2 Efficacy of HCV Protease Inhibitors in Co-Infected Patients Telaprevir + PegIFN/r Undetectable HCV RNA at week 12 –86% TP/r vs 33% placebo Undetectable HCV RNA at week 24 –74% TP/4 vs 55% placebo Boceprevir+ PegIFN/r Undetectable HCV RNA at week 12 –59.4% BOC+ P/r vs. 23.5% P/r Undetectable HCV RNA at week 24 –73.4% BOC+ P/r vs. 32.4% P/r Dieterich D et al.

10 The Role of Ribavirin in Treating HCV in Co-infected MSM In group 2, –Sustained virological response (SVR) rates were significantly higher for peg-IFN+RBV (31 of 33) peg-IFN mono-therapy (6 of 10) (94% vs 60%, respectively; p = 0.02). –SVR was significantly associated with Peg-IFN+RBV combination therapy (p = 0.037) and rapid virological response (p ) In group 1 –SVR was only significantly associated with rapid virological response (p ) Boesecke C. et al.
