  Purpose

To provide access to a telaprevir-based treatment to subjects of the Control Group of Study VX06-950-106, VX05-950-104, and VX05-950-104EU who stopped treatment due to inadequate response to treatment. Safety, tolerability, and HCV RNA levels will be collected.

Primary Purpose: Treatment
Official Title: A Phase 2 Rollover Protocol of Telaprevir (VX-950) in Combination With Peginterferon Alfa-2a (Pegasys®) and Ribavirin (Copegus®) in Subjects Enrolled in the Control Group (Group A) of Study VX06-950-106, VX05-950-104 and VX05-950-104EU Who Did Not Achieve or Maintain an Undetectable HCV RNA Level Through Sustained Viral Response

Primary Outcome Measures:
  • Proportion of Subjects With Undetectable HCV RNA [ Time Frame: 24 weeks after the completion of treatment ] [ Designated as safety issue: No ]
    Proportion of Subjects with SVR24 (undetectable HCV RNA 24 weeks after the completion of treatment)

  • Adverse Events and Clinical Laboratory Assessments [ Time Frame: Week 48 ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Proportion of Subjects With Undetectable HCV RNA; Subset Analysis by Prior Null Response, Prior Partial Response, Prior Viral Breakthrough, and Prior Relapse [ Time Frame: 24 weeks after the completion of treatment ] [ Designated as safety issue: No ]
    Proportion of subjects with SVR24 (undetectable HCV RNA 24 weeks after the completion of treatment) in prior relapsers

  • Proportion of Subjects With Undetectable HCV RNA; Subset Analysis by Prior Null Response, Prior Partial Response, Prior Viral Breakthrough, and Prior Relapse [ Time Frame: at the end of treatment ] [ Designated as safety issue: No ]
    Proportion of Subjects with End of Treatment Response (undetectable HCV RNA at end of treatment), overall

  • Proportion of Subjects With Undetectable HCV RNA; Subset Analysis by Prior Null Response, Prior Partial Response, Prior Viral Breakthrough, and Prior Relapse [ Time Frame: 48 weeks after completion of treatment ] [ Designated as safety issue: No ]
    Proportion of Subjects with SVR48 among Subjects Completing Assigned Treatment, Overall

  • Cross Tabulation of eRVR and SVR Responses in Study 107 With Prior Null Response, Prior Partial Response, Prior Viral Breakthrough, and Prior Relapse [ Time Frame: throughout study ] [ Designated as safety issue: No ]
    Number of subjects who achieved eRVR and/or SVR24
