第61届美国血液学会(ASH)年会将于2019年12月7-10日在美国奥兰多隆重举行。该会议是血液病领域首屈一指的学术会议,汇集了全球血液病临床和研究科学家,共同探讨血液病领域的新技术、新进展。Jeff P. Sharman教授等报告的3期ELEVATE-TN研究(摘要号:31)结果显示,acalabrutinib单药或acalabrutinib+O治疗较O+Clb能明显改善初治慢性淋巴细胞白血病(TN CLL)的无进展生存(PFS),耐受性可接受,总生存(OS)改善尚需进一步确认。

研究背景

Acalabrutinib是一种高度选择性、共价不可逆的Brutton酪氨酸激酶抑制剂,对其他激酶的抑制作用小。研究已证实acalabrutinib单药或与obinutuzumab (O)联合治疗初治(TN)CLL,疗效持久。此处报告的是多中心、开放式、3期ELEVATE-TN研究(NCT02475681)的中期结果,该研究评价了acalabrutinib+O、Acalabrutinib单药和O+Clb治疗TN CLL患者的疗效和安全性。

研究方法

符合入组条件的TN CLL患者根据iwCLL标准需要治疗,患者年龄≥65岁或<65岁有并发情况(CIRS评分>6,肌酐清除率<70 mL/min)。患者1:1:1随机接受口服acalabrutinib (100 mg,2次/日)或acalabrutinib+O(1000mg 第 1, 2[100/900],8,15天,以后均为第1天,28天一周期,共6周期)或O+Clb(0.5 mg/kg 第1,15 天,28天一周期,共 6周期)。患者按照del(17p)、ECOG(≤1 和 2)以及区域分层。主要终点是独立审查委员会(IRC)评估的acalabrutinib+O与O+Clb治疗后的无进展生存(PFS)。关键次要终点包括IRC评估的acalabrutinib 和 O+Clb 治疗后的PFS,IRC评估的总的治疗反应率(ORR)、总生存(OS)和安全性,研究者评估的完全缓解(CR)/CR伴骨髓不完全恢复(CRi)患者的外周血或骨髓的微小残留病(MRD)评估。IRC证实的O+Clb治疗后疾病进展患者,允许交叉到acalabrutinib单药治疗。

研究结果

自2015年9月14日至2017年8月2日,535例患者随机分入acalabrutinib+O(n=179)、acalabrutinib(n=179)或O+Clb(n=177)组。中位年龄70岁(41~91岁),69%有高风险CLL IPI评分,12%有极高风险CLL IPI评分。中位随访28个月时,acalabrutinib+O较O+Clb显着延长PFS,分别为未达到[NR]和22.6个月(HR 0.10,95%CI 0.06-0.18,P<0.0001),减少疾病进展风险或死亡风险90%。Acalabrutinib(未达到)亦较O+Clb显着延长PFS(HR 0.20,95% CI 0.13–0.31,P<0.0001)。Acalabrutinib+O、acalabrutinib和O+Clb各组预估30个月的PFS率分别为90%、82%和34%。Acalabrutinib + O或acalabrutinib改善PFS在各亚组患者中一致,也包括del(17p)亚组(HR [95% CI]; 0.13 [0.04–0.46]; 0.20 [0.06–0.64])。

Acalabrutinib+O、acalabrutinib和O+Clb各组的中位OS均未达到(HR [95% CI];acalabrutinib+O和O+Clb,0.47 [0.21-1.06], P=0.0577;acalabrutinib和O+Clb,0.60 [0.28-1.27], P=0.1556)。各组预估30个月的OS率分别为95%、94%和90%,各组分别有5例(3%)、11例(6%)和55例(31%)接受了后续治疗,O+Clb组有45例患者(25%)交叉至acalabrutinib单药治疗组。

IRC评估的ORR,acalabutinib+O(94%;95%CI,89.3%-96.5%)高于O+Clb(79%;95%CI,71.9%-83.9%;P<0.0001),acalabrutinib单药组的ORR为85%。Acalabrutinib+O (13 %)组的CR率高于O+Clb (5%),acalabrutinib单药组有1例CR。

Acalabrutinib+O、acalabrutinib和O+Clb组的中位治疗持续时间分别为27.7个月(范围2.3~40.3)、27.7个月(范围0.3~40.2)以及5.6个月(范围0.9~7.4)。常见不良事件(AEs)在含acalabrutinib的二组间相似,acalabrutinib+O输注反应发生率(13%)低于O+Clb(40%)。Acalabrutinib+O组20例(11%)患者因AEs治疗中止,acalabrutinib组16例(9%),O+Clb 组25例(14%)停止治疗。随访超过2年,含acalabrutinib的二组患者中,79.3%仍在单药acalabrutinib治疗。

有意义的AEs(acalabrutinib+O或acalabrutinib与O+Clb)为心房颤动(任何级别:3%或4%与1%)、出血(任何级别/≥3级:43%/2%或39%/2%与12%/0%)和高血压(≥3级:3%或2%与3%)。

结论

Acalabrutinib+O和acalabrutinib单药治疗TN CLL较O+Clb能明显改善PFS,安全性可耐受。尽管O+Clb组疾病进展后交叉至acalabrutinib单药组,含acalabrutinib二组的OS仍呈改善趋势,当然需要更长的随访以进一步确认。
