Objective These pooled analyses evaluated the safety and efficacy of fremanezumab in racial and ethnic subgroups.

Background The prevalence, severity, and burden of migraine differ by geographic region and across different racial and ethnic groups. Fremanezumab, a fully humanized monoclonal antibody (IgG2Δa) that selectively targets calcitonin gene-related peptide (CGRP), has proven efficacy for migraine prevention in adults.

Design/Methods These pooled analyses included data from 3 clinical trials (HALO episodic migraine [EM], HALO chronic migraine [CM], and FOCUS [EM/CM with inadequate response to 2-4 prior preventive classes]), in which patients were randomized to 12 weeks of double-blind treatment with quarterly fremanezumab, monthly fremanezumab, or matched placebo. These pooled analyses assessed changes from baseline in monthly migraine days (MMD), proportion of patients with 50% or greater reduction in MMD from baseline, and adverse events (AEs) based on patients’ racial/ethnic groups.

Results This pooled population included 2,842 patients. Across White and Non-white racial/ethnic group, quarterly and monthly fremanezumab provided reductions in MMD from baseline during 12 weeks vs placebo (White, −4.6 and −4.8 vs −2.4, P<0.0001; Non-white, −4.8 and −4.5 vs −3.3, P<0.05 [Black/African American, −4.5 and −3.6 vs −3.9; Asian, −3.3 and −3.6 vs −0.9, P<0.05; Other, −4.6 and −5.7 vs −2.7]), as well as increases in the proportion of patients with 50% or greater reduction in MMD versus placebo. In the quarterly fremanezumab, monthly fremanezumab, and placebo groups, respectively, ≥1 AE was reported by 64%, 62%, and 59% of White patients and 66%, 61%, and 53% of Non-white patients (Black/African American patients, 60%, 58%, and 54%; Asian patients, 64%, 62%, and 44%; Other, 85%, 68%, and 81%).

Conclusions Treatment with fremanezumab was safe and effective, based on reductions in MMD and increases in ≥50% response rates versus placebo, across White and Non-white racial/ethnic groups, including the Asian subgroup.
