Lancet Oncol:杜瓦鲁单抗联合曲美木单抗治疗晚期转移性肉瘤

2022-08-11 MedSci原创 MedSci原创

对于晚期或转移性肉瘤患者,杜瓦鲁单抗和曲美木单抗的联合方案是一种有效的治疗策略。

转移性肉瘤患者几乎没有标准的治疗选择。该研究旨在评估PD-L1药物杜瓦鲁单抗和抗CTLA-4药物曲美木单抗在多种肉瘤亚型中的疗效、安全性和肿瘤微环境的变化。

这是一项单中心的2期试验,招募了年满18岁、既往至少接受过一次系统治疗的、ECOG表现状态0-1分的晚期或转移性肉瘤患者,予以静脉杜瓦鲁单抗(1500 mg)和曲美木单抗(75 mg)治疗4个疗程,继以杜瓦鲁单抗单药维持(1次/4周),到12个月。主要终点是12周时的无进展生存率。


无进展生存率

2016年8月17日至2018年4月9日期间,共招募了62位患者,其中57位(92%)接受了研究治疗被纳入意向治疗人群。截止2020年4月30日,中位随访了37.2个月(范围 1.8-10.1),12周时的无进展生存率是49%(95% CI 36-61)。中位无进展生存期是2.8个月,12个月无进展生存率是28%,24个月无进展生存率是15%。中位总生存期是21.6个月。12个月总生存率是65%,24个月总生存率是49%。


总生存率

共报告了21例3-4级的治疗相关不良反应,最常见的有脂肪酶升高(7%)、结肠炎(5%)和肺炎(5%)。9位(16%)患者经历了治疗相关的严重不良反应事件。1位患者发生了5级的肺炎和结肠炎。


治疗相关不良反应

综上,对于晚期或转移性肉瘤患者,杜瓦鲁单抗和曲美木单抗的联合方案是一种有效的治疗策略,值得进一步开展相关试验进行评估。

Lancet oncol:纳武单抗联合或不联合伊匹单抗治疗转移性肉瘤的效果和安全性。

转移性肉瘤患者可选择的治疗方式有限。Nivolumab(纳武单抗)和ipilimumab(伊匹单抗)分别是靶向PD-1和CTLA-4的单克隆抗体。研究人员现对用纳武单抗单独或联合伊匹单抗用于治疗局部晚期、不可手术切除的或转移性肉瘤患者的效果和安全性进行研究。研究人员进行一多中心的、开放性的、非对比性的、随机2期研究,招募年满18岁的病理性确诊的肉瘤患者,且要求已有转移、或局部晚期、或不可手术切除,
