JCO:依鲁替尼和Venetoclax连用,可治疗复发/难治性慢性淋巴细胞白血病

2019-07-14 海北 MedSci原创

最近,研究人员提出CLARITY试验,结合依鲁替尼和venetoclax,以根除可检测的CLL,目的是停止治疗。

慢性淋巴细胞白血病(CLL)的治疗已经通过抑制增殖(依鲁替尼)或重新激活细胞凋亡(venetoclax)的靶向疗法而发生了革命性的进展。两者都显着提高了CLL的存活率,并取代了许多患者的化学免疫疗法。

然而,单独使用时,它们很少导致可测量的残留病灶(MRD)的根除,并且通常需要无限期地给药或直至进展。

最近,研究人员提出CLARITY试验,结合依鲁替尼和venetoclax,以根除可检测的CLL,目的是停止治疗。

CLARITY是一项II期临床试验,将依鲁替尼与venetoclax联合用于复发或难治性CLL患者。主要终点是联合治疗12个月后根除MRD。关键的次要终点是国际研讨会对CLL标准,安全性,无进展和总体生存的反应。

结果显示,在依鲁替尼和venetoclax共同治疗12个月后的53例患者中,在28例(53%)患者的血液中和19例患者(36%)的骨髓中实现了MRD阴性(10,000个白细胞中少于一个CLL细胞)。 47名患者(89%)做出了回应,27名患者(51%)完全缓解。

中位随访21.1个月后,一名患者有进展,所有患者均存活。观察到单例生化肿瘤溶解综合征。其他不良反应轻微和/或易于控制,最常见的不良反应是中性粒细胞减少症或肠道事件。

因此,对于复发或难治性CLL患者,依鲁替尼加venetoclax的组合耐受性良好。根除MRD的比率很高,导致一些患者停止治疗。复发和难治性CLL的无进展和总生存率是令人鼓舞的。
