Participants with HCV GT1b without cirrhosis received the adult 3-DAA (OBV/PTV/RTV and DSV) regimen: two 12.5 mg ombitasvir /75 mg paritaprevir /50 mg ritonavir tablets taken orally every morning (QD) and one dasabuvir 250 mg tablet taken orally twice a day (BID) for 12 weeks. Participants with HCV GT1a without cirrhosis received 12-week treatment with the adult 3-DAA regimen and ribavirin 200 mg tablets were administered orally per local label.

Participants with HCV GT1a without cirrhosis received 12-week treatment with the adult 3-DAA regimen and ribavirin 200 mg tablets were administered orally per local label. Participants with HCV GT1a with compensated cirrhosis received 24-week treatment with the adult 3-DAA regimen and ribavirin 200 mg tablets were administered orally per local label. Participants with HCV GT4 received 12-week treatment with the OBV/PTV/RTV formulation and ribavirin 200 mg tablets were administered orally per local label.
Participants with HCV GT1b without cirrhosis were to receive the mini-tablet 3-DAA (OBV, PTV, RTV, and DSV) regimen for 12 weeks: ombitasvir 0.3 mg, paritaprevir 1.0 mg, and ritonavir 1.0 mg mini-tablets administered orally QD based on body weight and dasabuvir taken orally BID as 3.08 mg mini-tablets based on body weight. Participants with HCV GT1a without cirrhosis received 12-week treatment with the mini-tablet 3-DAA regimen and ribavirin was provided as a 40 mg/mL oral solution and administered per local label.
