Preclinical Research




During the preclinical stage, studies in animal models are combined with cellular and biochemical assays to understand the effects of lead drug candidates and provide detailed reporting on the pharmacological profile, acute toxicity in at least two animal species, and short-term toxicity studies. Early dosage studies are also performed to guide the implementation of subsequent clinical phases. Show more

Testing includes the pharmacology of absorption, distribution, metabolism, and excretion (ADME), metabolic stability, pharmacokinetics, immunogenicity/ADA, biomarker analysis, and the mutagenicity, reproductive effects, and in vitro and in vivo toxicity of candidates and their metabolites. Data from this phase are used to determine whether to proceed to human testing, and the no observable adverse effect levels (NOAELs) are used to guide starting dosages in clinical trials. Show less

Additional Methodolgies and Research Within Drug Discovery and Development

Biomarker Discovery

Biomarker Discovery
The use of biomarkers across drug discovery and development and into the clinic is key to enabling close monitoring of a drug candidate’s effects. Biomarkers can range from specific molecules such as a protein, a gene sequence, or expressed RNA to physiological parameters such as blood pressure. Biomarkers may be detected in a specific location or tissue or in plasma and other bodily fluids.

Biochemical and Cellular Assays

Biochemical and Cellular Assays
Biochemical and cellular pharmacology teams develop and validate assays to support research across drug discovery and development. These assays range from discovery approaches with high sample throughput to high-content analysis to gain an understanding of biological response both in vitro and in vivo.
