Sofosbuvir + Ribavirin for 12 Weeks in Subjects With Chronic Genotype 2 or 3 Hepatitis C Infection Who Are Interferon Intolerant, Interferon Ineligible or Unwilling to Take Interferon — POSITRON  

Chronic Hepatitis C Clinical Trial

Official title:
A Phase 3, Multicenter, Randomized, Double-Blind, Placebo-Controlled Study to Investigate the Efficacy and Safety of GS-7977 + Ribavirin for 12 Weeks in Subjects With Chronic Genotype 2 or 3 HCV Infection Who Are Interferon Intolerant, Interferon Ineligible or Unwilling to Take Interferon

Clinical Trial Summary

This multicenter study was to evaluate subjects with chronic genotype 2 or 3 HCV infection who were interferon (IFN) ineligible, IFN intolerant or unwilling to take IFN. Participants were randomized in a 3:1 ratio to receive sofosbuvir (SOF)+ribavirin (RBV), or placebo to match SOF+placebo to match RBV. Randomization was stratified by presence/absence of cirrhosis. Approximately 20% of participants may have had evidence of cirrhosis at screening.

Clinical Trial Description

Participants who were randomized to the placebo arm and completed all scheduled study procedures were eligible to receive active SOF+RBV in open-label Study GS-US-334-0109.

Participants who do not achieve sustained virologic response (SVR) were eligible for enrollment in the Sequence Registry Study GS-US-248-0123. The purpose of the Sequence Registry Study is to monitor the persistence of resistant mutations for up to 3 years.

Participants who achieved SVR were eligible for enrollment in the SVR Registry Study GS-US-248-0122. The purpose of the SVR Registry Study is to evaluate durability of SVR for up to 3 years after treatment. ;

Study Design

Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment
