Safety and efficacy of galcanezumab in patients for whom previous migraine preventive medication from two to four categories had failed (CONQUER): a multicentre, randomised, double-blind, placebo-controlled, phase 3b trial. Lancet Neurol 2020; 19:814-825. [PMID: 32949542 DOI: 10.1016/s1474-4422(20)30279-9] [Citation(s) in RCA: 152] [Impact Index Per Article: 38.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Revised: 07/08/2020] [Accepted: 07/17/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND Many patients who require migraine preventive treatment have not been able to tolerate or have not responded to multiple previous preventive medications. We aimed to assess the safety and efficacy of galcanezumab, an antibody to calcitonin gene-related peptide, in patients with migraine who had not benefited from preventive medications from two to four categories. METHODS CONQUER was a multicentre, randomised, double-blind, placebo-controlled, phase 3b trial done at 64 sites (hospitals, clinics, or research centres) in 12 countries (Belgium, Canada, Czech Republic, France, Germany, Hungary, Japan, the Netherlands, South Korea, Spain, the UK, and the USA). Patients were 18-75 years of age, with episodic or chronic migraine, with migraine onset before the age of 50 years, who had a documented failure of preventive medications from two to four drug categories in the past 10 years owing to lack of efficacy or tolerability, or both. Patients were randomised 1:1 to receive subcutaneous placebo or galcanezumab 120 mg per month (with a 240 mg loading dose administered as two 120 mg injections) for 3 months. For masking purposes, patients receiving placebo also received two injections during the first dosing visit. Randomisation was done by a computer-generated random sequence by means of an interactive web-response system stratified by country and migraine frequency (low frequency episodic migraine, four to fewer than eight migraine headache days per month; high frequency episodic migraine, eight to 14 migraine headache days per month and fewer than 15 headache days per month; chronic migraine, at least eight migraine headache days per month and at least 15 headache days per month). The primary endpoint was the overall mean change from baseline in number of monthly migraine headache days during the 3-month treatment period in all patients who were randomly assigned and received at least one dose of study drug. This trial is registered with ClinicalTrials.gov, NCT03559257, and is now completed. FINDINGS Between Sept 10, 2018, and March 21, 2019, 462 participants with episodic (269 [58%]) or chronic (193 [42%]) migraine were randomly assigned and received at least one injection with placebo (n=230) or galcanezumab (n=232). Galcanezumab-treated patients had significantly greater reduction in migraine headache days versus placebo across months 1-3. The galcanezumab group had on average 4·1 fewer monthly migraine headache days compared with baseline (13·4), while the placebo group had on average 1·0 fewer than at baseline (13·0; between-group difference -3·1 [95% CI -3·9 to -2·3]; p<0·0001; effect size=0·72). Types and number of treatment-emergent adverse events were similar between galcanezumab and placebo. Treatment-emergent adverse events were reported in 122 (53%) of 230 patients in the placebo group and 119 (51%) of 232 patients in the galcanezumab group. There were four serious adverse events during the study, two (1%) reported in the placebo group and two (1%) reported in the galcanezumab group. INTERPRETATION Galcanezumab was superior to placebo in the preventive treatment of migraine and was safe and well tolerated in patients for whom multiple previous standard-of-care preventive treatments had failed. Galcanezumab might represent an important treatment option for patients who have not benefited from or tolerated previous standard-of-care treatments. FUNDING Eli Lilly.

Abstract
The treatment of migraine is evolving to include non-traditional approaches, as pharmacologic therapy alone is unsuccessful in many patients. Daith piercing, a cartilaginous ear piercing, has become popular as a potential nonpharmacological treatment option for migraine. However, there are no systematic data on the utilization and efficacy of these piercings. Therefore, we investigated the perceptions of pediatric patients regarding Daith piercing and gathered initial retrospective data for patients who had already received it. Patients presenting to a pediatric neurology clinic were invited to complete a questionnaire to assess knowledge about and attitudes towards Daith piercing and their willingness to undergo such a treatment. For those with a Daith piercing, the effects on headaches, function, and mood were evaluated. Of the 171 respondents, 61% had prior knowledge of Daith piercings, 27% knew someone with a Daith piercing, and 60% of patients presenting with headache were willing to undergo piercing. Of the eight patients (5% of respondents) who had already undergone piercing, six (75%) reported improvement in headaches, five (62%) had missed fewer days of school or work, and seven (87%) reported mood improvement. The high proportion of pediatric patients willing to undergo this form of treatment speaks to the desire for and acceptance of nonpharmacologic treatments. Although based on a small sample, the data from children who have already undergone Daith piercing is promising and supports a need for further systematic investigation into this treatment approach.

Abstract
BACKGROUND Migraine treatment may mitigate migraine and associated pain in the perioperative period. OBJECTIVE The aim of the study was to estimate the effect of perioperative acute and prophylactic migraine treatment on the risk of postoperative 30-day hospital readmission with an admitting diagnosis specifying any pain complaints among migraine patients. DESIGN Electronic health records were analysed for 21,932 adult migraine patients undergoing surgery between 2005 and 2017 at Beth Israel Deaconess Medical Center and Massachusetts General Hospital in Boston, Massachusetts, USA. METHODS Perioperative abortive migraine treatment was defined as guideline-recommended medication (triptan, ergotamine, acetaminophen, nonsteroidal anti-inflammatory drug) prescription after surgery, within 30 days after discharge and prior readmission. Perioperatively continued prophylactic migraine treatment was defined as prescription both prior to surgery and perioperatively for recommended medications (beta-blockers, antidepressants, antiepileptics, onabotulinumtoxin A). RESULTS Overall, 10,921 (49.8%) patients received a prescription for abortive migraine drugs. Of these, 1.2% and 1.5% of patients with and without such prescription were readmitted for pain, respectively. Patients with abortive treatment had lower odds of pain-related readmission (adjusted odds ratio 0.63 [95% confidence interval 0.49-0.81]). Prophylactic migraine treatment showed no effect on pain-related readmission independently of acute treatment (adjusted odds ratio 0.97 [95% confidence interval 0.72-1.32]). CONCLUSIONS Migraine patients undergoing surgery with a perioperative prescription for abortive migraine drugs were at decreased risk of pain-related hospital readmission.

Abstract
OBJECTIVES According to the data of Organisation for Economic Cooperation and Development, almost all the countries got increased medical expenditures in these years. Among the diseases, migraine is a condition that affects predominantly young and middle-aged people. It results in great economic losses. So we perform this research to investigate the acupuncture effect of reducing medical expenditure and medical resources use. PERSPECTIVE Acupuncture is a non-pharmacologic treatment and it became popular in recent years. In Taiwan, about 13% migraine patients visited acupuncture doctor. We hypothesized that the acupuncture had the additional effect than the medical treatment. SETTING We analysed the economic cost and medical visits in the real word. METHODS We used national cohort data from Taiwan, retrospectively gathered between 2000 and 2010. We selected newly diagnosed migraine patients who were diagnosed by registered neurologists formally licensed by the Taiwan Neurological Society. We divided these patients into two groups: with and without acupuncture treatment. The main outcome was medical expenditures and visits within 1 year after acupuncture. RESULTS In migraine patients who received acupuncture treatment, medical expenditures on emergency care and hospitalization were significantly lower than the group without acupuncture treatment. CONCLUSION According to our real-world data, acupuncture can reduce the medical expenditure in migraine patients within 1 year after diagnosis. For the health policy maker, it is cost effective to encourage combining acupuncture and western medicine to treat migraine patients. For the doctors in routine clinical practice, who may consider to consult acupuncture doctors to deal with the migraine patients together.

Abstract
OBJECTIVE To evaluate fremanezumab quarterly or monthly vs placebo on health-related quality of life, health status, patients' global impression of change, and productivity in patients with chronic migraine (CM). METHODS HALO CM was a double-blind, placebo-controlled trial in patients with CM. Patients were randomized 1:1:1 to treatment with fremanezumab quarterly (675 mg at baseline, placebo at weeks 4 and 8), fremanezumab monthly (225 mg at baseline, weeks 4 and 8), or placebo. This article assessed the effect of treatment with fremanezumab on health-related quality of life and productivity using the following prespecified assessments: the Migraine-Specific Quality of Life (MSQoL) questionnaire at baseline and weeks 4, 8, and 12; Patient Global Impression of Change (PGIC) questionnaire at weeks 4, 8, and 12; and EuroQoL 5-dimension, 5-response level (EQ-5D-5L) questionnaire and Work Productivity and Activity Impairment: General Health (WPAI:GH) questionnaire at baseline and week 12. RESULTS The full analysis set included 1,121 patients: 375 patients with quarterly dosing, 375 with monthly dosing, and 371 with placebo. Fremanezumab quarterly and monthly was associated with significant improvements over placebo in change from baseline mean scores in MSQoL domains (all, p < 0.05) to week 12. At week 12, fremanezumab also showed significant improvements in EQ-5D-5L visual analog scale (p < 0.05) and PGIC scores (p < 0.0001) as well as significant reductions from baseline in WPAI:GH scores (p < 0.01) and presenteeism (impairment while working; p < 0.05) vs placebo. CONCLUSIONS Fremanezumab quarterly or monthly was associated with improvement over placebo in migraine-specific quality of life, overall health status, patients' global impression of change with treatment, and productivity in patients with CM. CLINICALTRIALSGOV IDENTIFIER NCT02621931. CLASSIFICATION OF EVIDENCE This study provides Class II evidence that in patients with CM, treatment with fremanezumab quarterly or monthly is associated with improvements in health-related quality of life and productivity.

Abstract
Background Migraine is a frequent headache disorder with high disease burden. The aims of this study were to determine the administrative prevalence and incidence of migraine in Germany; and to elucidate disease characteristics, prescription patterns and the patient journey through the German healthcare system. Methods In this retrospective, observational study, adult patients with migraine (International Classification of Diseases, 10th revision, German modification G43) were identified in the anonymised German Company Sickness Fund database (CSFD) from 2008 through 2016. The administrative prevalence and incidence of migraine were calculated for the total CSFD study population and extrapolated to the German Statutory Health Insurance (SHI) population. Migraine subtypes, concurrent diagnoses, prescription patterns and visited healthcare professional groups were analysed. Results A total of 243,471 patients with migraine were identified in the CSFD (2008–2016); 78.0% were female and 45.3% were aged 35–54 years. The administrative prevalence of migraine, extrapolated to the SHI population, ranged between 2.89% in 2008 and 3.98% in 2016; administrative incidence ranged from 0.587% in 2009 to 0.267% in 2016, and varied between 0.399% and 0.442% during 2011 to 2015. Overall, 29.1% of patients received at least one prescription for any preventive medication listed in the German guideline. Only 7.9% received the same preventive medication for more than 1 year, with 82.9% of these patients discontinuing the medication before study end. Regarding acute medications, 74.2% of prescriptions were for analgesics/non-steroidal anti-inflammatory drugs and 21.2% were for triptans. General practitioners most commonly diagnosed and treated migraine in the CSFD population. Patients with prescriptions for two or more different preventive therapy classes had higher use of acute and emergency medications, and visited healthcare professionals and hospitals more frequently than patients with no prescriptions or prescriptions for only one preventive therapy class. Conclusions The administrative prevalence of migraine in this claims database suggests many patients with migraine did not seek medical care. Of those who did, fewer than one-third received preventive medication, with most patients having been prescribed only one such medication and few having continued treatment beyond 1 year. These outcomes suggest there is scope for improvement in migraine management in Germany.

Abstract
Although the prevalence of migraine tends to decrease in the fifth to sixth decades of life, there are still a significant number of patients > 65 years of age who experience migraine or have new-onset migraine. Because these older patients are often excluded from clinical trials, there are fewer evidence-based treatment guidelines for them. Migraine treatment in the older population requires careful consideration of changes in medication metabolism and increased medical comorbidities. Furthermore, older patients can present with an atypical migraine phenotype and have a higher rate of secondary headache, which may lead to a delay in diagnosis and subsequent treatment. Classic preventive treatments for migraine, including tricyclic antidepressants, antiepileptic drugs, and beta blockers, often have intolerable side effects. In addition, the presence of coronary artery disease, stroke, and peripheral arterial disease precludes the use of typical rescue medications such as triptans. As such, there has been a dire need for novel acute and preventive treatments for older adults. The purpose of this review is to provide an update on novel acute and preventive treatments for migraine in the older population. The advantages of these therapies include their efficacy, favorable side-effect profile, particularly in patients with atherosclerotic disease, as well as their tolerability.

Abstract
Background Although the criteria for acute migraine treatment and prevention have been well described, there are still unmet needs, general underuse and low benefits of preventive drugs. The aim of the present study was to retrospectively observe the short-term effect of preventive treatment in a cohort of migraine patients attending a tertiary headache center, using data from electronic medical records. Methods This was an observational retrospective cohort study based on data collected in a tertiary headache center. Data were extracted from an electronic dataset collected from January 2009 to December 2019. The main selection criteria were as follows: age of 18–75 years; diagnosis of migraine without aura (MO), migraine with aura (MA) or chronic migraine (CM); a control visit 3 months after the first access; and prescription of preventive treatment with level of evidence 1 as reported by Italian guidelines. As the primary outcome, we considered the change in the frequency of headache at the follow-up visit. Then, as secondary outcome measures, we used disability scores, intensity of headache, and allodynia. As predictive factors, we considered age, migraine duration, sex, headache frequency, allodynia, anxiety and depression at baseline, and comorbidity with fibromyalgia. Results Among the 6430 patients screened, 2800 met the selection criteria, 1800 returned to the follow-up visit, 550 withdrew because of adverse events, and 1100 were included the analysis. One hundred thirty-four patients had a frequency reduction of 50% or more. Flunarizine was used for less severe migraine, with a better effect compared to those of other drugs (odds ratio: 1.48; p: 0.022). Low headache frequency and absent or mild allodynia predicted a better outcome. Conclusions The mild effect of preventive drugs on migraine features and even the number of patients who were lost to follow-up or dropped out because of adverse events confirm that in severe and chronic patients, the first line of prevention can only delay a more focused therapeutic approach.

Abstract
Objective: To compare the cost of adverse events (AEs) associated with preventive treatment of migraine with fremanezumab, versus erenumab, galcanezumab, and onabotulinumtoxinA.Methods: A probabilistic modeling analysis was performed, using second-order Monte Carlo simulations, with 1,000 simulations, in patients with at least 4 days of migraine per month, from the perspective of the National Health System and a time horizon of 12 weeks. The frequency of AEs described in the clinical trials was analyzed with 12 weeks of treatment. Unit costs (€) of management of AEs were obtained from public health prices, expert panels, and published Spanish studies.Results: Fremanezumab would generate average savings of -€469 (95% CI -€303; -€674) versus erenumab, -€268 (95% CI -€171; -€391) versus galcanezumab, -€1,100 (95% CI -€704; -€1,608) or -€1,295 (95% CI -€835; -€1,893) versus onabotulinumtoxinA using real-life or clinical trial data, respectively.Conclusions: The different safety profile of treatment with fremanezumab, compared to erenumab, galcanezumab, and onabotulinumtoxinA, would generate savings in health-care resources in all the scenarios considered.

Abstract
BACKGROUND Clinical trials have shown the safety and clinical superiority of erenumab compared to placebo in chronic migraine (CM). The aim of this analysis is to evaluate the effectiveness and tolerability of erenumab in a real-world setting in patients with refractory CM. METHODS This is a prospective single centre real-world audit conducted in patients with CM with and without medication overuse, refractory to established preventive medications, who received monthly erenumab for 6 months. RESULTS Of 164 patients treated, 162 patients (female = 135, mean age 46 ± 14.3 years old) were included in the audit. Patients had failed a mean of 8.4 preventive treatments at baseline and 91% of patients failed Botulinum toxin type A at baseline. The mean reduction in monthly migraine days was 6.0 days at month 3 (P = 0.002) and 7.5 days at month 6 (P < 0.001) compared to baseline. The mean reduction in monthly headache days was 6.3 days (P < 0.001) at month 3 and 6.8 days (P < 0.001) at month 6. At month 3, 49%, 35% and 13% and at month 6, 60%, 38% and 22% of patients obtained at least a 30%, 50% and 75% reduction in migraine days, respectively. The percentage of patients with medication overuse was reduced from 54% at baseline to 20% at month 3 and to 25% at month 6. Compared to baseline, the mean reduction of Headache Impact Test-6 score was 7.7 points at month 3 (from 67.6 ± 0.4 to 59.9 ± 0.9) (P < 0.001) and of 7.5 points at month 6 (60.1 ± 1.3) (P = 0.01). The percentage of patients with severe headache-related disability (HIT-6: 60-78) was reduced from 96% at baseline to 68% after three monthly treatments and to 59% after six treatments. At least one side effect was reported by 48% of patients at month 1, 22% at month 3 and 15% at month 6. Constipation (20%) and cold/flu-like symptoms (15%) were the most frequent adverse events reported. CONCLUSION Erenumab may be an effective and well tolerated therapy for medically refractory CM patients with and without medication overuse.

Abstract
Migraine is a common and disabling disorder with substantial personal, social, and economic burden that affects 37 million people in the United States. Risk factors for migraine include age, sex, and genetics. The goal of acute treatment of migraine attacks is to stop the pain and associated symptoms of the migraine attack and return the patient to normal function. The acute treatment landscape for migraine has recently expanded beyond the standard nonsteroidal anti-inflammatory drugs, analgesics, triptans, ergotamines, and combination therapies, to include neuromodulation devices, and recently approved calcitonin gene-related peptide receptor antagonists and a serotonin (5-HT1F) receptor agonist. Unmet acute treatment needs still exist due to lack of efficacy, unwanted side effects, or contraindication to treatment. Effective treatment of migraine requires the clinician to assess the patient, make an accurate diagnosis, and then offer appropriate therapy based on the patient's medical history, comorbidities, and preferences, as well as published clinical evidence. The objective of this narrative review is to familiarize primary care clinicians with the variety of acute treatment options available in the United States today based on clinical trial findings, meta-analyses, evidence-based guidelines, and professional society consensus statements.

Abstract
Background: German authorities reimburse migraine prevention with erenumab only in patients who previously did not have therapeutic success with at least five oral prophylactics or have contraindications to such. In this real-world analysis, we assessed treatment response to erenumab in patients with chronic migraine (CM) who failed five oral prophylactics and, in addition, onabotulinumtoxinA (BoNTA). Methods: We analyzed retrospective data of 139 CM patients with at least one injection of erenumab from two German headache centers. Patients previously did not respond sufficiently or had contraindications to β-blockers, flunarizine, topiramate, amitriptyline, valproate, and BoNTA. Primary endpoint of this analysis was the mean change in monthly headache days from the 4-weeks baseline period over the course of a 12-weeks erenumab therapy. Secondary endpoints were changes in monthly migraine days, days with severe headache, days with acute headache medication, and triptan intake in the treatment period. Results: Erenumab (starting dose 70 mg) led to a reduction of -3.7 (95% CI 2.4-5.1) monthly headache days after the first treatment and -4.7 (95% CI 2.9-6.5) after three treatment cycles (p < 0.001 for both). All secondary endpoint parameters were reduced over time. Half of patients (51.11%) had a >30% reduction of monthly headache days in weeks 9-12. Only 4.3% of the patients terminated erenumab treatment due to side effects. Conclusion: In this treatment-refractory CM population, erenumab showed efficacy in a real-world setting similar to data from clinical trials. Tolerability was good, and no safety issues emerged. Erenumabis is a treatment option for CM patients who failed all first-line preventives in addition to BoNTA.

Abstract
Calcitonin gene related peptide (CGRP) monoclonal antibodies (mAbs) have been the
first class of specifically developed preventive treatments for migraine.
Clinical trials data suggest superiority of the CGRP mAbs to placebo in terms of
prevention of migraine symptoms, migraine-specific quality of life and headache
related disability. Treatment-related side effects overall did not differ
significantly from placebo and discontinuation rate due to side effects has been
low across the clinical trials, perhaps in view of their peripheral mode of
action. Along with their route and frequency of administration, these novel
class of drugs may constitute an improvement compared with the established
arsenal of migraine treatments. Erenumab is a fully human antibody and the only
mAb acting on the CGRP pathway by blocking its receptor. It is the first of the
CGRP mAb class approved by the US Food and Drug Administration (May 2018) and
the European Medicines Agency (July 2018). Erenumab exists in two different
doses (70 mg and 140 mg) and it is administered with monthly subcutaneous
injections. This review summarises erenumab pharmacological characteristics,
clinical trials data, focusing on the potential role of this treatment in
clinical practice.

Abstract
BACKGROUND AND PURPOSE OnabotulinumtoxinA is an effective preventive treatment for chronic migraine (CM). In CM, in addition to a reduction in headache frequency, a decreased reliance on oral prophylactics is also indicative of treatment effectiveness. This study aimed to quantify the change in the use of oral prophylactics after treatment with onabotulinumtoxinA in patients with CM. METHODS This was a retrospective, multicentric, cross-sectional study. Patients with CM (International Classification of Headache Disorders-3beta) that had been treated with onabotulinumtoxinA were enrolled consecutively. We collected parameters related to each patient's pre-treatment situation, as well as their current situation, focusing on frequency and intensity of migraine, number of oral prophylactics and the respective cycle of onabotulinumtoxinA. Univariate and logistic regression analyses were performed. RESULTS We included 542 patients, 90.0% of whom were taking oral preventive treatments. During treatment with onabotulinumtoxinA, 47.8% withdrew at least one prophylactic and 41.6% stopped using oral prophylactics altogether. Factors associated with a reduction or cessation of oral prophylactics were >50% improvement in frequency and intensity, remission to episodic migraine, use of topiramate as an initial treatment, increased number of infiltrations and shorter chronification period (P < 0.05). The multivariate analysis showed that a chronification period <20 months, more than five cycles of onabotulinumtoxinA, >50% improvement in pain intensity and topiramate as an initial treatment were predictors of a reduction in oral prophylactics (area under the curve, 70.3%; P < 0.001). CONCLUSIONS Our study demonstrated the efficacy and safety of onabotulinumtoxinA. This treatment reduced the use of oral prophylactics. Withdrawal of oral prophylactics was most likely to occur after five cycles of treatment.

Abstract
Migraine is a debilitating neurologic disease. People who experience migraine can have substantial disability, impaired functioning and a decreased quality of life (QoL). Expert recommendations suggest that people with frequent migraine attacks or severe impairment related to attacks may benefit from preventive treatment. Despite these recommendations and the existence of evidence-based guidelines for the use of preventive medication, many people who are candidates for preventive therapies do not receive them. Thus, there is still a substantial unmet need for preventive migraine treatment. Calcitonin gene-related peptide (CGRP) has a demonstrated role in the pathophysiology of migraine. Galcanezumab-gnlm (galcanezumab) is a humanized monoclonal antibody that binds to the CGRP ligand and prevents binding to its receptor. It is administered as a once-monthly subcutaneous injection. The aim of this review is to present a comprehensive overview of the existing short- and long-term efficacy and safety data for galcanezumab in patients with migraine. Data from the phase 3, randomized, double-blind, placebo-controlled EVOLVE-1, EVOLVE-2 and REGAIN studies show that galcanezumab treatment for 3 or 6 months results in overall reduction in mean monthly migraine headache days in patients with episodic (EVOLVE-1 and EVOLVE-2) and chronic (REGAIN) migraine. Greater proportions of patients with episodic migraine receiving galcanezumab versus placebo demonstrated a ≥ 50%, ≥ 75% and 100% response to therapy and reported a lower level of disability and an improvement in functioning and QoL. Similarly, when compared with placebo, greater proportions of patients with chronic migraine treated with galcanezumab demonstrated a ≥ 50% and ≥ 75% response and reported improved functioning. A 12-month open-label study demonstrated the continued efficacy of galcanezumab for up to 12 months. In all studies galcanezumab was well tolerated. In conclusion, data from pivotal studies show that galcanezumab may fulfill an unmet need in the treatment of patients with migraine who require preventive therapy. Migraine is a significant contributor to the global burden of disease. Migraine symptoms can lead to substantial disability and can significantly impact an individual’s ability to perform everyday tasks and their overall quality of life. While individuals with infrequent migraine attacks might have success with acute treatments alone, those with more frequent attacks or who have severe migraine-related impairment may require preventive treatment. Although recommendations on the use of preventive treatment exist, only about one-third of individuals who qualify for preventive therapy actually receive it, resulting in a substantial unmet need. Calcitonin gene-related peptide (CGRP) has a demonstrated role in migraine. Galcanezumab is a humanized monoclonal antibody that binds to the CGRP ligand and prevents receptor binding. In clinical trials of patients with ≥ 4 migraine headache days per month, treatment with galcanezumab was associated with a reduction in the average number of migraine headache days per month. The majority of galcanezumab groups had greater responder rates compared with the placebo groups, and levels of disability and daily functioning were generally improved. Galcanezumab was well tolerated, with the most common adverse events being injection site reactions. The results from the clinical trials of galcanezumab suggest that this drug may fulfill an unmet need in the treatment of individuals with migraine who require preventive therapy.

Abstract
Migraine is one of top 5 medical conditions that contribute to Years Lived with Disability and affects approximately 1 billion people from around the world. To date, preventive treatment and acute therapies for migraine are limited, have undesirable side effects and are poorly tolerated in patients. In the last few decades, considerable advances in our understanding of migraine and its pathophysiology have paved the way for the development of targeted treatment options. Calcitonin gene-related peptide (CGRP) plays an integral role in the neurobiology of migraine, and new classes of drugs that target the CGRP pathway have included gepants and CGRP pathway monoclonal antibodies. Serotonin 5-HT1F receptor agonists—namely ditans—have also been developed to treat acute migraine. Lastly, non-invasive neuromodulation offers another treatment option for migraine patients who prefer treatments that have fewer side effects and are well tolerated. In this review, we discussed emerging treatment options for migraine that were made available in recent years.

Abstract
Background This study reports the long-term safety and efficacy of erenumab in chronic migraine patients. Methods This was a 52-week open-label extension study of a 12-week double-blind treatment phase study. During the double-blind treatment phase, patients received placebo or once-monthly erenumab 70 mg or 140 mg. During the open-label treatment phase, the initial monthly dose was erenumab 70 mg. Following protocol amendment, patients continued to receive erenumab 70 mg if they had already completed their Week 28 visit, otherwise, patients switched from 70 mg to 140 mg; if enrolled after the amendment, patients received 140 mg monthly throughout. Results In all, 451/609 (74.1%) enrolled patients completed the study. The exposure-adjusted patient incidence rate for any adverse event was 126.3/100 patient-years for the overall erenumab group. Overall, the adverse event profile was similar to that observed in the double-blind treatment phase. Adverse event incidence rates did not increase with long-term erenumab treatment compared with the double-blind treatment phase, and no new serious or treatment-emergent events were seen. Efficacy was sustained throughout the 52 weeks. Clinically significant reductions from double-blind treatment phase baseline (about half) were observed for monthly migraine days and migraine-specific medication days. Achievement of ≥50%, ≥75% and 100% reductions from the double-blind treatment phase baseline in monthly migraine days at Week 52 were reported by 59.0%, 33.2% and 8.9% of patients, respectively, for the combined dose group. A numerically greater benefit was observed with 140 mg compared with 70 mg at Weeks 40 and 52. Conclusions Sustained efficacy of long-term erenumab treatment in patients with chronic migraine is demonstrated, with safety results consistent with the known safety profile of erenumab and adverse event rates comparable to placebo adverse event rates in the double-blind treatment phase. Trial registration: This study is registered at ClinicalTrials.gov (NCT02174861)

Abstract
Background and objectivesThe role of serotonin–norepinephrine reuptake inhibitors (SNRIs) in migraine prophylaxis has not been completely established. Current treatments for vestibular migraine (VM) are based on scarce evidence. We aimed to perform an updated review focusing on the efficacy and tolerability of SNRIs for migraine and VM prevention.MethodsWe searched the PubMed, Web of Science, and Cochrane Library databases for relevant studies. The primary outcome was migraine frequency. In the case of VM, the Dizziness Handicap Inventory (DHI) scores and Vertigo Severity Scores (VSSs) were extracted.ResultsSix randomized controlled trials involving 418 patients were analyzed. Patients receiving SNRIs had fewer migraine days than those receiving a placebo (standardized mean difference −0.38, 95% CI −0.76 to −0.01, p=0.04). The effects of SNRIs and other active drugs were comparable. In patients with VM, venlafaxine had a significant advantage over other active drugs in decreasing the VSS (weighted mean difference (MD) −1.45, 95% CI −2.11 to −0.78, p<0.0001) and the emotional domain score of the DHI (MD −2.64, 95% CI −4.97 to −0.31, p=0.03). We found no significant difference in the rate of withdrawals due to any reason or withdrawals due to side effects between SNRIs and active drugs and between SNRIs and a placebo.ConclusionsSNRIs were clinically safe and effective for migraine and VM prophylaxis, were better than a placebo, and not inferior to other active drugs. SNRIs may be a preferable choice for patients with VM with psychiatric disorders.

Abstract
OBJECTIVE Complementary therapies have been increasingly used for the prevention and treatment of migraine so that there is a need for studies in this setting. This study sought to determine the effects of basil essential oil on the severity and frequency of migraine attack headaches. METHODS A triple-blind clinical trial study was performed on 144 patients diagnosed with migraine. Patients were randomly allocated by a stratified method to four groups of 36 titled basil essential oil 2, 4, 6%, and placebo groups. Medications were used topically every 8 h for 3 successive months. In addition, each individual received 325 mg of acetaminophen every 12 h. The severity and frequency of migraine attacks were measured prior to the study, at weeks 2, 4, 8, and 12. The visual analog scale was used to measure pain intensity. The marginal model and generalized estimation equations were used to compare changes in the intensity and frequency of pain over time. RESULTS The interaction of the dose and time factors was significant on both pain intensity (p < 0.001) and frequency of attack (p < 0.001). The odds ratio of higher pain intensity and rate ratio of higher frequency of attack in the intervention groups compared to the placebo group were decreased over the study time. CONCLUSION Time lapse and higher doses of basil essential oil would reduce both the intensity and frequency of migraine attacks.

Abstract
Introduction OnabotulinumtoxinA is approved in the USA for the prevention of headache in adults with chronic migraine, a debilitating neurologic disease characterized by headaches occurring on ≥ 15 days per month for > 3 months and including migraine features on ≥ 8 days per month. Objective The COMPEL Study (NCT01516892), a 108-week, multi-center, open-label study, evaluated the long-term efficacy and safety of onabotulinumtoxinA in adults with chronic migraine. The objective of this subanalysis was to examine the safety and tolerability of onabotulinumtoxinA after each of nine treatment cycles. Methods OnabotulinumtoxinA 155 U was administered every 12 weeks. Safety and tolerability, overall and by treatment cycle, were assessed. Treatment-emergent adverse events reported between successive treatments were attributed to the preceding treatment. The safety population received one or more doses of onabotulinumtoxinA. The primary efficacy outcome was the reduction in headache days at week 108 compared with baseline. Results Of 716 patients enrolled, 373 patients (52.1%) completed the study and 343 (47.9%) withdrew; 481 patients (67.2%) received 60 weeks of treatment and 402 (56.1%) received 108 weeks of treatment. In total, 436 (60.9%) patients reported treatment-emergent adverse events; most were mild/moderate in severity. Thirty-two patients (4.5%) discontinued the study after experiencing treatment-emergent adverse events. The incidence of treatment-emergent adverse events typically decreased with repeated onabotulinumtoxinA treatment: first cycle, 24.2%; fourth cycle, 18.4%; ninth cycle, 12.2%. Neck pain (2.7%), eyelid ptosis (1.8%), musculoskeletal stiffness (1.4%), injection-site pain (1.3%), and headache (1.3%) were the most common treatment-emergent adverse events after the first cycle. Seventy-five patients (10.5%) reported serious treatment-emergent adverse events, 13 (1.8%) withdrew. Treatment-related adverse events were reported by 131 patients (18.3%), one was considered serious. OnabotulinumtoxinA significantly reduced headache day frequency by 10.7 (6.4) days per 28-day period (p < 0.0001) at week 108. Conclusions OnabotulinumtoxinA treatment was well tolerated over 108 weeks; no new safety signals were identified. The overall incidence of treatment-emergent adverse events and the most common individual events decreased with repeated onabotulinumtoxinA administration.

Abstract
Objective: Despite the high prevalence and disabling nature of migraine, studies evaluating its economic burden in Singapore remain scant. This study aims to quantify the per capita and aggregate economic cost of episodic migraine (EM; ≤14 monthly headache days) without aura among full-time employees in Singapore. Methods: We administered a cross-sectional online survey to full-time employees in Singapore who met the International Classification of Headache Disorders (third edition, 2018) criteria for EM without aura. Eligible participants were classified by the frequency of monthly migraine days (MMDs): lower end episodic migraine (LEM; ≤3 MMDs) and upper end episodic migraine (UEM; 4–14 MMDs). The survey captured per capita healthcare resource utilization and lost work productivity (absenteeism and presenteeism) for each subgroup. Healthcare costs were obtained by multiplying unit costs by healthcare utilization. Finally, per capita (patient) costs of each subgroup were then imputed and multiplied by prevalence data to quantify the aggregate burden of migraine in Singapore. Results: Of the 606 participants who completed the survey, 81% experienced ≤3 MMDs. Total annual per capita costs were SGD4925 (USD 3620; 95% confidence interval (CI): SGD 4438–5411) and SGD14,476 (USD 10,639; 95% CI: SGD 11,908–17,045) for the LEM and UEM subgroup, respectively. Healthcare costs on average accounted for 17.6% of per capita costs, of which was driven primarily by diagnostic tests (33.6%), followed by consultations (17.1%), medications (16.7%), alternative medications (16.6%) and hospitalizations (14.8%). Lost productivity accounted for 82.4% of costs, chiefly attributable to absenteeism in the LEM group (38.2%), followed by presenteeism in the UEM group (26.0%), absenteeism in the UEM group (18.8%) and presenteeism in the LEM group (17.1%). The total cost to Singapore for EM in 2018 was approximately SGD 1 billion (USD 0.75 billion; SGD 1.00 = USD 0.74). Conclusion: Overall, EM imposes a substantial economic burden on society in Singapore. Total migraine cost per capita is greater in the UEM (4–14 MMDs) as compared to the LEM subgroup. Majority of the overall costs result from missed workdays and lost work productivity. Future research should determine the extent to which optimized migraine treatments could improve productivity, and by extension, mitigate the staggering costs of this disorder.

Abstract
BACKGROUND Migraine is a chronic disorder that negatively affects a patient's quality of life (QOL). As little is known about the QOL of migraine sufferers in Saudi Arabia, our aim was to investigate the QOL and the level of migraine-associated disability of migraine patients. MATERIALS AND METHODS This cross-sectional study was conducted in neurology clinics at King Abdulaziz Medical City for National Guard and Prince Sultan Military Medical City in Riyadh, Saudi Arabia, from August to December 2018. The migraine-specific QOL questionnaire (MSQ), version 2.1, was used to measure restrictive, preventive, and emotional domains. The sum of the item responses ranged between 0 and 100, with higher scores indicating better QOL. A descriptive analysis of numerical variables was reported in terms of means and standard deviation, while categorical variables were described using frequencies and percentages. RESULTS A total of 300 migraine patients completed the questionnaire; 67% were females. Age of participants ranged from 20 to 53 years, with mean age of 34.21 (SD=7.26). The mean score in the QOL restrictive domain was 51.8 ± 19, whereas the mean scores for preventive and emotional domains were 54 ± 18 and 46.3 ± 23.4, respectively. Low QOL scores were associated with young ages, long disease duration, frequent migraine attacks, and presence of chronic diseases. CONCLUSION Chronic migraine has a negative impact on QOL, predominantly in young patients, patients with frequent attacks, those not using preventive medications, and those suffering from chronic diseases.

Safety and tolerability of monthly galcanezumab injections in patients with migraine: integrated results from migraine clinical studies. BMC Neurol 2020; 20:25. [PMID: 31952501 PMCID: PMC6966798 DOI: 10.1186/s12883-020-1609-7] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Accepted: 01/09/2020] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Galcanezumab, a humanized monoclonal antibody that selectively binds to calcitonin gene-related peptide, has demonstrated a significant reduction in monthly migraine headache days in phase 2 and 3 trials. In these analyses, we aimed to evaluate the safety and tolerability of galcanezumab compared with placebo for prevention of episodic or chronic migraine. METHODS Data were integrated from three double-blind clinical studies for the up to 6-month galcanezumab exposure group (N = 1435), and from five clinical studies for the up to 1-year all-galcanezumab exposure group (N = 2276). Patients received a monthly 120 mg subcutaneous injection of galcanezumab (with a 240 mg loading dose in month 1), 240 mg galcanezumab, or placebo. Outcomes measured were treatment-emergent adverse events (TEAEs), serious AEs (SAEs), and discontinuation due to AEs (DCAEs). Laboratory results, vital signs, electrocardiogram (ECG), suicidal ideation and behavior results were evaluated. RESULTS TEAEs that occurred more frequently in galcanezumab-treated patients included injection site pain, injection site reactions excluding pain, constipation, vertigo, and pruritus. The proportion of DCAEs among galcanezumab-treated patients ranged between 1.8 and 3.0%, and differed from placebo group for galcanezumab 240 mg (P < 0.05). Fewer than 2.0% of patients in either galcanezumab dose-group compared with 1.0% of placebo-treated patients reported a SAE. There were no clinically meaningful differences between galcanezumab and placebo in laboratory measures, vital signs including blood pressure, ECGs, cardiovascular-related AEs, or suicidal ideation and behavior. CONCLUSIONS Galcanezumab demonstrated a favorable safety and tolerability profile for up to 1 year of treatment for the prevention of migraine. TRIAL REGISTRATION Clinical Trials CGAB = NCT02163993, EVOLVE-1 = NCT02614183, EVOLVE-2 = NCT02614196, REGAIN = NCT02614261, and CGAJ = NCT02614287.

Abstract
Many new medications for the treatment of migraine are now available on the market. In the current evolving migraine treatment landscape, an individualized treatment approach is needed. This review provides practical recommendations on how to obtain a correct diagnosis and then engage in a long-term partnership with patients with the most severe form of migraine: chronic migraine (CM). Given the need to effectively treat this complex neurological disease, clinicians in primary care, general neurologists, and headache specialists are at the forefront to ease the burden of this disease for their patients. This manuscript will review how to discuss the currently available treatment options to help control migraine attacks, manage expectations, and, together with the patient, determine the most effective and appropriate treatment. The goal is to create an environment where the clinician partners with the patient in shared decision-making to choose the most effective appropriate treatment for the individual patient.

Abstract
Objective: Despite guidelines that identify potential patients eligible for preventive migraine medications, their underutilization leaves patients at risk of acute medication overuse, disease progression, and higher healthcare resource utilization and disability. This exploratory, retrospective, observational study aimed to identify which factors predict preventive migraine medication initiation. Demographics and initiation of acute medication use were hypothesized to be predictive of initiation of preventive migraine medication.Methods: The Truven Health Analytics MarketScan1 U.S. Commercial and Medicare Supplemental claims database (2011-2013) was used to identify adults newly diagnosed with migraine. Patients were divided into 2 subgroups: initiated a preventive migraine medication (antidepressants, anti-epileptics, beta-blockers, or neurotoxins) within 1 year of migraine diagnosis and did not initiate a preventive migraine medication. Logistic regression models were constructed to identify factors associated with preventive migraine medication initiation.Results: Study population included 147,923 patients: 43,660 preventive migraine medication initiators and 104,263 non-preventive migraine medication patients. Best-fit model for predicting preventive migraine medication initiation included: female gender (odds ratio = 1.181 [95% CI = 1.144,1.218]; measured at date of first migraine diagnosis); headache diagnosis prior to migraine diagnosis (odds ratio = 1.538 [95% CI = 1.498,1.579]; measured 1-year before first migraine diagnosis); and sleep disorder (odds ratio = 1.206 [95% CI = 1.161,1.252]), headache/migraine-specific Emergency Department (ED) visit (odds ratio = 1.224 [95% CI = 1.168,1.283]), neurologist visit (odds ratio = 1.502 [95% CI = 1.459,1.547]), and acute medication refills with <90-day gap (odds ratio = 1.509 [95% CI = 1.470,1.549]) each measured at 1-year before first preventive migraine medication.Conclusions: In addition to consistent acute medication refills, specific comorbidity diagnoses, headache/migraine-specific ED utilization, and neurologist care are predictive of preventive migraine medication initiation in the 1-year post-incident migraine diagnosis.

Abstract
Objective To examine the cardiovascular, cerebrovascular, and peripheral vascular safety of erenumab across migraine prevention studies. Methods Vascular adverse events (AEs) and blood pressure data were integrated across 4 double-blind, placebo-controlled studies of erenumab and their open-label extensions in patients with chronic or episodic migraine. Subgroup analyses were conducted by acute migraine-specific medication use and number of vascular risk factors at baseline. Standardized search terms were used to identify vascular AEs (cardiovascular, cerebrovascular, or peripheral). An independent committee adjudicated whether targeted events were vascular in origin. Results In placebo-controlled studies, 2,443 patients received placebo (n = 1,043), erenumab 70 mg (n = 893), or erenumab 140 mg (n = 507) subcutaneously once monthly. Regardless of acute migraine-specific medication use or vascular risk factors at baseline, AE incidence was similar across the placebo and erenumab treatment groups. Hypertension AEs were reported for 0.9% (placebo), 0.8% (erenumab 70 mg), and 0.2% (erenumab 140 mg) of patients. Vascular AEs, which were similar across double-blind and open-label treatment, generally were confounded, with plausible alternative etiologies. In 18 patients with events reviewed by the independent committee, 4 events were positively adjudicated as cardiovascular in origin: 2 deaths and 2 vascular events. All 4 positively adjudicated cardiovascular events occurred during open-label erenumab treatment. Conclusion Selective blockade of the canonical calcitonin gene-related peptide receptor with erenumab for migraine prevention had a vascular safety profile comparable to that of placebo over 12 weeks, with no increased emergence of events over time. Further study of long-term safety of erenumab in patients with migraine is needed. Clinicaltrials.gov identifiers NCT02066415, NCT02456740, NCT01952574, NCT02483585, NCT02174861, and NCT01723514. Classification of evidence This analysis provides Class II evidence that for patients with migraine, erenumab does not increase the risk of vascular AEs.

Abstract
ObjectiveTo assess the efficacy of erenumab across the spectrum of response thresholds (≥50%, ≥75%, 100%) based on monthly migraine days (MMD) reduction in patients with chronic migraine from a 12-week, randomized study (NCT02066415).MethodsPatients (n = 667) received (3:2:2) placebo or erenumab 70/140 mg once-monthly. The proportion of patients achieving a given response threshold was assessed. A post-hoc analysis was conducted to contextualize the actual treatment benefit in subgroups of patients achieving (or not) specified response thresholds. Outcome measures included MMD, acute migraine-specific medication treatment days (MSMD) and disability.ResultsThe proportion of patients responding to erenumab exceeded that of placebo at the ≥50% and ≥75% response thresholds. At month 3, 39.9% and 41.2% of patients on erenumab 70 and 140 mg, respectively, achieved ≥50% response versus placebo (23.5%). Similarly, at month 3, 17.0% and 20.9% of patients on erenumab 70 and 140 mg, respectively, achieved ≥75% response versus placebo (7.8%). Compared with the overall erenumab-treated population (change in MMD: −6.6 [both 70 and 140 mg]), ≥50% responders showed MMD reductions of −12.2/−12.5 for 70 mg/140 mg versus −2.6/−2.2 for those not achieving ≥50% response. ≥75% responders showed MMD reductions of −13.9/−14.8 for 70 mg/140 mg versus −5.0/−4.3 for those not achieving ≥75% response. Relative improvements in MSMD and disability were observed in responders versus overall erenumab-treated population.ConclusionFor erenumab-treated patients achieving ≥50% response, the actual reduction in MMD was almost twice that of the overall population. These findings provide context for setting realistic expectations regarding actual treatment benefit experienced by patients responding to treatment.

Abstract
BACKGROUND Novel therapeutic options with improved efficacy and safety profiles are needed for the prophylaxis of migraine. In recent years, the inhibition of calcitonin gene-related peptide (CGRP) signaling has attracted growing interest in the pharmacological research on migraine. Erenumab is the first fully human monoclonal antibody directed against the CGRP receptor to be approved for use in migraineurs. OBJECTIVE To evaluate the efficacy and safety of erenumab as preventive treatment in patients with migraine using meta-analytical techniques. METHODS Randomized, placebo-controlled, single- or double-blinded trials were identified through a systematic literature search (October week 4, 2018). Main outcomes included the changes from baseline in monthly migraine days (MMD) and monthly acute migraine-specific medication days (MSMD) at week 12, and the incidence of adverse events (AEs), severe AEs (SAEs) and treatment withdrawal due to AEs. Mean difference (MD) and risk ratio (RR) with 95% confidence intervals (95% CIs) were estimated. RESULTS Across the five included trials, erenumab given as a subcutaneous injection at a monthly dosage of 70 mg and 140 mg was associated with a significantly greater reduction in baseline MMD (70 mg: MD - 1.3, 95% CI - 1.7 to - 1.0, p < 0.001; 140 mg: MD - 1.9, 95% CI - 2.3 to - 1.4, p < 0.001) and MSMD (70 mg: MD - 1.0, 95% CI - 1.6 to - 0.4, p < 0.001; 140 mg: MD - 1.8, 95% CI - 2.5 to - 1.1, p < 0.001) than placebo. There were no differences in the occurrence of AEs, SAEs, and drug withdrawal due to AEs between the erenumab and placebo groups. CONCLUSIONS Erenumab is an efficacious and well tolerated preventive treatment in adult patients with episodic and chronic migraine.

Abstract
BACKGROUND Antibodies targeting calcitonin gene-related peptide (CGRP) or its receptor have shown efficacy in the prevention of migraine attacks. We investigated the efficacy and tolerability of fremanezumab, a fully humanised CGRP antibody, in patients with migraine who had previously not responded to two to four classes of migraine preventive medications. METHODS The randomised, double-blind, placebo-controlled, parallel-group, phase 3b FOCUS trial was done at 104 sites (including hospitals, medical centres, research institutes, and group practice clinics) across Belgium, the Czech Republic, Denmark, Finland, France, Germany, Italy, the Netherlands, Poland, Spain, Sweden, Switzerland, the UK, and the USA. We enrolled participants aged 18-70 years with episodic or chronic migraine who had documented failure to two to four classes of migraine preventive medications in the past 10 years. Failure was defined as no clinically meaningful improvement after at least 3 months of therapy at a stable dose, as per the treating physician's judgment; discontinuation because of adverse events that made treatment intolerable; or treatment contraindicated or unsuitable for the preventive treatment of migraine for the patient. Participants were randomly assigned (1:1:1) by electronic interactive response technology to subcutaneously administered quarterly fremanezumab (month 1, 675 mg; months 2 and 3: placebo), monthly fremanezumab (month 1: 225 mg in episodic migraine and 675 mg in chronic migraine; months 2 and 3: 225 mg in both migraine subgroups), or matched monthly placebo for 12 weeks. The primary outcome was mean change from baseline in the monthly average number of migraine days during the 12-week treatment period. This trial is registered with ClinicalTrials.gov, number NCT03308968, and is now completed. FINDINGS Between Nov 10, 2017, and July 6, 2018, 838 participants with episodic (329 [39%]) or chronic (509 [61%]) migraine were randomly assigned to placebo (n=279), quarterly fremanezumab (n=276), or monthly fremanezumab (n=283). Reductions from baseline in monthly average migraine days over 12 weeks were greater versus placebo (least-squares mean [LSM] change -0·6 [SE 0·3]) with quarterly fremanezumab (LSM change -3·7 [0·3]; LSM difference vs placebo -3·1 [95% CI -3·8 to -2·4]; p<0·0001) and with monthly fremanezumab (LSM change -4·1 [0·34]; LSM difference vs placebo -3·5 [-4·2 to -2·8]; p<0·0001). Adverse events were similar for placebo and fremanezumab. Serious adverse events were reported in four (1%) of 277 participants with placebo, two (<1%) of 276 with quarterly fremanezumab, and four (1%) of 285 with monthly fremanezumab. INTERPRETATION Fremanezumab was effective and well tolerated in patients with difficult-to-treat migraine who had previously not responded to up to four classes of migraine preventive medications.

Abstract
Importance Galcanezumab (LY2951742), a monoclonal antibody against calcitonin gene-related peptide (CGRP), is one of a novel class of new medicines for migraine prevention. Objective To assess whether at least 1 dose of galcanezumab was superior to placebo for episodic migraine prevention. Design, Setting, and Participants A randomized clinical trial was conducted in the United States (July 7, 2014, to August 19, 2015) in clinics of 37 licensed physicians with a specialty including, but not limited to, psychiatry, neurology, internal medicine, and primary care. Subcutaneous injections of galcanezumab, 5, 50, 120, or 300 mg, or placebo were given monthly during the 3-month treatment period. A total of 936 patients were assessed; 526 did not meet study entry or baseline criteria and 410 patients were randomly assigned to receive placebo or galcanezumab. Analyses were conducted on an intent-to-treat population, which included all patients who were randomized and received at least 1 dose of study drug. Interventions Short-term migraine treatments were allowed as needed except for opioids or barbiturates. Main Outcomes and Measures To determine if at least 1 of the 4 doses of galcanezumab tested was superior to placebo for migraine prevention measured by the mean change from baseline in the number of migraine headache days 9 weeks to 12 weeks after randomization. Results Of the 936 patients assessed, 410 met entry criteria (aged 18-65 years with 4-14 migraine headache days per month and migraine onset prior to age 50 years) and were randomized to receive placebo or galcanezumab. For the primary end point, galcanezumab, 120 mg, significantly reduced migraine headache days compared with placebo (99.6% posterior probability -4.8 days; 90% BCI, -5.4 to -4.2 days vs 95% superiority threshold [Bayesian analysis] -3.7 days; 90% BCI, -4.1 to -3.2 days). Adverse events reported by 5% or more of patients in at least 1 galcanezumab dose group and more frequently than placebo included injection-site pain, upper respiratory tract infection, nasopharyngitis, dysmenorrhea, and nausea. Conclusions and Relevance Monthly subcutaneous injections of galcanezumab, both 120 mg and 300 mg, demonstrated efficacy (repeated-measures analysis) for the preventive treatment of migraine and support further development in larger phase 3 studies. All dosages were safe and well tolerated for the preventive treatment of episodic migraine. Trial Registration clinicaltrials.gov Identifier: NCT02163993.

Abstract
Background Chronic migraine is a disabling condition that is currently underdiagnosed and undertreated. In this narrative review, we discuss the future of chronic migraine management in relation to recent progress in evidence-based pharmacological treatment. Findings Patients with chronic migraine require prophylactic therapy to reduce the frequency of migraine attacks, but the only currently available evidence-based prophylactic treatment options for chronic migraine are topiramate and onabotulinumtoxinA. Improved prophylactic therapy is needed to reduce the high burden of chronic migraine in Italy. Monoclonal antibodies that target the calcitonin gene-related peptide (CGRP) pathway of migraine pathogenesis have been specifically developed for the prophylactic treatment of chronic migraine. These anti-CGRP/R monoclonal antibodies have demonstrated good efficacy and excellent tolerability in phase II and III clinical trials, and offer new hope to patients who are currently not taking any prophylactic therapy or not benefitting from their current treatment. Conclusions Treatment of chronic migraine is a dynamic and rapidly advancing area of research. New developments in this field have the potential to improve the diagnosis and provide more individualised treatments for this condition. Establishing a culture of prevention is essential for reducing the personal, social and economic burden of chronic migraine.

Abstract
OBJECTIVE To clarify whether the clinical response after the first 2 cycles with Onabotulinumtoxin A can accurately predict the long-term response. BACKGROUND Onabotulinumtoxin-A (OBT-A) is an approved preventive treatment option for chronic migraine (CM). Nowadays, it remains to be clarified if the treatment has to be prolonged for at least an entire year (4 injections every 3 months - ie, quarterly, as proposed in the PREEMPT trials) or it can be halted after the second or third injection if not clinically effective. DESIGN AND METHODS We conducted a multicenter observational cohort study based on real-life data on the usage of OBT-A in CM patients from 2 Italian headache centers, Roma Campus Bio-Medico and Milano Besta, adopting the whole 4-injections protocol. We performed a retrospective analysis of medical records of consecutive patients treated in the 2 centers. The main statistical analysis aimed to evaluate longitudinal measures related to headache (monthly headache frequency, monthly number of analgesic drugs, MIDAS). We hypothesized from our clinical practice with OBT-A that only 2 cycles of treatment were not enough to actually define the non-responder status to botulinum toxin A and that probably a longer time of treatment is needed to get the condition of long-term (delayed) responder. RESULTS We considered 115 patients from the 2 centers: 53 in Roma and 62 in Milano. Regarding the main analysis, a clear improvement in each measure was obtained at the 6 months assessment and maintained up to 12 months. Comparing patients with <30% and ≥30% reduction in headache frequency between T0 and T2 or T4 (respectively, "Non-Responders" and "Responders"), we found that the agreement between the classification Responders/Non-Responders at T2 and T4 was not very high (79/104 = 76.0%, with a "moderate" Cohen's Kappa of 0.51), suggesting that the status at T4 is not fully predictable by the status at T2 (λ = 0.47). Responders for headache frequency at T4 were 54.8%. Among Responders at T2, Responders at T4 were 47/62 = 75.8% (95% CI: 64.5%, 85.5%), while among Non-Responders at T2, Responders at T4 were 10/42 = 23.8% (95% CI: 11.9%, 38.1%). Similarly, even when considering the 50% reduction in painkillers consumption or in MIDAS total score between T0 and T2 as possible prognostic factors, the changes occurring at T4 are not strongly predictable by those at T2. CONCLUSIONS A ≥30% reduction in headache frequency at T2 cut-off is not adequate in predicting a late response to treatment: more than a quarter of excluded patients would miss a clinical improvement with an ongoing treatment, while in a similar percentage of Responders the treatment would lose efficacy. Results from our real-life study suggest that we possibly have to postpone the definition of Responder/Non-Responder to OBT-A at least after 1 year of treatment (4 cycles).

Abstract
Purpose The newly developed calcitonin gene-related peptide (CGRP) antagonists were recently launched on the US and European market, with Switzerland as the second country worldwide. To enable forthcoming comparisons with established migraine therapy, the aim of this study was to provide a comprehensive picture of migraine (prophylactic) treatment patterns. Recent data in daily clinical practice are lacking. Patients and methods This population-based cohort study included enrollees from a Swiss Healthcare Insurance Database with at least one triptan prescription in 2015. Treatment patterns were defined by assessing subsequent triptan and prophylactic medication use (after index prescription for triptan) within the following year, divided into four quarters. Results Triptans were used by 10,090 patients (1.3%) in 2015. Most of them used triptan only (82.6%), 12.9% changed the treatment between triptan and prophylactics, and 4.5% received both in combination within 1year. Among triptan users with ≥1 prophylactic prescription in the first quarter, 48.6% used beta-blockers (BB), 40.7% “other prophylactics than BB (eg, topiramate)”, and 10.7% “a combination of both”. Most patients who received both BB and other prophylactics in the first quarter used this drug combination continuously over all four quarters. Conclusion This study provides comprehensive data on treatment patterns prior to the introduction of a new drug class in migraine therapy. The majority of triptan users had no prophylactic medication therapy; however, a small, but relevant group used BB and other prophylactics concurrently in all quarters. Findings quantify the population in potential need for optimized migraine therapy, ie, the potential target population of the novel CGRP-targeted drugs.

Abstract
Already a well-established treatment for different autonomic and movement disorders, the use of botulinum toxin type A (BoNT/A) in pain conditions is now continuously expanding. Currently, the only approved use of BoNT/A in relation to pain is the treatment of chronic migraines. However, controlled clinical studies show promising results in neuropathic and other chronic pain disorders. In comparison with other conventional and non-conventional analgesic drugs, the greatest advantages of BoNT/A use are its sustained effect after a single application and its safety. Its efficacy in certain therapy-resistant pain conditions is of special importance. Novel results in recent years has led to a better understanding of its actions, although further experimental and clinical research is warranted. Here, we summarize the effects contributing to these advantageous properties of BoNT/A in pain therapy, specific actions along the nociceptive pathway, consequences of its central activities, the molecular mechanisms of actions in neurons, and general pharmacokinetic parameters.

Abstract
Background Migraine is a common and severely disabling neurological disorder affecting millions of patients in Europe. Despite the availability of evidence-based national and international guidelines, the management of migraine patients often remains poor, which is often attributed to a low availability of headache specialists. The aim of this study was to investigate the adherence to national guidelines and to assess the possible potential of optimized therapy regimens in migraine patients. Methods We collected data of migraine patients presenting to our out-patient clinic via standardized questionnaires regarding headache, diagnostics and experience with previous treatments. We also assessed the efficacy of treatment started by our center. Results 1,935 migraine patients were included between 2010 and 2018. In the 12 months before consulting our headache clinic 89.5% of the patients had consulted a general practitioner and 74.9% had consulted a neurologist because of their migraine. Nevertheless, 50% of the patients underwent unnecessary diagnostics and 34.2% had not been treated according to evidence-based treatment guidelines. Out of 1,031 patients who had not been prescribed a preventative treatment 627 (60.8%) had in average 3 or more migraine attacks per month and thus qualified for a preventative treatment. These patients missed in the 3 months prior to consultation on average 5 work or school days. Initiating a preventative treatment was effective in 71.2% of the patients, that provided follow-up data. Conclusions Our data suggest, that many migraine patients to this day do not receive state-of-the-art therapy. Adherence to national and international European guidelines could improve the outcome in migraine patients. Future research should try to answer why guidelines are not followed.

Onset of efficacy and duration of response of galcanezumab for the prevention of episodic migraine: a post-hoc analysis. J Neurol Neurosurg Psychiatry 2019; 90:939-944. [PMID: 31004075 PMCID: PMC6691875 DOI: 10.1136/jnnp-2018-320242] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2018] [Revised: 03/05/2019] [Accepted: 03/18/2019] [Indexed: 01/17/2023]
Abstract
BACKGROUND AND OBJECTIVE As new migraine prevention treatments are developed, the onset of a preventive effect, how long it is maintained and whether patients initially non-responsive develop clinically meaningful responses with continued treatment can be assessed. METHODS Analyses were conducted post-hoc of a double-blind, placebo-controlled, phase II-a study in patients with episodic migraine receiving galcanezumab 150 mg or placebo biweekly for 12 weeks (Lancet Neurol 13:885, 2014). The number of migraine headache days per week, and onset of efficacy measured as the first week galacanezumab separated from placebo were determined. Patients with ≥50%, ≥75% and 100% reduction in migraine headache days from baseline at months 1, 2 and 3 were calculated and defined as sustained responses. Non-responders (<50% response) at month 1 or 2 who then showed ≥50%, ≥75% and 100% response at later time-points were calculated. RESULTS Patients were randomised to galcanezumab (n=107) or placebo (n=110). A significant (p=0.018) change of -0.89±0.11 (galcanezumab) vs -0.53±0.11 (placebo) migraine headache days indicated onset at week 1. Forty-seven per cent of galcanezumab and 25% of placebo patients responding at month 1 maintained response through months 2 and 3. Of non-responders at month 1, 27% on galcanezumab and 20% on placebo responded on months 2 and 3, and 50% of galcanezumab non-responders in months 1 and 2 responded on month 3, vs 24% on placebo. CONCLUSIONS The onset of efficacy of galcanezumab is within 1 week in a majority of patients, and patients receiving galcanezumab are twice more likely to maintain responses than placebo patients. Early non-responders may respond by month 2 or month 3. TRIAL REGISTRATION NUMBER NCT01625988.

Abstract
PURPOSE OF REVIEW This article reviews the preventive therapy of migraine, including indications, strategies for use, and available treatments. RECENT FINDINGS Lifestyle modifications and migraine trigger avoidance are recommended as preventive measures for all individuals with migraine. The decision to recommend additional migraine preventive therapy should consider the frequency of migraine attacks and headaches, extent of migraine-associated disability, frequency of using acute migraine treatments and the responsiveness to such treatments, and patient preferences. Additional therapies include prescription medications, nutraceuticals, neurostimulation, and behavioral therapy. Considering evidence for efficacy and the risk of potential side effects and adverse events, treatments with the most favorable profiles include (in alphabetical order): amitriptyline, beta-blockers (several), biofeedback, candesartan, coenzyme Q10, cognitive-behavioral therapy, magnesium citrate, onabotulinumtoxinA (for chronic migraine only), relaxation therapy, riboflavin, and topiramate. In addition, erenumab, a calcitonin gene-related peptide (CGRP) receptor monoclonal antibody, received approval from the US Food and Drug Administration (FDA) for the prevention of migraine in May 2018. SUMMARY Successful migraine preventive therapy reduces the frequency and burden of attacks while causing limited side effects. Individual treatment recommendations are determined based upon evidence for efficacy, side effect and adverse event profiles, medication interactions, patient comorbidity, costs, and patient preferences. Patients must be counseled on reasonable expectations for their preventive therapy and the importance of adhering to the recommended treatment plan for a period of time that is sufficient to determine outcomes.

Real-world effectiveness of onabotulinumtoxinA treatment for the prevention of headaches in adults with chronic migraine in Australia: a retrospective study. J Headache Pain 2019; 20:81. [PMID: 31307383 PMCID: PMC6734349 DOI: 10.1186/s10194-019-1030-z] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2019] [Accepted: 07/03/2019] [Indexed: 11/10/2022] Open
Abstract
Background OnabotulinumtoxinA (BOTOX®, Allergan plc, Dublin, Ireland) is approved for the preventive treatment of headaches in adult patients with chronic migraine (CM) in Australia by the country’s reimbursement mechanism for medicines, the Pharmaceutical Benefits Scheme (PBS). To our knowledge, this study represents the first focused report evaluating real-world evidence of onabotulinumtoxinA treatment via the PBS in Australian clinics. Methods This study reviewed the medical records of adults with inadequately controlled CM from 7 private neurology practices in Australia who, beginning in March 2014, received PBS-subsidized onabotulinumtoxinA per product labelling for the first time. The primary effectiveness measure was the percentage of patients achieving a response defined by 50% or greater reduction in headache days from baseline after 2 treatment cycles. Additional data were recorded in the case report form when available and included demographics, clinical characteristics, headache severity and frequency, Headache Impact Test (HIT-6) score, medication use, and days missed of work or study at baseline, after 2 treatment cycles, and at last follow-up. Differences in mean changes from baseline were evaluated with a 1-tailed t-test or Pearson’s chi-squared test (p < 0.05). Results The study population included 211 patients with a mean (SD) of 25.2 (5.3) monthly headache days at baseline. In the primary outcome analysis, 74% of patients achieved a response, with a mean (SD) of 10.6 (7.9) headache days after 2 treatment cycles (p < 0.001). Secondary effectiveness outcomes included mean (SD) reductions in HIT-6 score of − 11.7 (9.8) and − 11.8 (12.2) after 2 treatment cycles (p < 0.001) and final follow-up (p < 0.001), respectively, and mean (SD) decreases in days per month of acute pain medication use of − 11.5 (7.6) after 2 treatment cycles (p < 0.001) and − 12.7 (8.1) at final follow-up (p < 0.001). Conclusion This study provides additional clinical evidence for the consistent effectiveness of onabotulinumtoxinA for the treatment of CM in Australia. This effectiveness was made evident by reductions in migraine days, severe headache days, and HIT-6 scores from baseline.

Abstract
Cefaly (Cefaly Technology, Seraing, Belgium) is a device that stimulates the bilateral supraorbital nerve transcutaneously. A previous study in Europe proved that Cefaly was an effective and safe device as a preventive therapy for migraine. However, there have been no studies on this device in Asia. We examined the safety and preventive effect of Cefaly for migraine. One-hundred patients were prospectively collected from four headache units in Japan. The inclusion criteria were as follows: 18–75 years of age, migraine with and without aura, and at least 2 attacks per month. A 4-week baseline period was followed by 12-week treatment period. The primary end point was the change from baseline in the number of migraine days at 12 weeks. The secondary end points include the changes of the number of migraine attacks, all headache days, acute medicine consumption days and headache severity. After treatment, a questionnaire survey on the satisfaction of the treatment was administered to the patients. The Friedmann test was used to assess the changes between baseline period and after treatment, and Mann-Whitney U test was used for the comparison of efficacy between chronic migraine and episodic migraine, with and without prophylactic treatment or medication overuse. After 12 weeks of treatment, Cefaly use significantly decreased the number of migraine days (8.16 vs. 6.84; p = 0.0036). Only three subjects (3.0%) dropped out due to the adverse effects; however, no serious adverse events were observed. The compliance of this study was very high at 90.0%. Furthermore, a significant decrease was observed in the number of migraine attacks (5.33 vs. 3.94; p = 0.0002) and the intake of acute antimigraine drugs (8.75 vs. 7.83; p = 0.0166). Cefaly is considered to be a safe and highly tolerable effective device for Japanese patients. Trial registration: This study was retrospectively registered to UMIN-CTR(UMIN000033333) on 10 July 2018.

Abstract
Unremitting head and neck pain (UHNP) is a commonly encountered phenomenon in Headache Medicine and may be seen in the setting of many well-defined headache types. The prevalence of UHNP is not clear, and establishing the presence of UHNP may require careful questioning at repeated patient visits. The cause of UHNP in some patients may be compression of the lesser and greater occipital nerves by the posterior cervical muscles and their fascial attachments at the occipital ridge with subsequent local perineural inflammation. The resulting pain is typically in the sub-occipital and occipital location, and, via anatomic connections between extracranial and intracranial nerves, may radiate frontally to trigeminal-innervated areas of the head. Migraine-like features of photophobia and nausea may occur with frontal radiation. Occipital allodynia is common, as is spasm of the cervical muscles. Patients with UHNP may comprise a subgroup of Chronic Migraine, as well as of Chronic Tension-Type Headache, New Daily Persistent Headache and Cervicogenic Headache. Centrally acting membrane-stabilizing agents, which are often ineffective for CM, are similarly generally ineffective for UHNP. Extracranially-directed treatments such as occipital nerve blocks, cervical trigger point injections, botulinum toxin and monoclonal antibodies directed at calcitonin gene related peptide, which act primarily in the periphery, may provide more substantial relief for UHNP; additionally, decompression of the occipital nerves from muscular and fascial compression is effective for some patients, and may result in enduring pain relief. Further study is needed to determine the prevalence of UHNP, and to understand the role of occipital nerve compression in UHNP and of occipital nerve decompression surgery in chronic head and neck pain.

Abstract
BACKGROUND Calcitonin gene-related peptide plays an important role in migraine pathophysiology. We evaluated eptinezumab, an intravenous (IV) anti-calcitonin gene-related peptide monoclonal antibody, for the prevention of chronic migraine. OBJECTIVE To determine the safety, tolerability, and effectiveness of four dose levels of eptinezumab and to inform the phase 3 development program. METHODS This was a phase 2b, parallel-group, double-blind, randomized, placebo-controlled, dose-ranging clinical trial. Men and women (N = 616) aged 18-55 years were included if they had a diagnosis of chronic migraine, with onset at age ≤35 years and history of chronic migraine ≥1 year. During the 28-day screening period, patients must have had ≥15 headache days, including ≥8 migraine days, with ≥5 migraine attacks as recorded in the electronic diary. Patients were assigned in a 1:1:1:1:1 ratio to eptinezumab 300, 100, 30, 10 mg or placebo, administered as a single IV infusion. The primary endpoint was the percentage of patients with a ≥75% decrease in monthly migraine days over weeks 1-12 compared with the 28-day screening period. RESULTS The ≥75% migraine responder rates over weeks 1-12 for eptinezumab 300, 100, 30, and 10 mg were 33.3%, 31.4%, 28.2%, and 26.8%, respectively, versus 20.7% for placebo (p = 0.033, 0.072, 0.201, 0.294 vs. placebo). Secondary efficacy endpoints (e.g. ≥50% responder rate, change from baseline in frequency of migraine/headache days, and percentage of severe migraines) had results favoring the three higher eptinezumab doses versus placebo. Eptinezumab was well tolerated and adverse event rates were similar to placebo. CONCLUSIONS The results of this trial demonstrate that eptinezumab appears effective and well-tolerated for the preventive treatment of chronic migraine and justifies the conduct of pivotal phase 3 trials for migraine prevention.

Abstract
Migraine is one of the most common disorders found in everyday clinical practice. Although migraines are not directly life-threatening or permanently disabling, the severity of the pain and symptoms that characterize a migraine attack often prevent normal work and cause difficulties in everyday life. Migraines also affect the patient's family, who often experience stress and depression in response to the patient's condition. Available therapy, used in both acute and chronic treatments, might not provide sufficient improvement. Due to problems like therapy inefficacy, side effects, and intolerance, patients often stop treatments. Recent studies have indicated that drugs that act through calcitonin gene-related peptide (CGRP) can significantly improve migraine therapy. Here, we review results from currently available clinical trials on CGRP receptor antagonists and anti-CGRP monoclonal antibodies.
