Pharmacokinetic and Toxicokinetic Bioanalysis
Pharmacokinetic (PK) bioanalysis is a critical aspect of drug development. PK studies may be exploratory in nature or more extensive and formal. Understanding the bioavailability, exposure, half-life, clearance and metabolism of a drug may be the difference between success and failure in the clinic. Pacific BioLabs provides in vivo dosing and sampling in multiple species, and can coordinate PK studies to perform all aspects including in vivo dosing and sample collection, PK bioanalysis, and preparation of PK data.
PK Bioanalysis at Pacific BioLabs
Pacific BioLabs’ analytical and bioanalytical laboratory contains GLP-compliant instrumentation, including multiple LC/MS/MS systems as well as ELISA platforms to provide sensitive, high throughput measurement of drug concentration in a variety of matrices.
PBL has great expertise in the development of analytical methods and can quickly perform bioanalytical method development and validation of sensitive, accurate and robust PK assays. PBL’s chemists have experience working with plasma, serum, urine, CSF, and other tissues, and will optimize the extraction conditions to provide a reproducible and robust method. PBL has numerous temperature controlled and monitored chambers to properly store sensitive samples prior to analysis. Method validations typically include an assessment of pre-preparative stability to demonstrate that drug residues in tissues are stable over the course of the study.
Pharmacokinetic Studies Utilizing ICP-MS
For compounds containing metals, ICP-MS may be used to perform PK bioanalysis. ICP-MS has the benefits of low detection levels (as low as 1 ppb) and good specificity. Many new drugs are metals-based where the drug’s activity is dependent on the bioavailability of the metal. So whether your metal-based drug reaches its target through the blood or being absorbed into the skin, ICP-MS may be an excellent choice to measure the kinetics of your drug.
Other drugs may contain metals in their formulation: often these are carried over from the synthetic production of the drug. Copper, platinum, palladium, and cobalt are just a few examples of metals that are commonly detected in drug formulations. Whether you need to determine the level of a specific metal in your formulation, screen your drug for multiple metal residues, or measure the tissue levels for a metal following dosing, Pacific BioLabs can develop and perform the ICP-MS method to meet your needs.
