Treatment with the Thrombopoietin (TPO)-Receptor Agonist Romiplostim in Thrombocytopenic Patients (Pts) with Low or Intermediate-1 (Int-1) Risk Myelodysplastic Syndrome (MDS): Results of a Randomized, Double-Blind, Placebo(PBO)-Controlled Study

Abstract

Abstract Abstract 117 Background: There are few therapies for thrombocytopenia in MDS, which is found in ∼50% of pts with low/int-1 MDS and is associated with shortened survival. Methods: IPSS low/int-1 MDS pts receiving supportive care, with platelets 1) ≤20×109/L or 2) ≤ 50×109/L with a history of bleeding, were randomized 2:1 to 750 μg romiplostim:PBO for 26 wk with MDS supportive care, and a 4-wk washout followed by bone marrow (BM) biopsy. Pts continued as randomized, with any MDS therapy, for 24 wk with another 4-wk washout followed by a BM biopsy. The ..
