sotorasib

sotorasib这一资产在已发表文献里的地位相当扎实:I期研究入组129例KRAS G12C突变的晚期实体瘤患者,NSCLC亚组确认客观缓解率32.2%(19例),且无剂量限制性毒性或治疗相关死亡[3];II期单臂试验入组126例既往治过的晚期NSCLC,其中81.0%既接受过含铂化疗也接受过PD-1/PD-L1抑制剂[2];Lancet发表的III期试验在22个国家148个中心头对头比较多西他赛[6]。综述文献指出AMG510是首个获批临床使用的KRAS G12C靶向药[5],而38例患者的队列中45%检出推定耐药机制[4]。
这次ESMO26会上给出的是一次没有数字的情绪读数:@Tony_Calles直接发帖“Bye bye sotorasib”,并挂出#LCSM标签;@Rtsugitom则称“A much larger difference than anticipated”。两条现场帖都没有给出试验编号、试验名称或终点,所谓difference指的是什么对比也未披露。材料中唯一的会议摘要是divarasib在切除后II-IIIB期KRAS G12C+ NSCLC中进行中的III期试验“Krascendo 3”,随机分配至divarasib对比免疫治疗或观察,属于没有疗效结果的TIP[1]。因此只能判断现场情绪指向sotorasib的地位受到挑战,具体来源待确认。
主站新闻并未报道同一件事:它独立覆盖的是劲方医药pan-RAS分子胶GFH276在ESMO的数据,而非sotorasib的场次。新闻写到,GFH276的Ia期首次人体数据登上ESMO LBA后,公司股价当日盘中一度跌超8%:PDAC队列61例可评估患者确认ORR 41%(25/61)、DCR 91.8%,≥3级TRAE 14.8%(PDAC口径,全集27.5%),因TRAE停药率0%;NSCLC队列14例中11例可评估,确认ORR 45.5%,95%CI 20-72%。这与现场帖不是同一事件,两边信息无法互相印证,但合起来看,RAS赛道的竞争格局正在被重画。
拉远看,sotorasib的已发表证据全部集中在晚期后线治疗场景[2][3][6],而竞争者正沿两条轴推进:divarasib已把III期做到切除后II-IIIB期[1],以GFH276为代表的pan-RAS机制也已进入首次人体数据读出。若现场“bye bye”的情绪确实来自某项头对头或新一代读数,其来源未披露。需要提示的是,两条现场帖不带任何数字与标识,摘要为无结果的TIP,新闻数字只能照抄新闻本身,读者应等待全文与详细数据披露。
