Uncover the crucial role of preclinical efficacy models in demonstrating a drug candidate's potential before human trials even begin. This episode explores both in vivo (animal) and in vitro (laboratory) models, highlighting the strengths and limitations of each approach. We delve into the complexities of model selection, considering factors like the disease being targeted and the drug's mechanism of action. We also discuss the concept of predictive power, which assesses how accurately a model's findings translate to humans, a crucial consideration in drug development.

Using real-world examples, including studies of Alzheimer's disease and new antibiotics, we illustrate the complexities of measuring efficacy in preclinical models. We explore the ethical considerations surrounding the use of animal models and the ongoing development of more human-relevant in vitro models. The influence of FDA and ICH guidelines on ensuring the quality, reliability, and ethical conduct of preclinical research will also be examined. Join us as we delve into the world of preclinical efficacy models and explore their vital role in the drug development journey.
