COPENHAGEN, Denmark--(BUSINESS WIRE)--Amgen Inc. (NASDAQ: AMGN) today announced updated results from the ongoing, open-label extension study on the long-term safety and efficacy of romiplostim in adult patients with chronic immune thrombocytopenic purpura (ITP), a chronic and serious autoimmune disorder characterized by low platelet counts in the blood. The updated results continue to show that romiplostim increased and sustained platelet counts with extended treatment, and reduced the need for concurrent and rescue ITP medications.
