Abstract
Background Chronic migraine is a disabling condition, affecting 2-4% of adults globally. With the introduction of expensive calcitonin gene-related peptide monoclonal antibodies, it is timely to compare the clinical effectiveness and cost-effectiveness of preventive drugs for chronic migraine. Objective To assess the clinical effectiveness and cost-effectiveness of medications used for chronic migraine through systematic reviews and economic modelling. Eligibility criteria Randomised controlled trials of drug treatments for efficacy with > 100 participants with chronic migraine per arm; for adverse events > 100 participants with episodic or chronic migraine per arm. Previous economic analyses of preventive drugs for chronic migraine. Data sources Eight databases. Reviews methods Systematic reviews, network meta-analysis and economic modelling. Outcomes Monthly headache days, monthly migraine days, headache-related quality of life, cost-effectiveness. Results We found 51 individual articles, reporting 11 randomised controlled trials, testing 6 drugs (topiramate, Botox, eptinezumab, erenumab, fremanezumab, galcanezumab), versus placebo, on 7352 adults with chronic migraine. Calcitonin gene-related peptide monoclonal antibodies, Botox and topiramate reduced headache/migraine days by 2.0-2.5, just under two, or by less than 1.5 days per month, respectively. In the network meta-analysis, eptinezumab 300 mg and fremanezumab monthly ranked in first place in both monthly headache day and monthly migraine day analyses. The calcitonin gene-related peptide monoclonal antibodies were consistently the best choices for headache/migraine days and headache-related quality of life. Topiramate was very unlikely to be the best choice for headache/migraine days and headache-related quality of life when compared to calcitonin gene-related peptide monoclonal antibodies or Botox. We found no trials of the commonly used drugs, such as propranolol or amitriptyline, to include in the analysis. The adverse events review included 40 randomised controlled trials with 25,891 participants; 3 additional drugs, amitriptyline, atogepant and rimegepant, were included. There were very few serious adverse events - none of which were linked to the use of these medications. Adverse events were common. Most people using some calcitonin gene-related peptide monoclonal antibodies reported injection site issues; and people using topiramate or amitriptyline had nervous system or gastrointestinal issues. The cost-effectiveness review identified 16 studies evaluating chronic migraine medications in adults. The newer, injected drugs are more costly than the oral preventatives, but they were cost-effective. Our economic model showed that topiramate was the least costly option and had the fewest quality-adjusted life-year gains, whereas eptinezumab 300 mg was more costly but generated the most quality-adjusted life-year gains. The cost-effectiveness acceptability frontier showed that topiramate was the most cost-effective medication if the decision maker is willing to pay up to £50,000 per quality-adjusted life-year. Our consensus workshop brought together people with chronic migraine and headache experts. Consensus was reached on the top three recommendations for future research on medications to prevent chronic migraine: (1) calcitonin gene-related peptide monoclonal antibodies and Botox versus calcitonin gene-related peptide monoclonal antibodies, (2) candesartan versus placebo and (3) flunarizine versus placebo. Limitations Topiramate was the only oral drug for which we were able to include data. We did not find sufficient quality evidence to support the use of other oral drugs. Conclusions We did not find evidence that the calcitonin gene-related peptide monoclonal antibodies are more clinically and cost-effective when compared to topiramate or Botox. We identified directions for future research these drugs might take. Study registration This study is registered as PROSPERO CRD42021265990, CRD42021265993 and CRD42021265995.

Abstract
INTRODUCTION Erenumab-aooe is approved for the preventive treatment of migraine in adults. Recent publications have evaluated migraine medication use during the 6 months after starting erenumab, but longer-term follow-up data are limited. The objective of this study was to describe 12-month medication use and changes in healthcare resource utilization (HRU) and associated direct costs among patients initiating erenumab. METHODS We identified adult patients with an erenumab claim in the Merative MarketScan Commercial and Medicare Databases from May 2018 through September 2019. Eligible patients had ≥ 12 months of continuous medical and pharmacy coverage before (pre-index period) and after (post-index period) the index date (first erenumab claim) in addition to pre-index evidence of migraine. Patients were stratified by post-index-period adherence to erenumab, defined as ≥ 80% of days covered (adherent) or < 80% of days covered (non-adherent). Outcomes were measured pre- and post-index, and differences between these periods were described. RESULTS Among 7528 eligible patients, the mean (standard deviation) age was 45.1 (11.4) years and 85.4% were female; 38.5% of patients were adherent to erenumab. Most patients used acute or traditional migraine-preventive medications pre-index, with reductions in use observed post-index (acute medication was used by 95.6% of patients pre-index, compared to 92.3% post-index; traditional preventive medication was used by 89.6% of patients pre-index, compared to 81.9% post-index). Reductions were observed for HRU of emergency room visits (- 3.8%) and brain- and other head-imaging studies (- 7.5%). Overall costs associated with acute and traditional preventive medications were reduced (- $764), but costs for HRU increased slightly ($76). When stratifying by adherence and combining costs for acute and traditional preventive medications and HRU, adherent patients had cost decreases (- $1947), while non-adherent patients had cost increases ($101). CONCLUSION Most patients initiating erenumab had prior use of acute and traditional migraine-preventive therapies. The reduction in acute and traditional migraine-preventive medication use and HRU over the 12-month follow-up supports the long-term clinical benefits of erenumab in the real-world setting.

Abstract
Migraine is a disease with a high prevalence and incidence, in addition to being highly disabling, causing a great impact on the patient's quality of life at a personal, family and work level, but also social, given its high expense due to its direct (care) and indirect (presenteeism and work absenteeism) costs. The multiple and recent developments in its pathophysiological knowledge and in its therapy require updating and, therefore, in this article the Spanish scientific societies most involved in its study and treatment (SEN, SEMFYC and SEMERGEN), together with the Association Spanish Association for Patients with Migraine and other Headaches (AEMICE), we have developed these updated care recommendations. We reviewed the treatment of migraine attacks, which consisted mainly of the use of NSAIDs and triptans, to which ditans and gepants have been added. We also discuss preventive treatment consisting of oral preventive drugs, botulinum toxin, and treatments that block the action of calcitonin-related peptide (CGRP). Finally, we emphasize that pharmacological treatments must be complementary to carrying out general measures consisting of identifying and managing/deletion the precipitating factors of the attacks and the chronicizing factors, controlling the comorbidities of migraine and eliminating analgesic overuse.

Abstract
Brain insulin resistance has recently been described as a metabolic abnormality of brain glucose homeostasis that has been proven to downregulate insulin receptors, both in astrocytes and neurons, triggering a reduction in glucose uptake and glycogen synthesis. This condition may generate a mismatch between brain's energy reserve and expenditure, mainly during high metabolic demand, which could be involved in the chronification of migraine and, in the long run, at least in certain subsets of patients, in the prodromic phase of Alzheimer's disease, along a putative metabolic physiopathological continuum. Indeed, the persistent disruption of glucose homeostasis and energy supply to neurons may eventually impair protein folding, an energy-requiring process, promoting pathological changes in Alzheimer's disease, such as amyloid-β deposition and tau hyperphosphorylation. Hopefully, the "neuroenergetic hypothesis" presented herein will provide further insight on there being a conceivable metabolic bridge between chronic migraine and Alzheimer's disease, elucidating novel potential targets for the prophylactic treatment of both diseases.

Abstract
Background Migraine is the second most common prevalent disorder worldwide and is a top cause of disability with a substantial economic burden. Many preventive migraine medications have notable side effects that affect different body organs. Method We systematically searched for published randomised controlled trials (RCTs) using terms for migraine/headache and preventive medications. Using eligibility criteria, two reviewers independently assessed the articles. Cochrane risk-of-bias tool was applied to assess the quality of the studies. Data were classified by system organ class (SOC). Results Thirty-two RCTs with 21 780 participants met the eligibility criteria for the incidence of adverse events (AEs). Additionally, 33 RCTs with 22 615 participants were included to synthesise the incidence of serious AEs (SAEs). The percentage of attributed AEs and SAEs to each SOC for 10 preventive drugs with different dosing regimens was calculated. Amitriptyline and topiramate had a higher incidence of nervous system disorders; Topiramate was also associated with a higher incidence of psychiatric disorders. All drugs showed a certain incidence of infections and infestations, with Onabotulinumtoxin A (BTA) having the lowest rate. BTA had a higher incidence of musculoskeletal disorders than the other drugs. Calcitonin gene-related peptide (CGRP) monoclonal antibodies (MAbs) such as fremanezumab and galcanezumab were linked to more general disorders and administration site conditions than other drugs. Conclusion Notably, the observed harm to SOCs varies among these preventive drugs. We suggest conducting head-to-head RCTs to evaluate the safety profile of oral medications, BTA, and CGRP MAbs in episodic and/or chronic migraine populations.

Abstract
Objectives: Migraine is a neurological disease with a high frequency of incidence. The new monoclonal antibodies selective for the calcitonin gene-related peptide and its ligand (anti-CGRP mAbs) have been marketed both in the USA and EU based on the positive efficacy results in the prevention of migraine. This search has been carried out with the aim of collecting real-world evidence on the effectiveness of anti-CGRP mAbs, performing a cost-savings analysis, and comparing performances among anti-CGRP mAbs medicines marketed in the American and European market. Methods: The literature review has been performed in PubMed database on 31 December 2022; the cost of the unitary dose of anti-CGRP mAbs has been extracted consulting an American national database. Results: The results confirm efficacy and good tolerability of anti-CGRP mAbs, determining a difference in the purchase price. In fact, all extracted studies showed a protective risk factor exposure in monthly migraine days reduction for all the anti-CGRP mAbs, whereas the cost analysis showed that using eptinezumab, in a quarter there is a cost saving of at least $425 per patient, compared with the other anti-CGRP mAbs. Conclusions: With equal efficacy and equal safety, anti-CGRP mAbs should be prescribed also regard to the cost established at the negotiation, making sure to guarantee the best treatment to the patients, but at the same time impacting as little as possible to the healthcare services resources.

Abstract
OBJECTIVE To evaluate response to anti-calcitonin gene-related peptide (CGRP) migraine preventives in a real-world community cohort of persons living with migraine and to identify clinical and genetic characteristics associated with efficacious response. BACKGROUND Erenumab-aooeb, fremanezumab-vrfm, and galcanezumab-gnlm target CGRP or its receptor; however, many patients are non-responsive. METHODS In this retrospective clinical and genetic study, we identified 1077 adult patients who satisfied the International Classification of Headache Disorders, 3rd edition, criteria for migraine without aura, migraine with aura, or chronic migraine and who were prescribed an anti-CGRP migraine preventive between May 2018 and May 2021. Screening of 558 patients identified 289 with data at baseline and first follow-up visits; data were available for 161 patients at a second follow-up visit. The primary outcome was migraine days per month (MDM). In 198 genotyped patients, we evaluated associations between responders (i.e., patients with ≥50% reduction in MDM at follow-up) and genes involved in CGRP signaling or pharmacological response, and genetic and polygenic risk scores. RESULTS The median time to first follow-up was 4.4 (0.9-22) months after preventive start. At the second follow-up, 5.7 (0.9-13) months later, 145 patients had continued on the same preventive. Preventives had strong, persistent effects in reducing MDM in responders (follow-up 1: η2 = 0.26, follow-up 2: η2 = 0.22). At the first but not second follow-up: galcanezumab had a larger effect than erenumab, while no difference was seen at either follow-up between galcanezumab and fremanezumab or fremanezumab and erenumab. The decrease in MDM at follow-up was generally proportional to baseline MDM, larger in females, and increased with months on medication. At the first follow-up only, patients with prior hospitalization for migraine or who had not responded to more preventive regimens had a smaller decrease in MDM. Reasons for stopping or switching a preventive varied between medications and were often related to cost and insurance coverage. At both follow-ups, patient tolerance (1: 92.2% [262/284]; 2: 95.2% [141/145]) and continued use (1: 77.5% [224/289]; 2: 80.6% [116/145]) were high and similar across preventives. Response consistency (always non-responders: 31.7% [46/145]; always responders: 56.5% [82/145], and one-time only responders: 11.7% [17/145]) was also similar across preventives. Non-responder status had nominally significant associations with rs12615320-G in RAMP1 (odds ratio [95% confidence interval]: 4.7 [1.5, 14.7]), and rs4680-A in COMT (0.6[0.4, 0.9]). Non-responders had a lower mean genetic risk score than responders (1.0 vs. 1.1; t(df) = -1.75(174.84), p = 0.041), and the fraction of responders increased with genetic and polygenic risk score percentile. CONCLUSIONS In this real-world setting, anti-CGRP preventives reduced MDM persistently and had similar and large effect sizes on MDM reduction; however, clinical and genetic factors influenced response.

Abstract
BACKGROUND Chronic migraine can be a profoundly disabling disorder that may be treated with preventive medications. However, uncertainty remains as to which preventive medication is the most effective. We present a network meta-analysis to determine the effectiveness and rank of preventive drugs for chronic migraine in adults. METHODS We identified, reviewed, and extracted data from randomised controlled trials (RCTs) of preventive drugs for chronic migraine with at least 200 participants. Data were analysed using network meta-analysis. FINDINGS We included 12 RCTs of six medications (Eptinezumab, Erenumab, Fremanezumab, Galcanezumab, Onabotulinumtoxin A, and Topiramate) compared to placebo or each other. All drugs effectively reduced monthly headache and migraine days compared with placebo. The most effective drug for monthly headache days was Eptinezumab 300mg, with a mean difference of -2.46 days, 95% Credible Interval (CrI): -3.23 to -1.69. On the Surface Under the Cumulative Ranking Area (SUCRA) analysis, the probability that Eptinezumab 300mg was ranked highest was 0.82. For monthly migraine days, the most effective medication was Fremanezumab-monthly, with a mean difference: -2.77 days, 95% CrI: -3.36 to -2.17, and 0.98 probability of being ranked the highest. All included drugs, except Topiramate, improved headache-related quality of life. No eligible studies were identified for the other common preventive oral medications such as Amitriptyline, Candesartan, and Propranolol. The main reasons were that the studies did not define chronic migraine, were undertaken before the definition of chronic migraine, or were too small. INTERPRETATION All six medications were more effective than the placebo on monthly headache and migraine days. The absolute differences in the number of headache/migraine days are, at best, modest. No evidence was found to determine the relative effectiveness of the six included drugs with other oral preventive medications. REGISTRATION PROSPERO (number CRD42021265990).

[PMID: 37998384 PMCID: PMC10670698 DOI: 10.3390/cells12222649] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 11/13/2023] [Accepted: 11/14/2023] [Indexed: 11/25/2023] Open
Abstract
Migraine is a neurovascular disorder that can be debilitating for individuals and society. Current research focuses on finding effective analgesics and management strategies for migraines by targeting specific receptors and neuropeptides. Nonetheless, newly approved calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAbs) have a 50% responder rate ranging from 27 to 71.0%, whereas CGRP receptor inhibitors have a 50% responder rate ranging from 56 to 71%. To address the need for novel therapeutic targets, researchers are exploring the potential of another secretin family peptide, pituitary adenylate cyclase-activating polypeptide (PACAP), as a ground-breaking treatment avenue for migraine. Preclinical models have revealed how PACAP affects the trigeminal system, which is implicated in headache disorders. Clinical studies have demonstrated the significance of PACAP in migraine pathophysiology; however, a few clinical trials remain inconclusive: the pituitary adenylate cyclase-activating peptide 1 receptor mAb, AMG 301 showed no benefit for migraine prevention, while the PACAP ligand mAb, Lu AG09222 significantly reduced the number of monthly migraine days over placebo in a phase 2 clinical trial. Meanwhile, another secretin family peptide vasoactive intestinal peptide (VIP) is gaining interest as a potential new target. In light of recent advances in PACAP research, we emphasize the potential of PACAP as a promising target for migraine treatment, highlighting the significance of exploring PACAP as a member of the antimigraine armamentarium, especially for patients who do not respond to or contraindicated to anti-CGRP therapies. By updating our knowledge of PACAP and its unique contribution to migraine pathophysiology, we can pave the way for reinforcing PACAP and other secretin peptides, including VIP, as a novel treatment option for migraines.

Abstract
OBJECTIVE This study aimed to determine the number needed to treat (NNT), number needed to harm (NNH), and likelihood of being helped or harmed (LHH) in a post hoc analysis of the phase 3b FOCUS trial. BACKGROUND Fremanezumab, a humanized monoclonal antibody that selectively targets calcitonin gene-related peptide (CGRP), has demonstrated efficacy, tolerability, and safety in adults with episodic migraine (EM) or chronic migraine (CM), with documented previous inadequate response to two to four classes of migraine preventive medications. METHODS In the 12-week double-blind period of the FOCUS study, patients were randomized (1:1:1) to quarterly fremanezumab, monthly fremanezumab, or matched monthly placebo. NNT was based on responder analysis, defined as ≥50% reduction in monthly average number of migraine days at 12 weeks. NNH was based on discontinuations due to adverse events (AEs). RESULTS Among patients with CM (n = 509), response rates and discontinuation rates were 27% (45/169) and 0 for quarterly fremanezumab, 29% (50/173) and 2% (3/173) for monthly fremanezumab, and 8% (13/167) and <1% (1/167) for placebo, respectively. These results translated to NNTs of 5.3 and 4.7, NNHs of 1000 and 88, and LHHs of 188 and 19 for quarterly and monthly fremanezumab, respectively. Among patients with EM (n = 328), response rates were 47% (50/107) for quarterly fremanezumab, 43% (47/110) for monthly fremanezumab, and 10% (11/111) for placebo. Discontinuation rates were <1% (n = 1) in all three groups. These results translated to NNTs of 2.7 and 3.0, NNHs of 1000 and 1000, and LHHs of 368 and 328 for quarterly and monthly fremanezumab, respectively. CONCLUSIONS The NNT, NNH, and LHH for quarterly and monthly fremanezumab compare favorably with those for traditional oral preventive medications, including topiramate, valproate, and propranolol.

Abstract
OBJECTIVES Grading of Recommendations, Assessment Development and Evaluation (GRADE) tables were created using a standardized and independent assessment of the efficacy and side effects of treatments with monoclonal antibodies (mAb) against calcitonin gene-related peptide (CGRP) or the CGRP receptor for the prevention of migraine. We hope to provide support for author groups writing national or regional treatment or management guidelines for migraine prevention. METHODS We formulated patient/population, intervention, comparison and outcomes (PICO) questions for the efficacy and safety of mAb against CGRP or the CGRP-receptor for the prevention of migraine attacks. We performed a systematic literature research for randomized studies with eptinezumab, erenumab, fremanezumab and galcanezumab and a pooled analysis was done, using RevMan 5.4 software. For dichotomous outcomes we used risk ratio, and for continuous outcomes we used the mean difference to compare and summarize the evidence between groups. The evidence across studies, for each outcome, except serious adverse events, was assessed using GRADE evidence tables. Additionally, we report the serious adverse effects in the tables of the characteristics of the studies. RESULTS All mAb are superior to placebo for the reduction in monthly migraine days (days in which a headache consistent with migraine occurred) in participants with episodic and chronic migraine. There are no major differences between the mAb. CONCLUSIONS The GRADE evidence summary tables provided will support author groups to write treatment guidelines for the prevention of migraine with mAb.

Abstract
The neuropeptide calcitonin gene-related peptide (CGRP) is an essential pathophysiological treatment for migraines. A unique class of medications called CGRP monoclonal antibodies target CGRP and its receptor and have demonstrated promising benefits in the treatment and prevention of migraines. This study sought to identify and assess the quality of existing systematic reviews about the effectiveness of CGRP antibodies for preventing migraines, as well as systematically review and synthesize the evidence on these topics. This included the four Food and Drug Administration (FDA)-approved medications erenumab, galcanezumab, fremanezumab, and eptinezumab. The effectiveness and safety of these monoclonal antibodies in preventing migraines should also be examined in light of patient characteristics, and any gaps in the body of knowledge should be noted in order to suggest new lines of investigation. Data gathering included a thorough search of internet databases (PubMed, Cochrane Library, Web of Science, and Scopus) for relevant research released between 2018 and 2023. The findings imply that CGRP monoclonal antibodies are efficient and secure for preventing migraines and may be considered a first-line alternative for treating migraines and drug misuse. The results further imply that combination treatment with CGRP antibodies and onabotulinumtoxinA may enhance the prevention of migraine in adults. With suggestions for more studies to find and address these variables, the significance of genetic and epigenetic factors in the progression of pediatric patients' acute postoperative pain to chronic postsurgical pain is underlined. All four anti-CGRP monoclonal antibodies, erenumab, fremanezumab, galcanezumab, and eptinezumab, were shown to be safe and effective for the prevention of migraine when the research additionally looked at their individual effectiveness and safety. Additionally, the study discovered considerable variances in effectiveness amongst various groups. However, further investigation is required to establish the best time and dosage and the effect of patient characteristics on the effectiveness and safety of these medications.

Abstract
Background. Monoclonal antibodies (mAbs) directed against the calcitonin gene-related peptide (CGRP) or its receptor represented the first targeted and specialized approach to migraine prophylaxis. Nevertheless, they have been rarely considered in the treatment of vestibular migraine (VM). Our aim was to evaluate the effectiveness of anti-CGRP mAbs in VM patients who did not respond to conventional migraine treatments. Methods. Consecutive VM patients treated with erenumab were considered. As a comparison, we considered the same VM patients during conventional migraine treatments (i.e., propranolol, flunarizine, or valproic acid), which were tried before mAbs therapy. Videonystagmography, the Italian version of the Dizziness Handicap Inventory (DHI) questionnaire, and migraine days over the last 3 months were evaluated in all patients before and after treatments. Results. In the present retrospective study, we included 21 female and 2 male VM patients, mean age 45.2 years. All patients underwent contrast-enhanced magnetic resonance imaging that ruled out other causes of vertigo. The DHI questionnaire significantly improved after mAb therapy (p < 0.0001). Mean migraine days over the last 3 months were significantly reduced after treatment (p = 0.001). Videonystagmography was altered in 11 (48%) patients prior to monoclonal antibodies. We found vertical positional nystagmus in 9 patients and horizontal positional nystagmus in 2 patients. After the treatment, we found vertical positional nystagmus only in 1 patient (p = 0.002). When patients were treated with conventional therapies, there was no significant reduction in DHI, and instrumental vestibular examinations remained altered. Conclusions. VM patients using anti-CGRP mAbs experienced a reduction in the dizziness-derived handicap, as reported in the DHI questionnaire. Furthermore, these treatments were significantly associated with a normalization of vestibular instrumental analysis. These findings were not seen with conventional treatments. Treatment with anti-CGRP mAbs may be effective in VM patients who did not respond to conventional migraine treatments. These findings should be tested in large, randomized clinical trials.

Abstract
The monoclonal antibodies (mAbs) blocking the calcitonin-gene related peptide (CGRP) pathway, collectively called here "anti-CGRP/rec mAbs", have dramatically improved preventive migraine treatment. Although their efficacy and tolerability were proven in a number of randomized controlled trials (RCTs) and, maybe even more convincingly, in real world settings, a number of open questions remain. In this narrative review, we will analyze published data allowing insight in some of the uncertainties related to the use of anti-CGRP/rec mAbs in clinical practice: their differential efficacy in migraine subtypes, outcome predictors, switching between molecules, use in children and adolescents, long-term treatment adherence and persistence, effect persistence after discontinuation, combined treatment with botulinum toxin or gepants, added-value and cost effectiveness, effectiveness in other headache types, and potential contraindications based on known physiological effects of CGRP. While recent studies have already provided hints for some of these questions, many of them will not find reliable and definitive answers before larger studies, registries or dedicated RCTs are available.

Abstract
Among numerous approaches to the study of migraine, the nitroglycerin (NTG) model occupies a prominent place, but there is relatively insufficient information about how NTG affects intracranial vessels. In this study we aim to assess the effects of NTG on blood-flow parameters in meningeal vessels measured by imaging photoplethysmography (iPPG) in animal experiments. An amplitude of the pulsatile component (APC) of iPPG waveform was assessed before and within 2.5 h after the NTG administration in saline (n = 13) or sumatriptan (n = 12) pretreatment anesthetized rats in conditions of a closed cranial window. In animals of both groups, NTG caused a steady decrease in blood pressure. In 7 rats of the saline group, NTG resulted in progressive increase in APC, whereas decrease in APC was observed in other 6 rats. In all animals in the sumatriptan group, NTG administration was accompanied exclusively by an increase in APC. Diametrically opposite changes in APC due to NTG indicate a dual effect of this drug on meningeal vasomotor activity. Sumatriptan acts as a synergist of the NTG vasodilating action. The results we obtained contribute to understanding the interaction of vasoactive drugs in the study of the headache pathophysiology and methods of its therapy.

Effects of Fremanezumab on Psychiatric Comorbidities in Difficult-to-Treat Patients with Chronic Migraine: Post Hoc Analysis of a Prospective, Multicenter, Real-World Greek Registry. J Clin Med 2023; 12:4526. [PMID: 37445560 DOI: 10.3390/jcm12134526] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Revised: 07/03/2023] [Accepted: 07/04/2023] [Indexed: 07/15/2023] Open
Abstract
OBJECTIVE this post hoc analysis aimed to evaluate the efficacy of fremanezumab in difficult-to-treat chronic migraine (CM) patients with and without psychiatric comorbidities (PCs), mainly anxiety and/or depression. METHODS We assessed data from CM patients with and without PCs who failed at least 3 preventives and eventually received at least 3 consecutive monthly doses of fremanezumab 225 mg. Outcomes included the crude response (≥50% reduction in monthly headache days (MHDs)) rates to fremanezumab from the baseline to the last clinical follow-up. The changes in MHDs; MHDs of moderate/greater severity; monthly days with intake of abortive medication; and the proportion of patients' changing status from with PCs to decreased/without PCs were also compared. Disability and quality of life (QOL) outcomes were also assessed. RESULTS Of 107 patients enrolled, 65 (60.7%) had baseline PCs. The percentage of patients with (n = 38/65; 58.5%) and without (n = 28/42; 66.6%) PCs that achieved a ≥50% reduction in MHDs with fremanezumab was comparable (p = 0.41), whereas MHDs were significantly reduced (difference vs. baseline) in both patients with PCs (mean -8.9 (standard error: 6.8); p < 0.001) and without PCs (-9.8 (7.5); p < 0.001). Both groups experienced significant improvements in all other efficacy, disability, and QOL outcomes at comparable rates, including in MHD reduction. A significant proportion of fremanezumab-treated patients with baseline PCs de-escalated in corresponding severities or even reverted to no PCs (28/65; 43.1%) post-fremanezumab. CONCLUSIONS fremanezumab appears to be effective as a preventive treatment in difficult-to-treat CM patients with and without PCs while also being beneficial in reducing the severity of comorbid anxiety and/or depression.

Future targets for migraine treatment beyond CGRP. J Headache Pain 2023; 24:76. [PMID: 37370051 DOI: 10.1186/s10194-023-01567-4] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Accepted: 03/14/2023] [Indexed: 06/29/2023] Open
Abstract
BACKGROUND Migraine is a disabling and chronic neurovascular headache disorder. Trigeminal vascular activation and release of calcitonin gene-related peptide (CGRP) play a pivotal role in the pathogenesis of migraine. This knowledge has led to the development of CGRP(-receptor) therapies. Yet, a substantial proportion of patients do not respond to these treatments. Therefore, alternative targets for future therapies are warranted. The current narrative review provides a comprehensive overview of the pathophysiological role of these possible non-CGRP targets in migraine. FINDINGS We covered targets of the metabotropic receptors (pituitary adenylate cyclase-activating polypeptide (PACAP), vasoactive intestinal peptide (VIP), amylin, and adrenomedullin), intracellular targets (nitric oxide (NO), phosphodiesterase-3 (PDE3) and -5 (PDE5)), and ion channels (potassium, calcium, transient receptor potential (TRP), and acid-sensing ion channels (ASIC)). The majority of non-CGRP targets were able to induce migraine-like attacks, except for (i) calcium channels, as it is not yet possible to directly target channels to elucidate their precise involvement in migraine; (ii) TRP channels, activation of which can induce non-migraine headache; and (iii) ASICs, as their potential in inducing migraine attacks has not been investigated thus far. Drugs that target its receptors exist for PACAP, NO, and the potassium, TRP, and ASIC channels. No selective drugs exist for the other targets, however, some existing (migraine) treatments appear to indirectly antagonize responses to amylin, adrenomedullin, and calcium channels. Drugs against PACAP, NO, potassium channels, TRP channels, and only a PAC1 antibody have been tested for migraine treatment, albeit with ambiguous results. CONCLUSION While current research on these non-CGRP drug targets has not yet led to the development of efficacious therapies, human provocation studies using these targets have provided valuable insight into underlying mechanisms of migraine headaches and auras. Further studies are needed on these alternative therapies in non-responders of CGRP(-receptor) targeted therapies with the ultimate aim to pave the way towards a headache-free future for all migraine patients.

Saccà F, Braca S, Sansone M, Miele A, Stornaiuolo A, De Simone R, Russo CV. A head-to-head observational cohort study on the efficacy and safety of monoclonal antibodies against calcitonin gene-related peptide for chronic and episodic migraine. Headache 2023; 63:788-794. [PMID: 37254581 DOI: 10.1111/head.14528] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Revised: 04/09/2023] [Accepted: 04/10/2023] [Indexed: 06/01/2023]
Abstract
OBJECTIVE To compare the effectiveness and safety of galcanezumab, fremanezumab, and erenumab for the treatment of chronic and episodic migraine, through real-world data. BACKGROUND Monoclonal antibodies (mAbs) targeting the calcitonin gene-related peptide (CGRP) pathway have been tested extensively in several clinical trials for both episodic and chronic migraine, showing high effectiveness, safety, and tolerability; however, there are no prospective real-world studies intending to compare their efficacy and safety. METHODS This is a prospective observational cohort study comparing the effectiveness and safety profiles of galcanezumab, fremanezumab, and erenumab for the treatment of chronic and episodic migraine. We enrolled 140 patients at the Headache Centre of University Federico II of Naples, with a history of multiple failed treatments with validated migraine preventatives. Framenezumab, erenumab, or galcanezumab were administered for 12 months. The mean monthly days with headache, Migraine Disability Assessment (MIDAS) score, and adverse events were evaluated during the run-in period and every 3 months by reviewing standardized paper patient headache diaries. RESULTS We found a mean reduction of migraine monthly days from baseline of -12.0 (-9.8, -14.1) in the galcanezumab group, -12.3 (-10.2, -14.3) in the fremanezumab group, and -10.8 (-8.5, -13.1) in the erenumab group (for all, p < 0.001). We found a mean reduction of MIDAS score of -32.6 (-26.6, -38.5) in the galcanezumab group, -33.4 (-28.0, -38.9) in the fremanezumab group, and -29.2 (-23.0, -35.4) in the erenumab group (for all, p < 0.001). We found no significant differences between mAbs in the reduction of mean monthly days with headache and MIDAS score. We found a more rapid effect of galcanezumab and erenumab compared to fremanezumab in medication overuse headache patients after 3 months of treatment (-10.8 and -11.1 vs. -4.0 days; p = 0.029). CONCLUSION Our results confirm the therapeutic benefits of anti-CGRP mAbs. There is no evidence that suggests that one antibody may be superior to the others in terms of effectiveness, both in chronic and episodic patients.

Predictors of Response to Fremanezumab in Migraine Patients with at Least Three Previous Preventive Failures: Post Hoc Analysis of a Prospective, Multicenter, Real-World Greek Registry. J Clin Med 2023; 12:jcm12093218. [PMID: 37176658 PMCID: PMC10179256 DOI: 10.3390/jcm12093218] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 04/24/2023] [Accepted: 04/28/2023] [Indexed: 05/15/2023] Open
Abstract
OBJECTIVE To define, in a real-world population of patients with high-frequency episodic (HFEM) or chronic migraine (CM), the predictive role of socio-demographic or phenotypic profiling of responders to fremanezumab. PATIENTS AND METHODS Two-hundred and four adult fremanezumab-treated patients with either HFEM or CM, who failed to at least three preventive treatments, provided data at baseline on several individual socio-demographic and phenotypic variables. These variables were analyzed for their ability to independently predict the response (50-74% response rates) or super-response (≥ 75% response rates) to fremanezumab. Patients were followed from 3-18 months of fremanezumab exposure. RESULTS The main finding to emerge from univariate analyses was that three baseline socio-demographic/clinical variables, i.e., age group 41-70 years (p = 0.02); female gender (p = 0.03); patients with HFEM (p = 0.001), and three clinical phenotypic variables, i.e., strict unilateral pain (p = 0.05); pain in the ophthalmic trigeminal branch (p = 0.04); and the "imploding" quality of pain (p = 0.05), were significantly related to fremanezumab response. However, in multivariate analysis, only HFEM (p = 0.02), the presence of strict unilateral (p = 0.03), and pain location in the ophthalmic trigeminal branch (p = 0.036) were independently associated with good fremanezumab response. Allodynia (p = 0.04) was the only clinical predictive variable of super-responsiveness to fremanezumab. CONCLUSIONS A precise phenotypic profiling with identification of pain characteristics consistent with peripheral and/or central sensitization might reliably predict the responsiveness to fremanezumab in migraine prophylaxis.

Abstract
BACKGROUND Several novel treatments targeting the calcitonin gene-related peptide pathway have been developed for migraine. We evaluated the efficacy of these medications, including atogepant, rimegepant, erenumab, eptinezumab, fremanezumab, and galcanezumab, for the prevention of migraine via network meta-analysis. METHODS Databases, including MEDLINE via PubMed, EMBASE, and Cochrane central, were systematically reviewed, and all eligible phase 3 randomised controlled trials were included. RESULTS Nineteen studies (n = 14,584 participants) were included. Studies included episodic (n = 11) and chronic (n = 4) migraine or both (n = 4). All interventions, except for eptinzumab 30 mg, significantly reduced mean monthly migraine days compared to placebo. All medications had a higher ≥50% responder rate than placebo and results were statistically significant in those with the subcutaneous or intravenous route of administrations, but not with the oral one. All medications significantly reduced mean monthly headache days, although no data for this outcome was available for rimegepant, and mean monthly acute medication days, with no data for eptinezumab. CONCLUSION The results show that medications targeting calcitonin gene-related peptide were effective in preventing migraine compared to placebo. Considering limitations of single studies, different populations such as episodic and chronic migraine, and the absence of head-to-head trials, all novel treatments decreased mean monthly migraine and headache days, and showed higher 50%, 75% and 100% responder rates than placebo.Trial registration: PROSPERO registration: CRD42022310579.

Abstract
BACKGROUND Direct comparisons of the tolerability and safety of migraine preventive treatments targeting the calcitonin gene-related peptide pathway are lacking. This study aimed to compare the safety and tolerability of anti-calcitonin gene-related peptide monoclonal antibodies and gepants in migraine prevention. METHODS A network meta-analysis of phase 3 randomized controlled trials assessing the safety and tolerability of anti-calcitonin gene-related peptide monoclonal antibodies (erenumab, eptinezumab, fremanezumab, or galcanezumab) and gepants (atogepant, rimegepant) in migraine prevention was performed. Primary outcomes were treatment-emergent adverse events and serious adverse events. Secondary outcomes included any adverse events, adverse events leading to treatment discontinuation and individual adverse events. RESULTS We included 19 randomized controlled trials, comprising 14,584 patients. Atogepant 120 mg (OR 2.22, 95% CI [1.26, 3.91]) and galcanezumab 240 mg (OR 1.63, 95% CI [1.33, 2.00]) showed the largest odds of treatment-emergent adverse events compared to placebo. While eptinezumab 30 mg had greater odds of adverse events leading to treatment discontinuation (OR 2.62, 95% CI [1.03,6.66]). No significant differences in serious adverse events were found between active treatments and placebo. Eptinezumab was associated with the lowest odds of treatment-emergent adverse events and serious adverse events compared to placebo, whereas erenumab was associated with the lowest odds of any adverse events and quarterly fremanezumab with the lowest odds of treatment discontinuation due to adverse events. CONCLUSION Monoclonal antibodies targeting the calcitonin gene-related peptide pathway and gepants are a safe and well tolerated option for migraine prevention.

Abstract
BACKGROUND AND PURPOSE Based on their pharmacological target, two classes of calcitonin-gene-related peptide (CGRP) monoclonal antibodies (mAbs) have been identified: antibodies against the CGRP ligand-galcanezumab, fremanezumab, eptinezumab-and antibodies against the CGRP receptor (CGRP-R), erenumab. The aim of the present study was to compare anti-CGRP versus anti-CGRP-R mAbs in patients with high frequency episodic and chronic migraine. METHODS All patients on monthly treatment with anti-CGRP mAbs with an available 6 months' follow-up at January 2022 were included. Data on efficacy outcome were collected following one (T1), three (T3) and six (T6) months of treatment, and included monthly headache/migraine days, the Migraine Disability Assessment Scale (MIDAS) and Headache Impact Test 6 (HIT-6) scores, pain intensity, analgesics consumption and response rates (>50% headache days reduction compared to baseline). RESULTS In all, 152 patients were enrolled, of whom 68 were in treatment with anti-CGRP mAbs (49 galcanezumab, 19 fremanezumab) and 84 with the anti-CGRP-R (erenumab). MIDAS scores were significantly lower in the anti-CGRP group at T1 and T3 (respectively p < 0.02 and p < 0.03) as well as the number of mean migraine days at T3 (p < 0.01). At T3 and T6 outcome measures were comparable, although a significantly higher percentage of super-responders was found in the anti-CGRP group (respectively p < 0.04 and p < 0.05), with a similar overall percentage of responders. CONCLUSIONS The present study on a real-world sample confirms the beneficial effect of both anti-CGRP and anti-CGRP-R mAbs, with a more favorable outcome for anti-CGRP antibodies.

Abstract
BACKGROUND AND OBJECTIVE Several studies on use of erenumab for migraine treatment have been published over recent years. However, its long-term safety and effectiveness have not been consistently established in the literature yet. We aimed to perform a qualitative and quantitative analysis of the long-term safety and effectiveness of erenumab for the treatment of migraine headaches. METHODS Long-term follow-up was defined as ≥ 1 year. PubMed, Embase and Cochrane Library were systematically searched from inception to 14 June 2022 for studies meeting the inclusion criteria. Risk of bias was assessed using the Newcastle-Ottawa Scale. RESULTS Fourteen studies, comprising 3574 patients, were included. The total follow-up period ranged from 48 to 268 weeks (i.e., 1 year to 5.6 years). Pooled estimate rates for all adverse events (AEs) were 63% (95% CI 46-78); for serious AEs, 3% (95% CI 1-7); and for AEs leading to discontinuation of erenumab, 3% (95% CI 2-5). Reduction in monthly migraine days (MMDs) was -6.98 (95% CI -8.90 to -5.05) and in migraine-specific medication days (MSMDs) was - 6.09 (95% CI - 9.43 to - 2.75). More than half (57%; 95% CI 51-63) and around one-third (35%; 95% CI 28-42) of patients presented with reductions of ≥ 50% and ≥ 75% in MMDs, respectively. Headache Impact Test-6 (HIT-6) score was decreased by -9.68 points (95% CI - 12.03 to - 7.34). Nine studies were considered of poor methodological quality and five of fair quality. CONCLUSIONS Erenumab has a favorable safety profile, with a low incidence of serious AEs, and sustained efficacy over ≥1 year of follow-up in the treatment of migraine.

Abstract
Background and objectives The identification of predictors of response to antiCGRP mAbs could favor tailored therapies and personalized treatment plans. This study is aimed at investigating predictors of ≥ 50%, ≥ 75% and 100% response at 24 weeks in patients with high-frequency episodic (HFEM: 8–14 days/month) or chronic migraine (CM). Methods This is a large, multicenter, cohort, real-life study. We considered all consecutive adult patients affected by HFEM or CM who were prescribed antiCGRP mAbs for ≥ 24 weeks in 20 headache centers. Patients were interviewed face-to-face using a shared semi-structured questionnaire carefully exploring socio-demographic and clinical characteristics. Patients received subcutaneous erenumab (70 mg or140 mg, monthly), galcanezumab (120 mg monthly, following a 240 mg loading dose), or fremanezumab (225 mg, monthly or 675 mg, quarterly) according to drug market availability, physician’s choice, or patient’s preference. The primary endpoint of the study was the assessment of ≥ 50% response predictors at 24 weeks. Secondary endpoints included ≥ 75% and 100% response predictors at 24 weeks. Results Eight hundred sixty-four migraine patients had been treated with antiCGRP mAbs for ≥ 24 weeks (erenumab: 639 pts; galcanezumab: 173 pts; fremanezumab: 55 pts). The ≥50% response (primary endpoint) in HFEM was positively associated with unilateral pain (UP) + unilateral cranial autonomic symptoms (UAs) (OR:4.23, 95%CI:1.57–11.4; p = 0.004), while in CM was positively associated with UAs (OR:1.49, 95%CI:1.05–2.11; p = 0.026), UP + UAs (OR:1.90, 95%CI:1.15–3.16; p = 0.012), UP + allodynia (OR:1.71, 95%CI:1.04–2.83; p = 0.034), and negatively associated with obesity (OR:0.21, 95%CI:0.07–0.64; p = 0.006). The 75% response (secondary endpoint) was positively associated with UP + UAs in HFEM (OR:3.44, 95%CI:1.42–8.31; p = 0.006) and with UP + UAs (OR:1.78, 95%CI:1.14–2.80; p = 0.012) and UP + allodynia (OR:1.92, 95%CI:1.22–3.06; p = 0.005) in CM. No predictor of 100% response emerged in patients with HFEM or CM. Conclusions A critical evaluation of headache characteristics indicating peripheral or central sensitization may help in predicting responsiveness to antiCGRP mAbs in HFEM and CM. A more precise pain profiling may represent a steppingstone for a mechanism-based approach and personalized treatment of migraine with compounds targeting specific molecular mechanisms.

Abstract
Migraine is a highly prevalent neurovascular disorder afflicting more than 15% of the global population. Nearly three times more females are afflicted by migraine in the 18-50 years age group, compared to males. Migraine attacks are most often sporadic, but a subgroup of individuals experience a gradual increase in frequency over time; among these, up to 1%-2% of the global population develop chronic migraine. Although migraine symptoms have been known for centuries, the underlying mechanisms remain largely unknown. Two theories have dominated the current thinking-a neurovascular theory and a central neuronal theory with the origin of the attacks in the hypothalamus. During the last decades, the understanding of migraine has markedly advanced. This is supported by the early seminal demonstration of the trigeminovascular reflex 35 years ago and the insight that calcitonin gene-related peptide (CGRP) is a key molecule released in acute migraine attacks. The more recent findings that gepants, small molecule CGRP receptor blockers, and monoclonal antibodies generated against CGRP, or its canonical receptor are useful for the treatment of migraine, are other important issues. CGRP has been established as a key molecule in the neurobiology of migraine. Moreover, monoclonal antibodies to CGRP or the CGRP receptor represent a breakthrough in the understanding of migraine pathophysiology and have emerged as an efficacious prophylactic treatment for patients with severe migraine with excellent tolerability. This review describes the progression of research to reach the clinical usefulness of a large group of molecules that have in common the interaction with CGRP mechanisms in the trigeminal system to alleviate the burden for individuals afflicted by migraine.

Abstract
In light of the multiple pharmacologic alternatives for migraine management, the adverse effects associated with different treatment regimens, and their varying efficacy, it is vital to undertake ongoing evaluations and seek a tailored therapeutic strategy. This case report describes two patients who presented with classic migraine headaches, with the first responding to both abortive and prophylactic migraine medications and the second, with status migrainosus-like presentation, responding to the newer antimigraine agents. We also examined current pharmacological therapeutic options and existing recommendations, analyzing their strengths and weaknesses. This case review exemplifies how treatment in the last 10 years and success in medications used for abortive and prophylactic therapy are evolving from the older agents to newer agents like the recently approved calcitonin gene receptor protein monoclonal antibody inhibitors.

Abstract
The standard of care paradigm for migraine treatment has been based almost exclusively on approaches that grew out of the happenstance use of market pharmaceuticals. Only methysergide, which has long since been removed from use for safety concerns, the ergotamine family of drugs, and the triptans were explicitly developed with migraine and other vascular headaches in mind. While the forward and innovative thinking to utilize the broad array of agents to treat migraine served millions well, their therapeutic efficacy was often low, and adverse event profiles were troublesome in the least. Advances in biochemical and molecular biology and the application of advanced "designing drugs" methods have brought about a potentially significant shift in treatment. The gepants have efficacies similar to the triptans but without vascular safety or medication overuse concerns. Preventative gepants offer innovative approaches to prevention and efficacy that exceed even the CGRP monoclonal antibodies. Those monoclonal antibodies brought rapid and highly effective outcomes across the spectrum of migraine. They outpaced older oral medication efficacy and eliminated most adverse events while potentially improving compliance with monthly or quarterly dosing. Other serotonin receptors beyond the 5HT1B and1D receptors have been targeted for decades. They now lead us to better formulations of dihydroergotamine for efficacy, convenience, and tolerability, and a 5HT1F-specific acute treatment like the gepants opens new options for acute management. Neuromodulation goes back to the mid-1800's. Our improved understanding of applied biomedical engineering has brought forward several tantalizing devices, including the application of currents distant from the target and patient regulated. Whether these advances change the paradigm of migraine treatment and standards of care remains to be seen, and issues such as cost and patient acceptance will help mold it.

Abstract
Migraine is a neurological disorder that affects millions of children and adolescents worldwide. Chronic migraine is a subtype of migraine in which patients experience headaches for more days than not each month, with accompanying symptoms of phonophobia, photophobia, nausea or vomiting for most of these headaches. The burden and impact of chronic migraine in the daily lives of children and adolescents is substantial, requiring a holistic, multidisciplinary, and biopsychosocial approach to conceptualization and treatment. The purpose of this review is to provide a comprehensive “2022” overview of acute and preventive treatments for the management of chronic migraine in youth. We first describe diagnostic criteria for chronic migraine and highlight the state of evidence for acute and preventive treatment in children and adolescents. We then discuss emerging treatments currently receiving rigorous clinical research effort, special considerations for the treatment of chronic migraine in children and adolescents, and avenues for improving existing treatments and expanding access to evidence-based care.

Abstract
BackgroundThe optimal dose of galcanezumab for patients with migraine remains uncertain. Therefore, we conducted a network meta-analysis to assess the comparative effectiveness of various doses of galcanezumab for this group of patients.MethodsA systematically search was implemented in several databases including the PubMed, Ovid MEDILNE, Ovid EMBASE, and Cochrane Library from inception of the databases until Aug 31, 2020. Only randomized clinical trials of adults with migraine that assessed galcanezumab therapy and reported clinical outcomes were included. The primary efficacy outcome was monthly change in migraine headache days (MHDs). The primary safety outcome was treatment-emergent adverse events (TEAEs).ResultsOverall, eight randomized clinical trials included 4,720 patients, were assessed in our systematic review. In terms of efficacy, galcanezumab 120 mg and 240 mg significantly reduced monthly MHDs (MD -2.02, 95% CrI -2.62 to -1.42; MD -2.06, 95% CrI -2.74 to -1.36, respectively) compared to the placebo. In terms of safety, galcanezumab 120 mg, 150 mg, and 240 mg significantly increased incidences of adverse events (RR 1.11, 95% CrI 1.03 to 1.20; RR 1.85, 95% CrI 1.27 to 2.81; RR 1.15, 95% CrI 1.06 to 1.24, respectively).ConclusionsGalcanezumab 240 mg offers the first level in terms of efficacy outcomes and galcanezumab 150 mg ranks the first level in terms of increasing treatment-emergent adverse events among adult patients with migraine. Attention should be devoted to the potential risk of adverse events, especially for injection site pain when the drug is administered subcutaneously.

Abstract
Migraine is a prevalent disorder and a cause of high disability, influenced by modifiable and non-modifiable risk factors. Comorbid and psychiatric illnesses are prevalent in migraine patients and should be considered when choosing preventive drugs. There have been unforeseen problems with the use of preventive treatment of migraine with oral drugs, mainly due to side-effects that cannot be tolerated and lack of efficacy, leading to high discontinuation rates. Anti-CGRP monoclonal antibodies (mAbs) have shown better tolerance profiles, based on the low dropout rates in clinical trials due to adverse events. First-line therapy is a term most expressed in some medical specialties that adopt standardized protocol treatments and may not be suitable for treating migraine. Regarding efficacy, mAbs don't seem to perform much better than the current prophylactic oral drugs in reduction of monthly migraine days compared to placebo. Monoclonal antibodies against CGRP pathway have been prescribed recently, which raises some concern about their safety in the long term. Only side effects observation will confirm whether CGRP blockade causes susceptibility to severe side-effects, at least to specific subpopulations. CGRP may play a role in regulating uteroplacental blood flow and myometrial and uterine relaxation, as well as blood pressure control, raising the suspicion that its blockade could cause complications during pregnancy. Recent guidelines retain the recommendation of starting preventive treatment of migraine with oral drugs. Both the fact that it is new and costs are the reason why guidelines recommend the prescription of mAbs only after failure of at least two oral drugs.

Abstract
BACKGROUND Migraine is a common and disabling primary headache disorder, associated with many medical comorbidities, highly prevalent, with complex treatment and management. Currently, monoclonal antibodies targeting the trigeminal sensory neuropeptide, calcitonin gene-related peptide (CGRP), are available. The aim of this protocol is to provide a review comparing the effects and safety profile of different monoclonal antibodies in migraine patients. METHODS The literature search will be performed through the MEDLINE, Embase, CENTRAL, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP), Web of Science and Scopus databases, following the PICO strategy. Real World studies and randomized clinical trials assessing the effect of monoclonal antibodies against CGRP interventions (erenumab, eptinezumab, fremanezumab and galcanezumab) on monthly migraine days (MMD), monthly headache days (MHD), headache impact test (HIT-6) and triptan days of use (TriD) will be included. In Real World studies, the DerSimonian and Laird method will be used to calculate pooled estimates of the mean change difference and in randomized clinical trials, a network meta-analysis will be performed to estimate the comparative effects of different monoclonal antibodies against CGRP. RESULTS The findings of this study will be reported in a peer-reviewed journal. CONCLUSIONS This study will provide evidence to health professionals on the efficacy and safety of different monoclonal antibodies against CGRP on the outcomes studied.

Abstract
Background Evidence showed the supplementation of vitamin D might have beneficial effects for migraine patients. We aimed to investigate the causal effects of serum vitamin D levels on migraine risk using two-sample Mendelian randomization (MR) method. Methods A total of 184 independent genetic instruments for serum vitamin D levels were selected from a study in 417,580 Europeans from UK biobank. Six variants from an independent study were obtained to perform replication analysis. Summary-level data for migraine were obtained from three studies with 48,975 migraine cases, 28,852 migraine cases and 10,536 migraine cases, respectively. Results The estimated odds ratios (ORs) per standard deviation increase in circulating vitamin D levels based on the three migraine datasets were 0.948 (95% CI = 0.883-1.016, p = 0.133), 0.902 (95% confidence intervals [CI] = 0.825-0.986, p = 0.023), and 0.880 (95% CI = 0.786-0.984, p = 0.025), respectively. Using pooled migraine summary data with no sample overlap, MR analysis showed per standard deviation increase in circulating vitamin D levels was significantly associated with a decreased migraine risk (OR = 0.916, 95% CI = 0.859-0.977, p = 0.008). Multivariable MR analyses, sensitivity analyses and replication analysis confirmed the association. MR analyses showed similar estimates for migraine with aura and migraine without aura but with wider 95% CIs. Mediation analysis showed the effect of vitamin D on migraine risk via pathway of serum calcium was corresponding to an OR of 1.003 (95% CI = 1.001-1.005) and a proportion mediated of 3.42%. The reverse MR analysis showed migraine might not affect vitamin D levels. Conclusion This two-sample MR study showed genetically determined increased circulating vitamin D levels are associated with decreased migraine risk. The effect seems consistent across different migraine subtypes. In addition, the role of serum calcium in mediating the association between vitamin D and migraine is negligible. Future large well-designed randomized trials are warranted to assess the effects of vitamin D supplementation for migraine patients, especially in those with vitamin D deficiency.

Abstract
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.

Abstract
BACKGROUND Migraine is a highly prevalent primary headache with an unclear pathomechanism. During the last 40 years numerous hypotheses have arisen, among them the theory of the trigeminovascular system is the primary one. It serves as a skeleton in successful preclinical studies and in the development of effective therapeutic options for migraine headache. OBJECTIVE The Brain Prize (awarded annually by the Lundbeck Foundation) is the most prestigious tribute in neuroscience. The winners in 2021 were Lars Edvinsson, Peter Goadsby, Michael Moskowitz and Jes Olesen. They are the fathers of the migraine pathomechanism which led to revolutionary new treatments. This review summarizes their landmark findings. METHODS Data related to this topic were reviewed from PubMed records published between 1979 and May 2021. Searches were based on preclinical and clinical studies in the covered field. The findings were listed in chronological order. From a therapeutic perspective, only randomized controlled trials and meta-analysis were discussed. RESULTS The calcitonin gene-related peptide-related pathogenesis of migraine is based on the activation of the trigeminovascular system. The therapeutic triad for migraine is triptans, gepants and calcitonin gene-related peptide-targeted monoclonal antibodies. CONCLUSION In the past 40 years, the systematic work of leading headache scientists has resulted in robust theoretical and therapeutic knowledge in the preclinical and clinical study of migraine.
