Description of intervention(s) / exposure
Treatment: Drugs - ABT-450/r/ABT-267
Treatment: Drugs - ABT-333
Treatment: Drugs - Ribavirin (RBV)

Experimental: ABT-450/r/ABT-267 plus ABT-333 with or without ribavirin (RBV) - Participants with HCV GT1b without cirrhosis received the 3-DAA (ABT-450/ritonavir/ABT-267 and ABT-333) regimen: two 75 mg ABT-450/50 mg ritonavir/12.5 mg ABT-267 tablets taken orally every morning (QD) and one ABT-333 250 mg tablet taken orally twice a day (BID) for 12 weeks. Participants with HCV GT1a without cirrhosis and those with HCV GT1b with cirrhosis received the 3-DAA regimen and weight-based ribavirin (RBV; 1000 to 1200 mg divided twice daily per local label) for 12 weeks. Participants with HCV GT1a with cirrhosis received the 3-DAA regimen and weight-based RBV per local label for 24 weeks.


Treatment: Drugs: ABT-450/r/ABT-267
Tablet for oral use

Treatment: Drugs: ABT-333
Tablet for oral use

Treatment: Drugs: Ribavirin (RBV)
Ribavirin was provided as 200 mg tablets, and dosed based on weight, 1000 to 1200 mg divided twice daily per local label. For example, for participants weighing \< 75 kg, RBV may have been taken orally as 2 tablets in the morning and 3 tablets in the evening which corresponds to a 1000 mg total daily dose. For participants weighing = 75 kg, RBV may have been taken orally as 3 tablets in the morning and 3 tablets in the evening which corresponds to a 1200 mg total daily dose.
