云顶国际与日本LiberoThera达成战略合作协议
2021.02.01



Beijing, China and Tokyo, Japan, February 1st, 2021 – Biocytogen Pharmaceuticals (Beijing) Co., Ltd. (“Biocytogen”) and LiberoThera Co.,Ltd (“LiberoThera”) announced today that they have entered into an agreement for strategic collaboration on fully human therapeutic GPCR antibody development incorporating Biocytogen’s world-class antibody discovery expertise based on its fully human antibody RenMab® mouse platform with LiberoThera’s state-of-the-art antigen preparation capabilities.



中国北京和日本东京,2021年2月1日 – 云顶国际(北京)医药科技股份有限公司(下文简称云顶国际)与日本LiberoThera有限公司(下文简称“LiberoThera)今日共同宣布,双方将基于云顶国际世界先进的全人源转基因小鼠RenMab® 的抗体发现平台及LiberoThera杰出的抗原制备技术,开展针对全人GPCR抗体开发的战略合作。

The collaboration is expected to yield fully human GPCR antibodies for therapeutic use. Under the terms of the agreement, the companies will jointly work on the discovery research targeting an oncology-related GPCR until completion of in vivo evaluation studies as a first step. LiberoThera will provide antigens and assistance on in vitro screening while Biocytogen commits to use its RenMab® mouse platform for the GPCR antibody generation and lead the in vitro and in vivo evaluation. 

该合作旨在发现治疗型全人GPCR抗体。根据协议约定,第一阶段的合作双方将共同开展针对GPCR靶点的抗肿瘤抗体发现直到完成体内药效评价,确定先导抗体分子。LiberoThera负责抗原制备并参与抗体体外筛选,云顶国际则将利用其RenMab®小鼠平台开展GPCR抗体发现并通过体内药效评价技术完成先导抗体候选分子的筛选。


”GPCR monoclonal antibodies have great potential in various therapeutic areas. However, development of GPCR antibodies remains challenging due to the lack of understanding of the targets their biology and structure plus the technical hurdles in antigen design, preparation, modification, etc. With LiberoThera’s unique GPCR antigen preparation platform and its in-depth understanding of the target structure, we believe this strategic collaboration can break bottlenecks through leveraging the strengths of both ends to propel therapeutic GPCR antibody development forward.” said Yuelei Shen, Ph.D., president and CEO of Biocytogen.

云顶国际创始人、董事长和CEO沈月雷博士表示:“GPCR单克隆抗体在多种治疗领域具有非常大的应用潜力。然而,对该类靶点生物学特点及结构缺乏了解,再加上相关抗原设计、制备和修饰等相关技术的制约,针对该类靶点的抗体药物开发之路充满挑战。LiberoThera公司具有独特的GPCR抗原制备平台,并且对靶点结构有着深入的认识。我们相信本次战略合作可以充分结合双方平台的特点及优势,打破领域内现有的技术瓶颈,快速推进治疗型GPCR抗体的开发。”

“We are excited about this strategic collaboration as we see a great potential and synergy of Biocytogen’s innovative humanized models and streamlined antibody development platform together with LiberoThera’s membrane protein technologies.” said Toru Kanke, Ph.D., CEO of LiberoThera. “The fully human antibody RenMab® Mouse developed by Biocytogen together with the target knock-out strategy and single-cell screening platform will increase the fully human antibody repertoire against the targets. In combination with our structural antigen, discovery of antibodies with functional properties are highly expected. In addition, it is more likely to discover antibodies cross-reacting to orthologs of other species for convenient downstream evaluation in animal models. With its established in vivo testing capabilities, altogether, Biocytogen’s platform allows for a streamlined solution to improve the productivity of GPCR therapeutic antibody drug development. Collaboration between LiberoThera and Biocytogen would be a good match on confronting the challenges in the field.”


“我们非常高兴能与云顶国际展开战略合作。云顶国际创新性的人源化小鼠模型、一体化的抗体药物开发平台与我们独特的膜蛋白制备技术结合形成互补协同,有非常大的潜力。”LiberoThera公司CEO,Toru Kanke博士说道,“云顶国际自主研发的全人抗体鼠RenMab®结合靶点敲除策略及单细胞筛选平台能提高产生抗体的多样性,并且更有可能得到跨物种识别的抗体,大大方便了后续在动物模型中的筛选。云顶国际在体内药理药效筛选方面也已经建成了高效稳定的平台,这些优势结合起来使得云顶国际的平台具有整合性一体化的优势,能够提高治疗型GPCR抗体的开发效率。双方平台互补合作,携起手来一起面对领域内的挑战。
