Background & Purpose of the Committee

  • To provide evidence-based recommendations for TDM of immunosuppressive agents.
  • To promote the knowledge and understanding of immunosuppressive drug analysis and interpretation of results.
  • To enhance communication between scientists and physicians of all disciplines involved in TDM of immunosuppressive drugs.
  • To encourage the effective application of TDM in transplant medicine, with the aim of optimizing clinical drug use and maximizing the clinical and economic benefits.

Activities Planned/Committee Initiatives Currently in Progress

  • Preparation of a new consensus paper; entitled Mycophenolate Personalized Therapy: Consensus Report by the International Association of Therapeutic Drug Monitoring and Clinical Toxicology; in progress.
  • A satellite symposium, Update on mycophenolate, was suggested, accepted and planned for the IATDMCT-meeting in Banff 2020. This symposium may now be suggested for the next opportunity, e.g. Rome 2021.
  • To establish a course in TDM related to transplantation. This will be a course to follow online. The initiative is by D.J.A.R Moes and supported by current chair and vice chair of the ISD-SC. This project is in an early phase, and we are investigating options like integration into an already established course or to establish a new, separate course on this topic. A group of members will be recruited to develop the course. (Directors of education in the IATDMCT are informed.)
  • The online forum for the IATDMCT has been discontinued. The ISD-SC is a relatively large group and some kind of forum may be useful to facilitate communication. The setup of a dedicated forum for this committee is under consideration.
