FDA Approves Atzumi Nasal Powder for Acute Migraine Treatment

The US Food and Drug Administration (FDA) has approved Atzumi, a 5.2 mg dihydroergotamine (DHE) nasal powder, for the acute treatment of migraine with or without aura in adults. Developed by Satsuma Pharmaceuticals, Atzumi is the first and only DHE nasal powder and uses the SMART platform for simplified drug delivery.

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.
