Key clinical point: Both galcanezumab and rimegepant were effective as a preventive treatment for episodic migraine, with galcanezumab not being superior to rimegepant.
Major finding: Overall, 62% vs 61% of the patients receiving galcanezumab vs rimegepant achieved ≥ 50% reduction in monthly migraine headache days after 3 months, respectively, with no statistically significant difference between the groups ( P = .70). Treatment-emergent adverse events were similar between study interventions and were mostly mild or moderate in severity.
Study details: Findings are from the CHALLENGE-MIG study including 580 patients with episodic migraine with or without aura who were randomly assigned to receive galcanezumab (n = 287) or rimegepant (n = 293) for 3 months.
Disclosures: This study was funded by Eli Lilly and Company, Indianapolis, IN, USA. Eight authors declared being employees of Eli Lilly and Company. Some other authors declared ties with various sources, including Eli Lilly and Company.
