中心点:

Duvelisib,一种新型的PI3K-δ和γ的口服抑制剂,对于多种血液恶性肿瘤具有临床和药效学活性。

75mg BID被确定为MTD,25mg BID 用于2、3期期研究进行进一步评估。

摘要:

Duvelisib(IPI-145) ,是磷酸肌醇3-激酶(PI3K)-δ和PI3K-γ 的一种新型口服双重抑制剂,用于晚期血液恶性肿瘤的临床治疗。临床1期研究在210名晚期血液恶性肿瘤患者中评估IPI-145的最大耐受剂量(MTD)、药物代谢(PK)、药效动力学(PD)、疗效以及安全性。

在剂量递增阶段(31名患者),Duvelisib的剂量从8mg至100mg,确定其MTD为75mg BID。在扩展期(179名患者),惰性非霍奇金淋巴瘤(iNHL)、慢性淋巴细胞白血病(CLL)或T细胞淋巴瘤(TCL)患者,持续予以25mg或75mg的Duvelisib BID。

单剂量的Duvelisib可快速被吸收(1-2小时达到最大浓度),半衰期为5.2-10.9个小时。

PD结果显示,在CLL肿瘤细胞中,应用单剂量后,即可对p-AKT(S473)产生抑制,而第二个循环用药时,几乎可完全抑制CLL(ki-67)增殖。

在多个剂量水平和各种疾病亚型均可见临床反应,iNHL(31名患者)的总体缓解率58%,其中6例缓解反应(CRs);复发性/难治性CLL(55名患者) 56%,1例 CR;周围TCL(16名)50%,3例CR;皮肤性TCL(19名)总缓解率32%。缓解持续的中位时间约1.8个月。

84%的患者发生严重(3级及以上)副反应事件:中性粒细胞减少(32%)、丙氨酸转氨酶升高(20%)、天冬氨酸转氨酶升高(15%)、贫血和血小板减少(各14%)、腹泻(11%)和肺炎(10%)。

上述数据表明,Duvelisib或许可为恶性血液患者带来新的希望,但需要进一步开展临床2、3期试验进行深入研究。
