E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To provide access to a telaprevir-based treatment to subjects enrolled in the Peg-IFN-alfa-2a plus ribavirin Control Group (Group A) of Studies VX06-950-106, VX05-950-104 or VX05-950-104EU who stopped treatment due to inadequate response to treatment or who relapsed after treatment. Safety, tolerability, and HCV RNA levels will be collected.
Study VX06-950-106 was submitted under a separate CTA in Germany and the Netherlands (EudraCT # 2006-004665-33), Study VX05-950-104EU was submitted under a separate CTA to Germany, UK, France and Austria (EudraCT #2006-000828-14). Study VX05-950-104 is being conducted in the United States. |

E.3 | Principal inclusion criteria |
- Subjects randomized in the Peg-IFN-alfa plus ribavirin control arm (Group A) of Study VX06-950-106, study VX05-950-104 or Study VX05-950-104EU are eligible to participate. Subjects from Study VX06-950-106 must enter the study only after week 24 and within 72 weeks of taking their first dose of study drug in the parent study. subjects from study VX05-950-104 and VX05-950-104EU should enter this study as soon as possible and within 76 weeks of taking their first dose of study drug in the parent study.
- Subjects must have discontinued treatment in the parent study based on the following criteria: All subjects: • Viral breakthrough between Week 4 and Week 24. Subjects discontinued study treatment if, on 2 consecutive occasions, the results of HCV RNA testing indicated viral breakthrough. Viral breakthrough is defined as (1) an increase in HCV RNA of >1 log10 compared to the lowest recorded on-treatment value or (2) an HCV RNA level of >100 IU/mL in a subject who had undetectable HCV RNA at a prior time point. • Week 12 (EVR) Nonresponder, defined as not having achieved an early viral response (EVR, a ≥2 log10 reduction from baseline in HCV RNA). • Week 24 Nonresponder, defined as subjects who had detectable HCV RNA at Week 24. • Week 26 to Week 48 Nonresponder; defined as subjects who had detectable HCV RNA between Weeks 26 and 48. • Subjects who had detectable HCV RNA during the 24-week post-treatment period. VX06-950-106 subjects only: Week 4 Nonresponder, defined as not having a ≥1-log10 decrease from baseline in HCV RNA. - The screening visit laboratory values must be within the central laboratory reference ranges outlined in the protocol. - 3. Subjects must agree to use 2 non-hormonal methods of contraception that are highly effective, with one or both being barrier methods (for example a condom in combination with an IUD, or a condom in combination with a diaphragm and spermicide). It is uncertain how much the effectiveness of hormonal contraceptives may be reduced whilst taking telaprevir, therefore, female patients who are already taking a hormonal contraceptive may continue to use that method, but also use two non-hormonal methods, as described above, for the duration of telaprevir treatment and for two months after the last dose. Once treatment with telaprevir is completed, subjects must continue to use 2 efficient methods of contraception for an additional month, (i.e., total of 90 days including 2 non-hormonal methods for the first 2 months of those 90 days), and in line with RBV’s package insert, until 7 months after the last dose of RBV have elapsed. Female subjects and female partners of male subjects must use the same precautions. Male subjects must not father a child while on study and for 24 weeks after the last dose of the study medication.
Female subjects of childbearing potential must have a negative pregnancy test at all visits before the first dose and during the dosing period. (Note: For female partners of male subjects, pregnancy testing cannot be mandated because the partners are not study participants. However, monthly pregnancy testing until 7 months after the male’s last dose of RBV is strongly recommended, in accordance with the product labeling for RBV.)
- Subjects must be willing to refrain from the concomitant use of any medications, substances or foods noted in Section 18 of the protocol. - Subjects must be able to read and understand the Informed Consent Form (ICF) and willing to sign the ICF and abide by the study restrictions. - Subjects must agree not to participate in other clinical studies for the duration of their participation in this trial. |
|
E.4 | Principal exclusion criteria |
- Subjects who discontinued prior Peg-IFN or RBV for adverse events or for any other reason other than failure to respond to therapy and for whom repeated treatment would be inappropriate. - Women who are pregnant or breast-feeding. - Male partners of women who are pregnant or breast-feeding. - Subjects who have taken any of the prohibited medications identified in Section 18 of the protocol within 30 days of Day 1. |
|
E.5 End points |
E.5.1 | Primary end point(s) |
Primary Endpoint: - Plasma HCV RNA response to telaprevir treatment
Secondary endpoints: - Adverse events and clinical laboratory assessments, including ALT and other liver function tests. - Genotypic and phenotypic analyses of the NS3•4A HCV region. - Pharmacokinetic assessments of telaprevir in cases with rash. |
