Romiplostim in Combination With CsA vs. CsA in the Treatment of Newly Diagnosed NSAA

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.
