Brief summary:
The purpose of this phase 2/3, open-label, multipart, multicenter study was to evaluate the efficacy, and safety of co-administration of ABT-493 and ABT-530 with and without ribavirin (RBV) in chronic HCV genotype 2 (GT2-), genotype 3 (GT3-), genotype 4 (GT4), genotype 5 (GT5-), or genotype 6 (GT6-) infected participants with or without cirrhosis.

Detailed description:
The study consisted of four independent parts with treatment and post-treatment periods of enrollment. Parts 1 and 2 were the supportive/ exploratory parts (phase 2) of the study and part 3 and 4 were the confirmatory/ registrational parts (phase 3) of the study. In parts 1 and 2 of the study, ABT-493 and ABT-530 were co-administered as separate tablets. However, in parts 3 and 4 of the study, the ABT-493/ABT-530 co-formulated tablets were administered.

Arms: arm 1: ABT-493 (300 mg) once daily (QD) co-administered with ABT-530 (120 mg) QD for 12 weeks in HCV genotype 2 (GT2) -infected treatment naïve and treatment experienced participants without cirrhosis. arm 2: ABT-493 (200 mg) once daily (QD) co-administered with ABT-530 (120 mg) QD for 12 weeks in HCV GT2 -infected treatment naïve and treatment experienced participants without cirrhosis. arm 3: ABT-493 (200 mg) once daily (QD) co-administered with ABT-530 (120 mg) QD and weight-based ribavirin (RBV) divided twice daily (BID) for 12 weeks in HCV GT2 -infected treatment naïve and treatment experienced participants without cirrhosis. arm 4: ABT-493 (300 mg) once daily (QD) co-administered with ABT-530 (120 mg) QD for 12 weeks in HCV genotype 3 (GT3) -infected treatment naïve and treatment experienced participants without cirrhosis. arm 5: ABT-493 (200 mg) once daily (QD) co-administered with ABT-530 (120 mg) QD for 12 weeks in HCV GT3 -infected treatment naïve and treatment experienced participants without cirrhosis. arm 6: ABT-493 (200 mg) once daily (QD) co-administered with ABT-530 (120 mg) QD and weight-based ribavirin (RBV) divided BID for 12 weeks in HCV GT3 -infected treatment naïve and treatment experienced participants without cirrhosis. arm 7: ABT-493 (200 mg) once daily (QD) co-administered with ABT-530 (40 mg) QD for 12 weeks in HCV GT3 -infected treatment naïve and treatment experienced participants without cirrhosis. arm 8: ABT-493 (200 mg) once daily (QD) co-administered with ABT-530 (120 mg) QD for 8 weeks in HCV GT2 -infected treatment naïve and treatment experienced participants without cirrhosis. arm 9: ABT-493 (200 mg) once daily (QD) co-administered with ABT-530 (40 mg) QD for 8 weeks in HCV GT2 -infected treatment naïve and treatment experienced participants without cirrhosis. arm 10: ABT-493 (300 mg) once daily (QD) co-administered with ABT-530 (120 mg) QD for 8 weeks in HCV GT2 -infected treatment naïve and treatment experienced participants without cirrhosis. arm 11: ABT-493 (200 mg) once daily (QD) co-administered with ABT-530 (120 mg) QD for 8 weeks in HCV GT3 -infected treatment naïve and treatment experienced participants without cirrhosis. arm 12: ABT-493 (300 mg) once daily (QD) co-administered with ABT-530 (120 mg) QD for 8 weeks in HCV GT3 -infected treatment naïve and for 12 weeks in HCV GT3 -infected treatment experienced participants without cirrhosis. arm 13: ABT-493 (200 mg) once daily (QD) co-administered with ABT-530 (80 mg) QD for 12 weeks in HCV GT3 -infected treatment naïve participants with compensated cirrhosis. arm 14: ABT-493 (200 mg) once daily (QD) co-administered with ABT-530 (80 mg) QD and ribavirin (RBV) (800 mg) QD for 12 weeks in HCV GT3 -infected treatment naïve participants with compensated cirrhosis. arm 15: ABT-493 (300 mg) once daily (QD) co-administered with ABT-530 (120 mg) QD for 12 weeks in HCV GT3 -infected treatment naïve participants with compensated cirrhosis and for 16 weeks in HCV GT3 -infected treatment-experienced participants with compensated cirrhosis. arm 16: ABT-493 (300 mg) once daily (QD) co-administered with ABT-530 (120 mg) QD and RBV (800 mg) QD for 12 weeks in HCV GT3-infected treatment naïve and treatment-experienced participants with compensated cirrhosis. arm 17: ABT-493/ ABT-530 (300 mg/ 120mg ) once daily (QD) for 12 weeks in HCV GT3 -infected treatment naïve participants with cirrhosis. arm 18: ABT-493/ ABT-530 (300 mg/ 120mg ) once daily (QD) for 12 weeks in HCV GT3 -infected treatment experienced participants without cirrhosis. arm 19: ABT-493/ ABT-530 (300 mg/ 120 mg) QD for 16 weeks in HCV GT3 -infected treatment experienced participants without cirrhosis. arm 20: ABT-493/ ABT-530 (300 mg/ 120 mg) QD for 16 weeks in HCV GT3 -infected treatment experienced participants with cirrhosis. arm 21: ABT-493/ ABT-530 (300 mg/ 120 mg) QD for 8 weeks in HCV GT2 infected treatment naïve and treatment experienced participants without cirrhosis. arm 22: ABT-493/ ABT-530 (300 mg/ 120 mg) QD for 8 weeks in HCV GT4-6 infected treatment naïve and treatment experienced participants without cirrhosis.
