Chronic Hepatitis C Treatment by Pegylated Interferon and Ribavirin in Naive Egyptian Patients (ANRS 1211)
- Conditions
- Chronic Hepatitis C
- Registration Number
- NCT00158496
- Lead Sponsor
- French National Agency for Research on AIDS and Viral Hepatitis
- Brief Summary
Chronic hepatitis C is a liver disease related to a virus: hepatitis C virus (HCV). The type of HCV present in Egypt (genotype 4), has the reputation to respond poorly to Interferon treatment at the chronic stage. Pegylated Interferon is a new form of Interferon that stays in the body for longer time and allows the patient to take less injection per week. It has proved to be more effective than standard Interferon. The combination of two drugs, Interferon and Ribavirin, is considered to be the best treatment available for chronic hepatitis C.
- Detailed Description
Egypt is the country with the highest HCV prevalence worldwide, and the number of infected Egyptians is estimated around 8 million. The HCV genotype circulating in Egypt is genotype 4. This genotype has the reputation, based on the few available data, to respond poorly to treatment. This study will estimate the safety and efficacy of the combination of peg-IFNα-2a plus Ribavirin, in Egyptian patients with chronic hepatitis C. This treatment has been chosen based on its better expected efficacy compared to pegylated interferon alone.
The primary objective of the study is to assess the efficacy and tolerance of the combination of pegylated interferon (peg-IFNα-2a) plus ribavirin in Egyptian patients with chronic hepatitis C and with no prior treatment for HCV.
Methods: Open trial. Follow-up duration: 72 weeks. Enrolment duration: 18 months. Total trial duration: 3 years and a half, including trial analysis (carried out in the 6 months following the follow-up completion of the last patient). Total number of patients: 100. Precision around the expected efficacy rate (40% in intention-to-treat analysis): 9.6%.
Treatment strategy: Peg-IFNα-2a 180microg/week for 48 weeks, Ribavirin at least 11 mg/kg/day for 48 weeks Main inclusion criteria: HCV RNA positive by PCR; METAVIR score : \>A2 and \>= F1 or \>= A1 and \> F2; ALAT over 1.5\*N; no prior treatment with IFNalpha, PEG-IFNalpha and ribavirin Main exclusion criteria : Liver disease other than hepatitis C; advanced liver disease; negative HCV RNA.
Patient from a cohort follow-up conducted in a village in rural Egypt with High HCV prevalence (Menoufia governorate) will be proposed to participate in the trial. Pre-enrolment investigations, liver biopsy, and patients follow-up will be carried out at a local hospital. Blood test analyses will be carried out under the responsibility of Hepatitis Virology Reference Laboratory at the National Hepatology and Tropical Medicine Institute, Cairo; trial monitoring will be carried out by the Department of Community Medicine of Ain Shams; methodological assistance from the "Unite des Maladies Emergentes" at Pasteur Institute and INSERM U444, Paris.
Treatment for patients with HCV RNA by qualitative PCR still positive after 24 weeks of the combination Peg-IFNα-2a with ribavirin, will be stopped.
