早期治疗方案中对来那度胺耐药的复发或难治的多发性骨髓瘤患者需要新的有效疗法。在2MM-014研究中,研究人员对来那度胺治疗耐药的复发或难治性多发性骨髓瘤(RRMM)患者进行了评估,评价了泊马度胺、低剂量地塞米松和达雷木单抗的安全性和疗效,研究结果已发表于Leukemia

这些患者之前接受过一至两次治疗,从第1-21天每天接受泊马度胺4 mg,每周接受地塞米松40 mg28天周期)。达雷木单抗16mg/kg按标给药。主要终点是总反应率(ORR);次要终点包括无进展生存(PFS)和安全性。

 

根据方案,所有患者(N = 112)在最近的先前方案中接受了来那度胺(75.0%的患者对来那度胺耐药)。ORR77.7%(来那度胺难治性患者为76.2%);中位随访为17.2个月。中位PFS未达到(1PFS75.1%)。最常见的血液学3/4级治疗不良事件是中性粒细胞减少症(62.5%)。31.3%的患者出现3/4感染,包括13.4%3/4级肺炎。

综上所述,这些结果表明,对于RRMM患者,甚至是来那度胺治疗失败的患者,应尽早使用基于泊马度胺的方案作为二线治疗,具有良好的安全性和有效性,表明没有必要改变免疫调节剂药物。
