Key clinical point: Zavegepant nasal spray was effective in the acute treatment of migraine, with favorable tolerability and safety profiles.
Major finding: At 2 hours post-dose, higher proportions of patients treated with zavegepant vs placebo were free from pain (risk difference 8.8 percentage points; P < .0001) and from their most bothersome symptom (risk difference 8.7 percentage points; P = .0012). Dysgeusia (21% vs 5%), nasal discomfort (4% vs 1%), and nausea (3% vs 1%) were the most common adverse events in the zavegepant vs placebo group.
