Rapid effectiveness of eptinezumab to treat ongoing migraine attacks: preliminary data from an Italian multicenter real-world experience (the BE-FREE study)

Year: 2026

Type: article

Abstract: Introduction: Eptinezumab is an intravenous anti-calcitonin gene-related peptide (CGRP) monoclonal antibody (mAb) approved for the prevention of episodic and chronic migraine. We aimed to explore the earliest changes in migraine pain intensity and associated symptoms during the first 30 min of eptinezumab infusion in a real-world setting, particularly when an acute migraine attack was ongoing. Methods: The BE-FREE study is an ongoing Italian observational, multicenter, independent, real-world, and prospective study. We enrolled patients affected with episodic migraine (EM) and chronic migraine (CM) who were experiencing an ongoing migraine attack. Eptinezumab was administered within 1-12 h of the onset of the qualifying migraine attack. Data collected included monthly migraine days (MMDs), headache pain intensity, the number of monthly acute medications, and the use of concomitant or past standard preventive treatments (SPTs). The Numerical Rating Scale (NRS), associated symptoms, and pain freedom (PF) were recorded before infusion (T0) and at intervals of 10 (T10), 20 (T20), and 30 (T30) min during infusion. Results: = 0.046) compared with T0. PF was reported by 6.5% of patients at T10, 19.4% at T20, 29.0% at T30, and 19.4% at T60, T90, and T120. Discussion: The BE-FREE study results, representing the first real-world evidence, demonstrate the rapid effect of eptinezumab during the first 30 min of infusion in patients experiencing an ongoing migraine attack.
