Changes in use of acute and preventive medications for migraine after erenumab initiation over 12 months: A United States retrospective cohort study.
Objective: To assess changes in real-world use of acute and preventive medications for migraine over a 12-month follow-up period in the United States following initiation of the anti-calcitonin gene-related peptide (CGRP) pathway monoclonal antibody (mAb) erenumab.
Background: Early assessments of real-world use of acute and preventive medications for migraine after initiation of erenumab have been limited to 6 months of follow-up.
Methods: This retrospective cohort study used data from the IQVIA open-source longitudinal prescription (LRx) and medical (Dx) claims databases. Adult patients with an initial claim (index date) for erenumab between May 2018 and April 2020 were identified.
Results: Among 201,176 patients who met inclusion criteria, the mean (standard deviation [SD]) age was 47.5 (13.8) years and 85.6% (n = 172,153) were female. Most patients used one or more acute (88.4%; n = 177,795) and one or more traditional preventive (86.1%; n = 173,225) medications during the 12-month pre-index period. Adherence to erenumab (proportion of days covered [PDC] ≥0.80) was 40.2% (n = 80,927) with an overall mean (SD) PDC of 0.60 (0.34). Among all patients, 70.0% (n = 140,809) discontinued erenumab. After accounting for 24.7% (n = 49,720) of patients who restarted erenumab, discontinuation without reinitiation was observed in 45.3% (n = 91,089) of total patients. Switching to a different anti-CGRP pathway mAb was observed in 13.1% (n = 26,446) of total patients. Among 177,795 patients with pre-index use of one or more acute migraine medication class, 86.5% (n = 153,788) had post-index use of the same class, and 56.7% (87,134/153,788) of them discontinued one or more class of acute medication in the 12-month follow-up period. Similarly, among 173,225 patients with pre-index use of one or more traditional migraine preventive medication class, 67.7% (n = 117,274) had post-index use of the same class, and 46.7% (54,790/117,274) of them discontinued one or more class of traditional preventive medication in the 12-month follow-up period.
Conclusions: In this long-term study, we observed the discontinuation of both acute and preventive medications for migraine post-erenumab initiation.
