Study summary

The purpose of this study is to evaluate the safety and antiviral activity of ABT-450/ritonavir/ABT-267 (ABT-450/r/ABT-267; ABT-450 also known as paritaprevir; ABT-267 also known as ombitasvir) and ABT-333 (also known as dasabuvir) with and without ribavirin (RBV) in patients with chronic hepatitis C virus genotype 1b (HCV GT1b) infection without cirrhosis.

Read the detailed description

A randomized, double-blind, multicenter study to evaluate the safety and antiviral activity of the combination of ABT-450/ritonavir/ABT-267 (ABT-450/r/ABT-267) and ABT-333 with and without ribavirin (RBV) in treatment-naïve, noncirrhotic participants with chronic hepatitis C virus genotype 1b (HCV GT1b) infection.

What researchers measure

Primary outcomes

  1. Percentage of Participants With Sustained Virologic Response 12 Weeks After Treatment; Noninferiority Analyses of Each Treatment Arm Compared to Historical Rate

    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).

    Time frame: 12 weeks after last dose of study drug

Secondary outcomes

  1. Percentage of Participants With Sustained Virologic Response 12 Weeks After Treatment; Noninferiority Analysis of ABT-450/r/ABT-267 and ABT-333, Plus Placebo RBV Compared With ABT-450/r/ABT-267 and ABT-333, Plus RBV

    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 secondary endpoint was the noninferiority of the percentage of participants who achieved sustained virologic response 12 weeks after treatment who received ABT-450/r/ABT-267 and ABT-333, plus placebo RBV compared with those who received ABT-450/r/ABT-267 and ABT-333, plus RBV.

    Time frame: 12 weeks after last dose of study drug

  2. Percentage of Participants With Hemoglobin Decrease to Below the Lower Limit of Normal (LLN) At End of Treatment

    The percentage of participants with a decrease in hemoglobin from greater than or equal to the lower limit of normal (≥ LLN) at baseline to \< LLN at the end of treatment.

    Time frame: Baseline (Day 1) and Week 12 (End of Treatment)

  3. Percentage of Participants With Sustained Virologic Response 12 Weeks After Treatment; Superiority Analyses of Each Treatment Arm Compared to Historical Rate

    The percentage of participants with sustained virologic response (plasma HCV RNA less than the lower limit of quantitation \[\< LLOQ\]) 12 weeks after the last dose of study drug. The secondary efficacy endpoints were superiority 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 treated with telaprevir and pegIFN/RBV.

    Time frame: 12 weeks after last dose of study drug

  4. Percentage of Participants With Virologic Failure During Treatment

    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).

    Time frame: Baseline (Day 1), and Treatment Weeks 1, 2, 4, 6, 8, 10, and 12

  5. Percentage of Participants With Virologic Relapse After Treatment

    Participants who completed treatment with plasma HCV RNA less than the lower limit of quantification (\<LLOQ) at the end of treatment were considered to have virologic relapse if they had confirmed HCV RNA ≥ LLOQ during the post-treatment period.

    Time frame: Between End of Treatment (Week 12) and Post-treatment (up to Week 12 Post-treatment)
