Key clinical point: A second dose of eptinezumab may be beneficial in patients with migraine who exhibit a suboptimal first-dose response.
Major finding: Percent change in monthly migraine days (MMD) over weeks 1-12 (PROMISE-1: odds ratio [OR] 0.97; P = .0001; PROMISE-2: OR 0.94; P < .0001) and change in 6-item Headache Impact Test total score (only PROMISE-2: OR 0.92; P = .027) were observed to be significant first-dose predictors of second-dose response.
Study details: This post hoc analysis included patients with migraine (episodic [n = 416; PROMISE-1] and chronic [n = 479; PROMISE-2]), suboptimal response (<50% reduction from baseline in MMD across weeks 1-12), and patient-reported outcome data at weeks 12 and 24.
