Lancet Oncol:依鲁替尼-利妥昔单抗诱导治疗可减少套细胞淋巴瘤的化疗疗程

2022-02-02 Nebula MedSci原创

依鲁替尼-利妥昔单抗诱导方案用作年轻套细胞淋巴瘤患者的一线治疗有效且安全

鉴于预先使用这些依鲁替尼和利妥昔单抗靶向治疗可以使淋巴瘤患者在不化疗的情况下就得到缓解,而且还可以将8个疗程的巩固治疗缩减到4个,因此,依鲁替尼和利妥昔单抗诱导治疗可以为患者减少化疗暴露的机会。

本研究目的是在既往未治疗过的套细胞淋巴瘤患者中评估依鲁替尼-利妥昔单抗诱导治疗继以4个疗程的化学免疫治疗(利妥昔单抗+超分馏环磷酰胺、长春新碱、阿霉素和地塞米松[R-HCVAD;A部分]或甲氨喋呤-阿糖胞苷[B部分])的安全性和疗效。

这是一项单中心、单臂的2期临床试验,招募了不超过65岁的血清胆红素<1.5mg/dL、肌酐清除率≥30 mL/min、ECOG表现状态0-2分以及心脏射血分数≥50%的套细胞淋巴瘤患者,予以12个疗程的依鲁替尼+利妥昔单抗治疗(A部分:每日口服依鲁替尼 560mg,静滴利妥昔单抗 375mg/m2[前4周 1次/周,第3-12周仅第1天给药)。患者很快获得了完全缓解。主要终点是A部分后的总缓解率。

所有患者的5年无进展生存期和总生存期

2015年6月12日至2018年12月6日共招募了131位患者,中位年龄为65岁(IQR 49-60)。58位(5%)患者有高Ki-67(≥30%)。129位(98%)患者获得了缓解。

A部分最常见的3-4级副作用有淋巴细胞减少症(14%)、皮疹(12%)、血小板减少症(9%)、感染(8%)和疲劳(8%);B部分最常见的3-4级副作用有淋巴细胞减少症(30%)和中性粒细胞减少症(20%)。一位患者在研究期间死亡,但经鉴定与治疗无关。

综上,依鲁替尼-利妥昔单抗诱导方案用作年轻套细胞淋巴瘤患者的一线治疗有效且安全。该方案可缩减化疗疗程,从而减少与化疗相关的不良事件。
