Blood:达雷木单抗联合卡非佐米/地塞米松(Dkd)为来那度胺难治性多发性骨髓瘤患者带来新的希望

2019-05-22 QQ MedSci原创

复发性或难治性多发性骨髓瘤(RRMM)患者的治疗方案有限,存活预后较差。当下,越来越多的选用以来那度胺为基础的疗法作为MM的一线疗法,因此,需要针对来那度胺难治性患者开发新的有效疗法。

中心点:

无论既往是否采用过来那度胺治疗,达雷木单抗(Daratumumab)联合卡非佐米(carfilzomib)/地塞米松可诱导多发性骨髓瘤患者获得深层次、持久的缓解。

摘要:

复发性或难治性多发性骨髓瘤(RRMM)患者的治疗方案有限,存活预后较差。当下,越来越多的选用以来那度胺为基础的疗法作为MM的一线疗法,因此,需要针对来那度胺难治性患者开发新的有效疗法。

研究人员开展一个1b期研究,招募了85位既往治疗过1-3次(包括硼替佐米和免疫调节剂)的来那度胺难治性的MM患者,评估达雷木单抗联合卡非佐米和地塞米松(Dkd)用于该患者的疗效和安全性。

所有患者接受卡非佐米(初始剂量20mg/m2,随后递增至70mg/m2,每疗程的第1、8和15天给药)和地塞米松(40mg/周)治疗。达雷木单抗的给药方式:10位患者单次注射(16mg/kg,第1疗程的第一天给药),另75位患者予以分次注射(8mg/kg,第1疗程的第一、二天给药)。随后给药方式相同。患者既往治疗疗程中位值为2(1-4);60%为来那度胺难治性。

最常见的3/4级需紧急治疗的副反应有血小板减少(31%)、淋巴细胞减少(24%)、贫血(21%)和中性粒细胞减少(21%)。首剂单次注射和分次注射组分别有60%和43%的患者发生输液相关反应。总体缓解率达84%(79%为来那度胺难治性)。随访期间未达到中位无进展存活期(PFS);所有患者和来那度胺难治性患者的12个月PFS率分别为74%和65%。

综上所述,D-kd疗法用于多发性骨髓瘤患者,包括对来那度胺难治性的患者,耐受性良好,副反应率低,可诱导深度缓解和较高的PFS率。
