New drugs targeting calcitonin gene-related peptide for the management of migraines.

INTRODUCTION

Significant advances in migraine research have contributed to the development of new drugs for the treatment of migraine. Monoclonal antibodies (mAbs) against Calcitonin Gene-Related Peptide (CGRP) or its receptor and CGRP receptor antagonists (gepants) have been associated with a good safety profile and resulted in an overall efficacy in reducing the number of monthly migraine days both in episodic and chronic forms of migraine.

AREAS COVERED: The results from main investigation studies (phase 2 or 3) of CGRP-targeting drugs (both anti-CGRP mAbs and gepants) are reported in this expert-opinion review.

EXPERT OPINION: The introduction of new drugs targeting CGRP is a significant breakthrough in the migraine field, and represents a new generation of therapeutic agents that are available to manage migraine. The evaluation of efficacy and safety in the long-term follow-up and the development of trials comparing the available drugs could improve the current knowledge. The economic sustainability of these drugs remains to be clarified, and a cost-cutting campaign should be promoted based on the high burden of migraine.
