Abstract: Background and Objectives: Despite decreasing prevalence of migraine with advancing age, there remains a significant proportion of individuals aged ≥65 years with migraine. Treatment of this population is difficult and they are often excluded from clinical trials, limiting evidence regarding migraine treatment outcomes. Our objective is to assess the efficacy and tolerability of anti-calcitonin gene-related peptide (CGRP) monoclonal antibody (mAb) therapies (erenumab, fremanezumab, and galcanezumab) in patients ≥65 years (O65) compared with patients <65 (U65) with daily or nondaily migraine. Methods: This observational study uses retrospective data from the electronic medical records of patients who were treated with an anti-CGRP mAb between June 2018 and November 2021. Efficacy was determined through a reduction in monthly migraine days (MMDs) and Headache Impact Test (HIT-6) scores from baseline to posttreatment. Tolerability was examined through the number of adverse events reported per group. Mann-Whitney tests were used to compare the efficacy and tolerability of U65 and O65 patients overall and separated into daily and nondaily migraine groups. Results: = 0.008). Side effects were reported (829/3,011), with a higher incidence in the U65 (22% O65, 28% U65). The most common side effects for both groups were injection site reaction/rash (40%) and constipation (25%). Discussion: This retrospective analysis provides real-world evidence that there is no difference in the efficacy and tolerability of treatment with erenumab, fremanezumab, and galcanezumab in patients O65 when compared with patients U65 both with daily or nondaily migraine. These data may help guide the choice of migraine treatment in older populations.
