Detailed Description

Multicenter , Phase IV, open labeled, non-randomized trial to assess the Efficacy of Hansenula-derived recombinant pegylated interferon α 2a (Reiferon Retard® in treatment of naïve chronic hepatitis c virus Egyptian patients.

Each participant will be subject to thorough history taking, complete clinical examination, Biochemical laboratory and hematological tests, U/S imaging as well as histologic assessment of liver disease stage and severity to ensure his/her eligibility to be enrolled in the study according to predetermined inclusion and exclusion criteria .

Eligible subjects will be treated with Reiferon Retard® 160 µg once weekly by subcutaneous injection for 48 weeks treatment plus weight-based Ribavirin orally (1200 mg/kg daily for those > 75 Kg or 1000mg/Kg daily for those ≤ 75 kg in divided doses). HCV RNA will be assessed at week 12 of initiation of therapy to identify Early Virologic Response (EVR), at week 24 to identify breakthrough viremia, at week 48 to identify End of treatment Response (ETR), and at week 72 to identify Sustained Virologic Response (SVR).

All subjects will be followed up during the study as described in the table below (Section 4 Study Design).

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.

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 Virologic Response (SVR)
Time Frame: Assessed 24 weeks after the end of treatment

Sustained Virologic Response (SVR) is assessed by measurement of HCV RNA viral load 24 weeks after the end of Therapy.

SVR is defined as undetectable HCV RNA 24 weeks after the end of therapy.
Assessed 24 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.
Outcome Measure
Measure Description
Time Frame
Complete Early Virologic Response (cEVR)
Time Frame: At week 12 of therapy
Complete Early Virologic Response (cEVR)is defined as undetectable HCV RNA at week 12 of therapy.
At week 12 of therapy
End of Treatment Response (ETR)
Time Frame: at the end of therapy (48 weeks from initiation of therapy
ETR is defined as undetectable HCV RNA at the end of therapy (at week 48)
at the end of therapy (48 weeks from initiation of therapy
Safety
