Brief Summary

Aplastic anemia (AA) is a group of clinical syndromes caused by a significant decrease in bone marrow hematopoietic tissue from different etiologies, resulting in hematopoietic failure. Treatment options for patients with aplastic anemia are very limited. In a phase II/III, multicenter, open-label study exploring the efficacy and safety of romiplostim, the primary endpoint showed an overall response rate of 84% \[95% CI 66-95%\] at week 27. However, there are no prospective clinical data exploring whether romiplostim combined with ciclosporin (CsA) can further improve efficacy than ciclosporin monotherapy in newly diagnosed NSAA. Therefore, we aimed to compare the efficacy and safety of romiplostim in combination with CsA versus CsA monotherapy.

Study Arms (2)

Romiplostim+CsA

EXPERIMENTAL

Romiplostim 10 µg/kg, subcutaneous injection, once a week, for at least 3 months. Patients with platelet count ≥50×109/L can stop using, and continue to use with platelet count \< 50×109/L. Ciclosporin 3-5mg/kg/d, adjust the dose to keep trough ciclosporin plasma concentration 100-200ng/ml. Ciclosporin should be used for at least 6 months to evaluate the efficacy. Effective patients will continue to use ciclosporin for at least 1.5 years, followed by a slow reduction.

Drug: RomiplostimDrug: Ciclosporin

CsA

EXPERIMENTAL

Ciclosporin 3-5mg/kg/d, adjust the dose to keep trough ciclosporin plasma concentration 100-200ng/ml. Ciclosporin should be used for at least 6 months to evaluate the efficacy. Effective patients will continue to use ciclosporin for at least 1.5 years, followed by a slow reduction.

Drug: Ciclosporin

Interventions
