) have not been otherwise approved for use in any context. PRVs are transferable and can be sold, with sales in recent years ~~varying from between $125 million to $350~~in excess of $100 million. When redeemed, PRVs entitle the user to an accelerated review period of nine months, saving a median of seven months review time as calculated in 2009. However, FDA must be advised 90 days in advance of the use of the PRV and the use of a PRV is associated with an additional user fee ($~~2.7~~2.2 million ~~in 2017)~~for fiscal year 2020).

Ricin Toxin

Ricin toxin can be cheaply and easily produced, is stable over long periods of time, is toxic by several routes of exposure and thus has the potential to be used as a biological weapon against military and/or civilian targets. As a bioterrorism agent, ricin could be disseminated as an aerosol, by injection, or as a food supply contaminant. The potential use of ricin toxin as a biological weapon of mass destruction has been highlighted in a Federal Bureau of Investigation Bioterror report released in November 2007 titledTerrorism 2002-2005,, which states that “Ricin and the bacterial agent anthrax are emerging as the most prevalent agents involved in WMD investigations” (http://www.fbi.gov/stats-services/publications/terrorism-2002-2005/terror02_05.pdf). In recent years, Al Qaeda in the Arabian Peninsula has threatened the use of ricin toxin to poison food and water supplies and in connection with explosive devices. Domestically, the threat from ricin remains a concern for security agencies. ~~As recently as~~In April 2013, letters addressed to the U.S. President, ~~of the United States,~~ a ~~U.S.~~ Senator and a judge tested positive for ricin. As recently as October 2018, an envelope addressed to President Trump was suspected to contain this potent and potentially lethal toxin, which was subsequently confirmed to contain pieces of castor beans used to make ricin.

The Centers for Disease Control and Prevention has classified ricin toxin as a Category B biological agent. Ricin works by first binding to glycoproteins found on the exterior of a cell, and then entering the cell and inhibiting protein synthesis leading to cell death. Once exposed to ricin toxin, there is no effective therapy available to reverse the course of the toxin. The recent ricin threat to government officials has heightened the awareness of this toxic threat. Currently, there is no FDA approved vaccine to protect against the possibility of ricin toxin being used in a terrorist attack, or its use as a weapon on the battlefield nor is there a known antidote for ricin toxin exposure.

~~OrbeShield~~^®~~– for Treating GI Acute Radiation Syndrome~~

~~OrbeShield~~^®is an oral immediate and delayed release formulation of the topically active corticosteroid BDP and is being developed for the treatment of GI ARS. Corticosteroids are a widely used class of anti-inflammatory drugs. BDP is a corticosteroid with predominantly topical activity that is approved for use in asthma, psoriasis and allergic rhinitis.

~~OrbeShield~~^®~~has demonstrated positive preclinical results in a canine GI ARS model which indicate that dogs treated with OrbeShield~~^®demonstrated statistically significant (p=0.04) improvement in survival with dosing at either two hours or 24 hours after exposure to lethal doses of total body irradiation (“TBI”) when compared to control dogs. OrbeShield^® ~~appears to significantly mitigate the damage to the GI epithelium caused by exposure to high doses of radiation using a well-established canine model of GI ARS.~~

The GI tract is highly sensitive to ionizing radiation and the destruction of epithelial tissue is one of the first effects of radiation exposure. The rapid loss of epithelial cells leads to inflammation and infection that are often the primary cause of death in acute radiation injury. This concept of GI damage also applies to the clinical setting of oncology, where high doses of radiation cannot be administered effectively to the abdomen because radiation is very toxic to the intestines. We are seeking to treat the same type of toxicity in our acute radiation enteritis clinical program with SGX201. As a result, we believe that OrbeShield^®has the potential to be a “dual use” compound, a desirable characteristic which is a specific priority for ARS and other medical countermeasure indications. The FDA has cleared the IND application for OrbeShield^® ~~for the mitigation of morbidity and mortality associated with GI ARS.~~

~~In September 2013, we received two government contracts from BARDA and NIAID for the advanced preclinical and manufacturing development of OrbeShield~~^®leading to FDA approval to treat GI ARS. The BARDA contract contained a two year base period with two contract options, exercisable by BARDA, for a total of five years and up to $26.3 million. The NIAID contract consisted of a one year base period and two contract options, exercisable by NIAID, for a total of three years and up to $6.4 million. We received a combined approximate $18 million in contract funding from both BARDA and NIAID which includes combined supplemental funding of $634,000, extending the programs through the first quarter of 2017. The NIAID contract was completed during the first quarter of 2017 along with the BARDA contract base period, with BARDA electing not to extend the current contract beyond the base period. We will continue to apply for additional government funding. Previously, development of OrbeShield^® had been largely supported by a $1 million NIH grant to our academic partner, the Fred Hutchinson Cancer Research Center. In July 2012, we received an SBIR grant from NIAID of approximately $600,000 to support further preclinical development of OrbeShield^® ~~for the treatment of acute GI ARS. The FDA has given OrbeShield~~^® ~~Orphan Drug designation and Fast Track designation for the prevention of death following a potentially lethal dose of total body irradiation during or after a radiation disaster.~~

~~Assuming development efforts are successful for OrbeShield~~^®, we believe potential government procurement contracts could reach as much as $450 million. This potential procurement contract information is a forward-looking statement. While we have determined this potential procurement contract value based on assumptions that we believe are reasonable, there are a number of factors that could cause our expectations to change or not be realized.

~~GI Acute Radiation Syndrome~~

ARS occurs after toxic radiation exposure and involves several organ systems, notably the bone marrow, the GI tract and later the lungs. In the event of a nuclear disaster or terrorist detonation of a nuclear bomb, casualties exposed to greater than 2 grays (“Gy”) of absorbed radiation are at high risk for development of clinically significant ARS. Exposure to high doses of radiation exceeding 10-12 Gy causes acute GI injury which can result in death. The GI tract is highly sensitive due to the continuous need for crypt stem cells and production of mucosal epithelium. The extent of injury to the bone marrow and the GI tract are the principal determinants of survival after exposure to TBI. Although the hematopoietic syndrome can be rescued by bone marrow transplantation or growth factor administration, there is no established treatment or preventive measure for the GI damage that occurs after high-dose radiation. As a result, we believe there is an urgent medical need for specific medical counter measures against the lethal pathophysiological manifestations of radiation-induced GI injury.

SGX943 – for Treating Emerging and/or Antibiotic-Resistant Infectious Diseases

SGX943 is an IDR, containing the same active ingredient as SGX942. Dusquetide is a fully synthetic, 5-amino acid peptide with high aqueous solubility and stability. Extensivein vivo preclinical studies have demonstrated enhanced clearance of bacterial infection with SGX943 administration. SGX943 has shown efficacy against both ~~gram-negative~~Gram-negative and ~~gram-positive~~Gram-positive bacterial infections in preclinical models, independent of whether the bacteria is antibiotic-resistant or antibiotic-sensitive.

The innate immune system is responsible for rapid and non-specific responses to combat bacterial infection. Augmenting these responses represents an alternative approach to treating bacterial infections. In animal models, IDRs are efficacious against both antibiotic-sensitive and antibiotic-resistant infections, both ~~gram-positive~~Gram-positive and ~~gram-negative~~Gram-negative bacteria, and are active irrespective of whether the bacteria occupies a primarily extracellular or intracellular niche. IDRs are also effective as stand-alone agents or in conjunction with antibiotics. An IDR for the treatment of serious bacterial infections encompasses a number of clinical advantages including:

●

Treatment when antibiotics are contraindicated, such as:

before the infectious organism and/or its antibiotic susceptibility is known; or

in at-risk populations prior to infection.

●

An ability to be used as an additive, complementary treatment with antibiotics, thereby:

enhancing efficacy of sub-optimal antibiotic regimens (e.g., partially antibiotic-resistant infections);

enhancing clearance of infection, thereby minimizing the generation of antibiotic resistance (e.g., in treating melioidosis); and

reducing the required antibiotic dose, again potentially minimizing the generation of antibiotic resistance.

●

An ability to modulate the deleterious consequences of inflammation in response to the infection, including the inflammation caused by antibiotic-driven bacterial lysis; and

●

Being unlikely to generate bacterial resistance since the IDR acts on the host, and not the pathogen.

Importantly, systemic inflammation and multi-organ failure is the ultimate common outcome of not only emerging and/or antibiotic-resistant infectious diseases, but also of most biothreat agents (e.g.,Burkholderia pseudomallei), indicating that dusquetide would be applicable not only to antibiotic-resistant infection, but also to biothreat agents, especially where the pathogen is not known and/or has been engineered for enhanced antibiotic resistance.

In May 2019, we were awarded a DTRA subcontract of approximately $600,000 over three years to participate in a biodefense contract for the development of medical countermeasures against bacterial threat agents. As of June 30, 2020, there was negligible revenue earned or expense incurred related to the DTRA subcontract.

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses, and related disclosure of contingent assets and liabilities. We evaluate these estimates and judgments on an on-going basis.

Revenue Recognition

Our revenues are primarily generated from government contracts and grants. The revenue from government contracts and grants is based upon subcontractor costs and internal costs incurred that are specifically covered by the contracts and grants, plus a facilities and administrative rate that provides funding for overhead expenses and management fees. These revenues are recognized when expenses have been incurred by subcontractors or when we incur reimbursable internal expenses that are related to the government contracts and grants.

Research and Development Costs

~~Accounting for Warrants~~

~~We considered FASB ASC 815,~~~~Evaluating Whether an Instrument is Considered Indexed to an Entity’s Own Stock~~, which provides guidance for determining whether an equity-linked financial instrument (or embedded feature) issued by an entity is indexed to the entity’s stock and, therefore, qualifying for the first part of the scope exception in paragraph 815-10-15. We evaluated the provisions and determined that warrants issued in connection with our June 2013 registered public offering contain provisions that protect holders from a decline in the issue price of our common stock (or “down-round” provisions) and contain net settlement provisions. Consequently, these warrants were recognized as liabilities at their fair value on the date of grant and remeasured at fair value on each reporting date.

~~Share-Based Compensation~~

Stock options are issued with an exercise price equal to the market price on the date of grant. Stock options issued to directors upon re-election vest quarterly for a period of one year (new director issuances are fully vested upon issuance). Stock options issued to employees generally vest 25% on the grant date, then 25% each subsequent year for a period of three years. Stock options vest over each three-month period from the date of issuance to the end of the three year period. These options have a ten year life for as long as the individuals remain employees or directors. In general, when an employee or director terminates their position the options will expire within three months, unless otherwise extended by the Board.

From time to time, we issue restricted shares of our common stock to vendors and consultants as compensation for services performed. Typically these instruments vest upon issuance and therefore the entire share-based compensation expense is recognized upon issuance to the vendors and/or consultants.

~~Share-based compensation expense for options, warrants and shares of common stock granted to non-employees has been determined in accordance with FASB ASC 505-50,~~~~Equity-Based Payments to Non-Employees~~, and represents the fair value of the consideration received, or the fair value of the equity instruments issued, whichever may be more reliably measured. For options that vest over future periods, the fair value of options granted to non-employees is amortized as the options vest. The fair value is remeasured each reporting period until performance is complete.

The fair value of each option grant made during 2017 and 2016 was estimated on the date of each grant using the Black-Scholes option pricing model and amortized ratably over the option vesting periods, which approximates the service period.

~~Income Taxes~~

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. A valuation allowance is established when it is more likely than not that all or a portion of a deferred tax asset will not be realized. A review of all available positive and negative evidence is considered, including the Company’s current and past performance, the market environment in which the Company operates, the utilization of past tax credits, and the length of carryback and carryforward periods. Deferred tax assets and liabilities are measured utilizing tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. No current or deferred income taxes have been provided through September 30, 2017 due to the net operating losses incurred by the Company since its inception. The Company recognizes accrued interest and penalties associated with uncertain tax positions, if any, as part of income tax expense. There were no tax related interest and penalties recorded for 2017 and 2016. Additionally, the Company has not recorded an asset for unrecognized tax benefits or a liability for uncertain tax positions at September 30, 2017 and December 31, 2016.

~~Earnings Per Share~~

Use of Estimates and Assumptions

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions such as the fair value of warrants and stock options and ~~recovery of~~ the useful life of intangibles that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates.

Material Changes in Results of Operations

Three and ~~Nine~~Six Months Ended ~~September~~June 30, ~~2017~~2020 Compared to ~~September~~June 30, ~~2016~~2019

For the three months ended ~~September~~June 30, ~~2017,~~2020, we had a net loss of ~~$963,094~~$2,776,763 as compared to a net loss of $1,673,217 for the same period in the prior year, representing a decrease in the net loss of $710,123 or 42%. For the nine months ended September 30, 2017, we had a net loss of $5,008,129 as compared to a net loss of $2,915,424$2,123,521 for the same period in the prior year, representing an increase in the net loss of ~~$2,092,705~~$653,242 or ~~72%~~31%. ~~Included~~This increase in net loss was primarily the result of increased research and development spending primarily attributable to higher clinical trial site and patient fees.

For the three months ended ~~September~~June 30, ~~2017,~~2020, we had revenues of ~~$1,822,066~~$505,288 as compared to ~~$2,959,254~~$1,544,964 for the same period in the prior year, representing a decrease of ~~$1,137,188~~$1,039,676 or ~~38%~~67%. For the ~~nine~~six months ended ~~September~~June 30, ~~2017,~~2020, we had revenues of ~~$4,143,921~~$1,429,842 as compared to ~~$8,750,291~~$2,689,752 for the same period in the prior year, representing a decrease of ~~$4,606,370~~$1,259,910 or ~~53%~~47%. The decrease in revenues was a result of the completion of the NIAID contract during the first quarter of 2017, along with the BARDA contract base period, with BARDA electing not to extend the current contract beyond the base period. This was partially offset by an increase in grant revenue for the three months ended September 30, 2017.

We also incurred costs related to those revenues for the three months ended ~~September~~June 30, ~~2017~~2020 and ~~2016~~2019 of ~~$1,474,151~~$363,339 and ~~$2,630,046,~~$1,086,814, respectively, representing a decrease of ~~$1,155,895,~~$723,475 or ~~44%~~67%. ~~For~~We also incurred cost related to those revenues for the ~~nine~~six months ended ~~September~~June 30, ~~2017, costs related to revenues were $3,238,633 as compared to $7,204,920 for the same period in the prior year,~~2020 and 2019 of $1,192,844 and $2,014,738, respectively, representing a decrease of ~~$3,966,287~~$821,894 or ~~55%~~41%. ~~The decrease in costs was primarily the result of the decrease in revenues from the completion of the NIAID and BARDA contracts.~~

Research and development expense - milestone expense was $5,000,000 for the six months ended June 30, 2020. The expense was due to the issuance of 1,956,182 shares of common stock to Hy Biopharma during the three months ended March 31, 2020 following the achievement of a ~~decrease~~milestone under the asset purchase agreement, specifically, the Phase 3 clinical trial of ~~$203,298 or 8%.

Interest income, net for the three months ended ~~September~~June 30, 2017 is primarily related to an increase in professional consulting fees. The decrease in general and administrative expenses for the nine months ended September 30, 2017 is primarily related to a decrease in our compensation expenses, including stock option expense.

~~Other income (expense) for the three months ended September 30, 2017~~2020 was ~~$6,529~~$2,017 as compared ~~$(174,400)~~to $39,851 for the same period in ~~2016, representing an increase in other income of $180,929 or 104%.

As of ~~September~~June 30, ~~2017,~~2020, we had working capital of ~~$3,047,007~~$5,992,411 as compared to working capital of ~~$7,243,918~~$1,181,249 as of December 31, ~~2016,~~2019, representing ~~a decrease~~an increase of ~~$4,196,911~~$4,811,162 or ~~58%~~407%. The ~~decrease~~increase in cash and ~~cash equivalents and~~ working capital iswas primarily related to ~~expenditures to support~~ the ~~pivotal Phase 3 clinical trial~~management of ~~SGX301 for~~our expenses, and proceeds received from the ~~treatment of CTCL and expenditures incurred in the preparation and initiation~~increased use of the ~~Phase 3 clinical trial of SGX942 for~~At Market Issuance Sales Agreement (“FBR Sales Agreement”) with B. Riley FBR, Inc. and the ~~treatment of oral mucositis in head and neck cancer.~~warrant exercises completed during the six months ended June 30, 2020.

Based on our current rate of cash outflows, cash on hand, proceeds from government contract and grant programs and proceeds available from the ~~equity line with Lincoln Park, proceeds remaining from the At-the-Market sale of shares of our common stock with~~ FBR ~~and proceeds from the State of New Jersey Technology Business Tax Certificate Transfer Program,~~Sales Agreement, management believes that its current cash will be sufficient to meet the anticipated cash needs for working capital and capital expenditures for at least the next twelve ~~months.~~months from issuance of the financial statements.

Our plans with respect to our liquidity management include, but are not limited to, the following:

●

We have up to ~~$20.6~~$1.54 million in active government contract ~~and grant~~ funding still available as of June 30, 2020 to support our associated research programs through ~~2017~~2020 and beyond, provided the federal agencies exercise all options and do not elect to terminate the contracts ~~or grants~~ for convenience. We plan to submit additional contract and grant applications for further support of our programs with various funding ~~agencies;~~agencies.


	●	We have continued to use equity instruments to provide a portion of the compensation due to vendors and collaboration partners and expect to continue to do so for the foreseeable ~~future;~~future.

●

We will continue to pursue ~~Net Operating Loss (“NOL”)~~net operating loss sales in the state of New Jersey pursuant to its Technology Business Tax Certificate Transfer ~~Program. We expect to receive $416,809 in net proceeds in 2017 from the sale of the NOL. We expect to participate in the program during 2018 and beyond as long as~~Program if the program is ~~available;~~available.


	●	We plan to pursue potential partnerships for pipeline ~~programs. However,~~programs; however, there can be no assurances that we can consummate such ~~transactions;~~transactions.


	●	We have ~~$10.2~~up to $1.5 million ~~available~~remaining from ~~an equity facility expiring in March 2019;~~the FBR Sales Agreement as of August 10, 2020 under the prospectus supplement updated April 10, 2020.


	●	We have ~~$4.3 million remaining~~been granted a Paycheck Protection Program Loan through the financial stimulus packages afforded by both the federal and state governments based on the current outbreak of SARS-CoV-2, the pathogen responsible for COVID-19. We were granted a total of $417,830 from JPMorgan Chase Bank, N.A. to fund our payroll costs and other expenses allowed by the ~~ATM agreement with FBR;~~program. We will continue to explore and evaluate additional funding options through financial stimulus packages afforded by both the federal and state governments based on the current outbreak of SARS-CoV-2, the pathogen responsible for COVID-19 as they become available.

●

We may seek additional capital in the private and/or public equity markets, pursue government contracts and grants as well as business development activities, to continue our operations, respond to competitive pressures, develop new products and services, and to support new strategic partnerships. We are currently evaluating additional equity/debt financing opportunities on an ongoing basis and may execute them when appropriate. However, there can be no assurances that we can consummate such a transaction, or consummate a transaction at favorable pricing.

Expenditures

Under our budget and based upon our existing product development agreements and license agreements pursuant to letters of intent and option agreements, we expect our total research and development expenditures for the next 12 months to be approximately ~~$10.5~~$6.5 million before any contract or grant reimbursements, of which ~~$7.0~~$5.4 million relates to the Specialized BioTherapeutics business and ~~$3.5~~$1.1 million relates to the ~~Vaccines/BioDefense~~Public Health Solutions business. We anticipate contract and grant ~~revenues~~reimbursements in the next 12 months of approximately ~~$5.5~~$1.4 million to offset research and development expenses ofin both the ~~Vaccines/BioDefense~~Specialized BioTherapeutics and the Public Health Solutions business ~~segment.~~segments.

Contractual Obligations

We have licensing fee commitments of approximately ~~$425,000~~$450,000 as of ~~September~~June 30, ~~2017 relating to~~2020 for several licensing agreements with entities, consultants and universities. Additionally, we have collaboration and license agreements, which upon clinical or commercialization success may require the payment of milestones of up to $7.9 million and/or royalties up to 6% of net sales of covered products, if and when achieved. However, there can be no assurance that clinical or commercialization success will occur. ~~As of September 30, 2017, no milestone or royalty payments have been paid or accrued.~~

~~In December 2014, we entered into~~We currently lease approximately 6,200 square feet of office space at 29 Emmons Drive, Suite B-10 in Princeton, New Jersey pursuant to a lease ~~agreement through May 31, 2018 for existing and expanded office space. The rent for the first 12 months~~that was approximately $12,300 per month, or approximately $20.85 per square foot. This rent increased to approximately $12,375 per month, or approximately $20.95 per square foot, for the next 12 months, and thereafter to approximately $12,460 per month, or approximately $21.13 per square foot for the remainder of the lease. Inamended in October 2017 and expires in October 2020. Pursuant to an amendment executed on July 7, 2020, the lease ~~was amended through~~has been extended to October ~~2020.~~2022. The current rent for the first 12 months will be approximately $11,367 per month, or approximately $22.00 per square foot. The rent will increase to approximately $11,625 per month, or approximately $22.50 per square foot, for the next 12 months and increase to approximatelyof $11,883 per month, or approximately $23.00 per square foot ~~for~~will be reduced to $21.50 per square foot, making the ~~remainder of the lease.~~monthly payment $10,850 starting in November 2020. Our office space is sufficient to satisfy our current needs.

On September 3, 2014, we entered into an asset purchase agreement with Hy Biopharma ~~Inc. (“Hy Biopharma”)~~ pursuant to which we acquired certain intangible assets, properties and rights of Hy Biopharma related to the development of Hy BioPharma’s synthetic hypericin product. As consideration for the assets acquired, we initially paid $275,000 in cash and issued 184,912 shares of common stock with a fair value based upon our stock price on the date of grant of $3,750,000. These amounts were charged to research and development expense during the third quarter of 2014 as the assets will be used in our research and development activities and do not have alternative future use pursuant to generally accepted accounting principles in the ~~United States.~~ U.S.

On March 20, 2020, we filed a prospectus supplement covering the offer and sale of up to 1,956,182 shares of our common stock which were issued to Hy Biopharma. We were required to issue the shares to Hy Biopharma as payment following the achievement of a milestone under the asset purchase agreement, specifically, the Phase 3 clinical trial of SGX301 being successful in the treatment of CTCL. The number of shares of our common stock issued to Hy Biopharma was calculated using an effective price of $2.56 per share, based upon a formula set forth in the asset purchase agreement.

Provided ~~all future~~the final success-oriented ~~milestones are~~milestone is attained, we will be required to make ~~payments~~a payment of up to ~~$10.0~~$5.0 million, if and when achieved. ~~Payments~~The potential future payment will be payable in ~~restricted securities of the Company~~our common stock not to exceed 19.9% ~~ownership~~ of our outstanding stock. ~~As of September 30, 2017, no milestone payments have been made or accrued.~~

In ~~February 2007,~~January 2020, our Board of Directors authorized an amendment to Dr. Schaber’s employment agreement to increase the ~~issuance~~number of ~~5,000~~ shares of ~~our~~ common stock from 5,000 to 500,000, issuable to Dr. Schaber immediately prior to the completion of a transaction, or series or a combination of related transactions, negotiated by our Board of Directors whereby, directly or indirectly, a majority of our capital stock or a majority of our assets are transferred from us and/or our stockholders to a third party. ~~Dr. Schaber’s amended employment agreement includes our obligation to issue such shares if such event occurs.~~

As a result of ~~these~~the above agreements, we have future contractual obligations ~~over the next five years~~ as follows:

CARES Act Loan

On April 13, 2020, we were advised that one of our principal banks, JPMorgan Chase Bank, N.A., had approved a $417,830 loan (the “Loan”) under the Paycheck Protection Program (“PPP”) pursuant to the Coronavirus Aid, Relief and Economic Security Act that was signed into law on March 27, 2020.

As a U.S. small business, we qualified for the PPP, which allows businesses and nonprofits with fewer than 500 employees to obtain loans of up to $10 million to incentivize companies to maintain their workers as they manage the business disruptions caused by the COVID-19 pandemic. The PPP provides for loans for amounts up to 2.5 times of the average monthly payroll expenses of the qualifying business. The PPP loan proceeds may be used for eligible purposes, including payroll, benefits, rent and utilities.

The Loan, has a term of two years, is unsecured, and is guaranteed by the Small Business Administration. The Loan bears interest at a fixed rate of 0.98% per annum, with the first six months of interest and principal deferred. Some or all of the Loan may be forgiven if at least 75% of the Loan proceeds are used by us to cover payroll costs, including benefits and if we maintain our employment and compensation within certain parameters during the eight-week or twenty-four-week period following the Loan origination date and comply with other relevant conditions. We intend to use the proceeds for purposes consistent with the PPP and expect to meet the conditions for forgiveness of the Loan.

Contingencies

Based on the current outbreak of SARS-CoV-2, the pathogen responsible for COVID-19, which has already had an impact on financial markets, there could be additional repercussions in our operating business, including but not limited to, the sourcing of materials for product candidates, manufacture of supplies for preclinical and/or clinical studies, delays in clinical operations, which may include the availability or the continued availability of patients for trials due to such things as quarantines, conduct of patient monitoring and clinical trial data retrieval at investigational study sites.

The future impact of the outbreak is highly uncertain and cannot be predicted, and we cannot provide any assurance that the outbreak will not have a material adverse impact on our operations or future results or filings with regulatory health authorities. The extent of the impact, if any, we will depend on future developments, including actions taken to contain the coronavirus.

ITEM 3 -– QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S. interest rates, particularly because the majority of our investments are in short-term marketable ~~securities.~~securities, in addition to the foreign exchange rate fluctuations related to our foreign currency transactions. We do not have any derivative financial instruments. Due to the nature of our short-term investments, we believe that we are not subject to any material market risk exposure. ~~We do not have any foreign currency or other derivative financial instruments.~~

ITEM 4 -– CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are ~~the Company’s~~our controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the U.S. Securities and Exchange Commission. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Our management recognizes that any controls and procedures, no matter how well designed and operated, can only provide reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the possible controls and procedures.

Our management has evaluated, with the participation of our principal executive officer and principal financial officer, the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based upon that evaluation, our management, including our principal executive officer and principal financial officer, has concluded that, as of the end of the period covered by this report, ~~the Company’s~~our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Controls

There was no change in our internal control over financial reporting identified in connection with the evaluation of such internal controls that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, ~~the Company’s~~our internal control over financial reporting.

We have not experienced any material impact to our internal controls over financial reporting despite the fact that our employees are working remotely due to the COVID-19 pandemic. We are continually monitoring and assessing the COVID-19 situation on our internal controls to minimize the impact on their design and operating effectiveness.

PART II –- OTHER INFORMATION.

ITEM 1 – LEGAL PROCEEDINGS

On July 1, 2020, the Company filed a demand for arbitration against Emergent BioSolutions, Inc. (“EBS”); Emergent Product Development Gaithersburg, Inc. (“EPDG”); and Emergent Manufacturing Operations Baltimore LLC (“EMOB” and together with EBS and EPDG, “Emergent”) with the American Arbitration Association in Mercer County, New Jersey in which the Company has alleged that (a) EPDG breached the EPDG Subcontract (defined in the following paragraph), the EPDG Quality Agreement (defined in the following paragraph), an express warranty, a warranty of merchantability, and a warranty of fitness for a particular purpose, (b) EMOB breached the EMOB Quality Agreement (defined in the following paragraph); (c) EPDG was unjustly enriched; (d) EPDG and EMOB were negligent in the performance of their work; and (e) EBS fraudulently induced the Company into entering into the contracts with EPDG and EMOB. Emergent has answered that demand for arbitration denying the allegations and asserting affirmative defenses.

After several months of negotiations and based on representations Emergent made related to its capabilities in developing upstream and downstream processes for vaccines and its designation as a Center for Innovation in Advanced Development and Manufacturing, in May 2015, the Company entered into a subcontract (the “EPDG Subcontract”) with EPDG, pursuant to which EPDG agreed to manufacture, and provide to the Company, RiVax^® bulk drug substance (“BDS”). In March 2017, the Company entered into a quality agreement (the “EPDG Quality Agreement”) with EPDG for the purpose of defining and allocating the quality-related responsibilities between the Company and EPDG with respect to the production of the RiVax^® BDS under the EPDG Subcontract.

After nearly three years of EPDG failing to meet the scope of work set forth in the EPDG Subcontract, Emergent recommended that both development and manufacturing work under the EPDG Subcontract be transferred to EMOB. On July 9, 2018, the Company entered into a quality agreement (the “EMOB Quality Agreement”) with EMOB, which agreement allocated various defined responsibilities between the Company and EMOB with respect to the manufacture, supply, and testing of the RiVax^® BDS. Under the EMOB Quality Agreement, EMOB assumed sole responsibility for, inter alia, (i) employee training; (ii) providing adequate and qualified personnel; (iii) notifying the Company of out-of-specification results within two (2) business days of identification of the out of-specification results; (iv) performing testing using agreed-to testing procedures, test methods, specifications, and required compendia requirements; (v) ensuring that EMOB-generated data was accurate, controlled and safe from manipulation or loss; (vi) ensuring that the procedures, the state of automation and/or management controls were in place to assure data integrity; (vii) apprising the Company of any significant changes to analytical methodology for intermediaries, in-process or final product; and (viii) assuring that samples were stored in appropriate, continuously monitored conditions.

On January 8, 2020, EMOB informed the Company (a) of the existence of a questionable test result that could result in a determination that the RiVax^® BDS manufactured, tested and released by EMOB was out-of-specification and should never have been released by Emergent (b) that the validity of “initial release” test results for such BDS was faulty because Emergent used an improper test method. The Company immediately suspended the Phase 1c trial to evaluate RiVax^® in healthy adults, ending both further enrollment and further dosing. Emergent conducted an internal review of this deviation and found multiple internal failures including an “Inadequate analytical method transfer process,” an “Inability to comply with standard operating procedures around method transfer and data review,” and an “Inability to comply with test method procedures,” The Company quickly initiated a “for-cause” audit of the Emergent facility and confirmed the failures Emergent identified and admitted to in its own internal investigation.

The Company is seeking to recover damages in excess of $19 million from Emergent. While the Company intends to vigorously pursue this arbitration, the Company cannot offer any assurances that it will recover any damages from Emergent.

ITEM 1A – RISK FACTORS

Our business faces significant risks. These risks include those disclosed in ~~Part I,~~ Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, ~~2016.~~2019. If any of the events or circumstances described in the referenced risks actually occur, our business, financial condition or results of operations could be materially adversely affected and such events or circumstances could cause our actual results to differ materially from the results contemplated by the “forward-looking” statements contained in this report. These risks should be read in conjunction with the other information set forth in this Quarterly Report as well as in our Annual Report on Form 10-K for the fiscal year ended December 31, ~~2016~~2019 and in our periodic reports on Form 10-Q and Form 8-K. Additional risks not presently known to us or other factors not perceived by us to present significant risks to our business at this time also may impair our business, financial condition and results of operations. We do not undertake to update any of the “forward-looking” statements or to announce the results of any revisions to these “forward-looking” statements, except as required by law.

ITEM 25 – ~~UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS~~OTHER INFORMATION

~~In July 2017, we sold 40,000 shares~~As previously reported, on May 13, 2020, the Company’s Board of ~~common stock~~Directors approved an amendment (the “Amendment”) to ~~Lincoln Park Capital Fund, LLC (“Lincoln Park”~~the Company’s Amended and Restated By-laws (the “Bylaws”) ~~for an aggregate price of $92,830, and issued~~ to ~~Lincoln Park 387 additional shares of common stock~~add forum selection provisions as a ~~commitment fee. Such securities were issued pursuant to an exemption provided by~~new Section ~~4(a)(2)~~10.7 of the ~~Securities Act. Lincoln Park represented to us~~Bylaws.

Under new Section 10.7, unless the Company consents otherwise, the Court of Chancery of the State of Delaware will be the exclusive forum for any litigation consisting of derivative actions, actions asserting a breach of fiduciary duty, actions under the Delaware General Corporation Law and actions asserting claims under the internal affairs doctrine.

Further, Section 10.7 provides that, ~~it is an “accredited investor” as defined in Rule 501(a)~~unless the Company consents otherwise, the federal district courts of ~~Regulation D promulgated~~the United States of America will be the exclusive forum for any litigation asserting a claim under the Securities ~~Act; is knowledgeable, sophisticated~~Act of 1933, as amended. In addition, Section 10.7 stipulates that any person or entity purchasing or otherwise acquiring or holding any interest in shares of capital stock of the Company will be deemed to have notice of and ~~experienced in making investment decisions~~consented to the provisions of ~~this kind and received adequate information about us or had adequate access, including through Lincoln Park’s business relationship with us, to information about us.~~Section 10.7.

~~SIGNATURES~~

~~In accordance with the requirements~~Section 27 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the ~~Registrant has duly caused this report~~Exchange Act or the rules and regulations thereunder. Accordingly, the exclusive forum provisions in the Bylaws do not apply to claims arising under the Exchange Act. The forum selection provisions, however, are intended to apply to the fullest extent permitted by law, including to actions or claims arising under the Securities Act. However, it is possible that a court could find the forum selection provisions to be ~~signed on its behalf~~inapplicable or unenforceable with respect to actions or claims arising under the Securities Act. Even if a court accepts that the forum selection provisions apply to actions or claims arising under the Securities Act, the Company’s stockholders shall not be deemed to have waived compliance with the federal securities laws and the rules and regulations thereunder.

The Amendment was intended by the ~~undersigned, thereunto duly authorized.~~Board of Directors to update and modernize the Company’s by-laws. The Board of Directors believes, among other things, that adoption of the forum selection provisions should benefit the Company and its stockholders by allowing the Company to reduce litigation costs in the event of the identified litigation by avoiding litigating similar or identical claims in multiple jurisdictions. In addition, the forum selection provisions would allow the Company to litigate matters relating to Delaware corporate law and the internal affairs of the Company in Delaware courts, which have particular expertise in the subject matters.

The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Amendment, a copy of which was filed as Exhibit 3.1 to the Quarterly Report on Form 10-Q for the quarter ended March 31, 2020 and is incorporated herein by reference.
