Recently, Gao et al. published an article titled "Monthly versus quarterly fremanezumab for the prevention of migraine: a systemic review and meta-analysis from randomized controlled trials" which concluded that monthly administration of fremanezumab led to significant reduction in monthly migraine days (MMD) when compared to quarterly fremanezumab. We have noted a critical flaw in Gao et al. meta-analysis wherein the authors have mistakenly utilized standard error values in place of standard deviation values in performing their pooled analyses. This error directly impacts the study results and conclusions. In this brief communication, we present revised analysis using correct methods. Using the correct SD values, our pooled analysis showed no significant difference in mean change from baseline in MMD between the two fremanezumab dosing regimens (P = 0.17). Furthermore, in the corrected subgroup analyses by type of migraine, there were no significant differences in mean change from baseline in MMD between monthly fremanezumab and quarterly fremanezumab (chronic migraine, P = 0.50; episodic migraine, P = 0.69). Overall, results from our corrected meta-analyses show that there is no significant difference in migraine prevention efficacy between monthly and quarterly fremanezumab dosing.

Background: The long-term safety and efficacy of fremanezumab were evaluated in a 52-week extension study (NCT02638103). Patient satisfaction with fremanezumab, dosing preferences, and patient-reported outcomes were assessed in a subpopulation who completed the extension study and consented to a follow-up questionnaire. Methods: In the extension study (N = 1842), adults with migraine were randomized to quarterly or monthly fremanezumab. After completing active treatment, patients answered a survey evaluating patient satisfaction, treatment and dosing preferences, and changes in patient-reported outcomes. Results: Of the 557 patients who could have been contacted upon completing the extension study, 302 consented and 253 completed the survey. The mean (standard deviation) satisfaction rating for fremanezumab was 6.1 (1.4; 1 = "extremely dissatisfied" to 7 = "extremely satisfied"). Most patients (175 [69.2%]) preferred quarterly over monthly fremanezumab dosing. Among patients taking antiepileptics (most common class of prior preventive medication; n = 130), 91.5% preferred fremanezumab. Patients reported improvements in anxiety (74 [67.9%]), sleep quality (143 [56.5%]), and quality of time spent with others (210 [83.0%]) with fremanezumab. Conclusion: In this study, treatment satisfaction with fremanezumab was high, most patients preferred quarterly fremanezumab dosing, and fremanezumab was generally preferred to prior preventive medications.
