TDM of Biologics Committee

Committee Purpose

  • To develop guidelines for the use of TDM of biologics;
  • To encourage the use of TDM of biologics with the aim of optimizing clinical drug use and outcomes;
  • To promote development of PK and PKPD models that can be used for dose adjustment in clinical practice;
  • To provide knowledge of PK and the PK-response interactions;
  • To promote best practice in relation to laboratory analysis of biologics;
  • To enhance collaboration between groups working in the field and disseminate research in this area;
  • To provide information on the measurement and clinical relevance of antibodies to biologics;
  • To focus on harmonization and standardization of assays for TDM.

Committee Initiatives & Activities

2021 To perform an international comparative study across assays every 5 years.
To continue contributions for Compass.
To suggest some names of new members (TDM of Biologics in Oncology) or propose a collaboration with the TDM in Oncology Scientific Committee and the Pharmacometrics Committee.
To update website.
To submit proposals for workshops and symposia for the next IATDMCT Congresses.
To seek opportunities for affiliation with other societies.
To re-organize educational activities (workshops) cancelled in 2020:
  • University of Barcelona and Hospital Universitari de Bellvitge. IDIBELL: two workshops were organized but cancelled due to the pandemic in 2020:
    • I Jornada de Actualización Práctica en Monitorizacion Farmacocinética. Situacion actual y perspectivas de futuro (cancelled twice-March and Nov 2020). Location: Hospital Universitari de Bellvitge.
    • Population modeling with Pmetrics and dose optimization with BestDose web-based tool. Location: Bellvitge Health Sciences Campus. School of Medicine. Barcelona (july 2020)
