复发性/难治性多发性骨髓瘤患者的福音:Elotuzumab疗法

2015-08-20 MedSci 译 MedSci原创

Elotuzumab是一种靶向淋巴细胞活化分子F7信号的免疫刺激单克隆抗体。它联合来那度胺和地塞米松治疗复发性/难治性多发性骨髓瘤患者在一项1b-2 期的研究中显示了良好的疗效。

背景:Elotuzumab是一种靶向淋巴细胞活化分子F7信号的免疫刺激单克隆抗体。它联合来那度胺和地塞米松治疗复发性/难治性多发性骨髓瘤患者在一项1b-2 期的研究中显示了良好的疗效。

研究方法:在这项三期研究中,受试者被随机分配接受elotuzumab加来那度胺和地塞米松(elotuzumab组)或来那度胺加地塞米松(对照组)治疗。复合观察终点是无进展生存期和总反应率。其最终结果是根据无进展生存期的中期分析产生的。

研究结果:Elotuzumab组纳入321名患者,对照组纳入325名。24.5个月的中位随访后,Elotuzumab组和对照组的一年无进展生存率分别为68%57%;两年无进展生存率分别为41%27%Elotuzumab组的中位无进展生存期为19.4个月,对照组为14.9个月(elotuzumab组进展或死亡的风险率为0.7095%CI 0.57-0.85p<0.001)。Elotuzumab组和对照组的总缓解率分别为79%66%P<0.001)。两组常见的34级不良反应有淋巴细胞减少症、中性粒细胞减少症、疲乏和肺炎。Elotuzumab组有33个病人(10%)出现输液反应,其中29个人被评为12级。

研究结论:复发性/难治性多发性骨髓瘤患者接受Elotuzumab、来那度胺、地塞米松联合治疗可将疾病进展或死亡的风险降低30%

Oncotarget:抗β2微球蛋白单克隆抗体能改善硼替佐米的耐药性

硼替佐米(BTZ)是目前用于治疗多发性骨髓瘤和套细胞淋巴瘤的一种蛋白酶抑制剂,因其存在许多副作用及耐药性,硼替佐米在临床的广泛应用受到限制。研究认为,细胞存活和死亡受到细胞凋亡和自噬活动的交叉调节,而且,自噬可以通过抑制半胱天冬酶的清除抑制细胞凋亡。近来研究发现,自噬在调节化疗药物耐量性中起很重要的作用,BTZ可以激活肿瘤细胞的自噬。BTZ诱导的细胞自噬对于BTZ耐药的乳腺癌细胞非常重要,提示抑制

Nature Medicine:免疫疗法在多发性骨髓瘤治疗中取得重大成功

近年来,免疫疗法成为了一种有前景的癌症治疗方法。遗传改造患者自身的免疫细胞来靶向肿瘤,现在这一策略在对当前无法治愈的一种恶性浆细胞疾病——多发性骨髓瘤的治疗中取得了重大成功。相关的研究结果发布在《自然医学》(Nature Medicine)杂志上。 患者在接受了自体干细胞移植后,体内再度被输入大约24亿个遗传改造T细胞。20名晚期患者其中的16人产生了显著的临床反应。科学家们发现患者能 够普遍
