A Phase 2a Double-blind, Placebo-controlled, Parallel Study of PH94B Nasal Spray in the Treatment of Adjustment Disorder With Anxiety

This placebo-controlled clinical study is designed to evaluate the efficacy, safety and tolerability of administration of PH94B nasal spray four times per day as a treatment of Adjustment Disorder with Anxiety symptoms in adults. Subject participation in the Study will last a total of 6 to 10 weeks, depending on the duration of the screening period and whether they need a washout of concomitant anxiolytics. Upon signing an investigation review board approved informed consent, all subjects will complete Visit 1 (Screening) and enter a screening period lasting 7 to 35 days that could include taper of concomitant anxiolytics, if necessary. Screening visit will consist of safety assessments (medical history, physical examination, laboratory samples, electrocardiogram, urine drug screen, and urine pregnancy test [if appropriate]) and psychiatric assessments to determine eligibility. Subjects will then return to complete Visit 2 (Baseline). If the subject continues to meet inclusion and exclusion criteria, the subject will be randomized 1:1 to PH94B or placebo. Subjects will then commence 4 weeks of double-blind treatment with randomized investigational product (PH94B or placebo) four times per day.
Subjects will return for weekly site visits (Visits 3, 4, 5, and 6), in which the subject will return the vial dispensed at the previous visit and receive a new vial, except at Visit 6 in which no new vial will be dispensed. Changes in AEs and concomitant medications will be collected. During these visits, psychiatric scales will be completed. When the subject returns for Visit 6, besides the assessments completed at Visits 3 through 5, the subjects will complete a brief physical examination, electrocardiogram, laboratory tests (chemistry and blood), and urinalysis. Any remaining IP vials will be collected. The subject will then come back after a one week washout period for Follow-up visit (Visit 7).

Effect of fasedienol (PH94B) pherine nasal spray and steroidal hormones on electrogram responses and autonomic nervous system activity in healthy adult volunteers

Article

作者: Monti, Louis ; Lappalainen, Jaakko ; Hanover, Rita ; Salmán, Ester ; Smith, Mark ; Baker, Ross A.

Abstract:

Objective:

Fasedienol (PH94B) is a pherine compound formulated as a nasal spray that is hypothesized to regulate olfactory‐amygdala circuits of fear and anxiety. Fasedienol's effect on the local electrogram of nasal chemosensory neurons (EGNR) and autonomic nervous system (ANS) responses versus steroidal hormones and controls in healthy adults is reported.

Methods:

Eight males and 8 females randomly received aerosolized control (propylene glycol) and study drugs (fasedienol, 17β‐estradiol, progesterone, cortisol, and testosterone, 0.4 μg each in propylene glycol) onto the nasal septum mucosal lining at 30‐min intervals over 2 sessions. EGNR was continuously monitored; autonomic parameters were recorded before and after administration.

Results:

Fasedienol significantly increased EGNR amplitude (males: 5.0 vs. 0.6 mV, p < 0.001; females:5.7 vs. 0.6 mV, p < 0.001), and rapidly reduced respiratory rate (p < 0.05), heart rate (p < 0.01), and electrodermal activity (p < 0.05) versus control. EGNR and ANS responses after steroidal hormone administration were similar to control. 81% reported feeling less tense/more relaxed after receiving fasedienol, but not after receiving either control or steroidal hormones.

Conclusions:

Intranasal fasedienol, but not control or steroidal hormones, activated EGNR and rapidly reduced ANS responses, consistent with sympatholytic effects. Combined with subjective reports, results suggest fasedienol may provide acute relief in anxiety conditions.

A Neuroanatomic and Pathophysiologic Framework for Novel Pharmacological Approaches to the Treatment of Post-traumatic Stress Disorder

Review

作者: Norred, Michael A ; Hamner, Mark B ; Zuschlag, Zachary D

Post-traumatic stress disorder (PTSD) is a debilitating disorder inflicting high degrees of symptomatic and socioeconomic burdens. The development of PTSD results from a cascade of events with contributions from multiple processes and the underlying pathophysiology is complex, involving neurotransmitters, neurocircuitry, and neuroanatomical pathways. Presently, only two medications are US FDA-approved for the treatment of PTSD, both selective serotonin reuptake inhibitors (SSRIs). However, the complex underlying pathophysiology suggests a number of alternative pathways and mechanisms that may be targets for potential drug development. Indeed, investigations and drug development are proceeding in a number of these alternative, non-serotonergic pathways in an effort to improve the management of PTSD. In this manuscript, the authors introduce novel and emerging treatments for PTSD, including drugs in various stages of development and clinical testing (BI 1358894, BNC-210, PRAX-114, JZP-150, LU AG06466, NYV-783, PH-94B, SRX246, TNX-102), established agents and known compounds being investigated for their utility in PTSD (brexpiprazole, cannabidiol, doxasoin, ganaxolone, intranasal neuropeptide Y, intranasal oxytocin, tianeptine oxalate, verucerfont), and emerging psychedelic interventions (ketamine, MDMA-assisted psychotherapy, psilocybin-assisted psychotherapy), with an aim to examine and integrate these agents into the underlying pathophysiological frameworks of trauma-related disorders.

Medial Patellofemoral Ligament Reconstruction Using Adductor-Transfer and Adductor-Sling at Nonanatomic Femoral Attachment Sites Leads to Unfavorable Graft-Length Change Patterns: A Descriptive Biomechanical Study

1区 · 医学

Article

作者: Dong, Shikui ; Chen, Jiebo ; Xu, Junjie ; Zhao, Jinzhong ; Qiao, Yi ; Ye, Zipeng ; Han, Kang ; Xu, Caiqi

PURPOSE:

To compare the graft length change patterns in nonanatomic adductor-transfer (AT) and adductor-sling (AS) medial patellofemoral ligament (MPFL) reconstruction with those in anatomic MPFL reconstruction (MPFLR) and to investigate the favorable isometric ranges (FIRs) of knee flexion.

METHODS:

Eight small fresh-frozen cadaveric knees were mounted in a knee-customized jig with tensioned muscles to measure graft length changes from two patellar points to four femoral attachments using a linear variable displacement transducer. Femoral attachments were at the MPFL footprint center (MPFL-C) in anatomic MPFLR, adductor magnus (AM) footprint center (AM-C) in AT, and at 5-mm (AM-5) or 10-mm (AM-10) points proximal to AM-C in AS. The FIRs of these femoral attachments were determined after zeroing the graft length changes at different initial fixation angles.

RESULTS:

Anatomic MPFL-C resulted in almost isometric graft length changes from 0° to 90°. At AM-C, the graft length changes displayed an increase from 0° to 45° and significantly greater length changes than those at MPFL-C from 60° to 90°. The graft length changes at both AM-5 and at AM-10 continuously increased with knee flexion angles and presented significantly larger graft length changes than those at MPFL-C and at AM-C from 30° to 90° and 60° to 90°, respectively. After zeroing graft length changes at different fixation angles, the FIRs of the MPFL-C covered all knee flexion angles, regardless of the patellar attachments and initial fixation angles. Moreover, with the smaller FIRs of AM-C observed at any fixation angle when compared with MPFL-C, fixing the graft at 0° to 30° in AT allowed the FIRs to cover the whole functional flexion range. However, the significantly larger graft length changes of both AM-5 and AM-10 resulted in extremely limited FIRs at any fixation angle.

CONCLUSION:

Anatomic MPFL-C resulted in a favorable graft length change range (less than 2 mm) at 0° to 90° of knee flexion, which was close to the isometric graft behavior. However, nonanatomic attachments of AM-C in AT, and both AM-5 and AM-10 in AS caused significant anisometric graft length change patterns and limited FIRs. Moreover, AT had a smaller range of graft length change but wider FIRs compared to AS, indicating superior graft behavior for MPFLR.

CLINICAL RELEVANCE:

Anatomic MPFLR is preferable for the treatment of in skeletally immature patients, followed in preference by nonanatomic AT. Nonanatomic AS should be performed cautiously.

Vistagen Initiates Fasedienol Repeat Dose Study for the Acute Treatment of Social Anxiety Disorder

SOUTH SAN FRANCISCO, Calif.--( BUSINESS WIRE )--Vistagen (Nasdaq: VTGN), a late clinical-stage company dedicated to pioneering neuroscience based on nose-to-brain neurocircuitry, today announced enrollment of the first subject in a repeat dose study of fasedienol, its investigational neuroactive pherine nasal spray in Phase 3 development for the acute treatment of social anxiety disorder (SAD). The repeat dose study is a small exploratory U.S. Phase 2 multi-center, randomized, double-blind, placebo-controlled, three-arm clinical trial designed to assess the efficacy, safety, and tolerability of a repeat dose of fasedienol (3.2 micrograms) in adults with SAD during a public speaking challenge conducted in a clinical setting. The three dosing arms will be fasedienol followed by fasedienol (total 6.4 micrograms), fasedienol followed by placebo (total 3.2 micrograms), and placebo followed by placebo, with the second dose in each arm administered ten minutes after the initial dose. Other than the repeat dose and the additional study arm, the study is similar in design to the ongoing PALISADE Phase 3 studies for the acute treatment of adults with SAD, including an open-label extension. "The initiation of this fasedienol repeat dose study marks another significant milestone in our U.S. Phase 3 program for the acute treatment of social anxiety disorder,” said Shawn Singh, President and Chief Executive Officer of Vistagen. “With the increasing prevalence of social anxiety disorder over decades, millions of individuals in the U.S. live with debilitating acute fear and anxiety in everyday social situations without any U.S. FDA-approved acute treatment option. Our mission and PALISADE Phase 3 program for fasedienol are focused on changing that." About Vistagen’s U.S. Registration-directed PALISADE Phase 3 Program for Fasedienol for the Acute Treatment of Social Anxiety Disorder Complementing its statistically significant PALISADE-2 U.S. Phase 3 trial of fasedienol for the acute treatment of adults with SAD reported in 2023, Vistagen's U.S. registration-directed PALISADE Phase 3 program for fasedienol for the acute treatment of SAD includes its ongoing PALISADE-3 and PALISADE-4 U.S. Phase 3 trials and a small U.S. Phase 2 repeat dose study. PALISADE-3 and PALISADE-4 are each a multi-center randomized, double-blind, placebo-controlled Phase 3 trial designed similarly to PALISADE-2 to evaluate the efficacy, safety, and tolerability of the acute administration of fasedienol to relieve anxiety symptoms in subjects with SAD induced by a public speaking challenge conducted in a clinical setting. Vistagen believes either PALISADE-3 or PALISADE-4, if successful, together with PALISADE-2, may establish substantial evidence of the effectiveness of fasedienol in support of a potential fasedienol New Drug Application (NDA) submission to the U.S. FDA for the acute treatment of SAD. About Fasedienol Nasal Spray for the Acute Treatment of Social Anxiety Disorder Fasedienol is a potential first-in-class, investigational neurocircuitry-focused pherine nasal spray designed to have rapid onset with a novel mechanism of action (MOA) that is differentiated from all currently approved anxiety medications. Fasedienol is designed to regulate the olfactory-amygdala neural circuits of fear and anxiety and attenuate the tone of the sympathetic autonomic nervous system without systemic absorption, potentiation of GABA-A receptors, or binding to neurons in the brain. Vistagen’s U.S. registration-directed PALISADE Phase 3 program for fasedienol is focused on the acute treatment of SAD. There is no U.S. FDA-approved acute treatment for SAD, and the U.S. FDA has granted Fast Track designation for the development of fasedienol for the acute treatment of SAD. About Vistagen Headquartered in South San Francisco, CA, Vistagen (Nasdaq: VTGN) is a late clinical-stage company leveraging its pioneering neuroscience and deep understanding of nose-to-brain neurocircuitry to develop and commercialize a broad and diverse pipeline of a new class of intranasal product candidates called pherines. Each pherine product candidate in Vistagen’s neuroscience pipeline is designed to rapidly activate brain neurocircuitry through the olfactory system to achieve desired therapeutic benefits. Pherines do not require systemic absorption or binding to neurons in the brain, which may contribute to a favorable safety profile. Vistagen’s neuroscience pipeline also includes an oral prodrug, AV-101, with potential to impact certain neurological conditions involving the NMDA receptor. Vistagen is passionate about developing transformative treatment options to improve the lives of individuals underserved by the current standard of care for multiple highly prevalent disorders, including social anxiety disorder, major depressive disorder, and vasomotor symptoms (hot flashes) associated with menopause.

2025年值得关注的10项临床研究，针对社恐、暴食症、夜盲症……

GLP-1、ADC、双抗……是2024年创新药行业的高频词汇，相关交易层出不穷，以上热门靶点和创新技术为多个疾病领域带来了治疗突破，填补了诸多临床未满足需求。创新药的故事持续演绎，不断有创新疗法经过临床研究的验证走向成功。去年末，医药魔方从疾病负担和靶点角度筛选了8项值得关注的研究，其中有6项在2024年揭晓结果，喜悲参半。当下，基于医药魔方TrialCube数据库，我们从843项预计在2025年完成的III期临床试验中筛选出特别值得关注的10项研究，供大家参考。 2025年值得期待的10项III期研究注：医药魔方整理 NO.1 顽固的高血压有望迎来创新疗法在β受体阻滞剂、血管紧张素转换酶抑制剂（ACEI）、血管紧张素II受体抑制剂（ARB）等多种类型降压药物出现后，高血压患者的降压需求得到了极大的满足。但是，仍然有一半的患者无法实现较好的血压控制效果。大约25%的高血压源于醛固酮水平失调。醛固酮水平受肾素-血管紧张素-醛固酮系统（RAAS）调控，因而阻断RAAS是大部分现有降压药物的主要机制，例如阿利吉仑（肾素抑制剂，抑制血管紧张素原转化为血管紧张素I）、卡托普利（ACEI，抑制血管紧张素I转化为血管紧张素II）、缬沙坦（ARB，阻断血管紧张素II与其受体的结合）等。不过，目前还没有针对性抑制醛固酮（aldosterone）合成的药物上市。醛固酮合成酶（ALDOS，由CYP11B2基因编码）是一个较为新颖的研究方向，其关键之处在于可调控醛固酮合成的最后3个步骤，因而是抑制醛固酮合成的理想靶点。不过，由于CYP11B2基因与编码皮质醇合成酶的CYP11B1基因的序列同源性较高（93%），药物选择性差会导致患者的皮质醇水平也受到影响，因而控制选择性是开发ALDOS抑制剂必须解决的一个大难题。已上市的奥西卓司他（Novartis/Recordati）便是一款未能分离CYP11B1与CYP11B2选择性的产品，因而其仅获批了库欣综合征适应症。目前，全球已有2款针对高血压的ALDOS抑制剂进入III期阶段，即Baxdrostat（阿斯利康）和Lorundrostat（Mineralys Therapeutics）。临床前数据显示，Baxdrostat和Lorundrostat的CYP11B2/CYP11B1选择性分别为>100倍和374倍。这两款药物均已有II期研究数据披露。 Baxdrostat和Lorundrostat的II期研究降压数据从II期研究数据来看，Baxdrostat和Lorundrostat的降压效果差距不大，而且研究中均未出现皮质醇水平异常的情况。这两款药物的降压III期研究预计均将在2025年完成，届时可进一步知晓其抗高血压潜力。按登记数据来看，Lorundrostat将比Baxdrostat早7个月完成，我们可以先期待一下Lorundrostat的数据。 NO.2 丰富胶质母细胞瘤治疗选择大多数肿瘤类型已经拥有多样化的治疗选择，但胶质母细胞瘤（GBM）是其中的例外。GBM是最常见也是最具侵袭性的一种脑肿瘤，被称为“脑瘤之王”，约占原发性恶性中枢神经系统肿瘤的46.1%。手术和放化疗是这类患者的传统治疗策略，但预后不佳。恶性胶质瘤患者5年总生存率不足10%。目前，GBM的靶向治疗药物仅包括贝伐珠单抗和伯瑞替尼，其中后者仅限于PTPRZ1-MET融合基因的IDH突变型星形细胞瘤（WHO 4级）或有低级别病史的胶质母细胞瘤患者使用。除此之外，Novocure和再鼎医药合作开发的肿瘤电场疗法TTFields也可用于治疗GBM。研究表明，脂肪酸合成酶（FASN）是调节脂质代谢的最重要的蛋白质之一。许多实体瘤和血液肿瘤都过度表达FASN，包括复发性GBM等。地尼法司他（ASC40）是歌礼制药自Sagimet Biosciences引进的一款脂肪酸合成酶（FASN）抑制剂，可抑制肿瘤细胞能量供应和扰乱肿瘤细胞膜磷脂组成。 II期临床数据显示，GBM患者接受地尼法司他联合贝伐珠单抗治疗后，客观缓解率（ORR）达到了65%，其中完全缓解（CR）和部分缓解（PR）分别占17%和39%。此外，无进展生存期（PFS）达到6个月的患者比例为47%，明显高于过往贝伐珠单抗单药治疗的6个月PFS历史数据（16%）。歌礼制药针对GBM开展的III期ASC40-301研究将于2025年6月完成。该研究若能获得积极结果，地尼法司他有望成为GBM患者的突破性治疗药物。 NO.3 社恐人群的第二个希望社恐是一种严重的焦虑症，其特征是对社交或与表现相关的情况持续、强烈的恐惧。美国大约有2370万成人社恐患者，我国每年大约有560万人确诊社恐。目前尚无速效、按需治疗社恐的疗法获批。当前的护理标准为抗抑郁药和苯二氮卓类药物的超说明书使用，其具有显著的潜在副作用和安全性问题。此前鼻喷雾剂PH94B（fasedienol）曾在III期研究中展现出对社恐有疗效的迹象，但其疗效仍然存疑，并且临床设计也有不合理的地方，因此PH94B仍在反反复复验证其社恐治疗效果。 BNC210是Bionomics开发的一款靶向α7烟碱乙酰胆碱受体（α7 nAChR）的负向变构调节剂，已获FDA授予快速通道资格，用于治疗创伤后应激障碍（PTSD）、其他创伤和压力源相关疾病、急性治疗社恐和其他焦虑相关疾病。 2023年3月，BNC210（225mg或675mg）治疗社恐的II期PREVAIL研究顺利完成。数据显示，相比于安慰剂组，BNC210组患者的主观焦虑量表（SUDS）评分未显著改善（评分差异为5.69分，P=0.165），但结果具有临床意义且显示出了BNC210有益于改善社恐患者焦虑症状的趋势。因而，Bionomics还是决定在III期研究（AFFIRM-1）中继续评估BNC210的社恐治疗潜力。这项III期研究将在2025年8月完成。社恐人群能否拥有缓解社交焦虑症状的药物，相信明年可以知晓答案。 NO.4 “万能”GLP-1的下一个惊喜 GLP-1从2023年火到了2024年，这不仅仅是因为GLP-1药物具备强大的降糖和减肥效果，还因为其出色的“破圈”能力。迄今为止，以司美格鲁肽和替尔泊肽为代表的GLP-1药物已经在阻塞性睡眠呼吸暂停（OSA）、代谢障碍相关脂肪性肝炎（MASH）、慢性肾病（CKD）等疾病领域展现了其“溢出效应”。阿尔茨海默病将是GLP-1“破圈”计划的下一站。已经有不少文献揭示过GLP-1对阿尔茨海默病的有益治疗作用。近期，还有一项基于美国电子健康记录的模拟研究表明，接受司美格鲁肽（Ozempic）治疗的2型糖尿病患者，首次确诊阿尔茨海默病的风险降低了67%。这为诺和诺德开展的司美格鲁肽治疗阿尔茨海默病的III期研究提供了更高的成功确定性。 NO.5 强效降脂靶点有望迎来首个口服药物 Enlicitide（MK-0616）是默沙东开发的一款口服环肽类前蛋白转化酶枯草溶菌素9（PCSK9）抑制剂。PCSK9主要在肝脏表达，是“坏胆固醇”LDL-C升高的帮凶。PCSK9可与肝细胞表面负责清除LDL-C的受体结合，导致LDL-C堆积。针对高胆固醇血症的IIb期研究（n=381）结果显示，治疗第8周，接受Enlicitide（6/12/18/30mg，每日1次）治疗的患者的LDL-C水平均实现了统计学意义的降低，具体降幅分别为-41.2%、-55.7%、-59.1%和-60.9%。目前，全球共6款PCSK9靶向药物获批上市，分别为英克司兰（诺华）、托莱西单抗（信达生物）、依洛尤单抗（安进/安斯泰来）、阿利西尤单抗（再生元/赛诺菲）、伊努西单抗（康方生物）和昂戈瑞西单抗（君实生物），这6款产品均已在中国上市。此外，还有恒瑞医药的瑞卡西单抗和Lib Therapeutics/海森生物的莱达西贝普处于申请上市阶段。 PCSK9赛道的白热化竞争足以说明该靶点在降脂上的市场潜力。作为目前进展最快的口服PCSK9药物，Enlicitide的III期研究能否取得足够显著的疗效数据，值得期待。 NO.6 鼻喷疫苗扩圈至RSV领域虽然RSV赛道在今年遇到了不小的挫折，但是RSV疫苗的前景仍然值得期待，毕竟消除这个威胁婴幼儿和老年人生命的呼吸道疾病仍然是全球国家的共同目标。赛诺菲此前布局的RSV中和抗体Beyfortus（尼塞韦单抗）已经上市，可保护新生儿在第一个RSV流行季（当年10月-次年3月）不受感染。不过，该产品面临来自辉瑞、GSK和Moderna的RSV疫苗的激烈竞争。 RSVt疫苗（SP0125）是赛诺菲与美国国家过敏和传染病研究所（NIAID）合作开发的一款针对RSV感染的鼻喷减毒活疫苗，适用于全年龄段幼儿。可以说，RSVt疫苗是赛诺菲在RSV赛道选择的差异化策略。公开资料显示，RSVt疫苗可以在保护新生儿在第二个RSV流行季（次年4月-次年9月）不受感染。因此，Beyfortus和RSVt疫苗提供的双防线保障可以更大程度降低新生儿发生RSV感染的机率。若是能顺利完成III期研究，赛诺菲预计最早将在2026年提交该疫苗的上市申请。 NO.7 椎间盘退行性疾病的手术“救星” 椎间盘退行性疾病是一种常见的脊柱问题，主要影响中老年人群以及长期久坐人群。据估计，至少30%的30-50岁人群和大约90%的50岁以上人群会出现椎间盘退行。腰痛是这类疾病最常见的症状，其它症状还包括下肢疼痛麻木、间歇性跛行等。症状轻的患者可以通过物理治疗或者锻炼缓解症状，但是症状严重者需要手术治疗。椎体间融合术是目前治疗腰椎退行性疾病经典而有效的手术方法，其目的是通过将不稳定椎体进行融合消除因脊柱结构完整性丢失所致的脊柱病理性运动，以缓解疼痛、提高功能活动能力并改善生存质量。但据文献报道，腰椎融合术后不融合发生率可高达56%。长期未融合的腰椎假关节会带来诸多问题。因而，提高脊柱融合率是一个亟待解决的问题。 AGA111是安济盛开发的一款重组人骨形态发生蛋白6（BMP-6），与体内BMP主要拮抗剂Noggin的结合具有可逆性，低剂量下即可在体内实现良好的成骨效果。此外，AGA111采用了无免疫原性、无致炎性的内源性生物相容性材料——自体血凝块作为递送载体，可以有效减少局部水肿和炎性反应的风险。 II期研究结果显示，在椎体间融合术后12个月时，AGA111（0.25/0.5mg）组受试者的新骨形成比例中位数高于对照组（安慰剂+自体血凝块），疼痛评分较基线改善幅度也明显优于对照组。此外，AGA111在研究中还显示出了在促进脊柱融合、改善功能障碍等方面的初步临床疗效。 NO.8 夜盲症治疗的曙光夜盲症是指在光线昏暗环境下或夜晚视物不清或完全看不见东西的症状，其致病原因多种多样，例如缺乏维生素A、视网膜病变、遗传因素、屈光手术影响等。据统计，美国约有3800万例夜盲症患者，我国约有1500万例夜盲症患者。因维生素A缺乏引起的暂时性夜盲可以通过服用维生素A补充剂或摄入富含维生素A的食物来缓解症状，但因视网膜病变和遗传因素等原因导致的夜盲症还没有可用的治疗药物。 Nyxol（0.75%甲磺酸酚妥拉明滴眼液）是目前唯一一款处于III期阶段的在研夜盲症治疗药物，可通过阻断虹膜扩张肌上的α1肾上腺素能受体（α1-AR）和α2肾上腺素能受体（α2-AR）起到适度缩瞳作用（昏暗环境下瞳孔会放大），从而改善患者在昏暗环境下的视觉功能。 Nyxol已在2022年顺利完成了一项针对夜盲症的III期研究（LYNX-1）。结果显示，治疗第8天，Nyxol组达到中间视觉低对比度视力（mLCVA）改善10个及以上字母的患者比例更高（41% vs 22%，P<0.05），达到mLCVA改善15个及以上字母的患者比例也更高（13% vs 3%，P<0.05）。为了进一步验证Nyxol在夜盲症上的疗效和安全性，Opus Genetics（已被Ocuphire Pharma收购）开展了第2项III期研究（LYNX-2）。Opus Genetics预计在2025年第一季度便可以获得这项研究的顶线结果。 NO.9 暴食症治疗手段有望革新暴食症会导致胃肠道疾病、高血压、肥胖及由此引起的代谢和各系统功能紊乱等躯体问题，危害患者的身心健康。大约3.5%的女性和2%的男性存在暴食性障碍，超重或肥胖人群更为常见。目前，临床上的暴食症治疗手段包括心理治疗和药物治疗。药物治疗以抗抑郁药和食欲抑制药物为主，但真正获批可用于治疗暴食症的药物只有利右苯丙胺，而利右苯丙胺存在成瘾性风险。索安非托是一款多巴胺重摄取抑制剂和去甲肾上腺素重摄取抑制剂，已在2019年3月获FDA批准上市，用于治疗嗜睡。今年4月，Axsome Therapeutics宣布启动治疗暴食症的III期ENGAGE研究，在此之前其并未披露过相关临床数据。该药物是目前唯一一款正在III期研究中验证暴食症治疗潜力的药物。 NO.10 卵巢癌治疗选择有待丰富卵巢癌是治疗突破较少的常见肿瘤之一。目前，卵巢癌的标准治疗仍然是化疗。然而大多数患者会对化疗产生耐药性。耐药后卵巢癌的治疗药物仅包括PARP抑制剂、贝伐珠单抗和索米妥昔单抗，而PARP抑制剂和索米妥昔单抗的使用受限于生物标志物水平。化疗仍是卵巢癌的治疗方案中的重要一环，因而着力解决化疗耐药问题是药物研发方向之一。研究表明，化疗耐药的驱动因素之一可能是糖皮质激素，糖皮质激素过度激活其受体后会导致化疗对肿瘤细胞的杀伤能力下降。 Relacorilant是Corcept Therapeutics基于此机制开发的一款糖皮质激素受体拮抗剂，能够通过竞争性拮抗糖皮质激素的抗凋亡作用来恢复化疗敏感性并提高化疗效果。 Relacorilant的作用机制针对卵巢癌的II期研究结果显示，相比于白蛋白紫杉醇组，Relacorilant联合白蛋白紫杉醇组患者的无进展生存期显著延长（5.6 vs 3.8个月，HR=0.66，P=0.038），总生存期有所延长（HR=0.67，P=0.066）。推荐阅读 2025年，这20款重磅新药有望在中国获批 2024年医药并购交易：肿瘤降温，自免热潮 2025年全球畅销药TOP10预测，GLP-1产品占4款，Skyrizi飞升 2024年值得关注的8项临床研究：强迫症、万能GLP-1、首个口服Aβ靶向药…… Copyright © 2024

Vistagen Reports Fiscal Year 2025 Second Quarter Financial Results and Corporate Update

SOUTH SAN FRANCISCO, Calif.--( BUSINESS WIRE )-- Vistagen (Nasdaq: VTGN), a late clinical-stage company dedicated to pioneering neuroscience based on nose-to-brain neurocircuitry, today reported financial results for its fiscal year 2025 second quarter ended September 30, 2024, and provided a corporate update. “We initiated our PALISADE-4 Phase 3 trial during our second quarter, achieving yet another significant milestone in our fasedienol U.S. registration-directed Phase 3 Program for the acute treatment of social anxiety disorder,” said Shawn Singh, Chief Executive Officer of Vistagen. “We are actively recruiting for both our PALISADE-3 and PALISADE-4 Phase 3 trials and remain primarily focused on execution. Our broad and diverse neuroscience pipeline is based on our novel, non-systemic, neurocircuitry-focused approaches to treating multiple challenging disorders in high-prevalence markets with inadequate current treatment options. As we head into 2025, we expect data from multiple Phase 3 clinical trials in social anxiety disorder and further advancement of our non-systemic pherine product candidates in Phase 2 programs for treatment of major depressive disorder and hormone-free treatment of menopausal hot flashes, each with potential to set a new standard of care.” Neuroscience Pipeline Highlights Leveraging its pioneering neuroscience and deep understanding of nose-to-brain neurocircuitry, Vistagen is advancing a broad and diverse pipeline of innovative non-systemic intranasal pherine product candidates. Fasedienol for the Acute Treatment of Social Anxiety Disorder (SAD) During the second quarter, Vistagen announced initiation of its PALISADE-4 Phase 3 trial of fasedienol for the acute treatment of SAD. Vistagen’s PALISADE-3 and PALISADE-4 Phase 3 trials remain on track to produce top-line results in 2025. Itruvone for Major Depressive Disorder (MDD) Vistagen continues preparations and planning for Phase 2B development of itruvone as a novel, non-systemic, stand-alone treatment for MDD without the weight gain, sexual side effects, and safety concerns associated with currently available depression therapies. PH80 for Vasomotor Symptoms (Hot Flashes) due to Menopause Vistagen’s ongoing U.S. Investigational New Drug Application (IND)-enabling program for PH80 is designed to support its planned submission of a U.S. IND to facilitate further Phase 2 clinical development of PH80 in the U.S. as a novel non-systemic, hormone-free treatment option for millions of women affected by vasomotor symptoms (hot flashes) due to menopause. Corporate Highlight Raising Awareness at Nasdaq on World Mental Health Day Vistagen partnered with The Goldie Hawn Foundation’s MindUP to raise awareness of global mental health challenges and the power of partnership and shared commitment to advance neuroscience-based innovation in a Nasdaq Closing Bell ceremony in New York City on World Mental Health Day. Financial Results for Fiscal Year 2025 Second Quarter Ended September 30, 2024 Research and development (R&D) expense R&D expense was $10.2 million for the three months ended September 30, 2024, as compared to $3.9 million for the three months ended September 30, 2023. The increase in R&D expense was primarily due to an increase in research, development, and contract manufacturing expenses related to our PALISADE Phase 3 Program for fasedienol in SAD, an increase in headcount, and an increase in consulting and professional service fees. General and administrative (G&A) expense G&A expense was $4.2 million for the three months ended September 30, 2024, as compared to $3.2 million for the three months ended September 30, 2023. The increase in G&A expense was primarily due to an increase in headcount and professional service fees. Net loss Net loss was $13.0 million for the three months ended September 30, 2024, as compared to $6.6 million for the three months ended September 30, 2023. Other financial highlights Cash, cash equivalents, and marketable securities were $97.6 million as of September 30, 2024.

About Fasedienol Nasal Spray for Acute Treatment of Social Anxiety Disorder Fasedienol is a potential first-in-class, investigational neuroactive pherine nasal spray designed to have rapid onset with a novel mechanism of action (MOA) that is differentiated from all currently approved anxiety medications. Fasedienol is designed to regulate the olfactory-amygdala neural circuits of fear and anxiety and attenuate the tone of the sympathetic autonomic nervous system, without systemic absorption, potentiation of GABA-A receptors, or binding to neurons in the brain. Vistagen’s U.S. registration-directed PALISADE Phase 3 program for fasedienol is focused on the acute treatment of SAD. Fasedienol has not demonstrated any signals of abuse potential or suggested any potential for psychological and physical dependence in any clinical trial conducted to date. There is no U.S. FDA-approved acute treatment for SAD. The U.S. FDA has granted Fast Track designation for the development of fasedienol for the acute treatment of SAD. About Itruvone Nasal Spray for Major Depressive Disorder Itruvone is an investigational pherine nasal spray designed to have rapid onset, with a novel proposed neurocircuitry-focused mechanism of action (MOA) that is fundamentally differentiated from the MOA of all currently approved treatments for depression disorders. Itruvone is administered intranasally at microgram-level doses and is designed to regulate olfactory-to-amygdala neural circuitry believed to increase the activity of the limbic-hypothalamic sympathetic nervous system and increase the release of catecholamines to produce antidepressant effects, without systemic absorption or brain penetration and without many of the side effects and safety concerns potentially associated with currently approved antidepressants. Vistagen is developing itruvone as a potential new non-systemic, stand-alone treatment for major depressive disorder, and the FDA has granted Fast Track designation for the development of itruvone for that indication. About PH80 Nasal Spray for Vasomotor Symptoms (Hot Flashes) Due to Menopause PH80 is a hormone-free investigational neuroactive pherine nasal spray with a novel neurocircuitry-focused mechanism of action (MOA) that is fundamentally differentiated from all currently approved treatment options for women’s health indications. PH80’s proposed MOA does not require systemic absorption or binding to neurons in the brain. Vistagen is developing PH80 as a potential new non-systemic, hormone-free treatment for the management of vasomotor symptoms (hot flashes) due to menopause. About Vistagen Headquartered in South San Francisco, CA, Vistagen (Nasdaq: VTGN) is a late clinical-stage company leveraging its pioneering neuroscience and deep understanding of nose-to-brain neurocircuitry to develop and commercialize a broad and diverse pipeline of intranasal product candidates called pherines. Each pherine product candidate in Vistagen’s neuroscience pipeline is designed to rapidly activate olfactory system and brain neurocircuitry to achieve desired therapeutic benefits and differentiated safety without requiring systemic absorption or binding to neurons in the brain. Vistagen’s neuroscience pipeline also includes an oral prodrug, AV-101, with potential to impact certain neurological conditions involving the NMDA receptor. Vistagen is passionate about developing transformative treatment options to improve the lives of individuals underserved by the current standard of care for multiple highly prevalent disorders, including social anxiety disorder, major depressive disorder, and vasomotor symptoms (hot flashes) associated with menopause.
