Sofosbuvir plus daclatasvir with or without ribavirin has demonstrated a high efficacy and an acceptable safety profile in clinical trials of patients infected with genotype 2 hepatitis Cvirus (HCV); however, there are currently no real‐world data available for this regimen. To evaluate the real‐life safety and efficacy of sofosbuvir/daclatasvir with or without ribavirin in genotype 2 HCV patients in the French cohort ANRS CO22 HEPATHER(NCT01953458). In this ongoing, national, multicentre, prospective, observational study, we observed patients with HCV genotype 2 infection who initiated treatment with sofosbuvir (400 mg/d) plus daclatasvir with or without ribavirin (1‐1.2 g/d). Patients were divided into two treatment groups: sofosbuvir/daclatasvir with or without ribavirin (12 weeks/24 weeks). The primary end point was a sustained virological response at week 12 following the end of therapy. Overall, 88% and 91% of patients achieved a sustained virological response following 12 and 24 weeks of treatment with sofosbuvir/daclatasvir with or without ribavirin, respectively. The most common adverse events were asthenia (29%), headache (15%) and fatigue (20%), and ribavirin addition was associated with a higher rate of adverse events and treatment discontinuation. Sofosbuvir/daclatasvir with or without ribavirin was associated with lower rates of sustained virological response in the real‐life setting compared with the clinical setting and demonstrated suboptimal efficacy for the treatment of patients with genotype 2 chronic HCV.
