Woburn, MA, Feb. 26, 2026 (GLOBE NEWSWIRE) -- 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
FERABRIGHT™ (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.
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
Adverse Reactions
These are not all the possible side effects of FERABRIGHT. Please see Adverse Reactions (6) in the Prescribing Information for a full list.
The Important Safety Information does not include all the information needed to use FERABRIGHT safely and effectively. For more information and full prescribing information, please visit www.Ferabright.com.
