Dihydroergotamine Mesylate

Atzumi™ (dihydroergotamine(DHE)) nasal powder is the first and only DHE nasal powder for the acute treatment of migraine with or without aura in adults in an easy-to-use, easy-to-carry device. Atzumi is the first and only product utilizing the SMART (Simple MucoAdhesive Release Technology) platform which combines a proprietary advanced powder and device technology to simplify delivery of DHE. In clinical studies, Atzumi administration provided rapid and sustained DHE concentrations with low variability. DURHAM, N.C., April 30, 2025 /PRNewswire/ -- Satsuma Pharmaceuticals, Inc., a late-stage biopharmaceutical company dedicated to bringing novel treatments to people who suffer from migraine and other debilitating conditions, and its corporate parent, Shin Nippon Biomedical Laboratories, Ltd. (TSE:2395), today announced that the U.S. Food and Drug Administration (FDA) has approved a 505(b)(2) New Drug Application (NDA) for Atzumi™(dihydroergotamine (DHE)) nasal powder for the acute treatment of migraine with or without aura in adults. Atzumi was previously known as STS101. Migraine is a neurological disorder that is thought to be the result of temporary changes in the chemicals, nerves and blood vessels in the brain, with symptoms that are often incapacitating. According to the American Migraine Foundation, approximately 40 million Americans live with migraine. It is the second leading cause of disability worldwide in terms of time lost to disability and most common cause of disability among young women. "The approval of Atzumi is a milestone to celebrate, providing a new option for the acute treatment of migraine combining long-proven benefits of DHE with a patient-friendly and easy-to-use delivery system developed based on SNBL's novel intranasal drug delivery platform technology," said Dr. Ryoichi Nagata, President and CEO of Satsuma. "We believe that Atzumi will contribute to improving the quality of life of patients struggling for relief from these highly disabling problems." "DHE plays a unique clinical role in the acute treatment of migraine, providing patients long lasting effects and the unique ability to provide benefit even when taken late in a migraine attack. The convenience of Atzumi, the only DHE nasal powder, will offer patients ease of use combined with the important known DHE clinical advantages", said Dr. Stewart J. Tepper, M.D., Vice President of the New England Institute for Neurology and Headache in Stamford, Connecticut. About Atzumi Atzumi is a proprietary drug device product incorporating both Satsuma's advanced nasal powder formulation of dihydroergotamine (DHE) administered via its unique nasal delivery device. The product is designed to provide patients an easy-to-use and easy-to-carry treatment option. The FDA approval for Atzumi is based on two clinical studies (Phase 1 PK trial and ASCEND Phase 3 open-label, long-term safety trial), which demonstrated fast absorption, rapid achievement of high DHE plasma concentrations, and sustained DHE plasma levels over time as well as safety and tolerability in subjects with migraine. About Dihydroergotamine (DHE) Since its approval in 1946, DHE has long been recommended in published migraine treatment guidelines as a first-line acute treatment option for migraine and has significant advantages versus other anti-migraine treatments for many patients. However, disadvantages of current DHE liquid nasal spray and injectable products, including invasive and burdensome administration and/or sub-optimal clinical performance, have limited the widespread use of DHE. IMPORTANT SAFETY INFORMATION WARNING: PERIPHERAL ISCHEMIA FOLLOWING COADMINISTRATION WITH STRONG CYP3A4 INHIBITORS Serious and/or life-threatening peripheral ischemia has been associated with the coadministration of dihydroergotamine with strong CYP3A4 inhibitors. Because CYP3A4 inhibition elevates the serum levels of dihydroergotamine, the risk for vasospasm leading to cerebral ischemia and/or ischemia of the extremities is increased. Hence, concomitant use of Atzumi with strong CYP3A4 inhibitors is contraindicated. Indication Atzumi is an ergotamine derivative indicated for the acute treatment of migraine with or without aura in adults. Limitations of Use Atzumi is not indicated for the preventive treatment of migraine or for the management of hemiplegic migraine or migraine with brainstem aura. Contraindications Atzumi is not recommended in patients with: Concomitant use of strong CYP3A4 inhibitors Ischemic heart disease or coronary artery vasospasm Uncontrolled hypertension, peripheral arterial diseases, sepsis, following vascular surgery, or severe hepatic or renal impairment Hypersensitivity to ergot alkaloids Concomitant use of other 5-HT₁ agonists or ergotamine-containing or ergot-type medication within 24 hours Concomitant use of peripheral and central vasoconstrictors Warnings and Precautions Atzumi may cause: Cardiac events: Cardiac events in patients with risk factors of coronary artery diseases: Consider administration of the first dose of Atzumi under medical supervision (including the use of an electrocardiogram) Cerebrovascular events: Cerebrovascular events (eg, cerebral hemorrhage, subarachnoid hemorrhage, and stroke) have been reported, particularly with dihydroergotamine mesylate injection Vasospasm/elevated blood pressure: Dihydroergotamine may cause vasospasm or elevation in blood pressure Medication overuse headache: Detoxification may be necessary Preterm labor: Advise pregnant women of the risk Fibrotic complications: Rare cases have been reported following prolonged daily use of dihydroergotamine mesylate.
