A Study Evaluating IL28B Polymorphism in Patients With HBeAg-Negative Chronic Hepatitis B Treated With Pegasys (Peginterferon Alfa-2a) in Study ML18253

March 10, 2017 updated by: Hoffmann-La Roche

Cross-sectional Multicenter Study Evaluating the IL28B Polymorphism in Patients With HBeAg-negative Chronic Hepatitis B Treated With Pegylated Interferon Alfa-2a in the Course of Peg.Be.Liver Study

This cross-sectional multicenter study will evaluate the IL28B polymorphism in patients with HBeAg-negative chronic hepatitis B treated with Pegasys (peginterferon alfa-2a) in the predecessor ML18253 study. The study consists of a single visit where eligible patients will undergo a blood test for IL28B genotyping, with a phone follow-up 7 days after the visit.

Study Overview

Status

Status

Conditions

Conditions

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

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 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 Viral Response (SVR) Defined as HBV DNA ≤ 2000 IU/ml at IL28B Genotype rs12979860 at End of Follow-up (EoF)
Time Frame: EoF, as defined in the predecessor study, was at 48 weeks after the end of treatment.

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.

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.
