礼来79%卵巢癌缓解率出自III期不会采用的剂量

礼来在ESMO大会上公布的亮眼缓解率测自4毫克/千克剂量;III期试验按3毫克/千克开展,该剂量下的联合治疗结果尚未发表。就在一天前,Genmab刚公布了同类载荷的III期阳性结果。

礼来董事长兼首席执行官戴维·里克斯。礼来在马德里举行的ESMO大会上公布了抗体偶联药物(ADC)候选药Sofe-M的临床数据。

在马德里举行的欧洲肿瘤内科学会(ESMO)年会上,今天被引用最多的那个数字是真实的,但它并不是礼来−2.12% — 礼来, down 2.12 percent today将用来申报的数字。礼来10月24日报告称,sofetabart mipitecan(Sofe-M)联合现有抗癌药贝伐珠单抗,在铂敏感卵巢癌女性患者中取得79%的确认缓解率,且全部患者疾病均得到控制 1。该研究测试的剂量为4毫克/千克 1。而将支撑上市获批的III期临床项目按3毫克/千克开展,该剂量下的联合治疗缓解率尚未发表 1。

剂量才是关键

礼来自身的剂量选择数据解释了这次调整。单药治疗试验中,更低剂量下严重治疗相关不良事件和剂量下调均大幅减少,缓解率则保持持平 1。登上媒体头条的那项铂敏感结果,出自毒性更高的剂量组。它展示的是这个分子在最激进剂量下的能耐,而不是最终申报药物将交出的表现。

门槛不高,竞赛已进入倒计时

Sofe-M是一种"运毒"抗体:它结合几乎存在于所有卵巢肿瘤上的叶酸受体α,然后在细胞内释放细胞毒素依喜替康 1。它必须跨过的门槛并不高。在标准后续药物PARP抑制剂维持治疗之后,已发表的真实世界数据显示,再接受一轮铂类治疗的缓解率为41.9% 1。

丹麦抗体公司Genmab于10月23日宣布,采用同一依喜替康载荷的偶联药物rinatabart sesutecan在铂耐药卵巢癌的III期临床中同时达到两项生存终点,死亡风险降低57%,并表示将把这些数据提交监管机构 2。

Genmab的同一药物在铂敏感卵巢癌领域已有两项III期临床登记在案 2;艾伯维−0.06% — 艾伯维, down 0.06 percent today的Elahere已获批用于铂耐药适应症,该公司在铂敏感领域也有自己的试验,主要终点预计4月完成 3。阿斯利康已于9月加入同一场竞赛 3。这些在研新药共用同一类载荷,肿瘤对其中一种耐药,就可能对下一种也耐药,因此第一张批文比更高的数字更值钱 3。

真金白银已砸进工地

10月22日,礼来在弗吉尼亚州古奇兰(Goochland)为一座投资50亿美元的工厂破土动工,规模较最初计划扩大逾一倍。这是礼来首个在同一厂区内完成抗体偶联药物从原料到成品药全流程的生产基地,生产运营中嵌入人工智能和机器学习,预计2030年建成 4。

这也延续了礼来的建厂热潮,热潮中包括我们本月报道过的荷兰工厂 55。英伟达−0.54% — 英伟达, down 0.54 percent today新发布的开放式蛋白质设计模型RFD4-Proteina已向合作伙伴名单开放,名单中并不包括礼来 5;礼来自己的AI押注,则是1月宣布与英伟达共建的联合创新实验室,五年内投入最高可达10亿美元 5。

十个季度,礼来季度营收翻了一倍多

减肥药买单,12月必须给出交代

整条链的账单都由减肥药支付,而高盛预计,礼来10月29日发布财报时,这条营收线将再度走高 67。该行目前按28倍远期市盈率为礼来估值,而肥胖症之外的管线,必须从12月7日的投资者活动开始,证明这个倍数撑得住 6。

不妨把79%看作一场演示,而不是一款药。它将在3毫克/千克剂量下接受检验,与同一类载荷的对手正面竞争;在这个市场上,谁先申报,回报就归谁。10月29日的季报和12月7日的投资者日,就是礼来“第二幕”必须准时上演的舞台。
