January 27, 2017 updated by: Trek Therapeutics, PBC

Phase 2a, Randomized, Double-Blind Study to Investigate the Safety and Efficacy of Faldaprevir in Combination With Ribavirin and TD-6450 for 12 Weeks in Treatment-Naive Patients Chronically Infected With Genotype 4 Hepatitis C Virus

Phase 2a study designed to assess the safety, efficacy, and pharmacokinetics of Faldaprevir and TD-6450 in combination with Ribavirin for a 12-week treatment duration in treatment-naïve participants with genotype 4 hepatitis C virus (HCV) infection.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

A study to evaluate the safety and effect of treatment with experimental antiviral drugs in combination with ribavirin in treatment-naïve participants with genotype 4 hepatitis C infection. The study will test the safety and effects of this alternative treatment for up to 12 weeks. Secondary objectives of this study are to determine the pharmacokinetics of the study drugs when co-administered, and to evaluate HCV RNA kinetics during treatment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Percentage of subjects achieving 12-week sustained virologic response following treatment with 2 direct acting anti-virals and ribavirin in Genotype 4 Hepatitis C infected adults
Time Frame: Post Treatment Week 12
Post Treatment Week 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Percentage of subjects with virologic response at Week 12 (HCV RNA less than lower limit of quantitation at end of therapy with Faldaprevir plus TD-6450 plus ribavirin)
Time Frame: Week 12
Week 12
Percentage of subjects with virologic response 2, 4 and 8 weeks after treatment completion (HCV RNA less than lower limit of quantitation at 2, 4 and 8 weeks after end of therapy with Faldaprevir plus TD-6450 plus ribavirin)
Time Frame: Post Treatment Weeks 2 to 8
Post Treatment Weeks 2 to 8

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
October 1, 2015

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
