Intervention/exposure
Study type
Interventional(has expanded access)
Description of intervention(s) / exposure
Treatment: Drugs - Sofosbuvir
Treatment: Drugs - RBV

Experimental: SOF+RBV - Participants will receive sofosbuvir+RBV for 24 weeks.


Treatment: Drugs: Sofosbuvir
Sofosbuvir 400 mg tablet administered orally once daily

Treatment: Drugs: RBV
Ribavirin (RBV) 200-mg tablet(s) administered orally in a divided daily dose starting at 400 mg, subsequently adjusted (range: 200 to 1200 mg in a divided daily dose) based upon a number of factors including hemoglobin value, creatinine clearance, and weight.

Outcomes
Primary outcome [1] 0 0
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.

Baseline to Week 24
Secondary outcome [1] 0 0
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.

Baseline; Weeks 2, 4, and 8
Secondary outcome [4] 0 0
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)
Timepoint [4] 0 0
Up to Posttreatment Week 24
