On November 20, 2008, eltrombopag (Promacta) received approval from the US Food and Drug Administration (FDA) for the treatment of thrombocytopenia in patients with chronic immune thrombocytopenic purpura (ITP) who have had an insufficient response to corticosteroids, immunoglobulins, or splenectomy. This report summarizes the FDA analyses of the clinical data supporting this approval. ⋯ The US FDA approved eltrombopag for use among certain patients with chronic ITP based upon demonstration of a favorable risk-to-benefit profile, where the major benefit pertained to demonstration of a clinically important increase in blood platelets among a population of patients relatively refractory to prior therapies.
