NEJM:达拉他单抗联合来那度胺和地塞米松治疗不适合自体干细胞移植的骨髓瘤

来那度胺联合地塞米松是不适合自体干细胞移植的新诊断多发性骨髓瘤患者的标准治疗方法。本研究旨在确定添加达拉他单抗是否会显著降低该人群的疾病进展或死亡风险。

来那度胺联合地塞米松是不适合自体干细胞移植的新诊断多发性骨髓瘤患者的标准治疗方法。本研究旨在确定添加达拉他单抗是否会显著降低该人群的疾病进展或死亡风险。

 

我们随机分配了737例新诊断为多发性骨髓瘤的患者,这些患者不适合进行自体干细胞移植,接受达达拉他单抗联合来那度胺和地塞米松(达拉他单抗组)或来那度胺和地塞米松单独治疗(对照组)。一直治疗到疾病进展或不可接受的副作用发生为止。主要终点是无进展生存期。

 

中位随访28.0个月后,有240名患者发生了疾病进展或死亡(达拉他单抗组97名[26.4%],对照组143名[38.8%])。达拉他单抗组在30个月时未发生疾病进展的存活患者的比例为70.6%(95%置信区间[CI],65.0-75.4),对照组为55.6%(95%CI,49.5-61.3)(疾病进展或死亡的危险比为0.56;95%CI为0.43-0.73;P <0.001)。达拉他单抗组完全缓解或变好的患者比例为47.6%,对照组为24.9%(P <0.001)。达拉他单抗组中总计24.2%的患者与对照组中7.3%的患者,结果低于最小残留病阈值(每105个白细胞中有1个肿瘤细胞)(P <0.001)。最常见的3级或4级不良事件是中性粒细胞减少症(达拉他单抗组为50.0%,对照组为35.3%),贫血(11.8% VS 19.7%),淋巴细胞减少(15.1% VS 10.7%)和肺炎(13.7% VS 7.9%)。

 

综上所述,该研究结果表明,在新诊断为不适合自体干细胞移植的多发性骨髓瘤患者中,接受达拉妥单抗联合来那度胺和地塞米松治疗的患者疾病进展或死亡的风险明显低于单独接受来那度胺和地塞米松治疗的患者。达拉他单抗组中性粒细胞减少和肺炎的发生率更高。
