PHOENIX Study - A Study of PEGASYS (Peginterferon Alfa-2a (40KD)) and COPEGUS (Ribavirin) Administered After Liver Transplantation for Hepatitis C.

Phase 4
Completed
Conditions
Hepatitis C, Chronic
Interventions
Drug: peginterferon alfa-2a [Pegasys]
Registration Number
NCT00087633
Lead Sponsor
Hoffmann-La Roche
Brief Summary

This 2-arm study was designed to evaluate the efficacy, safety, and tolerability of prophylactic PEGASYS plus COPEGUS after liver transplantation for hepatitis C, compared to initiation of antiviral therapy at the time of clinical recurrence of hepatitis C infection. The anticipated time on study treatment was 3-12 months, and the target sample size was 100-500 individuals.

Primary Outcome Measures
NameTimeMethod
Percentage of Patients With Histologically-confirmed Recurrence of Hepatitis C Virus (HCV)120 weeks postrandomization

Histologically-confirmed recurrence of HCV defined as Batts-Ludwig inflammation grade ≥3 and/or fibrosis stage ≥2.

Inflammation(Grade): 0 No Activity,1 Minimal,2 Mild,3 Moderate,4 Severe.

Fibrosis (Stage): 0 No fibrosis, Normal; 1 Portal fibrosis; 2 Periportal fibrosis or rare portal septa; 3 Septal fibrosis, Fibrous septa with architectural distortion, no obvious cirrhosis; 4 Cirrhosis.

Secondary Outcome Measures
NameTimeMethod
Summary of Virologic ResponseAfter 4, 12, 24 and 48 weeks of therapy, and 24 weeks of follow-up

Rapid virologic responder (RVR): undetectable HCV-RNA at Week 4; complete early virologic responder (cEVR): undetectable HCV-RNA at Week 12; partial early virologic responder (pEVR): ≥2 log10 drop from baseline in HCV-RNA but positive at Week 12; early virologic responder (EVR): undetectable HCV-RNA or ≥2 log10 drop from baseline in HCV-RNA at Week 12; 24 weeks negative: undetectable HCV-RNA at Week 24; 48 weeks negative: undetectable HCV-RNA at Week 48; sustained virologic response (SVR): undetectable HCV-RNA at 24 weeks after the end of treatment.
