一个IRE1-α抑制剂ORIN1001的第一个群体药理动力学 (PopPK) 模型确定了总胆红素和瘦体重作为影响药物暴露的关键因素. 这种模型有助于ORIN1001在未来的癌症治疗开发.
科学领域:
- 药理学 药理学是指药理学的学科.
- 在瘤学瘤学.
- 临床药理学 临床药理学
背景情况:
- ORIN1001是一种新的口服IRE1-α内啡核酶抑制剂,向XBP1激活.
- 它正在临床研究中,用于抑制癌症生长,并加强化疗或向治疗.
研究的目的:
- 为ORIN1001.1.开发第一个人群药理动力学 (PopPK) 模型.
- 描述ORIN1001的药理动力学 (PK) 并确定影响的共变量.
- 支持正在进行的ORIN1001.1.的临床开发.
主要方法:
- 采用了一种非线性混合效应模型,使用了来自中国高级固体瘤患者的I期临床试验 (NCT05154201) 的数据.
- 共变量分析采用了一个逐步选过程.
- 模型验证包括良性合适图,非参数引导,视觉预测检查和规范预测分布错误.
主要成果:
- 一个具有第一阶吸收和排泄的两模型最好地描述了ORIN1001 PK.
- 总胆红素 (TBIL) 和瘦肉体重 (LBW) 被确定为影响ORIN1001口服清除 (CL/F) 的显著共变量.
- 模拟证实了TBIL和LBW对稳定状态ORIN1001暴露的临床显著影响.
结论:
- 为ORIN1001成功建立了第一个PopPK模型.
- TBIL和LBW是ORIN1001暴露的重要共变量,为潜在的剂量调整提供信息.
- 需要在较大的群体中进一步验证,以确认剂量调整的必要性.
