Radiolabel ADME

A well-conceived and executed preclinical and clinical radiolabelled ADME program will provide you with a detailed assessment of the total fate (mass balance, route and rate of excretion, tissue distribution, metabolic pathways, and identity and quantity of metabolites) of your drug candidate to support regulatory submissions.

Preclinical Radiolabelled ADME studies:
  • Mass Balance/Routes of Excretion
  • Placental/Milk Transfer
  • Quantitative Whole-Body Autoradiography (QWBA)
  • Microautoradiography (MARG)
  • Plasma Protein Binding; RBC/Plasma Distribution
  • Assessment of Covalent Binding
  • InvitorsSpecies Comparison of Metabolism
  • Metabolic Reaction Phenotyping
  • Metabolite Profiling, Idntification& Radioquantification
Human Radiolabelled ADME studies:
  • Consultion and Preparation of Clinical Study Protocol; including determination of human radiation dosimetry estimates on the basis of recommendtions by MIRD, ICRP and/or the Sponsor
  • Ethnics Committe & Competent Authority Submission
  • Preparation and Release of Radiolabelled IMP According to GMP Annex 13 by a Licensed Radio-pharmacy; including homegeneity and assessment of radio-Purity of the IMP in formulation by HPLC-radio flow-through detection prior to dispensing
  • Drug Administration of Radiolabelled IMP by a Degnated and Radio-licensed Research Physician
  • Flawless Execution of Study According to Protocol
  • Collection, Processing, and Analysis of Radioactive Human Blood, Plasma, and Excreta (urine, feces, and expired air.)
  • Metabolite Profiling, Identification & Radio quantification
  • Preparation and Submission of an Integrated Clinical Study Report(CSR)
