A systematic review with expert opinion on the role of gepants for the preventive and abortive treatment of migraine.

Expert Rev Neurother 2022 Jun 27:1-20. Epub 2022 Jun 27.

Department of Neurosciences, Biomedicine and Movement Sciences, University of Verona, Verona, Italy.

Introduction: Gepants are small molecules targeting the calcitonin gene-related peptide (CGRP) that have been recently introduced and are under additional clinical development as preventive and abortive treatment options for migraine.

Areas Covered: After providing a narrative overview of current preventive and acute treatment options for migraine and summarizing the pathophysiology of migraine attack and the role of CGRP, we performed a systematic review, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations, on trials on gepants in preventive and acute treatment of migraine. Studies and results were reviewed and discussed, and expert opinion was presented. Read More

Calcitonin gene-related peptide in migraine: from pathophysiology to treatment.

Neurologia (Engl Ed) 2022 Jun 26;37(5):390-402. Epub 2021 May 26.

Unidad de Cefalea, Servicio de Neurología, Hospital Universitari Vall d'Hebron, Barcelona, Spain; Grupo de Investigación en Cefalea, VHIR, Universitat Autònoma de Barcelona, Barcelona, Spain.

Introduction: It has been observed in recent years that levels of such molecules as calcitonin gene-related peptide (CGRP) and, to a lesser extent, the pituitary adenylate cyclase-activating peptide are elevated during migraine attacks and in chronic migraine, both in the cerebrospinal fluid and in the serum. Pharmacological reduction of these proteins is clinically significant, with an improvement in patients' migraines. It therefore seems logical that one of the main lines of migraine research should be based on the role of CGRP in the pathophysiology of this entity. Read More

Ex vivo Release of Calcitonin Gene-Related Peptide from the Trigeminovascular System in Rodents.

J Vis Exp 2022 05 16(183). Epub 2022 May 16.

Danish Headache Center, Department of Neurology, Rigshospitalet, University of Copenhagen;

Calcitonin gene-related peptide (CGRP) was first discovered in the 1980s as a splice variant from the calcitonin gene. Since its discovery, its role in migraine pathophysiology has been well established, first by its potent vasodilator properties and subsequently by its presence and function as a neurotransmitter in the sensory trigeminovascular system. The migraine-provoking ability of CGRP gave support to the pharma industry to develop monoclonal antibodies and antagonists inhibiting the effect of CGRP. Read More

Effectiveness of Transcranial Direct Current Stimulation and Monoclonal Antibodies Acting on the CGRP as a Combined Treatment for Migraine (TACTIC): Protocol for a Randomized, Double-Blind, Sham-Controlled Trial.

Front Neurol 2022 10;13:890364. Epub 2022 May 10.

Department of Biotechnological and Applied Clinical Sciences, University of L'Aquila, L'Aquila, Italy.

Background: Migraine is a recurrent headache disorder that has a still unclear pathophysiology, involving several circuits of both the central and peripheral nervous system. Monoclonal antibodies acting on the calcitonin gene-related (CGRP) pathway (CGRP-MAbs) are the first drugs specifically designed for migraine; those drugs act peripherally on the trigeminal ganglion without entering the blood-brain barrier. Conversely, neuromodulation techniques such as transcranial direct current stimulation (tDCS) act centrally by increasing or decreasing the neuronal firing rate of brain cortical areas. Read More

Front Pain Res (Lausanne) 2022 1;3:858709. Epub 2022 Apr 1.

Koç University Research Center for Translational Medicine, Istanbul, Turkey.

Background: After the acute pandemic of coronavirus disease 2019 (COVID-19), a wide variety of symptoms are identified under the term post-COVID syndrome, such as persistent headache. Post-COVID headache can be presented in a broad spectrum like headache attributed to systemic infection, chronification of already existing primary headache, or long-lasting, and also late-onset new daily persistent headache.

The Arrival of Anti-CGRP Monoclonal Antibodies in Migraine.

Neurotherapeutics 2022 Apr 14. Epub 2022 Apr 14.

Department of Neurology, Jefferson Headache Center, Thomas Jefferson University, 900 Walnut Street, Suite 200, Philadelphia, PA, 19107, USA.

Remarkable advancements have been made in the field of migraine pathophysiology and pharmacotherapy over the past decade. Understanding the molecular mechanism of calcitonin gene-related peptide (CGRP) has led to the discovery of a novel class of drugs, CGRP functional blocking monoclonal antibodies (mAbs), for migraine prevention. CGRP is a neuropeptide inherently involved in migraine physiology where its receptors are found dispersed throughout the central and peripheral nervous systems. Read More

Changes in Plasma Lipid Levels Following Cortical Spreading Depolarization in a Transgenic Mouse Model of Familial Hemiplegic Migraine.

Metabolites 2022 Mar 1;12(3). Epub 2022 Mar 1.

Department of Human Genetics, Leiden University Medical Center, 2333 ZC Leiden, The Netherlands.

Metabolite levels in peripheral body fluids can correlate with attack features in migraine patients, which underscores the potential of plasma metabolites as possible disease biomarkers. Migraine headache can be preceded by an aura that is caused by cortical spreading depolarization (CSD), a transient wave of neuroglial depolarization. We previously identified plasma amino acid changes after CSD in familial hemiplegic migraine type 1 (FHM1) mutant mice that exhibit increased neuronal excitability and various migraine-related features.

Calcitonin gene-related peptide-targeting drugs for migraine: how pharmacology might inform treatment decisions.

Lancet Neurol 2022 03 31;21(3):284-294. Epub 2022 Jan 31.

Erasmus MC, University Medical Center Rotterdam, Division of Vascular Medicine and Pharmacology, Department of Internal Medicine, Rotterdam, Netherlands. Electronic address:

Migraine is the second most disabling disorder across all age groups worldwide. Since 2018, two classes of drugs that inhibit the actions of calcitonin gene-related peptide (CGRP), which is implicated in migraine pathophysiology, have become available: gepants (CGRP receptor antagonists) and monoclonal antibodies directed against CGRP or its receptor. Despite phase 3 clinical trials and some real world evidence, knowledge of the pharmacology and related clinical effects of these drugs is low, and trial data are not necessarily generalisable to all populations.

The role of TRP ion channels in migraine and headache.

Neurosci Lett 2022 01 30;768:136380. Epub 2021 Nov 30.

Headache Center and Clinical Pharmacology Unit, Careggi University Hospital, Florence, Italy. Electronic address:

Migraine afflicts more than 10% of the general population. Although its mechanism is poorly understood, recent preclinical and clinical evidence has identified calcitonin gene related peptide (CGRP) as a major mediator of migraine pain. CGRP, which is predominantly expressed in a subset of primary sensory neurons, including trigeminal afferents, when released from peripheral terminals of nociceptors, elicits arteriolar vasodilation and mechanical allodynia, a hallmark of migraine attack.
