An Observational Study of Pegasys (Peginterferon Alfa-2a) Plus Ribavirin Based Regimens in Patients With Chronic Hepatitis C With Previous Treatment Failure

September 14, 2016 updated by: Hoffmann-La Roche

Non-interventional, Observational Study on Retreatment of Chronic Hepatitis C Patients Previous Treatment Failure, Using Peginterferon Alfa-2a and Ribavirin Based Regimens

This prospective, national, multicenter, observational study will evaluate in routine clinical practice the efficacy and safety of re-treatment with Pegasys (peginterferon alfa-2a) plus ribavirin or regimens containing direct-acting antivirals in participants with chronic hepatitis C who failed previous treatment. Participants will be followed for the duration of their treatment (24, 48 or 72 weeks) and for 24 weeks of follow-up.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

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.

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

All

Sampling Method

Drug: Pegylated Interferon alfa-2a
Dosing was at the discretion of the investigator in accordance with local clinical practice and local labelling.
Other Names:

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
Sustained virological response (SVR) rate, defined as percentage of patients with HCV RNA <50 IU/mL at 24 weeks post completion of treatment (overall and stratified by prior treatment outcome: non-response and relapse)
Time Frame: approximately 3 years
approximately 3 years

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
Safety: Incidence of adverse events
Time Frame: approximately 3 years
approximately 3 years
Duration of treatment
Time Frame: approximately 3 years
approximately 3 years
Percentage of patients with rapid virological response (RVR), defined as HCV RNA <50 IU/mL at Week 4 (overall and stratified by prior treatment outcome: non-response and relapse)
Time Frame: approximately 3 years
approximately 3 years
Percentage of patients with early virological response (EVR), defined as HCV RNA <50 IU/mL or an at least 2-log drop from baseline in HCV RNA at Week 12, but with no RVR (overall and stratified by prior treatment outcome: non-response and relapse)
Time Frame: approximately 3 years
approximately 3 years
Percentage of patients with non-response/relapse/virological breakthrough/virological rebound
Time Frame: approximately 3 years
approximately 3 years
Time to safety-related dose reduction/treatment discontinuation of any of the treatment compounds
Time Frame: approximately 3 years
approximately 3 years

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.
