<qa>  What is the new standard of care prior to HCV therapy for those who are insulin resistant?This study will demonstrate the efficacy of treating insulin resistance with rosiglitazone in CHC, genotype 1 patients who have failed previous treatment with pegylated interferon and ribavirin. Pre-treatment with rosiglitazone may become the new standard of care prior to HCV therapy for those patients who are insulin resistant, increasing their chance for achieving an SVR on interferon alfacon-1 combination therapy and decreasing the morbidity and mortality associated with chronic hepatitis C.
