A Study of Debio 025 in Combination With PegIFN Alpha-2a and Ribavirin in Chronic HCV Patients Non-Responders to Standard Treatment - Full Text View

Sponsored by:	Debiopharm S.A.
Information provided by:	Debiopharm S.A.
ClinicalTrials.gov Identifier:	NCT00537407

Purpose

Debio 025 is an oral cyclophilin inhibitor with a new mechanism of action demonstrating potent anti-hepatitis C virus (HCV) activity in pre-clinical models and patients.. The current standard of care (SOC) in HCV patients consists of a combination of peg-IFN alpha and ribavirin. Treatment duration and ribavirin dose depend on the genotype treated. Only 40-50% of patients with genotype 1 achieve a sustained viral response (SVR). This study will assess whether Debio 025 administered in combination with peg-IFN alpha 2a and ribavirin can improve the outcome of treatment in this group of patients.

Detailed Description:

This is a multicentre, open-label, randomized, 5 arm parallel-group, multiple dose study in 50 chronic HCV genotype 1 non-responders to standard treatment with peg-IFN alpha (2a or 2b) and ribavirin for at least 12 weeks. The entire study will last a maximum of 96 weeks and will consist of a 48- or 72-week treatment period (according to response) divided into 2 distinct treatment parts. A follow up visit to assess SVR will take place 24 weeks after treatment cessation, i.e. at study Week 72 or 96.
