About

The purpose of this study was to evaluate the effect of treatment with ABT-450 co-formulated with ritonavir and ABT-267 (ABT-450/r/ABT-267) and ABT-333; 3-DAA regimen, with or without ribavirin (RBV) in adults with chronic hepatitis C virus genotype 1 (HCV GT1) infection.

Full description

This study (TOPAZ-II; M14-222), was a Phase 3b, open-label, multicenter study conducted in the United States which, together with its companion study TOPAZ-I (M14-423; NCT02219490) conducted outside of the United States, was designed with the primary objective of assessing the effect of treatment response on long-term clinical outcomes in adults with chronic HCV GT1 infection with or without compensated cirrhosis, who were either treatment-naïve or interferon/ribavirin (IFN/RBV) treatment- experienced. In both studies, participants were treated with the 3-DAA regimen with or without RBV. This study consisted of a screening period of up to 42 days, a treatment period of either 12 weeks for HCV GT1a-infected subjects without cirrhosis and for HCV GT1b-infected subjects without cirrhosis or with compensated cirrhosis or 24 weeks for GT1a-infected participants with compensated cirrhosis, and a 260-week post-treatment period.

ABT-450/r/ABT-267 plus ABT-333 with or without ribavirin (RBV)

Experimental group

Description:

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:

Drug: Ribavirin (RBV)

Drug: ABT-450/r/ABT-267

Drug: ABT-333
