Key clinical point: Calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAb) were more effective than onabotulinumtoxinA in patients with chronic migraine (CM), even in those who were difficult-to-treat (DTT) and did not respond to ≥3 preventive treatments.
Major finding: At 6 months, CGRP mAb vs onabotulinumtoxinA significantly reduced monthly migraine days (−13.0 vs −8.7 days/month; P < .001) in overall populations, with a similar reduction observed in those who were DTT (−13.0 vs −9.1 days/month; P < .001). Both treatments were well tolerated, with no treatment discontinuation being observed because of adverse events.
Study details: This multicenter, real-world study included 316 and 333 patients with CM who received ≥1 dose of CGRP mAb and onabotulinumtoxinA, respectively, and of whom 544 were DTT and had failed to respond ≥3 preventive treatments.
Disclosures: This study was funded by Taiwan National Science and Technology Council and others. Three authors declared receiving research grants, personal fees as advisors or speakers, or honoraria as speakers from various sources.
