Brief summary:
The purpose of this Phase 2, open-label, 2-part, multicenter study was to evaluate the efficacy, safety, and pharmacokinetics of co-administration of ABT-493 and ABT-530 with and without ribavirin (RBV) at different doses in chronic Hepatitis C virus (HCV) Genotype 1 (GT1), Genotype 4 (GT4), Genotype 5 (GT5), and Genotype 6 (GT6) infection with compensated cirrhosis (GT1 only) or without cirrhosis (GT1, GT4, GT5, or GT6). Although RBV was initially planned in the protocol, it was not administered in any of the study arms.

Detailed description:
This study consisted of two independent parts: Part 1 was conducted first followed by Part 2. Part 1 enrolled participants who received ABT-493 and ABT-530 for 12 weeks; Part 2 enrolled participants who received ABT-493 and ABT-530 for 8 or 12 weeks. Participants who completed or prematurely discontinued the treatment period were followed for 24 weeks to monitor HCV RNA to evaluate efficacy and the emergence and persistence of viral variants.

Arms:
arm 1: ABT-493 200 mg once daily (QD) + ABT-530 120 mg QD for 12 weeks in HCV genotype 1-infected participants without cirrhosis arm 2: ABT-493 200 mg once daily (QD) + ABT-530 40 mg QD for 12 weeks in HCV genotype 1- infected participants without cirrhosis arm 3: ABT-493 200 mg once daily (QD) + ABT-530 120 mg QD for 8 weeks in HCV genotype 1-infected participants without cirrhosis (never opened - Sponsor decision) arm 4: ABT-493 200 mg once daily (QD) + ABT-530 40 mg QD for 8 weeks in HCV genotype 1-infected participants without cirrhosis (never opened - Sponsor decision) arm 5: ABT-493 200 mg once daily (QD) + ABT-530 120 mg QD + ribavirin (RBV) 800 mg QD for 12 weeks in HCV genotype 1-infected participants with compensated cirrhosis (never opened - Sponsor decision) arm 6: ABT-493 200 mg once daily (QD) + ABT-530 120 mg QD for 12 weeks in HCV genotype 1- infected participants with compensated cirrhosis arm 7: ABT-493 200 mg once daily (QD) + ABT-530 40 mg QD + ribavirin (RBV) 800 mg QD for 12 weeks in HCV genotype 1-infected participants with compensated cirrhosis (never opened - Sponsor decision) arm 8: ABT-493 200 mg once daily (QD) + ABT-530 40 mg QD for 12 weeks in HCV genotype 1-infected participants with compensated cirrhosis (never opened - Sponsor decision) arm 9: ABT-493 300 mg once daily (QD) + ABT-530 120 mg QD for 12 weeks in HCV genotype 4-, 5-, and 6-infected participants without cirrhosis arm 10: ABT-493 200 mg once daily (QD) + ABT-530 40 mg QD for 12 weeks in HCV genotype 4-, 5-, and 6-infected participants without cirrhosis (never opened - Sponsor decision) arm 11: ABT-493 300 mg once daily (QD) + ABT-530 120 mg QD for 8 weeks in HCV genotype 1- infected participants without cirrhosis
