Following a US National Academy of Sciences report in 2007 entitled "Toxicity Testing of the 21st Century: a Vision and a Strategy," significant advances within translational drug safety sciences promise to revolutionize drug discovery and development. The purpose of this review is to outline why investigative safety science is a competitive advantage for the pharmaceutical industry.
The article discusses the essential goals for modern investigative toxicologists including: cross-species target biology; molecular pathways of toxicity; and development of predictive tools, models and biomarkers that allow discovery researchers and clinicians to anticipate safety problems and plan ways to address them, earlier than ever before. Furthermore, the article emphasizes the importance of investigating unanticipated clinical safety signals through a combination of mechanistic preclinical studies and/or molecular characterization of clinical samples from affected organs.
The traditional boundaries between pharma industry teams focusing on safety/efficacy and preclinical/clinical development are rapidly disappearing in favor of translational safety science-centric organizations with a vision of bringing more effective medicines forward safely and quickly. Comparative biology and mechanistic toxicology approaches facilitate: i) identifying translational safety biomarkers; ii) identifying new drug targets/indications; and iii) mitigating off-target toxicities. These value-adding safety science contributions will change traditional toxicologists from side-effect identifiers to drug development enablers.
2007 年美国国家科学院发表了一份题为“21 世纪的毒性测试:愿景与战略”的报告,自此之后,转化药物安全科学领域取得了重大进展,有望彻底革新药物研发。本文旨在概述为何探索性安全科学是制药行业的竞争优势。
本文讨论了现代探索性毒理学家的基本目标,包括:跨物种靶标生物学;毒性的分子途径;以及开发预测工具、模型和生物标志物,使发现研究人员和临床医生能够比以往任何时候都更早地预测安全性问题并计划解决方法。此外,本文强调了通过结合机制性临床前研究和/或受影响器官的临床样本的分子特征来探索意外的临床安全性信号的重要性。
专注于安全性/疗效和临床前/临床开发的制药行业团队之间的传统界限正在迅速消失,取而代之的是以转化安全科学为中心的组织,其愿景是安全、快速地推出更有效的药物。比较生物学和机制毒理学方法有助于:i)确定转化安全性生物标志物;ii)确定新的药物靶标/适应症;和 iii)减轻非靶标毒性。这些增加价值的安全科学贡献将把传统毒理学家从副作用识别者转变为药物开发推动者。
