通过pH介导的药物相互作用 (DDI) 是常见的,特别是对于弱基. 生物预测方法和基于生理学的生物制药建模 (PBBM) 可以准确评估降酸剂 (ARA) -DDI,减少开发负担,并可能放弃临床研究.
科学领域:
- 药理动力学和药物新陈代谢
- 药物开发和监管科学 药物开发和监管科学
背景情况:
- 通过pH介导的药物相互作用 (DDI) 是普遍存在的,特别是对于具有pH依赖溶解度的弱基化合物.
- 美国FDA已经发布了评估pH介导DDI的指南,但在学术界和工业界缺乏标准化测试实践.
研究的目的:
- 审查和提出改进的策略,以评估和减轻pH介导的药物相互作用 (DDI).
- 为生物相关溶解测试,临床前和临床研究要求以及用于降酸剂 (ARA) -DDI评估的生理基础生物制药建模 (PBBM) 提供全面的概述.
主要方法:
- 生物相关溶解测试方法.
- 用于DDI评估的临床前和临床研究设计.
- 基于生理学的生物制药建模 (PBBM) 方法.
- 开发一个改进的决策树,用于pH介导的DDI评估.
主要成果:
- 生物预测方法和PBBM方法可以准确预测ARA-DDI.
- 这些建模方法可以降低药物开发负担,为临床试验设计提供信息,并可能导致放弃临床研究.
- 配方策略和仔细的临床设计可以减轻pH介导的DDI.
结论:
- 使用生物预测和PBBM方法准确预测ARA-DDI,在药物开发中提供了显著的优势.
- 缓解策略,包括配方和临床设计,可以减少对广泛临床研究和标签限制的需求.
