ABSTRACT: Introduction
The prevalence of migraine is highest among working age individuals, and this disease is associated with an increased number of sick leaves and health care visits, as well as lost productivity. Erenumab, the first monoclonal antibody targeting the calcitonin gene-related peptide (CGRP) pathway, is effective in decreasing the monthly number of migraine days, but evidence of its impact on the number of sick leave days and health care visits in patients with migraine is limited.Methods
This retrospective registry study focused on occupationally active patients with migraine treated with erenumab at a Finnish private health care provider, Terveystalo. Erenumab responders, defined as patients who had at least two unique prescriptions of erenumab and no prescription of other CGRP inhibitor (CGRPi), were followed for 12 months prior to and after erenumab treatment initiation (index), and the change in the number of headache-related and all-cause sick leave days, health care visits and prescriptions for other medications during this period were assessed from the registry data. The same outcomes were assessed in an age- and sex-matched control group of migraine patients not receiving CGRPi to control for potential changes in patient behavior and health care practices during the COVID-19 pandemic.Results
Altogether, 162 patients who were entitled to employer-sponsored health care received erenumab and met the 12-month follow-up requirements. In the responder group (n = 82; 50.1%) headache-related sick leave days were reduced by 73.9% (p = 0.035) and health care visits by 44.6% (p < 0.001) in the 12 months following treatment initiation compared to the period of 12 months prior to treatment. All-cause sick leave days were reduced by 19.4% and all-cause health care visits by 13.5%, but these changes were not statistically significant. Triptan prescriptions decreased by 30.4% (p = 0.012) and other prophylactic treatments by 31.5% (p = 0.004). No significant changes were observed in the corresponding outcomes in the migraine control group during the same period.Conclusions
The results of this registry study suggest that in addition to the effect on the monthly number of migraine days documented in clinical trials, erenumab can significantly reduce the number of headache-related sick leave days and health care visits in employed patients with migraine managed in routine clinical practice.
