Clin Cancer Res:随访8年!依鲁替尼治疗CLL/SLL长期有效!

一项Ib/II期PCYC-1102研究(NCT01105247) 证明了Bruton酪氨酸激酶(BTK)抑制剂依鲁替尼(1/日)在慢性淋巴细胞白血病/小淋巴细胞淋巴瘤(CLL/SLL)中的安全性和有效

一项Ib/II期PCYC-1102研究(NCT01105247) 证明了Bruton酪氨酸激酶(BTK)抑制剂依鲁替尼(1/日)在慢性淋巴细胞白血病/小淋巴细胞淋巴瘤(CLL/SLL)中的安全性和有效性。研究人员将该试验的随访时间延长至8年,这是迄今为止依鲁替尼单药,或是所有BTK抑制剂,最长的随访时间,该随访结果于近日发表在《Clinical Cancer Research》上。

PCYC-1102研究及其扩展研究PCYC-1103 (NCT01109069)纳入接受依鲁替尼单药作为一线治疗的或复发/难治性CLL/SLL患者。

总体缓解率达到89%,以依鲁替尼为一线治疗的或复发/难治性CLL/SLL患者的总体缓解率相近(87% vs 89%;完全缓解率:35% vs 10%)。以依鲁替尼为一线治疗的患者的预计7年无进展生存(PFS)率为83%,而复发/难治性患者的只有34%。41位患者发生CLL进展(11位伴随Richter转型)。

以依鲁替尼为一线治疗的患者的中位PFS未达到。在复发/难治性CLL/SLL患者中,总体中位PFS为52个月,携带染色体17p缺失、11q缺失、12-三体或13q缺失以及无这些染色体异常的患者的中位PFS分别是26个月、51个月、未达到和88个月。一线治疗和复发/难治性背景患者的预计7年总体存活率分别是84%和55%。

发生在>15%患者的≥3不良反应(AE)有高血压(28%)、肺炎(24%)和中性粒细胞减少(18%)。除了高血压,≥3级AE一般随时间的推移而减少。导致2位及以上患者终止治疗的AE仅见于复发/难治性患者(败血症、腹泻、硬膜下血肿和Richter转型)

总结:经过长达8年的随访,采用依鲁替尼单药治疗一线或复发/难治性CLL/SLL(包括高危CLL/SLL),可获得持久的缓解和长期的耐受性。
