Migraine Progression: A Systematic Review.

Headache 2018 Dec 27. Epub 2018 Dec 27.

Department of Neurology, Albert Einstein College of Medicine, Bronx, NY, USA.

Background: Migraine is a common and often debilitating neurological disease. It can be divided into episodic and chronic subforms based on the number of monthly headache days. Because only a subset of individuals with episodic migraine (EM) progress to chronic migraine (CM) over any given time period, understanding the factors that predict the new onset of CM or "migraine progression" may provide insights into the mechanisms, pathophysiology, prevention, and treatment of CM.

Perampanel inhibits calcitonin gene-related peptide release from rat brainstem in vitro.

J Headache Pain 2018 Nov 12;19(1):107. Epub 2018 Nov 12.

Institute of Pharmacology, Fondazione Policlinico Universitario A. Gemelli IRCSS, Roma - Università Cattolica del Sacro Cuore, Largo Francesco Vito 1, 00168, Rome, Italy.

Background: Perampanel is a novel antiepileptic drug acting via non-competitive antagonism on glutamatergic AMPA receptors, and the subsequent inhibition of ion calcium influx. Since it was recently postulated that the antagonists of glutamate receptors might play a role in the treatment of migraine, in this study we investigated the putative anti-migraine activity of perampanel in an in vitro animal model involving the static incubation of rat brainstem explants and the subsequent measurement of immune-reactive calcitonin gene-related peptide released into the incubation medium.

Methods: Acute rat brainstem explants were incubated in plain medium or in medium containing graded concentrations of perampanel. Read More

Migraine and cluster headache - the common link.

J Headache Pain 2018 Sep 21;19(1):89. Epub 2018 Sep 21.

Department of Neurogeriatric Medicine, Headache Medical Center Linz, Ordensklinikum Linz Barmherzige Schwestern, Seilerstaette 4, 4010, Linz, Austria.

Although clinically distinguishable, migraine and cluster headache share prominent features such as unilateral pain, common pharmacological triggers such glyceryl trinitrate, histamine, calcitonin gene-related peptide (CGRP) and response to triptans and neuromodulation. Recent data also suggest efficacy of anti CGRP monoclonal antibodies in both migraine and cluster headache. While exact mechanisms behind both disorders remain to be fully understood, the trigeminovascular system represents one possible common pathophysiological pathway and network of both disorders.

Antigens and Antibodies in Disease With Specifics About CGRP Immunology.

Headache 2018 Nov 5;58 Suppl 3:230-237. Epub 2018 Sep 5.

Department of Neurology, University of Minnesota Medical School, Minneapolis, MN, USA.

Growth in knowledge about calcitonin gene-related peptide (CGRP) in the pathophysiology of migraine brought CGRP antagonism to headache medicine. Failures in development of small molecule CGRP receptor antagonists and increasing knowledge and use of monoclonal antibodies (mAbs) in medicine led to the breakthrough development of large molecule anti-CGRP mAbs: eptinezumab, erenumab, fremanezumab, and galcanezumab. This specifics about CGRP immunology aims to outline: (1) knowledge needed for CGRP antagonism and (2) developmental issues of specific CGRP antagonists for provider use. Read More

Authors:
Uwe Reuter

Headache 2018 May;58 Suppl 1:48-59

Charité - Universitätsmedizin Berlin, Charitéplatz 1, 10117 Berlin, Germany.

Monoclonal antibodies targeting the calcitonin gene-related peptide pathway represent a new class of mechanism-specific, migraine-targeted therapies available for migraine prevention. To date, four monoclonal antibodies have demonstrated efficacy in phase II and III trials, significantly reducing migraine days per month versus placebo with rapid onset of action. While their efficacy may be considered similar to existing preventive options, their true value may lie in an improved tolerability profile, with high specificity and selectivity for the calcitonin gene-related peptide receptor or ligand reducing the potential for off-target binding and toxicity.

CGRP as the target of new migraine therapies - successful translation from bench to clinic.

Nat Rev Neurol 2018 Jun;14(6):338-350

Department of Clinical Sciences, Division of Experimental Vascular Research, Lund University, Lund, Sweden.

Treatment of migraine is on the cusp of a new era with the development of drugs that target the trigeminal sensory neuropeptide calcitonin gene-related peptide (CGRP) or its receptor. Several of these drugs are expected to receive approval for use in migraine headache in 2018 and 2019. CGRP-related therapies offer considerable improvements over existing drugs as they are the first to be designed specifically to act on the trigeminal pain system, they are more specific and they seem to have few or no adverse effects.

Chronic migraine: A process of dysmodulation and sensitization.

Authors:
Min Su Shengyuan Yu

Mol Pain 2018 Jan-Dec;14:1744806918767697. Epub 2018 Apr 12.

1 Department of Neurology, Chinese PLA General Hospital, Beijing, China.

Chronic migraine is a common chronic daily headache featured by frequent headache attacks with at least 15 headache days per month, which brings great disease burden to both the sufferers and the society. Transformed from episodic migraine, the pathophysiology of chronic migraine is not fully understood, even though several risk factors have been associated with migraine progression. Recent studies have identified both structural and functional alterations in some brain regions of chronic migraine patients indicating that maladaptation of the top-down pain modulation and subsequent sensitization of trigeminal system may be important in the pathogenesis of chronic migraine.

The big CGRP flood - sources, sinks and signalling sites in the trigeminovascular system.

Authors:
Karl Messlinger

J Headache Pain 2018 Mar 12;19(1):22. Epub 2018 Mar 12.

Institute of Physiology and Pathophysiology, Friedrich-Alexander-Universität Erlangen-Nürnberg, Universitätsstr. 17, 91054, Erlangen, Germany.

Background: Calcitonin gene-related peptide (CGRP) has long been a focus of migraine research, since it turned out that inhibition of CGRP or CGRP receptors by antagonists or monoclonal IgG antibodies was therapeutic in frequent and chronic migraine. This contribution deals with the questions, from which sites CGRP is released, where it is drained and where it acts to cause its headache proliferating effects in the trigeminovascular system.

Results: The available literature suggests that the bulk of CGRP is released from trigeminal afferents both in meningeal tissues and at the first synapse in the spinal trigeminal nucleus. Read More

Migraine is a highly disabling neurological condition, and preventative treatment still remains problematic, due to aspecificity of the majority of the currently available prophylactic drugs. Calcitonin-gene-related peptide (CGRP) plays a crucial role in migraine pathophysiology; agents aimed at blocking its activity have, therefore, been developed in recent years, among which are monoclonal antibodies (mAbs) against CGRP, to prevent migraine. Erenumab is the only mAb that targets the CGRP receptor instead of the ligand, with high specificity and affinity of binding. Read More

Side effects associated with current and prospective antimigraine pharmacotherapies.

Expert Opin Drug Metab Toxicol 2018 Jan 15;14(1):25-41. Epub 2017 Dec 15.

d Departamento de Farmacobiología , Cinvestav-Coapa , Ciudad de México , México.

Introduction: Migraine is a neurovascular disorder. Current acute specific antimigraine pharmacotherapies target trigeminovascular 5-HT, 5-HT and CGRP receptors but, unfortunately, they induce some cardiovascular and central side effects that lead to poor treatment adherence/compliance. Therefore, new antimigraine drugs are being explored. Read More

Nociceptive blink reflex habituation biofeedback in migraine.

Funct Neurol 2017 Jul/Sep;32(3):123-130

Reduced habituation of the nociceptive blink reflex (NBR) is considered a trait marker for genetic predisposition to migraine. In this open-label randomized controlled study, we aimed to test the efficacy of a biofeedback training based on learning of habituation of the NBR (NBR biofeedback) compared with pharmacological (topiramate) treatment and NBR biofeedback plus topiramate treatment in a cohort of migraine without aura patients eligible for prophylaxis. Thirty-three migraine patients were randomly assigned to three months of treatment with: 1) NBR biofeedback, 2) NBR biofeedback plus topiramate 50 mg (b. Read More

Recognizing the role of CGRP and CGRP receptors in migraine and its treatment.

Cephalalgia 2017 Jan 1:333102417736900. Epub 2017 Jan 1.

1 Department of Clinical Experimental Research, Glostrup Research Institute, Rigshospitalet, Glostrup, Denmark.

Premise The brain and the sensory nervous system contain a rich supply of calcitonin gene-related peptide (CGRP) and CGRP receptor components. Clinical studies have demonstrated a correlation between CGRP release and acute migraine headache that led to the development of CGRP-specific drugs that either abort acute attacks of migraine (gepants) or are effective as prophylaxis (antibodies). However, there is still much discussion concerning the site of action of these drugs. Read More

Triptans and CGRP blockade - impact on the cranial vasculature.

J Headache Pain 2017 Oct 10;18(1):103. Epub 2017 Oct 10.

Danish Headache Center and Department of Neurology, Rigshospitalet Glostrup, Faculty of Health and Medical Sciences, University of Copenhagen, Copenhagen, Denmark.

The trigeminovascular system plays a key role in the pathophysiology of migraine. The activation of the trigeminovascular system causes release of various neurotransmitters and neuropeptides, including serotonin and calcitonin gene-related peptide (CGRP), which modulate pain transmission and vascular tone. Thirty years after discovery of agonists for serotonin 5-HT and 5-HT receptors (triptans) and less than fifteen after the proof of concept of the gepant class of CGRP receptor antagonists, we are still a long way from understanding their precise site and mode of action in migraine.

Department of Anesthesia, Critical Care & Pain Medicine, Beth Israel Deaconess Medical Center, Boston, Massachusetts 02215,

Calcitonin gene-related peptide (CGRP), the most abundant neuropeptide in primary afferent sensory neurons, is strongly implicated in the pathophysiology of migraine headache, but its role in migraine is still equivocal. As a new approach to migraine treatment, humanized anti-CGRP monoclonal antibodies (CGRP-mAbs) were developed to reduce the availability of CGRP, and were found effective in reducing the frequency of chronic and episodic migraine. We recently tested the effect of fremanezumab (TEV-48125), a CGRP-mAb, on the activity of second-order trigeminovascular dorsal horn neurons that receive peripheral input from the cranial dura, and found a selective inhibition of high-threshold but not wide-dynamic range class of neurons.
