• 双方的首要合作是在中国加速开发用于治疗实体肿瘤的2seventy的MAGE-A4项目

中国上海和美国马萨诸塞州剑桥市2022年10月27日 /美通社/ -- 药明巨诺（港交所代码：2126），一家独立的、专注于开发、生产及商业化细胞免疫治疗产品的创新型生物科技公司，与2seventy bio（纳斯达克代码：TSVT），一家领先的免疫肿瘤细胞治疗公司，今天宣布达成战略合作。双方将建立细胞治疗的转化及临床开发平台，在中国内地、香港及澳门地区加速T细胞免疫治疗产品的开发。

双方的首要合作将围绕2seventy的MAGE-A4 TCR项目，该项目用于治疗实体肿瘤，由2seventy与再生元（Regeneron）合作开发。MAGE-A4是癌-睾丸抗原MAGE家族的一员，这类抗原在多种实体肿瘤中均有表达。该项目旨在开发T细胞受体（TCR）疗法，用于治疗MAGE-A4阳性的实体肿瘤。

药明巨诺首席医学官Mark J. Gilbert博士表示："我们很高兴与2seventy bio携手，在中国共同开发MAGE-A4 TCR项目及其他潜在的产品。2seventy bio是一家业界一流的细胞治疗公司，拥有先进的技术及经验丰富的团队。此次战略合作将进一步发挥我们包括转化研究及临床开发在内的、世界一流的综合能力，我们期待加速开发更多具有突破性治疗价值的细胞免疫治疗产品，服务更多中国乃至全球的癌症患者。"

2seventy bio首席医学官Steve Bernstein表示："此次合作对于患者的真正价值，在于我们增强了快速测试、学习并推进我们创新细胞治疗项目的能力。药明巨诺对于中国患者未被满足的治疗需求、中国的注册事务流程、以及临床开发路径具有深入的洞察。借助此次合作机会，我们将彼此的独特优势经验相互结合，建立差异化的平台，从而实现我们的目标，即让创新治疗更快地惠及患者。"

根据协议条款，2seventy将授权药明巨诺在中国内地、香港及澳门地区开展MAGE-A4细胞治疗项目的权利，药明巨诺将负责其在中国的开发、生产及商业化，2seventy有权获得里程碑付款及基于产品收入的特许权使用费。此外，2seventy可将基于该合作项目而获得的早期临床数据用于在其他地区开发该产品。此次交易的完成尚待取得药明巨诺股东的批准，并满足其他惯例成交条件。

关于MAGE-A4项目

MAGE-A4是癌-睾丸抗原MAGE家族的一员，这类抗原在多种实体肿瘤中均有表达。我们构造了我们在与MediGene的合作中发现的一种高效的TCR，该TCR可识别HLA呈递的MAGE-A4多肽，并凭借我们CTBR12 TGF-beta"翻转"受体技术进一步增强这些T细胞的效力，将TGF-beta免疫抑制效应转化为T细胞的激活信号。再生元（Regeneron）和2seventy bio于2018年围绕此项目达成合作，目前双方正在合作开发。

With a deep understanding of the human body's immune response to tumor cells and how to translate cell therapies into practice, we're applying this knowledge to deliver next generation cellular therapies that focus on a broad range of hematologic malignancies, including the first FDA-approved CAR T cell therapy for multiple myeloma, as well as solid tumors. Our research and development is focused on delivering therapies that are designed with the goal to "think" smarter and faster than the disease. Importantly, we remain focused on accomplishing these goals by staying genuine and authentic to our "why" and keeping our people and culture top of mind every day.
