What is this trial about?

Immune thrombocytopenic purpura (ITP) is an autoimmune disorder characterized thrombocytopenia. Splenectomy is the standard treatment for patients who fails the first-line treatment: corticosteroid. Rituximab, has recently emerged as a promising treatment for ITP. The aim of the study is to determine whether early treatment with Rituximab can result in durable remissions, and consequently, lead to the avoidance of splenectomy in a significant number of patients.
