Read MoreHide Full Article

Impel NeuroPharma, Inc. announced that the FDA has approved its lead product, Trudhesa nasal spray (0.725 mg per spray), for the acute treatment of migraine in adult patients with or without aura. The product is expected to be launched early next month.

The new drug application for Trudhesa was based on data from the phase III STOP 301 study. The primary goal of the study was to assess the safety and tolerability of Trudhesa. Data form the same showed that treatment with Trudhesa was generally well tolerated, and exploratory efficacy findings showed that it provided rapid, sustained and consistent symptom relief.

Data from the study showed that treatment with Trudhesa led to consistent efficacy even when taken late into a migraine attack, unlike other oral acute treatments that need to be taken within one hour of the attack to be most effective. There was no serious treatment-emergent adverse event reported in the STOP 301 study.

Per the company, following the FDA nod, Trudhesa became the first and only therapeutic to use precision olfactory delivery technology to deliver dihydroergotamine mesylate to the vascular-rich upper nasal space.

Shares of Impel have rallied 76.3% in the past three months compared with the industry’s rise of 2.1%.
