Primary Outcome Measures

Name	Time	Method
Main Objective: The primary objective is to provide long-term safety data for the use of romiplostim in thrombocytopenic subjects with myelodysplastic syndromes (MDS).;Secondary Objective: The secondary objective is to evaluate the effectiveness of romiplostim with respect to platelet response, transfusion, and bleeding events in the treatment of thrombocytopenic subjects with MDS.;Primary end point(s): The primary endpoint is the incidence of all adverse events, including clinically significant changes in laboratory values and incidence of antibody formation.
