Biosimilars development demands rapid and reliable bioanalytical methods across preclinical and all phases of clinical trials to assess the similarity in the pharmacokinetic/ pharmacodynamic outcomes. Fast liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) has become the most widely employed bioanalytical technique in quantitative determination of small molecules. In this presentation, we discuss our strategies in extending the use of high-speed LC-MS/MS approaches to biosimilars assays under good laboratory practice (GLP)-compliant setting. The impact of sample preparation methods such as protein precipitation, solid-phase extraction and immuno-precipitation prior to chromatographic separation on assay sensitivity, selectivity, accuracy will be presented. The results obtained by the proposed method were compared with those obtained by ligand-binding assays.
