Purpose: About 6.4% of the U.S. population suffers from posttraumatic stress disorder (PTSD). Trauma-focused psychotherapies are generally effective in PTSD, but responses vary greatly across individuals and PTSD subpopulations. Neurobiological factors impacted by life experiences, stress, and genetics can affect treatment responses. These factors can alter brain capacities needed to reprocess traumatic memories prevent them from triggering intensely distressing, disruptive, out-of-place responses.
For example, during psychotherapy for PTSD, trauma memory activation engages two competing brain processes that affect recovery: "extinction" versus "reconsolidation" of trauma-related emotional, physiological, and behavioral responses. This study tests whether a single intravenous (IV) dose of allopregnanolone (Allo) compared to placebo (which is non-active): promotes consolidation of extinction learning (sub-study 1) or blocks reconsolidation of physiological responses triggered by aversive memories (sub-study 2). The study also tests whether Allo compared to placebo affects retention of non-aversive memories.

Early postnatal inhibition of neurosteroid synthesis changes the later-life adverse outcome of neonatal asphyxia in rats

Article

作者: Löscher, Wolfgang ; Welzel, Björn ; Schmidt, Ricardo

Birth asphyxia (BA) is a common cause of hypoxic-ischemic encephalopathy (HIE), neonatal seizures, and detrimental neurodevelopment. Brain levels of neurosteroids such as allopregnanolone rise in response to acute hypoxic stress, which is thought to represent an endogenous protective mechanism that reduces excitotoxicity in the developing brain. In the present study, we investigated how inhibition of neurosteroid synthesis by the steroid 5α-reductase inhibitor finasteride affects the adverse outcomes of BA/HIE. Intermittent asphyxia was induced in neonatal rats at postnatal day 11. Finasteride (50 mg/kg) was administered immediately before asphyxia. Behavioral and cognitive tests were performed over the subsequent 14 months, which corresponds to ∼50 % of the lifespan of the outbred rat strain used. In contrast to our expectation, finasteride decreased the severity and duration of the neonatal seizures and did not increase mortality. Subsequent behavioral experiments showed no adverse development of motor function, but finasteride-treated rats exhibited increased anxiety-like behavior in the open field, elevated plus-maze, and light-dark box tests. The increased anxiety-like behavior was correlated with enhanced mossy fiber sprouting in the hippocampal CA3a region. While vehicle-treated post-asphyxial rats showed a serious decline in cognitive functions, this was not observed in the finasteride-treated group. One possible explanation of the latter finding is that a significant loss of CA3c neurons in the dorsal hippocampus was only determined in vehicle-treated but not finasteride-treated post-asphyxial rats. Overall, the present study indicates that the role of neurosteroids in BA and its adverse outcome is much more complex than previously thought.

A systematic analysis of safety profile of Brexanolone in real-world use based on FAERS database

Article

作者: Zhu, Haohao ; Lu, Rongrong ; Jiang, Ying ; Wang, Shuai ; Du, Zhiqiang ; Gao, Xuezheng

OBJECTIVE:

This study aims to analyze adverse events (AEs) associated with Brexanolone based on FAERS, to assess its real-world safety characteristics, and to explore potential underlying mechanisms.

METHODS:

Data from the FAERS database since Brexanolone's approval in 2019 were extracted, categorizing and analyzing AEs based on frequency and signal strength. Signal detection was conducted using frequency and Bayesian methods to assess the statistical association between AEs and Brexanolone.

RESULTS:

A total of 234 Brexanolone-related AE reports were collected. Signal detection results revealed a significant association between Brexanolone and multiple system-organ AEs. Intravenous infusion-related events were notably frequent, including Product Administration Error (35 cases), Incorrect Drug Monitoring Procedure (19 cases), Product Administration Interrupted (14 cases), Incorrect Product Administration Duration (11 cases), and Medication Error (10 cases). These findings indicate a need for more standardized management of Brexanolone administration in clinical practice. Common psychiatric AEs were identified, including Perinatal Depression, Intrusive Thoughts, Electroencephalogram Abnormality, Panic Disorder, Tearfulness, Self-Injurious Ideation, Sedation Complication, and Feelings of Despair. Of these, Tearfulness, Self-Injurious Ideation, Sedation Complication, Feelings of Despair, and Crying are known AEs of Brexanolone. Signal strengths for Perinatal Depression, Intrusive Thoughts, Electroencephalogram Abnormality, and Panic Disorder indicate new potential AEs.

CONCLUSION:

The introduction of Brexanolone has brought new hope to postpartum depression treatment, yet the study identifies a range of AEs, particularly associated with intravenous infusion and mental status changes, emphasizing caution in clinical application.

Inhibition of xanthine oxidoreductase with febuxostat, but not allopurinol, prevents inflammasome assembly and IL-1β release

Article

作者: Archambault, Anne-Sophie ; Rakić, Bojana ; Dubland, Joshua A ; Starchuk, Lucas F ; Verchere, C Bruce ; Alcazar, Armando ; de Brito Monteiro, Lauar ; Klein Geltink, Ramon I ; Oh, Ju Hee ; Patterson, Annette E

Xanthine oxidoreductase (XOR) inhibitors are used to treat gout, inhibiting uric acid production, which causes clinical symptoms. Commonly used XOR inhibitors are the small molecule febuxostat (Fbx) and the purine analogue allopurinol (Allo). Recent studies show that XOR inhibitors can reduce mature interleukin (IL)-1β production by activated macrophages. This effect is not due to reduced uric acid crystal formation, which can induce NLRP3 inflammasome activation, but an independent effect. Fbx and Allo have been used interchangeably in in vitro studies to highlight the role of XOR in pro-inflammatory macrophage function. Here, we analysed the effects of Fbx and Allo on pro-inflammatory macrophage signatures. Both XOR inhibitors maintain pro-inflammatory macrophage metabolic and phenotypic hallmarks. However, only Fbx reduces the activity of caspase-1 and the release of IL-1β by preventing inflammasome assembly in macrophages isolated from both mice and humans. Our study identified an Fbx-specific reduction in IL-1β production, which could be used clinically to reduce the deleterious effects of macrophage-derived IL-1β.

MAOIs）、三环类药物（tricyclic antidepressants, TCAs）、γ- 氨基丁酸(γ-aminobutyric acid, GABA）/ 谷氨酸能药物及其他新靶点药物的不断涌现，为抑郁症患者提供了更多治疗选择。综述近几年抗抑郁药的临床研发现状及全球管线情况，通过对不同靶点抗抑郁药的临床意义、市场现状、研发格局及在研管线的详细分析，旨在为相关研究人员和临床医生提供参考。抗抑郁药的研究与开发一直备受关注。从最初偶然发现的初代抗抑郁药如单胺氧化酶抑制剂（monoamine oxidase inhibitors，MAOIs）和三环类药物（tricyclic antidepressants，TCAs），到基于抑郁症致病机制和分子生物学研究设计的选择性 5-羟色胺再摄取抑制剂（selective serotonin reuptake inhibitors ， SSRIs）以及 5-羟色胺（5-hydroxytryptamine，5-HT ）和去甲肾上腺素抑制剂（serotonin and norepinephrine reuptake inhibitors ，SNRIs）等，再到作用于谷氨酸能和 γ-氨基丁酸( γ-aminobutyric acid ，GABA）靶点的速效抗抑郁药，抗抑郁药的作用靶点和机制探索日趋丰富。理解不同靶点生理作用及其临床意义，不仅可深化对抑郁症的病理机制的了解、优化临床用药的实践，更有助于开发在疗效和安全耐受性方面更具优势的创新抗抑郁药。本文综述了近几年抗抑郁药的临床研发现状及管线情况，通过对不同靶点抗抑郁药的临床意义、市场现状、研发格局及在研管线的详细分析，旨在为相关研究人员和临床医生提供参考。1 抗抑郁药的靶点与临床意义1.1 单胺氧化酶抑制剂与三环类抗抑郁药MAOIs 和 TCAs 是最早开发和使用的抗抑郁药物，其核心作用机制均通过非选择性调控单胺递质系统达到抗抑郁效果[1] 。然而，MAOIs 和 TCAs 的非选择性的多靶点特性导致疗效与风险并存。MAOIs 通过抑制脑内单胺神经递质的代谢提高突触递质浓度，发挥抗抑郁作用。该类药物“广谱增效”的特点使其在治疗顽固性抑郁症及伴焦虑与疼痛的复杂型抑郁症具有独特的优势。然而， MAOIs 的缺点也较明显，如服用 MAOIs 的患者需要避免摄入富含酪胺的食物（如陈年奶酪、红酒、腌制肉类等），因可能会引发严重的高血压反应，其次 MAOIs 与其他药物，包括一些常见的非处方药和处方药有潜在危险的相互作用，这要求患者在使用其他药物前必须咨询医生。此外， MAOIs 常见的不良反应还包括睡眠障碍、恶心和头晕等，非选择性的 MAOIs 还有导致直立性低血压的风险 [2]。上述因素限制了MAOIs 的临床使用，使其逐步退居为二线用药。TCAs 通过抑制去甲肾上腺素（norepinephrine， NE）和 5-HT 的再摄取过程，增强神经递质的可利用性。TCAs 的优势在于治疗慢性和重度抑郁症的效果更好，特别是对于复杂的抑郁症病例可能较有效。然而，TCAs 对 α1 肾上腺素受体、毒蕈碱性乙酰胆碱受体及钠离子通道的拮抗和调节作用，可能导致抗胆碱能反应（口干、便秘）和心脏毒性问题突出，严重时甚至危及生命 [3] ，提示临床医生在开具处方时需谨慎评估患者的健康状况和使用风险。与新型抗抑郁药物相比，TCAs 往往需要更长时间才会显现疗效，对于亟待缓解症状的患者而言可能不理想。1.2 单胺类抗抑郁药基于单胺假说的深入发展，抑郁症被认为是脑内 5-HT、NE 和多巴胺（dopamine，DA）水平失衡所导致的结果。SSRIs 和 SNRIs 是目前临床上最常用的单胺类抗抑郁药。SSRIs 通过选择性阻断突触前 5-HT 转运蛋白来发挥其治疗作用。相较于 MAOIs 和 TCAs ，SSRIs 的靶点精确定位实现了安全性突破，不良反应的发生频率和严重程度均大幅降低，对于孕妇和老年人等脆弱人群也较为安全。然而 SSRIs 也存在临床局限性：1)起效慢，可能需要数周才能显示出显著的抗抑郁效果。2)存在 5-HT 综合征风险，可能引起锥体外系症状，还会导致恶心、胃肠道反应和性功能障碍等不良反应。3)SSRIs 可能导致药物间相互作用，突然停用 SSRIs 可能诱发停药综合征，出现头痛、眩晕、情绪波动等症状，因此需要逐渐减量。SNRIs 通过协同调节 5-HT 和 NE 通路，其疗效谱系更广。对于 SSRIs 疗效欠佳的抑郁症患者，可从 SNRIs 治疗中获益。相较于 SSRIs ，SNRIs 及其代谢物对 CYP 酶的影响较低，不易产生严重的药物间相互作用。此外，SNRIs 和 TCAs 均可同时影响 5-HT 和 NE 通路，二者对抑郁症相关疼痛症状的疗效相似，但 SNRIs靶点选择度更高，不良反应更少。SNRIs 引起的不良反应与剂量有关，低剂量下 SNRIs 主要阻断 5-HT 再摄取，因此不良反应表现与 SSRIs 相似；中至高剂量下，SNRIs 对 5-HT 和 NE 再摄取均有阻断效果，因阻断 NE 再摄取而产生的不良反应包括出汗、心动过速、震颤、焦虑和高血压等。提示，未来抗抑郁药物研发需突破“单纯递质浓度调节”的局限，转向受体亚型特异性调控从而实现精准干预。除 SSRIs 和 SNRIs 外，还有一些作用于单胺神经递质通路但具体靶点不同的药物（见表1），其中部分药物对于特殊人群（如急性期患者、老年患者）具有更好的疗效，且不良反应相对更少。1.3 γ- 氨基丁酸/谷氨酸能抗抑郁药研究发现，抑郁症不仅与单胺神经递质有关，还涉及大脑、脑脊髓液和外周组织中其他神经递质的紊乱 [4] 。GABA 和谷氨酸是大脑中2 种重要的神经递质。GABA 是中枢神经系统的主要抑制性神经递质，GABA 合成减少或受体活性减退可导致神经元过度兴奋，影响情绪与认知。谷氨酸是主要的兴奋性神经递质，参与学习、记忆和神经可塑性。GABA/ 谷氨酸能抗抑郁药物直接作用于大脑中的关键神经递质系统，能够迅速调节神经元的活动，增强突触可塑性，促进新的神经连接的形成，从而快速改善情绪 [5] 。这些药物可通过静脉注射、鼻腔喷雾等多种途径给药，增加其使用的灵活性，如艾司氯胺酮通过鼻喷雾剂途径给药，在起效速度方面的临床优势显著，对于急需快速缓解症状的患者，尤其是有自杀风险的患者，具有重要的临床意义 [6-7]。然而，需警惕氯胺酮的分离性幻觉要求严格用药监护，长期神经可塑性改变的安全性仍需验证。提示，新一代抗抑郁药的研发需在“快速起效”与“长期安全”间寻求平衡。此外，对于一些特殊患者群体，如对传统抗抑郁药物反应不佳的难治性抑郁症患者及患有产后抑郁的妇女，GABA/谷氨酸能抗抑郁药提供了一种新的治疗选择。2019 年美国食品药品监督管理局（Food and Drug Administration，FDA）批准了一款突破性产品别孕烯醇酮用于治疗产后抑郁症。别孕烯醇酮通过静脉输注给药，通过正向调节 GABAA 受体，降低焦虑水平并减轻抑郁症状。一项针对哺乳期健康受试者的 Ⅰb 期临床研究表明，别孕烯醇酮给药后，四氢孕酮在血浆和母乳中的水平可被快速清除，对婴儿影响较小，实现了母婴安全性平衡 [8]。2抗抑郁药物市场现状根据最新的市场报告，全球抗抑郁药物市场在 2024 年的规模约为171.1 亿美元，将以 4.2% 的复合年增长率在 2025 年增长至 178.2 亿美元；预计抗抑郁药市场规模将在未来几年稳步增长，到 2029 年市场规模预计将达到 202.5 亿美元 [9]。自 2019 年 2 个里程碑式的产品艾司氯胺酮和别孕烯醇酮在美国上市，全球抗抑郁创新药上市速度明显加快，机制靶点和上市地区也更加丰富。2022—2023 年全球共有5 个抗抑郁新药上市（见表2）。吉哌隆是首款治疗成人抑郁症的口服选择性 5-HT1A 受体激动剂，自 2002 年起曾被美国FDA 拒绝上市申请多次，如今终获批准。舒拉诺龙是首个获批治疗产后抑郁症的口服药物，可在3天内改善症状，比目前用于治疗产后抑郁症的抗抑郁药起效更快 [10] 。舒拉诺龙的获批，标志着目前产后抑郁症的治疗模式发生了重大变化。肠道益生菌 Mokbio® 可通过调节肠道菌群平衡来减少抑郁症状 [11] 。 Auvelity®（安非他酮 + 右美沙芬）是美国 FDA 批准的首个口服速效抗抑郁药，在该复方制剂的组合中，右美沙芬主要作为 N-甲基-D-天冬氨酸受体（N-methyl-D-aspartic acid receptor，NMDAR）拮抗剂，安非他酮可增加右美沙芬的生物利用度，同时抑制 NE 和 DA 再摄取 [12] 。中国也上市了 5-HT/NE/DA 三重再摄取抑制剂若欣林 ®（托鲁地文拉法辛）[13] 。若欣林 ® 作为首款国产 1 类创新抗抑郁药，为在创新药领域积极探索的本土企业增加了信心，标志着我国从“快速跟随”向“自主创新”的战略转型。基于全球抗抑郁市场的逐渐活跃，中国抗抑郁药市场也呈现诸多积极的态势。在创新药领域，跨国企业已开始注重在中国的布局，如艾司氯胺酮于 2019 年在美国获批，2023 年即在中国上市。此外，中国本土企业除积极探索创新产品外，也在快速抢占抑郁症仿制药的市场，多个未在中国上市的创新产品的仿制药已获批或进入临床试验。3抗抑郁新药的研发格局截至 2024 年 6 月，全球处于在研状态（近 3 年内存在临床试验记录）的抗抑郁症创新药共计 77 个，约 2/3 的管线处于Ⅱ期临床试验阶段（见表 3）。与过去单胺类主导的研发模式不同，当前抗抑郁症创新药管线呈现“单胺深化 + 多靶点突破”的双轨格局。56% 的管线仍聚焦单胺及 GABA/ 谷氨酸通路，其余管线则探索阿片受体（opioid receptor ，OR）和食欲素受体（orexin receptor ，OX ）等新靶点。基于近几年抑郁症分子病因学的发展，全球有 19 个管线作用于常见神经递质和受体之外的新靶点，甚至涉及神经可塑性、炎症调控等新兴机制。另外，氘代技术通过稳定代谢路径，可延长药物半衰期、减少副作用，成为老药优化的新方向。4在研抗抑郁新药管线分析4.1作用于 GABA/ 谷氨酸能神经递质的抗抑郁药传统抗抑郁药多聚焦单胺靶点，而目前作用于氨基酸神经递质系统（GABA 和谷氨酸）的抗抑郁药是研发管线的热门，共有 18 个在研产品，其中有 6 个在中国进行研发（见表4）。传统单胺类药物（如 SSRIs）需 2~4 周起效，而 GABA/ 谷氨酸能药物（如氯胺酮）通过调节谷氨酸能突触可塑性在临床应用中可以实现快速（数小时内）抗抑郁，然而，其致幻性和成瘾性风险催生了对其结构优化和剂型创新等策略。例如，具有口服活性的氯胺酮结构类似物 GM1020 通过结构修饰，避免了静脉注射氯胺酮和艾司氯胺酮相关的不良反应，已针对重度抑郁症进行了Ⅱ期临床研究。新型长效注射剂通过剂型创新，可实现单次肌肉注射给药用于产后抑郁，提高用药的依从性和便利性，低口服生物利用度避免了母婴暴露，兼顾疗效与安全性。另外，值得关注的是，在靶向 GABAA 的管线中 PRAX 114 已进展到Ⅱ/Ⅲ期临床阶段，但在近期 Aria 研究中，尽管 PRAX-114 显示耐受性良好，但其疗效未能满足患者的需求，在主要终点上未达到统计学意义 [14] ，提示单纯增强 GABA 能活性可能不足以应对抑郁症的多维度病理，需结合其他通路调节。4.2 作用于单胺神经递质的抗抑郁药目前，全球单胺神经递质靶点相关在研抗抑郁药共 25 个，其中 32% 在中国开展研发（见表 5 ）。根据多靶点协同调控策略研发的药物包括 5-HT/ NE/DA 三重再摄取抑制剂 DB-104（liafensine）、 EB-1020 、OPC-64005 、JS1-1-01 以及 5-HT/NE 双重再摄取抑制剂 NH-102 等，此类药物通过协同调节不同递质系统，在临床应用中可能覆盖更广泛的症状谱，如情感麻木、快感缺失、认知障碍等。除上述多靶点策略外，致幻剂衍生药物的研究开创了 “快速抗抑郁 + 神经重塑”的路径。例如 ELE-101 通过 5-HT2A 受体部分激动/拮抗的分子设计，在保留裸盖菇素快速抗抑郁活性的同时，显著降低致幻作用。类似地，SPL-026 也是通过修饰二甲氧基色胺的侧链保留了抗抑郁活性的同时，减少了幻觉发生。目前国内外研究者正积极探索分子修饰策略，在保留致幻剂快速抗抑郁效果的同时，降低其致幻副作用 [15-16]。目前处于Ⅲ期临床阶段的单胺神经递质靶点抗抑郁药共有 3 个。Ulotaront 是一款具有 5-HT1A 激动剂活性的痕量胺相关受体 1（trace amine-associated receptor 1 ，TAAR1 ）激动剂，目前正在美国进行针对重度抑郁症的辅助性治疗的Ⅱ/Ⅲ期临床研究，其独特的机制可能为患者提供更有效的治疗选择，预计其研究结果将于 2025 年公布。嘧替佐酮是国内在研该类药物中进展最快的产品之一，自 2021 年7月启动Ⅱ/Ⅲ期临床研究以来，已取得显著进展，其快速的研发速度和潜在的疗效，使其备受关注。4.3 作用于阿片受体和食欲素受体的抗抑郁药除单胺类及 GABA/谷氨酸能系统等经典通路外，OR 和 OX 等新型神经递质受体在抑郁症病理生理中的作用正受到日益关注。OR 可通过异二聚化（heterodimerization）与 5-HT 和 DA 受体在功能上产生相互作用 [17] ，负向调节神经递质的释放 [18] 。临床前和临床研究表明， OR 系统通过调节社交行为、食欲、快感体验、奖赏机制及焦虑反应等多维度影响抑郁发生 [19] 。目前全球作用于 OR 的抗抑郁药管线有 3 个（见表6），其中短效 kappa 型阿片受体（kappa opioid receptor， KOR）拮抗剂 aticaprant 研究进展最快，已在全球开展针对抑郁症、快感缺失、焦虑障碍等适应证Ⅰ~ Ⅲ 期临床试验，并于 2023 年初获得中国Ⅲ期临床试验的默示许可，显示出其在精神治疗领域的广泛应用潜力。OX 是重要的神经肽类递质，除调控与抑郁密切相关的睡眠-觉醒、摄食等生理过程外，还可通过双向调节多个脑区的活动直接影响抑郁状态 [20] 。早在 2012 年进行的双重 OX 拮抗剂 filorexant 随机、双盲、对照Ⅱ期临床试验，受试者招募困难，且治疗组和安慰剂组的抑郁量表评分未能达到统计学意义上的差异 [21] 。目前在研的 2 个 OX 拮抗剂（见表6）转向选择性拮抗治疗策略，其中，选择性人类食欲素-2（orexin-2 ，OX2 ）受体拮抗剂 seltorexant 在 Ⅲ期临床试验 MDD3001 中，作为抗抑郁药的辅助治疗显示出显著的有效性和安全性，尤其对伴有失眠症状的抑郁症患者疗效显著，有望成为“first-in- class”的选择性 OX2 受体拮抗剂 [22]。4.4 其他新靶点抗抑郁药抑郁症的分子病因学和病理生理学机制复杂，受到遗传和环境等因素相互作用的影响。近年来，不同分子水平的大量研究发现，除了单胺和谷氨酸能神经递质及其传导机制外，抑郁症还与一系列人体和环境因素密切相关，如压力水平、神经系统发育、神经营养因子、表观遗传、免疫系统和炎症、肠道菌群等 [23-24]。这些因素中的许多已成为抗抑郁新药研发的新靶点，为抗抑郁药物的临床研发提供了新方向 [25] 。表7列举了全球范围内针对这些新靶点的19个抗抑郁药的临床研发管线，其中，Xanamem®和TS-121通过降低压力水平来缓解抑郁症状；ALTO-100通过增强神经营养因子效能促进神经网络重构；BI-1358894借助神经元离子通道调节改善突触传递；ZZ-2103通过调节肠道迷走神经信号改善中枢神经功能；MET-2靶向肠道微生物生态系统重塑等。目前，这些针对新靶点的抗抑郁药物中 68% 处于Ⅱ期临床试验阶段，显示出良好的临床应用前景。4.5 氘代抗抑郁药氘代药物作为一种新兴的药物研发方向，凭借其独特的同位素效应，在抗抑郁药物的开发中展现出广泛的应用潜力。目前，全球范围内有6个临床在研的氘代抗抑郁药物，其中有 2 个由中国本土企业在中国进行临床研发（见表8）。氘代技术通过选择性替换药物分子中的氢原子为氘原子（D），显著提高了药物在体内的代谢稳定性，延长了药物半衰期和生物利用度，进而增强了药物的安全性、耐受性和疗效 [26-28] 。氘代技术在保留原药药理活性的基础上，通过改变代谢路径选择性降低毒性中间体生成，达成“代谢分流” 与“毒性隔离”的双重优化目标，实现“老药新用” 的迭代升级，不仅减少了相关的药物不良反应，还极大地提升了患者在治疗过程中的用药体验。5结语与展望综上所述，抗抑郁药物的研发在过去几年中取得了显著进展，单胺类药物、GABA/谷氨酸能药物及其他新靶点药物的不断涌现，为抑郁症患者提供了更多的治疗选择。全球抗抑郁药物市场在创新驱动下保持稳健增长，新型药物上市周期明显缩短、作用靶点呈现多维度突破、治疗机制实现多元化创新。这标志着抗抑郁药研发已突破传统“单胺假说” 的理论框架，正式迈入多靶点协同、多模态干预的新时代。相较于传统药物，新型抗抑郁药物在起效速度、适应证覆盖和机制创新等方面取得突破性进展。然而，现有药物体系仍面临临床疗效个体差异显著、远期安全性数据不足等关键挑战，提示需建立更精准的生物标志物评价体系。未来，随着分子病因学和病理生理学研究的深入，更多具有创新靶点的抗抑郁药物有望进入临床应用。特别是在中国，随着本土企业在创新药物研发方面的积极探索和跨国企业的布局，中国抗抑郁药物市场将迎来更多机遇和挑战，中国药企需加强源头创新（如氘代技术、人工智能辅助药物设计等）并进一步深化临床转化研究。期待未来能有更多高效、安全的抗抑郁药物成功问世，为全球抑郁症患者带来康复的希望。参考文献：[1]

Seaport Therapeutics Announces First Patient Dosed in Phase 2b BUOY-1 Study of GlyphAllo ™ (SPT-300) in Major Depressive Disorder (MDD), With or Without Anxious Distress

BOSTON--(BUSINESS WIRE)--Seaport Therapeutics (“Seaport” or the “Company”), a clinical-stage biopharmaceutical company that is advancing novel neuropsychiatric medicines with a proven strategy and team, today announced that the first patient has been dosed in the Phase 2b BUOY-1 study of GlyphAlloTM (SPT-300 or Glyph Allopregnanolone) in major depressive disorder (MDD) with or without anxious distress. GlyphAllo is a novel, “Glyphed” oral prodrug of allopregnanolone, an endogenous molecule that has been shown to dampen stress. Allopregnanolone has been clinically validated in third-party trials as a rapidly acting antidepressant with anxiolytic effects, but its scope of clinical use was previously constrained by limitations that the GlyphTM platform is specifically designed to solve. GlyphAllo has the potential to be a first-in-class treatment for patients with MDD, including those with or without anxious distress. “The initiation of BUOY-1 marks a significant milestone for Seaport’s pipeline, bringing us closer to a potential new treatment for major depression, which impacts around 280 million people globally – nearly 60 percent of whom also experience anxious distress,” said Daphne Zohar, Co-Founder and Chief Executive Officer at Seaport Therapeutics. “This is an important step on our journey to deliver new treatments for patients living with depression, anxiety, and other neuropsychiatric conditions.” BUOY-1 is a global, randomized, double-blind, placebo-controlled study that will evaluate the efficacy, safety, and tolerability of GlyphAllo in adults with MDD, with or without anxious distress, a subtype of depression characterized by significant anxiety. The study is expected to enroll up to approximately 360 patients, randomized 1:1 to receive either GlyphAllo or placebo once-daily over a six-week treatment period. The primary endpoint of the study is the change from baseline at six weeks in the Hamilton Depression Rating Scale-17 (HAM-D-17), a gold-standard depression severity rating scale. Following the initial treatment period, eligible patients may enter an open-label extension phase, during which all participants will receive GlyphAllo for up to an additional six weeks. “CNS clinical trials are inherently complex, and we are applying our team’s extensive expertise to implement a high-quality study,” said Antony Loebel, M.D., Chief Medical Officer, President of Clinical Development at Seaport Therapeutics. “We are confident that our rigorous clinical trial execution, including an emphasis on the quality of patient enrollment, will build on a proven mechanism and established clinical efficacy, to increase our likelihood of success in developing an effective treatment for patients with depression." The BUOY-1 study builds on a foundation of positive clinical data from Phase 1 and Phase 2a studies of GlyphAllo in healthy volunteers. In Phase 1, GlyphAllo demonstrated approximately nine times greater allopregnanolone exposure than that previously reported following oral dosing of allopregnanolone and reached similar exposures to the efficacious doses of IV-infused allopregnanolone. The two key measures used to determine allopregnanolone-associated brain activity, EEG beta frequency power and reduction in saccadic eye velocity, confirmed that GlyphAllo engaged with its target in a dose-dependent manner. The overall safety data, pharmacokinetics, and pharmacodynamic findings, along with non-clinical studies, support six-week dosing of GlyphAllo in BUOY-1. In a Phase 2a proof-of-concept study in healthy volunteers using the Trier Social Stress Test (TSST), a validated clinical model of anxiety, GlyphAllo significantly reduced the stress hormone salivary cortisol at all post-TSST timepoints compared to placebo, meeting the primary endpoint with a p-value of 0.0001 and demonstrating that GlyphAllo regulates hypothalamic-pituitary-adrenal axis reactivity to acute stress. GlyphAllo was generally well-tolerated, with adverse events that were mostly mild and transient. About the GlyphTM Platform Glyph is Seaport’s proprietary technology platform which uses the lymphatic system to enable and enhance the oral administration of drugs. With the Glyph platform, drugs are absorbed like dietary fats through the intestinal lymphatic system and transported into circulation. The Glyph platform has the potential to be widely applied to many therapeutic molecules that have high first-pass metabolism otherwise leading to low bioavailability and/or side effects, including liver enzyme elevations or hepatotoxicity. For each program, Seaport leverages its Glyph platform to create unique sets of prodrugs with differentiated profiles, including lymphatic transport and conversion characteristics, as potential candidates to advance into preclinical and clinical proof-of-concept studies. Seaport exclusively licensed this technology from Monash University based on the pioneering research of the Porter Research Group. Advanced initially at PureTech Health and now at Seaport, Glyph has been applied to create therapeutic candidates for the Company’s pipeline resulting in new intellectual property, including composition of matter. The group and its collaborators have published research in Nature Metabolism, Frontiers in Pharmacology, Journal of Controlled Release and Molecular Pharmaceutics supporting the Glyph platform’s capabilities. See Glyph in action here. About GlyphAlloTM (SPT-300 or Glyph Allopregnanolone) GlyphAllo (SPT-300 or Glyph Allopregnanolone), an oral prodrug of allopregnanolone, is in clinical stage development for the treatment of major depressive disorder (MDD) with or without anxious distress. Allopregnanolone, an endogenous molecule that has been shown to dampen stress, has antidepressant and anxiolytic activity and sleep-promoting effects but poor oral bioavailability due to substantial first-pass hepatic metabolism. Allopregnanolone was previously only approved as an intravenous infusion, which limited the scope of its clinical use. A synthetic analog of allopregnanolone was previously evaluated in MDD and showed promise but may not retain the activity, potency and the breadth of the natural biological response of endogenous allopregnanolone. In a Phase 1 clinical study, GlyphAllo demonstrated oral bioavailability, tolerability and γ-aminobutyric-acid type A (GABAA) receptor target engagement in healthy volunteers. In a Phase 2a clinical study, GlyphAllo demonstrated initial proof-of-concept in the Trier Social Stress Test, a validated clinical model of anxiety in healthy volunteers. GlyphAllo is currently being evaluated in the Phase 2b BUOY-1 study for MDD, with or without anxious distress. About Seaport Therapeutics Seaport Therapeutics is a clinical-stage biopharmaceutical company advancing the development of novel neuropsychiatric medicines in areas of high unmet patient needs. The Company has a proven strategy of advancing clinically validated mechanisms previously held back by limitations that are overcome with its proprietary Glyph technology platform. All the therapeutic candidates in its pipeline of first and best-in-class medicines are based on the Glyph platform, which is uniquely designed to enable oral bioavailability, bypass first-pass metabolism and reduce liver enzyme elevations or hepatotoxicity and other side effects. Seaport is led by an experienced team that invented and advanced important neuropsychiatric medicines and is guided by an extensive network of renowned scientists, clinicians, and key opinion leaders.
