Trial Outcomes & Findings for A Study to Evaluate Chronic Hepatitis C Infection in Adults With Genotype 1b Infection (NCT NCT01767116)

NCT ID: NCT01767116

Last Updated: 2021-07-12

Results Overview

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. The LLOQ for the assay was 25 IU/mL. The primary efficacy endpoints were noninferiority of the percentage of participants who achieved sustained virologic response 12 weeks after treatment in each treatment arm (ABT-450/r/ABT-267 and ABT-333, plus either placebo RBV or RBV) compared with the historical control rate for noncirrhotic, treatment-naïve participants with HCV GT1b infection treated with telaprevir and peginterferon/RBV (pegIFN).

PRIMARY outcome

Timeframe: 12 weeks after last dose of study drug

Population: All randomized participants who received at least 1 dose of study drug (intent-to-treat \[ITT\] population); participants with missing data were counted as non-responders.

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. The LLOQ for the assay was 25 IU/mL.

Virologic failure during treatment was defined as rebound (confirmed HCV RNA greater than or equal to the lower limit of quantitation \[≥ LLOQ\] after HCV RNA \< LLOQ during treatment, or confirmed increase from the lowest value post baseline in HCV RNA \[2 consecutive HCV RNA measurements \> 1 log10 IU/mL above the lowest value post baseline\] at any time point during treatment), or failure to suppress (HCV RNA ≥ LLOQ persistently during treatment with at least 6 weeks \[≥ 36 days\] of treatment).
