2021年4月，一笔不起眼的BD交易在美国悄然完成。 Celcuity宣布与辉瑞达成全球许可协议，获得泛PI3K-mTORC1/2抑制剂gedatolisib在全球范围内的开发和 商业化权益。 作为一款泛PI3K与mTORC1/2双重抑制剂，它对p110α/β/γ/δ四种PI3K催化亚型以及mTORC1、mTORC2 均保持低纳摩尔级活性。这意味着，Gedatolisib可以一次性切断PI3K/AKT/mTOR（PAM）轴的全部关 键节点，而不仅是其中某一条分支。 由于gedatolisib尚处早期阶段，属于被辉瑞放弃的管线，因此交易价格极其划算：前期付款1000万美 元，其中500万美元现金支付，另外500万美元以股权支付即可。 即便加上后续3.3亿美元的里程碑款，总金额不超过3.5亿美元。这样的BD，在动辄十亿、百亿交易的面 前，很难引发市场关注。 只是谁也没想到，4年后的今天，剧情让辉瑞有些难绷。 7月28日，Celcuity宣布，gedatolisib在III期VIKTORIA-1临床PIK3CA野生型队列中取得积极初步结果： gedatolisib三联疗法在患者中，达到统计学显著且具有临床意义的PF ...
