Novel targets in headache: A narrative review
Abstract
Objectives/background: This narrative review summarizes novel applications for the use of calcitonin gene-related peptide (CGRP)-targeted therapies that go beyond migraine, the latest updates with respect to targeting pituitary adenylate cyclase-activating peptide (PACAP) as therapeutic in migraine, as well as exploring other more recently discovered targets that are undergoing preclinical through advanced clinical development, for the prevention and treatment of headache disorders. Headache disorders affect over one billion individuals worldwide and represent a major public health burden. Although CGRP-targeted therapies have transformed migraine care, a substantial proportion of patients do not achieve adequate relief or remain untreated. Therefore, there is the need to identify and validate novel mechanistic targets across the full spectrum of headache disorders.
Methods: This narrative review reports preclinical and clinical evidence for emerging therapeutic targets in headache, with a focus on those presented at the 2025 Scottsdale meeting of the American Headache Society, during the Advanced Science session. Literature searches were performed on specific topic areas using PubMed/Scopus to find relevant peer-reviewed literature, as well as studies in ongoing clinical trial registries.
Results: In addition to their established efficacy in migraine, CGRP-targeted therapies are increasingly being explored across other headache disorders, reflecting their broader relevance…
