It is now well evidenced that calcitonin gene-related peptide (CGRP) receptor signaling plays a key role in migraine pathophysiology. Dimos-Dimitrios Mitsikostas, MD, PhD, National & Kapodistrian University of Athens, Athens, Greece, gives an overview of the CGRP story so far in preventive migraine treatment. Prior to the develop of agents targeted against the CGRP pathway, all available treatments for patients with migraine were repurposed agents. When the causal role of CGRP was established, agents targeting CGRP ligands were tested in clinical trials, but failed due to safety. Anti-CGRP monoclonal antibodies were then developed which were found to be efficient in the prevention of episodic and chronic migraine, while avoiding many of the side effects of earlier agents. Representing the first migraine-specific agents available, these therapeutics have achieved exciting results in clinical trials to date. This interview took place during the European Academy of Neurology 2021 congress.
