Description of intervention(s) / exposure
Treatment: Drugs - LDV/SOF
Treatment: Drugs - RBV

Experimental: LDV/SOF+RBV 12 weeks (Group 1) - Participants who failed a prior SOF+RBV ± pegylated interferon (Peg-IFN) regimen will receive LDV/SOF FDC plus RBV for 12 weeks.

Experimental: LDV/SOF 24 weeks (Group 2) - Participants who failed a prior LDV/SOF ± RBV regimen will receive LDV/SOF FDC for 24 weeks.

Experimental: LDV/SOF+RBV 24 weeks (Group 3) - Participants with advanced compensated or decompensated cirrhosis who failed a prior SOF+RBV regimen will receive LDV/SOF FDC plus RBV for 24 weeks.


Treatment: Drugs: LDV/SOF
Tablet(s) administered orally once daily

Treatment: Drugs: RBV
Tablets administered orally in a divided daily dose according to package insert weight-based dosing recommendations (\< 75 kg = 1000 mg and = 75 kg = 1200 mg)

Participants in the LDV/SOF+RBV 24 weeks group will dose adjust RBV according to hemoglobin and renal status as stated in the RBV package insert.
