Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is an open-label (all people know the identity of the intervention), multicenter study in genotype 1 chronic HCV infected liver transplant patients who will be treated for 12 weeks with telaprevir 750 mg every 8 hours given in combination with Peg-IFN-alfa-2a and ribavirin followed by 36 weeks of treatment with Peg-IFN-alfa-2a and ribavirin alone. The total treatment duration will be 48 weeks. Safety will be evaluated throughout the study and will include evaluations of adverse events, clinical laboratory tests, electrocardiogram, vital signs, and physical examination.

Phase

Phase

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No
