Brief summary

This is a multicenter, single-arm clinical study. The objective was to evaluate the efficacy and safety of Avatrombopag combined with IST in very/sever aplastic anemia patients with abnormal liver function or HAAA patients treated for the first time. The design was: Patients received p-ATG for 5 consecutive days (day 1-5), at a dose of 20 mg/kg/day. 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 the dose of 40 mg orally once daily for a total of 12 weeks. Thirty-nine patients are expected to be enrolled in this study. Evaluation endpoint: complete response rate at 12 weeks of treatment.

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.

Able to swallow or administer the drug orally. 5. No prior application of TPO receptor agonists (including Thrombopoietin, Eltrombopag, Hetrombopag, etc.) or application of TPO receptor agonists for treatment with ≤ 5 total doses and ≤ 7 days of TPO receptor agonist drugs such as Eltrombopag, Hetrombopag, etc. 6. Diagnosis as HAAA or abnormal liver function. ALT and AST more than 1.5 times of upper limit. 7. Informed consent must be signed prior to the start of all specific study procedures, in consideration of the patient's condition, or by a member of the patient's immediate family if the patient's signature is not conducive to the treatment of the condition.

Exclusion criteria

Known diagnosis of congenital hematopoietic failure disorders (e.g. Fanconi anemia) and other causes of allogeneic cytopenias and bone marrow hypoproliferative disorders (e.g. hemolytic PNH, hypoproliferative MDS/AML, autoantibody-mediated allogeneic cytopenias, etc.); 2. Patients with uncontrolled bleeding and/or infection despite standard treatment. 3. Patients with previous history of hematopoietic stem cell transplantation; previous history of thrombosis. 4. Patients with concurrent malignancy or potential cancer on immunosuppressive therapy. 5. Those who are considered unsuitable for enrollment by the investigator.
