Summary

The main objective of antiviral therapy of patients with chronic hepatitis C (CHC) is the sustained elimination of the hepatitis C virus (HCV). The standard of care (SOC) is peginterferon alfa-2a/-2b with ribavirin for 48 weeks or 24 weeks according to HCV genotype.

However, this approach is not sufficient to substantially improve the sustained virologic response (SVR) rates. Therefore, new therapies are needed to treat patients with hepatitis C virus (HCV) infection. Nitazoxanide (NTZ), originally used to treat cryptosporidium parvum infection, recently was shown to have an unexpected antiviral activity in the HCV replicon system and in chronically infected patients.

The aim of this work is to study impact of nitazoxanide therapy in addition to peginterferon/ribavirin combination on virologic responses in patients with chronic hepatitis C genotype 4.

Patients will be enrolled in this study and will be randomly assigned in a 1:1 ratio into 2 groups:

Group A: comprises 100 CHC patients who will receive the standard of care treatment, peginterferon-alf 2a plus weight-based ribavirin for 48 weeks.

Group B: comprises 100 CHC patients who will receive nitazoxanide monotherapy at a dose of 500 mg twice daily for 12 weeks as a lead-in phase followed by triple therapy, nitazoxanide 500 mg twice daily plus peginterferon alfa-2a, and weight-based ribavirin for 48 weeks.

Data will be collected and statistical analysis will be done comparing the groups regarding response to antiviral therapy. Final results will be discussed and compared to similar studies published in peer reviewed journals and international conferences.

Interventions

DRUG

Placebo

Group A: comprises 100 CHC patients who will receive placebo twice daily with food for an average of 12 weeks as a part of monotherapy lead-in phase followed by triple therapy, nitazoxanide 500 mg twice daily plus peginterferon alfa-2a (once weekly), and weight-based ribavirin (1000-1200 mg daily) for 48 weeks.

DRUG

Nitazoxanide

• Group B: comprises 100 chronic hepatitis patients who will receive oral Nitazoxanide 500 mg twice daily with food for an average of 12 weeks followed by the standard of care treatment, peginterferon Alfa 2a once weekly and weight-based ribavirin 1000 or 1200 mg/day (based on body weight \< 75 kg or ≥ 75 kg, respectively) in divided doses plus placebo twice daily for 48 weeks.
