Efficacy and Safety of CSA and Avatrombopag for the Treatment of SAA in the Elderly — SAA  

Severe Aplastic Anemia Clinical Trial

Official title:
A Multicenter, Single-arm Clinical Study of the Efficacy and Safety of CSA in Combination With Avatrombopag for the Treatment of Primary Treatment of Severe Aplastic Anemia in the Elderly

Clinical Trial Summary

This is a multicenter, single-arm clinical study. The objective was to evaluate the efficacy and safety of CSA in combination with Avatrombopag in elderly patients with very/sever aplastic anemia treated for the first time. The design was: cyclosporine 3 mg/kg orally in two divided doses, with cyclosporine trough concentrations maintained at 200-250 ng/ml for 3 months to achieve maximum efficacy, and Avatrombopag, which was administered in two dose groups, 40 mg orally once daily and 60 mg orally once daily, for a total of 24 weeks. Forty patients are expected to be enrolled in each dose group, and a total of 80 patients are expected to be enrolled if both dose groups are conducted. Evaluation endpoint: OR rate at 24 weeks of treatment.

Clinical Trial Description

This is a multicenter, single-arm clinical study to evaluate the efficacy and safety of CSA combined with Avatrombopag. The patients are older than 60 years with diagnosis of very sever/sever aplastic anemia(V/SAA) without treatment before. 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: two dosing groups, 40 mg orally once daily and 60 mg orally once daily, for a total of 24 weeks；Each dose group is expected to include 40 patients each. If the 40 mg dose group trial meets the desired trial objectives, the 60 mg dose group trial will not be conducted, and if the 40 mg dose group does not meet the desired trial objectives, the 60 mg dose group trial will be continued. A total of 80 patients were expected to be included if both dose groups were conducted.Overall response rate at 24 weeks of treatment and adverse events are the evaluation endpoint.Secondary study endpoints were: CRR and ORR at 12 and 52 weeks of treatment, CRR at 24 weeks, survival, and clonal evolution in follow-up. ;
