ICAAC 2012: HCV Polymerase Inhibitor Sofosbuvir Appears Safe and Effective for HIV/HCV Coinfected People

HIV/altHCV coinfected people taking the experimental hepatitis C virus (HCV) polymerase inhibitor sofosbuvir (formerly GS-7977) experienced a rapid decline in HCV viral load similar to that seen in HIV negative patients, researchers reported this week at the 52nd Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC 2012) in San Francisco. Side effects were also similar, and there was no sign of interactions with antiretroviral drugs in this 14-day study
