Dose-Ranging Study of Sofosbuvir in Combination With Pegylated Interferon and Ribavirin in Treatment Naïve GT 1 HCV Patients

Hepatitis C Clinical Trial

Official title:
A Multi-center, Double-Blind, Parallel Group, Randomized, Placebo-Controlled, Dose Ranging Study to Investigate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Following Oral Administration of PSI-7977 in Combination With Standard of Care (Pegylated Interferon and Ribavirin) in Treatment-Naïve Patients With Chronic HCV Infection Genotype 1

Clinical Trial Summary

Participants with genotype 1 HCV infection were randomized to 1 of 3 sofosbuvir doses (100 mg, 200 mg, or 400 mg) or matching placebo once daily based upon stratification for IL28B status (CC or CT/TT). Placebo tablets were administered to participants receiving 100 mg active sofosbuvir (3 placebo tablets) and 200 mg active sofosbuvir (2 placebo tablets) in order to maintain the study blind. Participants received sofosbuvir/matching placebo from Day 0 to 27. Participants also received treatment with PEG+RBV starting on Day 0 of the study which continued for 48 weeks. Participants were evaluated for sustained virologic response (SVR) for an additional 24 weeks following completion of study treatment.
