Key clinical point: Patients with migraine respond to preventive treatment with monoclonal antibodies targeting calcitonin gene-related peptide (anti-CGRP mAbs) irrespective of their previous failure or partial response to onabotulinumtoxinA.
Major finding: A response of 50% or higher improvement in headache (P = .395) or migraine (P = .408) frequency was not significantly different in partial or complete nonresponders to onabotulinumtoxinA.
Study details: This was a real-world prospective observational study including 155 patients with migraine who initiated preventive treatment with anti-CGRP mAbs and were partial or nonresponders to onabotulinumtoxinA.
