2%) undergoing boceprevir triple therapy achieved an EVR (59.5% male, 32.9% > 50 years, 61.8% with baseline viral load > 400.000 IU/mL) while 64 patients (28.8%) did not (48.4% male, 48.4% > 50 years, 82.8% with baseline viral load > 400.000 FK866 nmr IU/mL). As shown in the table pts with normal gamma-GT values had a higher virologic response >1log10 to PegIFN/RBV lead-in at the end of TW4. In addition there was a significant higher virologic response

in pts who achieved EVR. Only 1 patient (0.8%) with EVR had HCV-RNA levels > 100 IU/mL thereby fulfilling TW12 stopping rules in contrast to 9 pts (9.2%) without EVR. A better virologic response was found at TW24 and at the end of treatment (EOT) with EOT response rates of 94.9% and 65.9% in pts with and without EVR. Until yet Dabrafenib documented follow-up data were available from 72 pts with EOT response: In the subgroup of pts with EVR, 57/63 (90.5%) achieved SVR and 4 pts had a documented relapse (6.3%) while 9 pts without EVR but EOT response achieved SVR. Conclusions: Approximately 70% of treatment-naïve patients with HCV G1 infection undergoing triple therapy with boceprevir in German real-life experience an EVR which allow shortage of triple therapy to 24 weeks. In addition, achieving EVR is associated with a high

EOT response rate > 90%. The higher virologic response at the end of lead-in suggests a higher sensitivity to PegIFN/RBV backbone in pts who achieve EVR.

Compared to HCV mono-infected patients, co-infected patients experience decreased ability to spontaneously clear HCV, accelerated liver fibrosis progression leading to earlier liver failure, and higher risk of death.
