智通财经APP获悉，今日，Arvinas和辉瑞公司(PFE.US)宣布已为其联合开发的明星PROTAC分子vepdegestrant向美国FDA提交新药申请(NDA)，用于治疗既往接受过内分泌治疗的雌激素受体阳性(ER+)/人表皮生长因子受体2阴性(HER2-)、ESR1突变的晚期或转移性乳腺癌患者。
根据新闻稿，若获批，vepdegestrant将成为首个获美国FDA批准的PROTAC雌激素受体降解剂。值得一提的是，近10年前，在此类技术刚刚起步之时，药明康德就开始布局相关的能力和技术，并积累了大量成功经验。随着近年来对PROTAC了解的逐步深入，公司针对这类创新分子已搭建了完善的一体化赋能平台，集发现、合成、分析纯化和测试等能力于一体，目前已成功支持超过100款PROTAC分子的开发，其中超过20个分子顺利推进至临床阶段。
Vepdegestrant是一款潜在“first-in-class”的口服PROTAC降解剂，利用人体天然的蛋白质降解系统特异性地靶向并降解雌激素受体。它已经获得美国FDA授予的突破性疗法认定，用于治疗经治ER阳性、HER2阴性乳腺癌。
