About CRV431
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. In pre-clinical studies, CRV431 has shown 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 reduces the progression of fibrosis in an animal model and also reduces both the number and size of liver tumors in a hepatocellular carcinoma (HCC) model.
About
ContraVir is a biopharmaceutical company focused on the development and commercialization of targeted therapies for liver disease arising from chronic hepatitis B, C and D virus (HBV, HVC, HDV) and non-alcoholic steatohepatitis (NASH). The company is developing two novel anti-HBV compounds with complementary mechanisms of action. TXL™, a direct acting antiviral (DAA) nucleotide analog lipid prodrug of tenofovir (TFV), is designed to deliver higher hepatic intracellular concentrations of the active tenofovir species (tenofovir diphosphate) while reducing concentrations of tenofovir outside the liver, causing fewer off-target toxicities and side-effects. CRV431, the other anti-HBV compound, is a host-targeting antiviral (HTA) next-generation cyclophilin inhibitor with a novel chemical structure that optimizes the selective index against HBV. In vitro and in vivo studies have thus far demonstrated that CRV431 reduces HBV DNA and other viral proteins, including surface antigen (HBsAg), while offering additional benefits such as reducing liver fibrosis and hepatocellular carcinoma tumor burden.
