August 9, 2011 updated by: Casa Sollievo della Sofferenza IRCCS

Multicenter Study on Efficacy of New Therapeutic Schedules With Peg-Interferon alpha2b and Ribavirin in Patients With Genotype 3 Chronic HCV( Hepatitis C Virus) Infection

The study aimed at evaluating whether current 24 weeks length of combination treatment is appropriate or not for patients with HCV genotype 3 infection.

Study Overview

Status

Status

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

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

Patients are randomized to standard length of treatment or to a variable duration: 12 weeks for patients with undetectable HCVRNA at week 4 or 24 or 36 weeks for those with detectable HCV RNA at week 4.

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

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
No Intervention: A1. standard duration
Patients were randomly assigned in a 1:1 ratio to two treatment arms. In the standard treatment group (A1), patients were treated for 24 weeks irrespective of the HCV RNA status at week 4 with Peg-interferon alfa-2b at a dose of 1.5 mcg per kilogram of body weight weekly in combination with oral ribavirin administered at a dose of 1000 mg/day for patients with a weight <75 kg or 1200 mg/day for those with a weight of ≥75 kg. Patients enrolled in Arm A1 will be treated for standard 24 weeks duration of treatment with standard dosages of PegInterferon alpha 2b and weight-based dosages of ribavirin.
Experimental: B 1 I or II
In the variable treatment group, patients with a virologic response at week 4 will receive treatment for 12 weeks and those without a virologic response at 4 weeks treatment for 36 weeks. Patients without RVR will be treated for 24 or 36 weeks and labelled (B1I) or (B1II, respectively Intervention: different durations of treatment for patients without RVR
Drug: Peg Interferon alpha2b + Ribavirin

B 1 I or II: Experimental

variable duration of treatment group according with RVR. In case of RVR present patients will be treated for 12 weeks. Patients without RVR will be treated for 24 (B1I) or 36 (B1II)weeks: different duration of treatment for patients without RVR

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
Measure Description
Time Frame
Sustained virological response (SVR)
Time Frame: 6 months after the end of treatment
The primary measure of efficacy will be HCV RNA not detectable in the serum 24 weeks after the end of therapy (SVR). In addition, virological response at the end of treatment and relapse rates will be calculated for each groups. Two analyses will be performed: 1) intention-to-treat analysis; 2) per-protocol analysis.
6 months after the end of treatment

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.
