PEGylated drug preclinical / clinical bioanalytical studies NMR or LC-MSMS methods for biologics or small molecules
PEGylated drug preclinical or clinical bioanalysis requires robust and innovative methods. Covalent attachment of one or more poly(ethylene glycol) (PEG) chains to a therapeutic drug, also known as PEGylation, has been found to be effective in improving a drug’s pharmacokinetic (PK) profile with potentially an extended half-life of the drug in the body.
Conventional bioanalytical techniques can be challenged during PEGylated drug studies including PEG clearance studies due to increases in the molecular size of the drug and complexity following PEGylation and currently there is no general consensus on the most appropriate analytical approach for PK studies of PEGylated drugs. Additionally, the slow clearance of large PEGylated molecules from the body has raised concerns about potential PEG accumulation in tissues following chronic administration.
Our Good Clinical Practice (GCP) or Good Laboratory Practice (GLP) compliant laboratories develop and validate innovative bioanalytical approaches for PEGylated species, such as the use of nuclear magnetic resonance spectroscopy (NMR), providing robust bioanalytical methods to quantify PEGylated compounds across a diverse set of biological matrices and species. Our scientists are adept at developing and validating bioanalytical methods which are suitable for supporting both preclinical and clinical bioanalytical studies whilst meeting the requirements of Bioanalytical Method Validation guidelines.
