Official Title: A Dose-Finding Study Evaluating the Safety and Efficacy of AMG 531 in Thrombocytopenic Subjects With Immune Thrombocytopenic Purpura (ITP)
Brief Summary: The purposes of this study are: to determine a weekly dose that demonstrates a satisfactory safety profile and sustains elevated platelet counts within a targeted therapeutic level (a doubling of baseline platelet counts and within the range of greater than or equal to 50 x 10^9/L and less than or equal to 450 x 10^9/L in thrombocytopenic subjects with ITP; to assess Amgen megakaryopoiesis protein 2 [AMP2 (AMG 531)] pharmacokinetics (PK) in thrombocytopenic subjects with ITP.
