Abstract
BACKGROUND Migraine is a leading cause of disability, estimated to affect one-in-ten people in Spain. This study aimed to describe the management of migraine in Spain and identify improvement areas. METHODS Non-interventional, retrospective, cross-sectional cohort study conducted using an electronic medical records database covering visits to public healthcare providers for 3% of the Spanish population. Patients with a migraine diagnosis (ICD-9 346) between 01/2015 and 04/2022 were included, as well as their demographic and clinical characteristics, prescribed migraine treatments and the specialty of the prescribing physicians. RESULTS The database included 61,204 patients diagnosed with migraine. A migraine treatment had been prescribed to 50.6% of patients over the last 24 months (only acute to 69.5%, both acute and preventive to 24.2%, and only preventive to 6.3%). The most frequently prescribed treatments were NSAIDs (56.3%), triptans (44.1%) and analgesics (28.9%). Antidepressants were the most common preventive treatment (prescribed to 17.9% of all treated patients and 58.7% of those treated with a preventive medication), and anti-CGRP monoclonal antibodies the least prescribed (1.7%; 5.7%). In 13.4% of cases, preventive medications were the first treatment: alone in 5.8% of cases and together with an acute medication in 7.6%. A fifth of patients who were initially prescribed with only acute treatment were later prescribed a preventive medication (20.7%). On average, it took 29.4 months for this change to occur. Two-thirds of patients started their preventive treatment in primary care (64.2%). The percentage of patients treated by a neurologist increased with the number of received preventive medications. However, 28.8% of patients who had already been prescribed five or more distinct preventive treatments were not treated by a neurologist. Migraine patients had between 1.2- and 2.2-times higher prevalence of comorbidities than the general population, age-gender adjusted. CONCLUSIONS Our study emphasizes the need for improved management of migraine in Spain to reduce the risk of chronification and improve patient outcomes. More training and coordination across healthcare professionals is necessary to recognize and address risk factors for migraine progression, including multiple associated comorbidities and several lines of treatment, and to provide personalized treatment plans that address the complex nature of the condition.

Abstract
BACKGROUND Many risk factors have been associated with migraine progression, including insufficient and ineffective utilization of migraine medications; however, they have been inadequately explored. This has resulted in suboptimal usage of medications without effective altering of prescribing recommendations for patients, posing a risk for migraine chronification. METHODS Our aim is to conduct a comprehensive review of the available evidence regarding the underuse of migraine medications, both acute and preventive. The term "underuse" includes, but is not limited to: (1) ineffective use of appropriate and inappropriate medication; (2) underutilization; (3) inappropriate timing of usage; and (4) patient dissatisfaction with medication. RESULTS The underuse of both acute and preventive medications has been shown to contribute to the progression of migraine. In terms of acute medication, chronification occurs as a result of insufficient drug use, including failure of the prescriber to select the appropriate type based on pain intensity and disability, patients taking medication too late (more than 60 minutes after the onset or after central sensitization has occurred as evidenced by allodynia), and discontinuation because of lack of effect or intolerable side effects. The underlying cause of inadequate effectiveness of acute medication lies in its inability to halt the propagation of peripheral activation to central sensitization in a timely manner. For oral and injectable preventive migraine medications, insufficient efficacy and intolerable side effects have led to poor adherence and discontinuation with subsequent progression of migraine. The underlying pathophysiology here is rooted in the repetitive stimulation of afferent sensory pain fibers, followed by ascending brainstem pain pathways plus dysfunction of the endogenous descending brainstem pain inhibitory pathway. Although anti-calcitonin gene-related peptide (CGRP) medications partially address pain caused by the above factors, including decreased efficacy and tolerability from conventional therapy, some patients do not respond well to this treatment. Research suggests that initiating preventive anti-CGRP treatment at an early stage (during low frequency episodic migraine attacks) is more beneficial than commencing it during high frequency episodic attacks or when chronic migraine has begun. CONCLUSIONS The term "medication underuse" is underrecognized, but it holds significant importance. Optimal usage of acute care and preventive migraine medications could potentially prevent migraine chronification and improve the treatment of migraine attacks.

Abstract
INTRODUCTION Migraine is a chronic neurological disorder causing severe pain and disability in more than a billion people worldwide. Ideal treatment should provide long-term efficacy with minimal side effects. Previous studies indicate that remote electrical neuromodulation (REN) is an efficacious and safe treatment option for the acute treatment of migraine in clinical practice. This study examined long-term safety, utilization, and efficacy of REN during 12 consecutive usage months. METHODS Data from patients with migraine across the USA using REN to treat their migraine attacks were electronically collected from the Nerivio® device. All patients who used REN during 12 consecutive months were included, and data were compared across months. Safety was assessed by the number and type of adverse events. Utilization was measured by the number of monthly treatments. Efficacy was evaluated as consistent change in headache pain intensity, functional disability, and disappearance of associated symptoms from baseline to 2 h post treatment. RESULTS Data were analyzed from 409 people living with migraine who treated with REN for 12 consecutive months, performing a total of 39,531 treatments. The incidence of device-related adverse events (dAEs) was 1.96% (8/409), including two negligible (0.49%), five mild (1.22%), one moderate (0.24%), and no severe events. All patients continued treatment with REN despite dAEs. One-year average monthly utilization was 8.05 treatments (SD 1.15). Month-to-month utilization did not change during 12 months of consecutive use [F(4.895, 1997.204) = 2.014, p = 0.075, repeated-measures ANOVA]. One-year average efficacy showed 74.1% of users reported consistent 2-h pain relief, and 26.0% reported consistent pain freedom. Month-to-month pain relief and pain freedom did not change during 12 months of consecutive use [F(11, 1069) = 0.55, p = 0.873 and F(11, 1295) = 0.69, p = 0.750 respectively; generalized linear mixed model analysis]. CONCLUSION REN is a safe and well-tolerated acute migraine treatment, with stable efficacy and utilization over 1 year, making it an advantageous non-drug option for the long-term management of this chronic disease. TRIAL REGISTRATION NUMBER NCT05760638.

Abstract
OBJECTIVE This study aimed to ascertain whether level of optimization of acute treatment of migraine is related to work productivity across the spectrum of migraine. METHODS Data were from the Chronic Migraine Epidemiology and Outcomes (CaMEO) Study, an internet-based longitudinal survey. Respondents with migraine who reported full-time employment and use of ≥1 acute prescription medication for migraine were included. We determined relationships among lost productive time (LPT; measured with the Migraine Disability Assessment Scale), acute treatment optimization (Migraine Treatment Optimization Questionnaire- ), and monthly headache days (MHDs). RESULTS There was a direct relationship between LPT and MHD category. Greater acute treatment optimization was associated with lower total LPT, less absenteeism, and less presenteeism within each MHD category. CONCLUSIONS Optimizing acute treatment for migraine may reduce LPT in people with migraine and reduce indirect costs.

Abstract
OBJECTIVE To characterize treatment decision-making processes and formalize consensus regarding key factors headache specialists consider in treatment decisions for patients with migraine, considering novel therapies. BACKGROUND Migraine therapies have long been subject to binary classification, acute versus preventive, due to limitations of available drugs. The emergence of novel therapies that can be used more flexibly creates an opportunity to rethink this binary classification. To determine the role of these novel therapies in treatment, it is critical to understand whether existing guidelines reflect clinical practice and to establish consensus around factors driving management. METHODS A three-round modified Delphi process was conducted with migraine clinical experts. Round 1 consisted of an online questionnaire; Round 2 involved an online discussion of aggregated Round 1 results; and Round 3 allowed participants to revise Round 1 responses, incorporating Round 2 insights. Questions elicited likelihood ratings (0 = highly unlikely to 100 = highly likely), rankings, and estimates on treatment decision-making. RESULTS Nineteen experts completed three Delphi rounds. Experts strongly agreed on definitions for "acute" (median = 100, inter-quartile range [IQR] = 5) and "preventive" treatment (median = 90, IQR = 15), but noted a need for treatment customization for patients (median = 100, IQR = 6). Experts noted certain aspects of guidelines may no longer apply based on established tolerability and efficacy of newer acute and preventive agents (median = 91, IQR = 17). Further, experts agreed on a treatment category referred to as "situational prevention" (or "short-term prevention") for patients with reliable and predictable migraine triggers (median = 100, IQR = 10) or time-limited periods when headache avoidance is important (median = 100, IQR = 12). CONCLUSIONS Using the modified Delphi method, a panel of migraine experts identified the importance of customizing treatment for people with migraine and the utility of "situational prevention," given the ability of new treatment options to meet this need and the potential to clinically identify patients and time periods when this approach would add value.

Mechanisms of mindfulness in patients with migraine: Results of a qualitative study. Headache 2023; 63:390-409.

Abstract
OBJECTIVE To understand the mechanisms of mindfulness' impact on migraine. BACKGROUND Promising mindfulness research demonstrates potential benefit in migraine, but no data-driven model exists from the lived experiences of patients that explains the mechanisms of mindfulness in migraine. METHODS Semi-structured qualitative interviews were conducted with adults with migraine who participated in two mindfulness-based stress reduction (MBSR) clinical trials (n = 43). Interviews were audio-recorded, transcribed, and summarized into a framework matrix with development of a master codebook. Constructivist grounded theory approach was used to identify themes/subthemes. RESULTS Participants who learned mindfulness techniques through MBSR experienced altered pain perception, altered response to migraine attacks and disease, increased awareness of external and internal experiences, improved overall well-being, and group benefits. Mindfulness resulted in earlier stress-body awareness and increased interoceptive awareness resulting in earlier attack recognition, leading to earlier and more effective management. Interictal factors of self-blame, guilt, and stigma decreased while migraine acceptance, hope, empowerment, self-efficacy, and self-compassion increased. Improved emotion regulation resulted in decreased fear of migraine, pain catastrophizing, anticipatory anxiety, and pain reactivity. Although taught as prevention, mindfulness was used both acutely and prophylactically. We created a conceptual model hypothesizing that MBSR skills led to an infusion of mindfulness in daily life, resulting in altered pain perception and experience, ultimately leading to improvement in overall well-being, which may positively feed back to the infusion of mindfulness in daily life. The therapeutic benefit of learning mindfulness in a group setting may moderate these effects. CONCLUSIONS This study identified several new potential mechanisms of mindfulness' effect on migraine. After learning MBSR skills, participants reported altered pain and migraine perception and experiences. Increased stress-body and interoceptive awareness resulted in earlier migraine awareness and treatment. Mindfulness may target important interictal factors that affect disease burden such as fear of migraine, pain catastrophizing, and anticipatory anxiety. This is the first data-driven study to help elucidate the mechanisms of mindfulness on migraine from patient voices and can help direct future research endeavors.

Abstract
BACKGROUND: Migraine is the second most common cause of disability worldwide. Understanding the relationship between migraine and employment status is critical for policymakers, as disability-related unemployment is associated with eligibility for private or governmental disability insurance payments and other associated support for those unable to work because of disability. OBJECTIVE: To assess the association between migraine frequency and selfreported employment status and overall disability in a US representative survey. METHODS: Using data from the 2019 National Health and Wellness Survey (NHWS) (Kantar Health), adults in the United States (aged 18-65 years) reporting at least 1 migraine day in the past 30 days were categorized by headache frequency: low-frequency episodic migraine (LFEM) (≤4 days/month), moderate-frequency EM (MFEM) (5-9 days/month), high-frequency EM (HFEM) (10-14 days/month), or chronic migraine (CM) (≥15 days/month). A control group of adults without migraine with similar baseline characteristics was identified by propensity score matching. Disability-related unemployment was defined as participants responding "short-term disability" or "long-term disability" to occupational status on the NHWS. The frequency of short- or long-term disability was then evaluated across headache frequency groups. In addition, participants were asked to assess migraine-related disability via the Migraine Disability questionnaire (MIDAS). RESULTS: A total of 1,962 respondents with LFEM, 987 with MFEM, 554 with HFEM, and 926 with CM were included in this analysis, along with 4,429 matched controls. Headache frequency was associated both with increased MIDAS score and with employment disability (P < 0.001); 12.3% (n = 114 of 926) of participants with CM reported employment disability, as did 4.4% (n = 86 of 1,962) of the LFEM group and 6.9% (n = 306 of 4,429) of matched controls. There was considerable discordance between the proportion of participants classified as disabled via MIDAS vs those reporting employment-related disability. CONCLUSIONS: More frequent migraine headaches are associated with a higher likelihood of self-reported short- and long-term employment disability and overall migraine-related disability, suggesting that health and economic policymakers must seek ways to maximize the employment opportunities for people living with migraine that may benefit from novel preventive treatments.

Abstract
BACKGROUND This post-hoc analysis from three phase 3 treatment trials of rimegepant 75 mg - an oral small molecule calcitonin gene-related peptide receptor antagonist for acute and preventive treatment of migraine - assessed efficacy in adults with migraine based on triptan treatment experience. METHODS Participants were assigned to one of four groups based on triptan treatment experience: insufficient response (e.g. lack of efficacy and/or poor tolerability) to 1 triptan, insufficient response to ≥2 triptans, current triptan users, and triptan-naïve participants. The co-primary efficacy endpoints were pain freedom and most bothersome symptom freedom at two hours postdose. RESULTS In the three trials (N = 3507; rimegepant n = 1749, placebo n = 1758), 1235 (35.2%) participants had a history of insufficient response to 1 triptan (n = 910 [25.9%]) or ≥2 triptans (n = 325 [9.3%]), and 2272 (64.8%) had no history of insufficient response to triptans (current use = 595 [17.0%], naïve = 1677 [47.8%]). Rimegepant was effective on the co-primary endpoints in all subgroups (p ≤ 0.013), except for freedom from the most bothersome symptom in the triptan-naïve group (p = 0.06). No differences on co-primary endpoints were found in pairwise comparisons of rimegepant-treated participants. CONCLUSIONS Rimegepant was effective for the acute treatment of migraine in adults with a history of insufficient response to 1 or ≥2 triptans and in current triptan users. Efficacy on co-primary endpoints did not differ based on the number of insufficient triptan responses.Trial registration: Clinicaltrials.gov: NCT03235479, NCT03237845, NCT03461757.

Abstract
OBJECTIVE To describe the pattern of triptan use by gender in Tuscany, Italy, focusing on special user populations in which evidence on triptan safety is still not conclusive. BACKGROUND Growing evidence supports the role of gender differences in migraine pathophysiology and treatment. However, gender impact on triptan real-word utilization has been poorly investigated. METHODS A retrospective, descriptive, cohort study was performed using the population-based Administrative Healthcare Database of Tuscany region (Italy). Subjects registered in the database on the January 1 of each year between 2008 and 2018 were identified. New users (NU) of triptans (ATC:N02CC*) were patients with one or more triptan dispensation during the year of interest and none in the past. Age, cardiovascular comorbidities representing an absolute or a possible contraindication to triptan utilization, concomitant serotonergic medications, and pattern of triptan use during 1-year follow-up were described by gender. RESULTS A total of 86,109 patients who received one or more triptan dispensing were identified. Of 64,672 NU (men = 17,039; women = 47,633), 10.2% (6823/64,672) were aged >65 years, who were mostly women (n = 4613). Among NU, men and women with absolute cardiovascular contraindications were 4.3% (740/17,039) and 2.1% (1022/47,633), respectively, while those concomitantly taking serotonergic medications were 17.2% (267/1549) and 21.9% (949/4330), respectively (949/4330). Regular users (two or more dispensing with ≥3 months between first and last observed dispensing) accounted for 26.4% of women (12,597/47,633) and 19.11% of men (3250/17,039); frequent users (≥15 dosage units/month during ≥3 consecutive months) were overall 0.1% (94/64,672) and 62.0% (58/94) of them concomitantly received serotonergic medications. CONCLUSION Considering gender differences in triptan use highlighted here, large scale observational studies are warranted to better define what populations are safe to use triptans and whether it is appropriate to tighten or relax certain recommendations on triptan use. In the meantime, any suspected adverse drug reaction observed in the special user populations highlighted in this study should be promptly reported.

The Effectiveness of Mindful Hypnotherapy on Psychological Inflexibility, Pain Acceptance, Headache Disability and Intensity in Females with Chronic Migraine Headache: A Randomized Clinical Trial. Life (Basel) 2023; 13:life13010131.

Abstract
This study was a randomized controlled design and examined the feasibility and effectiveness of mindful hypnotherapy on psychological inflexibility, pain acceptance, headache disability, and headache intensity in patients with chronic migraine headaches. The sample consisted of 38 females with chronic migraine who were randomly assigned to mindful hypnotherapy and medical treatment as usual groups. Psychological inflexibility pain scale (PIPS), chronic pain acceptance questionnaire-revised (CPAQ-R), headache disability inventory (HDI), diary scale for headache, and short-form McGill pain questionnaire 2 (SF-MPQ-2) were administered at baseline and post-treatment in both groups. The psychological inflexibility mean (SD) score was 81.00 (12.15) at baseline, which significantly decreased to 53.28 (17.06) after the intervention (p < 0.001). Additionally, the mean (SD) score of the pain acceptance was 46.44 (11.16), which significantly increased to 73.61 (15.65) in post-intervention (p < 0.001). Furthermore, the mean (SD) score of headache disability was 73.55 (19.48), which significantly decreased to 23.33 (19.88) in post-intervention (p < 0.001). Finally, headache intensity was 7.33 (0.98) and 5.78 (1.83), which significantly decreased to 2.77 (2.04), and 1.38 (1.48) after the intervention based on the Diary Scale for Headache and McGill Pain Questionnaire (SF-MPQ-2), respectively (p < 0.001). In conclusion, the results show that mindful hypnotherapy is a feasible and effective treatment for chronic migraine.

Two-year efficacy and safety of erenumab in participants with episodic migraine and 2-4 prior preventive treatment failures: results from the LIBERTY study. J Neurol Neurosurg Psychiatry 2022; 93:254-262. [PMID: 34845002 PMCID: PMC8862066 DOI: 10.1136/jnnp-2021-327480] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Accepted: 11/07/2021] [Indexed: 11/25/2022]
Abstract
OBJECTIVE To evaluate individual and group long-term efficacy and safety of erenumab in individuals with episodic migraine (EM) for whom 2-4 prior preventatives had failed. METHODS Participants completing the 12-week double-blind treatment phase (DBTP) of the LIBERTY study could continue into an open-label extension phase (OLEP) receiving erenumab 140 mg monthly for up to 3 years. Main outcomes assessed at week 112 were: ≥50%, ≥75% and 100% reduction in monthly migraine days (MMD) as group responder rate and individual responder rates, MMD change from baseline, safety and tolerability. RESULTS Overall 240/246 (97.6%) entered the OLEP (118 continuing erenumab, 122 switching from placebo). In total 181/240 (75.4%) reached 112 weeks, 24.6% discontinued, mainly due to lack of efficacy (44.0%), participant decision (37.0%) and adverse events (AEs; 12.0%). The ≥50% responder rate was 57.2% (99/173) at 112 weeks. Of ≥50% responders at the end of the DBTP, 36/52 (69.2%) remained responders at ≥50% and 22/52 (42.3%) at >80% of visits. Of the non-responders at the end of the DBTP, 60/185 (32.4%) converted to ≥50% responders in at least half the visits and 24/185 (13.0%) converted to ≥50% responders in >80% of visits. Change from baseline at 112 weeks in mean (SD) MMD was -4.2 (5.0) days. Common AEs (≥10%) were nasopharyngitis, influenza and back pain. CONCLUSIONS Efficacy was sustained over 112 weeks in individuals with difficult-to-treat EM for whom 2-4 prior migraine preventives had failed. Erenumab treatment was safe and well tolerated, in-line with previous studies. TRIAL REGISTRATION NUMBER NCT03096834.

Abstract
INTRODUCTION Ubrogepant is a calcitonin gene-related peptide receptor antagonist indicated for acute treatment of migraine that can be used to treat breakthrough attacks in individuals taking preventive treatment for migraine. We evaluated the impact of preventive medication use on the efficacy and safety of ubrogepant for the acute treatment of migraine. METHODS This was an analysis of pooled efficacy data from the ACHIEVE I and ACHIEVE II phase 3 trials, in which efficacy of ubrogepant was assessed at 2 h after taking study medication for pain freedom, absence of most bothersome symptom (MBS), and pain relief. In addition, a long-term safety (LTS) extension trial was completed where safety was assessed on the basis of incidence and severity of treatment-emergent adverse events (TEAEs). Outcomes were compared between participants with or without prior (within 6 months) preventive medication use (anticonvulsants, beta blockers, antidepressants, or onabotulinumtoxinA). For efficacy analyses, data were pooled across ACHIEVE trials for the 50 mg and placebo groups; for safety analyses, data for all dose groups (50 mg and 100 mg) in the LTS trial were pooled. RESULTS Preventive treatments were used by 417 of 2247 (18.6%) participants analyzed in the ACHIEVE trials and by 143 of 813 (17.5%) participants in the LTS trial. Responder rates for all outcomes were similar between participants with or without preventive treatment within each dose group (p > 0.05). No significant differences were noted across the different preventive medications. Rates and types of TEAEs were similar between participants with or without preventive treatment. No serious treatment-related adverse events were reported. CONCLUSION Efficacy and safety of ubrogepant for the acute treatment of migraine were similar between participants with or without prior or current use of concomitant preventive medication. TRIAL REGISTRATION ClinicalTrials.gov identifiers: NCT02828020 (ACHIEVE I), NCT02867709 (ACHIEVE II), and NCT02873221 (long-term safety trial).

Cognitive Behavioral Therapy for Migraine Headache: A Systematic Review and Meta-Analysis. MEDICINA (KAUNAS, LITHUANIA) 2021; 58:medicina58010044. [PMID: 35056352 PMCID: PMC8777662 DOI: 10.3390/medicina58010044] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/16/2021] [Revised: 12/03/2021] [Accepted: 12/20/2021] [Indexed: 12/23/2022]
Abstract
Background and Objectives: Migraine headaches are chronic neurological diseases that reduce the quality of life by causing severe headaches and autonomic nervous system dysfunction, such as facial flushing, nasal stuffiness, and sweating. Their major treatment methods include medication and cognitive behavioral therapy (CBT). CBT has been used for pain treatment and various psychogenic neurological diseases by reducing pain, disability, and emotional disorders caused by symptoms of mental illness and improving the understanding of mental health. This study aimed to evaluate the effectiveness and safety of CBT in treating migraines. Materials and Methods: Seven electronic databases were searched from the date of inception to December 2020. Randomized controlled studies (RCTs) using CBT as an intervention for migraine were included. The primary outcome of this study was to determine the frequency of migraines and the intensity of migraines on Visual Analog Scale (VAS), the frequency of drug use, Migraine Disability Assessment (MIDAS), and Headache Impact Test (HIT-6) index. The two authors independently conducted the data extraction and quality assessment of the included RCTs, and conducted meta-analysis with RevMan V.5.4. Results: Among the 373 studies, 11 RCTs were included in this systematic review. Seven out of the 11 RCTs were conducted in the USA, and four were conducted in the UK, Germany, Iran, and Italy, respectively. Headache frequency and MIDAS scores were statistically significant reduced. In the subgroup analysis, headache strength was significantly reduced. Two of the included studies reported adverse effects, including worsening of migraine intensity and frequency, respiratory symptoms, and vivid memory of a traumatic event. Conclusions: CBT for migraine effectively reduced headache frequency and MIDAS score in meta-analysis and headache intensity subgroup analysis, with few adverse events. Additional RCTs with CBT for migraine headaches are needed for a more accurate analysis.

Headache 2021; 61:1214-1226. [PMID: 34363701 PMCID: PMC9292844 DOI: 10.1111/head.14184] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2021] [Revised: 05/21/2021] [Accepted: 06/02/2021] [Indexed: 12/12/2022]
Abstract
Objective To report the safety, tolerability, exploratory efficacy, and patient acceptability of INP104 for the acute treatment of migraine from the Phase 3 STOP 301 trial. Background Dihydroergotamine (DHE) has long been used to treat migraine, but intravenous administration is invasive, frequently associated with adverse events (AEs), and not suitable for at‐home administration. INP104 is an investigational drug device that delivers DHE mesylate to the upper nasal space using a Precision Olfactory Delivery technology and was developed to overcome the shortcomings of available DHE products. Methods STOP 301 was an open‐label, 24‐week safety study, with a 28‐week extension period. After a 28‐day screening period where patients used their “best usual care” to treat migraine attacks, patients were given INP104 (1.45 mg) to self‐administer nasally with self‐recognized attacks. The primary objective of this study was to assess safety and tolerability, with a specific focus on nasal mucosa and olfactory function. Exploratory objectives included efficacy assessments of migraine measures and a patient acceptability questionnaire. Results A total of 360 patients entered the 24‐week treatment period, with 354 patients dosing at least once. INP104‐related treatment‐emergent AEs were reported by 36.7% (130/354) of patients, and 6.8% (24/354) discontinued treatment due to AEs over 24 weeks. No new safety signals were observed following delivery to the upper nasal space. Pain freedom, the most bothersome symptom freedom, and pain relief at 2 h post‐INP104 were self‐reported by 38.0% (126/332), 52.1% (173/332), and 66.3% (167/252) of patients, respectively. A low recurrence rate at 24 and 48 h was observed (7.1% [9/126] and 14.3% [18/126], respectively). Most patients found INP104 easy to use and preferred it over their current therapy. Conclusions INP104 has the potential to deliver rapid symptom relief, without injection, that is well tolerated and suitable for outpatient use. Results suggest INP104 may be a promising treatment for patients with migraine.

Abstract
OBJECTIVE To better characterize the ways that migraine affects multiple domains of life. BACKGROUND Further understanding of migraine burden is needed. METHODS Adults with migraine randomized to mindfulness-based stress reduction or headache education arms (n = 81) in two separate randomized clinical trials participated in semistructured in-person qualitative interviews conducted after the interventions. Interviews queried participants on migraine impact on life and were audio-recorded, transcribed, and summarized into a framework matrix. A master codebook was created until meaning saturation was reached and magnitude coding established code frequency. Themes and subthemes were identified using a constructivist grounded theory approach. RESULTS Despite most participants being treated with acute and/or prophylactic medications, 90% (73/81) reported migraine had a negative impact on overall life, with 68% (55/81) endorsing specific domains of life impacted and 52% (42/81) describing impact on emotional health. Six main themes of migraine impact emerged: (1) global negative impact on overall life; (2) impact on emotional health; (3) impact on cognitive function; (4) impact on specific domains of life (work/career, family, social); (5) fear and avoidance (pain catastrophizing and anticipatory anxiety); and (6) internalized and externalized stigma. Participants reported how migraine (a) controls life, (b) makes life difficult, and (c) causes disability during attacks, with participants (d) experiencing a lack of control and/or (e) attempting to push through despite migraine. Emotional health was affected through (a) isolation, (b) anxiety, (c) frustration/anger, (d) guilt, (e) mood changes/irritability, and (f) depression/hopelessness. Cognitive function was affected through concentration and communication difficulties. CONCLUSIONS Migraine has a global negative impact on overall life, cognitive and emotional health, work, family, and social life. Migraine contributes to isolation, frustration, guilt, fear, avoidance behavior, and stigma. A greater understanding of the deep burden of this chronic neurological disease is needed to effectively target and treat what is most important to those living with migraine.

Abstract
The acute treatment of migraine requires effective drugs that are well tolerated and provide rapid and consistent pain relief. Oral tablets are the most commonly used acute treatment for migraine; however, their effectiveness is limited by the rate of gastrointestinal (GI) tract absorption and first-pass hepatic metabolism, and they may not be ideal for patients experiencing GI motility issues. Nasal delivery is an attractive alternative route as it may circumvent GI tract absorption, avoid first-pass metabolism in the liver, and potentially reduce the frequency of GI adverse events. The large surface area and high vascularity within the nose may permit rapid absorption of therapeutics into the systemic circulation, allowing for rapid onset of action. However, the site of drug deposition (upper versus lower nasal cavity) may influence drug pharmacokinetics. Most approved nasal migraine therapies target the lower nasal space where the epithelium is less permeable, and they may be quickly cleared away due to increased ciliary function or dripping from the nose or swallowing, resulting in variable absorption and limited bioavailability. Together with its abundant vascularization, relative mucosal thickness stability, and low clearance rates, the upper nasal space harnesses the benefits of nasal delivery to potentially maximize drug efficacy.

Abstract
PURPOSE OF REVIEW Migraine is a disabling disease of attacks of moderate to severe pain with associated symptoms. Every person with migraine requires treatment for acute attacks. Treatments can range from behavioral management and nonspecific medications to migraine-specific medications and neuromodulation. For many with migraine, having a combination of tools allows for effective treatment of all types of attacks. RECENT FINDINGS Over the past several years, four neuromodulation devices have been cleared by the US Food and Drug Administration (FDA) for treatment of acute migraine, and three medications with novel mechanisms of action have been FDA approved. They add to the arsenal available to people with migraine and focus on migraine-specific pathways to allow for precise care with fewer side effects. SUMMARY This article discusses acute migraine therapy, focusing on best-level evidence.

Abstract
BACKGROUND: Migraine is a common neurological disease that can have a substantial impact on patients' lives and on society. Erenumab, a fully human monoclonal antibody that targets the calcitonin gene-related peptide receptor, was specifically developed for migraine prevention. The efficacy of erenumab has been established in several clinical trials; however, the real-world comparative effectiveness of erenumab has not been fully investigated. OBJECTIVE: To evaluate the real-world impact of erenumab and onabotulinumtoxinA on acute medication usage and health care resource utilization (HCRU) among patients with migraine in the United States. METHODS: This retrospective US claims analysis (Optum's deidentified Clinformatics Data Mart Database) evaluated patients aged at least 18 years diagnosed with migraine who initiated erenumab or onabotulinumtoxinA between May 1, 2018, and September 30, 2019 (index date: first erenumab/onabotulinumtoxinA claim). Cohorts were matched 1:1 using the propensity score (PS) method (greedy match with caliper = 0.1). Stratification was performed based on gender, chronic migraine without aura diagnosis, onabotulinumtoxinA use, and acute/preventive drug use. The impact of erenumab and onabotulinumtoxinA on acute medication usage and HCRU was assessed in the 6-month post-index period. An exploratory analysis assessed the impact of erenumab and onabotulinumtoxinA on a composite endpoint of: (1) outpatient visit with a migraine diagnosis and associated acute medication claim, (2) hospital admission with a primary migraine diagnosis, or (3) emergency department visit with a primary migraine diagnosis. PS-matched data were used for comparative analyses; logistic regression with covariate adjustment was used for dichotomous variables, and a negative binomial model was used for count variables, with odds ratios or rate ratios (RRs) and 95% CIs calculated. RESULTS: Following stratified PS matching, 1,338 patients were included in both cohorts. At 6 months, the adjusted average number of claims per person for any acute medication was significantly lower in the erenumab cohort (1.13 vs 1.29 in the onabotulinumtoxinA cohort; RR = 0.88; 95% CI = 0.80-0.96; P = 0.0069), although the difference in the number of claims for triptans and barbiturates was statistically nonsignificant. The adjusted average number of all-cause and migraine-specific visits per person to health care providers was generally lower in the erenumab cohort compared with the onabotulinumtoxinA cohort. Patients in the erenumab cohort had a significantly lower number of composite events (0.44 vs 0.69 in the onabotulinumtoxinA cohort; RR = 0.63; 95% CI = 0.56-0.71; P < 0.0001). Similarly, the adjusted proportion of patients with any of the 3 composite events was lower in the erenumab cohort (31.7% vs 44.3% in the onabotulinumtoxinA cohort; OR = 0.59; 95% CI = 0.49-0.70; P < 0.0001). CONCLUSIONS: In this retrospective claims analysis study, erenumab significantly reduced acute medication usage (opioids and nonsteroidal anti-inflammatory drugs; any acute medication when analyzed together) and HCRU to a greater extent than onabotulinumtoxinA.

Impact of monthly headache days on anxiety, depression and disability in migraine patients: results from the Spanish Atlas. Sci Rep 2021; 11:8286.

Abstract
Identifying highly disabled patients or at high risk of psychiatric comorbidity is crucial for migraine management. The burden of migraine increases with headache frequency, but the number of headache days (HDs) per month after which disability becomes severe or the risk of anxiety and depression is higher has not been established. Here, we estimate the number of HDs per month after which migraine is associated with higher risk of anxiety and depression, severe disability and lower quality of life. We analysed 468 migraine patients (mean age 36.8 ± 10.7; 90.2% female), of whom 38.5% had ≥ 15 HDs per month. Our results show a positive linear correlation between the number of HDs per month and the risk of anxiety (r = 0.273; p < 0.001), depression (r = 0.337; p < 0.001) and severe disability (r = 0.519; p < 0.001). The risk of anxiety is higher in patients having ≥ 3HDs per month, and those with ≥ 19HDs per month are at risk of depression. Moreover, patients suffering ≥ 10HDs per month have very severe disability. Our results suggest that migraine patients with ≥ 10HDs per month are very disabled and also that those with ≥ 3HDs per month should be screened for anxiety.

A non-convulsant delta-opioid receptor agonist, KNT-127, reduces cortical spreading depression and nitroglycerin-induced allodynia. Headache 2021; 61:170-178. [PMID: 33326598 PMCID: PMC8082730 DOI: 10.1111/head.14019] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2020] [Revised: 10/08/2020] [Accepted: 10/09/2020] [Indexed: 12/12/2022]
Abstract
OBJECTIVE The aim of this study was to determine if the non-convulsant delta-opioid receptor (DOR) agonist, KNT-127, could inhibit migraine-associated endpoints. BACKGROUND The DOR has been identified as a therapeutic target for migraine. However, the development of delta agonists is limited as some ligands have seizurogenic properties, which may be related to their ability to induce receptor internalization. While both pro- and non-convulsant delta agonists can reduce migraine-associated allodynia, only the proconvulsant agonist, SNC80, has been shown to decrease cortical spreading depression (CSD). It is unclear if the ability of delta agonists to modulate cortical activity is related to the same signaling mechanisms that produce proconvulsant effects. METHODS The effects of the non-convulsant delta agonist, KNT-127, were examined. Repetitive CSD was induced in female C57BL6/J (n = 6/group) mice by continuous application of KCl and the effect of KNT-127/vehicle (Veh) on both local field potentials and optical intrinsic signals was determined. To assess the effect of KNT-127 on established chronic migraine-associated pain, male and female C57BL6/J mice were treated with nitroglycerin (NTG; 10 mg/kg, ip) every other day for 9 days and tested with KNT-127 (5 mg/kg, sc) or Veh on day 10 (n = 6/group). DOR-enhanced green fluorescent protein mice (n = 4/group) were used to confirm the internalization properties of KNT-127 in the trigeminal ganglia, trigeminal nucleus caudalis, and somatosensory cortex. RESULTS KNT-127 inhibited CSD events (t(10) = 3.570, p = 0.0051). In addition, this delta agonist also reversed established cephalic allodynia in the NTG model of chronic migraine (F(1, 20) = 12.80, p < 0.01). Furthermore, KNT-127 caused limited internalization of DOR in key migraine processing regions. CONCLUSIONS This study shows that the antimigraine effects of DOR agonists can be separated from their proconvulsant effects. This data provides valuable information for the continued development of delta agonists for the treatment of migraine.

Abstract
OBJECTIVE Remote electrical neuromodulation (REN) is a nonpharmacological acute migraine treatment that stimulates upper-arm peripheral nerves. The aim of this investigation was to evaluate the effectiveness and safety of REN for acute treatment of migraine in a real-world setting. METHODS Real-world data were collected from patients who were using REN (Nerivio®, Theranica Bio-Electronics Ltd., Israel) between October 1, 2019, and March 31, 2020. Patients recorded their symptoms at baseline, two hours, and 24 hours post-treatment. Patients were stratified based on the type of visit and provider; in-person visits with headache specialists (HS group) or virtual visits with nonheadache specialists (NHS group). Efficacy outcome focused on intra-individual consistency of response across multiple attacks. RESULTS We found that 58.9% (662/1,123) of the patients in the HS group and 74.2% (23/31) of the patients in the NHS group experienced pain relief at two hours in at least 50% of their treated attacks and 20.0% (268/1,339) of the patients in the HS group and 35.6% (16/45) of the patients in the NHS group experienced pain freedom at two hours in at least 50% of their treated attacks. The effects of REN on associated symptoms and improvement in function were also consistent in both groups. The incidence of device-related adverse events was very low (0.5%). CONCLUSIONS Real-world data confirm that REN results in meaningful clinical benefits with minimal side effects. REN may provide an effective drug-free treatment option for achieving consistent relief from migraine symptoms and may reduce the use of acute medications.

Abstract
OBJECTIVES To quantify the social burden among Japanese migraine patients in the context of currently available migraine treatments, by comparison with non-migraine controls, and comparison of migraine patients currently taking prescription medication versus not taking prescription medication. DESIGN Cross-sectional analysis. SETTING Data from the population-based online self-administered Japan National Health and Wellness Survey (NHWS) 2017. PARTICIPANTS Respondents to the NHWS (n=30 001) were ≥18 years. Migraine patients were respondents with self-reported experience and physician diagnosis of migraine. Non-migraine controls reported no migraine experience. Migraine patients were subgrouped into currently taking prescription medication for migraine (Rx) and currently not taking prescription medication (non-Rx). METHODS One-way analysis of variance tests were performed to compare health-related quality of life (HRQoL), work productivity and activity impairment and healthcare resource utilisation between migraine patients and matched non-migraine controls selected by 1:1 propensity score matching. Generalised linear models were used to compare outcomes and migraine related characteristics between Rx and non-Rx. RESULTS Compared with matched controls, migraine patients (n=1265) had significantly lower HRQoL in terms of lower Physical Component Summary (48.36 vs 51.29, p<0.001), Mental Component Summary (44.65 vs 48.31, p<0.001), Role/Social Component Summary (41.78 vs 46.18, p<0.001) and mean EuroQol 5-Dimension index (0.77 vs 0.86, p<0.001) scores. Migraine patients experienced significantly higher absenteeism (6.95% vs 3.07%, p<0.001), presenteeism (32.73% vs 18.94%, p<0.001), work productivity loss (34.82% vs 20.03%, p<0.001) and daily activity impairment (35.70% vs 22.04%, p<0.001) and visited healthcare professionals more often (8.38 vs 4.57, p<0.001) than controls. No significant differences in these outcomes were found when comparing Rx (n=587) and non-Rx (n=678) patients. CONCLUSIONS There is an unmet need for improved HRQoL and work productivity in Japanese migraine patients despite the currently available prescription medications, which are important factors to consider for future development of migraine therapies.

Abstract
INTRODUCTION Remote electrical neuromodulation (REN) is a novel acute treatment of migraine. Upper arm peripheral nerves are stimulated to induce conditioned pain modulation (CPM)-an endogenous analgesic mechanism in which conditioning stimulation inhibits pain in remote body regions. The REN device (Nerivio®, Theranica Bio-Electronics LTD., Israel) is FDA-authorized for acute treatment of migraine in adults who do not have chronic migraine. The current study assessed the consistency of response over multiple migraine attacks in people with chronic migraine who are typically characterized with severe pain intensity, high disability, and less robust response to triptans. METHODS This was an open-label, single-arm, dual-center study conducted on adults with chronic migraine. Participants underwent a 4-week treatment phase in which they treated their migraine headaches with the device for 45 min within 1 h of attack onset. Pain levels were recorded at baseline, 2 h, and 24 h post-treatment. Efficacy outcomes (pain relief and pain-free responses at 2 h, sustained pain relief and sustained pain-free responses at 24 h) focused on intra-individual consistency of response across multiple attacks, which was defined as response in at least 50% of the treatments. RESULTS Forty-two participants were enrolled, and 38 participants were evaluable for analyses; 73.7% (28/38) achieved pain relief at 2 h, 26.3% (10/38) were pain-free at 2 h, 84.4% (27/32) had sustained pain relief response at 24 h and 45.0% (9/20) had sustained pain relief response at 24 h in at least 50% of their treated attacks. The effects of REN on associated symptoms and improvement in function were also consistent. The incidence of device-related adverse events was low (1.8%). CONCLUSIONS REN used for a series of migraine attacks was effective and well tolerated across attacks. REN may offer a safe and effective non-pharmacological alternative for acute treatment in patients with chronic migraine. TRIAL REGISTRATION ClinicalTrials.gov identifier, NCT04161807.

Abstract
Introduction: Migraine is the second leading cause of disability worldwide, yet many patients are unable to tolerate, benefit from, or afford pharmacological treatment options. Non-pharmacological migraine therapies exist, especially to reduce opioid use, which represents a significant unmet need. Mindfulness-based interventions (MBI) have potential as a non-pharmacological treatment for migraine, primarily through the development of flexible attentional capacity across sensory, cognitive, and emotional experiences.Areas covered: The authors review efficacy and potential mechanisms of MBIs for migraine, including mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (MBCT).Expert opinion: While most mindfulness research studies for migraine to date have been pilot trials, which are small and/or lacked rigor, initial evidence suggests there may be improvements in overall headache-related disability and psychological well-being. Many research questions remain to help target the treatment to patients most likely to benefit, including the ideal dosage, duration, delivery method, responder characteristics, and potential mechanisms and biomarkers. A realistic understanding of these factors is important for patients, providers, and the media. Mindfulness will not 'cure' migraine; however, mindfulness may be an important tool as part of a comprehensive treatment approach to help patients 'mindfully' engage in valued life activities.

Abstract
OBJECTIVE To provide a narrative review of clinical development programs for non-oral, non-injectable formulations of dihydroergotamine (DHE) for the treatment of migraine. BACKGROUND Dihydroergotamine was one of the first "synthetic drugs" developed in the 20th century for treating migraine. It is effective and recommended for acute migraine treatment. Since oral DHE is extensively metabolized, it must be given by a non-oral route. Intravenous DHE requires healthcare personnel to administer, subcutaneous/intramuscular injection is challenging to self-administer, and the approved nasal spray formulation exhibits low bioavailability and high variability that limits its efficacy. Currently there are several attempts underway to develop non-oral, non-injected formulations of DHE. METHOD A systematic search of MEDLINE/PubMed and ClinicalTrials.gov databases, then narrative review of identified reports, focusing on those published in the last 10 years. RESULTS Of 1881 references to DHE from a MEDLINE/PubMed search, 164 were from the last 10 years and were the focus of this review. Further cross reference was made to ClinicalTrials.gov for 19 clinical studies, of which some results have not yet been published, or are studies that are currently underway. Three nasal DHE products are in clinical development, reawakening interest in this route of delivery for migraine. Other routes of DHE administration have been, or are being, explored. CONCLUSION There is renewed appreciation for DHE and the need for non-oral, non-injected delivery is now being addressed.
