ContraVir Pharmaceuticals Announces National Institutes of Health Funded Study on Antiviral Activity of CRV431
“We are pleased to work with KMT through the preclinical services program supported by the NIH,” said Dr.
CRV431 is a non-immunosuppressive analog of cyclosporine A (CsA) whose primary biochemical action is inhibition of cyclophilin isomerase activity, playing a key role in protein folding. Other viruses, such as HIV-1 and HCV, similarly use cyclophilin for their replication. CRV431 shows potential in experimental models to complement current hepatitis B treatments by reducing multiple markers of infection including HBV DNA, HBsAg, HBx, HBeAg, and HBV uptake by cells. Studies have also demonstrated that CRV431 possesses anti-fibrotic activity which may further curb progression of liver disease in patients.
ContraVir is a biopharmaceutical company focused on the development and commercialization of targeted antiviral therapies with a specific focus on developing a potentially curative therapy for hepatitis B virus (HBV). The Company is developing two novel anti-HBV compounds with complementary mechanisms of action. TXL™ currently in Phase 2, is designed to deliver high intrahepatic concentrations of TFV, while minimizing off-target side-effects caused by high levels of circulating TFV. CRV431, the other anti-HBV compound, is a next-generation cyclophilin inhibitor with a unique structure that increases its potency and selective index against HBV. ContraVir is also developing Valnivudine™, an orally available nucleoside analogue prodrug; Valnivudine™ is currently in Phase 3 for the treatment of herpes zoster. In addition to direct antiviral activity, Phase 2 data suggest that Valnivudine™ has the potential to reduce the incidence of debilitating shingles-associated pain known as post-herpetic neuralgia (PHN).
