Study type | Interventional |
This is an open-label, single-arm study of sofosbuvir (GS-7977) and ribavirin (RBV) in adults who have had a liver transplant which has become re-infected with hepatitis C. The treatment period is 24 weeks with up to 48 weeks of follow up. The total time in this study will last up to 72 weeks not including the screening visit.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Percentage of Participants With Sustained Virologic Response 12 Weeks After Discontinuation of Therapy (SVR12) | SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ; ie, < 25 IU/mL) 12 weeks following the last dose of study drug. | Posttreatment Week 12 | No |
Primary | Percentage of Participants Who Discontinue Study Drug Due to an Adverse Event | Baseline to Week 24 | No | |
Secondary | Percentage of Participants With Sustained Virologic Response (SVR) at 4, 24, and 48 Weeks After Discontinuation of Therapy (SVR4, SVR24, and SVR48) | SVR4, SVR 24, and SVR 48 were defined as HCV RNA < LLOQ 4, 24, and 48 weeks following the last dose of study drug, respectively. | Posttreatment Weeks 4, 24, and 48 | No |
Secondary | Percentage of Participants With HCV RNA < LLOQ at Weeks 12 and 24 | Weeks 12 and 24 | No | |
Secondary | HCV RNA and Change From Baseline at Weeks 2, 4, and 8 | Baseline; Weeks 2, 4, and 8 | No | |
Secondary | Percentage of Participants With Virologic Failure | Virologic failure was defined as on-treatment virologic failure or virologic relapse. On-treatment virologic failure: HCV RNA < LLOQ during treatment with subsequent detectable HCV RNA while continuing treatment Virologic relapse: HCV RNA < LLOQ at last observed on-treatment HCV RNA measurement and HCV RNA = LLOQ after stopping treatment (2 consecutive HCV RNA measurements or last available HCV RNA measurement) |
Up to Posttreatment Week 24 | No |
