简要总结
This is a prospective, multicenter, single-arm, phase 2 trial. The aim of this study is to evaluate the efficacy and safety of herombopag combined with cyclosporine for patients with non severe aplastic anemia (NSAA).
详细描述
This study aims to improve the 24 weeks response rate. The sample size is calculated based on Simon's two-stage design. The first stage of the study enrolled a cohort of 15 patients. If after 24 weeks at least 9 patients achieved a response, then enrollment was expanded to a total of 43 patients. The null hypothesis was unaccepted if more than 26 of 43 patients achieved the response. Accounting for a 20% dropout rate, the estimated final sample size was 54 patients.
