A Study of Induction Dosing With PEGASYS (Peginterferon Alfa-2a [40KD]) Plus Copegus in Treatment-Naive Patients With Chronic Hepatitis C
- Conditions
- Hepatitis C, Chronic
- Interventions
- Registration Number
- NCT00394277
- Lead Sponsor
- Hoffmann-La Roche
- Brief Summary
This 4-arm study will compare the efficacy and safety of PEGASYS induction and maintenance dosing, versus standard fixed dosing in combination with Copegus, and the efficacy and safety of higher dose versus standard dose Copegus in combination with PEGASYS. Patients with chronic hepatitis C (CHC) genotype 1 infection of high viral titer, and baseline body weight ≥85 kg, will be randomized to one of 4 groups, to receive one of the following: a) PEGASYS 180 µg subcutaneously (sc) weekly plus Copegus 1200 mg orally (po) daily; b) PEGASYS 180 µg sc weekly plus Copegus 1400-1600 mg po daily; c)PEGASYS 360 µg sc weekly (induction) followed by 180 µg sc weekly (maintenance) plus Copegus 1200 mg po daily; or d) PEGASYS 360 µg sc weekly (induction) followed by 180 µg sc weekly (maintenance) plus Copegus 1400-1600 mg po daily. Following 48 weeks treatment, there will be a 24-week period of treatment-free follow-up. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.

- Primary Outcome Measures
Name Time Method Sustained Virological Response (SVR)-24 (Scheduled Treatment Period) Week 72 SVR-24 according to the scheduled treatment period was defined as the percentage of patients with undetectable HCV RNA at 24 weeks after completion of the treatment period (a single last HCV RNA PCR \<15 IU/mL measured at or after week 68 (ie, on or after study day 477).
- Secondary Outcome Measures
Name Time Method SVR-24 (Actual Treatment Period) 24 weeks after end of treatment SVR-24 according to the actual treatment period was defined as the percentage of patients with undetectable HCV RNA at least 20 weeks after the last dose of study drug.
SVR-12 (Scheduled Treatment Period) 12 weeks after end of treatment SVR-12 according to the scheduled treatment period was defined as the percentage of patients with undetectable HCV RNA at 12 weeks after the scheduled treatment period (a single last HCV RNA PCR \<15 IU/mL measured at or after week 60).
SVR-12 (Actual Treatment Period) 12 weeks after end of treatment SVR-12 according to the actual treatment period was defined as the percentage of patients with undetectable HCV RNA at least 12 weeks after the last dose of study drug.
