Preclinical testing in drug development typically includes which activities?

Preclinical testing focuses on evaluating how the compound affects biology and its safety in non-human systems. This involves in vitro experiments, like cell-based assays and receptor interactions to understand pharmacology and metabolic stability, and in vivo studies in animals to assess pharmacokinetics, pharmacodynamics, and potential toxicities. These studies help establish initial safety profiles, dosing ranges, and exposure limits before any testing in humans. Phase I trials involve humans, which is a later step. Regulatory submissions to authorities occur after substantial nonclinical and clinical data are gathered, not as part of preclinical testing itself. Marketing analysis is about commercialization and occurs well after safety and efficacy data have been generated. So the in vitro and in vivo studies to assess safety and biology are the components of preclinical testing.
