Lancet Oncol:伊布替尼联合BR与BR对比治疗rrCLL/SLL患者:随机对照双盲Ⅲ期研究

2017-10-17 梅斯医学 梅斯医学

研究背景与目的•CLL/SLL目前仍然难以治愈,多数患者在初始治疗后均会复发•苯达莫司汀联合利妥昔单抗(BR)常用于复发/难治患者的治疗•伊布替尼是首个每日一次口服BTK抑制剂,被NCCN指南优先推荐用于复发患者的治疗(1类推荐)•在一项1b期研究中,伊布替尼联合BR治疗CLL总缓解率达93%,36个月时PFS 70%•Ⅲ期研究HELIOS旨在评估伊布替尼联合BR与安慰剂联合BR对比治疗rrCLL

研究背景与目的

•CLL/SLL目前仍然难以治愈,多数患者在初始治疗后均会复发

•苯达莫司汀联合利妥昔单抗(BR)常用于复发/难治患者的治疗

•伊布替尼是首个每日一次口服BTK抑制剂,被NCCN指南优先推荐用于复发患者的治疗(1类推荐)

•在一项1b期研究中,伊布替尼联合BR治疗CLL总缓解率达93%,36个月时PFS 70%

•Ⅲ期研究HELIOS旨在评估伊布替尼联合BR与安慰剂联合BR对比治疗rrCLL/SLL患者的疗效及安全性

研究方法与入组人群

•国际多中心、随机、双盲、安慰剂对照Ⅲ期研究,入组时间:2012年9月-2014年1月,平均随访17个月

研究结果——PFS及OS

2.jpg3.jpg

•伊布替尼+BR显著改善IRC评估的PFS(NR vs. 13.3m),随访18个月时PFS分别为79%和24%(P<0.0001)

•两组中位OS均未达到,但安慰剂组90例(31%) 患者交叉进入伊布替尼组治疗

•在所有亚组中,伊布替尼治疗的PFS均显著改善

研究结果——ORR

4.jpg

•伊布替尼+BR组IRC评估的ORR显著更高(83% vs. 68%,P<0.0001)

•伊布替尼+BR组完全缓解率(CR/CRi)显著高于安慰剂+BR组(10% vs. 3%)

研究结果——MRD评估

5.jpg

•伊布替尼+BR组MRD阴性缓解率显著高于安慰剂+BR组(12.8% vs. 4.8%, P=0.0011)

•在CR/Cri患者中伊布替尼+BR组MRD阴性缓解率显著高于安慰剂+BR组(4.2% vs. 1.4%)

研究结果——安全性

•最常见的所有等级不良反应为中性粒细胞减少及恶心

•伊布替尼组77%(227/287) 患者及安慰剂组74%(212/287)患者报告了3-4级不良反应

•最常见的3-4级不良反应为中性粒细胞减少(伊布替尼组54% vs. 安慰剂组51%)和血小板减少 (两组均15%)

研究意义

•第一个评估伊布替尼联合苯达莫司汀和利妥昔单抗(BR)治疗rrCLL/SLL的Ⅲ期试验

•伊布替尼+BR与安慰剂+BR相比:

– 显著降低疾病进展或死亡风险80%

– 显著改善ORR

•伊布替尼+BR的安全性与单药的安全性一致

•结果证实伊布替尼联合BR治疗rrCLL/SLL优于目前的标准疗法

•HELIOS是第二个证实伊布替尼在rrCLL/SLL患者中可显著延缓复发的随机Ⅲ期研究

CSCO 2017: 黄慧强教授专访:浅谈套细胞淋巴瘤的治疗及BTK抑制剂的疗效

时光荏苒,岁月如梭,中国临床肿瘤学大会(CSCO)迎来了20年诞辰。在美丽的海滨城市厦门,9月27-30日,CSCO2017盛大开幕。本着“传承创新,携手同行”的宗旨,大会吸引来自国内外3万余位肿瘤领域的专家学者齐聚一堂,共襄盛会。CSCO历来重视血液肿瘤疾病的诊断和治疗,在此次盛会上,梅斯医学有幸采访了中山大学肿瘤医院黄慧强教授。黄慧强教授就套细胞淋巴瘤的治疗及BTK抑制剂的疗效等问题阐述了自己

伊布替尼适应症再次扩大:FDA批准伊布替尼成治疗慢性移植物抗宿主病(cGVHD)的药物

2017年8月2日,美国食品和药物管理局(FDA)扩大了Imbruvica(伊布替尼)的应用范围,批准用于治疗一项或多项治疗失败后的慢性移植物抗宿主病(cGVHD)的成年患者。此次批准伊布替尼是首个也是唯一获得FDA批准的治疗cGVHD成人患者药物。而cGVHD也是伊布替尼在肿瘤治疗领域之外的首个适应症。cGVHD是由于移植物的抗宿主反应而引起的一种免疫性疾病,是异基因造血干细胞移植的主要并发症和
