The PROVE3 trial is a partially double blinded, randomized, Phase 2 research study of an investigational drug, Telaprevir (VX-950) or Placebo, with Pegylated Interferon Alfa 2a (Peg-IFN-alfa-2a, Pegasys«), and Ribavirin (RBV, Copegus«) in people with genotype 1 hepatitis C who have not achieved a Sustained Viral Response (SVR) with a previous treatment of interferon therapy.

Clinical Details

Official title: A Phase 2 Study of Telaprevir (VX-950) in Combination With Peginterferon Alfa-2a (Pegasys«), and Ribavirin (Copegus«) in Subjects With Genotype 1 Hepatitis C Who Have Not Achieved Sustained Viral Response With a Prior Course of Interferon Based Therapy

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Percentage of Subjects With Undetectable Plasma Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) at Week 24 After the Completion of Study Drug Dosing

Secondary outcome:

Percentage of Subjects With Undetectable Plasma HCV RNA at Completion of Study Drug Dosing

Percentage of Subjects With Undetectable Plasma HCV RNA

Number of Subjects With Adverse Events (AEs) and Serious Adverse Events (SAEs)

Number of Subjects With Viral Relapse

Maximum (Cmax), Minimum (Cmin) and Average (Cavg) Plasma Concentration of Telaprevir


Minimum age: 18 Years. Maximum age: 70 Years. Gender(s): Both.


Inclusion Criteria:
