Background. Daclatasvir and asunaprevir dual therapy is approved for the treatment of HCV genotype 1b infection in several countries. AIM: To evaluate the efficacy and safety of daclatasvir and asunaprevir dual therapy in Turkish patients. MATERIAL AND METHODS: Sixty-one patients with HCV genotype 1b were enrolled in the Turkish early access program. Most of the patients were in difficult-to-treat category. Patients were visited at each 4 week throughout the follow-up period. Laboratory findings and adverse events were recorded at each visit. RESULTS: Fifty-seven of 61 enrolled patients completed 24 weeks of treatment. Two patients died as a result of underlying diseases at 12-14th weeks of treatment. Two patients stopped the treatment early as a consequence of virological breakthrough, and 2 patients had viral relapse at the post-treatment follow-up. Overall SVR12 rates were 90% (55/61) and 93.2% (55/59) according to intention-to-treat (ITT) and per protocol (PP) analysis respectively. In ITT analysis, SVR12 was achieved by 93% (13/14) in relapsers, 80% (12/15) in interferon-ineligible patients and 91% (20/22) in previous nonresponder patients. SVR12 rates were 86.5% and 91.4% in patients with cirrhosis according to ITT and PP analysis respectively. SVR12 was 95.8% in non-cirrhosis group in both analysis. Patients with previous protease inhibitor experience had an SVR12 of 87.5%. Common adverse events developed in 28.8% of patients. There were no treatment related severe adverse event or grade-4 laboratory abnormality. CONCLUSIONS: Daclatasvir and asunaprevir dual therapy is found to be effective and safe in difficult-to-treat Turkish patients with HCV genotype 1b infection.
