Objectives

In Part II of the Impurities Forum the key principles of the new ICH Q3D Guideline will be highlighted. You will get to know the essential aspects and approaches of determining and controlling elemental impurities in drug products.

You will learn
which are the principles of the elemental impurities risk assessment process,
how to implement risk-based strategies to control elemental impurities,
which analytical methods are suitable to determine
elemental impurities and what you have to consider when you apply them,
what you need in your QC lab to be prepared for elemental impurities analytics.

Background

In November 2014 the ICH Q3D Guideline for Elemental Impurities was published as Step 4 document. This document outlines

the evaluation of the toxicity data for potential elemental impurities
the PDEs for each element of toxicological concern
the development of controls designed to limit the inclusion of elemental impurities in drug products to levels at or below the PDE

In March 2015 USP announced a revision to General Notices section 5.60.30 Elemental Impurities in USP Drug Products and Dietary Supplements, establishing 1 January 2018 as the new date of applicability of General Chapters <232> Elemental Impurities-Limits and <2232> Elemental Contaminants in Dietary Supplements. The limits provided in GC <232> align with ICH Q3D Step 4. GCs <232> and <233> Elemental Impurities-Procedures will become official on 1 December 2015.

Also in March 2015 the European Pharmacopoeia decided to delete the reference to the test for heavy metals (2.4.8) from all individual monographs on substances for pharmaceutical use.

Target Group

The conference addresses all personnel involved in development of drug substances and drug products from scientific staff to laboratory heads involved in R&D. The needs of Laboratory Managers, Supervisors and Analysts in pharmaceutical quality assurance and quality control departments will also be covered.
