A Study of Debio 025 Combined With Peg-IFNα2a and Ribavirin in Treatment Naïve Chronic Hepatitis C Genotype 1 Patients
A Multicentre, Randomised, Double-blind, Placebo-controlled, Parallel-group Phase II Study on the Efficacy and Safety of Debio 025 Combined With Peg-IFNα2a and Ribavirin in Treatment naïve Chronic Hepatitis C Genotype 1 Patients

The purpose of this study is to compare several Debio 025/peg-IFNα2a/ribavirin triple therapies with the current standard of care (SOC) in treatment naïve chronic hepatitis C genotype 1 patients.

This is an international, multicentre, randomised, double-blind, placebo-controlled, 4-arm parallel-group multiple dose phase II study comparing three Debio 025/peg-IFNα2a/ribavirin regimens to standard of care (SOC) treatment in 272 treatment naïve chronic HCV genotype 1 patients.

Patients will be randomised into one of 4 arms receiving either Debio 025/peg-IFNα2a/ribavirin triple therapy for a fixed treatment duration of 48 (Treatment A) or 24 (Treatment B) weeks, or Debio 025/peg-IFNα2a/ribavirin triple therapy for a response-based treatment duration of 24 or 48 weeks (Treatment C), or blinded SOC treatment for 48 weeks (Treatment D). Follow up will last 24 weeks in all treatment arms.

In 48-week treatment arms (Treatments A, C, and D), the entire study will last a maximum of 76 weeks, including a screening period of about 4 weeks, a 48-week treatment period and a 24-week follow up period. In 24-week treatment arms (Treatment B and C), the entire study will last a maximum of 52 weeks, including a screening period of about 4 weeks, a 24-week treatment period and a 24-week follow up period.
