A Multicentric, Randomized, Double-blind, Parallel, Placebo-controlled Phase III Study to Assess the Safety and Efficacy of Sovateltide in Patients With Acute Cerebral Ischemic Stroke.

Extensive research is being conducted in search of neuroprotective agents for possible use in the acute phase of stroke and agents that can be used for neurorepair in later stages of stroke. Several trials have been conducted and are in progress using different pharmacological agents, but none of the studies involve the stimulation of ETB receptors to treat cerebral ischemic stroke. Sovateltide (IRL-1620, PMZ-1620) has been effective in animal models of cerebral ischemic stroke. Its safety and tolerability have been demonstrated in a human phase I study with 7 subjects. Clinical phase II and III results indicate that sovateltide is a novel, first-in-class, highly effective drug candidate for treating cerebral ischemic stroke. Safety and significant efficacy in improving the National Institutes of Health Stroke Scale (NIHSS), Modified Rankin scale (mRS), and Barthel index (BI) obtained in phase II and III studies in patients with cerebral ischemic stroke in India are convincing and encouraged us to investigate its safety and efficacy in cerebral ischemic stroke patients in the United States. Therefore, the plan is to conduct a phase III clinical study to evaluate the safety and efficacy of sovateltide therapy along with standard of care in patients of acute ischemic stroke.

Sovateltide (ILR-1620) Improves Motor Function and Reduces Hyperalgesia in a Rat Model of Spinal Cord Injury

Article

作者: Karampela, Eleftheria ; Xanthos, Theodoros ; Mavridi, Artemis ; Gkiokas, George ; Iacovidou, Nicoletta ; Galanos, Antonis ; Mavridis, Theodoros

BACKGROUND:

Spinal cord injury (SCI) presents a major global health challenge, with rising incidence rates and substantial disability. Although progress has been made in understanding SCI's pathophysiology and early management, there is still a lack of effective treatments to mitigate long-term consequences. This study investigates the potential of sovateltide, a selective endothelin B receptor agonist, in improving clinical outcomes in an acute SCI rat model.

METHODS:

Thirty male Sprague-Dawley rats underwent sham surgery (group A) or SCI and treated with vehicle (group B) or sovateltide (group C). Clinical tests, including Basso, Beattie, and Bresnahan scoring, inclined plane, and allodynia testing with von Frey hair, were performed at various time points. Statistical analyses assessed treatment effects.

RESULTS:

Sovateltide administration significantly improved motor function, reducing neurological deficits and enhancing locomotor recovery compared with vehicle-treated rats, starting from day 7 post injury. Additionally, the allodynic threshold improved, suggesting antinociceptive properties. Notably, the sovateltide group demonstrated sustained recovery, and even reached preinjury performance levels, whereas the vehicle group plateaued.

CONCLUSIONS:

This study suggests that sovateltide may offer neuroprotective effects, enhancing neurogenesis and angiogenesis. Furthermore, it may possess anti-inflammatory and antinociceptive properties. Future clinical trials are needed to validate these findings, but sovateltide shows promise as a potential therapeutic strategy to improve functional outcomes in SCI. Sovateltide, an endothelin B receptor agonist, exhibits neuroprotective properties, enhancing motor recovery and ameliorating hyperalgesia in a rat SCI model. These findings could pave the way for innovative pharmacological interventions for SCI in clinical settings.

Article

作者: Raja, Anupam ; Medhi, Bikash ; Mahajan, Eshani ; K Prabha, Praisy ; Prakash, Ajay ; Jain, Ashish ; Sharma, Amit Raj

BACKGROUND:

The development of efficient therapies for Alzheimer''s disease is essential since it is a serious public health problem. This investigation sought to ascertain any potential synergistic benefits of treating Alzheimer's disease with IRL-1620 monotherapy in addition to Donepezil. Additionally, the effect of IRL-1620 was evaluated using different doses (5 μg/kg,7 μg/kg, and 9 μg/kg). The study further assessed neurobehavioral, biochemical, molecular, and histopathological parameters to evaluate the efficacy of both IRL1620 by its own and in association with Donepezil. Fifty-eight adult male Wistar rats were allocated to eight experimental groups. A dose-ranging study of IRL-1620 was conducted using different doses administered via intravenous injection. Alzheimer's disease was induced by Aβ administration, and treatment arms included disease Control (Sham), Donepezil monotherapy, and combination treatment with IRL-1620 5 μg/kg (Dose selected from the dose-ranging study). The treatment using IRL-1620 (9 μg/kg) intravenously and Donepezil (1 mg/kg orally) both on its own and in addition substantially enhanced memory in comparison with the control group (p < 0.05). Dose of IRL-1620 (9 μg/kg) intravenously, escape latency decreased and the time spent in the target quadrant was considerably increased, and they further benefited from combination therapy. Moreover, IRL-1620 (9 μg/kg) intravenously and combination treatment reduced lipid peroxidation and acetylcholinesterase levels while increasing antioxidant enzyme levels. Immunohistochemistry and molecular analysis revealed enhanced expression of neurotrophic factors with combination treatment. The combination of IRL-1620 and Donepezil showed significant improvements in memory and neurobehavioral parameters (p < 0.05). Alzheimer's disease in male Wistar rats. These results indicate to the probable therapeutic advantages of IRL-1620 and Donepezil in the management of Alzheimer's disease. The combination treatment exhibited enhanced effects compared to monotherapy, highlighting its potential promising therapeutic approach. Additional research is required to understand the mechanisms behind these synergistic benefits and to establish the ideal dosage and duration of therapy for therapeutic applications.

浅谈内皮素受体靶向药进展，适应症愈发多样化

关注并星标CPHI制药在线内皮素（ET）是一类由21个氨基酸组成的内源性多肽激素，具有强烈而持久的缩血管效应。此外，ET还参与心血管细胞的凋亡、分化和表型转化等多种病理过程，是心血管活动的重要调节因子之一。 ET包括ET-1、 ET-2和ET-3三种亚型，其中ET-1主要由血管内皮细胞合成，ET-2由肠道和肾脏产生，ET-3由神经组织释放。ET-2和ET-3与ET-1在N末端的2个和5个残基上存在差异，这决定它们在受体结合和亲和力上的差异。 ET通过作用于内皮素受体（ETR）调节人体多种重要的生理和病理过程。ETR属于典型的A类G蛋白偶联受体，包括ETA和ETB两种类型，其中ETA受体与ET-1和ET-2的结合亲、和力高于与ET-3，ETB受体与这三种异肽的结合亲和力相当。在被ET-1激活后，ETA受体和ETB受体呈现相反的血管调节作用：ETA受体激活导致长时间的血管收缩效应，而ETB受体则介导血管扩张。内皮素系统在维持血管稳态中发挥着重要作用，与多种器官系统的血管疾病密切相关，是治疗心血管系统疾病的重要靶标之一。ETR作为内皮素系统的关键组成部分，因此成为药企积极布局的热门靶点。全球已获批的ETR靶向药据不完全统计，目前全球监管机构已批准7款ETR靶向药，这些药物主要针对ETA受体，被批准用于治疗肺动脉高压。辉瑞的ETA受体拮抗剂西他生坦（sitaxentan，Thelin）也曾获监管机构批准，但因可能引起不能预测的严重肝损伤撤市。值得一提的是，近几年获批的ETR靶向药适应症与此前获批的不同，除了心脑血管疾病，还涉及肾病。具体品种来看，克拉佐生坦是Idorsia公司开发的一种强效、选择性 ETA 受体拮抗剂，2022年1月在日本被批准用于预防脑血管痉挛、血管痉挛相关的脑梗死以及动脉瘤性蛛网膜下腔出血（aSAH）术后脑缺血症状。阿普昔腾坦是一款新型口服双重ETA/ETB拮抗剂，可有效抑制ET-1与ETA和ETB的结合，从而阻断ET-1的作用。该药是马昔腾坦的活性代谢产物，具有更长的半衰期（48 h vs. 14 h），可以1天1次使用，降低血压，是第一个用于高血压治疗的ET受体拮抗剂。2024年3月，该药被FDA批准用于治疗难治性高血压，成为30多年来高血压领域获批的全新机制药物。 Sparsentan是一种每日一次的口服小分子药物，选择性靶向ETA受体和血管紧张素II 1型受体（AT1R）。2023年2月，FDA加速批准Sparsentan用于降低有快速疾病进展风险的原发性IgAN成人的蛋白尿，通常尿蛋白/肌酐比(UPCR) ≥1.5g/g。这使Sparsentan成为首个获批治疗IgAN的非免疫抑制疗法。不过Sparsentan上市后遭遇多重质疑，首先是收到了FDA肝毒性和胚胎/胎儿毒性的黑框警告，其次在跟厄贝沙坦（血管舒张素Ⅱ受体阻滞剂）的"头对头"较量中错过了III期研究的次要终点。 Sovateltide是一种高选择性ETB受体激动剂，可增加血流量，显示抗凋亡活性，保护神经线粒体，促进神经血管重塑。2023年5月，该药在日本被批准用于治疗高血压急性脑缺血性中风。ETR靶向药研究进展此外，目前全球还有多款在研ETR靶向药，详见下表。在研ETR靶向药大多作用于ETA受体。在研ETB受体靶向药整体进展较ETA受体靶向药慢，且适应症涉及肿瘤。而且，在研ETR靶向药的药物类型也比较多样，除了小分子化药，还包括单抗、抗体偶联药物（ADC）。 Atrasentan进展较快，处于3期临床。该药是Chinook开发的ETA受体拮抗剂，可选择性阻断ETA受体，通过阻断肾小球系膜细胞活化，直接的抗炎和抗纤维化，降低球囊内压力和肾小球滤过屏障大分子通透性来减少免疫球蛋白A肾病(IgAN) 患者的尿蛋白。2023年6月，诺华通过收购Chinook将Atrasentan纳入囊中。2023年10月，atrasentan治疗高危进展型IgA肾病的关键3期临床试验ALIGN取得积极中期结果：研究达到主要疗效终点，IgAN患者中的蛋白尿具有统计学意义的显著减少。研究中Atrasentan的整体安全性及耐受性良好。我国药企在ETR靶点也有布局。智康弘义的SC0062是针对慢性肾脏病的ETA受体小分子拮抗剂，其针对慢性肾脏病进行了全新的分子设计，具有独特的ETA高选择性，目标在保证疗效的同时进一步提升药物安全性。目前，SC0062正在开展针对IgA肾病和糖尿病肾脏病的2期临床研究。临床前研究表明，SC0062具有良好的活性，能够有效改善急性肾损伤和慢性肾脏病模型的病理评分。在已完成的临床I期研究中，SC0062表现出良好的安全性和耐受性及药代动力学特征，同时未发现水钠潴留等副作用，有望成为潜在的Best-in-Class药物。信立泰的SAL0120是其自主研发的小分子ETA受体拮抗剂，通过选择性拮抗ETA受体，在现有用药基础上达到进一步降低血压的目的，拟开发适应症包括轻、中度原发性高血压。鸿运华宁开发了两款ETR靶向药。其中GMA131是其自主研发的一款ETA靶向单抗。临床前及临床研究显示：GMA131具有良好的安全性，且在高脂饲料联合STZ诱导的糖尿病肾病模型中表现出了优于小分子内皮素受体拮抗剂（ERA）的疗效。2022年11月，GMA131在美国获批临床，用于治疗糖尿病肾病。 ETB靶向药较少，其中DEDN6526A是一款ADC类候选药物，由人源化 IgG1 抗 ETB单克隆抗体MEDN6000A和一种强效抗有丝分裂剂(MMAE)通过蛋白酶抑制连接体马来酰亚胺基缬氨酸-瓜氨酸-对氨基苄氧羰基 (MC-VC-PAB) 连接而成。MEDN6000A 在与其配体结合位点不同的表位上对 ETB 具有选择性和高结合亲和力。总结整体来看，ETR是个多面手，其靶向药除被批准治疗肺动脉高压、高血压等疾病，还被批准用于治疗原发性免疫球蛋白A肾病。虽然全球监管机构已批准了７款ETR靶向药，但国内外药企还在积极挖掘ETR靶向药市场，在研ETR靶向药大多作用于ETA受体，适应症也在不断扩张。尤其是ETB受体靶向药，被开发用于治疗恶性肿瘤。期待在药企的不懈努力下，ETR靶向药可以可以开启更多的可能。【企业推荐】来源：CPHI制药在线声明：本文仅代表作者观点，并不代表制药在线立场。本网站内容仅出于传递更多信息之目的。如需转载，请务必注明文章来源和作者。投稿邮箱：Kelly.Xiao@imsinoexpo.com▼更多制药资讯，请关注CPHI制药在线▼点击阅读原文，进入智药研习社~
