AMAG Completes Feraheme® (ferumoxytol) FDA Submission for the Treatment of All Adult Patients With Iron Deficiency Anemia


Posted on: 03 Aug 17

Filing includes results of head-to-head Phase 3 clinical trial evaluating Feraheme compared to ferric carboxymaltose injection

Potential approval and launch in the first half of 2018

WALTHAM, Mass., Aug. 03, 2017 (GLOBE NEWSWIRE) -- Pharmaceuticals, Inc. (NASDAQ:AMAG) today announced that it has completed the submission to the U.S. Food and Drug Administration (FDA) to broaden the existing label for Feraheme® (ferumoxytol) to include the treatment of all adults with iron deficiency anemia (IDA) who have an intolerance or unsatisfactory response to oral iron. AMAG anticipates an FDA decision on the filing in the first half of 2018. The current indication of Feraheme is limited to the treatment of IDA in adults with chronic kidney disease (CKD) who have failed or cannot tolerate oral iron treatment.

“Approximately 4.5 million Americans have been diagnosed with IDA and suffer from its debilitating effects.1 This filing brings us closer to the possibility of offering an alternative intravenous treatment option to those patients who have failed or are intolerant to oral iron, including approximately 1.5 million women with IDA who suffer from gynecological issues, including abnormal uterine bleeding," said Julie Krop, M.D., chief medical officer and senior vice president of clinical development and regulatory affairs at AMAG. “We are very pleased with the recent Phase 3 clinical trial results that are included in the submission, and would like to thank the many patients and study site participants who contributed to this important achievement.”  

The submission is, in part, supported by positive results from a previously announced Phase 3 randomized, double-blind, non-inferiority clinical trial that evaluated Feraheme compared to Injectafer® (ferric carboxymaltose injection) in approximately 2,000 adults with IDA who had failed or could not tolerate oral iron or in whom oral iron was contraindicated. The study met its pre-specified primary endpoint of demonstrating non-inferiority to Injectafer® based on the primary composite endpoint of the incidence of moderate-to-severe hypersensitivity reactions (including anaphylaxis) or moderate-to-severe hypotension. Additionally, the trial met secondary safety and efficacy endpoints, including the demonstration of superiority to Injectafer in efficacy as measured by mean improvement in hemoglobin per gram of iron administered from baseline to week 5. Importantly, there were no meaningful differences in the safety profile between the two agents, with the exception that study results showed a markedly greater incidence of hypophosphatemia (defined by blood phosphorous of <0.6 mmol/L from baseline to week 2) in the patients dosed with Injectafer compared to those in the Feraheme arm of the trial (Feraheme: 0.4% of patients; Injectafer: 38.7% of patients: rate difference: -38.3%; 95% confidence interval: -41.46% to -35.15%).

About Feraheme® (ferumoxytol)
Feraheme received marketing approval from the FDA in June 2009 for the treatment of IDA in adult CKD patients and was commercially launched by AMAG in the U.S. shortly thereafter. Ferumoxytol is protected in the U.S. by seven issued patents covering the composition and dosage form of the product. Six of the issued patents are listed in the FDA’s Orange Book, the last of which expires in June 2023.

Fatal and serious hypersensitivity reactions including anaphylaxis have occurred in patients receiving Feraheme. Initial symptoms may include hypotension, syncope, unresponsiveness, cardiac/cardiorespiratory arrest. Feraheme is contraindicated in patients with a known hypersensitivity to Feraheme or any of its components, or a history of allergic reaction to any intravenous iron product.
