Abstract
BACKGROUND Chronic migraine (CM) is a disabling and hard-to-treat condition, associated with high disability and high cost. Among the preventive treatments, botulinum toxin A (BoNT-a) and monoclonal antibodies against the calcitonin gene-related protein (anti-CGRP mAbs) are the only disease-specific ones. The assessment of the disease burden is complex, and among others, tools such as the allodynia symptoms checklist (ASC-12) and headache impact test (HIT-6) are very useful. This exploratory study analysed the impact of these two therapies on migraine burden. METHODS The RAMO study was a multicentre, observational, retrospective investigation conducted in two headache centres: the Fondazione IRCCS Istituto Neurologico Carlo Besta (Milan) and the Fondazione Policlinico Campus Bio-Medico (Rome). This study involved patients with chronic migraine treated with mAbs or BoNT-A. We conducted a subgroup exploratory analysis on HIT-6 and ASC-12 scores in the two groups. The Wilcoxon rank-sum test, Fisher's exact test, and ANOVA were performed. RESULTS Of 126 patients, 36 on mAbs and 90 on BoNT-A had at least one available follow-up. mAbs resulted in a mean reduction of -11.1 and -11.4 points, respectively, in the HIT-6 at 6 and 12 months, while BoNT-A was reduced -3.2 and -3.6 points, respectively; the mAbs arm resulted in mean reductions in ASC-12 at 6 and 12 months of follow-up of -5.2 and -6.0 points, respectively, while BoNT-A showed lesser mean changes of -0.5 and -0.9 points, respectively. The adjusted analysis confirmed our results. CONCLUSIONS In this exploratory analysis, anti-CGRP mAbs showed superior effectiveness for HIT-6 and ASC12 compared to BoNT-A. Reductions in terms of month headache days (MHD), migraine disability assessment test (MIDAS), and migraine acute medications (MAM) were clinically relevant for both treatments.

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: Phase II/III randomized clinical trials (RCTs) are vulnerable to many types of bias beyond randomization. Insights into the reporting quality of RCTs involving migraine patients treated with monoclonal antibodies targeting the calcitonin gene-related peptide system (anti-CGRP MAbs) are currently lacking. Our aim was to analyze the reporting quality of phase II/III RCTs involving migraine patients treated with anti-CGRP MAbs. Methods: A systematic search was performed on the PubMed and EMBASE databases, according to PRISMA guidelines, for relevant RCTs in either episodic or chronic migraine prevention. Additionally, an adapted version of the 2010 CONSORT statement checklist was utilized. The ROBvis online tool was used to document the risk of bias. Results: From the initially identified 179 articles, we finally found 31 RCTs that were eligible for evaluation. The average CONSORT compliance was 88.7% (69.7-100%), while 93.5% (N = 29) of the articles had a compliance greater than 75%. Twenty-eight CONSORT items were reported in more than 75% of the articles. The average compliance of the analyzed RCTs was 93.9% for Galcanezumab, 91.3% for Fremanezumab, followed by 85.4% for Erenumab and Eptinezumab studies. Implementation of the ROB2 tool showed some concerning "missing information" arising from the inadequate reporting. Specifically, 50% of the studies (N = 16) were categorized as having inadequate information regarding the randomization process. Conclusions: Adequate reporting quality was disclosed in the evaluated RCTs with anti-CGRP MAbs in migraine prevention. However, some methodological issues need to be highlighted to be addressed in future studies assessing the efficacy of new molecules targeting CGRP or other candidate pathways implicated in migraine pathophysiology.

Abstract
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most common monogenic form of cerebral small vessel disease, caused by a mutation in the NOTCH3 gene on chromosome 19. The main clinical features include migraine (often with aura), early onset, recurrent subcortical ischemic strokes, mood disturbances, and cognitive impairment, frequently leading to dementia and disability with a reduction in life expectancy. Cerebral chronic global hypoperfusion, due to impaired cerebrovascular reactivity, seems to play a primary role in CADASIL. Migraine is the most common early feature of the disease, and to date, there are no consensus guidelines for treatment. Given the vasomodulatory influence of many antimigraine drugs, there is concern about their use in this disease. In particular, the calcitonin gene-related peptide (CGRP) system serves as a vasodilatory protective mechanism during cerebral and cardiac ischemia. Blocking this system could exacerbate ischemic events. Herein, we describe two CADASIL patients who were treated with the calcitonin gene-related peptide (CGRP) receptor antagonist erenumab for chronic migraine, reporting a significant reduction in the frequency of attacks and intensity of pain, and an improvement in quality of life without adverse effects.

Abstract
Aim: To compare the efficacy of erenumab versus rimegepant as preventive treatment for patients with episodic and chronic migraine using an anchor-based matching-adjusted indirect comparison. Methods: Patients from two phase II/III trials for erenumab (NCT02066415 and NCT02456740) were pooled and weighted to match on the baseline effect modifiers (age, sex, race, baseline monthly migraine days [MMDs], and history of chronic migraine [CM]) reported in the phase II/III trial for rimegepant (NCT03732638). Four efficacy outcomes were compared between the two erenumab regimens (70 mg and 140 mg) and rimegepant, including changes in MMDs from baseline to month 1 and month 3, changes in Migraine-Specific Quality of Life Questionnaire role function - restrictive domain score from baseline to month 3, and change in disability from baseline to Month 3. Results: Compared with rimegepant, erenumab 70 mg was associated with a statistically significant reduction in MMDs at month 3 (-0.90 [-1.76, -0.03]; p = 0.042) and erenumab 140 mg was associated with statistically significant reductions in MMDs at month 1 (-0.94 [-1.70, -0.19]; p = 0.014) and month 3 (-1.28 [-2.17, -0.40]; p = 0.005). The erenumab regimens also had numerical advantages over rimegepant for other efficacy outcomes. Conclusion: In the present study, we found that erenumab had a more favorable efficacy profile than rimegepant in reducing MMDs at month 1 and month 3 for migraine prevention. These results may help with decision-making in clinical practice and can be further validated in future clinical trials or real-world studies.

Abstract
BACKGROUND AND PURPOSE Multiple drugs targeting the calcitonin gene-related peptide (CGRP) receptor have been developed for migraine treatment. Here, the effect of the monoclonal antibody erenumab on CGRP-induced vasorelaxation was investigated in human isolated blood vessels, as well as the effect of combining erenumab with the small molecule drugs, namely rimegepant, olcegepant, or sumatriptan. EXPERIMENTAL APPROACH Concentration-response curves to CGRP, adrenomedullin or pramlintide were constructed in human coronary artery (HCA) and human middle meningeal artery (HMMA) segments, incubated with or without erenumab and/or olcegepant. pA2 or pKb values were calculated to determine the potency of erenumab in both tissues. To study whether acutely acting antimigraine drugs exerted additional CGRP-blocking effects on top of erenumab, HCA segments were incubated with a maximally effective concentration of erenumab (3 μM), precontracted with KCl and exposed to CGRP, followed by rimegepant, olcegepant, or sumatriptan in increasing concentrations. KEY RESULTS Erenumab shifted the concentration-response curve to CGRP in both vascular tissues. However, in HCA, the Schild plot slope was significantly smaller than unity, whereas this was not the case in HMMA, indicating different CGRP receptor mechanisms in these tissues. In HCA, rimegepant, olcegepant and sumatriptan exerted additional effects on CGRP on top of a maximal effect of erenumab. CONCLUSIONS AND IMPLICATIONS Gepants have additional effects on top of erenumab for CGRP-induced relaxation and could be effective in treating migraine attacks in patients already using erenumab as prophylaxis.

Abstract
BACKGROUND Calcitonin gene-related peptide (CGRP) antagonists are recently approved for the treatment of migraine. AIM The main aim of the current study was to find out the association of CGRP antagonists with RP using data mining algorithms integrated with network pharmacological approaches. RESEARCH DESIGN AND METHODS The individual case safety reports were extracted using OpenVigil2.1-MedDRA-V17 (2004Q1-2022Q3), the United States Adverse Event Reporting System (US FAERS). The data mining algorithms i.e. reporting odds ratio (ROR) with 95% confidence and proportionality reporting ratio (PRR) with associated chi-square value were calculated along with a minimum of three ICSRs to identify the signal. Further, the network was constructed using Cytoscape 3.7.2. Finally, molecular docking was performed using Glide, Schrodinger Inc. RESULTS The PRR ≥2 with a linked chi-square value ≥4, add up of co-occurrence ≥3, and a lower limit of 95% confidence interval of ROR exceeding 2 indicates a positive signal of RP. Further, the network pharmacological and molecular docking results have shown the involvement of insulin-like growth factor 1-receptor (IGF1R) pathways. CONCLUSION The RP is recognized as a novel signal with all CGRP antagonists.

Abstract
Background Calcitonin gene-related peptide monoclonal antibodies (CGRP mAbs) are indicated for migraine prevention in the United States. Limited data comparing real-world treatment patterns for CGRP mAbs are available. Objective To compare the treatment patterns among patients with migraine initiating galcanezumab, fremanezumab, and erenumab. Methods This retrospective study included adult patients with one or more claims for a self-injectable CGRP mAb (galcanezumab, fremanezumab, or erenumab), with continuous enrollment in medical and pharmacy benefits for 12 months pre-index and 6 and 12 months post-index using MerativeTM MarketScan® Commercial and Medicare databases from May 2017 through March 2021. Propensity-score matching was used to address confounding by observed covariates. Outcomes analyzed included proportion of days covered (PDC), medication-possession ratio (MPR), persistence (≤60-day gap), treatment discontinuation, and switch to a non-index drug. Descriptive X2 and t-test analyses were conducted. Results At the 12-month follow-up, matched galcanezumab and fremanezumab cohorts each comprised 2674 patients and the galcanezumab and erenumab cohorts 3503 each. The mean (SD) PDC and MPR were both 0.6 (0.3) across all cohorts. Based on PDC ≥0.80 and MPR ≥0.80, a greater proportion of galcanezumab vs fremanezumab (46.2% vs 43.7%, p=0.053; 46.8% vs 44.3%, p=0.053) and galcanezumab vs erenumab (46.2% vs 44%, p=0.156; 46.7% vs 44.5%, p=0.262), respectively, initiators were adherent. Compared to galcanezumab, fremanezumab (248.0 days vs 236.5 days, p=0.001), and erenumab (247.8 days vs 241.7 days, p=0.061) initiators had lower mean persistence. Galcanezumab initiators were less likely to discontinue treatment than fremanezumab (47.8% vs 51.7%, p=0.005) and erenumab (47.7% vs 50.2%, p=0.040) initiators. Across cohorts, most switchers initiated onabotulinum toxin A as subsequent treatment. Similar results were observed for 6-month follow-up cohorts. Conclusion Patients with migraine who initiated treatment with galcanezumab showed higher persistence and lower treatment discontinuation rates than those initiating either fremanezumab or erenumab.

Abstract
BACKGROUND AND PURPOSE Calcitonin gene-related peptide (CGRP) is involved in migraine pathophysiology. CGRP can signal through two receptors. The canonical CGRP receptor comprises the calcitonin receptor-like receptor and receptor activity-modifying protein 1 (RAMP1); the AMY1 receptor comprises the calcitonin receptor with RAMP1. Drugs that reduce CGRP activity, such as receptor antagonists, are approved for the treatment and prevention of migraine. Despite being designed to target the canonical CGRP receptor, emerging evidence suggests that these antagonists, including erenumab (a monoclonal antibody antagonist) can also antagonise the AMY1 receptor. However, it is difficult to estimate its selectivity because direct comparisons between receptors under matched conditions have not been made. We therefore characterised erenumab at both CGRP-responsive receptors with multiple ligands, including αCGRP and βCGRP. EXPERIMENTAL APPROACH Erenumab antagonism was quantified through IC50 and pKB experiments, measuring cAMP production. We used SK-N-MC cells which endogenously express the human CGRP receptor, and HEK293S and Cos7 cells transiently transfected to express either human CGRP or AMY1 receptors. KEY RESULTS Erenumab antagonised both the CGRP and AMY1 receptors with an ~20-120-fold preference for the CGRP receptor, depending on the cells, agonist, analytical approach and/or assay format. Erenumab antagonised both forms of CGRP equally, and appeared to act as a competitive reversible antagonist at both receptors. CONCLUSION AND IMPLICATIONS Despite being designed to target the CGRP receptor, erenumab can antagonise the AMY1 receptor. Its ability to antagonise CGRP activity at both receptors may be useful in better understanding the clinical profile of erenumab.

Abstract
Chronic migraine is a disabling neurovascular disorder that ranks amongst the top causes of years lived with disability worldwide. The duration and the frequency of migraine affect cognitive and affective domains, inducing worsening of memory, executive functions, orientation and causing anxiety. Population-based studies report a worrying level of resistance to treatments. Therefore, this study aims: 1) to assess efficacy of monoclonal antibodies (mAbs) directed towards the calcitonin gene-related peptide (CGRP) or its receptor (CGRP-R) for chronic migraine resistant to current preventatives; 2) to design a clinical trial protocol to evaluate the efficacy and safety of combination therapy utilizing anti-CGRP/CGRP-R together with onabotulinumtoxin A in patients suffering from resistant chronic migraine; 3) to provide a molecular rationale for combination therapy. A controlled trial is warranted as pooled analysis of real-world data from our group highlighted that combined treatment provides ≥50% reduction vs. baseline (onabotulinumtoxin A) of monthly headache days (MHDs) in up to 58.8% of patients, but there has been only sparse application of this combined therapy to date. The mAbs chosen are: erenumab, because its combination effect with onabotulinumtoxin A improved symptoms in 65% of patients; eptinezumab, due to its faster action. The results highlight that early diagnosis of migraine improves therapeutic outcomes with mAbs alone, confirming their effectiveness and the need for an adequately powered clinical trial evaluating the safety and potential superior effectiveness of eptinezumab/erenumab and onabotulinumtoxin A together.

Abstract
OBJECTIVE The treatment landscape for the prevention of migraine has rapidly evolved in recent years with the advent of calcitonin gene-related peptide therapy, including erenumab. The objective of this study was to assess patient-reported treatment satisfaction among erenumab users. METHODS This retrospective, cross-sectional study used data from the 2019 US National Health and Wellness Survey collected during March-July 2019. Respondents self-reporting physician-diagnosed migraine and currently using erenumab were analyzed. Treatment satisfaction was measured on a seven-point Likert scale. Data were further reported by the duration of erenumab treatment. Data on respondents' socio-demographic characteristics and treatment patterns were also collected. RESULTS Overall, 67 respondents using erenumab with or without other migraine preventives for up to 1 year were included in the analysis. The mean (standard deviation) age was 46.7 (12.9) years. Most of the respondents were women (86.6%), White (74.6%), and commercially-insured (67.2%). Notably, 40.3% had ≥1 comorbidity per the Charlson Comorbidity Index. Approximately half of the respondents were college graduates and employed (49.3% each). Among the 67 respondents, 46 received erenumab exclusively. Across both cohorts, the percentage of respondents who were satisfied with erenumab treatment was slightly higher among those with a longer treatment duration (overall erenumab cohort: 63.6%, 69.6%, and 75.8% for 0-<3, 3-<6, and 6-12 months, respectively; erenumab monotherapy cohort: 62.5%, 71.4%, and 87.5% for 0-<3, 3-<6, and 6-12 months, respectively). Treatment patterns before switching to erenumab revealed that most respondents had used ≥1 preventive treatment for migraine (80.6%; 54/67), over two-thirds (33/54) of whom had ≥2 treatment failures owing to nonresponse. CONCLUSION Satisfaction was high among long-term erenumab users, indicating that those using erenumab for a longer duration are more satisfied. Furthermore, this study provided insights on the basic socio-demographics, disease characteristics, and health behaviors of erenumab users as well as their treatment patterns before switching to erenumab.

Abstract
OBJECTIVE To assess healthcare costs and healthcare resource utilization (HCRU) among adult patients who newly initiated erenumab in the United States. METHODS This retrospective, non-interventional analysis included adult patients (aged ≥18 years) newly initiating erenumab and who had three consecutive monthly claims for erenumab (11/1/2017-9/1/2019) from the Komodo Health database. Outcomes included migraine-related and all-cause costs, use of other preventive/acute migraine medications, and HCRU. All outcomes were compared during the 180-day pre- versus the 180-day post-index periods. Cost outcomes were also assessed for longer periods including post-index Days 91-270 and monthly mean post-index costs for the longest time of continuous insurance enrollment. RESULTS Overall, 1839 patients with migraine were included for analysis. Compared to the 180-day pre-index period, an increase in total migraine-related costs (+$2639; p < 0.0001), migraine-related prescription costs (+$3435, p < 0.0001), all-cause total costs (+$2977; p < 0.001), and all-cause prescription costs (+$4102; p < 0.0001) were observed during the 180-day post-index period after adjusting for covariates. Conversely, reduction in migraine-related medical costs (-$896; p < 0.0001), and significantly lower odds of migraine-related emergency room visits (odds ratio [OR] 0.60, 95% confidence interval [CI] 0.44-0.82; p = 0.001), migraine-related office visits (OR 0.58, 95% CI 0.53-0.64; p < 0.0001), and migraine-related neurologist visits (OR 0.69, 95% CI 0.63-0.75; p < 0.0001) were observed during the 180-days post-index period. There were significant decreases in the odds of having overall preventive migraine medications (OR 0.81, 95% CI 0.75-0.87; p < 0.0001), acute-migraine medications (OR 0.92, 95% CI 0.85-1.00; p = 0.038), and triptan (OR 0.79, 95% CI 0.73-0.85; p < 0.0001) during the 180-day post-index period. Sensitivity analyses on cost outcomes found no statistically significant differences in pre-index migraine-related costs compared to post-index migraine-related costs when assessing longer post-index follow-up periods. CONCLUSION Initiation of therapy with a novel treatment is often associated with an increase in overall healthcare costs due to the entrance costs associated with novel therapy. For a chronic condition such as migraine, cost versus health benefits should be evaluated over a long period (e.g., ≥2 years) to better understand the true benefits of therapy. Data from this study suggest that the entrance cost for erenumab, the primary driver of the high post-index prescription costs gets mitigated by reduced medical costs over long-term follow-up. The results indicate better disease management in adult patients with migraine, which should be an important consideration for both patients and payors, as these findings have shown an offset between migraine-related prescription and medical costs.

Abstract
BACKGROUND In this study, we fill this gap in knowledge by updating the safety profile of ubrogepant and rimegepant via disproportionality analysis in the Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS), a US-based database registering spontaneous reports. RESEARCH DESIGN AND METHODS ASCII files of quarterly extraction of FAERS data were downloaded from the FDA website up to the 3rd quarter (Q3) of 2021 (last accessed 03/02/2022). Disproportionality analysis was done using the Reporting Odds Ratio (ROR) as a disproportionality measure. RORs of all AEs related to ubrogepant and rimegepant in FAERS were calculated in comparison with those related to erenumab. Drug-event pairs with a frequency ≤ 2, were removed according to European Medicine Agency (EMA)'s procedures. RESULTS In total, 2010 and 3691 individual case safety reports (ICSRs) recorded in FAERS reported ubrogepant and rimegepant, respectively, as suspect drugs. Ten disproportionality signals for ubrogepant and 25 disproportionality signals for rimegepant were identified; these were mostly related to psychiatric, neurological, gastrointestinal, skin, vascular, and infectious type of adverse events. CONCLUSIONS New safety aspects related to the treatment of ubrogepant and rimegepant using disproportionality analysis from spontaneous reporting databases were identified. Further studies are needed to confirm these findings.

Abstract
OBJECTIVE To evaluate the effect of treatment with anti-calcitonin gene-related peptide (CGRP; receptor) antibodies on visual hypersensitivity in patients with migraine. BACKGROUND Increased visual sensitivity can be present both during and outside migraine attacks. CGRP has been demonstrated to play a key role in light-aversive behavior. METHODS In this prospective follow-up study, patients treated for migraine with erenumab (n = 105) or fremanezumab (n = 100) in the Leiden Headache Center were invited to complete a questionnaire on visual sensitivity (the Leiden Visual Sensitivity Scale [L-VISS]), pertaining to both their ictal and interictal state, before starting treatment (T0) and 3 months after treatment initiation (T1). Using a daily e-diary, treatment effectiveness was assessed in weeks 9-12 compared to a 4-week pre-treatment baseline period. L-VISS scores were compared between T0 and T1. Subsequently, the association between the reduction in L-VISS scores and the reduction in monthly migraine days (MMD) was investigated. RESULTS At 3 months, the visual hypersensitivity decreased, with a decrease in mean ± standard deviation (SD) ictal L-VISS (from 20.1 ± 7.7 to 19.2 ± 8.1, p = 0.042) and a decrease in mean ± SD interictal L-VISS (from 11.8 ± 6.6 to 11.1 ± 7.0, p = 0.050). We found a positive association between the reduction in MMD and the decrease in interictal L-VISS (β = 0.2, p = 0.010) and the reduction in ictal L-VISS (β = 0.3, p = 0.001). CONCLUSION A decrease in visual hypersensitivity in patients with migraine after treatment with anti-CGRP (receptor) antibodies is positively associated with clinical response on migraine.

Abstract
OBJECTIVE Assess the long-term efficacy and safety of erenumab in patients with chronic migraine with acute medication overuse. BACKGROUND Overuse of acute medication in patients with chronic migraine has been linked to greater pain intensity and disability and may diminish the effectiveness of preventive therapies. METHODS This 52-week open-label extension study followed a 12-week double-blind placebo-controlled study in which patients with chronic migraine were randomized 3:2:2 to placebo or once-monthly erenumab 70 mg or 140 mg. Patients were stratified by region and medication overuse status. Patients received erenumab 70 mg or 140 mg throughout or switched from erenumab 70 to 140 mg (based on protocol amendment to augment safety data at higher dose). Efficacy was assessed in patients with and without medication overuse at parent study baseline. RESULTS Of 609 patients enrolled in the extension study, 252/609 (41.4%) met the criteria for medication overuse at parent study baseline. At Week 52, the mean change in monthly migraine days from parent study baseline was -9.3 (95% confidence interval: -10.4, -8.1 days) in the medication overuse subgroup versus -9.3 (-10.1, -8.5 days) in the non-medication overuse subgroup (combined erenumab doses); proportion of patients achieving ≥50% reduction in monthly migraine days at Week 52 was 55.9% (90/161; 48.2%, 63.3%) versus 61.3% (136/222; 54.7%, 67.4%), respectively. Among baseline users of acute migraine-specific medication, the mean change in monthly migraine-specific medication days at Week 52 was -7.4 (-8.3, -6.4 days) in the medication overuse subgroup versus -5.4 (-6.1, -4.7 days) in the non-medication overuse subgroup. Most patients (197/298; 66.1%) in the medication overuse subgroup transitioned to non-overuse status by Week 52. Erenumab 140 mg was associated with numerically greater efficacy than erenumab 70 mg across all endpoints. No new safety signals were identified. CONCLUSION Long-term erenumab treatment demonstrated sustained efficacy and safety in patients with chronic migraine with and without acute medication overuse.

Abstract
BACKGROUND Patients diagnosed with New Daily Persistent Headache and Persistent Post-Traumatic Headache belong to a heterogeneous group of primary and secondary headache disorders, with the common clinical feature that these conditions start abruptly, continue unabated, and are refractory to conventional migraine preventive treatments. OBJECTIVE This is a real-world, medium-term audit to explore whether erenumab improves quality of life in a pooled group of 82 abrupt-onset, unremitting and treatment refractory patients, where the diagnosis is new daily persistent headache and persistent post-traumatic headache in the majority of cases. METHODS Eighty-two patients were treated with erenumab every 28 days over a two to three-year period, beginning in December 2018. These patients were "longstanding chronic" and refractory with a median of eight (IQR 4-12) prior failed migraine preventive treatments and median duration of disease of seven (IQR 3-11) years. The starting dose of erenumab was 70 mg in 79% of cases and 140 mg in the remaining patients (individuals with a BMI of more than 30). All patients were asked to complete three migraine specific Quality of Life questionnaires or Patient Reported Outcome Measures before starting treatment and typically at 3-12 intervals until the end of June 2021 or cessation of treatment. The Patient Reported Outcome Measures included: Headache Impact Test-6, Migraine Associated Disability Assessment test and Migraine-Specific Quality-of-Life Questionnaire. Patients generally only stayed on treatment after 6-12 months if there was deemed to be an improvement of at least 30% and there were no significant side effects. The longest treated cases have quality of life data for 30 months after starting erenumab. RESULTS Of the 82 patients, 29 (35%) had improvement in Quality of Life scores, with no significant side effects, and wished to stay on treatment. Fifty-three patients (65%) stopped treatment during the first 6-25 months due to lack of efficacy and/or patient reported side effects (n = 33 and n = 17, respectively) or a combination of both, pregnancy planning (n = 2), and lost to follow up (n = 1). CONCLUSION Significant improvements in Quality of Life scores were recorded by one-third of patients over a period of 11-30 months, with a 35% persistence after a median of 26 months of treatment. This contrasts with our recently published, treatment resistant, chronic migraine cohort where the persistence with erenumab treatment was almost 55% after a median time of 25 months.

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.

Abstract
The introduction of monoclonal antibodies (mAbs) directed against the calcitonin gene-related peptide (CGRP), or its receptor (CGRPr), revolutionized migraine management due to their high efficacy and few side effects. Data suggest that the CGRP may even be implicated in circadian rhythm, but studies about the effect of anti-CGRP treatments on sleep are still lacking. The aim of the present study was to assess the effect of erenumab (70 and 140 mg per month), a human mAb directed against CGRPr, on chronotype in chronic migraineurs; secondly, we assessed its efficacy, safety, and the effects on anxiety and depression. Sleep was evaluated using self-administrable questionnaires investigating chronotype, sleep quality, and daytime sleepiness. Migraine diaries and several self-administrable questionnaires regarding headache impact and psychological correlates were evaluated every 3 months during 12 months of treatment. Eighty-eight patients were included; most of them showed a significant reduction in headache frequency and an improvement in psychological symptoms. Moreover, an initial change in chronotype was observed at the three-month assessment from a morning chronotype to an intermediate one; a similar trend remained in the other evaluations, even if it did not reach a statistical significance. Lastly, patients who responded to the treatment showed a progressive sleep efficiency reduction. The present real-life study hypothesized the influence of erenumab on chronotype, representing a link between circadian rhythm, CGRP, and migraine.

Abstract
Migraine is one of the most disabling disorders in the world, associated with poor quality of life. Migraine prevention strategies have increasingly evolved since monoclonal antibodies against the calcitonin gene-related peptide (CGRP), or its receptor, were identified. CGRP is the ideal target of monoclonal antibodies (mAbs). In particular, erenumab is the mAb that has shown good therapeutic efficacy in reducing pain intensity and having high tolerability. In this study, we aimed to investigate the efficacy of erenumab on both cognitive performance and psychological well-being. This was a pilot study with a retrospective design that included 14 subjects (2 males and 12 females), with a mean age of 52.29 ± 9.62, who attended the Headache and Migraine outpatient clinic of the IRCCS Centro Neurolesi Bonino-Pulejo of Messina. The evaluation consisted of measuring cognitive and psychological functioning. Comparing clinical and psychometric test scores between baseline and follow-up, we found a significant improvement in both cognitive performance and quality of life. We also observed a decrease in migraine disability. Our findings have shown improvements in global cognitive performance and quality of life in migraine patients taking erenumab.

Abstract
INTRODUCTION With increased use of erenumab and other calcitonin gene-related peptide antagonists for migraine prevention, increased evidence on long-term efficacy and real-world effectiveness is needed. Some reports of a wearing-off effect or waning efficacy over time have been observed with erenumab use. OBJECTIVE This study evaluated the change in efficacy of erenumab after initial established benefit for migraine prevention in a Veteran population. METHODS This retrospective chart review evaluated patients who were prescribed erenumab for migraine prevention at a Veterans Affairs neurology clinic between June 1, 2018 and May 31, 2021. Patients with an initial 50% or greater reduction in mean monthly headache days (MHDs) by 12 weeks after erenumab 70 mg initiation were then followed forward to determine the change in MHDs until erenumab dose was increased, changed to galcanezumab, or by November 30, 2021 to ensure a minimum 6-month follow-up for all patients. RESULTS Ninety-three patients were included for analysis. A significant reduction in mean MHDs from 16.1 to 5.7 days was found by 12 weeks after erenumab 70 mg initiation (p < 0.0001). Following this initial response to erenumab, 69% of patients experienced a significant increase in MHDs over an average time of 7.8 months and required a subsequent dose increase to erenumab 140 mg or change to galcanezumab. The remaining 31% of patients continued erenumab 70 mg monthly with a further non-statistically significant decline in MHDs. CONCLUSIONS A decrease in efficacy with long-term use of erenumab was observed for the majority of patients evaluated in this analysis. This suggests that patients with initial benefit on lower dose erenumab should be monitored for change to effectiveness.

Abstract
BACKGROUND Due to the recent introduction of new biologic drugs for chronic migraine, a global evaluation in real clinical practice is necessary. OBJECTIVE The objective was to evaluate the effectiveness and safety in real clinical practice of drugs targeting the calcitonin gene-related peptide receptor (CGRPr) in patients with chronic migraine. METHODS Single-center, restrospective study (2019-2022), including patients with chronic migraine treated with erenumab, galcanezumab, or fremanezumab. Effectiveness variables were recorded, namely, number of migraine headache days per month (MHD), Migraine Disability Assessment Scale (MIDAS) score, and Headache Impact Test-6 (HIT-6) score, assessing changes at week 12, 24 from baseline. Toxicity was recorded following the Common Terminology Criteria for Adverse Events (CTCAE) v5.0 criteria. RESULTS In all, 104 patients were included (46.2% erenumab, 41.3% galcanezumab, 12.5% fremanezumab). A reduction in MHD, MIDAS, and HIT-6 was achieved at weeks 12 and 24 with erenumab (p75% at week 24 than those intensified; P = 0.041). There was no difference in efficacy (P = 0.154) or improvement in quality of life (P = 0.783, P = 0.150), but there was greater toxicity (P < 0.001) among nonresponders with erenumab 70 mg versus erenumab 140 mg. CONCLUSIONS The results confirm the effectiveness and safety of anticalcitonin gene-related peptide (CGRP) drugs in real clinical practice. However, the study shows little benefit from erenumab intensification, with similar effectiveness and worse tolerability than the standard dose.

Abstract
BACKGROUND AND PURPOSE Response predictors to erenumab (ERE) in migraine patients would benefit their clinical management. We investigate associations between patients' clinical characteristics and polymorphisms at calcitonin receptor-like receptor (CALCRL) and receptor activity-modifying protein 1 (RAMP1) genes and response to ERE treatment measured as clinically meaningful improvement on the Headache Impact Test-6 (HIT-6) score. METHODS This post hoc analysis of a prospective, multicenter, investigator-initiated study involves 110 migraine patients starting ERE 70 mg/month. Demographics, medical history, and migraine-related burden measured by HIT-6 score were collected during 3 months before and after ERE start. Selected polymorphic variants of CALCRL and RAMP1 genes were determined using real-time polymerase chain reaction. Logistic regression models identified independent predictors for response to ERE, defined as HIT-6 score improvement ≥ 8 points (HIT-6 responders [HIT-6 RESP] vs. HIT-6 nonresponders). RESULTS At Month 3, 58 (52.7%) patients were HIT-6 RESP. Comorbid hypertension predicted a lower probability of being HIT-6 RESP (odds ratio [OR] = 0.160, 95% confidence interval [CI] = 0.047-0.548, p = 0.003). Compared to major alleles, minor alleles CALCRL rs6710852G and RAMP rs6431564G conferred an increased probability of being HIT-6 RESP (for each G allele: OR = 2.82, 95% CI = 1.03-7.73, p = 0.043; OR = 2.10, 95% CI = 1.05-4.22, p = 0.037). RAMP1 rs13386048A and RAMP1 rs12465864G decreased this probability (for each rs13386048A, OR = 0.53, 95% CI = 0.28-0.98, p = 0.042; for each rs12465864G, OR = 0.32, 95% CI = 0.13-0.75, p = 0.009). A genetic risk score based on the presence and number of identified risk alleles was independently associated with HIT-6 RESP (OR = 0.49, 95% CI = 0.33-0.72, p = 0.0003), surviving Bonferroni correction. CONCLUSIONS Response to ERE was associated with comorbid hypertension and specific allelic variants in CALCRL and RAMP1 genes. Results require confirmation in future studies.

Abstract
BACKGROUND Anti-CGRP (receptor) antibodies effectively reduce overall migraine attack frequency, but whether there are differences in effect between perimenstrual and non-perimenstrual migraine days has not been investigated. METHODS We performed a single-arm study among women with migraine. Participants were followed with electronic E-diaries during one (pretreatment) baseline month and 6 months of treatment with either erenumab or fremanezumab. Differences in treatment effect on perimenstrual and non-perimenstrual migraine days were assessed using a mixed effects logistic regression model, with migraine day as dependent variable and treatment, menstrual window and an interaction-term (treatment*menstrual window) as fixed effects and patient as a random effect. RESULTS There was no interaction between the menstrual window and treatment effect, indicating that the reduction in migraine days under treatment was similar during the menstrual window and the remainder of the menstrual cycle (OR treatment 0.44 (0.38;0.51)). CONCLUSIONS Our findings support prophylactic use of anti-CGRP (receptor) antibodies for women with menstrual migraine as this leads to consistent reductions in number of migraine days during the entire menstrual cycle.

Abstract
OBJECTIVE To assess cardiovascular (CV) safety of erenumab in clinical trial patients associated with degree of CV risk. BACKGROUND Hypertension has been considered a theoretical risk associated with the inhibition of the calcitonin gene-related peptide pathway in migraine management, particularly in a patient population with pre-existing CV risk factors. METHODS Data pooled from four double-blind, randomized trials were used to assess blood pressure (BP) changes and CV safety in patients grouped based on 10-year risk of cardiac, cerebrovascular, and peripheral artery disease as no-risk-factors, low-risk (>0% to ≤10%), moderate-risk (>10% to ≤20%), and high-risk (>20%) categories. CV safety was assessed as ischemic cardiovascular and cerebrovascular adverse events (ICCAE). RESULTS There was no apparent difference between placebo- (N = 1032) and erenumab-treatment groups (70 mg, N = 885; 140 mg, N = 504) in clinical worsening of BP category from baseline to Months 1-3 (14% [143/1032] placebo vs. 13% [114/885] and 14% [71/504] for erenumab 70 and 140 mg, respectively) regardless of baseline BP category. The adverse event (AE) profile of erenumab was similar across CV risk categories throughout the long-term analysis. Erenumab-treated patients with high and moderate 10-year CV risk (N = 107) did not experience any ICCAEs during the double-blind treatment period; there was a single ICCAE (a cerebral dural venous sinus thrombosis) observed in the low-risk erenumab group (N = 273). There were no increases in AEs during the long-term extensions of up to 5 years (N = 2499; 3482 patient-years of exposure to erenumab) with exposure-adjusted incidence rates of cardio/cerebrovascular disorder AEs of 0.4, 0.5, 0.0, and 1.1 (per 100 patient-years) for no risk factor (N = 1805), low (N = 492), moderate (N = 121), and high (N = 81) 10-year CV risk groups, respectively. CONCLUSIONS Ischemic CV and cerebrovascular AEs were uncommon and the incidence rates were similar across the 10-year CV risk categories. This analysis helps provide more detail on the CV safety of erenumab.

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 Monoclonal antibodies against calcitonin gene-related peptide (CGRP) or its receptor (anti-CGRP(-R) mAbs) and small-molecule CGRP receptor antagonists (gepants) are new mechanism-based prophylactic drugs developed to address the unmet needs of pre-existing migraine prophylactic medications. However, several uncertainties remain in their real-world applications. METHODS This is a narrative review of the literature on the use of CGRP-targeting novel therapeutics in specific situations, including non-responders to prior therapy, combination therapy, switching, and treatment termination. In the case of lack of available literature, we made suggestions based on clinical reasoning. RESULTS High-quality evidence supports the use of all available anti-CGRP(-R) mAbs (erenumab, galcanezumab, fremanezumab, and eptinezumab) in non-responders to prior therapy. There is insufficient evidence to support or reject the efficacy of combining CGRP(-R) mAbs or gepants with oral migraine prophylactic agents or botulinum toxin A. Switching from one CGRP(-R) mAb to another might benefit a fraction of patients. Currently, treatment termination depends on reimbursement policies, and the optimal mode of termination is discussed. CONCLUSIONS New prophylactic drugs that target the CGRP pathway are promising treatment options for patients with difficult-to-treat migraine. Individualized approaches using a combination of new substances with oral prophylactic drugs or botulinum toxin A, switching between new drugs, and adjusting treatment duration could enhance excellence in practice.

Abstract
BACKGROUND Treatment wearing-off has been reported for calcitonin gene-related peptide-pathway monoclonal antibodies, including erenumab, specifically in the last week of the monthly dosing cycle. OBJECTIVE We sought to determine the consistency of erenumab effect throughout the monthly treatment cycle. METHODS In this post hoc analysis of four pivotal double-blind, randomized controlled studies of erenumab in episodic and chronic migraine, we assessed wearing-off based on change in weekly migraine days at week 4 versus average over weeks 1-3 in each monthly dosing cycle. Analyses were conducted at each monthly dosing cycle in all patients, in responders (≥50% reduction in weekly migraine days), and in consistent responders (response in ≥2monthly cycles). RESULTS There was no evidence of wearing-off in the full study populations of two global studies (N = 946 and N = 656) and two Japan studies (N = 475 and N = 261). In the full study population, mean change in weekly migraine days at week 4 compared with the average over week 1-3 ranged from 0.15 days improvement to 0.19 days worsening in the placebo group and 0.08 days improvement to 0.20 days worsening in the erenumab groups. A subgroup of responders experienced wearing-off, but the extent of wearing-off did not differ between erenumab and placebo groups. The mean change in weekly migraine days at week 4 compared with the average over weeks 1-3 ranged from 0.34 to 0.61 days worsening in the placebo group and 0.27 to 0.78 days worsening in the erenumab groups. Few patients had persistent wearing-off in ≥2 consecutive monthly treatment cycles. For erenumab-treated responders, serum erenumab concentrations were similar among patients experiencing wearing-off and those maintaining response. CONCLUSION No systematic wearing-off with erenumab was identified. Further research is needed to determine if wearing-off reported for some patients in clinical practice reflects a true treatment response pattern or normal fluctuations in migraine frequency.

Abstract
OBJECTIVES The objective of this longitudinal study was to determine whether brain iron accumulation, measured using magnetic resonance imaging magnetic transverse relaxation rates (T2*), is associated with response to erenumab for the treatment of migraine. METHODS Participants (n = 28) with migraine, diagnosed using international classification of headache disorders 3rd edition criteria, were eligible if they had six to 25 migraine days during a four-week headache diary run-in phase. Participants received two treatments with 140 mg erenumab, one immediately following the pre-treatment run-in phase and a second treatment four weeks later. T2* data were collected immediately following the pre-treatment phase, and at two weeks and eight weeks following the first erenumab treatment. Patients were classified as erenumab responders if their migraine-day frequency at five-to-eight weeks post-initial treatment was reduced by at least 50% compared to the pre-treatment run-in phase. A longitudinal Sandwich estimator approach was used to compare longitudinal group differences (responders vs non-responders) in T2* values, associated with iron accumulation. Group visit effects were calculated with a significance threshold of p = 0.005 and cluster forming threshold of 250 voxels. T2* values of 19 healthy controls were used for a reference. The average of each significant region was compared between groups and visits with Bonferroni corrections for multiple comparisons with significance defined as p < 0.05. RESULTS Pre- and post-treatment longitudinal imaging data were available from 28 participants with migraine for a total of 79 quantitative T2* images. Average subject age was 42 ± 13 years (25 female, three male). Of the 28 subjects studied, 53.6% were erenumab responders. Comparing longitudinal T2* between erenumab responders vs non-responders yielded two comparisons which survived the significance threshold of p < 0.05 after correction for multiple comparisons: the difference at eight weeks between the erenumab-responders and non-responders in the periaqueductal gray (mean ± standard error; responders 43 ± 1 ms vs non-responders 32.5 ± 1 ms, p = 0.002) and the anterior cingulate cortex (mean ± standard error; responders 50 ± 1 ms vs non-responders 40 ± 1 ms, p = 0.01). CONCLUSIONS Erenumab response is associated with higher T2* in the periaqueductal gray and anterior cingulate cortex, regions that participate in pain processing and modulation. T2* differences between erenumab responders vs non-responders, a measure of brain iron accumulation, are seen at eight weeks post-treatment. Less iron accumulation in the periaqueductal gray and anterior cingulate cortex might play a role in the therapeutic mechanisms of migraine reduction associated with erenumab.

Abstract
Background Medication-overuse headache is highly prevalent in tertiary care centers. It may be a cause or consequence of the overuse of symptomatic medications for migraine attacks. Objective We aimed to compare the efficacy of anti-CGRP monoclonal antibodies (mAbs) added to conventional pharmacological treatments in patients with chronic migraine (CM) and medication overuse headache (MOH). Methods A cross-sectional, prospective, randomized, open study with real-world comparison groups of patients was carried out. The sample consisted of 200 patients with CM and MOH, who received the same approach to withdraw overused medications, started preventative treatment, and either did or did not receive mAbs. Results A total of 172 patients (126 women and 46 men) were included in the study and divided into two groups: group one consisting of 58 patients (control) and group two of 114 patients who used mAbs added to conventional pharmacological agents. The mean age was 44.1 ± 13.6 years, ranging from 18 to 78 years. In the 3 months follow-up after starting the treatment, both groups presented headache frequency reduction, but those with monoclonal antibodies had a significantly higher reduction in the number of headache days and symptomatic medication intake when compared to the control (p < 0.0001). Conclusions The addition of an anti-CGRP monoclonal antibody to the treatment for medication overuse headaches in chronic migraineurs may result in decreasing headache frequency and symptomatic medication use when compared to conventional treatments with drugs.

Abstract
OBJECTIVE To assess the available clinical and economic evidence of erenumab vs onabotulinumtoxinA for chronic migraine (CM) and present de-novo indirect treatment comparisons (ITCs) based on available clinical trial data. METHODS We conducted ITCs based on results from the pivotal 295 trial (NCT02066415) of erenumab vs placebo and published aggregate data from the PREEMPT 1 (NCT00156910) and PREEMPT 2 (NCT00168428) trials of onabotulinumtoxinA vs placebo. ITCs were conducted for CM patients with and without prior administration of onabotulinumtoxinA and among CM patients with ≥3 prior preventive treatment failures. Efficacy was assessed based on responder rates of ≥50% reductions in monthly headache days (MHDs) and monthly migraine days (MMDs) as well as change from baseline in both MHDs and MMDs. RESULTS Among patients with CM, 140 mg erenumab was associated with a reduction of 1.2 MHD (p = .092) and a reduction of 1.0 MMD (p = .174) compared to onabotulinumtoxinA at Week 12. Among onabotulinumtoxinA-naïve patients, erenumab was associated with a reduction of 1.8 MHD (p = .026) and 1.4 MMD (p = .080) at Week 12. Among patients that had received ≥3 prior preventive treatments, the odds ratios comparing erenumab vs onabotulinumtoxinA were 1.7 for ≥50% responder rates based on reductions in MHD (p = .155) and 1.7 for ≥50% responder rates based on reductions in MMD (p = .140). CONCLUSION These findings suggest directional benefits (although not reaching the threshold of statistical significance) associated with erenumab vs onabotulinumtoxinA for the preventive treatment of CM. Evidence from this study may inform healthcare stakeholders in treatment selection and optimization for patients with CM.

Abstract
Objective To report the efficacy of different anti-calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAbs) on headache frequency, intensity, and duration. Background Blockade of CGRP receptors or neuropeptide with anti-CGRP mAbs have been successfully used for several years for the prevention of chronic and episodic migraine. The response is usually assessed by improvement seen in the number of days with headache per month. However, clinical praxis indicates that sole reliance on the frequency of headaches might be insufficient to interpret the efficacy of these treatments. Methods Retrospective review of a case with a meticulous headache diary who has tried three different anti-CGRP mAbs for chronic migraine prevention. Results The patient has been diagnosed with chronic migraine and was first treated with erenumab, followed by fremanezumab and thereafter galcanezumab due to several reasons. In addition to significant improvement in all three parameters analyzed with anti-CGRP mAb treatment, the most important and valuable effect on the patient's quality of life was decreased duration and frequency of headaches. At present, the patient is receiving fremanezumab treatment with an excellent tolerability. Conclusion There is a clear need for careful follow-up and detailed daily records of headaches showing the frequency, duration, and severity for the evaluation of anti-CGRP mAbs treatment. This study shows the importance of this information in order for medical professionals to make an informed decision regarding the best course of anti-CGRP mAbs treatment in cases of side effects or lack of efficacy.

Abstract
Migraine is a potentially disabling disorder, yet it remains underdiagnosed and undertreated. The release of the neuropeptide calcitonin gene-related peptide (CGRP) in the trigemino-cerebrovascular system plays a vital role in the evolution of migraine. It enhances peripheral sensitization by mediating neurogenic inflammation and also influences central sensitization. The majority of the drug classes available for migraine prophylaxis are nonspecific and associated with numerous side effects and drug interactions. Anti-CGRP monoclonal antibodies (mAb) are an innovative therapeutic class that fulfills the need for more efficacious and tolerable preventive therapy. While erenumab is a mAb to the CGRP receptor, eptinezumab, fremanezumab, and galcanezumab bind to the CGRP molecule. They decrease the number of headache days and improve disability. Upper respiratory tract infection, nausea, constipation, pain at the site of injection, and fatigue are the associated side effects. CGRP mAbs are an excellent advancement in translational research and are a promising addition in migraine therapy. This article discusses the recent advances in the development of the CGRP mAbs.

Abstract
OBJECTIVE To perform a systematic review of real-world outcomes for anti-CGRP-mAbs. METHODS Following the PRISMA guidelines, we searched PubMed for real-world data of erenumab, galcanezumab, fremanezumab, or eptinezumab in patients with migraines. RESULTS We identified 134 publications (89 retrospective), comprising 10 pharmaco-epidemiologic and 83 clinic-based studies, 38 case reports, and 3 other articles. None of the clinic-based studies provided follow-up data over more than one year in more than 200 patients. Findings suggest that there are reductions in health insurance claims and days with sick-leave as well as better treatment adherence with anti-CGRP-mAbs. Effectiveness, reported in 77 clinic-based studies, was comparable to randomized controlled trials. A treatment pause was associated with an increase in migraine frequency, and switching to another antibody resulted in a better response in some of the patients. Adverse events and safety issues were addressed in 86 papers, including 24 single case reports. CONCLUSION Real-world data on anti-CGRP-mAbs are limited by retrospective data collection, small patient numbers, and short follow-up periods. The majority of papers seem to support good effectiveness and tolerability of anti-CGRP-mAbs in the real-world setting. There is an unmet need for large prospective real-world studies providing long-term follow-ups of patients treated with anti-CGRP-mAbs.

Abstract
OBJECTIVE To assess whether dual therapy with erenumab and onabotulinumtoxinA (BoNTA) was more effective than erenumab alone in chronic migraine. BACKGROUND Calcitonin gene-related peptide (CGRP) is crucial in migraine. Erenumab binds to the canonical CGRP receptor in Aδ-fibers, and BoNTA prevents the release of CGRP from meningeal and extracranial C-fibers. It is still unknown whether dual therapy is more effective. METHODS This was a retrospective study in a Headache Unit. There was a thorough revision of charts of patients receiving erenumab from December 2019 to March 2021. The cohort was divided into three groups according to BoNTA at the start of erenumab: (1) WBT: were on BoNTA and maintained it as dual therapy; (2) WoBT: were on BoNTA and discontinued; (3) NoBT: were not on BoNTA. Primary endpoint was reduction in monthly headache days (MHD) at 12 weeks. Secondary endpoints were percent improvement and ≥50% reduction in MHD. RESULTS Of 237 charts reviewed, 187 met the inclusion criteria. Seventy-three (39%) were included in WBT, 44 (23.5%) in WoBT, and 70 (37.4%) in NoBT. The reduction in MHD was less with dual therapy [WBT 4.7 ± 7.68, WoBT 5.12 ± 7.98 (p = 0.80), NoBT 8.21 ± 7.84 p = 0.009]. The percentage of improvement was higher in the erenumab-alone group [NoBT 35%, WoBT 22.3% (p = 0.92), WBT 21.7% (p = 0.001)]. The probability of achieving a ≥ 50% reduction in MHD was lower in WBT than in WoBT (OR 0.66, p = 0.35) and in the NoBT group (OR 0.57, p = 0.14). CONCLUSIONS Our findings suggest that dual therapy is less effective than erenumab alone. However, since the design has multiple limitations, further prospective studies are required to validate these data.

Abstract
Background Controlled and real-world evidence have demonstrated the efficacy of calcitonin gene related peptide (CGRP) monoclonal antibodies (MABs) in migraine. However, data on the over-one-year sustained effectiveness of CGRP MABs in resistant chronic migraine (CM) is sparse. Methods This is a two-year real-world prospective analysis of an ongoing single centre audit conducted in patients with resistant CM. Patients received monthly erenumab for six months before assessing its effectiveness. Responders were considered those who achieved at least 30% reduction in monthly migraine days (MMD) by month 6, compared to baseline. Secondary outcomes were also analysed, including changes of the Headache Impact Test version 6 (HIT-6). Results One hundred sixty-four patients [135 (82.3%) females; mean age 46 SD 14) years] were included in the audit and 160 patients analysed. Patients had failed a mean of 8.4 preventive treatments at baseline. At month 6, 76 patients (48%) were 30% responders to erenumab, 50 patients (31%) were 50% responders and 25 (15%) were 75% responders. The mean reduction in MMD at month 6 was 7.5 days compared to baseline (P < 0.001). At month 12 and month 18, 61 patients (38%) and 52 patients (33%) remained 30% responders respectively. At month 24, 36 patients (23%) remained 30% responders, 25 patients (16%) and 13 patients (8%) were respectively 50% and 75% responders. Compared to 95% of patients at baseline, at months 6, 12 and 24, 46%, 29% and 16% of responders respectively had severe disability. At least one adverse event at month 6, 12, 18 and 24 was reported by 49%, 19%, 11% and 3% of patients. By month 6, 13% of patients discontinued the treatment because of side effects, often constipation. Conclusions Long-term sustained effectiveness of erenumab was reported only by a minority of resistant CM patients. Although more research in resistant migraine is needed, Erenumab can provide long-term meaningful reduction in migraine load and migraine-related disability in some patients.

Abstract
OBJECTIVE To report a case of a woman who continued erenumab for migraine prophylaxis throughout her pregnancy and to review the literature for pregnancy safety data for the calcitonin gene-related peptide (CGRP) receptor and ligand-directed therapies currently approved for migraine prophylaxis in the United States. BACKGROUND Migraine is a common headache disorder that can be significantly disabling. Many people experiencing migraine seek out preventative therapies to improve their quality of life. Unfortunately, currently approved prophylactic agents may not be safe to use during pregnancy, potentially limiting the use of these agents in women of childbearing potential. As the newest class of prophylactic agents for migraine, CGRP agents have limited pregnancy safety data in humans. METHODS A review of the literature was conducted through the PubMed database using the terms pregnancy and either erenumab, fremanezumab, galcanezumab, eptinezumab, rimegepant, or atogepant. Additional sources of information such as prescribing information, assessment reports submitted to the European Medicines Agency (EMA), and manufacturer data were sought. RESULTS One case report was found in the literature documenting a human pregnancy with no adverse effects in the baby after exposure to erenumab. However, the last dose was administered in the second week of pregnancy and discontinued thereafter. The evaluation of 92 safety reports describing maternal exposure prior to or during pregnancy to either erenumab, galcanezumab, or fremanezumab was located. Incidence of miscarriage and congenital anomalies appear to be similar to rates in the general population. CONCLUSIONS The use of erenumab during pregnancy in our patient resulted in no known harm to the child. This case is unique in that the mother continued to receive erenumab throughout the pregnancy. Safety data is lacking regarding the use of these agents during pregnancy, despite their frequent use in women of childbearing potential.

Abstract
BACKGROUND Migraine is a worldwide epidemic neurological disorder that has a significant influence on the quality of life. Migraine attacks are considered to be related to a calcitonin gene-related peptide (CGRP) signaling molecule, and anti-CGRP medications are used to abort and prevent migraine attacks. Erenumab, a monoclonal antibody that targets the CGRP receptor, is the first migraine preventive medication approved by the US Food and Drug Administration. In the present study, we evaluate the efficacy and safety of erenumab. OBJECTIVE This study aims to systematically assess the efficacy and safety of erenumab as a migraine preventive treatment compared to a placebo. METHODS Randomized, placebo-controlled, single or double-blind trials were searched through MEDLINE, Embase, Cochrane Library, and ClinicalTrials.gov up to May 2022. The efficacy outcomes we collected include changes from baseline on monthly migraine days, monthly acute migraine-specific medication days, ≥50% responder rate, ≥75% responder rate, and 100% responder rate at week 12. Safety outcomes include treatment emergent adverse events, serious adverse events, and any adverse event that leads to discontinuation of treatment. The study was registered with PROSPERO (Registry number: CRD42022338861). RESULT In all eight included trials, we found that erenumab (28, 70, and 140 mg) is very effective and has a significantly greater reduction in baseline monthly migraine days (28 mg: mean difference [MD] = -1.1, 95% confidence interval [CI]: -2.0 to -0.2, p = 0.020; 70 mg: MD = -1.4, 95% CI: -1.8 to -1.1, p < 0.001, I2 = 26%; 140 mg: MD = -1.8, 95% CI: -2.1 to -1.4, p < 0.001, I2 = 0%) than placebo at week 12, especially with 140 mg. Otherwise, we found that there were no statistical differences in the occurrence of adverse events (7 mg: risk ratio [RR] = 0.9, 95% CI: 0.7 to 1.2, p = 0.570; 21 mg: RR = 1.0, 95% CI: 0.8 to 1.2, p = 0.730; 28 mg: RR = 0.9, 95% CI: 0.7 to 1.1, p = 0.340; 70 mg: RR = 1.0, 95% CI: 0.9 to 1.0, p = 0.230, I2 = 0%; 140 mg: RR = 1.0, 95% CI: 0.9 to 1.1, p = 0.880, I2 = 40%) between the erenumab and placebo groups. CONCLUSIONS In our study, we found that erenumab, especially at the dose of 140 mg, is an effective and well-tolerated preventive treatment for migraine.

Abstract
BACKGROUND To date, several variables have been associated with anti-CGRP receptor or ligand-antibody response with disparate results. Our objective is to determine whether machine learning (ML)-based models can predict 6, 9 and 12 months response to anti-CGRP receptor or ligand therapies among migraine patients. METHODS We performed a multicenter analysis of a prospectively collected data cohort of patients with migraine receiving anti-CGRP therapies. Demographic and clinical variables were collected. Response rate defined in the 30% to 50% range -or at least 30%-, in the 50% to 75% range -or at least 50%-, and response rate over 75% reduction in the number of headache days per month at 6, 9 and 12 months. A sequential forward feature selector was used for variable selection and ML-based predictive models response to anti-CGRP therapies at 6, 9 and 12 months, with models' accuracy not less than 70%, were generated. RESULTS A total of 712 patients were included, 93% women, aged 48 years (SD=11.7). Eighty-three percent had chronic migraine. ML models using headache days/month, migraine days/month and HIT-6 variables yielded predictions with a F1 score range of 0.70-0.97 and AUC (area under the receiver operating curve) score range of 0.87-0.98. SHAP (SHapley Additive exPlanations) summary plots and dependence plots were generated to evaluate the relevance of the factors associated with the prediction of the above-mentioned response rates. CONCLUSIONS According to our study, ML models can predict anti-CGRP response at 6, 9 and 12 months. This study provides a predictive tool to be used in a real-world setting.

Abstract
Introduction Monoclonal antibodies (mAbs) showed efficacy in migraine prevention. The aim of this study was to check if baseline clinical parameters and cerebral blood flow (CBF) measured by transcranial Doppler (TCD) may help predict mAbs efficacy. Methods Electronic charts of migraineurs treated with erenumab or fremanezumab, with baseline TCD evaluations were collected, including data on migraine type, pain localization, monthly migraine days (MMD), medication overuse headache (MOH), mean blood flow velocity (Vm), and pulsatility index (PI) in cerebral arteries. Results A total of 123 patients were enrolled, mean age 38, 75 years, 87 with chronic migraine, 61 with MOH, 72 were good responders (GR), and reported ≥50% reduction in MMD, 43 ≥75% reduction in MMD. Baseline Vm values in MCAs were significantly lower in GR as compared with non-responders. MAbs responsiveness ≥50% was positively associated with unilateral pain localization (OR: 6.53, 95% CI: 2.01–23.93; p = 0.003) and HIT-6 score (OR: 1.14, 95% CI: 1.01–1.30; p = 0.036) whereas negatively associated with Vm in right MCA (OR: 0.96, 95% CI: 0.92–0.99; p = 0.012), and having no relatives with migraine (OR: 0.40, 95% CI: 0.16–0.95; p = 0.040). Conclusions Baseline Vm in MCA is lower in mAbs GR as compared with non-responders which may reflect increased secretion of CGRP with further vasodilation in GR. Simple clinical features and baseline CBF in anterior circulation might help to predict the patient's responsiveness.

Abstract
INTRODUCTION : In the few last years, a new family of drugs, anti-calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAbs), has been developed for migraine therapy. Anti-CGRP mAbs are highly effective, but the current limited experience with their use and their high-cost warrant establishing certain rules of use. AREAS COVERED The present review provides an overview of the management of migraine patients, especially those who are undergoing treatment with anti-CGRP mAbs. EXPERT OPINION Thanks to new research focused on the pathophysiology of migraine, and the discovery that CGRP plays a key role in its etiopathogenesis, new drugs targeting CGRP have been developed. These drugs have led to a paradigm shift, anticipating new and stimulating possibilities in migraine treatment. While physicians and patients are full of expectation about the advantages of this new family of drugs, there are still obstacles to overcome in order to make the best use of them. It is essential to form multidisciplinary teams that can identify patients who will benefit from these therapies, conducting cost-effective treatments. The follow-up of these therapies in the coming years is paramount due to the lack of experience in the management of these drugs and the peculiarity of disease evolution in migraine patients.

Abstract
Background and purpose Chronic migraine is a highly disabling primary headache disorder that is the most common diagnosis of patients seen at tertiary headache centres. Typical oral preventive therapies are associated with many limitations that impact their therapeutic utility. Erenumab was the first available calcitonin gene‐related peptide monoclonal antibody in the UK. It had proven efficacy in migraine prevention in clinical trials and limited real‐world data in tertiary settings. Methods We audited our first 92 patients (n = 73 females) with severely disabling chronic migraine who were given monthly erenumab 70 mg sc for 6 months between December 2018 and December 2019. Results At 3 months, monthly migraine days were significantly reduced by a median of 4 days, and all other variables also showed significant improvement. The improvement was not affected by baseline analgesic use status. More than half of our patients experienced a clinically meaningful improvement in migraine days. No serious adverse events were reported. Conclusions Our real‐world data with erenumab demonstrate it is effective and well tolerated in managing patients with chronic migraine in a tertiary care setting.

Abstract
Many patients with short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) fail to respond to the first-line treatment of lamotrigine. Additionally, data for other treatments are limited in this rare headache disorder. SUNCT involves activation of the trigeminal nerve which uses the neuropeptide calcitonin gene-related peptide (CGRP); thus CGRP-targeted treatments may be beneficial in this disorder. We present a patient with SUNCT who failed to respond optimally to 10 medications and four surgical treatments. However, she had minimal attacks after erenumab 140 mg was added to carbamazepine 200 mg three times daily and pregabalin 75 mg twice daily. Decreasing any of these three medications worsened her attacks. Our case represents the second case report of a SUNCT patient responding to a CGRP monoclonal antibody, suggesting this treatment may be a consideration in refractory SUNCT.

Abstract
Objectives To assess real‐world effectiveness, safety, and usage of erenumab in Canadian patients with episodic and chronic migraine with prior ineffective prophylactic treatments. Background In randomized controlled trials, erenumab demonstrated efficacy for migraine prevention in patients with ≤4 prior ineffective prophylactic migraine therapies. The “Migraine prevention with AimoviG: Informative Canadian real‐world study” (MAGIC) assessed real‐world effectiveness of erenumab in Canadian patients with migraine. Methods MAGIC was a prospective open‐label, observational study conducted in Canadian patients with chronic migraine (CM) and episodic migraine (EM) with two to six categories of prior ineffective prophylactic therapies. Participants were administered 70 mg or 140 mg erenumab monthly based on physician’s assessment. Migraine attacks were self‐assessed using an electronic diary and patient‐reported outcome questionnaires. The primary outcome was the proportion of subjects achieving ≥50% reduction in monthly migraine days (MMD) after the 3‐month treatment period. Results Among the 95 participants who mostly experienced two (54.7%) or three (32.6%) prior categories of ineffective prophylactic therapies and who initiated erenumab, treatment was generally safe and well tolerated; 89/95 (93.7%) participants initiated treatment with 140 mg erenumab. At week 12, 32/95 (33.7%) participants including 17/64 (26.6%) CM and 15/32 (48.4%) EM achieved ≥50% reduction in MMD while 30/86 (34.9%) participants including 19/55 (34.5%) CM and 11/31 (35.5%) EM achieved ≥50% reduction in MMD at week 24. Through patient‐reported outcome questionnaires, 62/95 (65.3%) and 45/86 (52.3%) participants reported improvement of their condition at weeks 12 and 24, respectively. Physicians observed improvement in the condition of 78/95 (82.1%) and 67/86 (77.9%) participants at weeks 12 and 24, respectively. Conclusion One‐third of patients with EM and CM achieved ≥50% MMD reduction after 3 months of erenumab treatment. This study provides real‐world evidence of erenumab effectiveness, safety, and usage for migraine prevention in adult Canadian patients with multiple prior ineffective prophylactic treatments.
