Background: Since 2018, several CGRP-targeted therapies have entered the migraine market, including eptinezumab. Minimal evidence exists evaluating the real-world effectiveness of switching from a subcutaneous to an intravenous anti-CGRP mAb. Methods: An observational, multi-site (n=4), US-based study, REVIEW evaluated real-world experiences of patients with chronic migraine (CM) treated with eptinezumab using a chart review, patient survey, and physician interviews. Adults (≥18 years) with a diagnosis of CM who had completed ≥2 consecutive eptinezumab infusion cycles were eligible. Results: Enrolled patients were primarily female (83%, 78/94), had a mean age of 49 years and a mean migraine diagnosis duration of 15.4 years. All patients (94/94) self-reported prior preventive therapy with 89% (84/94) reporting prior subcutaneous anti-CGRP mAb use (i.e., fremanezumab, galcanezumab, or erenumab). Regardless of prior exposure to a CGRP ligand or receptor blocker, the number of “good” days/month more than doubled following eptinezumab. Patients experienced a similar mean change in the number of “good” days/month regardless of the number and type of previous subcutaneous anti-CGRP mAb used. Conclusions: This real-world, patient survey showed that patients with prior exposure to subcutaneous anti-CGRP mAbs had high overall satisfaction with the effectiveness of eptinezumab treatment regardless of the number and type of previous therapies used.
