Abstract

Background

The outcome of migraine patients retreated with monoclonal antibodies (mAbs) targeting the calcitonin gene-related peptide (anti-CGRP) or its receptor (anti-CGRPr) is not completely known.

Methods

This multicentric prospective observational cohort study assessed monthly migraine days (MMDs), migraine acute medication intake (MAMI), and HIT-6 at baseline, after 90–112 days (Rev-1), after 84–90 days since Rev-1 (Rev-2) and 30 days after the last injection of anti-CGRP/CGRPr mAbs (Year-end), in the first and the second year after a discontinuation period.

Results

We enrolled 226 patients (79.6% with chronic migraine; 55.3% on erenumab and 44.7% on galcanezumab or fremanezumab). MMDs, MAMI, and HIT-6—did not differ at the respective first and second-year evaluations in the entire cohort, and comparing anti-CGRP with anti-CGRPr Abs. MMDs (18.1 ± 7.8 vs. 3.4 ± 7.8), MAMI (26.7 ± 28.3 vs.17.7 ± 17.2), and HIT-6 scores (63.1 ± 5.9 vs. 67.1 ± 10.3) were lower in the second year than in the pre-treatment baseline (consistently, p < 0.0001). Second-year baseline MMDs were lower in patients on anti-CGRP mAbs (p = 0.001) and with lower pre-treatment baseline MMDs (p ≤ 0.001).

Conclusion

Anti-CGRP/CGRPr mAbs are effective in the second as in the first year. The use of anti-CGRP or CGRPr mAbs influenced the second-year baseline MMDs, but their effectiveness did not differ during the two treatment years.
