PHOTON-1 Study: SOF + RBV in HCV-HIV co-infection Summary In this open-label, non-randomised, uncontrolled study, patients with HCV who were co-infected with HIV had high rates of SVR 12 with the oral, IFN-free, combination of SOF + RBV –After 24 weeks of therapy for genotype 1 treatment-naïve and genotype 2 and 3 treatment-experienced –After 12 weeks of therapy for genotype 2 treatment-naïve Low rate of discontinuation for adverse events, however somewhat higher than in HCV monoinfected patients Confirmation of the high barrier to resistance of SOF (no resistance mutations at failure) Limitations –Underrepresentation of women and patients with cirrhosis –Absence of a control group Sulkowski M.
