Ferumoxytol

Ferabright is the first and only iron-based contrast agent for MRI in the brain Woburn, MA — February 26, 2026 — Azurity Pharmaceuticals, Inc. announced today that FerabrightTM (ferumoxytol injection) is now available in the U.S. Ferabright is the first and only iron-based contrast agent indicated for magnetic resonance imaging (MRI) of the brain in adults with known or suspected malignant neoplasms in the brain to visualize lesions with a disrupted blood-brain barrier.1 Ferabright was approved by the U.S. Food and Drug Administration (FDA) in October 2025. “Ferabright is an advanced superparamagnetic iron oxide nanoparticle contrast agent engineered for high relaxivity,” said Ronald Scarboro, CEO of Azurity Pharmaceuticals. “It significantly enhances image contrast and precision in brain tumor delineation compared to non-contrast MRI, offering clinicians a new tool for diagnostic imaging and improved patient care.” In a clinical trial, Ferabright-enhanced MRI significantly improved visualization of primary and secondary brain neoplasms compared with pre-contrast imaging.1 In addition to improved imaging, Ferabright offers an extended imaging window due to its long half-life.1 The relatively large molecular size of Ferabright means it remains intravascular during early time points (blood pool phase) with a plasma elimination half-life of ~21 hours.1,7,9 Brain tumor enhancement is best seen in delayed-phase MRI, when contrast enhancement marks blood-brain barrier breakdown and macrophage uptake.1,2,7,9,10 As an iron-based agent, Ferabright is processed through the body’s natural iron metabolism pathways,3,6,7 potentially reducing concerns related to long-term tissue retention associated with other contrast agents.2,8 And unlike many other agents, Ferabright is a contrast alternative for patients with renal insufficiency and other gadolinium contraindications,2,3,4 enabling access to contrast-enhanced MRI while reducing exposure to heavy metals found in other contrast agents.5 Using an iron‑based contrast agent may also support more environmentally sustainable imaging practices by reducing contrast‑related emissions.11,12,13,14 Azurity Pharmaceuticals acknowledges the invaluable contributions of the Oregon Health & Science University (OHSU) team and the patients who participated in the foundational research, with special recognition to the late Edward Neuwelt, MD, professor and lead investigator in OHSU’s Department of Neurology, whose pioneering work played a critical role in advancing Ferabright toward FDA authorization. “Ferumoxytol expands our MRI toolkit and provides an option for patients who are either contraindicated for or decline gadolinium,” said Csanad Varallyay, MD, PhD, Neuroradiologist based in Portland, Oregon, with longstanding research experience in ferumoxytol-enhanced MRI. Ferabright will be supplied in single-dose vials of 300 mg elemental iron per 10 mL (30 mg/mL) and 510 mg elemental iron per 17 mL (30 mg/mL) for intravenous infusion over at least 15 minutes.1 Ferabright is contraindicated in patients with known hypersensitivity to ferumoxytol, any of Ferabright’s components, or any other intravenous iron products. Reactions have included anaphylaxis.1 IMPORTANT SAFETY INFORMATION FERABRIGHTTM (ferumoxytol injection), for intravenous use FERABRIGHT is indicated for magnetic resonance imaging (MRI) of the brain in adults with known or suspected malignant neoplasms in the brain to visualize lesions with a disrupted blood-brain barrier. WARNING: ANAPHYLAXIS AND OTHER SERIOUS HYPERSENSITIVITY REACTIONS Fatal and serious hypersensitivity reactions, including anaphylaxis, have occurred in patients receiving ferumoxytol products that contain the same active ingredient as FERABRIGHT. Initial signs may include hypotension, syncope, unresponsiveness, and cardiac/cardiorespiratory arrest. Hypersensitivity reactions have occurred even in patients who previously tolerated ferumoxytol. Only administer FERABRIGHT as an intravenous infusion over at least 15 minutes and only when personnel and therapies are immediately available for the treatment of anaphylaxis and other hypersensitivity reactions. Observe for signs or symptoms of hypersensitivity reactions during and for at least 30 minutes following FERABRIGHT infusion including monitoring of blood pressure and pulse during and after FERABRIGHT administration [see Warnings and Precautions (5.1)]. ADDITIONAL IMPORTANT SAFETY INFORMATION Contraindications FERABRIGHT is contraindicated in patients with known hypersensitivity to ferumoxytol, any of FERABRIGHT’s components, or any other intravenous iron products. Reactions have included anaphylaxis [see Warnings and Precautions (5.1)]. Warnings and Precautions Anaphylaxis and Other Serious Hypersensitivity Reactions: Fatal and serious hypersensitivity reactions, including anaphylaxis presenting with cardiac/cardiorespiratory arrest, clinically significant hypotension, syncope, or unresponsiveness, have occurred in patients receiving ferumoxytol products, which contain the same active ingredient as FERABRIGHT. Other adverse reactions potentially associated with hypersensitivity have occurred, including pruritus, rash, urticaria, and wheezing. These reactions have occurred in patients who had no prior exposure to ferumoxytol as well as in patients who previously tolerated ferumoxytol. Patients with a history of multiple drug allergies may have a greater risk of anaphylaxis with FERABRIGHT. Elderly patients with multiple or serious co-morbidities who experience hypersensitivity reactions and/or hypotension following administration of ferumoxytol including FERABRIGHT may have more severe outcomes. Carefully consider the potential risks and benefits before administering FERABRIGHT to these patients. FERABRIGHT is contraindicated in patients with known hypersensitivity to ferumoxytol, any of FERABRIGHT’s components, or any other intravenous iron products [see Contraindications (4)]. Only administer FERABRIGHT as an intravenous infusion over at least 15 minutes and only when personnel and therapies are immediately available for the treatment of anaphylaxis and other hypersensitivity reactions. Closely observe patients for signs and symptoms of hypersensitivity including monitoring of blood pressure and pulse during and after FERABRIGHT administration for at least 30 minutes and until clinically stable following completion of infusion. Allow at least 30 minutes after FERABRIGHT infusion for administration of any other medications that may cause serious hypersensitivity reactions or hypotension [see Dosage and Administration (2.1)]. In a clinical study in patients with iron deficiency anemia (IDA) (FERABRIGHT is not approved to treat IDA), regardless of etiology, hypersensitivity reactions were reported in 0.4% (4/997) of patients administered ferumoxytol as an intravenous infusion over at least 15 minutes. These included one patient with severe hypersensitivity reaction and three patients with moderate hypersensitivity reactions. In clinical studies predominantly in patients with IDA and chronic kidney disease (CKD) (FERABRIGHT is not approved to treat IDA or CKD), serious hypersensitivity reactions were reported in 0.2% (4/1,806) of patients administered ferumoxytol as a rapid intravenous injection (not an approved method of administration for FERABRIGHT). Other adverse reactions potentially associated with hypersensitivity (e.g., pruritus, rash, urticaria, or wheezing) were reported in 3.5% (63/1,806) of these patients. In postmarketing experience with ferumoxytol, fatal and serious anaphylactic type reactions presenting with cardiac/cardiorespiratory arrest, clinically significant hypotension, syncope, and unresponsiveness have been reported [see Adverse Reactions (6.2)]. Hypotension: FERABRIGHT may cause clinically significant hypotension. Monitor patients for signs and symptoms of hypotension following FERABRIGHT administration [see Dosage and Administration (2.1) and Warnings and Precautions (5.1)]. In a clinical study in patients with IDA (FERABRIGHT is not approved to treat IDA), moderate hypotension was reported in 0.2% (2/997) of patients administered ferumoxytol as an intravenous infusion over 15 minutes. In clinical studies in patients with IDA and CKD (FERABRIGHT is not approved to treat IDA or CKD), hypotension was reported in 1.9% (35/1,806) of patients, including three patients with serious hypotensive reactions, who were administered ferumoxytol as a rapid intravenous injection (not an approved method of administration for FERABRIGHT). Hypotension has also been reported in postmarketing experience [see Adverse Reactions (6.2)]. Iron Overload: Use of FERABRIGHT can lead to excess storage of iron with the possibility of iatrogenic hemosiderosis. Avoid use of FERABRIGHT in patients with iron overload. Magnetic Resonance Imaging Test Interference: Administration of FERABRIGHT may transiently affect the diagnostic ability of MRI. Conduct anticipated MRI studies (other than the intended FERABRIGHT brain imaging) prior to the administration of FERABRIGHT. Alteration of MRI studies may persist for up to 3 months following the FERABRIGHT dose. If MRI is required within 3 months after FERABRIGHT administration, use T1- or proton density-weighted pulse sequences to minimize the FERABRIGHT effects. MRI imaging using T2-weighted pulse sequences should not be performed earlier than 4 weeks after the administration of FERABRIGHT. Maximum alteration of vascular MRI signal is evident for 1 to 2 days following FERABRIGHT administration [see Clinical Pharmacology (12.3)]. FERABRIGHT will not interfere with X-ray, computed tomography (CT), positron emission tomography (PET), single photon emission computed tomography (SPECT), planar nuclear medicine imaging, or ultrasound. Differences in Magnetic Resonance Imaging Appearance Compared to Gadolinium-Based Contrast: MRI obtained with FERABRIGHT may demonstrate different size, intensity, and pattern of contrast signal in lesions compared to images obtained with gadolinium-based contrast [see Clinical Studies (14)]. Be aware of the potentially limited interpretability of changes in lesion contrast appearance if prior images were not obtained with FERABRIGHT. Adverse Reactions The most common adverse reactions (≥0.65%) are nausea, pruritus, constipation, headache, diarrhea, increased blood pressure, bleeding, hyperpigmentation, vein injury, taste alteration, burning/tingling sensation with injection, red sclera, allergic rhinitis, back pain, vomiting, and increased ALT. (6.1) Additional adverse reactions (≥1%) reported in clinical trials of patients with IDA or patients with IDA and CKD (using dosing regimens and indications not approved for FERABRIGHT), included dizziness, fatigue, peripheral edema, edema, abdominal pain, cough, pyrexia, dyspnea, and muscle spasm.
