What is being measured

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

  1. Proportion of Subjects Achieving Undetectable HCV RNA at Week 12

    Measured: 12 weeks after first dose of study drug

Secondary outcomes (5)
  1. Proportion of Subjects Achieving Undetectable HCV RNA at Week 4 and Week 12

    number of subjects with undetectable HCV RNA

    Measured: 4 and 12 weeks after the first dose of study drug

  2. Proportion of Subjects Who Have Undetectable HCV RNA 12 Weeks (SVR12) and 24 Weeks (SVR24) After Last Planned Dose of Study Treatment

    Measured: 12 weeks after last dose of study drug

  3. Effect of Efavirenz-based (EFV) and Atazanavir-based (ATV/r) Highly Active Antiretroviral Therapy(HAART) on Telaprevir Exposure

    Measured: through 12 weeks after first dose of study drug

  4. Median Trough Plasma Concentration (Ctrough) Ratios of Efavirenz and Tenofovir (Part B Only, Subjects on EFV-based HAART)

    Ctrough ratio of HAART medication with telaprevir (test) and without telaprevir (reference)

    Measured: through 12 weeks after first dose of study drug

  5. Median Trough Plasma Concentration (Ctrough) Ratios of Atazanavir (ATZ), Ritonavir, and Tenofovir (Part B Only, Subjects on ATV-based HAART)

    Ctrough of HAART medication with telaprevir (test) and without telaprevir (reference)

    Measured: through 12 weeks after first dose of study drug

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing peginterferon alfa-2a, ribavirin (fixed dose) and ribavirin (weight-based dose) in people with Hepatitis C and HIV Infections, run by Vertex Pharmaceuticals Incorporated at 16 sites in 4 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 3 inclusion and 5 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 10 Oct 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 16 sites in United States, Germany, Spain, France. 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 10 Oct 2013). 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?

Proportion of Subjects Achieving Undetectable HCV RNA at Week 12 (time frame: 12 weeks after first dose of 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 NCT00983853, 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 10 Oct 2013.
