Key clinical point: Anti-calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAb) were more effective than onabotulinumtoxinA (BoNT-A) in reducing monthly headache days (MHD) in patients with chronic migraine (CM), although the safety profile of both treatments was comparable.
Major finding: Anti-CGRP mAb vs BoNT-A led to a significantly greater reduction in MHD at 6 months (adjusted mean difference ‒7.1; P < .001) and 12 months(adjusted mean difference ‒6.2; P < .001). Both treatments had favorable and comparable safety profiles.
Study details: Findings are from an observational, retrospective, multicenter, cohort study including 183 patients with CM who had at least two oral preventive treatment failures and received anti-CGRP mAb (n = 86) and BoNT-A (n = 97).
Disclosures: This study was supported by Italian Ministry of Health. Four authors declared receiving consultancy and advisory fees, travel grants, honoraria, or personal fees for participating in advisory boards, speaker panels, or clinical investigation studies from various sources.
