Abstract 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.

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 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

Abstract 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

Abstract 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.

Abstract 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.
