Over the last years, the requirements on the assessment of substances that could leach into the drug product in the course of its life cycle have increased considerably.
The specific kind of extractable/leachable can vary from organic oligomers and catalyst residues to heavy metals – to name a few. Due to the resulting complexity, it is very important to consider the potential risk factors associated with leaching substances already at a very early stage in process development. Therefore, the ICH is currently working on a new ICH Q3E Guideline for Extractables and Leachables (E&L) to “assist both applicants and regulators by providing focus on critical aspects, and improving transparency in requirements for medicinal products including drug delivery device components”.
Packaging materials have been in the focus of such investigations for a long time as the contact time between drug product and packaging material is rather long.
But in addition, you have also to consider other possible sources of contamination. Recently, particular attention was paid to devices and equipment used in the production process itself, e.g. filters, bags, tubes. The trend towards single-use equipment might relieve the pressure on cleaning validation and the need to introduce control strategies along the supply chain to avoid unintentional added impurities in materials. At the same time E&L testing will become a topic of major concern.
Within the scope of this Live Online Training, all relevant aspects of Pharmacopoeia/GMP-compliant E&L testing will be addressed ranging from regulatory requirements to routine testing in quality control.
Experienced industry & authority speakers share their in-depth knowledge with you.


This Live Online Training is designed for personnel of pharmaceutical companies and their suppliers who
  • are responsible for setting up E&L studies.
  • perform E&L testing.
  • work in quality control of packaging materials.
  • specify and select polymeric, glass and rubber materials in process development.
  • specify and select Single Use Equipment for manufacturing.
  • develop materials sourcing strategies.

Technical Requirements

For our Live Online Training Courses and Webinars, we use Cisco WebEx, one of the leading suppliers of online meetings.

At http://www.webex.com/test-meeting.html you can check if your system meets the necessary requirements for the participation at a WebEx meeting and at the same time install the necessary plug-in.  Please just enter your name and email address for the test. If the installation is not possible because of your rights for the computer system, please contact your IT department. WebEx is a standard nowadays and the necessary installation is fast and easy.
