Simeprevir + PEG + Ribavirin for HCV-HIV CoinfectionStudy C212: Study Features
C212 Trial: Features Design: Open-label, phase 3, trial evaluating simeprevir + PEG + RBV in
HCV-HIV and GT 1 (treatment naïve and experienced) Setting: 39 sites in 7 countries Entry Criteria
- HIV coinfection; HCV genotype 1- Treatment naïve or treatment experienced- Group 1: HCV treatment-naïve or prior relapse- Group 2: Prior partial or null response or cirrhosis- CD4 ≥ 200 if on stable ARV therapy; CD4 ≥ 500 if no ARV therapy- Stable antiretroviral therapy = HIV RNA < 50 copies/ml > 8 weeks
Patient Characteristics- N = 106 HCV-HIV coinfected patients- Race: white (82%); black (14%)- Baseline Median CD4 (cells/mm3): 629 cells/mm3
Primary End-Points: Efficacy (SVR12), safety, and impact on HIV

Simeprevir + PEG + Ribavirin for HCV-HIV CoinfectionStudy C212: Conclusions
Conclusions: “Simeprevir was generally well tolerated with safety similar to that observed in HCV-monoinfected patients and high SVR12 rates in HCV treatment-naive patients, prior relapsers, prior partial responders, and prior null responders with HIV-1 coinfection.”
