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
Brief 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.
