3. High SVR Rates in HCV/HIV-1 Co-Infected Patients Regardless of Baseline Characteristics | IAS 2015 | 21 July 2015 3 Co-infection with HCV occurs in 20 – 40% of persons living with HIV HCV/HIV co-infection is associated with more rapid liver disease progression, non-hepatic organ dysfunction, and increased overall mortality compared to HCV mono-infected patients 1 In the era of potent HIV ART, liver-related disease is a leading cause of death in co-infected patients, 2,3 thus, guidelines indicate that co- infected patients should be prioritized for HCV treatment 4,5 Recommendations indicate that new interferon-free HCV direct-acting antiviral (DAA) regimens should be used in co-infected patients as if they were HCV mono-infected because of similar rates of response 4,5 Background 1 Lo Re V, et al.

4. High SVR Rates in HCV/HIV-1 Co-Infected Patients Regardless of Baseline Characteristics | IAS 2015 | 21 July 2015 4 The 3-DAA (3D) regimen of ombitasvir (OBV), paritaprevir (co-dosed with ritonavir; PTV/r), and dasabuvir (DSV) with or without ribavirin (RBV) is approved in 49 countries to treat HCV genotype 1 (GT1) infection, including those with HIV-1 co-infection Background 6 Sulkowski MS, et al. JAMA. 2015;313(12):1223-31. In the TURQUOISE-I trial of HCV/HIV-1 co-infected patients with or without cirrhosis, rates of post-treatment week 12 sustained virologic response (SVR12) were 94% and 91% receiving 3D + RBV for 12 or 24 weeks, respectively 6
