Clemizole can yield high-level synergy with protease inhibitor class: Research

Eiger BioPharmaceuticals, Inc., a biotechnology company developing antiviral therapies, announced today the publication of research from the lab of Stanford scientist and Eiger Founder, Dr. Jeffrey Glenn, M.D., Ph.D. and colleagues entitled, "The Hepatitis C Virus (HCV) NS4B RNA Binding Inhibitor Clemizole is Highly Synergistic with HCV Protease Inhibitors".

"This work demonstrates that clemizole can yield high-level synergy with the protease inhibitor class," said David Cory, President and CEO of Eiger.  "Inclusion of clemizole in future anti-HCV cocktails represents an attractive paradigm for increasing virologic response rates and may minimize unwanted side effects and combat drug resistance to HCV protease inhibitors."

"Clemizole appears to be able to dramatically increase the in vitro efficacy of other agents such as the NS3 protease inhibitors in advanced clinical development," said Jeffrey Glenn, M.D., Ph.D., Founder of Eiger.  "The addition of clemizole to regimens may allow protease inhibitors to be used at lower doses, thereby maintaining the desired antiviral efficacy while avoiding the toxicities associated with the protease inhibitors such as severe rash and anemia.  Clemizole has the potential to be an ideal component of future anti-HCV cocktails."
