Abstract
|
|
|
|
Modern biologics are biotechnology-derived therapeutics, including recombinant therapeutic proteins like monoclonal antibodies, cytokines and tissue growth factors. Although the pharmacokinetics of therapeutic biologics should be evaluated based on the same general principles as small molecules, careful considerations should be given to bioanalytics and pharmacokinetics when designing pharmacokinetic studies of biologics during their drug development, due to their different physicochemical properties compared with small molecules. The aim of this study was to develop a draft guidance on pharmacokinetic studies of therapeutic biologics in clinical studies. All the elements outlined in the current Food and Drug Administration (FDA), European Medicinal Agency (EMEA), and International Conference on Harmonisation (ICH) guidelines and regulations, and the related literatures previously published were searched and evaluated. In this draft guidance, the specific problems related to the pharmacokinetics of therapeutic biologics that need special consideration during drug development process were addressed, and differences in pharmacokinetic characteristics between biologics and small molecules affecting the content of the development programme were presented.
