A Multicenter Phase 3 Study of Interferon-beta-1a for the Treatment of Chronic Hepatitis C in Asian Subjects

August 4, 2013 updated by: EMD Serono

A Multicentre Phase III Study of Interferon-beta-1a for the Treatment of Chronic Hepatitis C in Asian Subjects

The main objective of this study is to establish interferon-beta-1a as the treatment of choice for chronic Hepatitis C with better efficacy and safety profiles in monotherapy or combination therapy.

This will be a multicenter, randomized, double-blind, placebo-controlled study with a placebo to be crossed-over to a combination of interferon-beta-1a and ribavirin or no treatment during an open-label extension phase. The duration of the trial will be 48 weeks, with a double-blind period of 12 weeks.

The study will recruit 257 eligible subjects of either sex. It will be conducted by approximately 16 Investigators / investigational centers in 3 countries (China, Hong Kong and Singapore).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Interferon-beta-1a
Interferon-beta-1a will be administered subcutaneously at a dose of 44 microgram (mcg), three times a week up to Week 24
Active Comparator: Ribavarin plus interferon-beta-1a
Matching placebo will be administered subcutaneously three times a week for 12 weeks. The placebo responders will continue the study off-treatment after Week 12 up to Week 24
Placebo non-responders at Week 12 will receive ribavirin at a dose of 1000 milligram (mg) or 1200 mg orally once daily in combination with Interferon-beta-1a, administered subcutaneously at a dose of 44 mcg three times a week, from Week 16 up to Week 24
