FERAHEME delivers clinical efficacy in just 1 gram1,2

In the largest IV iron head-to-head, double-blind, non-inferiority trial of ~2000 patients, 1 gram of FERAHEME vs 1.5 grams of Injectafer® demonstrated the following2

FERAHEME does not require pretreatment
or a test dose prior to use

Moderate HSR was defined as requiring minimal medical intervention or corrective treatment; severe HSR was characterized as requiring medical intervention or corrective treatment, with possible hospitalization. Anaphylaxis was defined as a sudden, severe, potentially fatal systemic allergic reaction as operationally defined using the Sampson criteria. Hypotension was defined as a >30% decrease from baseline in systolic blood pressure or a decrease of >20 mm Hg in systolic blood pressure with symptoms (dizziness/lightheadedness, fatigue, syncope, lack of consciousness, blurred vision).2

CI=confidence interval; Hgb=hemoglobin; HSR=hypersensitivity reaction; IDA=iron deficiency anemia.

Select Important Safety Information: Excessive therapy with parenteral iron can lead to excess storage of iron with the possibility of iatrogenic hemosiderosis. Regularly monitor the hematologic response during parenteral iron therapy. Do not administer FERAHEME to patients with iron overload.

SD=standard deviation; TSAT=transferrin saturation.
