Clinical Trial Summary

Objectives: 1. Primary objective: To Evaluate the rate of sustained virological response (SVR) of pegylated interferon alfa-2b (Peg-IFN) plus ribavirin (RBV) plus nitazoxanide (NTZ) in patients coinfected by HIV and HCV genotype 4 (HCV-4), never treated before (naïve) and with a treatment failure to a standard therapy with Peg-IFN plus RBV (experienced), and to compare it with the rate of SVR of these patients with Peg-IFN plus RBV is a historical cohort. 2. Secondary objectives: In naive, as well as in experienced patients: a) To evaluate the virological activity at weeks 4 and 12 after starting the combination of Peg-IFN plus RBV plus NTZ in HIV/HCV-4-coinfected patients. b) To analyze the safety of Peg-IFN plus RBV plus NTZ in HIV/HCV-4-coinfected patients.

Design: Pilot clinical trial without control to evaluate efficacy and safety (phase II).

Patients: Individuals with HIV infection and with confirmed chronic HCV infection.

Treatment: NTZ 500 mg every 12 hours during 4 weeks, followed by NTZ 500 mg every 12 hours plus Peg-IFN plus weigh-adjusted RBV for 48 weeks. Total duration of therapy: 52 weeks.

Primary variable: The proportion of patients with HCV RNA ≤10 IU/ml 24 weeks after finishing the programmed length of treatment.

Secondary variables: 1. The frequency of individuals with HCV RNA ≤10 IU/ml 12 weeks after finishing the programmed length of treatment. 2. The proportion of patients with HCV RNA ≤10 IU/ml at 4 and 12 weeks after adding PegIFN plus RBV to NTZ. 3. The frequency of severe adverse events.


Clinical Trial Description

Main Objective To evaluate the SVR rate of treatment with Peg-IFN alfa-2b plus RBV and NTZ in patients coinfected with HIV and HCV genotype 4, both never exposed to therapy against HCV or who failed a previous treatment with Peg-IFN plus RBV, and to compare with the SVR rate obtained in patients with Peg-IFN plus RBV in a historical cohort.

Secondary objectives: In naive, as well as in experienced patients:

1. To evaluate the virological activity at weeks 4 and 12 after starting the combination of Peg-IFN plus RBV plus NTZ in HIV/HCV-4-coinfected patients.

2. To analyze the safety of Peg-IFN plus RBV plus NTZ in HIV/HCV-4-coinfected patients.

Design Single arm pilot clinical trial to evaluate safety and efficacy (phase II).

Disease or disorder under study Coinfection with HIV and HCV genotype 4.

Drugs under study Nitazoxanide 500 mg every 12 hours for 4 weeks followed by nitazoxanide 500 mg every 12 hours plus pegylated interferon alfa-2b 1.5 mcg/kg/week and weight-adjusted ribavirin for 48 weeks.

Study Population and total number of subjects Patients infected with HIV-1 with chronic HCV genotype 4 who meet the selection criteria.

Number of patients included in the study: 45. ;
