APPROACH Study: Quality of Life and Outcomes Assessment in Participants With Chronic Hepatitis C (CHC) Treated With Pegylated Interferon (PEG-IFN) Alfa-2a and Ribavirin

October 2, 2017 updated by: Hoffmann-La Roche

A Prospective Study of Peginterferon Alfa-2a and Ribavirin: Outcomes Assessment in Chronic Hepatitis C Patients

This multi-center, observational study will examine the clinical use and outcomes of pegylated interferon (PEG-IFN) alfa-2a and ribavirin combination (PEGASYS RBV) in participants with chronic hepatitis C (CHC). Study visits will be scheduled for baseline, 12, 24 and 48 weeks after baseline. An additional follow-up visit at week 72 will be required for participants with an HCV genotype other than 2 or 3. Quality of life data will be collected at baseline, and at each follow-up visit.

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 and older (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 Participants with Sustained Virologic Response (SVR)
Time Frame: Up to Week 72
Up to Week 72

Secondary Outcome Measures

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

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.

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.
