Efficacy and Safety of Ypeginterferon Alfa-2b in Chronic Hepatitis C (PEGIFN)

January 31, 2013 updated by: Xiamen Amoytop Biotech Co., Ltd.

A Multi-center, Randomized, Open-label and Positive Controlled Phase II Clinical Trial to Assess Efficacy and Safety of Ypeginterferon Alfa-2b in Chronic Hepatitis C.

This study is a multi-center, randomized, open-label and positive controlled Phase II Clinical trial to assess the efficacy and safety of Ypeginterferon alfa-2b (with Ribavirin), once a week, in 3 dose-groups respectively, for treatment of Chronic Hepatitis C patients, with Pegasys 180mcg/week & Ribavirin as positive control. It is aimed to establish a dose response and safety relationship sufficient to allow the subsequent design and conduct of Phase III trials, and generate the PK data in hepatitis C patients to satisfy regulatory requirements.
