Hepion Pharmaceuticals Announces Further Adjournment of Annual Meeting of Stockholders

EDISON, N.J., July 22, 2022 - Hepion Pharmaceuticals, Inc. (NASDAQ:HEPA), a clinical mid-stage biopharmaceutical company focused on Artificial Intelligence (“AI”)-driven therapeutic drug development for the treatment of non-alcoholic steatohepatitis (“NASH”) and hepatocellular carcinoma (“HCC”), announced today that its 2022 annual meeting of stockholders (the “Annual Meeting”) has been further adjourned to Friday, August 5, 2022 at 9:00 a.m. Eastern Time with respect to Proposal 4 (Authorized Share Increase), as described in Hepion’s definitive proxy statement filed with the U.S. Securities and Exchange Commission (the “SEC”) on April 29, 2022 (the “Proxy Statement”).

The record date for determining stockholders entitled to vote at the adjourned Annual Meeting will remain the close of business on April 26, 2022.

During the current adjournment, Hepion will continue to solicit votes from its stockholders with respect to Proposal 4 set forth in the Proxy Statement.

At the time the Annual Meeting was further adjourned, proxies had been submitted by stockholders representing approximately 60% of the shares of Hepion’s common stock outstanding and entitled to vote, which constituted a quorum.

Proxies previously submitted with respect to the Annual Meeting will be voted on Proposal 4 at the adjourned Annual Meeting unless properly revoked, and stockholders who have previously submitted a proxy or otherwise voted need not take any action.

The Board of Hepion believes that the approval of Proposal 4 is in the best interests of the stockholders of Hepion because the availability of additional authorized shares of common stock is required for several reasons including, but not limited to, the additional flexibility to issue common stock for a variety of general corporate purposes as the Board may determine to be desirable including, without limitation, future financings, investment opportunities, acquisitions, or other distributions and stock splits (including splits effected through the declaration of stock dividends).

Hepion encourages all stockholders of record on April 26, 2022 who have not yet voted to do so by 11:59 p.m. Eastern Time on August 4, 2022.

About Hepion Pharmaceuticals

Hepion's lead drug candidate, rencofilstat, is a potent inhibitor of cyclophilins, which are involved in many disease processes. Rencofilstat is currently in clinical-phase development for the treatment of NASH, with the potential to play an important role in the overall treatment of liver disease - from triggering events through to end-stage disease. Rencofilstat has been shown to reduce liver fibrosis and hepatocellular carcinoma tumor burden in experimental models of NASH, and has demonstrated antiviral activities towards HBV, HCV, and HDV through several mechanisms, in nonclinical studies. In November 2021, the U.S. Food and Drug Administration (“FDA”) granted Fast Track designation for rencofilstat for the treatment of NASH. That was soon followed in December 2021 by the FDA’s acceptance of Hepion’s investigational new drug (IND) application for rencofilstat for the treatment of hepatocellular carcinoma (HCC). In June 2022, rencofilstat was granted Orphan Drug designation for the treatment of HCC.

Hepion has created a proprietary AI platform, called AI-POWR™, which stands for Artificial Intelligence - Precision Medicine; Omics (including genomics, proteomics, metabolomics, transcriptomics, and lipidomics); World database access; and Response and clinical outcomes. Hepion intends to use AI-POWR™ to help identify which NASH patients will best respond to rencofilstat, potentially shortening development timelines and increasing the delta between placebo and treatment groups. In addition to using AI-POWR™ to drive its ongoing NASH clinical development program, Hepion intends to use the platform to identify additional potential indications for rencofilstat to expand the company's footprint in the cyclophilin inhibition therapeutic space.
