A Study Evaluating Slow Response/Non-Rapid Response in Patients With Chronic Hepatitis C, Genotype 1, 2, 3 & 4 Treated With Pegasys (Peginterferon Alfa-2a) and Copegus (Ribavirin)

Phase 4
Completed
Conditions
Hepatitis C, Chronic
Interventions
Drug: peginterferon alfa-2a [Pegasys]
Drug: ribavirin [Copegus]
Registration Number
NCT01429792
Lead Sponsor
Hoffmann-La Roche
Brief Summary

This multi-center study will evaluate the viral response in patients with chronic hepatitis C, genotype 1, 2, 3 \& 4 on standard anti-viral treatment with Pegasys (peginterferon alfa-2a) and Copegus (ribavirin). Patients will receive weekly subcutaneous Pegasys plus daily oral Copegus for 24 weeks (genotype 2 \& 3) or 48 weeks (genotype 1 \& 4). Patients identified as slow responders/non-rapid virological responders will be eligible for an additional 24 weeks of treatment.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Rapid Virologic Response (RVR) at Week 4Week 4

The rate of participants with RVR was defined as negative HCV-RNA level at Week 4 of study treatment.

Percentage of Participants With Non-RVR and Undetectable HCV-RNA at Week 24Week 24

The rate of participants with non-RVR and undetectable HCV-RNA at Week 24 was defined as detectable HCV-RNA level at Week 4 of study treatment and undetectable HCV-RNA at Week 24 of study.

Percentage of Participants With Complete Early Virologic Response (cEVR) to Study TreatmentWeek 12

The rate of participants with a cEVR to study treatment was defined as negative HCV-RNA level at Week 12 of study treatment

Percentage of Participants With Partial Early Virological Response (pEVR) to Study TreatmentWeek 12

The rate of participants with pEVR to study treatment was defined as ≥ 2 log reduction in HCV-RNA level from baseline value to Week 12 of study treatment but with detectable HCV-RNA at Week 12.

Percentage of Participants With Undetectable HCV-RNA at End of Treatment Response (ETR) at Week 24Week 24

The rate of participants with undetectable HCV-RNA at ETR at Week 24 was defined as at least a 2-log decrement in HCV-RNA from the start of treatment, but with detectable HCV-RNA at Week 12 of study treatment and undetectable HCV-RNA at Week 24 of study treatment

Percentage of Participants Without a RVR (Non-RVR) at Week 4 of Standard TreatmentWeek 4

The rate of participants without a RVR (non-RVR) was defined as detectible HCV-RNA level at Week 4 of standard treatment.

Secondary Outcome Measures

Percentage of Participants With pEVR to Study Treatment at Week 12Week 12

The rate of participants with pEVR to study treatment was defined as ≥ 2 log reduction in HCV-RNA level from baseline value to Week 12 of study treatment but with detectable HCV-RNA at Week 12.

Percentge of Participants With a cEVR to Study Treatmen at Week 12 of Study TreatmentWeek 12

The rate of participants with a cEVR to study treatment was defined as negative HCV-RNA level at Week 12 of study treatment.

Percentage of Participants With Undetectable HCV-RNA at Week 24, But With Detectable HCV-RNA atWeek 12 and Undetectable HCV-RNA at Week 24Week 24

The rate of participants with undetectable HCV-RNA at ETR at Week 24 was defined as at least a 2-log decrement in HCV-RNA from the start of treatment, but with detectable HCV-RNA at Week 12 of study treatment and undetectable HCV-RNA at Week 24 of study treatment.
