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.

SVR12 was defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) level less than the lower limit of quantification \[\<LLOQ\]) 12 weeks after the last dose of study drug.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Sustained Virologic Response 4 Weeks Post-treatment (SVR4)4 weeks after the last actual dose of study drug

Percentage of Participants With Post-treatment RelapseFrom the end of treatment through 12 weeks after the last dose of study drug

Post-treatment relapse was defined as confirmed HCV RNA ≥ LLOQ between the end of treatment and 12 weeks after the last dose of study drug among participants who completed treatment with HCV RNA levels \< LLOQ at the end of treatment, excluding reinfection.

Percentage of Participants With On-treatment Virologic FailureUp to end of treatment (treatment week 8, 12 or 16 depending on arm) or premature discontinuation from treatment

On-treatment virologic failure was defined as confirmed HCV RNA ≥ LLOQ after HCV RNA \< LLOQ during treatment; confirmed increase of \> 1 log(subscript)10(subscript) IU/mL above the lowest value post-baseline in HCV RNA during treatment; or HCV RNA ≥ LLOQ at end of treatment with at least 6 weeks of treatment.
