摘要

背景:伊伯多米德是一种新型强效脑龙调节剂(CELMoD®),目前正处于治疗血液恶性肿瘤的临床开发阶段。为了确定伊伯多米德的生物转化和排泄途径,我们进行了一项人体质量平衡研究:方法:6 名健康受试者在服用单剂量放射性标记的 [14C]-iberdomide (1 毫克)后。收集血液、尿液和粪便样本,进行药代动力学、质量平衡和临床实验室评估:结果表明,健康受试者对单次口服 1 毫克 iberdomide 的耐受性普遍良好。人体尿液中[14C]-iberdomide 衍生放射性的回收率为 45.9%,粪便中的回收率为 42.6%。根据暴露量(浓度-时间曲线下面积 [AUC0-24]),伊伯多米和 M12(代谢物)分别约占循环总放射性(TRA)暴露量的 59% 和 14%。在88.5%的TRA排泄量中,约27%以未改变的伊伯多米德形式排泄,62%以代谢物形式排泄,尿液(16%)和粪便(11%)中的代谢物排泄量相似:结论:伊博多肽在人体中的生物转化包括吗啉基的多重氧化、母体和氧化代谢物的戊二酰亚胺环水解以及这些途径的组合。伊伯多米德是人体血浆中的主要成分,代谢物 M12 是最主要的循环代谢物。在排泄物中,尿液和粪便中也发现了类似的伊伯多米德衍生放射性:试验注册号:NCT03294603。

A Phase I, Open-Label, Mass Balance Study of [<sup>14</sup>C]-Iberdomide in Healthy Subjects.

A Phase I, Open-Label, Mass Balance Study of [14C]-Iberdomide in Healthy Subjects.

Background: Iberdomide is a novel potent cereblon modulator (CELMoD®) agent, which is currently under clinical development for hematological malignancies. A human mass balance study was conducted to characterize the biotransformation and excretion pathways of iberdomide.

Method: After a single dose of radiolabelled [14C]-iberdomide (1 mg) in six healthy subjects. Blood, urine, and fecal samples were collected for pharmacokinetics, mass balance, and clinical laboratory assessments.

Results: Results showed that a single oral dose of 1 mg iberdomide was generally well tolerated in healthy subjects. The recovery of [14C]-iberdomide-derived radioactivity in humans was 45.9% in urine and 42.6% in feces. Based on exposure (area under the concentration-time curve [AUC0-24]), iberdomide and M12 (metabolites) accounted for approximately 59% and 14% of circulating total radioactivity (TRA) exposure, respectively. Of the 88.5% TRA excreted, approximately 27% was excreted as unchanged iberdomide and 62% as metabolites, with similar amounts of excreted metabolites in the urine (16%) and feces (11%).

Conclusion: Biotransformation of iberdomide in humans included multiple oxidations of the morpholino moiety as well as glutarimide ring hydrolysis of parent and oxidized metabolites and a combination of these pathways. Iberdomide was the predominant component in human plasma, with metabolite M12 being the most prominent circulating metabolite. In excreta, similar iberdomide-derived radioactivity was found in urine and feces.
