Abstract

We conducted a phase I study using midostaurin (25 or 50 mg orally twice daily), all-trans retinoic acid (ATRA) and CLAG chemotherapy to target multiple pathways in relapsed/refractory AML. 10 patients received the combination and no dose-limiting toxicities were observed. Two patients (22 %) achieved complete remission and 1 patient (11 %) achieved complete remission with incomplete count recovery. Pharmacokinetic data showed that the 25 mg dosing of midostaurin achieved therapeutic levels with no significant interaction between midostaurin and ATRA. With evidence of activity of ATRA in NPM1-mutated AML and midostaurin in FLT3-ITD AML, this combination warrants further investigation.

摘要

我们开展了一项I期研究,使用米哚妥林(口服25或50毫克,每日两次)、全反式维甲酸(ATRA)和CLAG化疗来靶向复发/难治性急性髓系白血病(AML)的多种信号通路。10名患者接受了联合治疗,未观察到剂量限制性毒性。2名患者(22%)实现完全缓解,1名患者(11%)实现完全缓解但血细胞计数未完全恢复。药代动力学数据显示,25毫克剂量的米哚妥林达到了治疗水平,且米哚妥林与ATRA之间无显著相互作用。鉴于ATRA在NPM1突变型AML中以及米哚妥林在FLT3-ITD AML中均有活性证据,该联合治疗值得进一步研究。
