About this study

Official title: A Randomized, Open-Label Study to Evaluate the Efficacy and Safety of ABT-450/Ritonavir/ABT-267 and ABT-333 Co-administered With and Without Ribavirin Compared to Telaprevir Co-administered With Pegylated Interferon α-2a and Ribavirin in Treatment-Naïve Adults With Chronic Hepatitis C Genotype 1 Virus Infection (MALACHITE I)

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.

Read the 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With Sustained Virologic Response 12 Weeks After Treatment (SVR12) - Primary Efficacy Analyses

    The percentage of participants with sustained virologic response (plasma Hepatitis C virus ribonucleic acid [HCV RNA] level less than the lower limit of quantitation [< LLOQ]) 12 weeks after the last dose of study drug.

    Measured: 12 weeks after the last actual dose of active study drug

Secondary outcomes (6)
  1. Mean Change From Baseline to the Final Treatment Visit in Short-Form 36 Version 2 Health Status Survey (SF-36V2) Mental Component Summary (MCS)

    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).

    Measured: 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

  2. Mean Change From Baseline to the Final Treatment Visit in SF-36V2 Physical Component Summary (PCS)

    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).

    Measured: 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

  3. Percentage of Participants With SVR12 - Secondary Efficacy Analyses

    The percentage of participants with sustained virologic response (plasma HCV RNA level < LLOQ) 12 weeks after the last dose of study drug.

    Measured: 12 weeks after the last actual dose of active study drug

  4. Percentage of Participants With Virologic Failure During Treatment

    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.

    Measured: 12 weeks for Arms A, C and D and 24 weeks or 48 weeks for Arms B and E

  5. Percentage of Participants With Post-treatment Relapse

    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.

    Measured: Within 24 weeks post treatment

  6. Percentage of Participants With Sustained Virologic Response 24 Weeks After Treatment (SVR24)

    The percentage of participants with sustained virologic response (plasma HCV RNA level < LLOQ) 24 weeks after the last dose of study drug.

    Measured: 24 weeks after the last actual dose of active study drug

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing ABT-450/r/ABT-267, ABT-333, Ribavirin and Telaprevir in people with Chronic Hepatitis C Infection, run by AbbVie.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 22 Feb 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants With Sustained Virologic Response 12 Weeks After Treatment (SVR12) - Primary Efficacy Analyses (time frame: 12 weeks after the last actual dose of active study drug). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01854697, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Jun 2018.
