Real-World Clinical Effectiveness and Migraine-Related Healthcare Resource Utilization in Patients Initiating Fremanezumab in Germany and the United Kingdom.

PURPOSE: Fremanezumab, a humanized monoclonal antibody targeting calcitonin gene-related peptide, is approved in Germany and the United Kingdom (UK) for patients experiencing migraine ≥4 days per month, and it is reimbursed for patients where ≥4-5 (Germany) or ≥3 (UK) prior migraine preventive treatments have failed. We evaluated real-world clinical effectiveness and healthcare resource utilization (HCRU) in patients initiating fremanezumab in Germany and the UK.

METHODS

This non-interventional, retrospective, physician panel-based, online, multicenter chart review study included adult patients with chronic migraine (CM) or episodic migraine (EM) with first fremanezumab treatment initiation (index date) from June 2019 or later (Germany), and from June 2020 or later (UK). Changes in monthly migraine days (MMD), monthly headache days (MHD), and disability outcomes (Migraine Disability Assessment [MIDAS] and Headache Impact Test-6 [HIT-6]) were evaluated from baseline (pre-index) to 3 months post-index, and changes in HCRU were evaluated from 6 months pre-index to 6 months post-index.

RESULTS

The study population included 207 German and 183 UK patients (CM, 48.3% and 95.1%; monthly dosing, 59.4% and 51.9%, respectively). Reductions in MMD and MHD were observed in the German cohort (percent reductions: 60.2% and 55.1%, respectively) and the UK cohort (51.9% and 47.3%, respectively; all p < 0.001 vs baseline). Reductions in mean MIDAS and HIT-6 scores (all p < 0.01 vs baseline), outpatient office visits, urgent care/emergency room visits, and inpatient admissions were also observed (all p < 0.05 vs baseline) for both countries.

CONCLUSION

Fremanezumab demonstrated real-world clinical effectiveness in German and UK cohorts and may decrease the burden of migraine for patients and providers.
