What is being measured

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

  1. Percentage of Subjects With Undetectable Plasma Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) at Week 24 After the Completion of Treatment

    The plasma HCV RNA level was measured using Roche TaqMan HCV RNA assay. The lower limit of detection was 10 international units per milliliter (IU/mL).

    Measured: 24 weeks after the completion of treatment (up to Week 72)

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

    AE: any adverse change from the subject's baseline (pre-treatment) condition, including any adverse experience, abnormal recording or clinical laboratory assessment value which occurs during the course of the study, whether it is considered related to the study drug or not. An adverse event includes any newly occurring event or previous condition that has increased in severity or frequency since the administration of study drug. SAE: medical event or condition, which falls into any of the following categories, regardless of its relationship to the study drug: death, life threatening adverse experience, in-patient hospitalization/prolongation of hospitalization, persistent/significant disability or incapacity, congenital anomaly/birth defect, important medical event. "Study drug" includes all investigational agents (including placebo, if applicable) administered during the course of the study.

    Measured: Baseline through Week 48

Secondary outcomes (4)
  1. Percentage of Prior Relapsers With Undetectable HCV RNA

    Prior relapsers: subjects who had undetectable HCV RNA at the end of treatment in parent study but reverted to detectable levels of HCV RNA after stopping treatment in parent study were categorized as prior relapsers. Percentage of prior relapsers with undetectable HCV RNA 24 weeks after the completion of treatment in this study were presented. The plasma HCV RNA level was measured using Roche TaqMan HCV RNA assay. The lower limit of detection was 10 international units per milliliter (IU/mL).

    Measured: 24 weeks after the completion of treatment (up to Week 72)

  2. Percentage of Subjects With End of Treatment Response

    Subjects were considered to have an end of treatment response if they completed the assigned treatment regimen and had undetectable HCV RNA at end of treatment or prematurely discontinued the assigned treatment regimen and had undetectable HCV RNA at the time of discontinuation. The plasma HCV RNA level was measured using Roche TaqMan HCV RNA assay. The lower limit of detection was 10 international units per milliliter (IU/mL).

    Measured: End of treatment (up to Week 48)

  3. Percentage of Subjects With Undetectable HCV RNA at Week 48 After Completion of Treatment Among Subjects Who Completed Assigned Treatment

    The plasma HCV RNA level was measured using Roche TaqMan HCV RNA assay. The lower limit of detection was 10 international units per milliliter (IU/mL).

    Measured: 48 weeks after completion of treatment (up to Week 96)

  4. Cross Tabulation of Extended Rapid Viral Response (eRVR) and Sustained Viral Response (SVR) in With Prior Response

    Cross tabulation of number of subjects with eRVR/SVR status in present study was presented with respect to prior response status of subjects in parent studies. eRVR=undetectable HCV RNA at Week 4 and Week 12, SVR=undetectable HCV RNA at end of treatment (EOT) and at 24 weeks after last dose of study treatment without any confirmed detectable HCV RNA in between. Prior response=subjects were categorized into following categories based on their viral response in the parent study: Null Response (less than [<] 1-log10 decrease in HCV RNA at Week 4 or <2-log10 decrease in HCV RNA at Week 12), Partial Response (greater than [>] 2-log10 decrease in HCV RNA at Week 12, but detectable HCV RNA at Week 24), Viral Breakthrough (detectable HCV RNA during treatment after achieving undetectable HCV RNA), Relapse (undetectable HCV RNA at EOT but detectable HCV RNA during viral follow-up). Plasma HCV RNA level was measured using Roche TaqMan HCV RNA assay; lower limit of detection=10 IU/mL.

    Measured: Baseline up to Week 72

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Telaprevir, Ribavirin and Pegylated interferon alfa 2a in people with Hepatitis C, run by Vertex Pharmaceuticals Incorporated at 62 sites in 8 countries.

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 1 inclusion and 0 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 5 Aug 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 62 sites in United States, France, Germany, Canada, Netherlands and 3 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 25 Jul 2011). 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 Subjects With Undetectable Plasma Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) at Week 24 After the Completion of Treatment (time frame: 24 weeks after the completion of treatment (up to Week 72)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 5 Aug 2014.
