Efficacy and safety of eptinezumab in patients with migraine and self-reported aura: Post hoc analysis of PROMISE-1 and PROMISE-2

Background This post hoc subgroup analysis evaluated the efficacy and safety of eptinezumab for migraine prevention in patients with migraine and self-reported aura. Methods PROMISE-1 (NCT02559895; episodic migraine) and PROMISE-2 (NCT02974153; chronic migraine) were randomized, double-blind, placebo-controlled trials that evaluated eptinezumab for migraine prevention. In both studies, the primary outcome was the mean change from baseline in monthly migraine days over Weeks 1-12. Patients in this analysis included those who self-reported migraine with aura at screening. Results Of patients with episodic migraine, similar to 75% reported a history of aura at screening; of patients with chronic migraine, similar to 35% reported a history of aura. Changes in monthly migraine days over Weeks 1-12 were -4.0 (100 mg) and -4.2 (300 mg) with eptinezumab versus -3.1 with placebo in patients with episodic migraine with aura, and were -7.1 (100 mg) and -7.6 (300 mg) with eptinezumab versus -6.0 with placebo in patients with chronic migraine with aura. Treatment-emergent adverse events were reported by 56.0% (100 mg), 57.4% (300 mg), and 55.4% (placebo) of patients. Conclusions The preventive migraine efficacy of eptinezumab in patients in the PROMISE studies who self-reported aura was comparable to the overall study populations, demonstrating a similarly favorable safety and tolerability profile.

Automated summary

This subgroup analysis evaluated the efficacy and safety of eptinezumab for migraine prevention in patients with self-reported aura. The results showed that eptinezumab had comparable preventive efficacy for both episodic and chronic migraine patients with aura, with a similarly favorable safety and tolerability profile as the overall study populations.
