Hansenula-derived Pegylated Interferon in Treatment of Patients With Chronic Hepatitis C (HAPIC)
Efficacy and Safety of a Hansenula-derived Pegylated Interferon α2a (Reiferon Retard®) in Treatment of Patients With Chronic Hepatitis C Virus Infection: A National Multi-center Phase IV Open Label Non-Randomized Trial
It is a multi-center study of the efficacy of a new Pegylated Hansenula-derived recombinant interferon α 2a (Reiferon Retard® 160 µg once weekly in combination with ribavirin in treatment of Egyptian patients with chronic hepatitis C for 48 weeks.
hepatitis C virus (HCV) viral load will be assessed during therapy at weeks 12, 24 and end of treatment, as well as 24 weeks after therapy is completed.
Study Overview
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).

Primary Outcome Measures
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
