As disclosed in the notes to the consolidated financial statements included in the Company’s 2021 Form 10-K, the Company has been engaged in litigation with Platinum-Montaur Life Sciences LLC (“Platinum-Montaur”), an affiliate of Platinum Management (NY) LLC, Platinum Partners Value Arbitrage Fund L.P., Platinum Partners Capital Opportunity Fund, Platinum Partners Liquid Opportunity Master Fund L.P., Platinum Liquid Opportunity Management (NY) LLC, and Montsant Partners LLC (collectively, “Platinum”). In addition, the Company is engaged in ongoing litigation with our former President and Chief Executive Officer, Dr. Michael Goldberg. The Company has also been engaged in ongoing litigation with Capital Royalty Partners II L.P. (“CRG”). See Note 10.

On April 10, 2022, the Company entered into a Stock Exchange and Loan Agreement (the “Purchase Agreement”) with John K. Scott, Jr., the current Vice Chairman of our Board of Directors, pursuant to which Mr. Scott agreed to make a loan to the Company in the principal amount of up to $2.5 million, of which $1.5 million was funded on the closing date. Mr. Scott funded an additional $1.0 million on July 1, 2022. The outstanding balance of the loan, which is evidenced by a Secured Term Note (the “Bridge Note”), bears interest at a rate of 8% per annum, with payments of interest only to be made monthly over a period of two years. All outstanding principal and accrued and unpaid interest under the Bridge Note is due and payable on the second anniversary of the Purchase Agreement. The Company’s obligations under the Bridge Note are secured by a first priority security interest in all of the Company’s assets and personal property pursuant to a Security Agreement. See Notes 8 and 16.

Beginning August 4, 2022 through August 17, 2022, the Company is offering its stockholders and certain warrant holders as of August 3, 2022 the right to purchase up to 35,000 units (“Units”) at a subscription price of $1,000 per Unit (the “Rights Offering”). Each Unit consists of one share of Series I Convertible Preferred Stock (“Series I Preferred Stock”) which is convertible into 1,538 shares of Common Stock and warrants to purchase an additional 1,538 shares of our Common Stock. The Rights Offering may result in aggregate gross proceeds of up to $35.0 million to the Company. Certain participants in the Rights Offering have the ability to pay the subscription price for their Units by cancelling or exchanging their shares of Series D Redeemable Convertible Preferred Stock (“Series D Preferred Stock”), Series F Redeemable Convertible Preferred Stock (“Series F Preferred Stock”) and/or Series G Redeemable Preferred Stock (“Series G Preferred Stock”) and the Company’s indebtedness evidenced by the Bridge Note, instead of paying by check or wire transfer of funds. The fair market value of the shares of each series of preferred stock and the Bridge Note to be cancelled or exchanged in the Rights Offering has been determined by the Company’s Board of Directors based on an independent appraisal obtained by the Company. The total amount of cash proceeds received by the Company will be reduced to the extent any such series of preferred stock and/or the Bridge Note are exchanged or cancelled in the Rights Offering. Net proceeds after deducting fees and expenses related to the Rights Offering will be used to fund our pivotal Phase 3 clinical trial for rheumatoid arthritis (“RA”), obtaining regulatory approvals, working capital, and for general corporate purposes.

We do not believe there has been a significant impact to the Company’s clinical development and regulatory timelines resulting from the ongoing COVID-19 global pandemic. However, the COVID-19 outbreak delayed enrollment in our NAV3-32 clinical study in the United Kingdom (“UK”) due to national COVID-19-related shutdowns. In addition, the regulatory approval process in India was delayed by the impact of COVID-19 in that country.

The current conflict between Ukraine and Russia has created extreme volatility in the global capital markets and is expected to have further global economic consequences, including disruptions of the global supply chain and energy markets. Any such volatility and disruptions may have adverse consequences on us or the third parties who operate in Europe on whom we rely. If the equity and credit markets deteriorate, including as a result of political unrest or war, it may make any debt or equity financing more difficult to obtain, more costly or more dilutive.

The Company has experienced recurring net losses and has used significant cash to fund its operations. The Company has considerable discretion over the extent of development project expenditures and has the ability to curtail the related cash flows as needed. The Company also continues working to establish new sources of funding, including the Rights Offering that is currently underway, other potential equity investments, collaborations and additional grant funding that can augment the balance sheet. However, based on our current working capital and our projected cash burn, management believes that there is substantial doubt about the Company’s ability to continue as a going concern for a period of one year from the filing of this Quarterly Report on Form 10-Q.
