Part A: Drug Interaction Study of Sofosbuvir and Antiretroviral Therapy (ART) Combinations in HIV and Hepatitis C Virus (HCV) Co-infected Patients. Part B: Efficacy and Safety of Sofosbuvir for 12 Weeks in HIV/HCV Co-infected Patients.

25. september 2014 opdateret af: Gilead Sciences

Part A: Drug Interaction Study Between GS-7977 and Antiretroviral Therapy (ARV) Combinations of Efavirenz, Tenofovir and Emtricitabine; Efavirenz, Zidovudine and Lamivudine; Atazanavir/Ritonavir, Tenofovir and Emtricitabine; Darunavir/Ritonavir, Tenofovir and Emtricitabine; Raltegravir, Tenofovir and Emtricitabine in Human Immunodeficiency Virus and Hepatitis C Virus (HIV/HCV) Co-infected Patients. Part B: A Phase 2, Open-Label Study to Investigate the Efficacy and Safety of GS-7977 With Peginterferon Alfa 2a and Ribavirin for 12 Weeks in Treatment-Naïve HIV/HCV Co-infected Patients.

This study consists of 2 parts, Part A and Part B. Part A, the Phase 1 drug interaction/early viral kinetic study, will evaluate the effect of selected antiretroviral therapies on the safety, viral kinetics, and pharmacokinetics of sofosbuvir (GS-7977; PSI-7977) and its metabolites in participants with HIV and hepatitis C virus (HCV) coinfection. Part B, the Phase 2 treatment study, will investigate the efficacy and safety of sofosbuvir, pegylated interferon alpha (PEG) and ribavirin (RBV) in participants with HIV/HCV coinfection.
