患者来源肿瘤类器官药物开发平台正式推出

圣迭戈, Oct. 23, 2019 (GLOBE NEWSWIRE) — Crown Bioscience今天宣布推出一个新的肿瘤类器官药物开发平台,有望显著提高临床前药物研发的预测性和速度。
该平台的初始阶段提供了首个市场有售的三维体外PDX源性类器官(PDXO)模型,由CrownBio超过2500多个人源肿瘤异体移植
(PDX)模型组成的独特特征模型库所生成。
PDXO在生物学上相当于具有高度预测性的体内PDX模型,两者都是癌症干细胞驱动疾病模型。PDXO的额外优势是体外系统固有的速度  和可扩展性,极其适合高通量、大规模筛选和同时对多个组合策略进行测试。这些3D 体外 模型的开发采用源自Clevers实验室的同类最佳Hubrecht类器官技术(HUB)协议,保证了鲁棒性和可靠的可转化性。
CrownBio获得了HUB的独家许可,可使用HUB的类器官技术提供临床前肿瘤药物开发和验证服务。
首先推出的PDXO模型涵盖10多种癌症类型。作为平台的第二阶段,HUB患者源性类器官(PDO)将于2020年第一季度通过CrownBio独  家提供。“在CrownBio,我们率先开发了人源肿瘤移植模型,”CrownBio首席科学官Henry  Li博士表示。“我们的新样本库中包括经完善描述和注释的类器官和相匹配的体内PDX模型,为临床前药物的发现提供了一个前所未有的转化工作流。从 体外体内 的真正无缝转化首次成为可能。我们的模型注释还提供自动发现生物标志物的机会,从而提高我们预测病人反应的能力。”患者相关的PDXO模型的其他优势包括保留其PDX肿瘤母本的基因、形态和病理生理属性。PDXO和PDX也显示相似的药理学特性。“我们非常高兴地看到HUB类器官技术被成功应用于PDX源性类器官的开发,并由CrownBio提供给整个行业的更大范围使用”,HUB首席  执行Rob Vries博士表示。“这一开创性的系统为访问病人源性 体外体内 模型的丰富样本库提供了渠道,在实际意义上将人数更多的癌症患者人口带入了实验室。”与常规2D和3D系统相比,HUB器类官作为一种临床前肿瘤学工具,已被证实能通过传代和高质量的分析读数提供稳定一致的生长。类器   官生物样本库的创建还能保证不失去原有属性,以便进行后续研究或重复研究。关于Crown Bioscience IncCrown Bioscience是JSR Life  Sciences下属企业,是一家全球性的药物研究和开发服务公司,提供转化平台以推进肿瘤学、炎症和代谢性疾病的研究。凭借广泛的相关模型和预测工具组合,Crown      Bioscience使客户能够提供卓越的临床候选药物。如需获取更多信息,请访问:https://www.crownbio.comhttps://www.jsrlifesciences.com关于HUBHubrecht类器官技术(HUB)是由荷兰皇家科学院和乌得勒支大学医学中心创建的一家组织。HUB利用的是Hans   Clevers教授的开创性研究成果,他发现了从不同疾病患者的组织中培育干细胞衍生人类“迷你器官”(HUB类器官)的方法。这些类器官是HUB生物样本库的一   部分,其特征是基因组测序、表达谱以及对已知和实验药物的敏感性,以建立一个将遗传及转录信息与药物反应性相关联的数据库。HUB   提供其HUB类器官技术的专利使用许可,以及HUB生物样本库类器官的访问许可,用于临床前药物的筛选、发现、开发和验证。此外,
HUB还在进行临床研究,以验证该技术作为伴随式诊断的用途。更多资讯请见 www.hub4organoids.eu
