Extractable Study Design and Data Evaluation of Polymeric Product Contact Materials

Concerns over the safety and drug product qualities due to extractables and leachables (E&L) from polymeric Product Contact Materials (PCM), especially single use systems, in the manufacturing, packaging and delivery of biologics have increased in recent years. Based on surveys and author’s experience, almost all major regulatory agencies require the E&L risk assessment of PCM for new biologics license applications (BLA). To ensure the E&L data are suitable for the assessment of intended application of the PCM, the health authorities are paying close attention to the study design, analytical assays employed, and how the extractable data being used to conduct a safety risk assessment of the materials. The key to the success is to ensure the study design and data interpretation is product and process specific. The lack of relevant E&L data from suppliers presents end-users a great challenge. Strategies of developing relevant extractable data and applying that in the toxicological evaluation will be discussed.

Dr. Ping Wang is a Principal Scientist with Janssen R&D. He has been leading Janssen’s effort in the evaluation, selection and risk assessment related to polymeric materials used in the manufacturing, packaging and delivery of biologics, small molecules and transdermal drug products for the past ten years. His main interests and expertise are risk based material evaluation, E&L strategies and methodologies, single use systems, biocompatibility, biologics drug development, analytical technologies, regulatory implications and toxicological assessment of impurities. He is a board member of Extractables and Leachables Safety Information Exchange (ELSIE) Consortium. As an active member of Biophorum Operations Group (BPOG), he was a key contributor to the BPOG’s standardized extractable protocol, and the best practice guide for leachable risk assessment. He earned a PhD in pharmacy, received a Regulatory Affairs Certificate (RAC), and an MBA degree.
