Subvisible Particles on Siliconized Prefillable Syringes

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.

Webinar abstract:

This webinar focuses 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 package 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 at Stevanato Group would like to present to you the background and tools used for evaluating the release of subvisible particles such as silicone oil droplets.

Key Learning Objectives:

  • 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
  • Cases 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

The speakers:

  • Abizer Harianawala - US Technical Excellence Center (TEC) Site Leader
  • Gregory Fahs - Research Scientist, Stevanato Group US Technical Excellence Center (TEC)
  • Martina Marchioro - Research Scientist, SG Lab Analytics
