Clinical Trial: SB497115 (Oral Thrombopoietin Receptor Agonist) Versus Placebo in Adults with Refractory Immune Thrombocytopenic Purpura
This study is currently recruiting patients.
|
Purpose
SB497115 is an oral agent which activates the thrombopoietin receptor and increases platelet counts in healthy volunteers. This study is examining several different doses of SB497115 as a treatment for patients with ITP (immune thrombocytopenic purpura) who have failed prior therapy. Following identification of the optimal dose, the study will randomize 150 additional patients to either SB497115 or placebo (for every 2 patients who receive SB497115, 1 patient will receive placebo). The study is designed to determine the proportion of patients with a platelet count greater than or equal to 50,000 platelets/microliter after 42 days.
