A Study to Evaluate the Efficacy and Safety of Three Experimental Drugs Compared With Telaprevir (a Licensed Product) in People With Hepatitis C Virus Infection Who Have Not Had Treatment Before
- Conditions
- Chronic Hepatitis C Infection
- Interventions
- Drug: ABT-450/r/ABT-267, ABT-333Drug: Pegylated Interferon alpha 2-a (PegIFN)
- Registration Number
- NCT01854697
- Lead Sponsor
- AbbVie
- Brief Summary
This is a study to evaluate the efficacy and safety of three experimental drugs compared with telaprevir (a licensed product) in people with hepatitis C virus infection who have not had treatment before.
- Detailed Description
The primary purpose of this study is to demonstrate that treatment with ABT-450/ritonavir (r)/ABT-267 and ABT-333 administered with or without ribavirin (RBV) has non-inferior efficacy compared to treatment with telaprevir and pegylated interferon alpha-2a (pegIFN) and RBV and to compare the safety of these regimens in treatment-naive hepatitis C virus (HCV) genotype (GT) 1a- and 1b-infected adults.

- Secondary Outcome Measures
Name Time Method Percentage of Participants With SVR12 - Secondary Efficacy Analyses 12 weeks after the last actual dose of active study drug The percentage of participants with sustained virologic response (plasma HCV RNA level \< LLOQ) 12 weeks after the last dose of study drug.
Mean Change From Baseline to the Final Treatment Visit in Short-Form 36 Version 2 Health Status Survey (SF-36V2) Mental Component Summary (MCS) From Day 1 of treatment up to 12 weeks for Arms A, C and D and up to 24 or 48 weeks for Arms B and E SF-36V2 is a generic 36-item questionnaire measuring health-related quality of life (HRQoL) covering 2 summary measures: physical component summary (PCS) and MCS; it consists of 8 subscales. The MCS is represented by 4 subscales: vitality, social function, role limitations due to emotional problems, and mental health. Participants self-report on items in a subscale that have choices per item. Scoring is done for both MCS subscale scores and summary scores; for each, the range is 0 (worst HRQoL) to 100 (best HRQoL).
Mean Change From Baseline to the Final Treatment Visit in SF-36V2 Physical Component Summary (PCS) From Day 1 of treatment up to 12 weeks for Arms A, C and D and up to 24 or 48 weeks for Arms B and E SF-36V2 is a generic 36-item questionnaire measuring HRQoL covering 2 summary measures: PCS and MCS; it consists of 8 subscales. The PCS is represented by 4 subscales: physical function, role limitations due to physical problems, bodily pain, and general health perception. Participants self-report on items in a subscale that have choices per item. Scoring is done for both PCS subscale scores and summary scores; for each, the range is 0 (worst HRQoL) to 100 (best HRQoL).
Percentage of Participants With Virologic Failure During Treatment 12 weeks for Arms A, C and D and 24 weeks or 48 weeks for Arms B and E Participants in Arms A, C or D demonstrating any of the following were considered virologic failures and discontinued therapy:
* Confirmed increase from nadir in HCV RNA (defined as 2 consecutive HCV RNA measurements of \>1 log10 IU/mL above nadir) at any time point during treatment
* Failure to achieve HCV RNA \< LLOQ by Week 6 or
* Confirmed HCV RNA ≥ LLOQ (defined as 2 consecutive HCV RNA measurements ≥ LLOQ) at any point after HCV RNA \< LLOQ during treatment after HCV RNA \< LLOQ.
Participants in Arms B and E followed virologic stopping criteria described in the TPV Summary of Product Characteristics; they were considered virologic failures and discontinued therapy as follows:
* HCV RNA \> 1000 IU/mL at Week 4 to Week 12, discontinue TPV and pegIFN and RBV
* HCV RNA \> 1000 IU/mL at Week 12, discontinue pegIFN and RBV
* Confirmed HCV RNA \> lower limit of detection (LLOD) at Week 24, discontinue pegIFN and RBV
* Confirmed HCV RNA \> LLOD at Week 36, discontinue pegIFN and RBV.Percentage of Participants With Post-treatment Relapse Within 24 weeks post treatment Hepatitis C virus (HCV) ribonucleic acid (RNA) confirmed greater than or equal to the lower limit of quantification (LLOQ) between the end of treatment and 24 weeks post treatment among participants completing treatment and with HCV RNA less than the LLOQ at the end of treatment.
Percentage of Participants With Sustained Virologic Response 24 Weeks After Treatment (SVR24) 24 weeks after the last actual dose of active study drug The percentage of participants with sustained virologic response (plasma HCV RNA level \< LLOQ) 24 weeks after the last dose of study drug.
