BACKGROUND
· Telaprevir (TVR, T) is an orally bioavailable, specifically targeted antiviral drug for hepatitis C virus (HCV) that potently and selectively inhibits the HCV NS3·4A protease.1,2
· TVR in combination with peginterferon alfa-2a and ribavirin (PR) has been studied in treatment-naïve patients and improved sustained virologic response (SVR) rates, compared with PR alone.3,4,5
· ADVANCE was a randomized, placebo-controlled, Phase 3 clinical trial that evaluated efficacy and safety of TVR in combination with PR in chronic HCV genotype 1-infected treatment-naïve patients.5
· ILLUMINATE was an open-label, randomized, non-inferiority Phase 3 clinical trial that evaluated efficacy and safety of 24 weeks of TVR-based treatment versus 48 weeks in chronic HCV genotype 1-infected treatment-naïve patients who achieved extended rapid virologic response (eRVR, undetectable HCV RNA at weeks 4 and 12).6
· In this retrospective pooled analysis, we investigated efficacy outcomes based on anemia and ribavirin dose reductions.
