| Abstract: | Importance of the field: Migraine is an episodic, substantially inherited brain disorder affecting 15% of adults in Western Europe and North America, and is one of the commonest reasons for patients to see their physicians. While the World Health Organization considers that severe migraine can be as disabling as quadriplegia, unfortunately the condition remains undertreated. Until the 1990s, specific migraine therapies were limited to ergot derivatives.Areas covered in this review: The triptans, serotonin 5-HT1B/1D receptor agonists, revolutionized the acute management of migraine patients. However, although the triptans are generally effective and safe, not all patients can take them and many do not respond especially to oral therapies. Recently, progress has been made on the therapeutic front, particularly with new acute treatments. This review will focus on the therapeutic potential of ADX10059, a metabotropic glutamate receptor 5, negative allosteric modulator (mGluR5 NAM), in migraine. Data from a proof-of-concept study in episodic migraineurs demonstrated a significant improvement following acute treatment. A large European multicenter, randomized, double-blind, placebo-controlled, parallel-group, dose-ranging study is currently investigating the efficacy, safety and tolerability of the compound for migraine prevention.What the reader will gain: The reader will have the basic principles of migraine management and the potential for glutamate-targeted approaches.Take home message: Targeting glutamatergic transmission in migraine may provide a novel preventive therapy that is effective and well-tolerated. |
