Validation of a method for the determination of Aderamastat (FP-025) in K2EDTA human plasma by LC-MS/MS

Aderamastat (FP-025) is a small molecule, selective matrix metalloproteinase (MMP)-12 inhibitor, under development for respiratory conditions which may include chronic inflammatory airway diseases and pulmonary fibrosis. To support evaluation of the pharmacokinetic parameters of Aderamastat in humans, we developed and validated a high-performance liquid chromatography tandem mass spectrometry (LC-MS/MS) analytical method for the quantification of Aderamastat in human plasma. This assay was validated in compliance with the Food and Drug Administration (FDA) Good Laboratory Practice Regulations (GLP) and European Medicines Agency (EMA) guidelines. K₂EDTA human plasma samples were spiked with internal standard, processed by liquid-liquid extraction, and analyzed using reversed-phase HPLC with Turbo Ion Spray® MS/MS detection. Separation was done using a chromatographic gradient on 5 µm C6-Phenyl 110 Å, 50*2 mm analytical column at a temperature of 35 °C. The LC-MS/MS bioanalytical method, developed by QPS Taiwan to determine the concentration of Aderamastat in K₂EDTA human plasma, was successfully validated with respect to linearity, sensitivity, accuracy, precision, dilution, selectivity, hemolyzed plasma, lipemic plasma, batch size, recovery, matrix effect, and carry-over. These data indicate that the method for determination of Aderamastat concentrations in human K₂EDTA plasma can be used in pharmacokinetics studies and subsequent clinical trials with Aderamastat. Authors declare that, this novel data is not published and not under consideration for publication by another journal than this journal. All data will be made available on request.
