Multidimensional assessment of the effects of erenumab in chronic migraine patients with previous unsuccessful preventive treatments: a comprehensive real-world experience.

ABSTRACT: BACKGROUND:erenumab was safe and effective in clinical trials for the prevention of migraine. However, real-life data are still lacking. Here we report the clinical experience from an Italian real-world setting using erenumab in patients with chronic migraine experiencing previous unsuccessful preventive treatments. METHODS:Seventy patients with chronic migraine and failure to ?4 migraine preventive medication classes initially received monthly erenumab 70?mg?s.c. Patients without a clinically meaningful improvement, considered as a?>?30% reduction in headache days per month, after ?3?months of therapy switched to monthly erenumab 140?mg. At the first administration and after 3 and 6?months, patients underwent extensive interviews to assess clinical parameters of disease severity and migraine-related disability and impact, and validated questionnaires to explore depression/anxiety, sleep, and quality of life (QoL). Finally, the Pain Catastrophizing Scale, Allodynia Symptom Checklist-12 and MIGraine attacks-Subjective COGnitive impairments scale (MIG-SCOG) were administered. RESULTS:70% of patients were "responders" after the third administration of erenumab 70?mg, whereas 30% switched to erenumab 140?mg; 29% (6 pts) responded after the sixth administration. The headache-day frequency was reduced from 21.1?±?0.7 to 11.4?±?0.9?days after the third administration (p?

Project description:BackgroundErenumab is a fully human monoclonal antibody and a highly potent, first-in-class calcitonin gene-related peptide receptor inhibitor approved for migraine prevention in adults. Randomised, placebo-controlled trials show that erenumab treatment results in clinically meaningful responses, including significant reductions in monthly migraine days. Real-world evidence of the effectiveness of erenumab in patients with migraine is accruing, but gaps remain, and findings may vary according to region. We evaluated the usage patterns and effectiveness of erenumab in real-world settings in patients with migraine in the United Arab Emirates (UAE).MethodsThis retrospective, observational real-world study enrolled patients ≥ 18 years with migraine who were prescribed erenumab in the UAE. Data were collected at baseline and Months 1, 3 and 6. The primary study objective was to characterise usage patterns of erenumab in patients with chronic migraine (CM) or episodic migraine (EM) in real-world settings in the UAE.ResultsOf the 166 patients, 124 (74.7%) were females. The mean (standard deviation) age at migraine onset was 29 (7.93) years. Seventy-one patients (42.8%) had CM and 95 (57.2%) had EM. In the overall population, the mean monthly headache/migraine days (MHD) at baseline was 15.7 (8.45) and mean change from baseline was - 8.2 (8.83) at Month 1, - 11.0 (9.15) at Month 3 and - 11.3 (8.90) at Month 6. The mean change from baseline in monthly acute migraine-specific medication days (MSMD) was - 9.0 (8.07) at Month 1, - 9.7 (8.73) at Month 3 and - 10.7 (8.95) at Month 6. At all time points, most patients achieved at least 50% reduction in MHD (80%-91%) and MSMD (84%-94%). Similar reductions in MHD and MSMD and clinical benefit in CM or EM were seen with erenumab monotherapy or erenumab add-on therapy, with or without dose escalation and for treatment naïve or ≥ 1 previous preventive treatment failures, with additional clinical benefit in the erenumab add-on therapy and dose escalation to 140 mg subgroups.ConclusionIn this real-world study on erenumab use in the UAE, patients prescribed erenumab achieved clinically meaningful reductions in MHD and MSMD at all assessed time points. Erenumab was well tolerated with no new safety events.

Project description:ObjectivesSystematic review of preventive pharmacologic treatments for community-dwelling adults with episodic migraine.Data sourcesElectronic databases through May 20, 2012.Eligibility criteriaEnglish-language randomized controlled trials (RCTs) of preventive drugs compared to placebo or active treatments examining rates of ?50 % reduction in monthly migraine frequency or improvement in quality of life.Study appraisal and synthesis methodsWe assessed risk of bias and strength of evidence and conducted random effects meta-analyses of absolute risk differences and Bayesian network meta-analysis.ResultsOf 5,244 retrieved references, 215 publications of RCTs provided mostly low-strength evidence because of the risk of bias and imprecision. RCTs examined 59 drugs from 14 drug classes. All approved drugs, including topiramate (9 RCTs), divalproex (3 RCTs), timolol (3 RCTs), and propranolol (4 RCTs); off-label beta blockers metoprolol (4 RCTs), atenolol (1 RCT), nadolol (1 RCT), and acebutolol (1 RCT); angiotensin-converting enzyme inhibitors captopril (1 RCT) and lisinopril (1 RCT); and angiotensin II receptor blocker candesartan (1 RCT), outperformed placebo in reducing monthly migraine frequency by ?50 % in 200-400 patients per 1,000 treated. Adverse effects leading to treatment discontinuation (68 RCTs) were greater with topiramate, off-label antiepileptics, and antidepressants than with placebo. Limited direct evidence as well as frequentist and exploratory network Bayesian meta-analysis showed no statistically significant differences in benefits between approved drugs. Off-label angiotensin-inhibiting drugs and beta-blockers were most effective and tolerable for episodic migraine prevention.LimitationsWe did not quantify reporting bias or contact principal investigators regarding unpublished trials.ConclusionsApproved drugs prevented episodic migraine frequency by ?50 % with no statistically significant difference between them. Exploratory network meta-analysis suggested that off-label angiotensin-inhibiting drugs and beta-blockers had favorable benefit-to-harm ratios. Evidence is lacking for long-term effects of drug treatments (i.e., trials of more than 3 months duration), especially for quality of life.

Project description:ObjectivesTo assess real-world effectiveness, safety, and usage of erenumab in Canadian patients with episodic and chronic migraine with prior ineffective prophylactic treatments.BackgroundIn randomized controlled trials, erenumab demonstrated efficacy for migraine prevention in patients with ≤4 prior ineffective prophylactic migraine therapies. The "Migraine prevention with AimoviG: Informative Canadian real-world study" (MAGIC) assessed real-world effectiveness of erenumab in Canadian patients with migraine.MethodsMAGIC was a prospective open-label, observational study conducted in Canadian patients with chronic migraine (CM) and episodic migraine (EM) with two to six categories of prior ineffective prophylactic therapies. Participants were administered 70 mg or 140 mg erenumab monthly based on physician's assessment. Migraine attacks were self-assessed using an electronic diary and patient-reported outcome questionnaires. The primary outcome was the proportion of subjects achieving ≥50% reduction in monthly migraine days (MMD) after the 3-month treatment period.ResultsAmong the 95 participants who mostly experienced two (54.7%) or three (32.6%) prior categories of ineffective prophylactic therapies and who initiated erenumab, treatment was generally safe and well tolerated; 89/95 (93.7%) participants initiated treatment with 140 mg erenumab. At week 12, 32/95 (33.7%) participants including 17/64 (26.6%) CM and 15/32 (48.4%) EM achieved ≥50% reduction in MMD while 30/86 (34.9%) participants including 19/55 (34.5%) CM and 11/31 (35.5%) EM achieved ≥50% reduction in MMD at week 24. Through patient-reported outcome questionnaires, 62/95 (65.3%) and 45/86 (52.3%) participants reported improvement of their condition at weeks 12 and 24, respectively. Physicians observed improvement in the condition of 78/95 (82.1%) and 67/86 (77.9%) participants at weeks 12 and 24, respectively.ConclusionOne-third of patients with EM and CM achieved ≥50% MMD reduction after 3 months of erenumab treatment. This study provides real-world evidence of erenumab effectiveness, safety, and usage for migraine prevention in adult Canadian patients with multiple prior ineffective prophylactic treatments.

Project description:ObjectiveThe objective of this study was to ascertain to what extent adults with migraine value an early onset of efficacy for preventive migraine treatments.BackgroundIn placebo-controlled clinical trials, treatment with eptinezumab resulted in a lower proportion of adults with migraine on the first day following infusion (day 1; 14% point-reduction for chronic migraine [CM] in PROMISE-2 and 8% point-reduction for episodic migraine [EM] in PROMISE-1).MethodsAdults with migraine completed an online preference-elicitation thresholding exercise to ascertain to what extent they value not having a migraine on day 1 postdosing relative to a clinically relevant reduction in number of migraine days during the first month postdosing (≥2 migraine-free days for CM and ≥1 migraine-free days for EM).ResultsOne hundred and one participants (mean age, 50.6 ± 12.4 years; 81 [80%] women) were included. In participants with CM, 29 of 50 (58%) considered the eptinezumab-generated reduction in the likelihood of migraine on day 1 postdosing to be at least as important as a clinically relevant reduction in number of migraine days the first month postdosing, whereas 37 of 50 (74%) considered a clinically relevant reduction of migraine days the first month postdosing to have a value equivalent to the eptinezumab-generated reduction in the likelihood of migraine on day 1 postdosing. In participants with EM, 18 of 35 (51%) considered the eptinezumab-generated reduction in the likelihood of migraine on day 1 postdosing to be at least as important as a clinically relevant reduction in migraine days the first month postdosing, whereas 24 of 35 (69%) considered a clinically relevant reduction of migraine days the first month postdosing to have a value equivalent to the eptinezumab-generated reduction in the likelihood of migraine on day 1 postdosing.ConclusionMost participants considered the reduction in the likelihood of migraine offered by eptinezumab on day 1 postdosing to be at least as important as a clinically relevant reduction in migraine days the first month postdosing.

Project description:IntroductionNumerous medications are used for the preventive treatment of chronic migraine (CM), including oral treatments, onabotulinumtoxinA (onabotA; BOTOX), and calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAbs). Despite substantial clinical trial evidence, less is published about the real-world experience of these treatments based on data routinely collected from a variety of sources. This systematic review assessed real-world evidence on the effectiveness and safety of preventive treatments for CM in adults.MethodsA systematic search of MEDLINE, Embase, and the Cochrane library with back-referencing and supplementary searches retrieved data published between January 2010 and February 2020. Publications were screened, extracted, and quality assessed. Data were narratively synthesized. Search criteria included preventive medications for CM. Evidence was available for topiramate, onabotulinumtoxinA, CGRP mAbs (erenumab, galcanezumab, and fremanezumab). OnabotulinumtoxinA was most commonly assessed (55 studies), followed by erenumab (six studies), multiple CGRP mAbs (one study), and topiramate (one study). Long-term data (> 1 year) were available for onabotulinumtoxinA only, with erenumab reported up 6 months, topiramate up to 3 months, and multiple CGRP mAbs up to 12 months.ResultsSubstantial data demonstrated that onabotulinumtoxinA reduces the number/frequency of headaches, concomitant acute medication use, and impact of headaches on well-being and daily activity. More limited evidence showed benefits for the same parameters with erenumab. Single studies suggested topiramate and multiple CGRP mAbs decrease the number/frequency of headaches and impact of headaches. To date, onabotulinumtoxinA is the only preventive treatment for CM that has long-term safety data in real-world settings reporting treatment-related adverse events of up to 3 years.ConclusionWhile substantial real-world evidence supports the long-term effectiveness and safety of onabotulinumtoxinA, real-world data on other preventive treatments of CM are currently limited to short term effectiveness due to their more recent approvals.

Project description:ObjectiveTo examine the cardiovascular, cerebrovascular, and peripheral vascular safety of erenumab across migraine prevention studies.MethodsVascular 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.ResultsIn 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.ConclusionSelective 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.Clinicaltrialsgov identifiersNCT02066415, NCT02456740, NCT01952574, NCT02483585, NCT02174861, and NCT01723514.Classification of evidenceThis analysis provides Class II evidence that for patients with migraine, erenumab does not increase the risk of vascular AEs.
