Key clinical point: Anti-calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAb) were effective and showed a similar time to onset in patients with chronic migraine (CM), irrespective of disease duration.
Major findings: At 10-12 months of follow-up, anti-CGRP mAb reduced monthly migraine days by an average of 12 days across all tertiles of CM duration (P = .946). Additionally, monthly headache days and acute medication use significantly decreased from baseline to 10-12 months (P < .001) across all tertiles of CM duration, indicating no difference in the time to onset of anti-CGRP mAb across tertiles.
Study details: This cohort study included 335 patients with CM treated with anti-CGRP mAb for at least 12 months. Patients were categorized into different tertiles of CM duration: 0-7 years, 8-18 years, and 18-60 years.
Disclosures: This study did not disclose any funding sources. Four authors declared receiving personal fees from or having other ties with various sources.
