自体造血干细胞移植后高剂量化疗对是复发性或原发性难治性霍奇金淋巴瘤的标准治疗。大约50%的患者在自体造血干细胞移植后痊愈;然而,大多数不利的危险因素患者移植后病情会进一步发展。我们的目的是评估brentuximab vedotin是否改善自体干细胞移植术后。

方法 我们在北美和欧洲78个地点做这项随机,双盲,安慰剂对照的3期临床试验。不利的风险复发性或原发性难治性经典霍奇金淋巴瘤患者自体造血干细胞移植患者被随机分配,由计算机生成的随机数序列的固定块随机化,接受16个周期1•8 mg/kg 的brentuximab vedotin或安慰剂静脉注射,每3周一次,移植后30-45天开始。挽救化疗完成后通过最好的临床反应进行了随机分层(完全缓解和部分响应和稳定的疾病),原发性难治性霍奇金淋巴瘤和一线治疗完成后不到12个月复发,治疗全部完成后不到超过12个月复发性疾病。患者和研究者均不知晓治疗分配情况。主要终点是无进展生存期的独立审查,定义为从随机化的肿瘤进展或死亡的第一个文件开始。采用意向治疗分析。

发现 在2010年4月6日到2012年9月21日之间,我们随机分配329例患者为brentuximab vedotin组(n = 165)或安慰剂组(n = 164)。与安慰剂组相比, brentuximab vedotin组患者通过独立审查的无进展生存期有了显著改善(危险比[HR] 0•57,95%CI 0•40-0•81; P = 0•0013)。由独立的审查得到的中位无进展生存期brentuximab vedotin组患者是42•9个月(95%CI 30•4-42•9),安慰剂组患者为24•1个月(11•5—无法估量的)。我们记录了brentuximab vedotin整个分组整合一致的利益(HR <1)。该brentuximab vedotin组中最常见的不良反应是外周感觉神经病变(94 [56%]的167例和安慰剂组25 [16%]的160例,)和中性粒细胞减少(58 [35%]比19 [12%]例)。在分析时期内,brentuximab vedotin组167例患者有28例(17%)已经死亡,安慰剂组160例中有25例(16%)死亡。

解释 早期的自体干细胞移植后与brentuximab vedotin的组合改善无进展生存患者的霍奇金淋巴瘤的移植后复发或进展危险因素。这种治疗为接受自体干细胞移植的患者提供了重要的治疗选择。
