Key clinical point: Monthly erenumab demonstrated promising short-term clinical effectiveness in patients with difficult-to-treat chronic migraine; however, less than one-fourth of the patients sustained efficacy over 2 years.
Major finding: The monthly migraine days (MMD) reduced significantly after 6 months of erenumab treatment (mean reduction [MR] 7.5 days; P < .001), with 48% of patients achieving ≥30% reduction in MMD. At months 12 and 24, 38% and 23% of patients remained ≥30% responders, respectively.
Study details: Findings are from a 2-year real-world prospective analysis of a clinical audit including 160 patients with difficult-to-treat chronic migraine who failed an average of 8.3 preventive treatments and received monthly erenumab.
Disclosures: This study did not receive any funding. Three authors declared receiving honoraria for speaking or participation in advisory boards or funding for travel from various sources.
