Background and Objectives
Cenobamate (CNB) is a new antiseizure medication (ASM) to treat drug-resistant, focal-onset seizures. Data on its use in early therapy lines are not yet available, and clinicians frequently consider CNB to be a later ASM drug choice. We investigated the efficacy and safety of CNB as an early adjunctive treatment in drug-resistant, focal-onset seizures.
Methods
The study population were patients with drug-resistant, focal-onset seizures who were initiated with CNB after they did not respond to two or three lifetime ASMs, including all prior and concomitant ASMs. These patients were matched (1:2) by sex, age, and seizure frequency to controls who were initiated with any ASM other than CNB. All participants participated in the Mainz Epilepsy Registry. We evaluated the retention rate after 12 months of CNB and after each new adjunctive ASM in the control group. In addition, seizure freedom and the response rate (reduction of seizure frequency by ≥ 50% from baseline) after 12 months were estimated.
Results
We included 231 patients aged 44.4 ± 15.8 years. Of these, 33.3% (n = 77) were on CNB, 19.0% (n = 44) on valproate (VPA), 17.3% (n = 40) on lacosamide (LCS), 16.4% (n = 38) on levetiracetam (LEV), and 13.9% (n = 32) on topiramate (TPM). The highest retention rate after 12 months since the beginning of the early adjunctive therapy was observed on CNB (92.0%), compared with LCS (80.0%), LEV (73.3%), VPA (68.2%), or TPM (62.5%) (p < 0.05). Seizure freedom and response rate were also the best on CNB (19.5% and 71.4%, respectively) compared with other ASMs (8.3% and 52.5%, respectively; p < 0.05). No significant differences in adverse events between CNB and other ASMs were observed.
Conclusions
Our study provides evidence that CNB is an effective ASM with a good safety profile in the early therapy lines of drug-resistant, focal-onset seizures. This data should support medical decision making in the management of patients with refractory epilepsy.

Binge eating disorder (BED) is the most common specific eating disorder (ED). It is frequently associated with attention deficit hyperactivity disorder (ADHD), depression, bipolar disorder (BD), anxiety disorders, alcohol and nicotine use disorder, and obesity. The aim of this narrative review was to summarize the evidence for the pharmacological treatment of BED and its comorbid disorders. We recommend the ADHD medication lisdexamfetamine (LDX) and the antiepileptic and antimigraine drug topiramate for the pharmacological treatment of BED. However, only LDX is approved for the treatment of BED in some countries. Medications to treat diseases frequently comorbid with BED include atomoxetine and LDX for ADHD; citalopram, fluoxetine, sertraline, duloxetine, and venlafaxine for anxiety disorders and depression; aripiprazole for manic episodes of BD; lamotrigine, lirasidone and lumateperone for depressive episodes of BD; naltrexone for alcohol use disorder; bupropion for nicotine use disorder; and liraglutide, semaglutide, and the combination of bupropion and naltrexone for obesity. As obesity is a frequent health consequence of BED, weight gain-inducing medications, such as the atypical antipsychotics olanzapine or clozapine, the novel antidepressant mirtazapine and tricyclic antidepressants, and the mood stabilizer valproate should be avoided where possible. It is currently unclear whether the novel and promising glucagon, glucose-dependent insulinotropic polypeptide (GIP), and glucagon-like peptide 1 (GLP-1) receptor agonists like tirzepatide and retatrutide help with BED and its comorbidities. However, these compounds have been reported to reduce binge eating in individuals with obesity or overweight.
暴饮暴食症(BED)是最常见的特殊饮食失调症(ED)。它经常与注意力缺陷多动障碍(ADHD)、抑郁症、双相情感障碍(BD)、焦虑症、酒精和尼古丁使用障碍以及肥胖症相关联。本综述旨在总结 BED 及其合并症的药物治疗证据。我们推荐多动症药物利司他敏(LDX)和抗癫痫及抗偏头痛药物托吡酯用于 BED 的药物治疗。不过,在一些国家,只有 LDX 被批准用于治疗 BED。治疗 BED 常见合并症的药物包括:治疗多动症的阿托西汀和 LDX;治疗焦虑症和抑郁症的西酞普兰、氟西汀、舍曲林、度洛西汀和文拉法辛;治疗 BD 躁狂发作的阿立哌唑;治疗 BD 抑郁发作的拉莫三嗪、利拉西酮和卢马替丙酮;治疗酒精使用障碍的纳曲酮;治疗尼古丁使用障碍的安非他酮;以及治疗肥胖症的利拉鲁肽、赛马鲁肽和安非他酮与纳曲酮的复方制剂。由于肥胖是 BED 常见的健康后果,应尽可能避免使用导致体重增加的药物,如非典型抗精神病药物奥氮平或氯氮平、新型抗抑郁药物米氮平和三环类抗抑郁药物,以及情绪稳定剂丙戊酸钠。目前还不清楚新型和前景看好的胰高血糖素、葡萄糖依赖性促胰岛素多肽(GIP)和胰高血糖素样肽 1(GLP-1)受体激动剂(如替泽帕肽和雷他曲肽)是否有助于治疗 BED 及其合并症。不过,有报道称这些化合物可减少肥胖或超重患者的暴饮暴食。

Synthetic cannabinoids are compounds made in the laboratory to structurally and functionally mimic phytocannabinoids from the Cannabis sativa L. plant, including delta-9-tetrahydrocannabinol (THC). Synthetic cannabinoids (SCs) can signal via the classical endogenous cannabinoid system (ECS) and the greater endocannabidiome network, highlighting their signalling complexity and far-reaching effects. Dronabinol and nabilone, which mimic THC signalling, have been approved by the Food and Drug Administration (FDA) for treating nausea associated with cancer chemotherapy and/or acquired immunodeficiency syndrome (AIDS). However, there is ongoing interest in these two drugs as potential analgesics for a variety of other clinical conditions, including neuropathic pain, spasticity-related pain, and nociplastic pain syndromes including fibromyalgia, osteoarthritis, and postoperative pain, among others. In this review, we highlight the signalling mechanisms of FDA-approved synthetic cannabinoids, discuss key clinical trials that investigate their analgesic potential, and illustrate challenges faced when bringing synthetic cannabinoids to the clinic.
合成大麻素是在实验室中制成的化合物,在结构上和功能上模仿来自大麻(Cannabis sativa L.)植物的植物大麻素,包括δ-9-四氢大麻酚(THC)。合成大麻素(SCs)可通过经典的内源性大麻素系统(ECS)和更大的内源性大麻素网络发出信号,突出了其信号的复杂性和深远影响。屈大麻酚和纳比隆模拟四氢大麻酚信号,已被美国食品药品管理局(FDA)批准用于治疗癌症化疗和/或获得性免疫缺陷综合征(艾滋病)引起的恶心。然而,人们对这两种药物作为潜在镇痛剂治疗其他各种临床病症的兴趣也在不断增长,包括神经性疼痛、痉挛相关疼痛、非痉挛性疼痛综合征(包括纤维肌痛、骨关节炎和术后疼痛等)。在这篇综述中,我们将重点介绍经 FDA 批准的合成大麻素的信号机制,讨论研究其镇痛潜力的主要临床试验,并说明将合成大麻素应用于临床时所面临的挑战。

A total of 334 patients were evaluated for safety [q1m, n = 172 (PY = 97.8); q2m, n = 162 (PY = 104.5)]. Proportions of patients (ER) with ≥ 1 AE and ≥ 1 treatment-related AE were 37% (180.0) and 21% (84.9) for TV-46000 q1m and 46% (157.9) and 20% (70.8) for TV-46000 q2m, respectively. Frequent treatment-related AEs [≥ 3% of patients in either group; proportion of patients (ER)] were injection site pain [q1m, 5% (24.5); q2m, 4% (22.0)] and injection site nodule [q1m, 2% (9.2); q2m, 6% (12.4)].

Background: Migraine and dizziness often coexist, with vestibular migraine (VM) presenting with vestibular symptoms and headaches. Calcitonin gene-related peptide (CGRP) may be involved in motion-induced symptoms; however, studies on the use of anti-CGRP monoclonal antibodies (mAbs) for the treatment of VM have yielded conflicting results. This study aimed to clarify the effectiveness of anti-CGRP mAbs in VM treatment.
Methods: This retrospective observational cohort study, conducted between 1 January 2021 and 31 March 2023, assessed 12 Japanese patients with VM who were treated with anti-CGRP mAbs (CGRP group) for 6 months and 11 Japanese patients who received standard of care for VM and served as controls. Clinical questionnaires and equilibrium tests were administered, with primary outcomes including changes in Dizziness Handicap Inventory (DHI) scores compared with baseline values. Objective variables included the DHI score and explanatory variables included demographic data, balance test results, head-up tilt (HUT) test results, vestibular test results and questionnaire survey results. Analysis of variance was used to assess the treatment effects of anti-CGRP mAbs, and multivariate regression analysis was performed to identify mAb responders.
Results: After 6 months, the CGRP group showed significant improvements in DHI scores [0 versus 6 months, odds ratio (95% confidence interval): 22.01 (0.13-43.88)] and number of vertigo/dizziness attacks per month [0 versus 6 months: 10.28 (2.80-17.76)]. No significant difference was observed in the control group [DHI scores, 0 versus 6 months: 0.65 (-26.84 to 28.14); number of vertigo/dizziness attacks per month, 0 versus 6 months: - 8.07 (- 23.77 to 7.62)]. Multivariate regression analysis showed that autonomic function at baseline was associated with mAb response in patients [β estimates (95% confidence interval): 3.63 (0.21-7.06)].
Conclusions: Treatment with anti-CGRP mAbs was more effective than conventional treatment in preventing migraine in patients with VM. While the identified factors associated with treatment responsiveness offer valuable insights into personalised treatment approaches, further prospective studies are warranted to validate the findings due to our study's retrospective design and limited sample size.

Alzheimer's disease (AD) is a complex multifaceted disease. Recently approved anti-amyloid monoclonal antibodies slow disease progression by approximately 30%, and combination therapy appears necessary to prevent the onset of AD or produce greater slowing of cognitive and functional decline. Combination therapies may address core features, non-specific co-pathology commonly occurring in patients with AD (e.g., inflammation), or non-AD pathologies that may co-occur with AD (e.g., α-synuclein). Combination therapies may be advanced through co-development of more than one new molecular entity or through add-on strategies including an approved agent plus a new molecular entity. Addressing add-on combination therapy is currently urgent since patients on anti-amyloid monoclonal antibodies may be included in clinical trials for experimental agents. Phase 1 information must be generated for each agent in combination drug development. Phase 2 and Phase 3 of add-on therapies may contrast the new molecular entity, the approved agent as standard of care, and the combination. More complex development programs including standard or modified combinatorial designs are required for co-development of two or more new molecular entities. Biomarkers are markedly affected by anti-amyloid monoclonal antibodies, and these effects must be anticipated in add-on trials. Examining target engagement biomarkers and comparing the magnitude and sequence of biomarker changes in those receiving more than one therapy, compared with those on monotherapy, may be informative. Using network-based medicine approaches, computational strategies may identify rational combinations using disease and drug effect network mapping.

Background and purpose: Sex is associated with clinical outcome in stroke. The present study aimed to determine the effect of sex on efficacy of dual antiplatelet (DAPT) versus alteplase in ischemic stroke based on Antiplatelet versus recombinant tissue plasminogen activator (R-tPA) for Acute Mild Ischemic Stroke (ARAMIS) trial.
Methods: In this secondary analysis of the ARAMIS study, eligible patients aged 18 years or older with minor nondisabling stroke who received dual antiplatelet therapy or intravenous alteplase within 4.5 h of stroke onset were divided into two groups: men and women. The primary endpoint was an excellent functional outcome, defined as a modified Rankin Scale (mRS) 0-1 at 90 days. Binary logistic regression analyses and generalized linear models were used.
Results: Of the 719 patients who completed the study, 31% (223) were women, and 69% (496) were men. There were no significant sex differences in excellent functional outcome (unadjusted p = 0.304 for men and p = 0.993 for women; adjusted p = 0.376 for men and p = 0.918 for women) and favorable functional outcome (mRS score of 0-2; unadjusted p = 0.968 for men and p = 0.881 for women; adjusted p = 0.824 for men and p = 0.881 for women). But for the secondary outcomes, compared with alteplase, DAPT was associated with a significantly decreased proportion of early neurological deterioration within 24 h in men {unadjusted odds ratio [OR] = 0.440 [95% confidence interval (CI), 0.221-0.878]; p = 0.020; adjusted OR = 0.436 [95% CI, 0.216-0.877]; p = 0.020}, but not in women [unadjusted OR = 0.636 (95% CI, 0.175-2.319), p = 0.490; adjusted OR = 0.687 (95% CI, 0.181-2.609), p = 0.581]. For the safety outcomes, compared with the DAPT group, alteplase was associated with a significantly increased proportion of any bleeding events in men [unadjusted OR = 3.110 (95% CI, 1.103-8.770); p = 0.032], but not in women [unadjusted OR = 5.333 (95% CI, 0.613-46.407), p = 0.129; adjusted OR = 5.394 (95% CI, 0.592-49.112), p = 0.135].
Conclusion: Sex did not influence the effect of dual antiplatelet therapy versus intravenous alteplase in minor nondisabling stroke, but more early neurological deterioration and bleeding events occurred in men who received alteplase.
背景和目的:性别与中风的临床预后有关。本研究旨在根据急性轻度缺血性卒中抗血小板与重组组织纤溶酶原激活剂(R-tPA)试验(ARAMIS)确定性别对缺血性卒中双联抗血小板(DAPT)与阿替普酶疗效的影响:在这项 ARAMIS 研究的二次分析中,符合条件的 18 岁及以上非致残性轻微脑卒中患者在脑卒中发生后 4.5 小时内接受了双联抗血小板疗法或静脉注射阿替普酶后,被分为两组:男性组和女性组。主要终点是良好的功能预后,即 90 天时改良 Rankin 量表(mRS)为 0-1。研究采用了二元逻辑回归分析和广义线性模型:在完成研究的 719 名患者中,31%(223 人)为女性,69%(496 人)为男性。在优良功能预后(未经调整的男性 p = 0.304,女性 p = 0.993;调整后男性 p = 0.376,女性 p = 0.918)和良好功能预后(mRS 评分 0-2 分;未经调整的男性 p = 0.968,女性 p = 0.881;调整后男性 p = 0.824,女性 p = 0.881)方面没有明显的性别差异。但就次要结果而言,与阿替普酶相比,DAPT与男性24小时内早期神经功能恶化的比例显著降低相关{未经调整的几率比[OR] = 0.440 [95% 置信区间 (CI),0.221-0.878];p = 0.020;调整后 OR = 0.436 [95% CI,0.216-0.877];p = 0.020},但在女性中没有相关性[未调整 OR = 0.636 (95% CI,0.175-2.319),p = 0.490;调整 OR = 0.687 (95% CI,0.181-2.609),p = 0.581]。在安全性结果方面,与DAPT组相比,阿替普酶与男性[未调整OR = 3.110 (95% CI, 1.103-8.770); p = 0.032]显著增加的任何出血事件比例相关,但与女性[未调整OR = 5.333 (95% CI, 0.613-46.407), p = 0.129; 调整OR = 5.394 (95% CI, 0.592-49.112), p = 0.135]无关:性别并不影响双联抗血小板疗法与静脉注射阿替普酶治疗轻度非致残性卒中的效果,但接受阿替普酶治疗的男性患者早期神经功能恶化和出血事件发生率更高。

Anhedonia, a complex symptom rooted in deficits across reward processes, is primarily linked to depression and schizophrenia but transcends diagnostic boundaries across various mental disorders. Its presence correlates with poorer clinical outcomes, including an increased risk of suicide and diminished response to treatment. The neurobiological underpinnings of anhedonia remain incompletely understood despite advancements in biomarkers and imaging that contribute to deeper insights. Ketamine, known for its rapid-acting antidepressant properties, appears to possess antianhedonic effects through a mechanism of action not fully elucidated. This effect appears to be independent of its antidepressant properties. Explorations into alternative antianhedonic treatments have been underway, yet lingering questions persist, underscoring the imperative need for ongoing research to advance the field.

The US Food and Drug Administration (FDA) approval of lecanemab for early-stage Alzheimer's disease (AD) represents an exciting new chapter in the management of neurodegenerative disease, but likewise presents numerous clinical, technical, and financial logistical challenges for both academic and non-academic medical institutions hoping to administer this drug. Minimal resources exist that provide guidance for establishing and maintaining a lecanemab treatment program at the institutional level. The current report aims to provide healthcare institutions a framework for the planning, onboarding, and longitudinal treatment of AD with anti-amyloid monoclonal antibody treatments. We present an implementation study involving three stages: (1) feasibility assessment, (2) operations and going live, and (3) monitoring assessment. We found that implementation of lecanemab in clinical practice was feasible due to the assignment of an enterprise-wide project manager to facilitate the planning phase, a cost analysis showing that lecanemab was financially sustainable, and the development of electronic medical record tools to support operational efficiency.

BACKGROUND AND OBJECTIVES: Clozapine is the medication of choice for treatment-resistant schizophrenia. However, it has a complex metabolism and unexplained interindividual variability. The current work aims to develop a pharmacokinetic model of clozapine and norclozapine in non-smokers and assess the impact of demographic and genetic predictors.
Methods: Healthy volunteers were recruited in a population pharmacokinetic study. Blood samples were collected at 30 min and 1, 2, 3, 5 and 8 h following a single flat dose of clozapine (12.5 mg). The clozapine and norclozapine concentrations were measured via high-performance liquid chromatography-ultraviolet method. A semi-physiological pharmacokinetic model of clozapine and norclozapine was developed using nonlinear mixed-effects modeling. Clinical and genetic predictors were evaluated, including CYP1A2 (rs762551) and ABCB1 (rs2032582), using restriction fragment length polymorphism.
Results: A total of 270 samples were collected from 33 participants. The data were best described using a two-compartment model for clozapine and a two-compartment model for norclozapine with first-order absorption and elimination and pre-systemic metabolism. The estimated (relative standard error) clearance of clozapine and norclozapine were 27 L h-1 (31.5 %) and 19.6 L h-1 (30%), respectively. Clozapine clearance was lower in sub-Saharan Africans (n = 4) and higher in Caucasians (n = 9) than Asians (n = 20). Participants with CYP1A2 (rs762551) (n = 18) and ABCB1 (rs2032582) (n = 12) mutant alleles had lower clozapine clearance in the univariate analysis.
Conclusions: This is the first study to develop a semi-physiological pharmacokinetic model of clozapine and norclozapine accounting for the pre-systemic metabolism. Asians required lower doses of clozapine as compared with Caucasians, while clozapine pharmacokinetics in sub-Saharan Africans should be further investigated in larger trials.
