摘要:

达雷木单抗,是一种单克隆CD38单抗,已获得批准用于治疗骨髓瘤,但其用于AL淀粉样变的疗效和安全性尚未完全明确。

研究人员开展一项前瞻性的II期试验,研究达雷木单抗单药疗法用于治疗轻链淀粉样变(AL)的安全性、耐受性和血液学及临床反应。共招募了24位既往治疗过的AL患者。

予以所有患者达雷木单抗(16 mg/kg)治疗,静脉输注,1次/周,连续用8周,随后每2周一次,24周后,改为4周一次,直至病情进展或出现不可耐受的毒性,共24个月。

大多数患者接受了大剂量美法仑和干细胞移植以及/或蛋白酶体抑制剂治疗。既往治疗和招募进该试验的间隔中位时间为9个月。无3-4级输液相关反应发生。

最常见的3级及以上不良反应事件有呼吸道感染(4例,18%)和房颤(4例,18%)。

86%的患者获得血液学完全和较好的部分缓解。首次和最佳血液学缓解的中位时间分别为4周和3个月。15位累及肾脏的患者中有10位(67%)获得肾脏缓解,14位累及心脏的患者中有7位(50%)获得心脏缓解。

总而言之,达雷木单抗用于复发性AL淀粉样变患者的耐受性良好,可使患者获得快速深层次的血液学缓解和器官缓解。

由此可见,很大比例的AL淀粉样变性患者存在甲状腺功能减退症,主要为亚临床甲状腺功能减退,其具有生存劣势。在这些患者中进行TSH的常规评估是很有必要的。

Blood:不能进行NT-proBNP检查的情况下,也可对AL淀粉样变患者分期了

中心点:采用为阈值BNP>81pg/mL和TnI>0.1ng/mL的AL淀粉样变生物标志物分期系统与以NT-proBNP为基础的系统密切相关。新的以BNP为基础的分期系统可预测AL淀粉样变患者的总体存活率。摘要:免疫球蛋白轻链淀粉样变(AL淀粉样变)是由于轻链错误折叠导致的,形成可溶性的毒性聚合物,在组织器官中沉积导致器官功能障碍。存活的主要决定因素是心脏受累。目前的分期系统采用N末端
