“Polyethylene Glycol (PEG) Quantitation in Biofluids supporting Drug Discovery”


Conjugation of macromolecular drugs to polyethylene glycol (PEG) improves their therapeutic potential by enhancing the half-life. As a substantial component of the drug, it is necessary to measure the pharmacokinetic (PK) characteristics of PEG in vivo. A quantitative NMR-based method was developed and applied to measuring 40 kDa PEG in serum, enabling determination of PK parameters in preclinical species. Observed half-life was found to be consistent with 125Iodine-labeled PEG methods. Moreover, urinary quantitation of 20kDa PEG  was used to investigate side effects of a pegylated biologic. NMR spectroscopy was shown to be a convenient and reliable alternative to follow pharmacokinetics of PEG in various biofluids.
