Ajovy (fremanezumab, Teva Pharmaceuticals, Israel) is a fully humanized monoclonal antibody that selectively binds both isoforms of the calcitonin gene-related peptide. Calcitonin gene-related peptide is a 37-amino acid neuropeptide involved in central and peripheral pathophysiological events in migraine. It is indicated for prophylaxis of migraine in adults who have at least four migraine days per month, and can be administered as a subcutaneous injection using an autoinjector device, with two dosing options: 225 mg once a month or 675 mg quarterly. In this article, I present data from Phase III clinical trials of fremanezumab in episodic and chronic migraine, in which fremanezumab demonstrated efficacy and had a favorable tolerability profile, with no serious treatment-related adverse events.

Fremanezumab is a humanized monoclonal antibody (IgG2Δa) that selectively targets calcitonin gene-related peptide and is approved in Europe for migraine prevention in adults with ≥4 migraine days/month. The Pan-European Real Life (PEARL) study is a 24-month, prospective, observational study of fremanezumab in chronic or episodic migraine. End points include proportion of patients with ≥50% reduction in monthly migraine days during 6 months of treatment (primary); changes in monthly migraine days, disability scores and acute headache medication use; adherence and persistence; and effectiveness in patients switching from another calcitonin gene-related peptide pathway-targeting monoclonal antibody. PEARL is being conducted in approximately 100 centers in 11 European countries (estimated n = 1100). PEARL will generate important real-world data on effectiveness of fremanezumab and treatment patterns in patients with chronic migraine or episodic migraine.

Our knowledge of the pathophysiology of migraine and the molecules implicated in the disorder have evolved over time. Among these, calcitonin gene-related peptide has shown a crucial role that led to the development of therapies specifically targeting the molecule. Four monoclonal antibodies targeting the calcitonin gene-related peptide pathway are currently available after the US FDA approval of eptinezumab for the indication of migraine prevention. This is the only one of the class to be administered intravenously. The pharmacology of eptinezumab and the four studies that led to the approval, two Phase II and two Phase III clinical trials, are reviewed in this paper. Eptinezumab has demonstrated efficacy, tolerability and safety in patients with episodic and chronic migraine. Studies including migraineurs who have failed previous preventives, and comparison with other options administered quarterly, as well as real-world experience data will all be welcome.

A significant proportion of patients exhibit sub-optimal response to the standard treatment of acute migraine such as triptans and NSAIDs. Even the conventional preventive therapies (e.g. beta-blockers) indicated for patients with frequent migraine attacks have varying responses. Moreover, evidence from animal studies elucidated the role of calcitonin gene-related peptide (CGRP) in the pathophysiology of migraine. Currently two classes are drug, the small molecule CGRP receptor antagonist or the ‘gepants’ (Ubrogepant, Rimegepant, Atogepant, Zavegepant) and CGRP monoclonal antibodies (Erenumab, Galcanezumab, Fremanezumab, Eptinezumab) have been found efficacious and safe in various clinical trials for the treatment and prevention of migraine. While the small molecule CGRP receptor antagonists are given orally, the monoclonal antibodies are injectable drugs. Ubrogepant and Rimegepant are the second-generation gepants approved for treatment of migraine. Zavegepant is a third generation gepant which has proven efficacy for acute treatment of migraine in a phase III trial. Atogepant has been approved for prevention of migraine. Rimegepant has also proven to be efficacious for preventing migraine attacks but has not yet been approved for this indication. Erenumab is the only monoclonal antibody which neutralizes the CGRP receptor. The latter three monoclonal antibodies target the CGRP peptide. The monoclonal antibodies have been approved for the prevention of migraine as a subcutaneously or intravenous infusion (Eptinezumab) given once a month or quarterly. Both the classes of drugs were well-tolerated in the clinical trials. Nausea was the most common adverse effect with gepants while injection-site pain was commonly reported with the antibodies.

This article seeks to analyze the clinical trials concerning the newly approved eptinezumab to assess its efficacy, safety, and application to current clinical practice. The Institute of Health US National Library of Medicine Clinical Trials, PubMed, and Cochrane Library databases were searched for relevant abstracts, journal articles, and other published sources. Search terms included eptinezumab, Vyepti®, and ALD403. Relevant English-language articles were evaluated and included in the narrative. Two randomized controlled trials compared quarterly infusions of eptinezumab 100 mg, eptinezumab 300 mg, and placebo in chronic and episodic migraine sufferers. In episodic migraine, eptinezumab resulted in a reduction of approximately 4 monthly migraine days, which was significant compared to placebo. In chronic migraine, eptinezumab reduced monthly migraine days by approximately 8 days, also significant compared to placebo. More patients who received eptinezumab experienced at least 75% reduction in monthly migraine days compared to placebo, resulting in a number needed to treat as low as 6, depending on the study population and the dose. The preventive impact was noticed day one post-infusion. The most common treatment-emergent adverse events were nausea and fatigue, and there was a low incidence of hypersensitivity or study withdrawal. Eptinezumab is the fourth Calcitonin Gene-related Peptide monoclonal antibody to receive Federal Drug Administration approval. Its delivery as a quarterly infusion sets it apart from the other agents in this class. As an infusion, eptinezumab has a quick onset of action that may prove especially beneficial to those with severe or refractory episodic or chronic migraines, despite the perceived increased direct and indirect cost of an infusion.

Background: The optimal monoclonal antibody against calcitonin gene-related peptide (CGRP) for adult patients with migraine has yet to be determined. Therefore, we aimed to compare the effectiveness of different monoclonal antibodies against CGRP or its receptor for adult patients with migraine through a network meta-analysis of randomized controlled trials.Methods: We systematically searched the MEDILNE, Embase, ClinicalTrials.gov, and Cochrane Library databases for relevant publications from inception until October 30, 2020. Only randomized clinical trials of adults with migraine that assessed any calcitonin gene-related peptide monoclonal antibody and reported clinical outcomes were included. The primary outcomes were changes in monthly migraine days and treatment-emergent adverse eventsResults: We initially retrieved 2,070 publications, and ultimately, 18 randomized clinical trials totaling 8,926 patients were included. In terms of efficacy, eptinezumab (MD −1.43, 95% CrI −2.59 to −0.36), erenumab (MD −1.61, 95% CrI −2.40 to −0.84), fremanezumab (MD −2.19, 95% CrI −3.15 to −1.25), and galcanezumab (MD −2.10, 95% CrI −2.76 to −1.45) significantly reduced MMDs compared with placebo. In terms of safety, only galcanezumab increased the incidences of TEAEs (RR 1.11, 95% CrI 1.01–1.22) and serious adverse events (RR 2.95, 95% CrI 1.41–6.87) compared with placebo.Conclusion: Most drugs performed similarly and were superior to placebo in most of our analyses. Further head-to-head research on different types of CGRP monoclonal antibodies is necessary to validate the present findings.

Migraine is a common and disabling disorder affecting approximately 1.02 billion people worldwide. Calcitonin gene-related peptide (CGRP) has been identified as playing an important role in the pathophysiology of migraine and several migraine-specific therapies targeting the CGRP ligand or its receptor have been approved since 2018 for the acute and preventive treatment of migraine. This review focuses on the pharmacology, clinical efficacy and safety/tolerability of galcanezumab, an anti-CGRP monoclonal antibody approved for the prevention of migraine.

Favorable Safety

Management of migraine in adolescents poses a great challenge, as many of the approved pharmacological migraine preventive agents have age restrictions. Following favorable safety and efficacy reports of the new class agent calcitonin gene-related peptide (CGRP) monoclonal antibody for use in migraine prevention, there is growing interest in its application in pediatric migraine. We present here a case series detailing our experience of using erenumab, a CGRP monoclonal antibody, in six adolescent patients. Two patients had a reduction of at least 50% in the mean number of monthly migraine days, one patient reported subjective improvement, while three patients did not respond to the first dose of erenumab and discontinued treatment. One patient reported constipation associated with erenumab use. We speculate that CGRP monoclonal antibody could potentially be a viable option in adolescent patients with migraine. Further evidences that support efficacy and safety of erenumab in this group is needed.
