Study Details

Study Description

Brief Summary

The objective of the study is to select an optimal dose of taribavirin by comparing the efficacy and safety of 3 taribavirin dose levels, 20, 25, and 30 mg/kg/day, versus ribavirin 800 to 1400 mg/day based on body weight, both administered in combination with peginterferon alfa-2b to therapy-naive patients with chronic Hepatitis C Virus (HCV) genotype 1 infection.

  • Outcome Measures

    Primary Outcome Measures

    1. Patients With Either Undetectable Serum HCV RNA (<100 Copies/ml) or at Least a 2-log Decrease From Baseline in Serum Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) at Treatment Week 12. [Treatment Week 12]

      The primary efficacy endpoint was the numbers of responders at Treatment Week (TW) 12. Responders are defined as patients achieving either viral negativity or a partial response (PR). Viral negativity is defined as <100 copies/mL serum HCV RNA. A PR is defined as < 100 copies/mL serum HCV RNA and at least a 2-log decrease from baseline in serum HCV RNA levels. Responder rates with corresponding 95% confidence intervals were estimated for each treatment group.

    Secondary Outcome Measures

    1. Patients With Anemia (Hemoglobin <10 g/dL) Up to Follow-up Week 24 [Treatment Week Follow-Up 24]

      The primary safety endpoint will be the numbers of patients with hemoglobin <10 g/dL (anemia) at any time during the treatment period. The comparison of anemia rates between taribavirin and ribavirin groups will be carried out using the Fisher's exact test or Chi-square test. The 95% confidence interval of the difference in proportion will be analyzed.

    2. Patients With Undetected Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) (<100 Copies/mL) at Treatment Week Follow-Up 24 [Treatment Week Follow-Up 24]

    3. Relapsers at Follow-Up Visit 24 [Follow-Up Week 24]

      Includes patients who had undetectable Hepatitis Virus C (HVC) Ribonucleic Acid (RNA) at their last visit on drug.

    Study Results

    Participant Flow

    Recruitment Details Patients who met all entry criteria and signed an informed consent were randomized in a 1:1:1:1 ratio to one of the 4 arms by a central randomization schedule. A total of 51 clinical centers in the United States participated in the study. 278 patients were randomized; 275 patients who receive one dose of study drug were included in all analyses.
    Pre-assignment Detail Randomization was stratified by screening HCV RNA viral load less than or = to 2 or greater than (>) 2 million copies/mL and body weight (BW) (less than or = 75 or >75 kg). A cap of 70% was set for patients with BWs >75 kg so that at least 30% of the patients in each group have BWs less than or = to 75 kg.

The comparison of anemia rates between taribavirin and ribavirin groups will be carried out using the Fisher's exact test or Chi-square test. The 95% confidence interval of the difference in proportion will be analyzed.
    Time Frame Treatment Week Follow-Up 24

    Outcome Measure Data

    Analysis Population Description
