Pioglitazone vs. Placebo in Association With Pegylated Interferon and Ribavirin in HCV Patients With Insulin Resistance

Phase 3TerminatedNCT00927290

French National Agency for Research on AIDS and Viral Hepatitis40 enrolled

Overview

The purpose of this study is to test whether the correction of insulin resistance with pioglitazone, will improve the response to antiviral treatment.

In patients infected with genotypes 1, 4, 5 and 6, the response rate to antiviral therapy remains suboptimal (less than one in two patients have a sustained virological response), which justifies the search for strategies optimizing the results of antiviral therapy. Some factors associated with non response have been identified. Among the modifiable factors, numerous series have shown that insulin resistance adversely impacts the rate of sustained virological response. The aim of this study is to determine whether the pharmacological correction of insulin resistance through therapy with glitazones restores higher rates of viral eradication and to determine the impact on the kinetics of viral response. Patients will be randomized to receive pioglitazone or placebo starting 4 months before initiating pegylated interferon and ribavirin and continued throughout the whole antiviral treatment period.

Outcomes

Primary Outcomes

Decrease in the HOMA score below 2 after 4 months of treatment with pioglitazone or placebo(at W16). The efficiency is defined as a higher proportion of subjects with HOMA <2 in the pioglitazone group than in the group treated with placebo pioglitazone.

Time frame: W16

Secondary Outcomes

Kinetics of decrease in viral response to pegylated interferon. Early virological response rates. Rates of sustained virological response. Effect on steatosis

Time frame: EVR at W16 and W28 SVR at W88
