Objective: To evaluate the real-world safety and curative effect of ombitasvir combined with dasabuvir for the treatment of chronic hepatitis C 1b genotype infection in non-cirrhotic or compensated cirrhotic patients. Methods: A real-world research method was adopted, and the research was conducted at three medical centers of mainland China. Non- cirrhotic or compensated cirrhotic patients with HCV genotype 1b infection who were initially treated with IFN/PEG-IFN-alpha combined with ribavirin, and ombitasvir combined with dasabuvir for 8 or 12 weeks were taken. Sustained virological response (SVR) and the incidence of adverse events during treatment and follow-up were evaluated after 12 weeks of drug withdrawal at OBV/PTV/r 25/150/100mg once daily and DSV 250mg, twice daily. Median and range were used for description of non-normally distributed data. Results: 80 cases of GT1b were included in this study. Of these 88.8% (71/80) were newly diagnosed, 12.5% (10/80) were compensated cirrhotic, 97.5% (78/80) received 12 weeks treatment, and 2.5% (2/80) received 8 weeks treatment. The rate of HCV RNA negative at EOT (end of treatment) was 100% (64/64). A total of 67 patients completed the treatment within 12 weeks, and 43 patients returned to the hospital for further consultations, and SVR12 was 100%(43/43). No patient discontinued the drugs because of an adverse event during treatment. Conclusion: In the real world, Ombitasvir combined with dasabuvir for the treatment of chronic hepatitis C 1b genotype infection in China has 100% rates of EOT and SVR12 with well- tolerability and safety.
