This webinar will focus on primary packaging, where the drug product will be in direct contact with the container closure system for a substantial period of time before reaching the patients. The physico-chemical interactions between the primary packaging components and the drug play a crucial role in the generation and release of subvisible particles. These particles could affect the safety and efficacy of the drug product and not meeting global regulatory standards. To address these concerns, we would like to present the background and tools used for evaluating the release of subvisible particles such as silicone oil droplets.

We leverage our expertise as a leading drug primary packaging manufacturer and as an independent laboratory analyzing the subvisible particle release with a focus on the silicone oil droplets to present:

– State of the art characterization of the release and generation of subvisible particles, such as silicone from container closure systems.
– Regulatory requirements described in USP, EP, JP, and ISO.
– Case studies demonstrating how to approach and test subvisible particle release on prefillable syringes:
– Optimization of the siliconization process to minimize the silicone oil droplets release
– Simulation study on the siliconization downstream processes such as filling, transport stress and extrusion.

Who should attend:

– Packaging Development Engineers/Scientists
– Supply Chain/Clinical Operations
– CMC Scientists
– Quality Directors/Managers/Engineers
– Team Leaders/Directors of Drug (Formulation) Development Teams
– Drug Delivery/Combination Product Scientists and Engineers
– Analytical Scientists
