Termination of ATM Prospectus Supplement

On February 6, 2023, Processa Pharmaceuticals, Inc. (the “Company”) terminated the prospectus supplement (the “ATM Prospectus Supplement”) related to the Company’s common stock, par value $0.0001 per share (the “ATM Shares”). On February 5, 2023, the Company delivered written notice to Oppenheimer & Co. Inc. (the “Sales Agent”) of such termination, issuable pursuant to the Equity Distribution Agreement, dated August 20, 2021, by and between the Company and the Sales Agent (the “Equity Distribution Agreement”). The Company will suspend the sale of the ATM Shares pursuant to the Equity Distribution Agreement, unless and until a new prospectus supplement is filed. Other than the termination of the ATM Prospectus Supplement and suspension of the sale of the ATM Shares under the Equity Distribution Agreement, the Equity Distribution Agreement remains in full force and effect.

A copy of the Equity Distribution Agreement was filed as Exhibit 1.1 to the Company’s Form 10-K for the fiscal year ended December 31, 2021 filed with the Securities and Exchange Commission on March 30, 2022.

Focus on Next Generation Chemotherapy/Suspension of Further Enrollment in PCS499 Trials

Consistent with the shift in priority, including the allocation of resources to Next Generation Chemotherapy drugs, the Company intends to suspend further enrollment in the PCS499 trial for ulcerative Necrobiosis Lipoidica. The Company has begun and will continue to meet with potential licensing partners, as well as consider other options to monetize PCS12852 and PCS499. As previously reported, the clinical study findings for PCS12852 were positive in gastroparesis patients. There were no safety concerns during the conduct of either study, and the Company continues to believe that PCS499 could be effective in treating other ulcers, including less rare indications for PCS499 such as chronic venous ulcers and intermittent claudication.
