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

This study has been completed.

Hoffmann-La Roche Identifier:
First received: July 12, 2004
Last updated: December 22, 2010
Last verified: December 2010
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.

Condition Intervention Phase
Hepatitis C, Chronic Drug: peginterferon alfa-2a [Pegasys] Drug: Copegus Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Randomized, Open-label Study of Prophylactic Administration of PEGASYS Plus Ribavirin After Liver Transplantation on Hepatitis C Recurrence in Patients With Hepatitis C

Further study details as provided by Hoffmann-La Roche:

Primary Outcome Measures:
  • Percentage of Patients With Histologically-confirmed Recurrence of Hepatitis C Virus (HCV) [ Time Frame: 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:
  • Summary of Virologic Response [ Time Frame: After 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.
