Key clinical point: Zavegepant nasal spray, administered as needed for up to eight doses per month, demonstrated long-term safety in the acute treatment of migraine over 1 year.
Major finding: The most common adverse events (AE), reported in ≥5% patients receiving zavegepant, were dysgeusia, nasal discomfort, COVID-19, nausea, nasal congestion, throat irritation, and back pain. In the 1-year period, only 6.8% patients discontinued treatment due to AE; dysgeusia was the most common cause, accounting for 1.5% of discontinuations. No deaths were reported.
Study details: This phase 2/3, open-label safety study included 603 adults with moderate to severe migraine who had a history of 2 to 8 moderate to severe attacks per month and were treated with intranasal 10 mg zavegepant daily for 1 year.
Disclosures: This study was funded by Biohaven Pharmaceuticals. Some authors declared being employees of or holding stocks of or stock options in Biohaven Pharmaceuticals. Some others declared having ties with various sources, including Biohaven Pharmaceuticals.
