Event

Human microtracer studies in drug development: How, when and why

Fletcher Hotel Leiden • 21 Apr 2022

Ad Roffel of ICON and Wouter Vaes of TNO cordially invite you to join our Microtracer Symposium on April 21st. The symposium will be held in the Fletcher Hotel Leiden, The Netherlands. 

Purpose of the symposium

We welcome interested pharma companies that want to know more about, or that are considering the use of microtracers in drug development programmes.

Both the clinic of ICON as well as the AMS laboratory of TNO have conducted a large number of microtracer studies during the last 10 years. The increased interest in microtracer studies triggered ICON and TNO to organise this one-day symposium to share experiences, to discuss hurdles and challenges.





Programme and speakers

(Please note: registration for this event is closed)

The symposium starts at 9 a.m. and ends at 5 p.m. with drinks and bites.

The programme consist of two main sessions:

  1. In the morning session we will be focused on 14C-materials and GMP requirements.
  2. In the afternoon session several pharmaceutical companies will share their microtracer study designs and experiences. Among confirmed speakers are leading human ADME scientists of GSK, Roche, Boehringer Ingelheim, BMS, PTC Therapeutics, and Pfizer.

Advantages of using microtracer studies

Microtracer studies have found broad application in early clinical drug development over the past ten years. Especially human ADME and Absolute Bioavailability (ABA) single-arm microtracer studies have found traction among both large and smaller sized pharmaceutical companies.

The discriminating factor of microtracer studies is mainly the use of very small amounts of the radioactive tracer material, while the cold dose remains at a therapeutic level.

The advantages can be summarized as:

  • Elimination of animal (QWBA) dosimetry studies
  • The use of fit-for-purpose 14C-material GMP approaches.
  • The early availability of human metabolite profiles with the consequent elimination of radioactive animal and late stage human ADME studies.
  • No necessity to generate intravenous toxicology data for the ABA study because the intravenous microtracer dose is only a small fraction compared to the concomitant therapeutic level oral dose.

Microdosing Network meeting

On April 22nd, a meeting of the International Phase-0 Microdosing Network will be held at the same location, Fletcher Hotel Leiden. The meeting will cover Phase 0 approaches in the broadest sense and is led by Tal Burt. Registration for this Phase 0 meeting is through the Tal Burt Network directly.

Location

The symposium will be held in the Fletcher Hotel Leiden, in the Netherlands.
