SEATTLE — Impel NeuroPharma recently announced that the U.S. Food and Drug Administration (FDA) approved TRUDHESA (dihydroergotamine mesylate) nasal spray (0.725 mg per spray) for the acute treatment of migraine with or without aura in adults. TRUDHESA was previously known as INP104.

Using Impel’s proprietary Precision Olfactory Delivery (POD) technology, TRUDHESA gently delivers dihydroergotamine mesylate (DHE)—a proven, well-established therapeutic—quickly to the bloodstream through the vascular-rich upper nasal space. TRUDHESA bypasses the gut and potential absorption issues, offering rapid, sustained, and consistent symptom relief without injection or infusion, even when administered hours after the onset of a migraine attack.²The Commercial launch of TRUDHESA is planned for early October 2021.

“We are delighted with the approval of TRUDHESA and are proud to offer the millions of Americans with migraine a non-oral, acute treatment option that may provide rapid, sustained, and consistent relief, even when taken late into a migraine attack,” said Adrian Adams, Chairman and Chief Executive Officer of Impel NeuroPharma. “The approval of TRUDHESA marks the culmination of more than a decade of research and advanced engineering to pair the proven efficacy of DHE with our innovative POD technology. We are grateful for all the patients and investigators who participated in our clinical trials and who were instrumental in bringing this needed advancement to the migraine community.”
