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.

Primary Outcome Measures:
  • Percentage of Participants With Sustained Virologic Response 12 Weeks After Discontinuation of Therapy (SVR12) [ Time Frame: Posttreatment Week 12 ]
    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.

  • Percentage of Participants Who Discontinue Study Drug Due to an Adverse Event [ Time Frame: Baseline to Week 24 ]

Secondary Outcome Measures:
  • Percentage of Participants With Sustained Virologic Response (SVR) at 4, 24, and 48 Weeks After Discontinuation of Therapy (SVR4, SVR24, and SVR48) [ Time Frame: Posttreatment Weeks 4, 24, and 48 ]
    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.

  • Percentage of Participants With HCV RNA < LLOQ at Weeks 12 and 24 [ Time Frame: Weeks 12 and 24 ]
  • HCV RNA and Change From Baseline at Weeks 2, 4, and 8 [ Time Frame: Baseline; Weeks 2, 4, and 8 ]
  • Percentage of Participants With Virologic Failure [ Time Frame: Up to Posttreatment Week 24 ]

    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)

Enrollment: 40

Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: SOF+RBV
Participants will receive sofosbuvir+RBV for 24 weeks.
Drug: Sofosbuvir
Sofosbuvir 400 mg tablet administered orally once daily
Other Names:
  • GS-7977
