| PK/ADME Studies |
- PK/TK sample analysis (LC-MS/MS)
- property characterization (F, T1/2, Cmax, Tmax, CL, Vss, AUC), typically in mouse, rat, dog and monkey
- Dose proportionality
- Assessment of hepatic first pass effect and biliary excretion
- PK/PD relationship
- Drug permeability assay (CaCO2)
- Metabolic stability (microsomes, S9 and hepatocytes)
- CYP inhibition (IC50, Ki) for DDI
- CYP reaction phenotyping
- Plasma protein binding assays
- Plasma satbility evaluation
|
| Preliminary Toxicity Assessment |
- Rising dose 7-day and 14-day tox studies (mice / rats)
- Enzyme assays
- LD50 and MTD study
- Dermal toxicity (rabbits)
- Blood chemistry and histology
|
| In vitro Studies |
- Enzyme assays
- Cell culture and assays
- Gene expression analysis
