GSK granted FDA approval for Promacta

PHILADELPHIA — The Food and Drug Administration has approved a GlaxoSmithKline drug for a rare blood disorder, GSK said Friday.

The drug maker announced the approval of Promacta (eltrombopag) for chronic immune thrombocytopenic purpura, or ITP, in patients who have not responded adequately to other therapies. Chronic ITP results in increased destruction of inadequate production of platelets in the blood, creating an increased risk of bruising and bleeding.

The FDA granted Promacta orphan drug designation in May 2008 and accelerated approval in November 2008.
