Key clinical point: In patients with episodic migraine (EM), erenumab reduced both monthly migraine days (MMD) and monthly migraine attacks (MMA) by a similar magnitude. However, the impact on migraine attack duration was minor.
Major finding: Erenumab 70 mg and 140 mg vs. placebo were associated with a greater reduction in MMD (least square mean percent change [LSM%], −39% and −44% vs. 22%) and MMA (LSM%, −40% and −43% vs. −26%). The percentage change from baseline in migraine attack duration was minor with erenumab 70 mg and 140 mg vs. placebo (LSM%, −7% and −8% vs. −1%).
Study details: Findings are from a post hoc analysis of phase 3 STRIVE study including 955 patients with EM who were randomly allocated to receive either erenumab 70 mg or 140 mg or placebo once monthly for 6 months.
