Therapeutic drug monitoring (TDM) involves measuring and interpreting drug concentrations in biological fluids to adjust drug dosages. In onco-hematology, TDM guidelines for oral molecular targeted therapies (oMTTs) are varied. This study evaluates a quantitative approach with a score to predict the clinical usefulness of TDM for oMTTs.

Article Synopsis
  • Belimumab is a monoclonal antibody effective in treating systemic lupus erythematosus (SLE), available in both intravenous and subcutaneous forms, prompting a study to develop a reliable method for measuring its levels in human serum.
  • The study utilized a technique called nano-surface and molecular-orientation limited (nSMOL) proteolysis combined with liquid chromatography-tandem mass spectrometry (LC-MS/MS) for quantification, achieving a total assay time of 10 minutes with high accuracy and precision.
  • Results revealed that belimumab concentrations were significantly higher in patients receiving subcutaneous administration compared to intravenous, and the developed method can enhance future research on belimumab's effectiveness and safety in SLE treatment

Introduction: Mycophenolate mofetil (MMF), a pro-drug of mycophenolic acid (MPA), has become a major therapeutic option in juvenile systemic lupus erythematosus (jSLE). Monitoring MPA exposure using area under curve (AUC) has proved its value to increase efficacy and safety in solid organ transplantation both in children and adults, but additional data are required in patients with autoimmune diseases. In order to facilitate MMF therapeutic drug monitoring (TDM) in children, Bayesian estimators (BE) of MPA AUC using limited sampling strategies (LSS) have been developed.
