Rhea-AI Summary
Hepion Pharmaceuticals announces positive results from a research study showing that their lead drug candidate, rencofilstat, significantly suppressed tumor growth in mice infected with the hepatitis C virus. The drug demonstrated preventative and regressive anti-tumor activity, outperforming other anti-HCV agents such as sofosbuvir and velpatasvir. Rencofilstat's pleiotropic effects make it a promising treatment for liver cancer arising from HCV infection.
Positive
  • Rencofilstat prevented the growth of liver tumors in mice infected with HCV
  • Daily rencofilstat treatment completely prevented HCC development
  • Rencofilstat was able to completely regress small cancerous nodules
  • Rencofilstat treatment resulted in significantly decreased numbers and sizes of tumors
  • Rencofilstat's anti-tumor activity was superior to sofosbuvir and velpatasvir
Negative
  • None.

- Rencofilstat, but not sofosbuvir or velpatasvir, significantly suppressed tumor growth -

EDISON, N.J., Oct. 25, 2023 (GLOBE NEWSWIRE) -- Hepion Pharmaceuticals, Inc. (NASDAQ:HEPA), a clinical stage biopharmaceutical company focused on Artificial Intelligence (“AI”)-driven therapeutic drug development for the treatment of non-alcoholic steatohepatitis (“NASH”), fibrotic diseases, hepatocellular carcinoma (“HCC”), and other chronic diseases, today announced the publication of a new research study in mice, where Hepion’s lead drug candidate, rencofilstat, prevented the growth of liver tumors that occurred as a result of chronic infection with the human hepatitis C virus (“HCV”).

The study was published in the peer-reviewed, open access scientific journal, Viruses, and was conducted by Drs. Winston Stauffer, Philippe Gallay, and colleagues at The Scripps Research Institute (La Jolla, California). Mice were infected with HCV, which caused the development of small liver nodules at around 12 weeks post-infection that progressed to very large tumors by 24 weeks post-infection. Daily rencofilstat treatment was initiated at week 0 or later time points:

  • When initiated at week 0, rencofilstat treatment completely prevented HCC development measured at week 30 likely because the drug also blocked HCV infection and therefore eliminated a key driver of HCC development;
  • When initiated at week 12, when tumors were in a small nodular stage, rencofilstat treatment similarly resulted in no visible nodules or tumors at week 30, suggesting that rencofilstat was able to completely regress small cancerous nodules; and
  • When initiated at week 16, when livers contained many small-to-medium-sized nodules and tumors, rencofilstat treatment resulted in significantly decreased numbers and sizes of tumors (“tumor burden”) measured at week 30, which also indicated preventative or regressive anti-tumor activity.

To investigate whether some of rencofilstat’s anti-HCC effects occurred independent of its anti-HCV activity, rencofilstat was compared to the anti-HCV agents sofosbuvir and velpatasvir, which belong to the recently developed direct-acting class of HCV drugs representing billions of dollars in annual sales.

Sofosbuvir, velpatasvir and rencofilstat treatments initiated at week 16 all eliminated HCV infection. However, only rencofilstat decreased tumors when measured at week 30. Sofosbuvir and velpatasvir-treated mice developed the same large tumor burden as mice that received no drug treatment, whereas the tumor burden of rencofilstat-treated mice was 80% lower.

“These results highlight one of rencofilstat’s greatest strengths, which is the ability to exert pleiotropic effects that can be harnessed to treat multiple diseases,” said Dr. Daren Ure, Hepion’s Chief Scientific Officer. “This contrasts with highly selective drugs that target single mechanisms, such as the currently available anti-HCV drugs that do not effectively treat liver cancer arising from HCV infection. We believe that rencofilstat is the ideal treatment for this kind of cancer as it stops viral replication and suppresses cancer through separate and complementary pathways.”

Dr. Robert Foster, Hepion’s CEO, added “The antiviral, anti-cancer, and antifibrotic activities of rencofilstat address many of the most deadly and prevalent diseases affecting people today. Not only could rencofilstat have an enormous impact on human health, but the investment growth opportunities associated with treating these high-need, global-scale diseases are equally large.”

Hepion recently announced a new mechanism by which rencofilstat exerts anti-cancer activity in liver cancer and the drug’s anti-cancer activity in numerous cell lines representing 86% of cancer types.

About Hepion Pharmaceuticals

The Company's lead drug candidate, rencofilstat, is a potent inhibitor of cyclophilins, which are involved in many disease processes. Rencofilstat has been shown to reduce liver fibrosis and hepatocellular carcinoma tumor burden in experimental disease models and is currently in Phase 2 clinical development for the treatment of NASH. In November 2021, the U.S. Food and Drug Administration (“FDA”) granted Fast Track designation for rencofilstat for the treatment of NASH. That was followed in June 2022 by the FDA’s granting of Orphan Drug designation to rencofilstat for the treatment of HCC.

Hepion has created a proprietary Artificial Intelligence deep machine learning (“AI/ML”) platform designed to better understand disease processes and identify patients that are rencofilstat responders. This AI/ML has the potential to shorten development timelines and increase the observable differences between placebo and treatment groups. In addition, Hepion’s AI/ML can be used to drive its ongoing NASH and HCC clinical development programs and identify other potential therapeutic indications for cyclophilin inhibition with rencofilstat.
