Migraine is a common and debilitating neurological disorder characterized by recurrent headaches of moderate-to-severe intensity. Because of its high prevalence, migraine causes a considerable financial burden on society. There is ample evidence showing that migraine is a complex neurological disorder that involves not only the trigeminovascular and autonomic systems, but also the hypothalamus and cerebral cortex. Calcitonin gene-related peptide (CGRP) was originally discovered as a 37-amino acid neuropeptide derived from a calcitonin gene splicing variant, is enriched in trigeminal ganglion neurons. Much attention has been paid to CGRP since it was found to be released from trigeminal terminals in animal migraine models. Subsequent studies demonstrated that CGRP administration induced migraine-like headaches specifically in migraineurs, thus highlighting its pivotal role CGRP in the development of migraine attacks. Monoclonal antibodies targeting CGRP and its receptor exhibited consistent efficacy for migraine prophylaxis with excellent safety profiles in clinical trials. Furthermore, emerging data support the long-term safety and efficacy of these antibodies. On the other hand, there are several concerns that have newly surfaced in the real-world setting. In this review, the development and perspective of anti-migraine therapeutic strategies using CGRP-related antibodies are discussed.
