导语:在EV-302研究改写晚期尿路上皮癌(UC)治疗史后(详见系列文章第5-8期),治疗革命的焦点正快速转向更早阶段——围手术期治疗。随着EV、维迪西妥单抗等ADC药物在转移性尿路上皮癌(mUC)的突破,研究者开始探索其在肌层浸润性膀胱癌(MIBC)新辅助/辅助治疗的潜力。这一战略转移,或将彻底改变膀胱癌“手术+化疗”的传统模式,开启精准治疗新时代。
张瑞赟 教授:ADC药物能否在围手术期治疗中完全替代传统化疗?未来应重点探索ADC联合免疫治疗,还是与化疗/其他药物联用?如何重构“新辅助-手术... more
导语:随着EV+P方案成为晚期尿路上皮癌(UC)一线治疗新标准,Nectin-4的H评分与PD-L1的CPS评分是否需作为临床常规检测?这一问题的答案,或将直接影响治疗精准性与患者经济负担。
张瑞赟 教授:EV-302研究中,Nectin-4与PD-L1的表达数据是否支持生物标志物检测的前置必要性?临床实践中如何平衡检测成本与治疗获益?
张顺 教授:这项研究采用了特殊的评分方法,通过计算染色强度和阳性细胞比例的加权总和来确定表达水平。研究中将H≥275定义为高表达,H≥150为阳性标准。虽然研究... more
导语:2024年ASCO年会,EV-302研究再次交出终极答卷:中位OS延长至33.8个月,完全缓解(CR)患者24个月持续缓解率74%。这不仅将晚期UC的生存标准推至新高度,更首次揭示“临床治愈”的可能性。
张瑞赟 教授:EV+P方案的长期随访数据是否验证了生存优势的持久性?完全缓解患者能否真正实现“长生存治愈”?
朱一平 教授:1. OS再创新高:时间累积效应放大生存优势中位OS从首次分析的31.5个月延长至33.8个月(对照组维持15.9个月),死亡风险降低49%(HR=0.51)。随着随... more
导语:在EV-302研究具有颠覆性的亚组数据:内脏转移患者(尤其是肝转移)的生存获益。这类患者曾被视为“治疗黑洞”——传统化疗中位OS不足12个月,免疫单药易诱发超进展。但EV-302研究显示,EV联合帕博利珠单抗(EV+P)将肝转移患者的死亡风险降低47%(HR=0.53),中位OS突破18个月,彻底改写了这一群体的生存逻辑。
张瑞赟 教授:为何EV+P方案能在传统“治疗禁区”中实现突破?其亚组数据对临床实践有何指导意义?
从“泛表达靶点”到“持久穿透力”朱一平 教授:内脏转移病灶的快速进展特... more
导语:在EV-302安全性方面,临床医生将面临“疗效惊艳但管理陌生”的新问题。随着国内EV获批上市,如何平衡疗效与安全性成为实践核心命题。
张瑞赟 教授:EV+P方案的安全性数据如何解读?面对皮肤毒性、神经损伤等独特不良事件,临床应如何科学管理?
盛锡楠 教授:EV+P的毒性谱与传统化疗不同,但严重不良事件比例可控。皮肤反应和神经毒性虽总体发生率高(60%-70%),但≥3级严重事件发生率分别为15%和6.8%,显著低于化疗组血液学毒性。这些毒性虽为临床新挑战,但严重程度未超越传统治疗。相比化疗... more

导语:EV-302研究不仅源于药物组合的科学协同,更归功于研究设计的精密策略——从分层随机化到统计学动态调整,每一步都暗藏“破局密码”。
张瑞赟 教授:EV-302研究如何通过设计策略突破传统瓶颈?其经验对国产创新药研发有何启示?
张顺 教授:分层设计——精准控制混杂变量EV-302研究采用顺铂耐受性、PD-L1表达(CPS≥10)、肝转移状态三重分层因素,确保组间基线均衡,消除疗效评估偏差。肝转移亚组(占人群22%-23%)接受EV联合PD-1抑制剂治疗后,死亡风险降低55%(HR=0.45... more
导语:EV-302研究结果终结了化疗的“30年统治”, “靶向杀伤释放抗原,免疫激活形成记忆” 的协同循环,让 “去化疗化” 成为可能。
张瑞赟 教授:EV-302研究为何能在一线治疗中取得历史性突破?EV-302的成功对后续研究有何启示?为何其他阳性研究(如901试验)却陷入尴尬?如何让EV-302的成功经验惠及更多患者?朱一平 教授:1. 黄金组合的“双向奔赴”EV(靶向Nectin-4的ADC)与帕博利珠单抗(PD-1抑制剂)的联用,像高手间的相互成就。靶点精准:EV通过Nectin-4靶... more
