Description: Sofosbuvir, also known as PSI-7977 and GS7977 (brand names Sovaldi and Virunon), is a drug used for hepatitis C virus (HCV) infection, with a high cure rate. It inhibits the RNA polymerase that the hepatitis C virus uses to replicate its RNA. It was discovered at Pharmasset and developed by Gilead Sciences. Sofosbuvir is a component of the first all-oral, interferon-free regimen approved for treating chronic Hepatitis C. In 2013, the FDA approved sofosbuvir in combination with ribavirin (RBV) for oral dual therapy of HCV genotypes 2 and 3, and for triple therapy with injected pegylated interferon (pegIFN) and RBV for treatment-naive patients with HCV genotypes 1 and 4.

Additional Information

Sofosbuvir treatment regimens last 12 weeks for genotypes 1, 2 and 4, compared to 24 weeks for treatment of genotype 3. The label further states that sofosbuvir in combination with ribavirin may be considered for patients infected with genotype 1 who are interferon-ineligible. Sofosbuvir will cost $84,000 for 12 weeks of treatment and $168,000 for the 24 weeks, which some patient advocates have criticized as unaffordable. Interferon-free therapy for treatment of hepatitis C eliminates the substantial side-effects associated with use of interferon. Up to half of hepatitis C patients cannot tolerate the use of interferon. (
