Program Highlights

This training course will look at Extractables and Leachables from many different angles: definitions, regulations, material and polymer science, analytical E/L methodologies, safety assessments, and study design for different parenteral primary packaging systems and injection devices.

Note In response to considerable demand, all participants will now be given access to electronic course notes, which may be printed once for use during the course approximately 1-2 weeks in advance. Hard copies of course notes will be no longer provided to participants.

When making parenteral drug products, pharmaceutical companies are faced with the need to further investigate the materials that will be in contact with the drug product, either during manufacturing, intermediate storage, storage in its final packaging, or during the delivery of the drug to the patient. While historically, the potential safety issues were the main driver in these kinds of investigations, recently, quality issues (i.e. for biopharmaceuticals) have also become a concern.

This training course will look at Extractables & Leachables from many different angles, including, Definitions, Regulatory, Material & Polymer Science, Analytical E/L Methodologies, Safety Assessments, and Study Design for different parenteral primary packaging systems and injection devices.

A full session will be dedicated to an in-depth update on regulations, standards, and recommendations in this field (PQRI, USP, ISO 10993, BPOG).

Upon completion of this training course, you will be able to:

  • Explain in detail the current regulatory requirements for container/closure qualification form an E/L perspective.
  • Explain the upcoming changes in regulations, standards and recommendations from PQRI, USP and BPOG and how these changes could impact a future evaluation of a pharmaceutical C/C-system.
  • Understand the materials of construction, including composition, of container closure systems, and how they could impact the safety and quality of a parenteral drug product.
  • Put together an evaluation program (review of provided documentation, analytical testing) of different types of parenteral drug product container/closure systems.
  • Perform a safety/risk assessment of analytical results, obtained after completion of an E/L study
