Key clinical point: Patients with migraine show higher treatment adherence and persistence to calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAb), specifically to galcanezumab, over standard-of-care (SOC) migraine preventive treatments.
Major finding: At 12 months of follow-up, CGRP mAb vs. SOC initiators had significantly higher mean adherence (proportion of days covered: 55.1% vs. 35.2%; P < .001) and persistence (212.5 vs. 131.9 days; P < .001). Similarly, galcanezumab vs. SOC initiators showed significantly higher adherence (63.7% vs. 33.7%; P < .001) and persistence (252.3 vs. 127.3 days; P < .001).
Study details: This retrospective, observational, claims database study created two separate 1:1 propensity-score-matched cohorts of adult patients with migraine initiating SOC or a CGRP mAb (n = 3082 pairs) and SOC or galcanezumab (n = 421 pairs).
Disclosures: The study was funded by Eli Lilly and Company. All authors declared being current/former employees or minor shareholders of Eli Lilly or a company contracted by Eli Lilly.
