A Study to Evaluate Chronic Hepatitis C Infection

July 8, 2021 updated by: AbbVie (prior sponsor, Abbott)

A Randomized, Double-blind, Placebo-controlled Study to Evaluate the Efficacy and Safety of ABT-450/Ritonavir/ABT-267 (ABT-450/r/ABT-267) and ABT-333 Co-administered With Ribavirin (RBV) in Treatment-Naïve Adults With Genotype 1 Chronic Hepatitis C Virus (HCV) Infection (SAPPHIRE-I)

The purpose of this study is to evaluate the safety and efficacy of ABT-450, ritonavir and ABT-267 (ABT-450/r/ABT-267; ABT-267 also known as ombitasvir) and ABT-333 (also known as dasabuvir) co-administered with ribavirin (RBV) in hepatitis C virus genotype 1 infected treatment-naïve adults.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Sustained Virologic Response 12 Weeks After Treatment
Time Frame: 12 weeks after the last actual dose of active study drug
The percentage of participants with sustained virologic response (plasma Hepatitis C virus ribonucleic acid [HCV RNA] level less than the lower limit of quantitation [< LLOQ]) 12 weeks after the last dose of study drug.
12 weeks after the last actual dose of active study drug

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Normalization of Alanine Aminotransferase (ALT) at Final Treatment Visit During the Double-Blind Treatment Period
Time Frame: At 12 weeks
Normalization is defined as alanine aminotransferase less than or equal to the upper limit of normal (ULN) at final treatment visit for participants with alanine aminotransferase greater than ULN at baseline.
At 12 weeks
Percentage of HCV Genotype 1a-infected Participants With Sustained Virologic Response 12 Weeks After Treatment
Time Frame: 12 weeks after the last actual dose of active study drug
The percentage of participants with sustained virologic response (plasma Hepatitis C virus ribonucleic acid [HCV RNA] level less than the lower limit of quantitation [< LLOQ]) 12 weeks after the last dose of study drug.
12 weeks after the last actual dose of active study drug
Percentage of HCV Genotype 1b-infected Participants With Sustained Virologic Response 12 Weeks After Treatment
Time Frame: 12 weeks after the last actual dose of active study drug
The percentage of participants with sustained virologic response (plasma Hepatitis C virus ribonucleic acid [HCV RNA] level less than the lower limit of quantitation [< LLOQ]) 12 weeks after the last dose of study drug.
12 weeks after the last actual dose of active study drug
Percentage of Participants With On-treatment Virologic Failure During the Double-blind Treatment Period: ABT-450/r/ABT-267 and ABT-333, Plus RBV Arm
Time Frame: 12 weeks after the last actual dose of active study drug
Virologic failure was defined as rebound (hepatitis C virus ribonucleic acid [HCV RNA] ≥ lower limit of quantification [LLOQ] after HCV RNA < LLOQ or increase in HCV RNA of at least 1 log10 IU/mL) or failure to suppress (all on-treatment values of plasma HCV RNA ≥ LLOQ with at least 36 days of treatment) during treatment.
12 weeks after the last actual dose of active study drug
Percentage of Participants With Virologic Relapse After Treatment: ABT-450/r/ABT-267 and ABT-333, Plus RBV Arm
Time Frame: Within 12 weeks post-treatment
Participants were considered to have virologic relapse after treatment if they had confirmed quantifiable plasma hepatitis C virus ribonucleic acid (HCV RNA) greater than or equal to the lower limit of quantification (≥ LLOQ) between the end of treatment and 12 weeks after the last dose of study drug among participants who completed treatment with HCV RNA < LLOQ at the end of treatment.
Within 12 weeks post-treatment
