联合使用venetoclax和ibrutinib是治疗高风险和老年CLL患者的有效方案

Ibrutinib是Brutton的酪氨酸激酶抑制剂, venetoclax是B细胞淋巴瘤2蛋白抑制剂,这2个药物均已被批准用于慢性淋巴细胞白血病(CLL)患者,临床前研究表明二者组合有潜在的协同作用。

研究人员进行了一项关于ibrutinib和venetoclax联合治疗的II期研究,先前未治疗的高风险和老年CLL患者参与,患者至少具有以下特征之一:染色体17p缺失,突变TP53,染色体11q缺失,未突变的IGHV或65岁疑似年龄。患者接受ibrutinib单一疗法(每天420毫克,每天一次)3个周期,然后加入venetoclax(每周一次剂量递增至400毫克,每日一次)。,联合治疗进行24个周期。 根据2008年慢性淋巴细胞白血病国际研讨会标准进行反应评估,通过骨髓中的多色流式细胞术评估最小残留疾病。

80名患者,中位年龄65岁,30%的患者年龄在70岁以上。92%的患者存在未突变的IGHV、TP 53畸变或染色体11q缺失。联合治疗后,随着时间的推移,完全缓解和有无法发现的微小疾病残留缓解患者的比例都在增加。经12个周期的联合治疗,88%的患者有完全缓解或完全缓解,61%的患者有无法检测到的微小疾病残留的缓解。3例患者发生肿瘤溶解综合征。

研究认为,联合使用venetoclax和ibrutinib是治疗高风险和老年CLL患者的有效方案。
