病变骨髓中的缺氧情况为多发性骨髓瘤提供了新的治疗靶点。CLIN CANCER RES近期发表了一篇文章,研究evofosfamide联合地塞米松,联合硼替佐米以及地塞米松质量复发/难治性多发性骨髓瘤的效果。

研究共纳入59名患者,31名患者接受了evofosfamide联合地塞米松治疗,28名患者接受了evofosfamide,硼替佐米联合地塞米松治疗。患者接受过很多的其他治疗,接受过治疗的中位数为7。所有患者都接受过硼替佐米和免疫调节剂治疗。研究主要确定MTD,治疗毒性和有效性。研究结果表明,MTD为340 mg / m 2 evofosfamide 联合地塞米松,更高剂量时出现剂量限制性粘膜炎。接受evofosfamide,硼替佐米和地塞米松联合治疗的患者没有出现剂量限制性毒性(DLT),推荐II期剂量建为340 mg / m 2。最常见的≥3级不良事件(AE)为血小板减少症(25例),贫血症(24例),中性粒细胞减少症(15例)和白细胞减少症(9例)。42名(71%)患者出现皮肤毒性。evofosfamide 联合地塞米松组治疗反应包括1例非常好的部分反应(VGPR),3例部分反应(PR),2例轻微反应(MR),20例稳定疾病(SD)和4例疾病进展(PD),evofosfamide 联合硼替佐米以及地塞米松组治疗反应包括1例完全反应(CR),2 PR,1 MR,18 SD和5 PD。疾病稳定超过80%,总生存期延长到11.2个月。

文章最后认为,Evofosfamide 340 mg / m 2可以每周两次给药,联合或不联合硼替佐米。在接受过治疗的复发难治性多发性骨髓瘤患者中具有临床活性。
