由北京大学肿瘤医院郭军教授和上海交通大学医学院附属仁济医院黄翼然教授联合牵头开展的国内首个晚期肾癌免疫治疗关键Ⅲ期临床研究RENOTORCH研究成果在ESMO大会优选口头报告专场会议上首次发布,北京大学肿瘤医院盛锡楠教授报告了研究详细结果。全文同步获ESMO官方期刊《肿瘤学年鉴》(Annals of Oncology;影响因子:50.5;肿瘤领域全球排名TOP5的顶级期刊)发表,吸引了国际学者的广泛关注?/p>

RENOTORCH研究(NCT04394975)是一项随机、开放标签、多中心的Ⅲ期临床研究,共纳?21例既往未接受任何系统治疗的中高危不可切除或转移性肾细胞癌(RCC)患者,在全?7家临床中心开展,为我国首个晚期肾癌免疫治疗关键III期研究?/p>

截至2023??1日(中位随访时间?4.6个月),RENOTORCH期中分析结果显示,与舒尼替尼单药治疗相比,接受特瑞普利单抗联合阿昔替尼一线治疗可显著改善患者的无进展生存期(PFS)、提升客观缓解率(ORR),且安全性良好?/p>

  • 与舒尼替尼单药治疗相比,特瑞普利单抗联合阿昔替尼治疗可显著延长患者PFS,盲态独立中心阅片(BICR)评估的中位PFS?8.0 vs. 9.8个月,患者PFS延长?倍,疾病进展或死亡风险降?5%(HR=0.65?5%CI?.49-0.86;P=0.0028)。两?年和2年PFS率分别为62.7% vs. 45.4%?4.6% vs. 30.2%。值得一提的是,不同于既往同类型研究纳入全部风险水平的患者,本研究仅纳入中高危患者,仍取得了目前已报告的同类型研究中的最长中位PFS?/li>
  • 与舒尼替尼单药治疗相比,特瑞普利单抗联合阿昔替尼组患者的ORR更优(BICR评估的ORR?6.7% vs. 30.8%,P<0.0001),并且肿瘤缓解持续时间(DoR)更长(中位DoR为尚未达?vs. 16.7个月;HR=0.614?5%CI?.340-1.137)?/li>
  • 与舒尼替尼单药组相比,特瑞普利单抗联合阿昔替尼组具有明显的总生存期(OS)获益趋势(中位OS为尚未达?vs. 26.8个月),死亡风险降低39%(HR=0.61?5%CI?.40-0.92)?年和2年OS率分别为90.5% vs. 81.9%?1.8% vs. 63.2%?/li>
  • 安全性方面,特瑞普利单抗联合阿昔替尼的安全性和耐受性良好,未发现新的安全性信号?/li>

基于RENOTORCH研究积极结果,国家药品监督管理局(NMPA)已于今?月正式受理特瑞普利单抗联合阿昔替尼用于不可切除或转移性RCC患者一线治疗的新适应症上市申请?/p>

EXTENTORCH研究:全球首个SCLC PD-1免疫治疗Ⅲ期研究达到“双阳”结?/strong>

由吉林省肿瘤医院程颖教授牵头开展的特瑞普利单抗联合化疗一线治疗广泛期小细胞肺癌(ES-SCLC)的Ⅲ期研究EXTENTORCH以大会最新突破摘要(LBA)形式首次亮相迷你口头报告专场,吉林省肿瘤医院柳影教授在会上报告了研究详细结果?/p>

EXTENTORCH研究(NCT04012606)是一项随机、双盲、安慰剂对照、多中心的Ⅲ期临床研究,旨在比较特瑞普利单抗或安慰剂联合依托泊苷及铂类一线治疗ES-SCLC的有效性和安全性,共纳?42例既往未接受系统治疗的ES-SCLC患者,在全?1家临床研究中心联合开展。今?月,EXTENTORCH研究成功达到主要研究终点,特瑞普利单抗由此成为全球首个在ES-SCLC一线治疗Ⅲ期研究中达成OS和PFS双重主要终点的PD-1抑制剂?/p>

ENTENTORCH研究结果显示,相较单纯化疗,特瑞普利单抗联合化疗一线治疗并使用特瑞普利单抗维持治疗的ES-SCLC患者,PFS和OS均显著延长、且安全性良好,有望成为ES-SCLC的一线标准疗法?/p>

  • 最终PFS分析(中位随访时间为11.8个月)显示,与单纯化疗相比,特瑞普利单抗联合化疗显著改善患者PFS(研究者评估的中位PFS?.8 vs. 5.6个月),疾病进展或死亡风险降?3.3%(HR=0.667?5% CI?.539-0.824;P=0.0002)?/li>
  • 最终OS分析(中位随访时间为13.7个月)显示,与单纯化疗相比,特瑞普利单抗联合化疗生存获益显著(中位OS?4.6 vs. 13.3个月),死亡风险降低?0.2%(HR=0.798?5% CI?.648-0.982;P=0.0327)?/li>
  • 生物标志物探索分析发现,无论肿瘤突变负荷(TMB)状态如何,特瑞普利单抗联合化疗组的PFS和OS均有改善。此外,黏着?整合素信号通路突变与特瑞普利单抗联合化疗患者PFS和OS不良预后相关?/li>
  • 特瑞普利单抗联合化疗的安全性良好,未发现新的安全性信号?/li>

基于EXTENTORCH的积极结果,NMPA已于今年7月正式受理特瑞普利单抗联合依托泊苷和铂类用于ES-SCLC一线治疗的新适应症上市申请?/p>

特瑞普利单抗淋巴瘤研究:CR率达77.3%,为化疗不佳的I/Il期ENKTL患者带来更多治愈可?/strong>

由四川大学华西医院蒋明教授牵头开展的特瑞普利单抗联合放疗用于?Ⅱ期结外NK/T细胞淋巴瘤(ENKTL)的Ⅱ期临床研究(ChiCTR2100045147)在ESMO大会优选口头报告血液恶性肿瘤专场公布了详细结果?/p>

ENKTL是一种预后较差的侵袭性非霍奇金淋巴瘤,常见于亚洲人群,初诊时大多为Ⅰ/Ⅱ期。目前临床上常采用以L-天冬酰胺或培门冬酶为基础的多药化疗联合放疗(CCRT)的标准治疗方案治疗新诊断的局限性ENKTL,但无论采用何种放化疗联合方式,患?年生存率通常?0%-70%,并且对于多药化疗反应不佳的ENKTL患者,其生存期明显较低,临床需求亟待满足?/p>

该研究为一项多中心、开放、单臂的Ⅱ期临床研究,纳入了22例既往接受放疗2-3个周期后未达完全缓解(CR)的?Ⅱ期ENKTL患者。结果表明,特瑞普利单抗联合放疗可有效治疗对化疗反应不佳的I/II期ENKTL患者,提高临床疗效的同时又可以避免不必要的用药,并且安全性良好,未观察到其他毒性,值得进一步探索?/p>

  • 整体ORR?0.9%,CR率达77.3%?7例)?例达到PR?3.6%)?/li>
  • 中位随访时间?3个月,中位PFS和中位OS均尚未达到,2年PFS率和OS率分别为81.6%?5.0%?/li>
  • 安全性良好,未发?级以上治疗相关不良事件(TRAE)?/li>
  • 研究者还认为,早期使?8F-FDG PET/CT可以识别对以天冬酰胺酶为基础的化疗无应答的ENKTL患者?/li>
