Romiplostim in Patients undergoing Hematopoietic Stem Cell Transplantation: Results of a Phase I/II multicenter Trial

Persisting severe thrombocytopenia more than 6 weeks after allogeneic stem cell transplantation is a common problem associated with adverse prognosis. Peffault de Latour et al report the results of the first trial of the thrombopoietin mimetic, romiplostim, in this setting, demonstrating recovery of platelet counts in 18 of 24 patients.
