According to the National Instituye of Arthritis and Musculoskeletal and Skin Diseases, psoriasis is a chronic, long-lasting disease in which the immune system becomes overactive, causing skin cells to multiply too quickly. Patches of skin become scaly and inflamed, most often on the scalp, elbows, or knees, but other parts of the body can be affected as well. It is thought the disease currently affects 125 million people globally, with an estimated 7.5 million adults in the US impacted by the condition. “We are excited about AX-158’s potential as the first immunomodulator in the Nck blocker class. Our pre-clinical data supports the potential for AX-158 to realize effective outcomes without the immunosuppression and the side effects associated with existing autoimmune disease therapies, said Artax CEO Rob Armstrong. Immunomodulation assists the immune system in maintaining healthy control, addressing the underlying driver of autoimmune diseases. As the first in a new class of Nck blockers, AX-158 has the potential to establish a new standard of care in autoimmune disease treatment, Artax said. By selectively targeting Nck function, which plays a critical role in immune system function, AX-158 recalibrates the body’s T-cell receptor (TCR) responses. According to the company, AX-158 has ‘broad potential’ to treat many autoimmune diseases without causing immunosuppression – as the therapy allows the immune system to only activate when it recognizes a true disease threat. googletag.cmd.push(function () { googletag.display('text-ad1'); }); “The new Nck blocker class of agents, AX-158, has the potential to change how we treat autoimmune disease through targeting and tempering TCR responses so the body only, and properly, reacts against strong pathogens,” commented James Krueger, head of the laboratory for investigative dermatology at The Rockefeller University and Artax board member. “I am excited to see how this new mechanism of action translates into biomarker changes and patient responses, where to date only targeted immunosuppression has been applied.” The company said it is ‘eager’ to see positive validation for AX-158 when the trial results are available later this year. The symptoms can sometimes go through cycles, flaring for a few weeks or months followed by periods when they subside or go into remission. Mild psoriasis can often be successfully treated with creams or ointments, while moderate and severe psoriasis may currently require pills, injections, or light treatments. Managing common triggers, such as stress and skin injuries, can also help keep the symptoms under control.

Safety and Efficacy Results Are Expected in Second Half of 2024 Evaluating AX-158, a First in Class Nck Blocker, Shifting the Paradigm of Autoimmune Disease Treatment AX-158 Has Broad Potential to Treat Many Autoimmune Diseases without Causing Immunosuppression Autoimmune Diseases Remain a Significant Unmet Medical Need, Affecting Millions of Patients Globally CAMBRIDGE, Mass., Feb. 13, 2024 /PRNewswire/ -- Artax Biopharma, Inc., a clinical-stage biotechnology company focused on transforming the treatment of autoimmune diseases, today announces that the first patient has been dosed in the Company's Phase 2a trial evaluating the safety and biomarker responses of AX-158 in a first proof of mechanism trial in psoriasis. The Company expects these results to be available in the second half of this year. "We are excited about AX-158's potential as the first immunomodulator in the Nck blocker class. Our pre-clinical data supports the potential for AX-158 to realize effective outcomes without the immunosuppression and the side effects associated with existing autoimmune disease therapies," stated Artax Chief Executive Officer, Rob Armstrong, Ph.D. "We are eager to see this validation when the results from this psoriasis Phase 2a trial are available later this year." Immunomodulation assists the immune system in maintaining healthy control, addressing the underlying driver of autoimmune diseases. As the first in a new class of Nck blockers, AX-158 has the potential to establish a new standard of care in autoimmune disease treatment. By selectively targeting Nck function, which plays a critical role in immune system function, AX-158 recalibrates the body's T-cell receptor (TCR) responses. This recalibration to responses allows the immune system to continue functioning properly and activate only when it recognizes true disease threats – preventing self-activation without causing immune suppression that makes the body susceptible to numerous infections. "The new Nck blocker class of agents, AX-158, has the potential to change how we treat autoimmune disease through targeting and tempering TCR responses so the body only, and properly, reacts against strong pathogens," commented James G. Krueger, M.D., Ph.D., Head of the Laboratory for Investigative Dermatology at The Rockefeller University and Artax Scientific Advisory Board member. "I am excited to see how this new mechanism of action translates into biomarker changes and patient responses, where to date only targeted immunosuppression has been applied." About Autoimmune Disease and Psoriasis Psoriasis is a common, immune-mediated disease that affects 125 million people globally. In the US 3.0% of the adult population, or more than 7.5 million adults, are affected. Psoriasis patients may exhibit visible signs of inflammation anywhere on the body as raised plaques and scales on the skin. Plaques may appear as few small patches or can affect large areas. It is possible to have psoriasis plaques and scales on more than one location on the body at a time. Treating psoriasis can help improve symptoms as well as lower the risk of developing other health conditions such as psoriatic arthritis, heart disease, obesity, diabetes, and depression. About Artax Biopharma Artax Biopharma is a clinical-stage biotechnology company transforming the treatment of T Cell-driven autoimmune diseases. Artax's first-in-class oral small molecules aim to deliver immune system modulation without immunosuppression, potentially unlocking new treatment options as both monotherapy and in combination with other treatments. The lead program AX-158 will deliver Phase 2a Proof of Concept data in psoriasis later in 2024. We believe there is significant potential for its approach to revolutionize treatment of T Cell-driven diseases. Immunomodulation maintains healthy control of the immune system and addresses the underlying source of T Cell-driven diseases. Central to a well-functioning immune system is the T Cell Receptor (TCR). When TCR signaling becomes dysregulated, it causes T Cell-driven conditions, including autoimmune diseases, and induced T Cell pathologies where medical treatments result in immune reactions (such as stem cell transplants resulting in acute graft-versus-host-disease or immuno-oncology treatments resulting in immune related-adverse events). We believe the immunomodulation mechanism offered by our investigational agents holds broad potential to revolutionize how these T Cell-driven autoimmune diseases are addressed, while not impairing the ability of a patient's immune system to function properly. Artax Biopharma is based in the Boston area and raised Series A & B from Advent Life Sciences, Sound Bioventures, and Columbus Venture Partners. For more info, see or follow us on LinkedIn.

mg）中接受治疗的9名可评估的患者中有8名达到SD的最佳反应，DCR为89%。SY-5609：公布1/1b期临床试验数据Syros Pharmaceuticals公司公布了其新型可口服的CDK7抑制剂SY-5609在晚期实体瘤中的早期临床试验数据。公开资料显示，SY-5609对CDK7具有更高的选择性和效力，因而成为Syros Pharmaceuticals公司优先开发的对象。此次公布的数据显示，SY-5609作为单一药物（10 mg，为单用的最大耐受剂量）和联合用药（4或5 mg加吉西他滨）时，观察到了令人鼓舞的临床活性。在三名具有特定实体瘤的可评估患者（包括一名胰腺导管腺癌患者）中，SY-5609单药治疗（10 mg）的疾病控制率（DCR）为100%，胰腺导管腺癌患者的肿瘤缩小了10%。在接受联合治疗的9名胰腺导管腺癌患者中，DCR为44%（4/9），与当前的标准二线治疗相当。JNT-517：公布1a期临床试验的初步数据Jnana Therapeutics公司公布了其潜在“first-in-class"口服小分子抑制剂JNT-517在健康受试者中的积极早期临床数据。JNT-517靶向苯丙氨酸转运体SLC6A19上的别构位点，旨在治疗苯丙酮尿症（PKU）患者，无论其年龄或基因型如何。PKU由苯丙氨酸羟化酶（PAH）缺乏引起。苯丙氨酸是存在于所有含蛋白质食物中的一种氨基酸，而PAH是分解苯丙氨酸所必需的酶。当PAH缺乏或功能缺陷时，苯丙氨酸将在血液中积累至异常高的毒性水平。如果不及时治疗可能导致进行性和严重的神经功能损伤和神经心理并发症。SLC6A19是一种转运蛋白，负责肾脏对苯丙氨酸的重吸收至血液中。JNT-517通过抑制SLC6A19来阻止阻止肾脏对苯丙氨酸的重吸收，提供了一种潜在疗法来降低血液苯丙氨酸水平。此前，该候选疗法已获得了FDA授予的罕见儿科疾病认定。此次公布的结果显示，JNT-517在健康受试者中的安全性和耐受性良好，没有严重的不良事件。此外，JNT-517被证实能够抑制SLC6A19，并导致苯丙氨酸的排泄增加。ADS051：公布1b期临床试验数据Adiso Therapeutics公司公布了其口服中性粒细胞运输和激活小分子调节剂ADS051治疗中度至重度活动性溃疡性结肠炎（UC）患者的早期临床数据。ADS051是一种作用局限于肠道、全身暴露有限的疗法，能够解决中性粒细胞介导的组织损伤——这是UC的一种病理学标志。此次公布的结果显示，ADS051安全且耐受性良好，并显示出积极的药理活性信号。AX-158：公布1期临床试验数据Artax Biopharma公司公布了其潜在“first-in-class"的口服免疫调节剂AX-158用于治疗T细胞介导疾病的早期临床数据。Nck是一种能直接放大T细胞受体上T细胞信号的蛋白质，有助于治疗T细胞介导的疾病。AX-158是一种Nck SH3.1结构域抑制剂，可选择性地阻断Nck在T细胞中的作用。AX-158的免疫调节作用有助于免疫系统保持健康控制并消除T细胞介导疾病的潜在驱动因素。临床前数据表明AX-158不具有免疫抑制作用，因此不会影响免疫系统对外来病原体和感染产生强烈反应的能力。此次公布的结果显示，AX-158在所有剂量下均具有良好的耐受性，其药代动力学特征和生物利用度数据支持其每日一次的口服给药方案。CSTI-500：公布1期临床试验数据ConSynance Therapeutics公司公布了其用于治疗Prader-Willi综合征的三重单胺再摄取抑制剂CSTI-500的积极1期临床试验数据。PWS是一种罕见的遗传性神经系统疾病，其许多症状是由下丘脑功能障碍引起的。下丘脑是大脑的一部分，它控制着睡眠-清醒状态的稳定性并能调节饥饿和饱腹感之间的平衡。下丘脑功能障碍会导致PWS患者的两个主要神经精神症状——脾气暴躁和食欲过盛。CSTI-500旨在以最佳比例调节血清素、多巴胺和去甲肾上腺素的再摄取——这三种重要的神经递质参与许多神经精神和神经功能，例如进食行为、情绪和睡眠，有望安全有效地减轻食欲过盛和脾气暴躁。此次公布的数据显示，CSTI-500表现出很强的安全性，没有出现严重的不良事件。此外，其药代动力学结果与早期在健康受试者中的观察结果非常吻合。目前，CSTI-500正准备进入2期临床试验。
