NCT05433922

Brief 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.

Study Arms (1)

CSA + Avatrombopag

EXPERIMENTAL

cyclosporine 3 mg/kg orally in two doses, with cyclosporine trough concentrations maintained at 200-250 ng/ml for 3 months 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.If the 40 mg dose group trial meets the desired trial objectives, the 60 mg dose group trial will not be conducted.

Drug: Avatrombopag

Interventions

cyclosporine in combination with Avatrombopag to treat

Also known as: CSA
CSA + Avatrombopag

Eligibility Criteria

Age60 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • elderly patients with V/SAA with a definite diagnosis.
  • age greater than 60 years, male or female.
  • Subjects must complete all screening assessments as outlined in the trial protocol.
  • Able to swallow or administer the drug orally.
  • Cannot tolerate or refuse ATG therapy.
  • No prior treatment with cyclosporine, tacrolimus or hormones or treatment for no more than 2 weeks.
  • 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.
  • 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.

You may not qualify if:

  • No subject shall be enrolled in this study if he/she meets any of the following 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.);
  • Patients with uncontrolled bleeding and/or infection despite standard treatment.
  • patients with previous history of hematopoietic stem cell transplantation;
  • previous history of thrombosis.
  • Patients with concurrent malignancy or potential cancer on immunosuppressive therapy.
  • Those who are considered unsuitable for enrollment by the investigator.
