Selection of a Primary Container Closure System Capable of Maintaining Closure Integrity during Cold Storage at -80°C

Advanced therapies are rapidly becoming a reality, targeting unmet patient needs and treatments for diseases with limited therapeutic options. Some advanced therapies, such as gene therapy and mRNA, require cryopreservation due to their fragile nature at room temperature, putting unprecedented expectations on the packaging systems to maintain Container Closure Integrity (CCI) during storage at -80°C. The quality, patient safety, and high value of these therapeutics can be jeopardized if the chosen containment system doesn’t consistently maintain a sterile barrier from when the drug is packed through to administration to the patient. During cooling between room temperature and -80°C, common vial system components such as glass vials, elastomeric closures, and aluminum seals exhibit contraction and changes in physico-mechanical properties. These changes in material properties and component dimensions may affect the system’s ability to maintain closure integrity, resulting in the formation of transient leaks.

In this joint study conducted by West and Corning, we discuss results from four experiments that explore the influences of capping pressure, cooling rate, dimensional changes, and long-term storage at -80°C on the system’s ability to maintain closure integrity. Both Helium leak testing and laser-based gas headspace analysis were used to monitor the closure integrity. The key result of the study is a combination of vial system components and capping conditions that maintain container closure integrity when cooled to and stored at -80°C

  • Webinar Design of a New Elastomer Formulation for Lyophilization Applications

    4040/40 elastomer formulation was designed with ‘future in mind’ to meet the ever-increasing performance & quality standards expected of primary drug packaging. The presentation will summarize the extensive Quality by Design (QbD) process that was undertaken to develop this new formulation as well as considerations taken for closure design dedicated for Lyophilization applications. Details of the extensive characterization that was performed as part of product development as well as data to demonstrates the overall performance of the new rubber formulation for lyophilization stoppers with respect to Extractables/Leachables, Particulates, Moisture, Container Closure Integrity (CCI), Particles and Manufacturability will be presented.
  • Webinar How Market Trends Drive Innovation and Enable the Pharmaceutical Pipeline

    Our healthcare industry is evolving. The move from IV to SC injection is being driven by lifecycle management, biosimilar adoption, and the hospital to home trend. Molecules are getting more complex, and patients drive the preference for self-administration resulting in the need for more complex combination product development and quick scale up. We will present innovative solutions to these challenges to help speed up drug development and enable patient choice with: A 2.25mL polymer container system for auto-injectors which protects sensitive molecules A large volume cartridge plunger to enable primary containment within an on-body delivery system A small pack, high quality glass containment system to enable quick delivery in early-stage development
