Efficacy and Safety Study of Peginterferon Alfa-2b in Chinese Chronic Hepatitis C Patients

October 6, 2014 updated by: Xiamen Amoytop Biotech Co., Ltd.

A Phase 3, Randomized, Multi-center, Active-Controlled, Open-label Study to Evaluate the Efficacy and Safety of Peginterferon Alfa-2b (40kD, Y Shape) in Combination With Ribavirin in Chinese Chronic Hepatitis C Patients

The purpose of this study is to evaluate the efficacy and safety of Peginterferon alfa-2b (40KD, Y shape, the followings will refer as Ypeginterferon alfa-2b for short), at a dose of 180μg/week, in combination with Ribavirin in Chinese chronic hepatitis C patients. The study will first group patients into two sub-study, genotype 2/3 and non-genotype 2/3, depending on the HCV genotype that infected. In the genotype 2/3 sub-study about 219 patients will be enrolled, and eligible patients are randomized at 2:1 ratio into Ypeginterferon alfa-2b group or active control group (Pegasys), receiving 24 weeks of interferon therapy and oral daily Ribavirin at a dose of 800mg/d. In the non-genotype 2/3 sub-study about 507 patients will be enrolled, and eligible patients are randomized at 2:1 ratio into Ypeginterferon alfa-2b group or active control group (Pegasys), receiving 48 weeks of interferon therapy and oral daily Ribavirin 1000-1200mg/day , basing on body weight. All patients will be followed for 24 weeks after the end of therapy.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Proportion of patients with sustained virologic response (defined as HCV RNA<15IU/ml at 24 weeks after the end of therapy)
Time Frame: 24 weeks after the end of therapy
24 weeks after the end of therapy

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Proportion of patients with HCV RNA undetectable (defined as HCV RNA <15IU/ml)
Time Frame: at weeks 4, 12, 24 for genotype 2/3, and weeks 4, 12, 24 and 48 for non-genotype 2/3
at weeks 4, 12, 24 for genotype 2/3, and weeks 4, 12, 24 and 48 for non-genotype 2/3

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
