Blood pressure monitoring in elderly migraineurs starting an anti-CGRP monoclonal antibody: a real-world prospective study. Neurol Sci 2024:10.1007/s10072-024-07567-9. [PMID: 38795273 DOI: 10.1007/s10072-024-07567-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Accepted: 04/27/2024] [Indexed: 05/27/2024]
Abstract
BACKGROUND While monoclonal antibodies (mAbs) targeting the CGRP pathway have revolutionized migraine management due to their improved tolerance and adherence, concerns remain about their potential impact on blood pressure (BP), especially in older patients, due to CGRP-mediated vasodilation blockade. Given the growing use of these therapies in older populations, assessing their cardiovascular (CV) safety is of paramount importance. METHODS This multicentric observational prospective study focused on migraine sufferers aged ≥ 60 who began erenumab, galcanezumab, or fremanezumab for prevention. Baseline, three-month, and twelve-month BP measurements were collected. Changes in antihypertensive medication and "Newly or Worsened Hypertensive" patients (NWHP) were assessed. RESULTS Among 155 patients receiving anti-CGRP mAbs (40 Erenumab, 47 Galcanezumab, 68 Fremanezumab), 42.5% had hypertension history and 39% were on antihypertensive treatment. No significant systolic or diastolic BP changes occurred at any time point compared to baseline (all p > 0.05), with no differences between the three groups. After one year, 20/155 (12.9%) patients were considered NWHP; 11/20 had prior hypertension, and 5/11 adjusted antihypertensive therapy. Among 9/20 newly hypertensive patients, 5/9 had a single measurement above the normal threshold with no requirement for new pharmacological therapy. A higher baseline BP value was associated with increased BP (p = 0.002). CONCLUSIONS The study concludes that treatment with anti-CGRP mAbs over one year does not significantly affect BP in patients aged ≥ 60, nor does it increase the incidence of hypertension compared to general population trends. Nonetheless, continuous monitoring and further long-term studies are necessary to fullya scertain the cardiovascular safety of these medications in the elderly.

Abstract
BACKGROUND AND OBJECTIVES The LIBERTY study assessed the efficacy and safety of erenumab in participants with episodic migraine (EM) and 2-4 prior preventive treatment failures. The results have been presented after 3 years of erenumab exposure in its open-label extension phase (OLEP). METHODS Participants completing the 12-week double-blind treatment phase (DBTP) of the LIBERTY study could enter the OLEP and receive 140 mg of erenumab once monthly for 3 years. The main outcomes included the proportion of participants achieving ≥50% reduction in monthly migraine days (MMDs), the mean MMD change from baseline, and tolerability and safety. RESULTS Overall, 240/246 (97.6%) participants entered the OLEP and 168/240 (70.0%) completed the study (85/118 continuing erenumab [n = 1 lost during follow-up]; 83/122 switching from placebo [n = 2 lost during follow-up]). In the overall population, 79/151 participants (52.3%) with valid data points achieved ≥50% reduction in MMDs at week 168 (i.e., responders). In the continuous erenumab group, 35/117 participants (29.9%) were ≥50% responders at week 12 of the DBTP and 26/35 (74.3%) remained ≥50% responders in at least half of OLEP visits. Of the 82/117 participants (70.1%) not achieving responder status at week 12 in the continuous erenumab group, 17/82 (20.7%) converted to ≥50% responders in at least half of OLEP visits. Of 103/120 participants (85.8%) not achieving responder status at week 12 in the placebo-erenumab group, 42/103 (40.8%) converted to ≥50% responders in at least half of OLEP visits after switching to erenumab. Overall, the mean (SD) MMD change from baseline showed sustained improvement over 3 years (-4.4 [3.9] days at week 168). The most common treatment-emergent AEs (per 100 person-years) were nasopharyngitis (28.8), influenza (7.5), and back pain (5.8). Overall, 9.6% (3.9 per 100 person-years) and 6.7% (2.7 per 100 person-years) of participants reported events of treatment-emergent hypertension and constipation, respectively. The safety and tolerability profile remained consistent with earlier studies. DISCUSSION Erenumab (140 mg) showed sustained efficacy over 3 years in participants with EM and 2-4 prior preventive treatment failures. No new safety signals were observed. TRIAL REGISTRATION INFORMATION ClinicalTrials.gov Identifier: NCT03096834.

Abstract
Migraine is a highly prevalent neurological disorder. Among the risk factors identified, psychiatric comorbidities, such as depression, seem to play an important role in its onset and clinical course. Patients with migraine are 2.5 times more likely to develop a depressive disorder; this risk becomes even higher in patients suffering from chronic migraine or migraine with aura. This relationship is bidirectional, since depression also predicts an earlier/worse onset of migraine, increasing the risk of migraine chronicity and, consequently, requiring a higher healthcare expenditure compared to migraine alone. All these data suggest that migraine and depression may share overlapping biological mechanisms. Herein, this review explores this topic in further detail: firstly, by introducing the common epidemiological and risk factors for this comorbidity; secondly, by focusing on providing the cumulative evidence of common biological aspects, with a particular emphasis on the serotoninergic system, neuropeptides such as calcitonin-gene-related peptide (CGRP), pituitary adenylate cyclase-activating polypeptide (PACAP), substance P, neuropeptide Y and orexins, sexual hormones, and the immune system; lastly, by remarking on the future challenges required to elucidate the etiopathological mechanisms of migraine and depression and providing updated information regarding new key targets for the pharmacological treatment of these clinical entities.

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

Abstract
The new Calcitonin Gene-Related Peptide (CGRP)-targeted therapies have proven high efficacy and tolerability in episodic and chronic migraine. Eptinezumab is a humanized monoclonal antibody that selectively binds CGRP with high affinity. Eptinezumab was approved by the Food and Drug Administration on February 21st, 2020, for the preventive treatment of migraine in adults. It is administered intravenously over 30 minutes with a standard dose of 100 mg and has a T-max of 30 minutes-1 hour and a half-life of 27 days. These pharmacological properties allow for a very rapid onset of effect and a quarterly administration. It is the first time that a preventive treatment for migraine can be offered as an intravenous administration. As the range of therapeutic possibilities in migraine is expanding, the treatment process must include common decision-making, where physicians should explain in detail to patients the different characteristics of treatment options beyond efficacy and side effects. Patients can now express a preference on a range of opportunities: pharmacological versus non-pharmacological approaches, route of administration, frequency of administration, efficacy, rapidity, side effects, costs, the possibility of titration or dosing, and durability of effectiveness at suspension. Also, patient preferences can be influenced by age, country, migraine severity, and earlier experience with CGRP-targeted therapies. Besides, adherence may be influenced by several factors, including route and the schedule of administration. This narrative review describes a new perspective from the patient's point of view. Clinicians should ally with patients to select treatments that meet each patient's needs and thus apply a tailored approach, addressing not only headaches. In this way, physicians would care for the patients globally and stand out their preferences on different aspects of treatment. Besides, healthcare professionals shall be aware that patients' beliefs about therapies are subject to change with increasing experience with new therapeutic approaches.

Abstract
BACKGROUND Eptinezumab demonstrated efficacy in adults with migraine and prior preventive treatment failures in the placebo-controlled phase of the DELIVER clinical trial; its long-term effectiveness in this population has not yet been reported. The objective of this study was to evaluate the long-term effectiveness of eptinezumab in a migraine patient population during the 48-week extension phase of DELIVER. METHODS DELIVER was conducted June 1, 2020 to September 15, 2022. 865 adults with migraine, with documented evidence of 2-4 prior preventive migraine treatment failures and with completion of the 24-week placebo-controlled period of DELIVER received eptinezumab (100 or 300 mg) during the dose-blinded extension, either continuing their randomized dose or, if originally receiving placebo, were randomized 1:1 to an eptinezumab dose (100 or 300 mg). A mixed model for repeated measures was used to evaluate changes from baseline in the number of monthly migraine days (MMDs). RESULTS Of 865 patients entering the extension (eptinezumab 100 mg, n = 433; 300 mg, n = 432), 782 (90.4%) completed and 11 (1.3%) discontinued due to an adverse event. Eptinezumab was associated with early and sustained reductions in migraine frequency. Mean MMDs at baseline were approximately 14 days across groups. Mean (standard error) change from baseline in MMDs over the final dosing interval (weeks 61-72) was -6.4 (0.50) with placebo/eptinezumab 100 mg, -7.3 (0.49) with placebo/eptinezumab 300 mg, -7.1 (0.39) with eptinezumab 100 mg, and -7.0 (0.39) with eptinezumab 300 mg. During weeks 61-72, 63-70% of patients demonstrated ≥ 50% reduction in MMDs, and 36-45% demonstrated ≥ 75% reduction. Headache severity and acute medication use reductions, and patient-reported improvements in most bothersome symptom, disease status, quality of life, and work productivity, were observed. Adverse events were generally mild, transient, and similar in frequency/type to previous eptinezumab trials. CONCLUSIONS The long-term effectiveness and safety/tolerability of eptinezumab in patients with migraine and 2-4 prior preventive treatment failures was demonstrated by high completion rates and migraine-preventive benefits sustained for up to 18 months, implying that eptinezumab is a viable long-term treatment option for patients still seeking successful migraine treatments.

Abstract
BACKGROUND Migraine is a brain disorder with recurrent headache attacks and altered sensory processing. Introvision is a self-regulation method based on mindfulness-like perception techniques, developed at the University of Hamburg. Here, we examined the effect of Introvision in migraine prevention. METHODS Migraineurs with at least five headache days per month were block-randomized to the experimental group (EG) or waiting list group (WL), the latter starting Introvision training six weeks after the EG. Participants learned Introvision in six weekly on-site group sessions with video-conference support followed by three individual video-conference sessions. Headache diaries and questionnaires were obtained before Introvision training and three months after the last individual Introvision session. RESULTS Fifty-one patients completed the study. The primary outcome, headache days of the EG after Introvision training compared to those of the WL before the training, showed no significant effect (10.6 ± 7.7, n = 22; vs. 10.9 ± 6.3, n = 29, p = 0.63; Mann-Whitney-U-Test). The secondary outcome, comparing pooled EG and WL data before and after Introvision training, revealed a significant reduction of headache days (from 11.7 ± 6.5 to 9.8 ± 7.0; p = 0.003; Wilcoxon-paired-Test) as well as of acute medication intake and Headache-Impact-Test 6 (HIT-6) scores and increased self-efficacy as quantified by increased FKMS-scores (FKMS: german short form of the Headache Management Self-Efficacy Scale (HMSE)). CONCLUSION Although the study did not reach its primary endpoint, several secondary outcome parameters in the pooled (non-controlled) pre-post analysis showed an improvement with a decrease in monthly headache days by 1.9 days/ month. A larger randomized controlled trial has to corroborate these preliminary findings. TRIAL REGISTRATION NCT03507400, Registration date 09.03.2018.

Abstract
BACKGROUND Calcitonin gene-related peptide-targeted drugs have proven safe and effective for migraine prevention in large randomized-controlled, double-blind trials with an average duration of six months. Open-label studies may provide additional information on the long-term safety and efficacy of these substances. METHODS We searched PubMed for open-label trials with calcitonin gene-related peptide(-receptor) monoclonal antibodies and calcitonin gene-related peptide-receptor antagonists. We summarized and critically analyzed the literature in a narrative way. RESULTS Overall, 13 open-label trials were included in this review (n = 4 for erenumab, n = 4 for galcanezumab, n = 3 for fremanezumab, n = 1 for eptinezumab, n = 1 for atogepant). Open-label trial duration ranged between 12 and 264 weeks. No safety concerns emerged, and the adverse events profile was similar to the double-blind study phase. Discontinuation rates were generally low with >75% of patients remaining in the trials after one year. Efficacy data showed a sustained reduction of migraine frequency throughout the trials, along with a lasting improvement in quality of life. CONCLUSIONS The open-label study program for calcitonin gene-related peptide-targeted migraine preventives confirms the favorable safety and efficacy profile of these drugs over time. Treatment adherence appears higher than with previous unspecific migraine preventives. Real-world data and post-marketing surveillance studies may corroborate and complement open-label results.

Abstract
Purpose To demonstrate a need for improved health insurance coverage for anti-obesity medications (AOMs) by comparing clinical and economic benefits of obesity treatments to covered medications for selected therapeutic areas. Methods Using a grey literature search, we identified and prioritized therapeutic areas and treatment analogues for comparison to obesity. A targeted literature review identified clinical and economic outcomes research across the therapeutic area analogues. Associated comorbidities, clinical evidence, indirect costs (ie, absenteeism and productivity loss), and direct medical costs were evaluated to determine the relative value of treating obesity. Results Four therapeutic areas/treatment analogues were selected for comparison to obesity: smoking cessation (varenicline), daytime sleepiness (modafinil), migraines (erenumab), and fibromyalgia (pregabalin). Obesity was associated with 17 comorbidities, more than migraine (9), smoking (8), daytime sleepiness (5), and fibromyalgia (2). Economic burden was greatest for obesity, followed by smoking, with yearly indirect and direct medical costs totaling $676 and $345 billion, respectively. AOMs resulted in cost savings of $2586 in direct medical costs per patient per year (PPPY), greater than that for varenicline at $930 PPPY, modafinil at $1045 PPPY, and erenumab at $468 PPPY; pregabalin utilization increased costs by $924 PPPY. AOMs were covered by 10-16% of United States health insurance plans, compared to 45-59% for the four comparators. Conclusion Compared to four therapeutic analogues, obesity represented the highest economic burden and was associated with more comorbidities. AOMs provide greater cost savings compared to selected analogues. However, AOMs have limited formulary coverage. Improved coverage of AOMs may increase access to these treatments and may help address the clinical and economic burden associated with obesity and its comorbidities.

Medium-term real-world data for erenumab in 177 treatment resistant or difficult to treat chronic migraine patients: persistence and patient reported outcome measures after 17-30 months. J Headache Pain 2023; 24:5. [PMID: 36647006 PMCID: PMC9841480 DOI: 10.1186/s10194-022-01536-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2022] [Accepted: 12/17/2022] [Indexed: 01/18/2023] Open
Abstract
BACKGROUND Many migraine patients do not respond adequately to conventional preventive treatments and are therefore described as treatment/medically resistant or difficult to treat cases. Calcitonin gene-related peptide monoclonal antibodies are a relatively novel molecular treatment for episodic and chronic migraine that have been shown to be effective in short duration clinical trials in approximately 40-50% of all chronic migraine patients. Patient Related Outcome Measures (PROM) or Quality of Life (QoL) questionnaires are used to help measure response to treatment in migraine. Although some open label extension studies have become available for erenumab, there is a lack of real-world data pertaining to quality of life in the medium to long-term for chronic and treatment resistant migraine patients. METHODS A total of 177 treatment resistant CM patients were started on erenumab (70 mg or 140 mg subcutaneous injection every 4 weeks) in our three specialist Headache Clinics. Of these, 174 had their first injection between December 2018 and October 2019. All patients were evaluated with the following PROM: the Headache Impact Test- 6, Migraine Associated Disability Assessment test and Migraine-Specific QoL Questionnaire, before starting treatment with erenumab and at intervals of 3-12 months after starting treatment. The decision to continue treatment was based on subjective clinical improvement of at least 30% (as reported by the patient), supported with diaries and QoL questionnaires. We present here the QoL measurements for this group of 177 patients. Prior preventive migraine treatments included conventional oral prophylactic medications (such as topiramate, candesartan, propranolol, or amitriptyline), at least two cycles of PREEMPT protocol onabotulinumtoxin A or (in a small number of cases) neuromodulation with single pulse Transcranial Magnetic Stimulation. RESULTS Of the 177 patients who started treatment with erenumab, 68/177 (38.4%) stopped during the first year, either due to lack of efficacy (no significant benefit or only minimal improvement) and/or possible side effects. 109/177 (61.6%) patients reported clinically significant improvement after 6-12 months and wished to stay on treatment. Twelve of these 109 patients subsequently stopped treatment in the period between 1 year and up to June 2021 (mainly due to a worsening of their migraine). Therefore, a total of 97/177 patients (54.8%) remained on treatment as of June 2021 (duration of treatment 17-30 months, median of 25 months). CONCLUSION Approximately 55% of treatment resistant or difficult to treat CM patients who trialled erenumab in our clinics reported a subjective benefit and were still on treatment after 17-30 months.

Does MIDAS reduction at 3 months predict the outcome of erenumab treatment? A real-world, open-label trial. J Headache Pain 2022; 23:123. [PMID: 36115947 PMCID: PMC9482180 DOI: 10.1186/s10194-022-01480-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Accepted: 08/10/2022] [Indexed: 11/10/2022] Open
Abstract
Abstract
Background
In Italy, monoclonal antibodies targeting the CGRP pathway are subsidized for the preventive treatment of high frequency and chronic migraine (CM) in patients with a MIgraine Disability ASsessment (MIDAS) score ≥ 11. Eligibility to treatment continuation requires a ≥ 50% MIDAS score reduction at three months (T3). In this study, we evaluate whether a ≥ 50% MIDAS score reduction at T3 is a reliable predictor of response to one-year erenumab treatment.
Methods
In this prospective, open-label, real-world study, 77 CM patients were treated with erenumab 70–140 mg s.c. every 28 days for one year (T13). We collected the following variables: monthly migraine days (MMDs), monthly headache days (MHDs), days of acute medication intake, MIDAS, HIT-6, anxiety, depression, quality of life and allodynia. Response to erenumab was evaluated as: i) average reduction in MMDs during the 1-year treatment period; and ii) percentage of patients with ≥ 50% reduction in MMDs during the last 4 weeks after the 13th injection (RespondersT13).
Results
Erenumab induced a sustained reduction in MMDs, MHDs and intake of acute medications across the 12-month treatment period, with 64.9% of patients qualifying as RespondersT13. At T3, 55.8% of patients reported a ≥ 50% reduction in MIDAS score (MIDASRes) and 55.4% of patients reported a ≥ 50% reduction in MMDs (MMDRes). MIDASRes and MMDRes patients showed a more pronounced reduction in MMDs during the 1-year treatment as compared to NON-MIDASRes (MIDASRes: T0: 23.5 ± 4.9 vs. T13: 7.7 ± 6.2; NON- MIDASRes: T0: 21.6 ± 5.4 vs. T13: 11.3 ± 8.8, p = 0.045) and NON-MMDRes (MMDRes: T0: 23.0 ± 4.5 vs. T13: 6.6 ± 4.8; NON-MMDRes: T0: 22.3 ± 6.0 vs. T13: 12.7 ± 9.2, p < 0.001) groups. The percentage of RespondersT13 did not differ between MIDASRes (74.4%) and NON-MIDASRes (52.9%) patients (p = 0.058), while the percentage of RespondersT13 was higher in the MMDRes group (83.3%) when compared to NON-MMDRes (42.9%) (p = 0.001). MMDRes predicted the long-term outcome according to a multivariate analysis (Exp(B) = 7.128; p = 0.001), while MIDASRes did not. Treatment discontinuation based on MIDASRes would have early excluded 36.0% of RespondersT13. Discontinuation based on “either MIDASResor MMDRes” would have excluded a lower percentage (16%) of RespondersT13.
Conclusion
MIDASRes only partly reflects the 12-month outcome of erenumab treatment in CM, as it excludes more than one third of responders. A criterion based on the alternative consideration of ≥ 50% reduction in MIDAS score or MMDs in the first three months of treatment represents a more precise and inclusive option.
Trial registration
The trial was retrospectively registered at www.clinicaltrials.gov (NCT05442008).

Abstract
Background Controlled and real-world evidence have demonstrated the efficacy of calcitonin gene related peptide (CGRP) monoclonal antibodies (MABs) in migraine. However, data on the over-one-year sustained effectiveness of CGRP MABs in resistant chronic migraine (CM) is sparse. Methods This is a two-year real-world prospective analysis of an ongoing single centre audit conducted in patients with resistant CM. Patients received monthly erenumab for six months before assessing its effectiveness. Responders were considered those who achieved at least 30% reduction in monthly migraine days (MMD) by month 6, compared to baseline. Secondary outcomes were also analysed, including changes of the Headache Impact Test version 6 (HIT-6). Results One hundred sixty-four patients [135 (82.3%) females; mean age 46 SD 14) years] were included in the audit and 160 patients analysed. Patients had failed a mean of 8.4 preventive treatments at baseline. At month 6, 76 patients (48%) were 30% responders to erenumab, 50 patients (31%) were 50% responders and 25 (15%) were 75% responders. The mean reduction in MMD at month 6 was 7.5 days compared to baseline (P < 0.001). At month 12 and month 18, 61 patients (38%) and 52 patients (33%) remained 30% responders respectively. At month 24, 36 patients (23%) remained 30% responders, 25 patients (16%) and 13 patients (8%) were respectively 50% and 75% responders. Compared to 95% of patients at baseline, at months 6, 12 and 24, 46%, 29% and 16% of responders respectively had severe disability. At least one adverse event at month 6, 12, 18 and 24 was reported by 49%, 19%, 11% and 3% of patients. By month 6, 13% of patients discontinued the treatment because of side effects, often constipation. Conclusions Long-term sustained effectiveness of erenumab was reported only by a minority of resistant CM patients. Although more research in resistant migraine is needed, Erenumab can provide long-term meaningful reduction in migraine load and migraine-related disability in some patients.

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

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

Central effects of galcanezumab in migraine: a pilot study on Steady State Visual Evoked Potentials and occipital hemodynamic response in migraine patients. J Headache Pain 2022; 23:52. [PMID: 35484504 PMCID: PMC9052688 DOI: 10.1186/s10194-022-01421-z] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Accepted: 04/11/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The discovery of the prominent action of Calcitonin Gene Related Peptide -CGRP- on trigeminal afferents and meningeal vessels, opened a new era in migraine treatment. However, how the block of nociceptive afferents could act on central mechanisms of migraine is still not clear. In this pilot study we aimed to test the effect of 3 months Galcanezumab (CGA) therapy on occipital visual reactivity in migraine patients, using the Steady State Visual Evoked Potentials-SSVEPs and Functional Near Infrared Spectroscopy -fNIRS. METHOD Thirteen migraine patients underwent clinical and neurophysiological examination in basal condition (T0), 1 h after GCA injection (T1) and after 3 months of GCA treatment (T2). Ten healthy volunteers were also evaluated. RESULTS At T2, there was a reduction of headache frequency and disability. At T2, the EEG power significantly diminished as compared to T0 and T1 at occipital sites, and the topographical analysis confirmed a restoration of SSVEPs within normal values. The Oxyhemoglobin levels in occipital cortex, which were basically increased during visual stimulation in migraine patients, reverted to normal values at T2. CONCLUSIONS The present pilot study indicates that Galcanezumab could act on cortical targets located beyond the pain network, restoring the abnormal occipital reactivity. This effect could indicate the possible disease modifying properties of CGRP related monoclonal antibodies.

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

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

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

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.

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
The diagnosis of chronic migraine (CM) is made when there are 15 or more days of headache per month in a patient with migraine. Approximately 2.5% of patients with episodic migraine develop chronic migraine, which is more difficult to treat and often leads to drug-induced headache (LIH). Such patients are rarely included in clinical trials.
Aim. To analyze in clinical practice the effectiveness of the CGRP monoclonal antibody erenumab after 6 months of therapy in patients with CM with and without LIHD, and to evaluate possible predictors of the effectiveness of prophylactic therapy.
Materials and methods. The study included 47 patients with CM taking erenumab at a dose of 70 mg monthly for at least 3 months. Patients completed a headache diary throughout the study. The 12-item Allodynia Symptom Checklist (ACS-12) was used to assess the presence of allodynia. After 6 months of therapy, the efficacy and safety of treatment, the presence of LAH and possible predictors of efficacy were evaluated.
Results. After 6 months of therapy, 22 (78.6%) patients no longer met the criteria for LIHD. The factors that positively influenced the outcome of therapy were the absence of allodynia (p0.05), the presence of photo- and phonophobia, and the one-sidedness of pain (p0.05). The age and number of days with headache in patients with HM before treatment did not have a statistically significant effect on the effect of therapy. The presence of LIHD did not statistically significantly affect the outcome of therapy.
Conclusion. CGRP monoclonal antibodies are reasonable in patients with LIHD. The presence of LIHD does not affect the efficacy of erenumab prophylactic therapy, the presence of allodynia may be a predictor of failure, and the unilaterality of pain and irritability to light and sound indicate likely efficacy. Real-world studies with a large cohort of patients and longer durations of therapy are required to confirm these results.

Abstract
INTRODUCTION Results from the open-label extension of the phase 3b CONQUER trial are presented to evaluate the effectiveness and safety of galcanezumab, a monoclonal antibody targeting calcitonin gene-related peptide, for up to 6 months in patients with multiple prior migraine preventive treatment failures. METHODS Patients were 18-75 years old with episodic or chronic migraine and 2-4 standard-of-care migraine preventive medication category failures. After 3 months of randomized treatment with galcanezumab (120 mg/month with 240 mg loading dose; n = 232) or placebo (n = 230), patients entered a 3-month open-label extension (120 mg/month galcanezumab with a blinded 240 mg loading dose for previous-placebo patients). Primary efficacy measure was mean change from double-blind baseline in monthly migraine headache days. RESULTS A total of 432/449 patients (96%) who entered open-label treatment completed the study. Mean change in monthly migraine headache days in the total population, which was - 1.3 for placebo and - 4.4 for galcanezumab patients at the end of double-blind treatment (p < 0.001), was - 5.2 and - 5.6, respectively, at the end of open-label treatment with galcanezumab. Among patients with episodic migraine, mean change in monthly migraine headache days had been - 0.6 for placebo and - 2.8 for galcanezumab after double-blind treatment (p < 0.001) and was - 4.5 and - 3.8, respectively, after open-label treatment. Among patients with chronic migraine, mean change in monthly migraine headache days had been - 2.5 for placebo and - 6.6 for galcanezumab after double-blind treatment (p < 0.001) and was - 6.5 and - 8.2, respectively, after open-label treatment. Adverse events were similar to those observed during double-blind placebo treatment. Review of data in elderly patients (65-75 years of age) indicated that galcanezumab was well tolerated in this age group, with no safety issues identified. CONCLUSIONS Galcanezumab was effective and safe during open-label treatment in patients who had experienced failures of previous migraine preventives.
