Romiplostim
Romiplostim (Nplate™) is a protein called a peptibody. The active peptide component stimulates the thrombopoietin (“TPO”) receptor resulting in increased platelet production. It is being investigated for the treatment of chronic immune (idiopathic) thrombocytopenic purpura (“ITP”). ITP is an autoimmune bleeding disorder characterized by an abnormal decrease in platelets, a condition known as thrombocytopenia.

Data from two phase 3 clinical studies evaluating romiplostim for the treatment of thrombocytopenia in ITP (studying pre- and post-splenectomy ITP) met both primary and secondary endpoints. Based on positive results from these studies, we submitted a BLA with the FDA for the treatment of thrombocytopenia in adult patients with chronic ITP in October 2007 and also completed regulatory filings for this indication in Europe, Canada, and Australia. The FDA has granted priority review for Nplate™ which will be discussed at the March 2008 ODAC meeting.  We expect a regulatory decision in the first half of 2008.

We are also evaluating AMG 531 in myelodysplastic syndromes (“MDS”) and chemotherapy-induced thrombocytopenia (“CIT”). Phase 2 studies in each setting were initiated in 2006. The trials are currently ongoing and we continue to evaluate the safety and efficacy of AMG 531 in these settings.
