Key clinical point: Rimegepant orally disintegrating tablet (ODT) offers pain relief within 2 hours of treatment in adults with migraine, with a tolerable safety profile.
Major finding: At 2 hours post dose, rimegepant was more effective than placebo in providing freedom from pain (risk difference 7.6; P = .0004) and the most bothersome symptom (risk difference 16.2; P < .0001). The overall rates of treatment-emergent adverse events were comparable between the rimegepant and placebo groups (15.2% and 16.4%, respectively).
Study details: This subgroup analysis of a double-blind, randomized, placebo-controlled phase 3 clinical trial included 1075 patients with acute migraine with or without aura (age ≥ 18 years) who were randomly assigned to receive either 75 mg rimegepant ODT (n = 538) or placebo (n = 537).
Disclosures: This study was funded by BioShin, a wholly owned subsidiary of Biohaven Pharmaceuticals, which was acquired by Pfizer. Pfizer provided writing support.
