Summary
Brief summary
This study will evaluate the antiviral efficacy of combination therapy with sofosbuvir (SOF) plus ribavirin (RBV) for 48 weeks in adults with compensated and decompensated chronic hepatitis C virus (HCV) infection. Approximately 50 adults will be randomized (1:1) to receive study drug for 48 weeks or take part in an untreated observational arm for the first 24 weeks followed by study drug for another 48 weeks.
