LEXINGTON, Mass.--(BUSINESS WIRE)--AMAG Pharmaceuticals, Inc., a biopharmaceutical company focused on the development and commercialization of a therapeutic iron compound to treat anemia and novel imaging agents to aid in the diagnosis of cancer and cardiovascular disease, today provided a safety update on Feraheme® (ferumoxytol) Injection for intravenous use.

Since the commercial launch of Feraheme in July 2009, serious adverse events have been reported at a rate consistent with that contained in the U.S. package insert. Of the estimated 35,000 patient exposures to date, 40 serious adverse events have been reported, an approximate rate of 0.1 percent. No mortality signal has been observed. A single reported death occurred in a patient two days post-Feraheme treatment, which the Company does not believe was the result of Feraheme.

Important Safety Information about Feraheme

Feraheme is indicated for the treatment of iron deficiency anemia in adult patients with chronic kidney disease. Feraheme is contraindicated in patients with evidence of iron overload, known hypersensitivity to Feraheme or any of its components, and patients with anemia not caused by iron deficiency.

In clinical studies, hypotension was reported in 1.9% (33/1,726) of subjects receiving Feraheme, including three patients with serious hypotensive reactions. Serious hypersensitivity reactions were reported in 0.2% (3/1726) of patients. Patients should be observed for signs and symptoms of hypersensitivity for at least 30 minutes following Feraheme injection and the drug should only be administered when treatment for hypersensitivity reactions is readily available. Excessive therapy with parenteral iron can lead to excess storage of iron with the possibility of iatrogenic hemosiderosis. Patients should be regularly monitored for hematologic response during parenteral iron therapy. As a superparamagnetic iron oxide, Feraheme may transiently affect magnetic resonance diagnostic imaging but will not affect X-ray, CT, PET, SPECT, ultrasound, or nuclear imaging.

In clinical trials, the most commonly occurring adverse reactions in Feraheme treated patients versus oral iron treated patients were diarrhea, nausea, dizziness, hypotension, constipation and peripheral edema.
