Detailed description

This is a multicenter, single-arm clinical study to evaluate the efficacy and safety of Avatrombopag combined with IST as the first-line regimen for aplastic anemia. The patients are diagnosed as hepatitis associated with very sever/sever aplastic anemia(V/SAA) or V/SAA with abnormal liver function before treatment. Patients received p-ATG for 5 consecutive days (day 1-5), at a dose of 20 mg/kg/day. CSA is started at 3 mg/kg orally in two doses. Concentrations maintained at 200-250 ng/ml to achieve maximum efficacy and then tapered by 25 mg every 3 months; Avatrombopag: 40 mg orally once daily for a total of 12 weeks. A total of 39 patients were expected to be included.Complete response rate at 12 weeks of treatment and adverse events are the evaluation endpoint.Secondary study endpoints were: ORR at 12 , CRR and ORR at 24 weeks, survival, and clonal evolution in follow-up.
