ABSTRACT: Objective
To evaluate the efficacy and safety of eptinezumab, a humanized anti-calcitonin gene-related peptide monoclonal antibody, in the preventive treatment of chronic migraine (CM).Methods
The Prevention of Migraine via Intravenous ALD403 Safety and Efficacy-2 (PROMISE-2) study was a phase 3, multicenter, randomized, double-blind, placebo-controlled, parallel-group study. Adults with CM were randomly assigned to receive IV eptinezumab 100 mg, eptinezumab 300 mg, or placebo administered on day 0 and week 12. The primary endpoint was change from baseline in mean monthly migraine days (MMDs) over weeks 1 to 12.Results
Among treated participants (n = 1,072), baseline mean number of MMDs was ≈16.1 across groups. Treatment with eptinezumab 100 and 300 mg was associated with significant reductions in MMDs across weeks 1 to 12 compared with placebo (placebo -5.6, 100 mg -7.7, p < 0.0001 vs placebo; 300 mg -8.2, p < 0.0001 vs placebo). Treatment-emergent adverse events (TEAEs) were reported by 43.5% (100 mg), 52.0% (300 mg), and 46.7% (placebo) of patients. Nasopharyngitis was the only TEAE reported for >2% of eptinezumab-treated patients at an incidence of >2% over placebo; it occurred in the 300 mg eptinezumab arm (eptinezumab 9.4%, placebo 6.0%).Conclusion
In patients with CM, eptinezumab 100 and 300 mg was associated with a significant reduction in MMDs from the day after IV administration through week 12, was well tolerated, and demonstrated an acceptable safety profile.Classification of evidence
This study provides Class I evidence that for patients with CM, a single dose of eptinezumab reduces MMDs over 12 weeks of treatment.Clinicaltrialsgov identifier

Project description:BackgroundPROMISE-2 was a phase 3, randomized, double-blind, placebo-controlled study that evaluated the efficacy and safety of repeat intravenous (IV) doses of the calcitonin gene-related peptide-targeted monoclonal antibody eptinezumab (ALD403) for migraine prevention in adults with chronic migraine. This report describes the results of PROMISE-2 through 24 weeks of treatment.MethodsPatients received up to two 30-min IV administrations of eptinezumab 100 mg, 300 mg, or placebo separated by 12 weeks. Patients recorded migraine and headache endpoints in a daily eDiary. Additional assessments, including patient-reported outcomes, were performed at regularly scheduled clinic visits throughout the 32-week study period (screening, day 0, and weeks 2, 4, 8, 12, 16, 20, 24, and 32).ResultsA total of 1072 adults received treatment: eptinezumab 100 mg, n = 356; eptinezumab 300 mg, n = 350; placebo, n = 366. The reduction in mean monthly migraine days observed during the first dosing interval (100 mg, - 7.7 days; 300 mg, - 8.2 days; placebo, - 5.6 days) was further decreased after an additional dose (100 mg, - 8.2 days; 300 mg, - 8.8 days; placebo, - 6.2 days), with both doses of eptinezumab demonstrating consistently greater reductions from baseline compared to placebo. The ≥50% and ≥ 75% migraine responder rates (MRRs) increased after a second dose, with more eptinezumab-treated patients experiencing migraine response than placebo patients (≥50% MRRs weeks 13-24: 100 mg, 61.0%; 300 mg, 64.0%; placebo, 44.0%; and ≥ 75% MRRs weeks 13-24: 100 mg, 39.3%; 300 mg, 43.1%; placebo, 23.8%). The percentages of patients who improved on patient-reported outcomes, including the Headache Impact Test and Patient Global Impression of Change, increased following the second dose administration at week 12, and were greater with eptinezumab than with placebo at all time points. No new safety concerns were identified with the second dose regarding the incidence, nature, and severity of treatment-emergent adverse events.ConclusionEptinezumab 100 mg or 300 mg administered IV at day 0 and repeated at week 12 provided sustained migraine preventive benefit over a full 24 weeks and demonstrated an acceptable safety profile in patients with chronic migraine.Trial registrationClinicalTrials.gov (Identifier: NCT02974153 ).

Project description:BackgroundFor some people with migraine, despite taking greater amounts of acute headache medication (AHM), they develop an increase in monthly headache days. This cycle of increasing headache days, and in turn AHM use, can lead to a secondary headache disorder called medication-overuse headache (MOH). Preventive medications can prevent migraine from occurring and reduce reliance on AHMs, thereby preventing the cycle of MOH. This study was performed to evaluate the efficacy and safety of eptinezumab to prevent migraine/headache in a mainly Asian patient population with a dual diagnosis of chronic migraine and MOH.MethodsSUNLIGHT was a phase 3, multicenter, double-blind, parallel-group, placebo-controlled trial. Patients aged 18-75 years with ≥ 8 migraine days/month and a diagnosis of MOH were randomly allocated (1:1) to one of two treatment groups: eptinezumab 100 mg or placebo. Monthly migraine days (MMDs) were captured using a daily electronic diary; the change from baseline in the number of MMDs over Weeks 1-12 was the primary efficacy endpoint.ResultsPatients were randomized to eptinezumab 100 mg (n = 93) or placebo (n = 100). Over Weeks 1-12, eptinezumab reduced mean MMDs more than placebo (difference between treatments was -1.2; p = 0.1484). Differences between treatment groups with p-values below 0.05 favoring eptinezumab were observed in 3 out of the 6 key secondary endpoints.ConclusionAll endpoints numerically favored eptinezumab treatment when compared to placebo; however, this study did not meet its primary endpoint and is therefore negative. No new safety signals were identified in this study, like previous reports that confirmed the safety and tolerability of eptinezumab treatment.Trial registrationClinicalTrials.gov identifier: NCT04772742 (26/02/2021).

Project description:ObjectiveTo examine changes in the occurrence, severity, and symptoms of headache episodes in patients with chronic migraine following eptinezumab treatment.MethodsPROMISE-2 was a double-blind, placebo-controlled, parallel-group trial that randomized adults with chronic migraine to eptinezumab 100 mg, 300 mg, or placebo IV every 12 weeks for up to 24 weeks (2 infusions). Headache episodes (migraine and non-migraine) and their characteristics were reported in daily electronic diaries during the 28-day baseline and throughout the 24-week treatment period.ResultsA total of 1072 patients were included in this post hoc analysis. Mean monthly headache days decreased by 8.9 (100 mg) and 9.7 (300 mg) compared to a 7.3 decrease in placebo over the first 4-week interval post initial dose and reductions were maintained throughout the 24-week treatment period. Mean monthly headache episodes also decreased by 8.4 (100 mg) and 9.0 (300 mg) compared to a decrease of 7.1 with placebo. The proportion of headache episodes that were migraine attacks decreased by 11.2% (100 mg), 12.4% (300 mg), and 3.9% (placebo), and among remaining headaches decreases in severe pain, nausea, phonophobia, photophobia, and physical activity limitations were numerically greater than placebo.ConclusionsPatients with chronic migraine treated with eptinezumab decreased the monthly severity and frequency of headache days and episodes more than placebo. Beyond decreased headache frequency, patients treated with eptinezumab reported a reduction in the percent of remaining headache episodes that were migraine attacks, as well as a decrease in burdensome symptoms of headache episodes, indicating additional decreased headache severity after eptinezumab treatment.Trial registration: ClinicalTrials.gov Identifier: NCT02974153; registered November 23, 2016.

Project description:OBJECTIVE:To evaluate the efficacy and safety of eptinezumab, a humanized anti-calcitonin gene-related peptide monoclonal antibody, in the preventive treatment of episodic migraine. METHODS:The PRevention Of Migraine via Intravenous ALD403 Safety and Efficacy-1 (PROMISE-1) study was a phase 3, multicenter, randomized, double-blind, placebo-controlled, parallel-group study. Adults with episodic migraine were randomized to eptinezumab 30?mg, 100?mg, 300?mg, or placebo for up to four intravenous (IV) doses administered every 12 weeks. The primary endpoint was change from baseline in monthly migraine days (MMDs) over weeks 1-12. RESULTS:A total of 888 patients received treatment across 84 study sites. Mean MMDs at baseline was ?8.6 across treatment groups. Eptinezumab 100?mg and 300?mg met the primary endpoint, significantly reducing MMDs across weeks 1-12 compared with placebo (30?mg, -4.0; 100?mg, -3.9, p?=?0.0182; 300?mg, -4.3; placebo, -3.2, p?=?0.0001). Treatment-emergent adverse events were reported by 58.4% (30?mg), 63.2% (100?mg), 57.6% (300?mg), and 59.5% (placebo) of patients. Treatment-emergent adverse events reported by ?2% of eptinezumab-treated patients at an incidence greater than placebo included: upper respiratory tract infection (30?mg, 11.4%; 100?mg, 9.9%; 300?mg, 10.3%; placebo, 7.2%), and fatigue (30?mg, 2.3%; 100?mg, 3.6%; 300?mg, 3.6%; placebo, <1%). CONCLUSION:Eptinezumab (100?mg or 300?mg) significantly reduced migraine frequency, was well tolerated, and had an acceptable safety profile when used for the preventive treatment of migraine in adults with episodic migraine.

Project description:BackgroundEptinezumab, an anti-calcitonin gene-related peptide monoclonal antibody recently approved in the United States for preventive treatment of migraine in adults, was found to be well tolerated in double-blind, placebo-controlled studies in patients with episodic and chronic migraine. The objective of the PREVAIL study was to evaluate the long-term safety, immunogenicity, and impact on patient-reported outcomes of repeat doses of eptinezumab in patients with chronic migraine.MethodsPREVAIL was an open-label, phase 3 trial comprising a 48-week treatment phase followed by a second 48-week treatment phase. Adults with chronic migraine received eptinezumab 300 mg by 30-min intravenous administration every 12 weeks for up to 8 doses. Patients were followed for 20 weeks after the final infusion (end-of-study visit at week 104).ResultsOverall, 128 adults (mean age, 41.5 years) with chronic migraine were included. During the 2 years, the most frequently reported treatment-emergent adverse events were nasopharyngitis (14.1%), upper respiratory tract infection (7.8%), sinusitis (7.8%), influenza (6.3%), bronchitis (5.5%), and migraine (5.5%). The rate of study-drug discontinuation due to adverse events was 6.3%, which included 3 patients with infusion-related hypersensitivity. The incidence of anti-eptinezumab antibodies peaked at week 24 and declined despite continued dosing, to nondetectable levels at week 104. Improvements in patient-reported outcomes were observed at first assessment (week 4) and generally sustained through week 104.ConclusionIn adults with chronic migraine, eptinezumab 300 mg demonstrated a favorable safety profile, limited long-term immunogenicity, early and sustained reductions in migraine-related burden, and improvements in health-related quality of life over 2 years.Trial registrationClinicalTrials.gov (Identifier: NCT02985398 ).

Project description:ObjectiveTo determine the onset of preventive efficacy with eptinezumab in patients with migraine.BackgroundEptinezumab is a monoclonal antibody inhibiting calcitonin gene-related peptide approved as an intravenously administered treatment for the prevention of migraine.MethodsPatients who received eptinezumab 100 mg, eptinezumab 300 mg, or placebo in PROMISE7-1 (episodic migraine; 100 mg, n = 221; 300 mg, n = 222; placebo, n = 222) or PROMISE7-2 (chronic migraine; 100 mg, n = 356; 300 mg, n = 350; placebo, n = 366) were included. Testing of the percentage of patients with a migraine on day 1 after dosing was prespecified and alpha-controlled. In further exploration of this prespecified endpoint, a post hoc closed testing procedure, which controlled the false-positive (type 1) error rate, provided a statistically rigorous evaluation of migraine prevention onset. The procedure involved up to 84 tests of significance, all of which were performed in sequence until the first nonsignificant result.ResultsFor both studies, all tests for significance for eptinezumab 100 and 300 mg, from days 1-84 through day 1 alone, achieved nominal significance (P < .05), indicating that eptinezumab was fully effective beginning on day 1. Over each interval, the treatment effect was comparable to the effect over weeks 1-12. Mean changes from baseline in monthly migraine days for the primary endpoint period ranged from -3.9 to -4.9, -4.1 to -4.9, and -2.2 to -3.2 for eptinezumab 100, 300 mg, and placebo, respectively, in PROMISE7-1 and from -7.2 to -8.0, -7.9 to -8.2, and -4.3 to -5.6, respectively, in PROMISE7-2. The difference from placebo (95% confidence interval) in day 1 treatment effect was -2.2 (-4.1, -0.3) and -2.5 (-4.4, -0.6) days/month for eptinezumab 100 and 300 mg, respectively, in PROMISE7-1, and was -3.8 (-5.6, -2.0) and -4.0 (-5.8, -2.1) days/month for 100 and 300 mg, respectively, in PROMISE7-2.ConclusionsThe migraine preventive effect of eptinezumab is rapid and sustained in patients with episodic or chronic migraine, with onset of optimal preventive efficacy observed on the day following the initial dose.

Project description:BackgroundA clinical ability to describe the response trajectory of patients receiving preventive migraine treatment could expedite and improve therapeutic management decisions. This post hoc analysis of the PROMISE-2 study evaluated the consistency and predictive power of Month 1 treatment response on later response in patients with chronic migraine.MethodsPROMISE-2 was a double-blind, placebo-controlled trial that randomized adults with chronic migraine to eptinezumab 100 mg, 300 mg, or placebo administered IV every 12 weeks for up to 24 weeks (2 infusions over 6 study months). Migraine responder rates (MRRs) were calculated from monthly migraine days over 4-week intervals compared with baseline. Patients were grouped by MRR during Month 1 (< 25%, 25-< 50%, 50-< 75%, and ≥ 75%), with the number of subsequent study months (Months 2-6) with ≥50% and ≥ 75% MRR calculated in each subgroup. A similar analysis was conducted using Patient Global Impression of Change (PGIC) rating to define Month 1 subgroups (very much improved, much improved, minimally improved, and no change/worse) and rates of very much improved or much improved PGIC during Months 2-6.ResultsIn the eptinezumab 100 mg, 300 mg, and placebo groups, respectively, 194/356 (54.5%), 212/350 (60.6%), and 132/366 (36.1%) patients were ≥ 50% migraine responders during Month 1. More eptinezumab-treated patients were ≥ 75% migraine responders (100 mg, 110/356 [30.9%]; 300 mg, 129/350 [36.9%]; placebo, 57/366 [15.6%]) and more placebo-treated patients were < 25% migraine responders (eptinezumab 100 mg, 103/356 [28.9%]; 300 mg, 80/350 [22.9%]; placebo, 153/366 [41.8%]). Among patients who achieved ≥75% migraine response in Month 1, more than one-third attained ≥75% migraine response for all 5 subsequent study months and more than two-thirds achieved ≥75% migraine response for ≥3 months. More than two-thirds of those in the very much improved (PGIC) subgroup at Month 1 were much or very much improved for all 5 subsequent months.ConclusionsIn this post hoc analysis of data from PROMISE-2, more eptinezumab-treated than placebo-treated patients were early (Month 1) responders, and most early responders went on to achieve a high level of response for at least half of the 24-week treatment period. Potential for later response in early non-responders was also observed.Trial registrationClinicalTrials.gov identifier: NCT02974153 ; registered November 23, 2016.

Project description:BackgroundThe humanized anti-CGRP monoclonal antibody eptinezumab has been evaluated in five large-scale clinical trials conducted in patients with migraine. This integrated analysis was conducted to evaluate the comprehensive safety and tolerability of eptinezumab in patients with migraine across these studies.MethodsData were pooled from four randomized, double-blind, placebo-controlled studies and the first year of one open-label study.ResultsThe pooled population comprised 2867 adults with migraine: eptinezumab, n = 2076 (4797 infusions); placebo, n = 791 (1675 infusions). A total of 1137/2076 (54.8%) patients who received eptinezumab and 414/791 (52.3%) patients who received placebo experienced ≥1 treatment-emergent adverse event (TEAE); rates were similar across eptinezumab dose groups (10-1000 mg). For most patients with TEAEs, the events were mild or moderate in severity and considered unrelated to study drug by the investigators. Thirty infusion-site AEs occurred in 27/2076 (1.3%) patients who received eptinezumab and 7 in 7/791 (0.9%) patients who received placebo. Infusion-site AEs led to infusion interruption in 19/2076 (0.9%) and 5/791 (0.6%) patients in the eptinezumab and placebo groups, respectively. Nasopharyngitis occurred in ≥2% of patients in the eptinezumab 300-mg group and with an incidence of at least 2 percentage points greater than in the placebo group; however, in most patients (eptinezumab, 139/140; placebo 40/41), its occurrence was considered not related to study treatment. Adverse events coded to hypersensitivity occurred for 23/2076 (1.1%) patients treated with eptinezumab and no patients in the placebo group. If additional TEAE terms that could indicate hypersensitivity are considered (e.g., urticaria, flushing/hot flush, rash, and pruritus), hypersensitivity reactions in the two pivotal placebo-controlled phase 3 studies occurred in ≥2% of patients in the eptinezumab 100-mg and 300-mg groups, and the incidence was at least 2 percentage points greater in either of these groups than in the placebo group. Most hypersensitivity reactions were not serious and resolved with standard medical treatment or observation without treatment, usually within 1 day.ConclusionsIn adults with migraine, the intravenous administration of eptinezumab every 12 weeks demonstrated a favorable safety and tolerability profile.Trial registrationClinicalTrials.gov (Identifiers: NCT01772524 , NCT02275117 , NCT02559895 , NCT02974153 , NCT02985398 ).

Project description:BackgroundEptinezumab is an anti-calcitonin gene-related peptide humanized monoclonal antibody approved for the preventive treatment of migraine in adults. The PREVAIL study demonstrated a favorable safety profile with sustained reductions in overall migraine-related burden in patients with chronic migraine (CM). This post hoc analysis aimed to examine item-level changes in the Migraine Disability Assessment (MIDAS) questionnaire over 2 years in participants with CM on eptinezumab treatment.MethodsPREVAIL was an open-label, phase 3 trial that included 96 weeks of treatment where 128 adults received intravenous eptinezumab administered over 30 min every 12 weeks (wks) for up to 8 doses of 300 mg. MIDAS was administered at baseline, Wk12, and every 12wks thereafter. Two supplementary MIDAS items not included in the total score calculation assessed number of headache days in the past 3 months (MIDAS headache) and average headache pain severity (from 0 [none] to 10 [worst]). MIDAS total scores were summed from 5 items, each quantifying the number of days in the past 3 months with migraine-related disability. Items 1, 3, and 5 assessed absenteeism, namely how many days the patient missed work/school (Q1), household work (Q3), or family/social/leisure activities (Q5). Items 2 and 4 were measures of presenteeism, namely how many days the patient had reduced productivity in work/school (Q2) or household work (Q4).ResultsMean MIDAS headache days decreased from 47.4 (baseline) to 17.1 (Wk12) and 16.3 (Wk104). The average headache pain severity score (0‒10) decreased from a mean of 7.3 (baseline) to 5.5 (Wk12) to 4.5 (Wk104). Mean MIDAS scores measuring absenteeism (Q1, 3, 5) changed from 9.7 days at baseline to 3.2 days (Wk12) and to 3.9 days (Wk104). Mean MIDAS scores measuring presenteeism (Q2, 4) at Wk12 decreased from 14.2 days at baseline to 5.2 days (Wk12, 104). Patients categorized with very severe MIDAS disability had a mean total MIDAS score of 84.8, with an average reduction of 56.7 days (Wk12), which was maintained at 32 days at Wk104.ConclusionsLong-term treatment with eptinezumab in patients with CM suggested sustained reductions in MIDAS-quantified disability, consistent with the sustained reductions in headache frequency and pain severity.Trial registrationClinicalTrials.gov identifier: NCT02985398 .

Project description:ObjectiveTo evaluate the efficacy and safety of eptinezumab versus placebo in patients ≥50 years old with episodic (EM) or chronic migraine (CM).Materials and methodsThis post hoc analysis included data from two phase 3, parallel-group, randomized, double-blind, placebo-controlled studies in adults with EM (PROMISE-1) or CM (PROMISE-2). Patients ≥50 years at baseline treated with eptinezumab 100 mg, 300 mg, or placebo were pooled from both studies to evaluate efficacy and safety.ResultsA total of 385/1960 (19.6%) EM and CM patients who were ≥50 years old at baseline (range, 50-71 and 50-65 years, respectively) received eptinezumab 100 mg (n = 132), 300 mg (n = 127), or placebo (n = 126) over Weeks 1-12. Reductions in mean monthly migraine days (MMDs) in ≥50-year-old EM patients were -3.8 (100 mg) and -4.4 (300 mg) with eptinezumab versus -2.6 with placebo. In ≥50-year-old CM patients, mean changes in MMDs were -7.7 (100 mg) and -8.6 (300 mg) with eptinezumab versus -6.0 with placebo. Changes in MMDs were comparable to total study results. A ≥50% MMD reduction over Weeks 1-12 was achieved by 57.9% of eptinezumab-treated versus 35.7% of patients who received placebo, and a ≥75% reduction by 30.5% versus 13.5%, respectively. The incidence of treatment-emergent adverse events (TEAEs) in EM and CM patients ≥50 years old was similar across treatment groups, with ≥96% of TEAEs mild or moderate in severity.ConclusionsTreatment with eptinezumab was efficacious, tolerable, and safe in patients ≥50 years with EM or CM, congruent with results from the overall study population.
