These clinical trials also included patient-reported outcomes data as pre-specified secondary and exploratory endpoints. These outcomes endpoints, including quantitative measures of patients’ fatigue and measures of quality of life, captured the negative impact anemia has on these patients’ lives pre-treatment – and the significant improvement in these scores following a one gram course of therapy with ferumoxytol. These data, and the safety and efficacy data from both IDA-301 and IDA-302 were presented at the 2012 Annual Meeting of the American Society of Hematology.About Iron Deficiency Anemia More than 4 million Americans have IDA; 1.6 million of whom are estimated to have CKD, while the other 2.4 million suffer from anemia due to other causes. 1 For these patients with anemia due to other causes, the underlying diseases or issues causing IDA include abnormal uterine bleeding, gastrointestinal disorders, inflammatory diseases and chemotherapy-induced anemia. Many IDA patients fail treatment with oral iron due to intolerability or side effects. 2 About AMAG AMAG Pharmaceuticals, Inc. is a specialty pharmaceutical company that manufactures and markets Feraheme® in the United States.
