Quantitative Systems Pharmacology
The FDA is shifting away from relying solely on animal biology in drug development, towards a more complex approach using Quantitative Systems Pharmacology (QSP) and artificial intelligence. QSP is a mathematical framework that simulates the behavior of the human body, allowing for more accurate predictions of drug safety and efficacy. This approach has the potential to reduce and replace animal models in drug development.

Key Concepts
Quantitative Systems Pharmacology (QSP)
- QSP is a mathematical framework that simulates the behavior of the human body
- QSP is used to predict drug safety and efficacy
- QSP is particularly useful for modeling complex biologics and immunotherapies
New Approach Methodologies (NAMs)
- NAMs provide physical human-relevant biology to complement QSP
- NAMs include organs on a chip and other microphysiological systems
- NAMs can be used to test drug safety and efficacy in a more human-relevant way
Artificial Intelligence (AI)
- AI is being used to speed up QSP simulations
- AI is being used to improve pattern recognition in QSP models
- AI is being used to optimize experiments and reduce uncertainty in QSP models
Regulatory Framework
- The FDA is demanding a rigorous risk-based standard for QSP models
- The FDA is emphasizing strict controls, including pre-specified validation plans and blinded compound challenges
