What is being measured

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

  1. The safety and tolerability as assessed by adverse events, vital signs, 12-lead electrocardiograms, echocardiograms (Cohorts 1 and 2 only), and laboratory assessments

    Measured: Up to 52 weeks

Secondary outcomes (8)
  1. The proportion of subjects who have an SVR at 4 weeks after the last planned dose of treatment (SVR4)

    Measured: 16 weeks

  2. The proportion of subjects who have an SVR at 12 weeks after the last planned dose of treatment (SVR12)

    Measured: 24 weeks

  3. The proportion of subjects who have an SVR at 24 weeks after the last planned dose of treatment (SVR24)

    Measured: 36 weeks

  4. The proportion of subjects who have virologic relapse

    Measured: Up to 52 weeks

  5. Viral kinetics, as determined at different time points by the proportion of subjects who achieve: -Undetectable HCV RNA -<LLOQ HCV RNA

    Measured: Up to 64 weeks

  6. The proportion of subjects who have virologic breakthrough

    as measured by on-treatment HCV RNA values

    Measured: Up to 52 weeks

  7. The proportion of subjects who achieve SVR12 by IL-28B genotype (CC versus non-CC)

    Measured: up to 28 weeks

  8. The amino acid sequence of the nonstructural (NS)5B protein in subjects who fail treatment

    Measured: Up to 60 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing VX-135 and ribavirin in people with Chronic Hepatitis C, run by Vertex Pharmaceuticals Incorporated at 6 sites in United States.

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 6 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 16 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

The safety and tolerability as assessed by adverse events, vital signs, 12-lead electrocardiograms, echocardiograms (Cohorts 1 and 2 only), and laboratory assessments (time frame: Up to 52 weeks). 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 16 Apr 2015.
