Responder rates with eptinezumab over 24 weeks in patients with prior preventive migraine treatment failures: post hoc analysis of the DELIVER randomized clinical trial.

BACKGROUND AND PURPOSE: Eptinezumab reduced monthly migraine days more than placebo in the DELIVER study, a clinical trial with patients with difficult-to-treat migraine and prior preventive treatment failures. This post hoc analysis assesses the sustained response to eptinezumab at the population and patient level and evaluates the potential for response in initial non-responders. METHODS: Adults with chronic or episodic migraine and two to four prior preventive treatment failures were randomized to eptinezumab 100 mg, 300 mg or placebo every 12 weeks. Primary outcomes in this post hoc analysis are the proportion of patients with ≥30%, ≥50% or ≥75% reduction in monthly migraine days (i.e., migraine responder rates [MRRs]) during weeks 1-12 and weeks 13-24 and across 4-week intervals. Secondary outcomes are maintenance and shifts in MRRs from weeks 1-12 to weeks 13-24. RESULTS: Between weeks 1-12 and 13-24, ≥30% MRRs increased from 65.9% to 70.4% (100 mg) and from 71.0% to 74.5% (300 mg), versus 36.9% to 43.1% (placebo). The ≥50% and ≥75% MRRs were sustained or increased over the 24-week period. The largest increase in ≥30% MRRs occurred after the second infusion with eptinezumab. The percentage of initial non-responders (<30% MRRs during weeks 1-12) who experienced response (≥30% MRRs during weeks 13-24) to the second dose was 34.7% (100 mg) and 30.4% (300 mg) with eptinezumab versus 21.1% with placebo. CONCLUSION: Across MRR thresholds, most patients who responded to eptinezumab during weeks 1-12 maintained or improved response during weeks 13-24. More than one-third of initial non-responders became responders after their second infusion.

Efficacy and safety of eptinezumab for migraine prevention in patients with prior preventive treatment failures: subgroup analysis of the randomized, placebo-controlled DELIVER study.

BACKGROUND: Migraine is a disabling neurological disease adversely affecting many aspects of life. Most patients are still required to have failed several older oral preventive therapies before being reimbursed for a preventive, migraine-specific anti-calcitonin gene-related peptide treatment. In the 24-week placebo-controlled portion of DELIVER, eptinezumab was shown to reduce migraine frequency and resulted in higher migraine responder rates compared with placebo in patients with two to four previous preventive treatment failures. This subgroup analysis assessed if demographic or clinical characteristics were associated with differences in preventive benefits. METHODS: Migraine frequency reductions and responder rates (i.e., the proportion of patients reaching a ≥50% and ≥75% reduction in monthly migraine days relative to baseline) were determined in the total population and predefined subgroups by sex, age, migraine frequency (chronic migraine, episodic migraine, high-frequency episodic migraine, low-frequency episodic migraine), medication overuse, medication-overuse headache, and previous preventive treatment failures (2, >2). The primary endpoint was change from baseline in monthly migraine days over weeks 1-12. RESULTS: Eptinezumab 100 and 300 mg reduced monthly migraine days more than placebo over weeks 1-12 (-4.8 and -5.3 vs -2.1, respectively; p < 0.0001). In most subgroups, eptinezumab-treated patients demonstrated larger monthly migraine days reductions from baseline over weeks 1-12 than patients receiving placebo, with reductions maintained or increased over weeks 13-24. For ≥50% and ≥75% migraine responder rates, the odds ratios versus placebo all numerically favored eptinezumab. CONCLUSION: Eptinezumab had larger monthly migraine days reductions and higher responder rates than placebo across clinically relevant subgroups showing that, across different demographic populations and clinical characteristics, eptinezumab is effective in patients with migraine and prior preventive treatment failures.Trial Registration: ClinicalTrials.gov (Identifier: NCT04418765).

Eptinezumab improved patient-reported outcomes and quality of life in patients with migraine and prior preventive treatment failures.

BACKGROUND AND PURPOSE: In the phase 3b, randomized, double-blind, placebo-controlled DELIVER clinical trial, eptinezumab reduced migraine frequency and headache in adults with two to four prior preventive treatment failures. Here, the effect of eptinezumab on coinciding patient-reported outcomes is reported. METHODS: Adults were randomized to receive eptinezumab 100, 300 mg or placebo intravenously at weeks 12 and 24. The EQ-5D-5L, measuring overall patient health, and the six-item Headache Impact Test were completed every 4 weeks. The Patient Global Impression of Change was completed at weeks 4, 12 and 24. Patient-identified most bothersome symptom and the Migraine-Specific Quality of Life Questionnaire were administered at weeks 12 and 24. RESULTS: Eptinezumab improved patient-reported outcomes more than placebo, starting at week 4 and at all subsequent time points. By week 12, patients' overall health (EQ-5D-5L visual analog scale score) improved with eptinezumab treatment (difference from placebo in change from baseline: 100 mg, 5.1, 95% confidence interval [CI] 2.2, 8.1, p < 0.001; 300 mg, 7.5, 95% CI 4.5, 10.4, p < 0.0001). At week 12, eptinezumab improved headache-related quality of life (difference from placebo in change from baseline in Headache Impact Test total score: 100 mg, -3.8, 95% CI -5.0, -2.5, p < 0.0001; 300 mg, -5.4, 95% CI -6.7, -4.2, p < 0.0001), including each Migraine-Specific Quality of Life Questionnaire domain (p ≤ 0.0001, all comparisons). Over twice as many patients receiving eptinezumab than placebo reported much or very much improvement on the Patient Global Impression of Change and patient-identified most bothersome symptom. CONCLUSION: Patients with two to four prior preventive treatment failures receiving eptinezumab versus placebo reported greater improvements in well-being, quality of life and most bothersome symptoms compared to placebo.

Long-term effectiveness of eptinezumab in patients with migraine and prior preventive treatment failures: extension of a randomized controlled trial.

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.

Rapid resolution of migraine symptoms after initiating the preventive treatment eptinezumab during a migraine attack: results from the randomized RELIEF trial.

BACKGROUND: Eptinezumab is an anti-calcitonin gene-related peptide (CGRP) monoclonal antibody approved for the preventive treatment of migraine. In the phase 3 RELIEF study, eptinezumab resulted in shorter time to headache pain freedom and time to absence of most bothersome symptom (MBS; including nausea, photophobia, or phonophobia) compared with placebo when administered during a migraine attack. The objective of this exploratory analysis was to examine the earliest time points that eptinezumab separated from placebo (P < .05) on headache- and migraine-associated symptoms when administered during a migraine attack. METHODS: RELIEF, a multicenter, parallel-group, double-blind trial, occurred from November 7, 2019, through July 8, 2020. Adults considered candidates for preventive treatment were randomized to eptinezumab 100 mg (N = 238) or placebo (N = 242) administered intravenously over 30 min within 1-6 h of migraine onset. Outcome measures included headache pain freedom/relief and absence of MBS, patient's choice of photophobia, phonophobia, or nausea, at regular intervals from 0.5 to 48 h after infusion start. Censoring was applied at time of acute rescue medication use. RESULTS: At hour 1, more eptinezumab-treated patients achieved headache pain freedom (9.7%), headache pain relief (38.7%), and absence of MBS (33.2%) versus placebo (4.1%, 26.9%, and 22.1%, respectively; P < .05 all), with separation from placebo (P < .05) through hour 48. Eptinezumab separated from placebo (P < .05) at hour 1 in absence-of-photophobia (29.4% vs 17.0%) and absence-of-phonophobia (41.2% vs 27.2%) and through hour 48. Initial separation from placebo (P < .05) in absence-of-nausea occurred at end-of-infusion (0.5 h; 36.7% vs 25.4%, respectively). CONCLUSION: Preventive treatment with eptinezumab initiated during a migraine attack resulted in more patients achieving headache pain freedom/relief and absence of MBS, with separation from placebo (P < .05) as early as 0.5-1 h following the start of infusion. Rapid resolution of headache- and migraine-associated symptoms by a peripherally acting, intravenously administered antibody suggest a peripheral site of pharmacological action for CGRP blockade.

Effects of eptinezumab on self-reported work productivity in adults with migraine and prior preventive treatment failure in the randomized, double-blind, placebo-controlled DELIVER study.

BACKGROUND: The multinational phase 3b DELIVER trial was designed to evaluate the efficacy and safety of eptinezumab for migraine prevention in patients with prior preventive treatment failures across 17 countries. In the placebo-controlled portion, eptinezumab relative to placebo demonstrated greater reductions in migraine and headache frequency, migraine and headache severity, and acute medication use. The objective of this report is to describe the effects of eptinezumab on self-reported work productivity in the placebo-controlled portion of DELIVER. METHODS: Adults 18-75 years of age with migraine and documented evidence of 2 to 4 prior preventive treatment failures in the past 10 years were randomized to receive eptinezumab 100 mg, 300 mg, or placebo intravenously (IV) every 12 weeks. The Work Productivity and Activity Impairment questionnaire specific to migraine (WPAI:M), which comprises 6 items (4 of which are completed by currently employed patients only), was administered every 4 weeks. Changes from baseline in subscores (absenteeism, presenteeism, work productivity loss, and activity impairment) were calculated based on item responses. A mixed model for repeated measures was used to analyze changes from baseline in WPAI:M subscores. RESULTS: A total of 890 adults (mean age, 43.8 years) were included in the full analysis set (eptinezumab 100 mg, n = 299; eptinezumab 300 mg, n = 293; placebo, n = 298). Mean WPAI:M subscores at baseline indicated a negative impact of migraine attacks on work productivity and ability to complete normal daily activities. Eptinezumab improved WPAI:M subscores more than placebo at all assessment points throughout the study. Mean changes from baseline in self-reported work productivity loss were -19.5, -24.0, and -9.7 at Week 12; and -22.6, -20.2, and -7.2 at Week 24 (all P < 0.001 vs placebo) for eptinezumab 100 mg, eptinezumab 300 mg, and placebo, respectively. Mean changes from baseline in activity impairment were -21.3, -23.8, and -11.2 at Week 12; and -24.7, -22.6, and -10.1 at Week 24 (all P < 0.0001 vs placebo). Similarly, mean improvements in absenteeism and presenteeism were greater in the eptinezumab groups than in the groups receiving placebo at all timepoints (P < 0.05). CONCLUSION: In adults with migraine and prior preventive treatment failure, eptinezumab 100 mg and 300 mg IV every 12 weeks improved absenteeism, presenteeism, work productivity loss, and activity impairment more than placebo.

Efficacy, tolerability, and safety of eptinezumab in patients with a dual diagnosis of chronic migraine and medication-overuse headache: Subgroup analysis of PROMISE-2.

OBJECTIVE: To evaluate the efficacy, tolerability, and safety of eptinezumab 100 and 300 mg compared with placebo in patients with the dual diagnosis of chronic migraine (CM) and medication-overuse headache (MOH). BACKGROUND: Eptinezumab, a humanized monoclonal antibody targeting calcitonin gene-related peptide, may be effective for treating patients with a dual diagnosis of CM and MOH. METHODS: PROMISE-2 (NCT02974153) was a double-blind, randomized, placebo-controlled, phase 3 study that comprised a screening visit, a 28-day pretreatment period, and a 32-week study duration. Patients in this exploratory analysis of a prespecified subgroup had confirmed diagnoses of both CM and MOH at screening. Patients were randomly assigned to receive intravenous eptinezumab 100, 300 mg, or placebo every 12 weeks. Efficacy outcomes included mean changes from baseline in monthly migraine days (MMDs) during weeks 1-12, migraine responder rates at week 12, and percentages of patients below International Classification of Headache Disorders thresholds for CM and MOH over weeks 1-24. RESULTS: There were 431 patients who were diagnosed with CM and MOH as specified in the protocol and received eptinezumab 100 mg (n = 139), 300 mg (n = 147), or placebo (n = 145). During the baseline period, these patients experienced an average of 16.7 migraine days across treatment arms. Over weeks 1-12, eptinezumab-treated patients experienced greater reductions from baseline in MMDs than placebo patients (100 mg, change from baseline = -8.4, difference from placebo [95% confidence interval (CI)] = -3.0 [-4.56, -1.52], p < 0.0001 vs. placebo; 300 mg, change from baseline = -8.6, difference from placebo [95% CI] = -3.2 [-4.66, -1.78], p < 0.0001 vs. placebo; placebo, -5.4). Compared with placebo, more eptinezumab-treated patients were ≥50% migraine responders (100 mg, 84/139 [60.4%]; 300 mg, 91/147 [61.9%]; placebo, 50/145 [34.5%]) or ≥75% responders (100 mg, 38/139 [27.3%]; 300 mg, 44/147 [29.9%]; placebo, 21/145 [14.5%]) over weeks 1-12. Therapeutic benefits with eptinezumab were observed from day 1 after dosing, and improvements were sustained with an additional dose. For the full 24-week treatment period, 71/139 (51.1%), 80/147 (54.4%), and 47/145 (32.4%) of 100, 300 mg, and placebo-treated patients, respectively, were below CM thresholds, and of the patients who provided sufficient acute medication data, 47/93 (50.5%), 53/107 (49.5%), and 26/96 (27.1%), respectively, were below medication-overuse thresholds. CONCLUSIONS: In patients diagnosed with both CM and MOH, eptinezumab treatment resulted in greater reductions in MMDs, higher responder rates, and fewer patients meeting CM and MOH criteria, thus demonstrating the efficacy and clinical utility of eptinezumab in this patient population.

Safety and tolerability of eptinezumab in patients with migraine: a pooled analysis of 5 clinical trials.

BACKGROUND: The 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. METHODS: Data were pooled from four randomized, double-blind, placebo-controlled studies and the first year of one open-label study. RESULTS: The 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. CONCLUSIONS: In adults with migraine, the intravenous administration of eptinezumab every 12 weeks demonstrated a favorable safety and tolerability profile.

The MSOAC approach to developing performance outcomes to measure and monitor multiple sclerosis disability.

BACKGROUND: The Multiple Sclerosis Outcome Assessments Consortium (MSOAC) was formed by the National MS Society to develop improved measures of multiple sclerosis (MS)-related disability. OBJECTIVES: (1) To assess the current literature and available data on functional performance outcome measures (PerfOs) and (2) to determine suitability of using PerfOs to quantify MS disability in MS clinical trials. METHODS: (1) Identify disability dimensions common in MS; (2) conduct a comprehensive literature review of measures for those dimensions; (3) develop an MS Clinical Data Interchange Standards Consortium (CDISC) data standard; (4) create a database of standardized, pooled clinical trial data; (5) analyze the pooled data to assess psychometric properties of candidate measures; and (6) work with regulatory agencies to use the measures as primary or secondary outcomes in MS clinical trials. CONCLUSION: Considerable data exist supporting measures of the functional domains ambulation, manual dexterity, vision, and cognition. A CDISC standard for MS ( http://www.cdisc.org/therapeutic#MS ) was published, allowing pooling of clinical trial data. MSOAC member organizations contributed clinical data from 16 trials, including 14,370 subjects. Data from placebo-arm subjects are available to qualified researchers. This integrated, standardized dataset is being analyzed to support qualification of disability endpoints by regulatory agencies.

COMPARE: Pharmacokinetic profiles of subcutaneous peginterferon beta-1a and subcutaneous interferon beta-1a over 2 weeks in healthy subjects.

AIM: Subcutaneous (s.c.) peginterferon beta-1a injected once every 2 weeks and s.c. interferon beta-1a injected three times per week (Rebif®) have demonstrated efficacy in relapsing-remitting multiple sclerosis, but direct comparisons of pharmacological activity and tolerability between the two products are lacking. COMPARE was an open label, crossover, pharmacokinetic (PK) study evaluating drug exposure and the safety and tolerability of s.c. peginterferon beta-1a and s.c. interferon beta-1a, over 2 weeks in healthy subjects. METHODS: Thirty healthy subjects received one dose of peginterferon beta-1a (125 µg s.c.) or six doses of interferon beta-1a (44 µg s.c.) over 2 weeks, followed by the alternate treatment after a 2 week washout period. Drug concentrations were measured using an enzyme-linked immunosorbent assay (ELISA) and PK parameters including cumulative area under the concentration-time curve (AUC0-336h ) over 2 weeks and maximum observed serum concentrations (Cmax ) were estimated using a non-compartmental analysis. RESULTS: The PK analysis population comprised 26 subjects for each treatment. Drug exposure (AUC0-336h ) was 60% higher with s.c. peginterferon than with s.c. interferon beta-1a (117.4 ng ml(-1) h, 95% confidence interval 95.6, 144.3 vs. 73.1 ng ml(-1) h, 95% confidence interval 61.2, 87.3, respectively; P < 0.0001). Injection-site reactions (ISRs) were the most common adverse events (AEs) observed with both treatments. Numerically lower frequencies and incidence rates of ISRs, headache, myalgia and chills were observed with s.c. peginterferon beta-1a. CONCLUSIONS: One dose of s.c. peginterferon delivered significantly greater drug exposure than s.c. interferon beta-1a three times a week over 2 weeks, and a lower frequency of AEs.

Relationship between sustained disability progression and functional system scores in relapsing-remitting multiple sclerosis: analysis of placebo data from four randomized clinical trials.

BACKGROUND: The Expanded Disability Status Scale (EDSS), based on different functional system scores (FSS), remains the most frequently used disability assessment in relapsing-remitting multiple sclerosis (RRMS). In this analysis, we evaluated the relationship between sustained disability progression, measured by EDSS, and simultaneous changes in individual FSS domains. METHODS: A post hoc analysis was performed on data from placebo-treated RRMS patients from four large, randomized, multicenter, phase 3 clinical trials. Sustained disability progression was defined as a ≥1.0-point EDSS score increase over a ≥3- or ≥6-month period. Simultaneous sustained disability progression and worsening of individual FSS domains was analyzed. RESULTS: The majority of patients experienced sustained disability progression and simultaneous worsening of ≥1 FSS domain, with ≥1-point worsening in the pyramidal domain being most frequently associated with sustained disability progression (in 31-51% of patients), followed by ≥1-point worsening in the cerebellar (35-41% of patients) and sensory (31-45% of patients) domains. CONCLUSION: The key FSS components correlating with sustained disability progression, measured by EDSS, appear to be pyramidal, cerebellar, and sensory. In this analysis, the simultaneous worsening of consistent FSS domains confirms the validity and reliability of the use of sustained EDSS progression as a measure of disability progression.

Eptinezumab Demonstrated Efficacy Regardless of Prior Preventive Migraine Treatment Failure Type: Post Hoc Analyses of the DELIVER Study.

INTRODUCTION: In the DELIVER study, eptinezumab reduced monthly migraine days (MMDs) more than placebo in patients with 2-4 prior preventive migraine treatment failures. This post hoc analysis evaluated the efficacy of eptinezumab across the 24-week placebo-controlled period of the DELIVER study in subgroups defined by prior treatment failure type. METHODS: DELIVER (NCT04418765) randomized adults with migraine to eptinezumab 100 mg, 300 mg, or placebo, administered intravenously every 12 weeks. Changes from baseline in MMDs and percentages of patients with ≥ 50% reduction from baseline in MMDs (≥ 50% migraine responder rates [MRRs]) were summarized in subgroups of patients defined by prior treatment failure type. Subgroups were not mutually exclusive and included patients for whom topiramate, beta blockers (metoprolol, propranolol), amitriptyline, and/or flunarizine had failed. RESULTS: Across Weeks 1-12 in all subgroups, patients treated with eptinezumab experienced greater reductions from baseline in MMDs than those receiving placebo (reductions ranged from 4.5-5.5 vs 1.6-2.4, respectively), with larger reductions over Weeks 13-24. Similarly, ≥ 50% MRRs were consistently higher with eptinezumab than placebo and increased following a second infusion. CONCLUSION: In all subgroups, regardless of prior preventive treatment failure type, eptinezumab demonstrated greater reductions in MMDs and higher MRRs compared with placebo.

Safety and efficacy of eptinezumab for migraine prevention in patients with two-to-four previous preventive treatment failures (DELIVER): a multi-arm, randomised, double-blind, placebo-controlled, phase 3b trial.

BACKGROUND: The monoclonal antibody eptinezumab, which targets calcitonin gene-related peptide, has shown migraine preventive effects starting the day following infusion and acceptable safety and tolerability in phase 3 trials, but benefits in the subpopulations of patients with previous preventive treatment failures were not examined. We aimed to investigate the safety and efficacy of eptinezumab for migraine prevention in adults with migraine and two-to-four previous preventive treatment failures. METHODS: DELIVER was a multicentre, multi-arm, phase 3b trial comprising a 24-week double-blind, placebo-controlled period and a 48-week dose-blinded extension. We recruited adults with episodic or chronic migraine with at least 4 monthly migraine days (as per International Headache Society guidelines) and documented evidence of two-to-four previous preventive treatment failures within the past 10 years, from 96 study locations across Europe (n=93) and the USA (n=3). Patients were randomly assigned (1:1:1) via a centralised randomisation system, stratified by baseline monthly headache days and country, to eptinezumab 100 mg, eptinezumab 300 mg, or placebo. The primary efficacy endpoint was the change from baseline in mean monthly migraine days (captured using a daily electronic diary) in weeks 1-12, assessed in the full analysis set. All participants and study personnel were masked to study drug assignments. The dose-blinded extension period is ongoing. The trial is registered with ClinicalTrials.gov, NCT04418765, and EudraCT, 2019-004497-25. FINDINGS: Between June 1, 2020, and Oct 7, 2021, 891 individuals were randomly assigned and received at least one dose of study drug (safety population; eptinezumab 100 mg n=299 [34%], eptinezumab 300 mg n=294 [33%], placebo n=298 [33%]). 865 patients completed the placebo-controlled period. The change from baseline to weeks 1-12 in mean monthly migraine days was -4·8 (SE 0·37) with eptinezumab 100 mg, -5·3 (0·37) with eptinezumab 300 mg, and -2·1 (0·38) with placebo. The difference from placebo in change in mean monthly migraine days from baseline was significant with eptinezumab 100 mg (-2·7 [95% CI -3·4 to -2·0]; p<0·0001) and eptinezumab 300 mg (-3·2 [-3·9 to -2·5]; p<0·0001). Treatment-emergent adverse events occurred in 127 (42%) of 299 patients in the eptinezumab 100 mg group, in 120 (41%) of 294 in the eptinezumab 300 mg group, and in 119 (40%) of 298 in the placebo group. The most common treatment-emergent adverse event was COVID-19 (20 [7%] of 299 patients in the eptinezumab 100 mg group, 17 [6%] of 294 in the eptinezumab 300 mg group, and 16 [5%] of 298 in the placebo group). Serious adverse events were uncommon (five [2%] of 299 in the eptinezumab 100 mg group, seven [2%] of 294 in the eptinezumab 300 mg group, four [1%] of 298 in the placebo group) and included anaphylactic reaction (eptinezumab 300 mg n=2) and COVID-19 (eptinezumab 100 mg n=1 and eptinezumab 300 mg n=1). INTERPRETATION: In adults with migraine and two-to-four previous preventive treatment failures, eptinezumab provided significant migraine preventive effects compared with placebo, with acceptable safety and tolerability, indicating that eptinezumab might be an effective treatment option for this patient population. The dose-blinded extension period will provide additional long-term safety data in patients with migraine and previous preventive treatment failures. FUNDING: H Lundbeck.

Active immunotherapy and alternative therapeutic modalities for Alzheimer's disease.

As knowledge of Alzheimer's disease (AD) progression improves, the field has recognized the need to diversify the pipeline, broaden strategies and approaches to therapies, as well as delivery mechanisms. A better understanding of the earliest biological processes of AD/dementia would help inform drug target selection. Currently there are a number of programs exploring these alternate avenues. This meeting will allow experts in the field (academia, industry, government) to provide perspectives and experiences that can help elucidate what the pipeline looks like today and what avenues hold promise in developing new therapies across the stages of AD. The focus here is on Active Immunotherapies and Alternative Therapeutic Modalities. This topic includes active vaccines, antisense oligomers, and cell-based therapy among others, and highlights new clinical developments that utilize these modalities.

Patients transitioning from non-pegylated to pegylated interferon beta-1a have a low risk of new flu-like symptoms: ALLOW phase 3b trial results.

BACKGROUND: Flu-like symptoms are common adverse events associated with interferon beta relapsing multiple sclerosis therapies. OBJECTIVES: To evaluate the incidence and severity of flu-like symptoms after transitioning from non-pegylated interferons to peginterferon beta-1a and assess flu-like symptom mitigation using naproxen. METHODS: ALLOW was a phase 3b open-label study in relapsing multiple sclerosis patients. Patients had received non-pegylated interferon for 4 or more months immediately before beginning a 4-week screening period. At baseline, patients switched to peginterferon beta-1a and were randomly assigned (1:1) to continue their current flu-like symptoms management regimen or start twice-daily naproxen 500 mg for 8 weeks. Patients then switched to their preferred regimen and were followed for 48 weeks in total. RESULTS: Of 201 patients, 89.6% did not experience new/worsening flu-like symptoms during their first 8 weeks on peginterferon beta-1a. Flu-like symptom severity remained low in current-regimen and naproxen patients, with no significant between-group differences. Median flu-like symptom duration per injection was 3.2 hours longer with peginterferon beta-1a versus prior interferon, but the 4-week cumulative duration was reduced 49-78%. No new safety signals were identified. CONCLUSION: Most patients who switched from non-pegylated interferon to peginterferon beta-1a did not experience new/worsening flu-like symptoms. Flu-like symptom duration per injection increased, but the cumulative duration significantly decreased. These data may inform flu-like symptom management guidance.

Multiple sclerosis patients treated with intramuscular IFN-ß-1a autoinjector in a real-world setting: prospective evaluation of treatment persistence, adherence, quality of life and satisfaction.

OBJECTIVES: The 12-month observational PERSIST study (NCT01405872) evaluated adherence associated with the intramuscular IFNß-1a (i.m. IFN-ß-1a) autoinjector pen in multiple sclerosis (MS) patients. METHODS: MS patients initiating i.m. IFN-ß-1a autoinjector treatment were prospectively assessed for physician-reported persistence (percentage of patients remaining on therapy) and patient-reported outcomes, including adherence (percentage of unmissed injections), compliance (percentage of patients missing no injections), tolerability (injection-site reactions [ISRs] and pain) and satisfaction. RESULTS: The intent-to-treat population included 232 patients; of the 188 physician-reported 12-month completers, 182 patients remained on treatment (96.8% persistence). Monthly compliance rates were 87.5 - 96.2%. Mean monthly pain scores were 1.5 - 1.8 (scale: 0 = 'no pain'; 10 = 'extremely painful'). At 12 months, 73.5% of respondents reported no ISRs, 94.9% were satisfied/very satisfied with the autoinjector and 88.2% found using the device easy/very easy. Injection fear, injection anxiety and need for injection assistance by caregivers decreased from the initial visit to 12 months. No new safety signals were observed. CONCLUSIONS: The autoinjector pen is associated with high levels of persistence, compliance, adherence, and satisfaction, little-to-no pain and low need for caregiver assistance. Although these data are limited by reliance on patient questionnaires and the absence of a direct comparator group, this treatment may reduce barriers to injection therapy, while supporting long-term MS management.

Neuron loss after coronary artery bypass detected by SPECT estimation of benzodiazepine receptors.

BACKGROUND: Cerebral dysfunction is common after cardiac surgery and probably related to embolic phenomena, but the etiological mechanisms have not been elucidated. The aim of this study was to assess whether a possible neuron loss could be detected by single photon emission computer tomography (SPECT) estimation of benzodiazepine receptor density. In addition, we correlated the findings with neuropsychological test results. METHODS: We included 15 elderly patients undergoing coronary artery bypass surgery. Neuropsychological testing was performed before surgery and postoperatively at discharge from hospital and after 3 months using a neuropsychological test battery. SPECT was performed before surgery and after 3 months using the iomazenil bolus/infusion technique, and the benzodiazepine receptor density was calculated for the frontal, parietal, temporal, and occipital cortex. RESULTS: Cognitive dysfunction was found in 46.7% at discharge from hospital and in 6.7% after 3 months. A significant decrease in the estimated density of neurons was found in the frontal cortex, but no significant correlation was found between cognitive dysfunction and SPECT findings. CONCLUSIONS: Neuron loss was detectable in the frontal cortex, but the decrease did not correlate with neuropsychological test results.

Cerebral blood flow and cognitive dysfunction after coronary surgery.

BACKGROUND: Postoperative cognitive dysfunction after cardiac surgery has been attributed both to embolic events and periods with reduced cerebral perfusion. We investigated whether cognitive dysfunction after coronary surgery is associated with changes in regional cerebral blood flow (CBF) using single photon emission computed tomography. METHODS: Before surgery and at discharge, 15 coronary surgery patients were studied. Global and regional CBF were measured using a brain-dedicated single photon emission computed tomography scanner, and neuropsychological testing with seven subtests was performed. Postoperative cognitive dysfunction was defined as a Z score above 2. Normative single photon emission computed tomography data were available from 26 healthy age-matched controls. RESULTS: Preoperative global CBF was significantly lower in patients compared with controls (53.7 versus 46.1 mL/100 g/min, p = 0.006). After surgery, global CBF significantly decreased in the patient group (46.1 versus 38.6 mL/100 g/min, p = 0.0001). No significant differences were detected in regional CBF. Cognitive dysfunction was identified in 4 of the 15 patients (26.7%, 95% CI 7.8% to 55.1%). No correlation was found between the neuropsychological Z score and global or regional CBF. CONCLUSIONS: The significant decrease in CBF after coronary surgery was uniformly distributed and was not correlated to postoperative cognitive dysfunction.
