Key clinical point: A single dose of zavegepant nasal spray (20 or 10 mg) was effective for the acute treatment of migraine with a favorable safety profile.
Major finding: At 2 hours, a significantly higher proportion of patients treated with 20 mg or 10 mg zavegepant vs placebo reported freedom from pain (23.1% and 22.5% vs 15.5%; P = .0055 and .0113, respectively) and most bothersome symptoms (42.5% and 41.9% vs 33.7%; P = .0094 and .0155, respectively), with adverse events being mostly mild or moderate and no indications for hepatotoxicity.
Study details: This phase 2/3 trial included 1673 patients with migraine with or without aura who were randomly assigned to receive zavegepant (5, 10, 20 mg) or placebo to treat a single migraine attack of moderate-to-severe pain intensity.
