Open-Label, Bridging Study of Telaprevir in Treatment-Naïve and Treatment-Experienced Russian Patients With Genotype 1 Chronic Hepatitis C

January 29, 2015 updated by: Janssen-Cilag International NV

Open-Label, Bridging Study to Determine Efficacy and Safety of Telaprevir, Pegylated-Interferon-alfa-2a and Ribavirin in Treatment- Naïve and Treatment-Experienced Russian Subjects With Genotype 1 Chronic Hepatitis C

The purpose of this study is to determine the effectiveness, safety and tolerability of telaprevir administered as 750 mg every 8 hours (q8h) in combination with pegylated interferon (Peg-IFN)-alfa-2a and ribavirin (RBV) in treatment-naïve and treatment-experienced Russian participants with genotype 1 chronic hepatitis C.

Detailed Description

This is an open-label (all persons know the study drug assignment), multicenter study in treatment-naïve (participant did not receive any previous treatment for the treatment of hepatitis C) and treatment-experienced (participant did receive previous treatment for hepatitis C) Russian participants with genotype 1 chronic hepatitis C. After a screening period of approximately 4 weeks, participants will be treated for 12 weeks with telaprevir 750 mg every 8 hours in combination with Peg-IFN-alfa-2a and RBV followed by 12 or 36 weeks of treatment with Peg-IFN-alfa-2a and RBV alone depending on their liver disease status, response to previous treatment and individual virologic response during treatment in this study. After the treatment period, there is a follow-up phase of at least 12 weeks.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: Treatment-naïve
Treatment naïve participants will receive telaprevir 750 mg 8 hourly for 12 weeks in combination with Peg-IFN alfa-2a 180 microgram weekly and RBV 1000 - 1200 mg daily (dependent on weight) for 24 or 48 weeks. Total treatment duration will be based on participant's prior treatment status, liver disease status, and individual ontreatment virologic response in this study.
Drug: Telaprevir
Telaprevir Type = exact number, unit = mg, number = 750, form = tablet, route = oral. Telaprevir 750 mg (2 oral tablets) is taken every 8 hours for 12 weeks
Drug: Pegylated-interferon-alfa-2a
Pegylated-interferon-alfa-2a type = exact number, unit = microgram, number = 180, form = injection, route = subcutaneous. 180 microgram (µg) per week, subcutaneous injection, for 24 or 48 weeks
Drug: Ribavirin
Ribavirin Type = exact, number = 1000 or 1200, unit = mg, form = tablet, route = oral. 1000mg (if participant's weight is < 75kg) or 1200mg (if participant's weight is >= 75kg) per day for 24 or 48 weeks.
EXPERIMENTAL: Treatment-experienced
Treatment-experienced participants received telaprevir 750 mg 8 hourly for 12 weeks in combination with Peg-IFN alfa-2a 180 microgram weekly and RBV 1000 - 1200 mg daily (dependent on weight) for 24 or 48 weeks. Total treatment duration will be based on participant's prior treatment status, liver disease status, and individual on-treatment virologic response in this study.
