Transformation of Toxicology data into Specific PDE’s
23rd April 2020 | 10:00am PDT, 1:00pm EST | Kim Li, PhD, DABT, MPH Principal Scientist, EHSS Product Stewardship Toxicology at Amgen Inc and Dries Cardoen, Team Leader of Study Directors at Nelson Laboratories, LLC |BOOK FREE SEAT FOR THIS WEBINAR
Permitted Daily Exposure (PDE) has origin in ICH Q3C: Impurities – Guideline for Residual Solvents. This webinar will discuss the principles and methods of applying PDEs to extractactables and leachables (E&L) impurities in pharmaceutical products. We will review the regulatory advice on the DO’s and DON’Ts. Then we will review the current toxicology risk assessment practice on data gathering, literature synthesis and selection of the critical studies with robust toxicity endpoints. We will show how the toxicity endpoints are transformed into chemical-specific PDE values with modifying factors. We will highlight the importance of clinical relevance to further refine the PDE values. For a case study, we will share an extraction study of a polyolefin bag for use with a lyophilized product. We will examine the risk matrix per USP <1664> Assessment of drug product leachables associated with pharmaceutical packaging/delivery systems. The toxicology assessment of the extractables profile of the bag will illustrate the derivation of chemical-specific PDEs, as well as the refinement by taking clinical relevance into consideration.
