简要总结
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.

主要结局
Incidence of Adverse Events Leading to Permanent Discontinuation of Study Drug(s)
时间窗: Up to 12 weeks
The percentage of participants discontinuing any study drug due to an adverse event was summarized.
Part A: Plasma Pharmacokinetics of SOF, EFV, Tenofovir (TFV), and FTC: AUCtau at Day 7
时间窗: Pre-dose and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12 hours postdose
AUCtau: concentration of drug over time (area under the plasma concentration versus time curve over the dosing interval). Data for this outcome measure were collected for participants in Part A only.
Part A: Plasma Pharmacokinetics of SOF, EFV, TFV, and FTC: Cmax at Day 7
时间窗: Pre-dose and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12 hours postdose
Cmax: maximum observed concentration of drug in plasma. Data for this outcome measure were collected for participants in Part A only.
Part B: Percentage of Participants With Sustained Virologic Response (SVR) at 12 Weeks After Discontinuation of Therapy (SVR12)
时间窗: Posttreatment Week 12
SVR12 was defined as HCV RNA \< the lower limit of quantitation (LLOQ; ie, 25 IU/mL) at 12 weeks after stopping study treatment. Data for this outcome measure were collected for participants in Part B only.
