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.

A real-world, observational study of erenumab for migraine prevention in Canadian patients. Headache 2022; 62:522-529. [PMID: 35403223 PMCID: PMC9320807 DOI: 10.1111/head.14291] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2021] [Revised: 02/19/2022] [Accepted: 02/23/2022] [Indexed: 12/01/2022]
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.

Abstract
In this review, the authors provide an overview of erenumab, a monoclonal antibody used for the preventative treatment of episodic migraine by targeting the CGRP pathway. Randomized controlled trials have shown that erenumab is associated with a statistically significant decrease in monthly migraine days in patients with episodic migraine at monthly doses of 70 or 140 mg when given for a period of 9-12 weeks. Post hoc analyses have also shown long-term maintenance of efficacy. Clinical trials have found erenumab at doses of both 70 and 140 mg to have a favorable safety profile. Erenumab faces significant limitations because of its high financial cost. Additional long-term real-world data are needed to understand the role of erenumab in the treatment of migraine.

Abstract
BACKGROUND We aimed at evaluating adverse drug reactions during the post-marketing phase with erenumab as the suspected/interacting drug in Eudravigilance, with the final goal of investigating the consistency of the disproportionality signals (DS) for erenumab in Eudravigilance and the American Food and Drug Administration Adverse Event Reporting System (FDA FAERS) and undetected disproportionality signals from Eudravigilance. RESEARCH DESIGN AND METHODS Eudravigilance was screened in the period from October 2019 to October 2020. Disproportionality measure was performed using the Reporting Odds Ratio (ROR) according to the guidelines by the European Medicine Agency and using sumatriptan as the control group. RESULTS 3381 cases were reported in the study period. Forty DS were identified both in Eudravigilance and FAERS. Sixteen DS were not identified in FAERS, 10 DS were found to have a biological probability and six DS were considered false-positive and potentially related to confounding by indication. The three system organ classes with the highest proportion of adverse events were general disorders and administration site conditions (16.12%), nervous system disorders (15.95%), and gastrointestinal disorders (13.59%). CONCLUSIONS Adverse events reports were mostly reported as non-serious. The co-analysis of multiple spontaneous reported databases unveiled undetected disproportionality signals for erenumab in individual databases. Future studies should be conducted to confirm the associations and potential clinical implications.

Abstract
PURPOSE In two 24-week migraine prevention studies in Japan, erenumab was associated with significantly greater reductions in migraine frequency versus placebo over Weeks 13-24 (primary endpoint). This post hoc analysis evaluated the onset of efficacy within the first 4 weeks after the initiation of erenumab from the 24-week double-blind periods of these studies. METHODS Placebo-adjusted differences in least squares mean (LSM) change from baseline in weekly migraine days (WMD) were assessed weekly in each study and by migraine type (episodic (EM]/chronic [CM]) (Study 20170609). RESULTS A total of 407 patients from Study 20120309 (70 mg: N = 135; 140 mg: N = 136; placebo: N = 136) and 261 patients from Study 20170609 ([EM] 70 mg: N = 78; placebo: N = 81; [CM] 70 mg: N = 52; placebo: N = 50) were included. For Study 20120309, onset of efficacy was observed as early as Week 1 in favor of erenumab versus placebo. Placebo-adjusted differences in LSM (95% confidence interval [CI]) change from baseline in WMD at Week 1 were -0.38 (-0.71 to -0.05; p = .022) and -0.49 (-0.82 to -0.16; p = .004) in favor of erenumab 70 and 140 mg, respectively. For Study 20170609, significant placebo-adjusted differences were observed with erenumab 70 mg at Week 1 in patients with EM (LSM [95% CI]: -0.55 [-0.97 to -0.12; p = .012]), and at Week 2 in patients with CM (LSM [95% CI]: -0.81 [-1.53 to -0.09; p = .028]) and for the overall population (LSM [95% CI]: -0.71 [-1.09 to -0.33; p < .001]). CONCLUSIONS Erenumab treatment significantly reduced WMD compared with placebo. Onset of erenumab efficacy occurred as early as Week 1 in patients with migraine.

Abstract
BACKGROUND Primary headache associated with sexual activity is a rare benign headache disorder that is provoked by sexual excitement. It is a diagnosis of exclusion after the underlying secondary causes have been ruled out. The cause of this headache disorder is still unknown. Cerebral vasospasm, pericranial muscular contraction, hemodynamic and respiratory changes during sexual activity are most commonly listed as possible pathophysiological mechanisms. Several acute and prophylactic options with good clinical response have been described in the case series. CASE REPORT We present a case of a 30-year-old woman with primary headache associated with sexual activity and comorbid with frequent episodic migraine without aura. Both headache disorders were successfully managed with monoclonal antibody against calcitonine gene-related peptide (CGRP) receptor erenumab 70 mg. CONCLUSION The efficacy of erenumab in our case presumes that CGRP might also be an important mediator in facilitating primary headache associated with sexual activity.

Abstract
Background Medication overuse headache significantly contributes to the chronification process and treatment refractoriness of migraine. Currently, abrupt discontinuation of the overused medication still represents the best management strategy for these patients, challenging public health system resources. Methods In this prospective study, chronic migraine and medication overuse headache sufferers with at least 28 days of analgesic consumption per month were included. Assessment of efficacy outcomes at three months were compared among patients who underwent in-hospital abrupt discontinuation of overused acute medication (YES-DETOX group) and patients who did not (NO-DETOX group) before starting an anti-CGRP monoclonal antibody. Results Of 401 patients who received either erenumab or galcanezumab, 28% (n = 111) satisfied inclusion criteria (YES-DETOX n = 28; NO-DETOX n = 83). After three months of treatment, 59% (n = 65; 47/83 YES-DETOX; 18/28 NO-DETOX) patients reverted from medication overuse headache and 51% (n = 57; 42/83 YES-DETOX; 15/28 NO-DEOTX) achieved ≥50% reduction in monthly headache days; yet no statistical differences were observed between the two groups (p = 0.4788 and p = 0.8393, respectively). Monthly consumption of pain medication was the only baseline prognostic factor in multivariate analysis in the overall cohort (p = 0.016). Conclusion Our results support the emerging evidence that anti-CGRP monoclonal antibodies may be effective in medication overuse headache patients irrespective of detoxification, yet further studies are needed to draw definitive conclusions.

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
OBJECTIVE The purpose of this study was to examine changes in the functional impact of migraine following treatment with erenumab, as measured by the Migraine Functional Impact Questionnaire (MFIQ). BACKGROUND The MFIQ, a novel patient-reported outcome (PRO) measuring the impact of migraine on four domains (physical function, social function, and emotional function [PF, SF, and EF]; usual activities [UAs]) and a single item assessing overall impact on UA, was included in phase III trials evaluating erenumab 70 and 140 mg monthly for migraine prevention among people with episodic migraine (EM). METHODS In the ARISE study, 577 patients with EM were randomized to erenumab 70 mg or placebo. In the STRIVE study, 955 patients with EM were randomized to erenumab, 70 mg or 140 mg or placebo. Pairwise comparisons of least-squares mean (LSM) change from baseline in MFIQ scores (with associated 95% confidence interval [CI]) were assessed for each active treatment versus placebo. RESULTS In ARISE, greater reductions from baseline to month 3 were observed for 70 mg versus placebo for PF (LSM [95% CI]: -3.2 [-6.4 to -0.1]; p = 0.046) and EF (-4.0 [-7.3 to -0.7]; p = 0.019) domain scores. In STRIVE, between-group differences also reflected reductions from baseline to the average of months 4-6 that favored erenumab on all four MFIQ domain scores. Reductions in impact for 70 mg compared to placebo were -4.3 (95% CI: -6.8 to -1.7; p < 0.001) for PF, -4.0 (-6.3 to -1.7; p < 0.001) for UA, -3.7 (-6.1 to -1.2; p = 0.003) for SF, and -5.3 (-7.9 to -2.6; p < 0.001) for EF domain scores. Improvements were also observed for 140 mg versus placebo with between-group differences of -5.7 (95% CI: -8.2 to -3.2; p < 0.001) in PF, -5.1 (-7.5 to -2.8; p < 0.001) in UA, -5.0 (-7.4 to -2.6; p < 0.001) in SF, and -7.2 (-9.9 to -4.5; p < 0.001) in EF domain scores. There were also greater improvements in the overall impact on UA score for 70 mg (LSM [95% CI]: -4.3 [-7.0 to -1.7]; p = 0.001) and 140 mg (-5.3 [-8.5 to -3.2]; p < 0.001) versus placebo. CONCLUSIONS The MFIQ measures the frequency of impacts and level of difficulty on multiple functional domains that provide a more complete picture of the effects of migraine. MFIQ scores showed that in comparison with placebo, patients treated with erenumab had greater reductions in the functional impact of migraine, providing insight into treatment benefits that extend beyond improvements in clinical status and health-related quality of life previously reported based on clinical end points and other PROs.

Abstract
BACKGROUND Guidelines for migraine prophylaxis suggest stopping medication after 6-12 months to reevaluate treatment appropriateness. The Italian Medicines Agency (AIFA) set a mandatory regulation to stop anti-CGRP (calcitonin gene related protein) pathway monoclonal antibody (anti-CGRP mAbs) treatments for 3 months after 12-months of treatment. Herein, we assess the effects of discontinuation and retreatment of anti-CGRP mAbs in resistant chronic migraine patients, evaluating predictive factors of sustained response. METHODS A monocentric prospective cohort study, enrolling 44 severe (resistant to ≥3 preventive treatments) chronic migraine patients (all with medication-overuse), treated with erenumab (54.5%) or galcanezumab (45.5%) for 12-months, who discontinued treatment for three months and then restarted for one month. RESULTS Overall, patients reported an increasing deteriorating trend during the three months of discontinuation. Monthly migraine days (MMDs), number of analgesics, days with at least one analgesic used, a ≥50% response rate (reduction in MMDs), and MIDAS and HIT-6 total scores, remained lower than baseline values, but increased if compared to month-12 of treatment. All outcome measures decreased again during the month of retreatment. Patients who did not meet criteria for restarting treatment had lower MIDAS (p=0.03) and HIT-6 (p=0.01) scores at baseline and better outcome measures during discontinuation compared to patients who restarted treatment. CONCLUSIONS In most patients, the 3-month discontinuation of anti-CGRP mAbs resulted in progressive migraine deterioration that was rapidly reverted by retreatment. However, one-fourth of patients, who reported better quality of life indices before treatment, showed a sustained benefit during discontinuation and did not need retreatment.

Abstract
Objective: We reported gender-specific data on the efficacy and safety of erenumab, a monoclonal antibody antagonizing the calcitonin gene-related peptide (CGRP) receptor. Methods: Our pooled patient-level analysis of real-world data included patients treated with erenumab and followed up for 12 weeks. We considered the following outcomes at weeks 9–12 of treatment compared with baseline: 0–29%, 30–49%, 50–75%, and ≥75% responder rates, according to the decrease in monthly headache days (MHDs), rate of treatment stopping, change in MHDs, monthly migraine days (MMDs), monthly days of acute medication and triptan use, and Headache Impact Test-6 (HIT-6) score from baseline to weeks 9–12. Outcomes were compared between men and women by the chi-squared test or t-test, as appropriate. An analysis of covariance (ANCOVA) was performed to identify factors influencing the efficacy outcomes. Results: We included 1,410 patients from 16 centers, of which 256 (18.2%) were men. Men were older than women and had a lower number of MHDs at baseline. At weeks 9–12, compared with baseline, 46 (18.0%) men had a ≥75% response, 75 (29.3%) had a 50–74% response, 35 (13.7%) had a 30–49% response, and 86 (33.6%) had a 0–29% response, while 14 (5.5%) stopped the treatment. The corresponding numbers for women were 220 (19.1%), 314 (27.2%), 139 (12.0%), 402 (34.8%), and 79 (6.8%). No gender difference was found in any of the outcomes. The ANCOVA showed that gender did not influence the efficacy of outcomes. Conclusion: We found that erenumab is equally safe and effective in men compared with women after 12 weeks.

Abstract
BACKGROUND Erenumab (ERE) is the first anti-calcitonin gene related peptide (CGRP) receptor monoclonal antibody approved for migraine prevention. A proportion of patients does not adequately respond to ERE. METHODS Prospective, multicenter study involving 110 migraine patients starting ERE 70 mg monthly. Baseline socio-demographics and migraine characteristics including mean monthly migraine days (MMDs), migraine-related burden (MIDAS and HIT-6 scales) and use of abortive medications during 3 months before and after ERE start were collected. Real-time PCR was used to determine polymorphic variants of calcitonin receptor-like receptor and receptor activity-modifying protein-1 genes. Logistic regression models were used to identify independent predictors for 50% (50-RESP) and 75% (75-RESP) responder patients. RESULTS At month 3, MMDs decreased from 17.2 to 9.2 (p<0.0001), 59/110 (53.6%) patients were 50-RESP, and 30/110 (27.3%) were 75-RESP. Age at migraine onset [OR (95%CI):1.062(1.008-1.120), p=0.024], number of failed preventive medications [0.753(0.600-0.946) p=0.015], and MIDAS score [1.011(1.002-1.020) p=0.017] were associated with 75-RESP. Among the genetic variants investigated, RAMP1 rs7590387 was found associated to a lower probability of being 75-RESP [per G allele OR (95%CI): 0.53(0.29-0.99), p=0.048], but this association did not survive adjustment for confounding clinical variables [per G allele, 0.55 (0.28-1.10), p=0.09]. CONCLUSIONS In this real word study treatment with ERE significant reduced MMDs. Number of failed preventive medications, migraine burden, and age at migraine onset predicted response to ERE. Larger studies are required to confirm a possible role of RAMP1 rs7590387 as genetic predictor of ERE efficacy.

Abstract
During a 1-year compassionate use program, 156 patients with migraine self-administered a monthly dose of erenumab 140 mg with a subcutaneous autoinjector. Main inclusion criteria were: ≥ 4 migraine days/month and ≥two prior prophylactic treatment failures. The patients covered the migraine severity spectrum from episodic migraine (EM) (n = 80) to chronic migraine (CM) (n = 76). During the 3rd month of treatment, monthly headache days decreased by 45.7% in EM and 35.5% in CM. The 50% responder rate for reduction in monthly headache days was significantly higher in EM (55%) than in CM (43%) (p = 0.05). In both the migraine subgroups, the clinical improvement vs. baseline was already significant during the 1st month of treatment (p < 0.001). There were also significant reductions in mean headache severity, duration, and monthly days with acute drug intake. The 30% responder rate at 3 months was 60% in CM and 54.1% of patients reversed from CM to EM. The therapeutic effect was maintained at 12 months when 50% responder rates, considering discontinuation for lack of efficacy or adverse effects as 0% response, still were 51% in EM and 41% in CM. A total of 10 patients with EM (12.5%) and 23 patients with CM (30.3%) had discontinued treatment, considering the treatment as ineffective. At 3 months, 48% of patients reported non-serious adverse events among which the most frequent was constipation (20.5%); corresponding figures at 12 months were 30 and 15%. Discontinuation due to an adverse effect for the entire 12 month period was rare (3.8%). The lower efficacy in CM than in EM was mainly due to a very low 50% responder rate in patients with CM with continuous pain (13%) as compared to CM with pain-free periods (58%) (p < 0.001). Similarly, the 50% responder rate was lower in patients with ≥two prior prophylactic treatment failures (40.5%) compared to those with two failures (70%) (p < 0.05). There was no significant efficacy difference between low (4-7 migraine days/month, n = 22) and high frequency (8-14 days, n = 59) EM nor between patients with CM with (n = 50) or without (n = 26) acute medication overuse. Erenumab had no effect on the frequency of auras. Taken together, erenumab 140 mg monthly was highly effective for migraine prophylaxis over the whole severity spectrum of the disease, except in patients with continuous headaches. Its effect is significant after the first injection, quasi-maximal after the second injection, and does not wear off after 12 months. The most frequent adverse effect was constipation. These results are compared to those published for erenumab in the pivotal randomized placebo-controlled trials and to those reported in several recent real-world studies.

Abstract
WHAT IS KNOWN AND OBJECTIVE Erenumab is a monoclonal antibody for the prophylactic treatment of migraine. We describe the first cases of xerostomia probably induced by this drug. CASE SUMMARY We present two patients diagnosed with chronic migraine who started treatment with erenumab and presented with dry mouth after the first and second dose. WHAT IS NEW AND CONCLUSION Xerostomia is not described as an adverse reaction in the drug's technical datasheet. A search was made in PubMed including 'erenumab', 'fremanezumab', 'galcanezumab', 'xerostomia', and no results were found. It is necessary to identify this potential adverse reaction in order to estimate its prevalence and possible impact on patients' quality of life.

Abstract
OBJECTIVE To describe the real-world treatment persistence (defined as the continuation of medication for the prescribed treatment duration), demographics and clinical characteristics, and treatment patterns for patients prescribed erenumab for migraine prevention in Canada. BACKGROUND The effectiveness of prophylactic migraine treatments is often undermined by poor treatment persistence. In clinical trials, erenumab has demonstrated efficacy and tolerability as a preventive treatment, but less is known about the longer term treatment persistence with erenumab. METHODS This is a real-world retrospective cohort study where a descriptive analysis of secondary patient data was conducted. Enrollment and prescription data were extracted from a patient support program for a cohort of patients prescribed erenumab in Canada between September 2018 and December 2019 and analyzed for persistence, baseline demographics, clinical characteristics, and treatment patterns. Descriptive analyses and unadjusted Kaplan-Meier (KM) curves were used to summarize the persistence and dose escalation/de-escalation at different timepoints. RESULTS Data were analyzed for 14,282 patients. Median patient age was 47 years, 11,852 (83.0%) of patients were female, and 9443 (66.1%) had chronic migraine at treatment initiation. Based on KM methods, 71.0% of patients overall were persistent to erenumab 360 days after treatment initiation. Within 360 days of treatment initiation, it is estimated that 59.3% (KM-derived) of patients who initiated erenumab at 70 mg escalated to 140 mg, and 4.4% (KM-derived) of patients who initiated at 140 mg de-escalated to 70 mg. CONCLUSIONS The majority of patients prescribed erenumab remained persistent for at least a year after treatment initiation, and most patients initiated or escalated to a 140 mg dose. These results suggest that erenumab is well tolerated, and its uptake as a new class of prophylactic treatment for migraine in real-world clinical practice is not likely to be undermined by poor persistence when coverage for erenumab is easily available.

Abstract
BACKGROUND Switching between antibody classes might be a treatment option in migraine patients who have not responded to one class of a CGRP-(receptor) monoclonal antibody (mAb), but there are no efficacy data so far. In this real-world analysis, we assessed the treatment response to a CGRP-mAb in patients that have previously failed the CGRP-receptor-mAb erenumab. METHODS We analyzed retrospective headache diary data of 78 patients with migraine who switched between CGRP-mAbs classes at four German headache centers either due to lack of efficacy or intolerable side effects. Among these, we identified 25 patients who did not respond to erenumab after three treatment cycles (defined as <30% reduction of monthly headache days) and had complete headache documentation at least one month before and during both treatments. We assessed the ≥30% responder rate at month three after switching from erenumab to a CGRP-mAb (galcanezumab or fremanezumab) (primary endpoint). Secondary endpoints included ≥50% responder rate, monthly headache days, and monthly days with acute medication use. In an exploratory subgroup analysis patients were stratified for daily and non-daily headache. RESULTS The switch from erenumab to a CGRP-mAb led to a ≥30% response in one-third (32%) of the patients after three treatment cycles. A ≥50% response was achieved in 12% of the patients. Monthly headache days were reduced in month three compared to baseline (20.8 ± 7.1 to 17.8 ± 9.1; p = 0.009). Stratified analysis revealed that no patient with daily headache (n = 9) responded to the treatment switch, while a 30% response was achieved by 50% of patients with non-daily headache (n = 16). CONCLUSION Our findings demonstrate that a relevant proportion of erenumab non-responders might benefit from a treatment switch to a CGRP-mAb. Switching seems to be a promising treatment option especially in migraine patients with non-daily headache.

Abstract
OBJECTIVES Migraine is a highly prevalent neurological disorder. The most characteristic symptom of migraine is moderate to severe recurrent headache along with other neurological symptoms. In this study, we modeled the potential reduction in migraine days and corresponding avoided productivity losses if erenumab was prescribed to the patient population indicated for prophylactic migraine treatment (≥ 4 monthly migraine days [MMDs]) in Germany from 2020 to the end of 2027. METHODS We simulated the incremental benefits of erenumab against the standard of care. Response rates, transition probabilities, discontinuation rates, and productivity estimates were derived from the erenumab clinical trial program. Patients had a probability of residing in 1 of 7 states, given the MMDs in addition to the probability of death. Based on accrued MMDs in every cycle, days of absenteeism and presenteeism for paid and unpaid work were derived. Paid work was monetized according to gross value added using the human capital approach, whereas unpaid work was valuated according to the proxy good method. In addition, downstream macroeconomic effects were captured using value-added multipliers. Direct medical costs were concomitantly calculated. RESULTS Our results show that prescribing erenumab for the indicated population in Germany could lead to a reduction of 166 million migraine days annually and reduce productivity losses in the range of €27 billion. This includes €13.1 billion from direct productivity and €13.5 billion from economic value chain effects. CONCLUSIONS This study highlights the macroeconomic effects of a systematic introduction of novel inhibitors of the calcitonin gene-related peptide pathway for migraine in Germany.

Abstract
Migraine is a prevalent medical condition and the second most disabling neurological disorder. Regarding its pathophysiology, calcitonin gene-related peptide (CGRP) plays a key role, and, consequently, specific antimigraine pharmacotherapy has been designed to target this system. Hence, apart from the gepants, the recently developed monoclonal antibodies (mAbs) are a novel approach to treat this disorder. In this review we consider the current knowledge on the mechanisms of action, specificity, safety, and efficacy of the above mAbs as prophylactic antimigraine agents, and examine the possible adverse events that these agents may trigger. Antimigraine mAbs act as direct scavengers of CGRP (galcanezumab, fremanezumab, and eptinezumab) or against the CGRP receptor (erenumab). Due to their long half-lives, these molecules have revolutionized the prophylactic treatment of this neurovascular disorder. Moreover, because of their physicochemical properties, these agents are hepato-friendly and do not cross the blood-brain barrier (highlighting the relevance of peripheral mechanisms in migraine). Nevertheless, apart from potential cardiovascular side effects, the interaction with AMY1 receptors and immunogenicity induced by autoantibodies against mAbs could be a concern for the safety of long-term treatment with these molecules.

Abstract
Background and purpose New prophylactics for migraine, targeting calcitonin gene‐related peptide (CGRP), have recently emerged. Real‐world data are important for a comprehensive understanding of treatment response. We assessed the consistency of response to erenumab, a monoclonal CGRP receptor antibody, in a real‐world setting, in order to determine which patients may be considered responders in clinical practice. Methods All erenumab‐treated patients (n = 100) completed a time‐locked daily electronic diary, and an automated algorithm was used to monitor treatment response. Monthly migraine days (MMD), non‐migrainous headache days, days of acute medication use (MAMD), well‐being and coping with pain were assessed for a 6‐month period. The primary outcome was reduction in MMD compared to baseline. Results The numbers of MMD and MAMD decreased in all months, in both episodic and chronic migraine patients, compared to baseline (p < 0.001), while general well‐being (p < 0.001) and coping with pain (p < 0.001) also improved. Of all patients, 36% had an MMD reduction of ≥50% in ≥3/6 months, and 6% had such a reduction in all 6 months. For a ≥30% MMD reduction, the figures were 60% and 24%, respectively. Almost 90% of patients with an average MMD reduction of ≥30% over the first 3 months had a sustained response in the last 3 months. In addition, 20% of patients without an initial response (average <30%), had a delayed response (average ≥30%) in the last 3 months. Conclusion Erenumab was effective in migraine patients who were highly refractory to previous prophylactics. As a practical guideline, we propose that treatment be continued for at least 6 months and that patients with a ≥30% MMD reduction in at least half of the treatment period should be considered to be responders.

Abstract
BACKGROUND Reversible cerebral vasoconstriction syndrome is normally triggered by vasoactive compounds or illicit drugs. A new type of migraine preventive medication blocks calcitonin gene-related peptide utilizing monoclonal antibodies. Calcitonin gene-related peptide is a potent vasodilator for the cerebrovascular system. Could blocking calcitonin gene-related peptide be a trigger for cerebral artery vasospasm in patients susceptible to developing reversible cerebral vasoconstriction syndrome (migraine patients) or in individuals using vasoactive compounds? We present a case of reversible cerebral vasoconstriction syndrome occurring after calcitonin gene-related peptide monoclonal antibody treatment. CASE REPORT A 43-year -old woman with a history of episodic migraine developed an acute headache with orgasm two days after taking her second injection of erenumab. Ten days after erenumab injection she developed a thunderclap headache while completing a high intensity workout. These new headaches were only left sided. Computed tomography angiography demonstrated mild to moderate areas of narrowing involving the left middle and anterior cerebral arteries, concerning for reversible cerebral vasoconstriction syndrome. She denied exposure to any known reversible cerebral vasoconstriction syndrome precipitant medication or illicit drugs. She did endorse recent exposure to high altitude prior to erenumab therapy. She was started on verapamil 40 mg three times per day and her headache ceased within 24 h of initiating treatment. A repeat CT angiogram completed 4 weeks after the initial study noted resolution of the areas of vessel stenosis. CONCLUSION A case of reversible cerebral vasoconstriction syndrome developing after treatment with a calcitonin gene-related peptide monoclonal antibody is presented. The timing of the new type of headache occurring 2 days post erenumab injection suggests a possible cause and effect relationship. Reversible cerebral vasoconstriction syndrome as a possible treatment-related complication to the usage of calcitonin gene-related peptide monoclonal antibodies needs to be studied further.

Abstract
Background Erenumab is a human anti‐calcitonin gene‐related peptide receptor monoclonal antibody approved for migraine prevention. We sought to further assess the temporal patterns of response to erenumab in patients with chronic migraine (CM), specifically the onset and sustainability of monthly migraine day (MMD) response. Methods This is a post hoc analysis of a 12‐week, randomized, double‐blind, placebo‐controlled study of erenumab for migraine prevention in patients with CM (≥15 headache days/month, including ≥8 migraine days/month). Onset and sustainability were assessed according to MMD reduction from baseline, with the following response categories: responders (≥50% reduction), partial responders (≥30% and <50%), or nonresponders (<30%). Results Among the erenumab 140 mg group (n = 187), 54.0% (101/187) achieved a response at any month during the study with a median time to onset of monthly response of 1 month. This improvement was maintained in most patients with continued treatment. An initial response was achieved at Month 1 by 28.3% (53/187) of patients; 69.8% (37/53) of whom maintained a response at Months 2 and 3. Although many patients responded early, some patients required longer treatment to achieve a response; 79.4% (27/34) of initial partial responders and 21.0% (21/100) of initial nonresponders subsequently achieved a response. Similar findings were observed for the erenumab 70mg group (n = 188). Conclusion A majority of erenumab‐treated patients with CM who achieved an initial response at Month 1 sustained this benefit. Many patients responded later with continued treatment. Our data support recommendations to assess outcomes after ≥3 months of preventive treatment with erenumab in CM.

Abstract
Raynaud's phenomenon is a rare side effect of CGRP monoclonal antibodies. These molecular treatments are a relatively new class of drugs for the prevention of migraine. It is likely that we will see this side effect more often in the future. Patients with a background of Raynaud's phenomenon may experience worsening of their symptoms if started on these treatments.

Abstract
OBJECTIVE Erenumab is a monoclonal antibody acting against calcitonin gene-related peptide receptor and approved for the preventive treatment of chronic migraine. The aim of the present study is to identify clinical predictors of good response in patients with chronic migraine and medication overuse-headache. MATERIAL AND METHODS This was a retrospective single-center not funded study. Enrolled patients were affected by chronic migraine and medication overuse-headache treated with erenumab monthly, up to 1 year. At 1 year, patients were classified as good responders if they displayed a ≥50% reduction in the number of headache days per months compared to the baseline. RESULTS After 1 year, a significant improvement in the number of headache days per months, analgesic consumption, 6-items headache impact test, and migraine disability assessment questionnaire scores were obtained compared to the baseline. Patients who obtained a ≥50% reduction in the number of headache days per month compared to the baseline displayed a longer history of medication overuse-headache, a higher number of painkillers taken per month at the baseline and a higher number of failed preventive treatments in the past. CONCLUSIONS Patients with longer medication overuse-headache duration, higher analgesic intake, and a higher number of previous preventive treatment failures may receive less benefit with erenumab.
