Alentis to receive US$355 million initial payment and up to US$1.2 billion in commercial milestones, with global profits shared Alentis将获得3.55亿美元的初始付款,以及高达12亿美元的商业里程碑付款,并共享全球利润MELBOURNE, Australia and BASEL, Switzerland 澳大利亚墨尔本和瑞士巴塞尔, ,Oct. 4, 2026 2026年10月4日/PRNewswire/ -- CSL and Alentis Therapeutics today announced they have entered into an exclusive global collaboration agreement to co-develop and co-promote lixudebart, which has the potential to become a first-in-class therapy targeting claudin-1 across a range of kidney, liver and other diseases.. /美通社/ -- CSL与Alentis Therapeutics今日宣布,双方已达成一项独家全球合作协议,共同开发并推广lixudebart。该药物有望成为首个靶向claudin-1的同类首创疗法,适用于多种肾脏、肝脏及其他疾病。Lixudebart is currently being evaluated in the ongoing Phase 2 RENAL trial in patients with ANCA (antineutrophil cytoplasmic antibodies)-associated vasculitis with rapidly progressive glomerulonephritis (AAV-RPGN), a rare and potentially life-threatening autoimmune disease that can cause irreversible kidney damage and end-stage renal disease.. Lixudebart 目前正在针对患有抗中性粒细胞胞浆抗体(ANCA)相关性血管炎伴急进性肾小球肾炎(AAV-RPGN)的患者进行的二期 RENAL 临床试验中接受评估。AAV-RPGN 是一种罕见且可能危及生命的自身免疫性疾病,可导致不可逆的肾脏损伤和终末期肾病。With a novel mechanism of action, lixudebart exerts potent anti-inflammatory and anti-fibrotic effects to potentially prevent and reverse organ damage in ANCA-associated vasculitis (AAV) and numerous other kidney, liver and lung diseases. The ongoing phase 2 trial is designed to translate these mechanistic effects into meaningful clinical impact. 利克德巴特凭借新颖的作用机制,发挥强效的抗炎和抗纤维化作用,有望预防并逆转ANCA相关性血管炎(AAV)以及多种其他肾脏、肝脏和肺部疾病中的器官损伤。正在进行的2期临床试验旨在将这些机制性效应转化为具有临床意义的实质性影响。. 。The collaboration brings together Alentis' scientific expertise as the leading clinical-stage biopharmaceutical company targeting claudin-1 and CSL's global development and commercialisation capabilities in nephrology, with a shared goal of bringing innovative and highly impactful treatment options to patients with rare kidney and liver diseases. 此次合作将阿伦蒂斯(Alentis)作为靶向紧密连接蛋白-1(claudin-1)的领先临床阶段生物制药公司的科学专长,与CSL在肾脏病领域的全球开发和商业化能力相结合,共同致力于为患有罕见肾脏和肝脏疾病的患者带来创新且具有高影响力的治疗选择。In addition to AAV-RPGN, the two companies will advance lixudebart as a novel treatment for focal segmental glomerulosclerosis (FSGS), a rare progressive kidney disease, and for primary sclerosing cholangitis (PSC), an autoimmune chronic liver disease.. 除了AAV-RPGN之外,两家公司还将推进lixudebart作为一种新型疗法,用于治疗局灶节段性肾小球硬化(FSGS,一种罕见的进行性肾脏疾病)和原发性硬化性胆管炎(PSC,一种自身免疫性慢性肝病)。'This partnership enables us to dramatically accelerate the development of lixudebart in several indications in parallel,' said Dr Mark Pruzanski, Chief Executive Officer of Alentis Therapeutics. 'We are convinced CSL's demonstrated clinical development and commercialisation capabilities in AAV and kidney diseases makes them the right partner to bring lixudebart to patients. Alentis Therapeutics 首席执行官 Mark Pruzanski 博士表示:“此次合作使我们能够大幅加速 lixudebart 在多个适应症上的并行开发。我们深信,CSL 在 AAV(腺相关病毒)疗法和肾脏疾病领域展现出的临床开发与商业化能力,使其成为将 lixudebart 带给患者的理想合作伙伴。”More broadly, this furthers the validation of claudin-1 as a novel therapeutic target and we are excited about the potential to accelerate the advancement of our other clinical stage assets and preclinical pipeline.'. 更广泛而言,这进一步验证了claudin-1作为一种新型治疗靶点的有效性,我们对有望加速推进其他处于临床阶段的资产及临床前管线的发展感到振奋。'Patients diagnosed with ANCA-associated vasculitis with rapidly progressive glomerulonephritis face rapid kidney function decline, leaving them at risk of irreversible damage even with currently available treatments,' said Dr Bill Mezzanotte, EVP, Head of R&D, CSL. 'We believe lixudebart has the potential to become an important new therapeutic option to help improve kidney function and prevent progression to end-stage kidney disease, first in AAV-RPGN and hopefully also in focal segmental glomerulosclerosis, while potentially showing similar benefit on liver function in primary sclerosing cholangitis. “被诊断为ANCA相关性血管炎伴快速进展性肾小球肾炎的患者面临肾功能迅速下降的风险,即使使用目前可用的治疗方法,他们仍存在不可逆损伤的风险,”CSL执行副总裁兼研发负责人Bill Mezzanotte博士表示。“我们相信,lixudebart有望成为一种重要的新治疗选择,有助于改善肾功能并防止进展至终末期肾病,首先应用于ANCA相关性血管炎伴快速进展性肾小球肾炎(AAV-RPGN),并希望未来也能应用于局灶节段性肾小球硬化症(FSGS),同时在原发性硬化性胆管炎(PSC)中也可能对肝功能显示出类似的益处。”Our partnership with Alentis reflects CSL's commitment to building a leading global nephrology franchise, and our strategic intent to create high-value external partnerships.'. 我们与Alentis的合作体现了CSL致力于构建全球领先的肾脏病学业务板块,以及我们建立高价值外部合作伙伴关系的战略意图。Under the agreement, CSL and Alentis will jointly develop and co-promote lixudebart. CSL will make an initial payment to Alentis of US$355 million, with Alentis eligible to receive up to an additional US$1.2 billion in commercial milestone payments. In addition to these payments, CSL will fully fund the completion of the ongoing Phase 2 RENAL trial and planned Phase 3 trial in AAV-RPGN, the Phase 2 trials in FSGS and PSC and other supporting development activities. 根据协议,CSL与Alentis将联合开发并共同推广lixudebart。CSL将向Alentis支付3.55亿美元的初始付款,Alentis还有资格获得高达12亿美元的额外商业里程碑付款。除这些付款外,CSL还将全额资助正在进行的AAV-RPGN二期RENAL试验和计划中的三期试验、FSGS和PSC的二期试验以及其他支持性开发活动的完成。Once commercialised, global profits will be shared 55 per cent to CSL and 45 per cent to Alentis.. 一旦实现商业化,全球利润将由CSL获得55%,Alentis获得45%。About AAV-RPGN 关于AAV-RPGNANCA (antineutrophil cytoplasmic antibodies)-associated vasculitis with rapidly progressive glomerulonephritis (AAV-RPGN) is a rare, severe and potentially fatal autoimmune disease in which the body's immune system attacks small blood vessels in the kidney. RPGN is characterized by rapid loss of kidney function over a very short period (days to weeks). 伴快速进展性肾小球肾炎的抗中性粒细胞胞质抗体(ANCA)相关性血管炎(AAV-RPGN)是一种罕见、严重且可能致命的自身免疫性疾病,其特点是机体免疫系统攻击肾脏中的小血管。快速进展性肾小球肾炎(RPGN)的特征是在极短时间(数天至数周)内肾功能迅速丧失。Despite potent immunosuppressive treatment, most patients develop significant or total loss of kidney function.. 尽管接受了强效的免疫抑制治疗,大多数患者仍会出现显著或完全的肾功能丧失。About Lixudebart 关于 LixudebartLixudebart (formerly known as ALE.F02) is an investigational monoclonal antibody that selectively targets exposed claudin-1, a key driver of inflammatory and fibrotic signalling pathways in numerous fibrotic diseases of the kidney, liver, lung, intestine and other solid organs. In an interim analysis of 26 patients with AAV-RPGN in the ongoing Phase 2 RENAL trial, lixudebart showed promising improvement in kidney function as assessed by eGFR and proteinuria at 24 weeks. Lixudebart(前称 ALE.F02)是一种在研的单克隆抗体,选择性靶向暴露的紧密连接蛋白-1(claudin-1),后者是肾脏、肝脏、肺部、肠道及其他实体器官多种纤维化疾病中炎症和纤维化信号通路的关键驱动因子。在正在进行的二期 RENAL 试验中,对 26 例伴有抗中性粒细胞胞浆抗体相关快速进展性肾小球肾炎(AAV-RPGN)的患者进行的中期分析显示,在第 24 周时,根据估算肾小球滤过率(eGFR)和蛋白尿评估,lixudebart 在改善肾功能方面展现出令人鼓舞的效果。In the Phase 1b FEGATO trial in 41 patients with advanced F3/F4 liver fibrosis, lixudebart demonstrated improved liver function at 6 weeks. In both studies lixudebart showed dose-dependent claudin-1 target engagement, along with a favourable safety and tolerability profile. Lixudebart has been granted Orphan Drug designation by the FDA for the treatment of Idiopathic Pulmonary Fibrosis (IPF).. 在针对41例晚期F3/F4级肝纤维化患者的FEGATO I期b临床试验中,lixudebart在治疗6周后显示出肝功能改善。在这两项研究中,lixudebart均表现出剂量依赖性的claudin-1靶点结合活性,并具有良好的安全性和耐受性。美国食品药品监督管理局(FDA)已授予lixudebart用于治疗特发性肺纤维化(IPF)的孤儿药资格。About CSL 关于CSLCSL CSL(ASX:CSL; USOTC:CSLLY) is a leading global biopharma company with a dynamic portfolio of lifesaving medicines, including those that treat haemophilia and immune deficiencies, vaccines to prevent influenza, and therapies in iron deficiency, dialysis and nephrology.
