Real-world effectiveness and safety of erenumab for the treatment of migraine: A systematic review and meta-analysis. Eur J Pharmacol 2024; 976:176702. [PMID: 38823758 DOI: 10.1016/j.ejphar.2024.176702] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Revised: 05/04/2024] [Accepted: 05/29/2024] [Indexed: 06/03/2024]
Abstract
BACKGROUND Migraine is a common and disabling primary headache disorder. Several drugs targeting calcitonin gene-related peptide (CGRP), such as erenumab (an anti-CGRP receptor mAb), have been developed recently. However, the real-world effects of erenumab are not well understood. OBJECTIVE To assess the clinical effectiveness and safety of erenumab for reducing migraine intensity and frequency in the real world. METHODS A systematic search of PubMed, Scopus, Web of Science and the Cochrane Library was conducted from inception to December 2023. Studies estimating the real-world effect of erenumab on monthly migraine days (MMD), monthly headache days (MHD), headache impact test (HIT-6), number of days in medication (NDM), acute monthly intake (AMI), pain intensity (PI) and safety outcomes were included. Meta-analyses of proportions or mean differences were performed. RESULTS Fifty-three studies were included. At 3-months, the effect was -7.18 days for MMD, -6.89 days for MHD, -6.97 for HIT-6, -6.22 days for NDM, -15.75 for AMI, and -1.71 for PI. Generally, the effect at 6- and 12-months increased slightly and gradually. The MMD/MHD response rates revealed that approximately one-third of patients exhibited a response greater than 30%, while one-sixth demonstrated a response exceeding 50%. Additionally, 3-4% of patients achieved a response rate of 100%. Adverse event rates were 0.34 and 0.43 at 6- and 12-months, respectively. CONCLUSION This study provides strong evidence of the effectiveness and safety of erenumab in the real world; to our knowledge, this is the first real-world meta-analysis specific to erenumab. Erenumab represents a solid therapeutic option for physicians.

Abstract
BACKGROUND The present study aimed to investigate the predictive value of calcitonin gene-related peptide (CGRP)-induced migraine attacks for effectiveness to erenumab treatment in people with migraine. METHODS In total, 139 participants with migraine underwent a single experimental day involving a 20-min infusion with CGRP. Following this, the participants entered a 24-week treatment period with erenumab. The primary endpoints were the predictive value of CGRP-induced migraine attacks on the effectiveness of erenumab, defined as ≥50% reduction in monthly migraine days, or ≥ 50% reduction in either monthly migraine or monthly headache days of moderate to severe intensity. RESULTS Among participants with CGRP-induced migraine attacks, 60 of 99 (61%) achieved ≥50% reduction in monthly migraine days during weeks 13-24 with erenumab. Conversely, 13 of 25 (52%) where CGRP infusion did not induce a migraine achieved the same endpoint (p = 0.498). There were no significant differences between the ≥50% reduction in either monthly migraine or monthly headache days of moderate to severe intensity between CGRP-sensitive and non-sensitive participants (p = 0.625). CONCLUSIONS Our findings suggest that the CGRP-provocation model cannot be used to predict erenumab's effectiveness. It remains uncertain whether this finding extends to other monoclonal antibodies targeting the CGRP ligand or to gepants.Trial Registration: The study was registered at ClinicalTrials.gov (NCT04592952).

Abstract
INTRODUCTION Calcitonin Gene-Related Peptide (CGRP)-targeted therapy has revolutionized migraine treatment since its first approval in 2018. CGRP-targeted therapy includes monoclonal antibodies (mAbs) and gepants, which modulate trigeminal nociceptive and inflammatory responses, alleviating pain sensitization involved in migraine pathogenesis. CGRP-targeted therapy is effective not only for migraine but also for other chronic headache disorders that share the CGRP pathway. AREAS COVERED The authors review the latest developments and evidence for CGRP-targeted therapy for episodic migraine and chronic migraine. In addition, the authors discuss the emerging evidence on response prediction, menstrual migraine, vestibular migraine, idiopathic intracranial hypertension, post-traumatic headache, and the relationship between selected migraine comorbidities and CGRP. EXPERT OPINION Since the launch of CGRP-targeted therapy, many practical issues have been raised. Generally, it's safe to combine CGRP-targeted mAbs and gepants; this is an excellent option for patients with partial response. When considering stopping CGRP-targeted therapy, although a disease-modifying effect is likely, the optimal time for discontinuation remains unknown. Finally, beyond migraine, CGRP-targeted therapy may be used for other chronic pain disorders and psychological comorbidities.

Abstract
Calcitonin gene-related peptide neurotransmission was the target for recent development of monoclonal antibodies that effectively prevent attacks of both episodic and chronic migraine. The aim of this narrative review was to offer deeper insight into drug-drug, drug-food and drug-disease interactions of monoclonal antibodies approved for prevention of migraine attacks. For this narrative review, relevant literature was searched for in MEDLINE and Google Scholar databases, covering the 1966-2023 and 2006-2023 periods, respectively. The ClinicalTrials.gov database was also searched for relevant clinical studies whose results had not been published previously in medical journals, covering 2000-2023. Monoclonal antibodies (erenumab, fremanezumab, galcanezumab and eptinezumab) augment prophylactic action of gepants and onabotulinumtoxin A and somewhat increase efficacy of triptans used to abort migraine attacks; however, their adverse reactions may also be augmented. Pharmacokinetic interactions and interactions in general with drugs used for other indications except migraine are negligible, as are drug-food interactions. However, monoclonal antibodies may worsen diseases with already weakened CGRP neurotransmission, Raynaud phenomenon and constipation. Monoclonal antibodies used for prevention of migraine do not engage in significant pharmacokinetic interactions with other drugs; however, they do engage in pharmacodynamic interactions with other anti-migraine drugs, additively augmenting their prophylactic action, but also increasing frequency and severity of adverse reactions, which are a consequence of the CGRP neurotransmission interruption.

Abstract
OBJECTIVE To evaluate clinical characteristics, effectiveness, and tolerability of preventive anti- calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAbs) in the elderly. Anti-CGRP mAbs have demonstrated efficacy and safety in patients with migraine although there is limited information regarding the elderly. DESIGN We performed a multicenter case-control study of cases (patients over 65 years old) and controls (sex-matched patients under 55 years old) with migraine receiving anti-CGRP mAbs. METHODS We included the demographic characteristics, effectiveness-reduction in the number of monthly headache days (MHD) and monthly migraine days (MMD), 30%, 50%, and 75% responder rates-and treatment emergent adverse events (TEAEs). The primary endpoint was the 50% response rate regarding MHD at weeks 20-24; exploratory 50% response predictors in the elderly were evaluated. RESULTS In total, 228 patients were included: 114 cases , 114 controls-. Among cases 84.2% (96/114) were women, 79.8% (91/114) CM; mean age of cases 70.1 years old (range: 66-86); mean age of controls was 42.9 years old(range: 38-49). Cases had a higher percentage of vascular risk factors (P < .05),older age of onset (P < .001) and more reported prior preventive treatments (P < .001). Regarding effectiveness in cases, 50% response rate was achieved by 57.5% (42/73) at 20-24 weeks, with lower reduction in the MHD at 8-12 weeks (5 [7.2], 8 [9.1]; P = .001) and a higher reduction in MMD at 20-24 weeks (10.7 [9.1], 9.2 [7.7]; P = .04) compared to the control group. The percentage of TEAEs was similar in the 2 groups. Diagnosis of episodic migraine (EM) (P = .03) and lower number of MHD at baseline (P = .001) were associated with a 50% response in the elderly in univariate analysis. CONCLUSIONS Our study provides real world evidence of effectiveness and safety of anti-CGRP mAbs for migraine in patients without upper age-limit and possible predictors of anti-CGRP response in the elderly.

Abstract
Background Real-world evidence of erenumab effectiveness in migraine patients in Asia with various comorbidities and multiple previous medication failures is still limited. Methods A 6-month single-center cohort study of 45 patients with episodic or chronic migraine (CM) treated with erenumab was conducted. In the cohort, 60.0% were switching from other calcitonin gene-related peptide monoclonal antibodies (CGRP mAbs), and 66.7% had ≥4 prophylaxis failures. The change in monthly migraine days (MMDs) from baseline and percentages of responders after treatment were calculated. Weekly migraine days (WMDs) were obtained at baseline and at months 1, 2 and 3 and were compared between weeks 2 and 4. Results In total, 36%, 47%, and 63% of patients had a ≥30% response at 1, 3, and 6 months, respectively. The cumulative percentage of patients achieving a ≥30% response over 6 months was 85%. Early responders (average ≥ 30% response at 1-3 months) accounted for 37.8%, 55.6%, and 25.9% of the total, CGRP mAb-naïve, and CGRP mAb-switching groups, respectively. Late responders (average < 30% response at 1-3 months and average ≥ 30% response at 4-6 months) accounted for 46.4%, 37.5%, and 58.8% of nonearly responders in the total, CGRP mAb-naïve, and CGRP mAb-switching groups, respectively. Mild adverse reactions were observed in 5 patients (11.1%). Wearing-off, defined as an increase in the number of WMDs ≥2 between week 2 and week 4, was observed in 2.4-12.5% at months 1-3. Conclusion Erenumab was effective in migraine patients. At least 4-6 months may be preferable for efficacy evaluation in patients switching to erenumab from other CGRP mAbs.

Abstract
INTRODUCTION Although acute and preventive treatments for migraine are commonly given in combination, data on the real-world effectiveness of ubrogepant as an acute treatment when used with an anti-calcitonin gene-related peptide (CGRP) monoclonal antibody (with or without onabotulinumtoxinA) are limited. This analysis sought to evaluate the real-world effectiveness, treatment satisfaction, and optimization of ubrogepant for the acute treatment of migraine when used in combination with an anti-CGRP monoclonal antibody, with or without concomitant onabotulinumtoxinA. METHODS This prospective, multiple-attack, open-label, observational study (COURAGE) assessed meaningful pain relief (MPR), return to normal function (RNF), treatment satisfaction, and acute treatment optimization of ubrogepant (50 or 100 mg) when combined with an anti-CGRP monoclonal antibody, onabotulinumtoxinA, or both in adult users of Migraine Buddy, a migraine tracking application. RESULTS In the ubrogepant and anti-CGRP monoclonal antibody arm (n = 245), following the first ubrogepant-treated attack, 61.6% (151/245) and 80.4% (197/245) of ubrogepant-treated participants achieved MPR at 2 and 4 h post-dose, respectively, and 34.7% (85/245) and 55.5% (136/245) achieved RNF at 2 and 4 h post-dose, respectively. Across up to 10 ubrogepant-treated attacks (N = 1153), MPR was achieved in 51.3% (592/1153) and 73.5% (847/1153) at 2 and 4 h post-dose, respectively. RNF was achieved by 32.2% (371/1153) and 53.2% (613/1153) at 2 and 4 h post-dose. After 30 days, 72.7% (168/231) of participants reported satisfaction (using a 7-point scale) with ubrogepant when used in combination with an anti-CGRP monoclonal antibody, and 79.7% (184/231) of participants achieved acute treatment optimization (defined as moderate-maximum treatment efficacy using the Migraine Treatment Optimization Questionnaire-4). CONCLUSION Real-world ubrogepant use with an anti-CGRP monoclonal antibody was associated with MPR, RNF, satisfaction, and acute treatment optimization.

Simultaneous Comparisons of 25 Acute Migraine Medications Based on 10 Million Users' Self-Reported Records From a Smartphone Application. Neurology 2023; 101:e2560-e2570. [PMID: 38030397 PMCID: PMC10791049 DOI: 10.1212/wnl.0000000000207964] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Accepted: 10/03/2023] [Indexed: 12/01/2023] Open
Abstract
BACKGROUND AND OBJECTIVES Many acute treatment options exist for migraine. However, large-scale, head-to-head comparisons of treatment effectiveness from real-world patient experience reports are lacking. METHODS This is a retrospective analysis of 10,842,795 migraine attack records extracted from an e-diary smartphone application between June 30, 2014, and July 2, 2020. We analyzed 25 acute medications among 7 classes-acetaminophen, nonsteroid anti-inflammatory drugs (NSAIDs), triptans, combination analgesics, ergots, antiemetics, and opioids. Gepants and ditan were not included in this analysis. Different doses and formulations of each medication, according to the generic names, were combined in this analysis. We used a 2-level nested logistic regression model to analyze the odds ratio (OR) of treatment effectiveness of each medication by adjusting concurrent medications and the covariance within the same user. Subgroup analyses were conducted for users in the United States, the United Kingdom, and Canada. RESULTS Our final analysis included 4,777,524 medication-outcome pairs from 3,119,517 migraine attacks among 278,006 users. Triptans (mean OR 4.8), ergots (mean OR 3.02), and antiemetics (mean OR 2.67) were the top 3 classes of medications with the highest effectiveness, followed by opioids (mean OR 2.49), NSAIDs (other than ibuprofen, mean OR 1.94), combination analgesics (acetaminophen/acetylsalicylic acid/caffeine) (OR 1.69, 95% CI 1.67-1.71), others (OR 1.49, 95% CI 1.47-1.50), and acetaminophen (OR 0.83, 95% CI 0.83-0.84), using ibuprofen as the reference. Individual medications with the highest ORs were eletriptan (OR 6.1, 95% CI 6.0-6.3), zolmitriptan (OR 5.7, 95% CI 5.6-5.8), and sumatriptan (OR 5.2, 95% CI 5.2-5.3). The ORs of acetaminophen, NSAIDS, combination analgesics, and opioids were mostly around or less than 1, suggesting similar or lower reported effectiveness compared with ibuprofen. The ORs for 24 medications, except that of acetylsalicylic acid, achieved statistical significance with p < 0.0001, and our nested logistic regression model achieved an area under the curve (AUC) of 0.849. Country-specific subgroup analyses revealed similar ORs of each medication and AUC (United States 0.849, United Kingdom 0.864, and Canada 0.842), demonstrating the robustness of our analysis. DISCUSSION Using a big data approach, we analyzed patient-generated real-time records of 10 million migraine attacks and conducted simultaneous head-to-head comparisons of 25 acute migraine medications. Our findings that triptans, ergots, and antiemetics are the most effective classes of medications align with the guideline recommendations and offer generalizable insights to complement clinical practice. CLASSIFICATION OF EVIDENCE This study provides Class IV evidence that for patients with migraine, selected acute medications (e.g., triptans, ergots, antiemetics) are associated with higher odds of user-rated positive response than ibuprofen.

Galcanezumab Efficacy Through the Dosing Interval in Japanese Patients with Episodic Migraine: Post Hoc Analysis of a Phase 2 Randomized Trial. Neurol Ther 2023; 12:2007-2019. [PMID: 37698836 PMCID: PMC10630272 DOI: 10.1007/s40120-023-00534-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Accepted: 08/10/2023] [Indexed: 09/13/2023] Open
Abstract
INTRODUCTION The efficacy and safety of galcanezumab as a preventive treatment in Japanese patients with episodic migraine was demonstrated in a phase 2, randomized, placebo-controlled trial (conducted December 2016-January 2019). This post hoc analysis assessed the consistency of galcanezumab efficacy through the monthly dosing interval. METHODS Patients with 4-14 migraine headache days/month were randomized (2:1:1, stratified by baseline migraine frequency) to subcutaneous placebo (n = 230), 120-mg galcanezumab (with 240-mg loading dose; n = 115) or 240-mg galcanezumab (n = 114) once monthly for 6 months. Outcomes included change from baseline in weekly migraine headache days, proportion of patients with migraine headache on each day, and proportion of patients with worsening migraine headache days during each month ([average of weeks 3-4] - [average of weeks 1-2] > 0). RESULTS In the 120-mg (approved dose) galcanezumab group, mean change from baseline in weekly migraine headache days was consistent and significantly greater (p < 0.05) than placebo for weeks 1-4; efficacy was consistent when averaged across months 1-6 and in most individual months. Averaged across months 1-6, the proportion of patients with migraine headache was significantly lower with galcanezumab than placebo on every day in both dose groups and was not significantly different between days 2 and 28 with 120-mg galcanezumab (p = 0.161). Within each month, the proportion of patients with migraine headache was generally consistent from days 2-28. The proportion of patients with worsening during the dosing interval did not significantly exceed 50% in any group during any month. CONCLUSIONS This post hoc analysis supports the consistency of efficacy of galcanezumab across 6 months of treatment and suggests that wearing-off within the dosing interval does not occur on a population level in Japanese patients with episodic migraine. TRIAL REGISTRATION ClinicalTrials.gov identifier, NCT02959177.

Abstract
BACKGROUND Migraine is one of four major chronic diseases that cause disability. Decreases in regional cerebral blood flow (rCBF) occur during migraine attacks. Laser therapy is extensively employed in treating other vascular diseases; nevertheless, its effectiveness in migraine management remains largely unknown. Therefore, we evaluated the effect of low-level intravascular laser irradiation of blood (ILIB) therapy in patients with migraine. METHODS We performed an observational case-control study in 24 patients suffering from migraine. Patients were divided into an ILIB treatment group and a traditional rehabilitation group. This study performed clinical assessments and single-photon emission computed tomography (SPECT) prior to and after the treatment and 1 month later. Changes in rCBF-SPECT between groups and between timepoints were compared to clinical outcomes. RESULTS Nine patients undergoing rehabilitation and fifteen patients undergoing ILIB were studied from baseline to 1 month follow-up. The ILIB group, visual analog scale for pain (P = 0.001), Montreal Cognitive Assessment (P = 0.003), and Athens Insomnia Scale (P < 0.001) symptom scores significantly improved after treatment. SPECT imaging showed a 1.27 ± 0.27 fold increase in rCBF after ILIB treatment, and no significant differences in the rehabilitation group. CONCLUSIONS Low-level ILIB therapy is associated with better clinical and vascular outcomes, and may be a feasible treatment option for migraine. Although our sample size was small, our data provide a starting point for migraine laser therapy research.

Abstract
After 35 years since the introduction of the International Classification of Headache Disorders (ICHD), we are living in the era of the second great revolution in migraine therapies. First, discoveries of triptans provided a breakthrough in acute migraine treatment utilizing bench-to-bedside research results on the role of serotonin in migraine. Next, the discovery of the role of neuropeptides, more specifically calcitonin gene-related peptide (CGRP) in migraine attack led to the development of anti-CGRP therapies that are effective both in acute and preventive treatment, and are also able to reduce migraine-related burden. Here, we reviewed the most recent clinical studies and real-world data on available migraine-specific medications, including triptans, ditants, gepants and anti-CGRP monoclonal antibodies. Novel drug targets, such as PACAP and amylins were also discussed. To address the main challenges of migraine therapy, the high heterogeneity of people with migraine, the prevalent presence of various comorbid disorders, and the insufficient medical care of migraine patients were covered. Promising novel approaches from the fields of omics, blood and saliva biomarker, imaging and provocation studies might bring solutions for these challenges with the potential to identify further drug targets, distinguish more homogeneous patient subgroups, contribute to more optimal drug selection strategies, and detect biomarkers in association with headache features or predicting treatment efficacy. In the future, the combined analysis of data of different biomarker modalities with machine learning algorithms may serve precision medicine in migraine treatment.

No Increase in Symptoms Toward the End of the Ocrelizumab Infusion Cycle in Patients With Multiple Sclerosis: Symptom Burden on Ocrelizumab: A Longitudinal Study (SymBOLS). Neurol Clin Pract 2023; 13:e200185.

Abstract
Background and Objectives Some patients with multiple sclerosis (MS) receiving ocrelizumab (OCR) report worsening symptoms toward the end of the 6-month infusion cycle ('wearing off'). The objective of our study was to comprehensively assess changes in symptom burden across 2 consecutive OCR infusion cycles. Methods SYMptom Burden on Ocrelizumab, a Longitudinal Study (SymBOLS; NCT04855617) was an investigator-initiated, 2-center study of patients with MS starting or receiving OCR. Patients' symptoms were assessed with NeuroQoL short forms, SymptoMScreen, and Work Productivity and Activity Impairment Questionnaire at the start-cycle, mid-cycle, and end-cycle time points in each of the 2 infusion cycles. Symptom scores at the 3 time points within each cycle were compared with repeated-measures ANOVA or the Friedman rank-sum test for non-normal variables. The proportions of patients with a meaningful symptomatic change from the start to the end of each infusion cycle were calculated, and patients whose symptoms improved, worsened, and stayed the same from the start to the end of the cycle were compared with respect to demographic and clinical characteristics. Results One hundred three patients with MS provided longitudinal data for analyses (mean age [SD]: 46.7 [12.2] years, 68% female, 33% non-White, disease duration: 15.5 [5] years, 41% with the Extended Disability Status Scale score >3). On a group level, NeuroQoL and SymptoMScreen scores mostly remained stable or even improved slightly toward the end of each cycle. On an individual level, symptoms remained unchanged across either cycle for most patients, and meaningful symptom worsening from the start to the end of the cycle was no more common than improvement. Meaningful change in symptoms in both cycles was very rare and generally in the direction of improvement toward the end cycle. Despite the lack of evidence for symptom worsening with a longer time from infusion, 54% of patients endorsed feeling of "wearing off" at least sometimes, most commonly as an increase in fatigue. Discussion Our prospective study failed to uncover evidence for the worsening of symptoms with a longer time from OCR infusion. These findings cast doubt on the existence of wearing off as a physiologic phenomenon in OCR-treated patients with MS. The perception of wearing off is likely the result of natural fluctuations in MS symptoms and attribution bias.

Abstract
BACKGROUND AND OBJECTIVE Migraine is a neurological disorder characterized by episodes of moderate-to-severe headache. The emergence of drugs derived from monoclonal antibodies specific for the calcitonin gene has brought forth a therapeutic option for patients in whom the traditional treatments have failed. This study aimed to evaluate the clinical effectiveness of calcitonin gene-related peptide antibodies in the prevention of migraine through a systematic review and meta-analysis of observational cohort studies. METHODS A literature search for evidence was performed in electronic databases for observational studies that evaluated adult patients with migraine receiving calcitonin gene-related peptide receptor antagonists (e.g. erenumab, fremanezumab, galcanezumab and eptinezumab) and reported effectiveness outcomes (mean reduction in monthly migraine/headache days, and proportion of patients with 50% or greater reduction in migraine/headache days). RESULTS During the screening process, 47 records were included for data extraction and qualitative and quantitative analyses. The overall rate of patients with a reduction of at least 50% of mean monthly migraine days was 54% (95% CI 49-59%), and overall mean monthly migraine reduction was about 7.7 days (95% CI 8.4-7.0 days). Regarding the outcome ≥ 50% reduction in mean monthly headache reduction, the overall rate of patients with a reduction of at least 50% was 57% (95% CI 48-64%), and the overall mean monthly headache reduction was approximately 8.8 days (95% CI 10.1-7.5 days). Subgroup analyses considering the drug treatment used and type of migraine were consistent with previous results. CONCLUSIONS The use of calcitonin gene-related peptide antibodies in real-world studies to prevent migraine demonstrates promising effectiveness outcomes, in agreement with those reported in previously published randomized clinical trial reports.

Abstract
Migraine preventive treatment with the CGRP-receptor monoclonal antibody Erenumab can positively impact health-related quality of life (HRQoL) and disease-associated disability. Patient-reported outcome measures (PROMs) are a valuable additional datapoint to real-world evidence covering how treatment affects physical, mental, and social domains of patients' lives. In this real-world, single-center retrospective observational cohort study, we analyzed clinical performance indicators and PROMs for migraine patients who failed at least four other preventive medications and received Erenumab over the course of one year. Endpoints were the average monthly migraine days as well as PROMs including the MIDAS, EQ-5D-VAS and PROMIS-29. Data were collected digitally via the software heartbeat ONE in an ambulatory care setting as part of the clinical routine. A total of 145 patients treated with Erenumab provided data for 12 months. After 12 months, the median number of monthly migraine days decreased from 9 to 7 days. A clinically relevant reduction in migraine days by ≥30% was reported by 40% of the patients. The migraine-specific MIDAS score, the EQ-5D-VAS measuring the overall health status and all PROMIS domains, except sleep disturbance, changed significantly, reflecting a positive disease progression. This study highlights how patients with a treatment-resistant migraine in an outpatient setting benefit from a preventive treatment with Erenumab. A decrease in migraine days and an increase in HRQoL was maintained over one year. It also underscores the significance of collecting real-world evidence, including PROMs, as an integral component of the healthcare cycle, as such data can reveal additional factors relevant to treatment.

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

Bagherzadeh-Fard M, Amin Yazdanifar M, Sadeghalvad M, Rezaei N. Erenumab efficacy in migraine headache prophylaxis: A systematic review. Int Immunopharmacol 2023; 117:109366. [PMID: 37012858 DOI: 10.1016/j.intimp.2022.109366] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2022] [Revised: 09/25/2022] [Accepted: 10/15/2022] [Indexed: 03/11/2023]
Abstract
OBJECTIVE This systematic review aims to show the efficiency of Erenumab in the preventive therapy of episodic and chronic migraine, which is still under research. BACKGROUND Migraine is a chronic neurovascular disorder that causes disability and a social burden. There are various medications used for migraine prevention regimens, most of which have unwanted side effects and aren't often quite effective. Erenumab is a monoclonal antibody that targets calcitonin gene-related peptide receptors and was recently approved by the Food and Drug Administration for migraine prevention. METHODS For this systematic review, we searched through Scopus and PubMed databases using "Erenumab" or "AMG 334" and "migraine" as keywords, and all the studies from 2016 to March 18, 2022, were included. Original English articles assessing any outcomes referring to the efficacy of Erenumab in migraine headache treatment were included in this study. RESULTS We found 53 out of 605 papers eligible to be investigated. Erenumab in both dosages of 70 mg and 140 mg could decrease the mean of monthly migraine days and monthly acute migraine-specific medication days. Erenumab also has a higher rate of ≥ 50 %, ≥ 75 %, and 100 % reduction in monthly migraine days from the baseline in different regions. The efficacy of Erenumab was initiated in the first week of administration and sustained throughout and after treatment. Erenumab was also potent in the treatment of migraine with allodynia, aura, prior preventive therapy failure, medication overuse headache, and menstrual migraine. Erenumab also had favorable outcomes in combination therapy with other preventive drugs like Onabotulinumtoxin-A. CONCLUSION Erenumab had remarkable efficacy in the short and long-term treatment of episodic and chronic migraine, notably the patients with difficult-to-treat migraine headaches.

Abstract
BACKGROUND A new migraine prevention, CGRP monoclonal antibodies (mAbs), is injectable on a monthly or quarterly basis. In clinical practice, some patients reported that drug effectiveness does not last until the upcoming scheduled injection, a so-called "wearing-off" effect. We aimed to evaluate the wearing-off effect of the CGRP mAbs for migraine prevention in patients with different monthly migraine days. METHODS We conducted a literature search for studies that reported migraine frequency after CGRP monoclonal antibody administration from MEDLINE, SCOPUS, Web of Science, and Cochrane Database from inception through February 2022. A meta-analysis, random-effects model was applied to assess the difference in migraine frequency between early and later weeks after medication to assess the presence of a wearing-off effect. Risk ratio was calculated to report the pooled treatment effect. RESULTS Four studies were entered for the analysis, comprising 2409 patients in randomized controlled trials. There was no association between CGRP mAbs and wearing-off effect in patients with galcanezumab with a pooled risk ratio of 1.29 (95% CI 0.73 to 2.28) compared to placebo group. However, there was an association between galcanezumab and wearing-off effect in patients with chronic migraine with a pooled risk ratio of 1.91 (95% CI 1.11 to 3.28) compared to placebo group. CONCLUSION In this meta-analysis, there was a wearing-off efficacy of galcanezumab but only in a small percentage of patients with chronic migraine in randomized controlled trials.

Abstract
Calcitonin gene-related peptide (CGRP) is a neuropeptide with diverse physiological functions. Its two isoforms (α and β) are widely expressed throughout the body in sensory neurons as well as in other cell types, such as motor neurons and neuroendocrine cells. CGRP acts via at least two G protein-coupled receptors that form unusual complexes with receptor activity-modifying proteins. These are the CGRP receptor and the AMY1 receptor; in rodents, additional receptors come into play. Although CGRP is known to produce many effects, the precise molecular identity of the receptor(s) that mediates CGRP effects is seldom clear. Despite the many enigmas still in CGRP biology, therapeutics that target the CGRP axis to treat or prevent migraine are a bench-to-bedside success story. This review provides a contextual background on the regulation and sites of CGRP expression and CGRP receptor pharmacology. The physiological actions of CGRP in the nervous system are discussed, along with updates on CGRP actions in the cardiovascular, pulmonary, gastrointestinal, immune, hematopoietic, and reproductive systems and metabolic effects of CGRP in muscle and adipose tissues. We cover how CGRP in these systems is associated with disease states, most notably migraine. In this context, we discuss how CGRP actions in both the peripheral and central nervous systems provide a basis for therapeutic targeting of CGRP in migraine. Finally, we highlight potentially fertile ground for the development of additional therapeutics and combinatorial strategies that could be designed to modulate CGRP signaling for migraine and other diseases.

Observational Analysis of the Costs Associated with Acute Treatment of Breakthrough Migraine Attacks in Medicaid Patients Using Preventive Therapies. Adv Ther 2023; 40:1141-1152. [PMID: 36648736 PMCID: PMC9988741 DOI: 10.1007/s12325-022-02386-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/21/2022] [Indexed: 01/18/2023]
Abstract
INTRODUCTION Medications for preventive treatment of migraine reduce migraine frequency, usually measured by a reduction in monthly migraine days (MMD), but generally do not eliminate the need for acute treatment. To assess the economic impact of treatment-related reductions in frequency, methodological guidance recommends capturing cost differences along the spectrum of MMD. OBJECTIVE Characterize monthly migraine medication costs along the spectrum of MMD for patients using calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAbs) for prevention. METHODS Medicaid State Drug Utilization Data (SDUD) were used to identify formulations and per-unit costs for oral, intranasal, and parenteral migraine-specific medications for acute and preventive treatment used by fee-for-service (FFS) Medicaid enrollees in 2020. National drug codes of relevant therapies were used to match SDUD to formulation characteristics including substance, route of administration, and branded/generic marketing status. Mean per-unit cost and the formulation's share of total prescriptions were estimated. Monthly medication costs were modeled based on formulations' per-unit costs and frequency of acute medication use during clinical trials of CGRP mAbs. RESULTS In the SDUD, there were 563,338 prescriptions for migraine-specific acute medications; triptans accounted for 97.37%. Triptan formulations prescribed were 83.78% oral tablet, 10.89% orally disintegrating tablet, 2.60% intranasal, and 2.73% parenteral. Dihydroergotamine accounted for < 1% of total prescriptions and had the highest per-unit cost ($443.50, branded intranasal). There were 97,119 prescriptions for CGRP mAbs, the majority for erenumab (45.73%) or galcanezumab (45.24%). Modeled monthly acute and preventive medication costs ranged from approximately $550 in patients with the fewest MMD treated with oral triptans to > $1500 in patients with the most MMD treated with dihydroergotamine. CONCLUSION In consideration of the migraine-specific acute medications used in FFS Medicaid 2020, for patients using CGRP mAbs for prevention, medication costs may vary significantly with the number of breakthrough attacks treated per month and the type of migraine-specific acute therapy used.

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
INTRODUCTION Migraine prophylactic therapy has changed over recent years with the development and approval of monoclonal antibodies (mAbs) targeting the calcitonin gene-related peptide (CGRP) pathway. As new therapies emerged, leading headache societies have been providing guidelines on the initiation and escalation of such therapies. However, there is a lack of robust evidence looking at the duration of successful prophylaxis and the effects of therapy discontinuation. In this narrative review we explore both the biological and clinical rationale for prophylactic therapy discontinuation to provide a basis for clinical decision-making. METHODS Three different literature search strategies were conducted for this narrative review. These include i) stopping rules in comorbidities of migraine in which overlapping preventives are prescribed, notably depression and epilepsy; ii) stopping rules of oral treatment and botox; iii) stopping rules of antibodies targeting the CGRP (receptor). Keywords were utilized in the following databases: Embase, Medline ALL, Web of Science Core collection, Cochran Central Register of Controlled Trials, and Google Scholar. DISCUSSION Reasons to guide decision-making in stopping prophylactic migraine therapies include adverse events, efficacy failure, drug holiday following long-term administration, and patient-specific reasons. Certain guidelines contain both positive and negative stopping rules. Following withdrawal of migraine prophylaxis, migraine burden may return to pre-treatment level, remain unchanged, or lie somewhere in-between. The current suggestion to discontinue CGRP(-receptor) targeted mAbs after 6 to 12 months is based on expert opinion, as opposed to robust scientific evidence. Current guidelines advise the clinician to assess the success of CGRP(-receptor) targeted mAbs after three months. Based on excellent tolerability data and the absence of scientific data, we propose if no other reasons apply, to stop the use of mAbs when the number of migraine days decreases to four or fewer migraine days per month. There is a higher likelihood of developing side effects with oral migraine preventatives, and so we suggest stopping these drugs according to the national guidelines if they are well tolerated. CONCLUSION Translational and basic studies are warranted to investigate the long-term effects of a preventive drug after its discontinuation, starting from what is known about the biology of migraine. In addition, observational studies and, eventually, clinical trials focusing on the effect of discontinuation of migraine prophylactic therapies, are essential to substantiate evidence-based recommendations on stopping rules for both oral preventives and CGRP(-receptor) targeted therapies in migraine.

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
OBJECTIVE To assess long-term safety, tolerability, and efficacy of once-daily oral atogepant 60 mg in adults with migraine. BACKGROUND Atogepant is an oral, small-molecule, calcitonin gene-related peptide receptor antagonist approved for the preventive treatment of episodic migraine. METHODS A 52-week, multicenter, randomized, open-label trial of adults (18-80 years) with migraine. Lead-in trial completers or newly enrolled participants with 4-14 migraine days/month were enrolled and randomized (5:2) to atogepant 60 mg once daily or oral standard care (SC) migraine preventive medication. The primary objective was to evaluate the safety and tolerability of atogepant; safety assessments included treatment-emergent adverse events (TEAEs), clinical laboratory evaluations, vital signs, and Columbia-Suicide Severity Rating Scale scores. Efficacy assessments (atogepant only) included change from baseline in mean monthly migraine days (MMDs) and the proportion of participants with reductions from baseline of ≥50%, ≥75%, and 100% in MMDs. RESULTS The trial included 744 participants randomized to atogepant 60 mg (n = 546) or SC (n = 198). The atogepant safety population was 88.2% female (n = 479/543) with a mean (standard deviation) age of 42.5 (12.0) years. TEAEs occurred in 67.0% (n = 364/543) of participants treated with atogepant 60 mg. The most commonly reported TEAEs (≥5%) were upper respiratory tract infection (10.3%; 56/543), constipation (7.2%; 39/543), nausea (6.3%; 34/543), and urinary tract infection (5.2%; 28/543). Serious TEAEs were reported in 4.4% (24/543) for atogepant. Mean (standard error) change in MMDs for atogepant was -3.8 (0.1) for weeks 1-4 and -5.2 (0.2) at weeks 49-52. Similarly, the proportion of participants with ≥50%, ≥75%, and 100% reductions in MMDs increased from 60.4% (310/513), 37.2% (191/513), and 20.7% (106/513) at weeks 1-4 to 84.2% (282/335), 69.9% (234/335), and 48.4% (162/335), at weeks 49-52. CONCLUSION Daily use of oral atogepant 60 mg for preventive treatment of migraine during this 1-year, open-label trial was safe, well tolerated, and efficacious.

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
BACKGROUND Acupuncture is used to treat subjects with occipital neuralgia, which is 1 of the main causes of occipital pain; however, its effect is conflicting. Hence, the current study aims to evaluate the effects of acupuncture in the treatment of occipital neuralgia. METHODS In a systematic search of PubMed, Embase, OVID, China National Knowledge Infrastructure, Cochrane Library, Chinese Biomedical Literature Database, Wanfang databases, and Google Scholar until July 2021, 15 studies aimed to evaluate the effects of acupuncture in the treatment of occipital neuralgia were included. Human-related trials were considered in different languages. The size of the study was not considered a limit for its inclusion and the study intervention should focus on comparing the impact of acupuncture in the intervention group compared with the control group.The odds ratio (OR) and the mean difference (MD) with 95% confidence intervals (CIs) were calculated with a random or fixed-effect model for different subgroup analyses. Publication bias was assessed using the Egger test, while the risk of bias was assessed using the Review manager software. RESULTS Acupuncture had a significantly higher effective rate of treatment (OR, 5.40; 95% CI, 2.48 to 11.77, P < .001) compared to control in the treatment of occipital neuralgia and lower visual analogue scale (MD, -2.45; 95% CI, -2.69 to -2.21, P < .001). Acupuncture plus medication had a significantly higher effective rate of treatment (OR, 3.96; 95% CI, 2.10 to 7.47, P < .001) compared to medication in the treatment of occipital neuralgia. Acupuncture analysis for safety issues showed a significant reduction of adverse events compared with the medication group. CONCLUSION Acupuncture alone or acupuncture plus medication had a significantly beneficial effect on the effective rate of treatment, safety and visual analog scale compared to medication in the treatment of occipital neuralgia. Further studies are required to validate these findings.

Abstract
Background Calcitonin gene-related peptide (CGRP) inhibitors have been developed as options for treatment of chronic and episodic migraine. We present our experience of the use of erenumab in a tertiary headache centre. Methods This was a prospective clinical audit of all patients commenced on erenumab following a locally agreed pathway and criteria over a consecutive period. Patients received monthly erenumab 140 mg for 3 months. Data were collected prospectively at baseline and 3 months follow up. Results One hundred three patients were commenced on erenumab during the study period. Patients had tried a median of 7 previous prophylactics, including onabotulinum toxin A in 94%. At 3 months there was a reduction in median total (28 to 20, 29% reduction, p < 0.0001) and severe (15 to 5, 67% reduction, p < 0.0001) headache days. 39.8% of patients achieved at least a 30% reduction in total headache days; 61.8% of patients achieved at least a 50% reduction in severe headache days. Meeting either of these thresholds was considered a positive response, 68% of patients achieved this. Presence of daily headache pattern was negatively associated with response, (56% response vs. 90% without daily headache, p = 0.0003). There was no association between age, gender, presence of medication overuse or number of previously tried prophylactic treatments and response to erenumab. 43% of patients reported at least one adverse effect, most commonly constipation (26%); treatment was discontinued in 3 patients due to adverse effects. Conclusions Erenumab was an effective treatment for chronic migraine in this treatment resistant population over 3 months of follow up. Presence of daily headache predicted poorer response but there was still a significant positive response rate in this group.

[PMID: 36047857 PMCID: PMC9826196 DOI: 10.1111/head.14386] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Revised: 06/29/2022] [Accepted: 06/30/2022] [Indexed: 01/11/2023]
Abstract
OBJECTIVE The objective of this study was to explore patient preference for attributes of calcitonin gene-related peptide (CGRP) inhibitors for the preventive treatment of migraine and to describe differences in treatment preferences between patients. BACKGROUND CGRP inhibitors are a novel class of migraine drugs specifically developed for the preventive treatment of migraine. Clinicians should understand patient preferences for CGRP inhibitors to inform and support prescribing choices. METHODS Patients with migraine in the US and Germany were recruited to participate in an online discrete choice experiment (DCE) survey, which presented hypothetical treatment choices using five attributes: mode of administration, side effects, migraine frequency, migraine severity, and consistency of treatment effectiveness. Attribute selection was informed by a literature review and semi-structured patient interviews (n = 35), and evaluated using patient cognitive debriefing interviews (n = 5). RESULTS Of 680 who consented to participate, 506 participants completed the survey and were included in the study (US = 257; Germany = 249). Overall, participants placed highest importance (preference weight, beta = 1.65, p < 0.001) on the treatment's ability to reduce the severity of migraine (mild vs. unchanged severity), followed by consistent treatment effectiveness (beta = 1.13, p < 0.001), and higher chance of reduced migraine frequency (beta = 1.00, p < 0.001). Participants preferred an oral tablet every other day (beta = 1.00, p < 0.001) over quarterly infusion, quarterly injections (p = 0.019), or monthly injection (p < 0.001). Preference for all treatment attributes were heterogeneous, and the subgroup analyses found that participants naïve to CGRP monoclonal antibody treatments had a stronger preference for oral therapy compared to those with such experience (p = 0.006). CONCLUSION In this DCE assessing CGRP inhibitors attributes, the main driver of patient choice was treatment effectiveness, specifically reduced migraine severity, and consistent treatment effectiveness. Further, patients exhibited an overall preference for an oral tablet every other day over injectables. Patients' experience with previous treatments informs the value they place on treatment characteristics.

Abstract
PURPOSE OF REVIEW To summarize available calcitonin gene-related peptide (CGRP)-targeting therapies for migraine and discuss their use in real-world populations. BACKGROUND CGRP has long been a topic of interest in migraine pathophysiology, with new therapies targeting CGRP since 2018 for both the preventive and acute treatment of migraine. METHODS We searched PubMed using keywords including "migraine," "CGRP," "real-world," "erenumab," "galcanezumab," "fremanezumab," "eptinezumab," "ubrogepant," "rimegepant," and "atogepant." We reviewed all pertinent studies and summarized main findings. We also compiled detailed patient characteristics (e.g., migraine diagnoses, medication overuse, prior treatment failures) and treatment outcome measures, such as 50% responder rates, reduction in migraine days, and adverse event rates in several tables. Overall, studies reporting real-world patient experiences of CGRP-targeting therapies suggested meaningful effectiveness for migraine treatment with response rates comparable to the numbers reported in clinical trials. Furthermore, studies suggested benefit in patients with multiple prior unsuccessful treatment trials, medication overuse, and complex medical comorbidities. In some studies, adverse event rates have been notably higher than reported in clinical trials. Additional long-term data is needed to further evaluate sustained efficacy, predictors of treatment response, and adverse events.

Abstract
BACKGROUND Previous research has extensively documented the impact of migraine episodes ('ictal') on patients' health-related quality of life. Few studies have looked at the impact of migraine on migraine-free days ('interictal'). This study was designed to describe interictal burden of migraine in a mixed group of people affected by migraine and to explore patient characteristics associated with interictal burden. METHODS People with migraine in the United States (US) and Germany were recruited for a cross-sectional online survey, including a subgroup treated with calcitonin gene-related peptide (CGRP) monoclonal antibody (mAb). The survey included the Migraine Interictal Burden Scale (MIBS-4), Headache Impact Test (HIT-6), and items measuring patient demographics, clinical and treatment background. Data were analyzed using descriptive statistics and linear regression. RESULTS Five hundred six people with migraine completed the survey (US: n = 257; Germany: n = 249), of whom 195 had taken a CGRP mAb for three or more months. Participants had a mean of 8.5 (SD = 6.4) Monthly Migraine Days (MMD) and 10.4 (SD = 7.1) Monthly Headache Days (MHD). The mean MIBS-4 score was 6.3 (SD = 3.4), with 67% reporting severe interictal burden (MIBS-4: ≥5). The mean HIT-6 score was 65.3 (SD = 6.0), with 86% reporting severe migraine impact (HIT-6: ≥60). MIBS-4 was correlated with the HIT-6 (r = 0.37), MMD and MHD (both r = 0.27). The HIT-6, MMD, MHD, CGRP mAb treatment, and depression all had an independent positive association with the MIBS-4. CONCLUSION Two-thirds of the study sample reported substantial interictal burden. Whilst interictal burden was associated with migraine frequency and impact of migraine attacks, study results also show it represented a distinct aspect of the overall disease burden. Study findings further indicate unique associations between interictal burden and depression. A unique positive association between interictal burden and CGRP mAb treatment suggests a remaining unmet need among people affected by migraine treated with CGRP mAb.

Abstract
Migraine is a highly disabling and often chronic neurological disease that affects more than one billion people globally. Preventive migraine treatment is recommended for individuals who have frequent and/or disabling attacks; however, many of the medications used for migraine prevention (e.g., antiepileptics, antidepressants, antihypertensives) were not specifically developed for migraine, and often have limited efficacy or poor tolerability. Four monoclonal antibodies targeting the calcitonin gene-related peptide (CGRP) pathway, which is believed to play a crucial role in the pathophysiology of migraine, have been approved by the US Food and Drug Administration for the preventive treatment of migraine in adults. All four migraine-specific treatments have demonstrated efficacy based on reductions in monthly days with migraine for patients with both episodic and chronic migraine, including those with comorbidities. They have also demonstrated favorable safety and tolerability profiles. Based on these accounts, CGRP pathway-targeted monoclonal antibodies have the potential to revolutionize preventive treatment for patients with migraine.

Abstract
BACKGROUND There is an unmet need for a better understanding and management of headache, particularly migraine, beyond specialist centers, which may be facilitated using digital technology. OBJECTIVE The objective of this study was to identify where, when, and how people with headache and migraine describe their symptoms and the nonpharmaceutical and medicinal treatments used as indicated on social media. METHODS Social media sources, including Twitter, web-based forums, blogs, YouTube, and review sites, were searched using a predefined search string related to headache and migraine. The real-time data from social media posts were collected retrospectively for a 1-year period from January 1, 2018, to December 31, 2018 (Japan), or a 2-year period from January 1, 2017, to December 31, 2018 (Germany and France). The data were analyzed after collection, using content analysis and audience profiling. RESULTS A total of 3,509,828 social media posts related to headache and migraine were obtained from Japan in 1 year and 146,257 and 306,787 posts from Germany and France, respectively, in 2 years. Among social media sites, Twitter was the most used platform across these countries. Japanese sufferers used specific terminology, such as "tension headaches" or "cluster headaches" (36%), whereas French sufferers even mentioned specific migraine types, such as ocular (7%) and aura (2%). The most detailed posts on headache or migraine were from Germany. The French sufferers explicitly mentioned "headache or migraine attacks" in the "evening (41%) or morning (38%)," whereas Japanese mentioned "morning (48%) or night (27%)" and German sufferers mentioned "evening (22%) or night (41%)." The use of "generic terms" such as medicine, tablet, and pill were prevalent. The most discussed drugs were ibuprofen and naproxen combination (43%) in Japan; ibuprofen (29%) in Germany; and acetylsalicylic acid, paracetamol, and caffeine combination (75%) in France. The top 3 nonpharmaceutical treatments are hydration, caffeinated beverages, and relaxation methods. Of the sufferers, 44% were between 18 and 24 years of age. CONCLUSIONS In this digital era, social media listening studies present an opportunity to provide unguided, self-reported, sufferers' perceptions in the real world. The generation of social media evidence requires appropriate methodology to translate data into scientific information and relevant medical insights. This social media listening study showed country-specific differences in headache and migraine symptoms experienced and in the times of the day and treatments used. Furthermore, this study highlighted the prevalence of social media usage by younger sufferers compared to that by older sufferers.

Abstract
BACKGROUND Clinical trials have shown that erenumab is effective and well-tolerated for the preventive treatment of chronic migraine. To extend the results from clinical trials, we assessed the real-world efficacy and safety of erenumab in patients with chronic migraine from the outpatient clinic at the Danish Headache Center. METHODS A 52-week, single-center, prospective, observation study of erenumab in adults with chronic migraine who are eligible for treatment with monoclonal antibodies against CGRP or its receptor in Denmark. The primary outcome was defined as proportion of patients who achieved ≥ 30% reduction in monthly migraine days (MMDs) from baseline to weeks 9-12. RESULTS A total of 300 adult patients with chronic migraine were enrolled and received at least one dose of erenumab. At baseline, the mean (SD) number of monthly headache days was 23 ± 4.9 and mean number of MMDs was 16.8 ± 6.4. Of 300 enrolled patients, 273 (91.0%) patients completed 12 weeks of treatment, and 119 (39.7%) completed 52 weeks of treatment. The number of patients who achieved ≥ 30% reduction in MMDs from baseline to weeks 9-12 was 195 (71.4%) of 273 patients. Sustained ≥ 30% reduction in MMDs at all assessment periods throughout the 52-week treatment period was achieved by 102 (34%) of 300 patients. Adverse events occurred in 220 (73.3%) out of 300 patients. The most common adverse event was constipation. Treatment discontinuation due to lack of tolerability occurred in 41 (13.7%) patients. CONCLUSIONS Among adult patients with chronic migraine and previous failure of medications for migraine prevention, erenumab was found to be effective and well-tolerated.

Abstract
PURPOSE OF REVIEW Medication overuse headache (MOH) affects more than 60 million individuals worldwide causing enormous personal and social burden. Only repurposed drugs are available for MOH that share limited evidence for efficacy. The preclinical data suggesting that activation of the calcitonin gene-related peptide (CGRP) pathway is involved in headache chronification along with clinical evidence that monoclonal antibodies targeting CGRP (anti-CGRP mAbs) have good efficacy in preventing chronic migraine, triggered this review that aims to summarize the current data on the effectiveness and safety of mAbs against CGRP in MOH. RECENT FINDINGS Post hoc analyses of phase-3 trials of erenumab, fremanezumab, galcanezumab, and eptinezumab for the prevention of chronic migraine revealed that patients with MOH benefit from the treatment over placebo. Several real-world studies confirm the efficacy of erenumab and galcanezumab in patients with MO. However, all published trials evaluated treatments in patients with chronic migraine with MO collectively, not in patients with MOH exclusively. SUMMARY The available data indicate that anti-CGRP mAbs represent a good mechanism-based and disease-specific therapeutical option with for MOH as long as detoxification and additional nonpharmaceutical interventions are operated. Future research should focus on long-term-controlled trials in MOH populations exclusively.

Abstract
BACKGROUND Migraine is a highly disabling and prevalent neurological disorder. A peptide, calcitonin gene-related peptide, was identified as involved in migraine pathophysiology and monoclonal anti-CGRP antibodies have been developed. AIM To describe the clinical characteristics and therapeutic response of migraine patients treated with monoclonal antibodies. METHOD An observational, prospective, uncontrolled and descriptive study was carried out with a sample of 112 consecutive patients with episodic or chronic migraine treated with monoclonal antibodies. Eight patients did not return for the following medical consultation. They were excluded from the study. RESULTS A total of 104 patients were described. There was a predominance of episodic migraine. Before treatment, the average frequency of headache was 15.3±8.5 days per month, during the previous three months. Monoclonal antibodies were prescribed at the following frequency: erenumab (49%), galcanezumab (45.2%), and fremanezumab (5.8%). After the third month, the reduction in headache attacks was greater than 50% in 57.7% of patients. Adverse events were referred by 18.3% of patients, in this order of frequency: constipation (7.7%), insomnia (2.9%), vertigo (1.9%), erythema at the injection site (1.9%), arthralgia (1%), nasopharyngitis (1%), facial and hand edema (1%), irritation at the injection site (1%), and paresthesia at the injection site (1%). CONCLUSIONS This described analysis of migraine patients who used monoclonal antibodies presented one of the first Brazilian experiences with real-world patients. Our results may enlighten clinicians on the outcomes and ways of prescribing anti-CGRP antibodies.

Abstract
Background Fremanezumab, a fully humanized monoclonal antibody (mAb; IgG2Δa) that selectively targets calcitonin gene-related peptide (CGRP), is approved for the preventive treatment of migraine in adults. The efficacy and safety of fremanezumab for migraine prevention have been demonstrated in randomized, double-blind, placebo-controlled trials. Real-world effectiveness data are needed to complement clinical trial data. This study assessed the effectiveness of fremanezumab across different subgroups of adult patients with episodic migraine (EM), chronic migraine (CM), or difficult-to-treat (DTT) migraine in real-world clinical settings. Methods This retrospective, panel-based online chart review used electronic case report forms. Patient inclusion criteria were a physician diagnosis of EM or CM; age ≥ 18 years at the time of first fremanezumab initiation; ≥ 1 dose of fremanezumab treatment; ≥ 1 follow-up visit since first initiation; and ≥ 2 measurements of monthly migraine days (MMD; with 1 within a month before or at first initiation and ≥ 1 after first initiation). Changes in MMD and monthly headache days were assessed during the follow-up period. These endpoints were evaluated in subgroups of patients by migraine type (EM/CM) and in subgroups with DTT migraine (diagnosis of medication overuse [MO], major depressive disorder [MDD], generalized anxiety disorder [GAD], or prior exposure to a different CGRP pathway–targeted mAb [CGRP mAb]). Results Data were collected from 421 clinicians and 1003 patients. Mean (percent) reductions from baseline in MMD at Month 6 were − 7.7 (77.0%) in EM patients, − 10.1 (68.7%) in CM patients, − 10.8 (80.6%) in the MO subgroup, − 9.9 (68.3%) in the MDD subgroup, − 9.5 (66.4%) in the GAD subgroup, and − 9.0 (68.7%) in the prior CGRP mAb exposure subgroup. Improvements in MDD or GAD severity were reported by 45.5% and 45.8% of patients with comorbid MDD or GAD, respectively. Conclusions In this real-world study, fremanezumab demonstrated effectiveness for migraine regardless of migraine type or the presence of factors contributing to DTT migraine (MO, GAD, MDD, or prior exposure to a different CGRP mAb).

Abstract
Calcitonin gene-related peptide (CGRP), a 37 amino-acid neuropeptide found mostly in peptidergic sensory C-fibers, has been suggested to be implicated in the pathogenesis of migraine, which is one of the most common neurological disorders seen in medical practice, affecting almost 16% of the US population. While previously thought to be a vascular condition, migraine attacks are the result of neurogenic inflammation and peripheral/central sensitization through dysfunctional activation of the trigeminovascular system. To date, two classes of therapeutic agents have been developed to interrupt the function of CGRP: CGRP-targeted monoclonal antibodies (mAbs) and small-molecule antagonists (gepants). There are currently four CGRP-targeted mAbs and three gepants that are US Food and Drug Administration (FDA) approved for the treatment of migraine. Multiple phase II and III studies have established the efficacies and tolerability of these treatments. Previously, we reviewed the fundamental role of CGRP in migraine pathogenesis. Here, we discuss in depth the clinical evidence (randomized controlled trials and real-world studies), safety, and tolerability of CGRP-targeted mAbs and gepants for treating migraine.

Abstract
BACKGROUND Despite development of new therapies, migraine remains an undertreated illness. It is important to understand patients' preferences and perceptions of using a certain therapy. We present data from a nationwide Lithuanian survey of patients' experience using erenumab for the treatment of high frequency episodic and chronic migraine. METHODS An anonymous internet survey was distributed on February-March 2021 to the members of Migraine Association of Lithuania. All adult respondents who reported using at least one dose of erenumab were included in the study. RESULTS Out of 145 respondents, 75.2% had chronic migraine, and 31.7% had medication overuse headache. Patients received an average of 6 (IQR 4-9) erenumab doses. 93.1% respondents found erenumab effective, and 72.6% experienced improvement during the first month. MHDs were reduced by 9.8 (SD 6.0) (P < 0.001), and MMDs by 7.2 (SD 5.2) days (P < 0.001). 78.6% respondents achieved ≥ 50% reduction and 47.6% achieved ≥ 75% reduction of MMDs. 13.8% patients indicated a wearing-off effect during the treatment course, and 37.8% - some wearing-off between injections. Constipation was the most frequent adverse event (32.6%). 47.2% of patients who had a positive erenumab effect and discontinued treatment experienced migraine rebound in 6 (SD 2.0) weeks. CONCLUSION Erenumab is perceived as an effective and safe treatment. Further studies are needed to investigate a post-cessation deterioration of achieved improvement. HIGHLIGHTS • Vast majority of patients experience stable or increasing effect of erenumab. • Erenumab efficacy usually becomes evident during the first month of treatment. • Erenumab is perceived significantly better than non-specific preventive medications. • Almost 40% of patients experienced some wearing-off between injections. • Almost half of patients experience migraine rebounds after treatment cessation.

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
Background The efficacy and tolerability of fremanezumab, a fully humanized monoclonal antibody (IgG2Δa) that selectively targets calcitonin gene-related peptide (CGRP) and is approved for the preventive treatment of migraine in adults, have been demonstrated in randomized, double-blind, placebo-controlled trials. Real-world data can further support those clinical trial data and demonstrate the full clinical benefits of fremanezumab. This chart review assessed the effectiveness of fremanezumab for improving clinical outcomes in adult patients with migraine treated according to real-world clinical practice. Methods This retrospective, panel-based, online physician chart review study used electronic case report forms with US physicians. Patient inclusion criteria were a physician diagnosis of migraine, fremanezumab treatment initiation at ≥ 18 years of age after US Food and Drug Administration approval, ≥ 1 dose of fremanezumab treatment, and ≥ 2 assessments of monthly migraine days (MMD; 1 within 30 days before treatment initiation and ≥ 1 after initiation). Changes from baseline in MMD, monthly headache days (MHD), and Migraine Disability Assessment (MIDAS) and 6-item Headache Impact Test (HIT-6) scores were assessed over 6 months. These endpoints were evaluated in the overall population and subgroups divided by dosing schedule and number of prior migraine preventive treatment failures. Results This study included data from 421 clinicians and 1003 patients. Mean age at fremanezumab initiation was 39.7 years, and most patients were female (75.8%). In the overall population, mean baseline MMD and MHD were 12.7 and 14.0, respectively. Mean (percent) reductions from baseline in MMD and MHD, respectively, were − 4.6 (36.2%) and − 4.7 (33.6%) at Month 1, − 6.7 (52.8%) and − 6.8 (48.6%) at Month 3, and − 9.2 (72.4%) and − 9.8 (70.0%) at Month 6. Mean (percent) reductions from baseline in MIDAS and HIT-6 scores also increased over the 6-month study period, from − 6.2 (21.6%) and − 8.4 (14.0%) at Month 1 to − 18.1 (63.1%) and − 16.2 (27.0%) at Month 6, respectively. Improvements in these outcomes over 6 months were observed across all evaluated subgroups. Conclusions This real-world study demonstrated effectiveness of fremanezumab treatment for up to 6 months, irrespective of dosing regimen or number of prior migraine preventive treatment failures, reflecting ongoing, clinically meaningful improvements in patient outcomes.

Abstract
Erenumab is a monoclonal antibody targeting the calcitonin gene-related peptide (CGRP) receptor suitable for episodic and chronic migraine prevention. Randomized clinical trials proved the superiority of erenumab to placebo in a strictly selected population, while real-world studies confirmed treatment efficacy in more severe forms of disease – most patients suffered from chronic migraine with medication overuse headache, had prior treatment failures, and long disease duration. According to guidelines, anti-CGRP pathway monoclonal antibodies should be reserved to patients who failed or have contraindication to several classes of preventive treatments. However, their ease of use, tolerability and efficacy make these monoclonal antibodies ideally suitable for most patients with migraine; cost-effectiveness needs to be considered when looking at expanding current prescription criteria. Also, data from open label extensions of randomized control trials confirmed sustained benefits of prolonged treatment up to 5 consecutive years without significant risk of adverse events. Further studies will provide insights on optimal treatment duration to achieve migraine remission and predictors of treatment response. In the present work, we aimed at reviewing design and results of the main studies on erenumab and discussing treatment use in the current migraine prevention scenario; we also summarized the main ongoing research projects and provided clinical perspectives for the future.

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
Background Migraine frequency increases after the cessation of successful preventive treatment with CGRP(-receptor) monoclonal antibodies (mAbs). In this study, we aimed to evaluate the course of migraine after treatment resumption. Methods Patients with migraine, who started treatment with the same CGRP(-R) mAb after a three-month drug holiday were included in this analysis. We collected headache data at four prospective visits: 1) during the four weeks before the initial mAb treatment (baseline); 2) during the four weeks before the last mAb injection; 3) in weeks 13–16 of the drug holiday; 4) in weeks 9–12 after treatment restart. Outcomes were the changes in monthly migraine days (MMD), monthly headache days (MHD), monthly days with acute medication use (AMD) and Headache Impact Test-6 (HIT-6) scores across the observation period. Results This study included 39 patients (erenumab n = 16; galcanezumab/ fremanezumab n = 23). MMD decreased from 12.3 ± 6.3 at the end of the drug holiday to 7.8 ± 5.5 three months after treatment restart (p = 0.001). The improvement after treatment resumption was similar to the response in the initial treatment period (baseline: 12.3 ± 6.3 MMD vs. 7.5 ± 5.2 MMD before treatment interruption). MHD and AMD showed a significant improvement after treatment restart. HIT-6 scores decreased, indicating a diminished impact of headache on everyday life. Conclusions Reinitiation of treatment with CGRP(-R) mAbs after a drug holiday leads to a significant reduction of migraine frequency and medication use as well as improvement in quality of life.

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
WHAT IS KNOWN AND OBJECTIVE?: Erenumab and galcanezumab have shown great results for migraine prevention. However, strict inclusion criteria, absence of concomitant medication and selective outcome report of clinical trials may sometimes be barely representative of the real-world daily practice. Therefore, this study was designed to evaluate effectiveness and safety of these two monoclonal antibodies targeting calcitonin gene-related peptide in real-world patients. METHODS: This observational, retrospective study evaluated the effectiveness and safety of erenumab 140 mg and galcanezumab 120 mg in 142 real-world patients who had previously not responded to three well-established pharmacological alternatives for migraine prevention. To do so, a combination of objective parameters (monthly headache days and acute migraine-specific medication days) and subjective measurements (Migraine Disability Assessment questionnaire, Headache Impact Test and Visual Analogue Scale), validated for clinical research in migraine, were assessed during clinical interview. RESULTS AND DISCUSSION: Findings here reported show that erenumab and galcanezumab reduced monthly headache days, acute migraine specific medication days per month, Headache Impact Test score, Migraine Disability Assessment Test score and Visual Analogue Scale score after 3 and 6 doses (p < 0.01). Additionally, more than 25% of the patients enrolled in the study experienced a reduction by a half in monthly headache days, and more than 50% of the patients also reported a reduction by a half in the number of migraine specific medication days. Both treatments exhibited a great safety profile, rarely leading to discontinuation because of poor tolerance. WHAT IS NEW AND CONCLUSIONS?: Altogether, these results support previous real-life studies regarding effectiveness and safety and provide an interesting insight in how these preventive therapies are also effective in patients diagnosed with difficult to treat migraine who have previously failed, at least, three different drug classes stablished by current neurology guidelines for migraine prevention. Moreover, these data may suggest that erenumab and galcanezumab are able to not only diminish frequency, but also migraine intensity, and that it should be also considered as an effectiveness measure in line with other authors suggestion.

Ailani J, Kuruppu DK, Rettiganti M, Oakes T, Schroeder K, Wietecha L, Port M, Blumenfeld AM. Does “wearing off” of efficacy occur in galcanezumab‐treated patients at the end of the monthly treatment cycle? Post hoc analyses of four phase III randomized trials. Headache 2022; 62:198-207. [PMID: 35076090 PMCID: PMC9306502 DOI: 10.1111/head.14257] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Revised: 11/11/2021] [Accepted: 11/13/2021] [Indexed: 11/28/2022]
Abstract
Objective The purpose of this study was to propose a definition of “wearing off” at the individual patient‐level and determine the percentage of patients with migraine who experience “wearing off” of efficacy of galcanezumab at the end of a treatment cycle using this predefined threshold. Background Anecdotal reports suggest that some patients may experience “wearing off” of efficacy during the last week of their calcitonin gene‐related peptide monoclonal antibody treatment cycle. A previous post hoc analysis of galcanezumab demonstrated consistent efficacy at each week throughout all monthly dosing intervals at the population‐level, but “wearing off” has not been assessed at the individual patient‐level. Methods Post hoc analyses of clinical trial data from four galcanezumab phase III, randomized, placebo‐controlled studies in a total of 2680 patients with high‐frequency episodic migraine (EVOLVE‐1, EVOLVE‐2, and CONQUER studies) or chronic migraine (CM; REGAIN and CONQUER studies) were conducted. “Wearing off” was defined as an increase of greater than or equal to 2 weekly migraine headache days in the last week of the treatment cycle compared to the second week for at least 2 months. The analyses were conducted (1) in all patients and (2) in patients with a clinically meaningful response to treatment. Results The percentage of patients meeting the threshold of “wearing off” was not statistically significantly different among the placebo, galcanezumab 120 mg, and galcanezumab 240 mg treatment groups, both in the total population and in patients with a clinically meaningful response (all ≤9.0%). Although the frequency of “wearing off” in patients with CM and prior preventive failures was numerically greater in the galcanezumab groups (8/89 or 9.0%) compared to placebo (3/95 or 3.2%), these differences were not statistically significant. Conclusions Consistent with previous analyses at the population‐level that showed no evidence of decreased efficacy at the end of a treatment cycle, rates of individual patients meeting the threshold of “wearing off” in this analysis were low and similar among placebo, galcanezumab 120 mg, and galcanezumab 240 mg treatment groups.

Constipation Caused by Anti-calcitonin Gene-Related Peptide Migraine Therapeutics Explained by Antagonism of Calcitonin Gene-Related Peptide's Motor-Stimulating and Prosecretory Function in the Intestine. Front Physiol 2022; 12:820006.

Abstract
The development of small-molecule calcitonin gene-related peptide (CGRP) receptor antagonists (gepants) and of monoclonal antibodies targeting the CGRP system has been a major advance in the management of migraine. In the randomized controlled trials before regulatory approval, the safety of these anti-CGRP migraine therapeutics was considered favorable and to stay within the expected profile. Post-approval real-world surveys reveal, however, constipation to be a major adverse event which may affect more than 50% of patients treated with erenumab (an antibody targeting the CGRP receptor), fremanezumab or galcanezumab (antibodies targeting CGRP). In this review article we address the question whether constipation caused by inhibition of CGRP signaling can be mechanistically deduced from the known pharmacological actions and pathophysiological implications of CGRP in the digestive tract. CGRP in the gut is expressed by two distinct neuronal populations: extrinsic primary afferent nerve fibers and distinct neurons of the intrinsic enteric nervous system. In particular, CGRP is a major messenger of enteric sensory neurons which in response to mucosal stimulation activate both ascending excitatory and descending inhibitory neuronal pathways that enable propulsive (peristaltic) motor activity to take place. In addition, CGRP is able to stimulate ion and water secretion into the intestinal lumen. The motor-stimulating and prosecretory actions of CGRP combine in accelerating intestinal transit, an activity profile that has been confirmed by the ability of CGRP to induce diarrhea in mice, dogs and humans. We therefore conclude that the constipation elicited by antibodies targeting CGRP or its receptor results from interference with the physiological function of CGRP in the small and large intestine in which it contributes to the maintenance of peristaltic motor activity, ion and water secretion and intestinal transit.
