根据协议,赛诺菲将获得EarendilLabs自主研发的两种双特异性抗体HXN-1002及HXN-1003的全球独家授权。这两种抗体均基于EarendilLabs专有的人工智能和高通量发现与研究平台进行开发,旨在为结肠炎、皮肤炎症等自免疾病提供治疗选择。

作为回报,EarendilLabs将获得1.25亿美元的预付款,并有资格获得总计高达17.2亿美元的开发和商业里程碑付款,其中包括5000万美元的近期付款。此外,EarendilLabs有资格获得从高个位数到低两位数不等的产品销售额的分级版税。(注:总交易额18.45亿美元,约合人民币134亿元)

01.

重金押注AI双抗

HXN-1002是一款靶向α4β7和TL1A的双特异性抗体。通过同时抑制两个经临床验证的靶点,HXN-1002有望显著提高临床疗效,尤其适用于难治性患者。HXN-1002旨在为中重度溃疡性结肠炎(UC)和克罗恩病(CD)患者提供治疗选择。

HXN-1003是一款靶向TL1A和IL23的双特异性抗体。这两个靶点是多种人类自身免疫性疾病中炎症反应的核心驱动因素。通过同时阻断这两条通路,该药已在结肠炎和皮肤炎症的临床前模型中展现出协同效应,有望解决尚未满足的治疗需求。

这两款双抗均是基于EarendilLabs公司的人工智能和高通量发现与研究平台开发而成。而EarendilLabs的背后则是一家中国AI+药物研发公司:华深智药。

根据公开信息,EarendilLabs为华深智药的关联公司,总部位于美国。通过结合先进的机器学习、生成性蛋白质工程和高通量实验技术,EarendilLabs及华深智药简化了药物发现和研究过程,旨在显著加快药物开发。EarendilLabs的专有集成框架能够精确优化基于蛋白质的生物制剂的功能、可制造性和可开发性,具有一流潜力。

华深智药作为一家专注于AI+高通量抗体优化公司,由清华大学人工智能产业研究院孵化,计算生物学专家彭健创立于2021年。成立至今,公司已开发多种蛋白药物设计与建模的创新算法,其AI抗体设计平台HelixonDesign能够大规模地模拟分子间相互作用,高效地对多靶点抗体进行设计,大幅缩短研发周期。

2023年2月,资深新药研发科学家朱祯平博士加入华深智药,以联合创始人加入公司并出任总裁及联席首席执行官,负责华深智药创新药物的研发和产品管线推进、战略制定与运营。此后,华深智药进一步加大了对于药物研发管线的投入。

关于此次交易,EarendilLabs首席执行官彭健博士表示,很高兴与全球免疫学领导者赛诺菲合作推进HXN-1002和HXN-1003的开发。公司平台通过先进的预测蛋白模型和高通量生物学,彻底改变了双特异性抗体的发现和开发。此次合作突显了Earendil开发潜在一流候选产品的能力,旨在改变患者护理。

EarendilLabs总裁兼联席首席执行官朱祯平博士表示,自身免疫性疾病以慢性疾病过程和高复发率为特征,严重影响了患者的生活质量,现有药物疗效有限,存在未满足的医疗需求。相信赛诺菲在自免领域的专业知识将大大加快HXN-1002和HXN-1003的开发,最终尽快将这些可能改变生活的治疗方法带给全球患者。

02.

TL1A双抗研发处于早期阶段

自免领域是赛诺菲的重要布局方向。2025年1月,赛诺菲研发主管HoumanAshrafian博士在制药业全年收益电话会议上再次重申,公司的战略是成为“首屈一指的免疫学巨头”。

2025年3月,赛诺菲与DrenBio签署了一项价值16亿美元的协议,开发一种针对B细胞非霍奇金淋巴瘤的CD20靶向抗体。4月,赛诺菲与Nurix达成了一项价值4.8亿美元的自身免疫交易,该交易包含一种曾经无法用药的转录因子的降解剂。 

TL1A作为近两年自免领域的热门靶点,优势在于同时调控炎症和纤维化通路,适应症扩展潜力大。TL1A(TNF样配体1A)是肿瘤坏死因子家族的重要成员,作为一种2型跨膜蛋白,在多种免疫细胞和非免疫细胞中均有表达。TL1A通过与死亡受体3(DR3)结合并激活下游信号传导,在先天和适应性免疫稳态的维护中发挥重要作用。

研究表明,TL1A靶点潜在效果跨多个不同的疾病,如炎症性疾病、自身免疫性疾病,且具有直接抗纤维化作用,与炎症性肠病(IBD)、类风湿关节炎(RA)、特应性皮炎、系统性红斑狼疮、哮喘、银屑病等多种自身免疫性疾病的发生和发病机制相关。

目前,全球范围内尚无靶向TL1A的药物获批上市,但已有多个针对TL1A靶点的候选药物进入临床试验阶段,并显示出积极结果。其中,TL1A单抗的研发进展较快,已有8个TL1A单抗处于临床研究,其中默沙东的tulisokibart和辉瑞的PF-06480605处于III期临床。TL1A双抗则仍处于早期研发阶段,辉瑞研发的PF-07261271是当前唯一处于临床阶段的TL1A双抗。

对于赛诺菲来说,此次交易具有多重价值。由于2025年初赛诺菲收购自Kymab的哮喘药物II期临床试验失败,导致其免疫管线出现空缺。此次交易快速补充了赛诺菲在中重度IBD等细分市场的管线布局,有望为未来收入增长提供新动力。

此次交易也是跨国药企与中国本土AI药企合作的典型案例,契合赛诺菲的“AI优先”战略。据悉,此前赛诺菲与FormationBio、OpenAI的合作已初步验证AI在分子优化中的价值。

截至目前,加上今年3月收购DrenBio的髓系细胞双抗DR-0201,赛诺菲2025年已投入近40亿美元布局自免领域。其目标是通过“双抗+AI”组合,构建涵盖炎症性肠病、狼疮、银屑病的全管线矩阵,挑战艾伯维和强生的统治地位。
