Front Neurol 2024; 15:1402569. [PMID: 38938785 PMCID: PMC11210524 DOI: 10.3389/fneur.2024.1402569] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2024] [Accepted: 05/27/2024] [Indexed: 06/29/2024] Open
Abstract
Migraine, a prevalent neurological disorder, affects approximately 14.1% of the global population and disproportionately impacts females. This debilitating condition significantly compromises quality of life, productivity, and incurs high healthcare costs, presenting a challenge not only to individuals but to societal structures as a whole. Despite advances in our understanding of migraine pathophysiology, treatment options remain limited, necessitating ongoing research into effective therapies. This review delves into the complexity of migraine management, examining the roles of genetic predisposition, environmental influences, personalized treatment approaches, comorbidities, efficacy and safety of existing acute and preventive treatments. It further explores the continuum between migraine and tension-type headaches and discusses the intricacies of treating various migraine subtypes, including those with and without aura. We emphasize the recent paradigm shift toward trigeminovascular activation and the release of vasoactive substances, such as calcitonin gene-related peptide (CGRP), which offer novel therapeutic targets. We assess groundbreaking clinical trials, pharmacokinetic and pharmacodynamic perspectives, safety, tolerability, and the real-world application of CGRP monoclonal antibodies and gepants. In the face of persisting treatment barriers such as misdiagnosis, medication overuse headaches, and limited access to specialist care, we discuss innovative CGRP-targeted strategies, the high cost and scarcity of long-term efficacy data, and suggest comprehensive solutions tailored to Turkiye and developing countries. The review offers strategic recommendations including the formulation of primary care guidelines, establishment of specialized outpatient clinics, updating physicians on novel treatments, enhancing global accessibility to advanced therapies, and fostering patient education. Emphasizing the importance of lifestyle modifications and holistic approaches, the review underscores the potential of mass media and patient groups in disseminating critical health information and shaping the future of migraine management.

Abstract
INTRODUCTION The efficacy of galcanezumab has been demonstrated in randomized controlled trials, but evidence about its use under clinical practice conditions is still limited. This study aimed to describe the characteristics of the patients treated with galcanezumab in routine clinical practice in Spain as well as treatment patterns, persistence, and effectiveness. METHODS A retrospective chart review study was carried out in six hospitals. Information of adults with migraine, who started treatment with galcanezumab between November 2019 and September 2021, was analyzed until end or loss of follow-up. Continuous variables were described as mean (standard deviation, SD) and median (interquartile range, IQR), and categorical variables as frequency and percentages. Persistence to treatment was estimated using Kaplan-Meier analysis. RESULTS A total of 314 patients were analyzed over median follow-up period of 17.5 months (13.8-20.7), with a mean age of 46.3 (12.6), 85% women, 80.6% chronic migraine, and reporting a mean of monthly migraine days of 16.7 (7.8). Overall, 72.9% had comorbid conditions, with anxiety and depression disorders being the most frequent. More than 60% had received ≥ 6 previous preventive drugs, the most common being antiepileptics, antidepressants, and botulinum toxin (95.2%, 89.8% and 84.1%, respectively). Overall, 60.3% of the patients with other preventive treatments maintained them after galcanezumab initiation. The median time on galcanezumab was 14.6 months (9.4-22.8); 95.7%, 82.0%, 76.2% and 59.8% of patients were persistent to treatment at 3, 6, 9 and 12 months, respectively. Of the patients who discontinued (151: 48.1%), 57.6% were due to lack of effectiveness and 31.1% were due to improvement in migraine. The average reduction of monthly migraine days at 3, 6, 9 and 12 months was 7.9 (7.2), 9.1 (7.5), 8.8 (6.6) and 9.0 (6.9) days, respectively. CONCLUSIONS In real clinical practice, galcanezumab is an effective treatment and has a high persistence in patients with migraine, mostly chronic and with multiple use of previous preventive treatments.

Long-Term Effectiveness of Galcanezumab in the Prevention of Migraine: An Italian Retrospective Analysis (REALITY). Neurol Ther 2024; 13:415-435. [PMID: 38329615 PMCID: PMC10951161 DOI: 10.1007/s40120-024-00582-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Accepted: 01/15/2024] [Indexed: 02/09/2024] Open
Abstract
BACKGROUND Galcanezumab is approved in the European Union (EU) as migraine prophylaxis in adults with at least four migraine days per month. The aim of this retrospective observational study was to evaluate the long-term effectiveness of galcanezumab on migraine-related burdens and its impact on the use of healthcare resources for migraine prophylaxis in an Italian setting. METHODS This retrospective study was conducted in patients with migraine who initiated treatment with galcanezumab for migraine prevention between September 2019 and December 2020. Patient data for monthly migraine days (MMDs) and MMDs with acute medication intake were obtained by medical chart reviews. Information on patient-reported outcomes (using the Migraine Disability Assessment [MIDAS] questionnaire and Headache Impact Test 6 [HIT-6] questionnaire) and on the use of healthcare resources were also collected. The time points of interest were 1, 3, 6, 9, 12 months after the initiation of galcanezumab, and the most recent time point available during follow-up. RESULTS A total of 207 patients were enrolled in the study. Starting from month 3 after treatment initiation, more than half of the patients presented at least a 50% reduction in MMDs, and approximately one-third of non-responders at month 3 became responders at month 6. From month 3 to month 12, MMDs decreased on average by 10 days. Headache impact and disability, as well as migraine-associated health resource utilization decreased significantly during the treatment period. A positive significant association among the three dimensions of clinical burden (MMDs, MIDAS and days of acute medication intake) was also observed. CONCLUSION The results of this Italian real-world study confirmed that galcanezumab has a rapid onset of effect and provides a long-term response among patients over different migraine-related burdens. The use of healthcare resources was also remarkably reduced.

Abstract
Introduction Clinical trials show that calcitonin gene-related peptide monoclonal antibodies (CGRP mAbs) are effective preventative treatments for chronic migraine. Their efficacy over longer time periods and in cohorts originally excluded from trials remains uncertain. This study aims to explore the impact of CGRP mAbs in an Australian real-life setting. Methods A multicentre cohort study was performed in the tertiary headache clinics of the Alfred and Austin Hospitals, Melbourne, Australia. Patients were commenced on a CGRP mAb for chronic migraine and asked to keep a headache diary, recorded at 3 monthly appointments for 12 months. Primary outcome was a ≥50% reduction in monthly headache days (MHD). Results From a population of 105 patients, 90 patients commenced galcanezumab and 15 commenced fremanezumab. The ≥50% responder rate of the cohort was 52.4% after 3 months. Over 12 months follow-up, 25.7% of the cohort ceased due to a lack of efficacy and 16.2% ceased due to an adverse event. There was no difference in response or cessation between medications. There was poor agreement in 3-month and 12-month response rates (Cohen's κ=0.130; p=0.171). On subgroup analysis, continuous headache at baseline and number of trialled preventative treatments were the only factors associated with efficacy. Conclusion CGRP mAbs were associated with sustained reductions in MHD over 12-month follow-up in patients with resistant migraine in Australia. Further studies are required to determine treatment options for patients with continuous headache. Poor agreement between outcomes at 3 and 12 months highlights the need to assess some patients at later timepoints.

Abstract
BACKGROUND The complexity of clinical practice extends far beyond the controlled settings of trials, and there is a need for real-world studies aimed at identifying which patients will respond to anti-CGRP monoclonal antibodies in different countries. This study aimed to investigate the efficacy and safety of galcanezumab in treating migraine in a real-life setting in Turkey, as well as identify predictors of treatment response. METHODS A total of 476 patients who diagnosed with migraine according to ICHD-3 criteria and treated with galcanezumab by headache specialists were voluntarily participated in this cross-sectional study. Galcanezumab is indicated for the prevention of migraine in adults who have at least 4 monthly migraine days in Turkey. All patients filled out a survey on Google Form that comprised 54 questions, addressing various aspects such as demographics, migraine characteristics, previous use of acute symptomatic medication, failures with preventive drug classes, comorbidities, most bothersome symptoms, as well as the interictal burden of migraine. RESULTS Among the participants, 89.3% reported that galcanezumab treatment was beneficial for them. A decrease in the frequency (80.0%), severity (85.7%), and acute medication usage for migraine attacks (71.4%) was reported with galcanezumab treatment. An adverse effect related to galcanezumab was reported in 16.3% of cases, but no serious adverse reactions were observed. Remarkably, 14.3% of participants reported no longer experiencing any headaches, and 18.9% did not require any acute treatment while receiving galcanezumab treatment. A logistic regression model showed that male gender, lack of ictal nausea, and previous failure of more than 2 prophylactic agents may predict the non-responders. CONCLUSIONS The first large series from Turkey showed that galcanezumab treatment is safe and effective in most of the patients diagnosed with migraine by headache experts in the real-life setting. Patients reported a significant decrease in both ictal and interictal burden of migraine and expressed satisfaction with this treatment.

Abstract
OBJECTIVES Randomized controlled trials (RCTs) have established the efficacy of galcanezumab, an antibody binding calcitonin gene-related peptide (CGRP) ligand, in the preventive treatment of migraine. The objective was to summarize real-world data evaluating galcanezumab in the preventive treatment of migraine, to complement RCT results with evidence observed in clinical practice. METHODS A literature search was conducted to identify real-world studies evaluating galcanezumab in the treatment for patients with migraine. RESULTS Twenty-five studies were identified; some only evaluated galcanezumab, and others used pooled data from multiple anti-CGRP antibodies. The studies recruited diverse patient populations, including patients who had failed multiple prior preventive therapies. Treatment was associated with significant reductions from baseline in monthly migraine days and monthly headache days by 4.3 to 12.9 and 3.1 to 13.9, respectively. These values were numerically greater than those reported in most galcanezumab RCTs. Significant decreases from baseline were evident within the first month of treatment, and efficacy was maintained throughout the follow-up periods, ranging from 3 to 12 months. Galcanezumab was also associated with improvements in other efficacy end points, including decreased headache pain intensity, reduction in analgesic use, and improvements in daily functioning and quality of life. Functionality scores, as assessed by the Migraine Disability Assessment Scale questionnaire, decreased by 27 to 75 points from baseline at 3 to 12 months. Galcanezumab was associated with a low discontinuation rate and higher rates of persistence compared with standard migraine preventive treatments. CONCLUSIONS The results provide complementary data that galcanezumab is effective across the diverse patient populations observed in routine clinical practice.

Abstract
To assess factors associated with galcanezumab response in a real-world study of Korean patients with migraine. Predictors of the efficacy of monoclonal antibodies targeting calcitonin gene-related peptide (CGRP) or its receptor (anti-CGRP(-R) mAb) have been rarely investigated in Asians. We prospectively recruited and followed up patients with migraine who received monthly galcanezumab treatment in a single university hospital from June 2020 to October 2021. We defined the treatment response with ≥ 50% reduction in moderate/severe headache days in the 3rd month of treatment compared to baseline. Responders and non-responders were compared in terms of demographics, disease characteristics and severity, and previous response to migraine prophylactic treatments. Potential predictors of anti-CGRP(-R) mAb response were tested by using the univariable and multivariable logistic regression analyses. Among 104 patients (81.7% female; mean age 42.0 ± 13.02; 76.9% chronic migraine; and 45.5% medication overuse headache) included, 58 (55.7%) were responders. Non-responders had more chronic migraine, medication overuse headache, monthly headache days, days with acute medication, and daily headaches (i.e. chronic migraine persisting everyday without remission). The multivariable logistic analysis showed chronic migraine (OR 0.05 [95% CI 0.00-0.82], p = 0.036) and the number of previously failed preventive medication classes (OR 0.55 [95% CI 0.33-0.92], p = 0.024] were independently associated with treatment response. Chronic migraine and multiple failures from preventive medication are associated with poor galcanezumab response. Further studies are needed to investigate if earlier treatment before disease chronification or multiple failures may lead to a greater therapeutic gain from anti-CGRP(-R) mAb treatment.

Abstract
BACKGROUND In real-world studies, it is unclear whether galcanezumab has a significant effect in the first week after administration. METHODS We retrospectively assessed 55 high-frequency episodic migraine (HFEM) and chronic migraine patients who received three galcanezumab doses. Mean changes in the numbers of weekly migraine days (WMDs) during month 1 and migraine days per month (MMDs) after 1-3 months of treatment were obtained. Clinical factors related to a ≥ 50% response rate (RR) at month 3 were analyzed. The prediction of ≥ 50% responders at month 3 using different weekly RRs at week 1 (W1) was evaluated. The RR at W1 was calculated with the following formula: RR (%) = 100 - [(WMDs at W1/baseline WMD) × 100]. RESULTS The number of MMDs significantly improved from baseline to 1, 2 and 3 months. The ≥ 50% RR was 50.9% at 3 months. The number of WMDs decreased significantly from baseline to week 1 (- 1.6 ± 1.7 days), week 2 (- 1.2 ± 1.6 days), week 3 (- 1.0 ± 1.3 days), and week 4 (- 1.1 ± 1.6 days) during month 1. The RR at W1 was largest (44.6 ± 42.2%). The ≥ 30%, ≥ 50% and ≥ 75% RRs at W1 were significantly predictive of a ≥ 50% RR at 3 months. Logistic regression analysis predicting a ≥ 50% RR at month 3 showed that the RR at W1 was the sole contributing factor. CONCLUSION In our study, galcanezumab showed a significant effect in the first week after administration, and the RR at W1 could predict the RR at 3 months.

Abstract
Calcitonin gene-related peptide-targeted monoclonal antibodies (CGRP mAbs) are increasingly being used as preventive treatments for migraine. Their effectiveness and safety were established through numerous randomized placebo-controlled trials and real-world studies, yet a significant proportion of patients do not respond to this treatment, and currently, there is a lack of accepted predictors of response to guide expectations, as data from studies so far are lacking and inconsistent. We searched Embase and MEDLINE databases for studies reporting on predictors of response to CGRP and/or CGRP-receptor (CGRP-R) mAbs, defined as a 30% or 50% reduction in monthly headache or migraine days at varying durations of follow-up. Quantitative synthesis was performed where applicable. We found 38 real-world studies that investigated the association between various predictors and response rates. Based on these studies, good response to triptans and unilateral pain with or without unilateral autonomic symptoms are predictors of a good response to CGRP(-R) mAbs. Conversely, obesity, interictal allodynia, the presence of daily headaches, a higher number of non-successful previous prophylactic medications, and psychiatric comorbidities including depression are predictive of a poor response to CGRP(-R) mAbs. Future studies should confirm these results and help to generate more tailored treatment strategies in patients with migraine.

J Headache Pain 2023; 24:75. [PMID: 37344811 DOI: 10.1186/s10194-023-01611-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Accepted: 06/10/2023] [Indexed: 06/23/2023] Open
Abstract
BACKGROUND Real-world data are accumulating on the effectiveness, tolerability and safety of anti-calcitonin gene-related peptide pathway monoclonal antibodies for the preventive treatment of migraine. We performed a systematic review of the methodology of prospective, observational, clinic-based real-world evidence studies with these drugs in both episodic and chronic migraine. METHODS The objectives were to evaluate the definitions and reported outcomes used, and to perform a risk of bias assessment for each of the different studies. PubMed and EMBASE were systematically queried for relevant scientific articles. Study quality assessment of the included studies was conducted using the "National Heart, Lung and Blood Institute (NHLBI) Study Quality Assessment Tool for Before-After (Pre-Post) Studies with No Control Group". RESULTS Forty-six studies fitted the criteria for the systematic review and were included in the analysis. Ten studies (21.7%) defined a migraine day for the study, while only 5 studies defined a headache day for the study (10.9%). The most common primary endpoint/objective of the studies was change in monthly migraine days (n = 16, 34.8%), followed by responder rate (n = 15, 32.6%) and change in monthly headache days (n = 5, 10.9%). Eight studies (17.4%) did not define the primary endpoint/objective. Thirty-three studies were graded as "good" quality and 13 studies were graded as "fair". CONCLUSION Our analysis shows rather significant heterogeneity and/or lack of predefined primary outcomes/objectives, definitions of outcomes measures and the use of longitudinal monitoring (e.g. headache diaries). Standardization of terminology, definitions and protocol procedures for real-world evidence studies of preventive treatments for migraine are recommended. TRIAL REGISTRATION This study was registered with PROSPERO with ID CRD42022369366.

Abstract
Background: Calcitonin gene-related peptide (CGRP) targeted therapies are an important breakthrough in migraine prevention. Randomized clinical trials, post-hoc analyses, and phase IV studies have demonstrated their efficacy and safety in chronic migraine patients, including those with concomitant medication-overuse and medication-overuse headache. Real world evidence studies support these findings and provide realistic endpoints for estimation of effect. Methods and results We have performed a narrative review including results from double-blind placebo-controlled randomized clinical trials and real-world evidence studies regarding efficacy of the CGRP(-receptor) monoclonal antibodies and CGRP-receptor antagonists (gepants) in patients with chronic migraine with concomitant medication overuse (headache). We have included patient profiles and main efficacy endpoints (monthly migraine days, monthly headache days, monthly acute medication days and percentage responder rates). Conclusion The results of this review show that CGRP monoclonal antibodies are effective in chronic migraine patients, also in those with medication overuse (headache). At the time of this review, atogepant clinical trials in chronic migraine have not been communicated. Direct comparative studies are needed for comparison with other treatment options.

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.

Real-world evidence of galcanezumab for migraine treatment in Japan: a retrospective analysis. BMC Neurol 2022; 22:512. [PMID: 36585619 PMCID: PMC9805082 DOI: 10.1186/s12883-022-03041-1] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Accepted: 12/21/2022] [Indexed: 01/01/2023] Open
Abstract
OBJECTIVE To evaluate the efficacy and safety of galcanezumab in patients with migraine in a real-world setting in Japan. BACKGROUND Galcanezumab is the first anti-calcitonin gene-related peptide monoclonal antibody approved in Japan. To the best of our knowledge, no real-world studies on galcanezumab have been published in any international journal from Japan. METHODS We retrospectively examined patients with migraine who received three doses of galcanezumab between August 2021 and February 2022 at the Keio University Hospital. We assessed changes in monthly migraine days, responder rate, and migraine-associated and premonitory symptoms. We also investigated injection site reactions and adverse events. RESULTS Fifty-two patients received three doses of galcanezumab during the study period. Compared with those at baseline, the monthly migraine days decreased by 5.9 days (95% confidence interval, 4.2-7.7) at 3 months. The 50% responder rate was 61.5% at 3 months. A total of 64.9%, 50.0%, and 63.9% of patients showed improvement in the severity of photophobia, phonophobia, and nausea/vomiting, respectively. Premonitory symptoms without subsequent headache were reported in 62.5% of patients. Moreover, injection site reaction was the most common adverse event (34.6%). CONCLUSION This study revealed the efficacy and safety of galcanezumab for migraineurs in Japan. Galcanezumab also improved migraine-associated symptoms. However, despite a reduction in headaches, premonitory symptoms without subsequent headache were reported in > 50% of the patients at 3 months.

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.

J Headache Pain 2022; 23:90. [PMID: 35896988 PMCID: PMC9330971 DOI: 10.1186/s10194-022-01458-0] [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: 06/08/2022] [Accepted: 07/07/2022] [Indexed: 11/20/2022] Open
Abstract
Background Galcanezumab, a humanized monoclonal antibody that binds calcitonin gene-related peptide, has demonstrated efficacy and good tolerability in patients with episodic migraine in previous phase 3 trials. We report results from the PERSIST study, which was designed to assess the efficacy and safety of galcanezumab in patients with episodic migraine from China, India, and Russia. Methods This phase 3 study was conducted at 40 centers in China (n = 26), India (n = 10), and Russia (n = 4). Eligible adult patients with episodic migraine were randomized in a 1:1 ratio to receive monthly galcanezumab 120 mg (with 240 mg loading dose) or placebo during a double-blind, 3-month treatment period. The primary endpoint was the overall mean change from baseline in monthly migraine headache days (MHDs). Key secondary endpoints were the mean proportion of patients with ≥ 50%, ≥ 75%, and 100% reductions from baseline in MHDs and mean change in the Migraine-Specific Quality of Life Questionnaire (MSQ) Role Function-Restrictive domain score. Results In total, 520 patients were randomized and received at least one dose of galcanezumab (N = 261) or placebo (N = 259). The least squares (LS) mean reduction from baseline in monthly MHDs over 3 months was significantly greater with galcanezumab compared with placebo (-3.81 days vs. -1.99 days; p < 0.0001). Significantly greater mean proportions of patients with galcanezumab versus placebo had ≥ 50%, ≥ 75%, and 100% reductions from baseline in MHDs (all p < 0.0001). The overall mean improvement from baseline in MSQ Role Function-Restrictive score over 3 months was significantly greater with galcanezumab versus placebo (p < 0.0001). There were no clinically meaningful differences between the galcanezumab and placebo group on any safety parameters except for a higher incidence of injection site pruritus (5.0% vs. 0.0%), injection site reaction (3.8% vs. 0.4%), and injection site discomfort (2.3% vs. 0.0%). TEAEs related to injection sites were mild in severity, except in 1 patient who had a moderate injection site reaction. Six serious adverse events were reported by 6 patients (2 galcanezumab, 4 placebo). Conclusions Galcanezumab 120 mg once monthly was effective and well tolerated in patients with episodic migraine from China, India, and Russia. Trial registration ClinicalTrials.gov Identifier NCT03963232 (PERSIST), registered May 24, 2019.
