Container Closure Integrity
Integrity of the closure of a drug product container/delivery systems is crucial to guarantee safety and efficacy. Methods (deterministic and probabilistic) to measure this have recently been set forth in USP Chapter 1207. This section presents papers discussing methods (e.g., helium leak, gas headspace, high-voltage leak detection) and their application to various systems.

Discusses proper sealing parameters and the effects of temperature and time on vial/stopper performance and CCI.
Radiolabeled protein molecules are used to demonstrate that there is less adhesion to a vial made of Daikyo Crystal Zenith® cyclic olefin polymer (COP) than to a glass vial, and that COP enables better recovery of protein. <p><em>A. Leece, et al. Applied Radiation and Isotopes, 80, 99-102 (2013)</em></p>
This article demonstrates that vials comprising Daikyo Crystal Zenith<sup><sup>®</sup></sup> cyclic olefin polymer are well-suited to cryogenic storage/transport of cell therapy products. <p><em>E. Woods, et al. Regen. Med., 5 (4), 659-667 (2010)</em></p>

This report discusses FDA thoughts on how both sterility testing and container closure integrity testing may be used to evaluate the performance of drug product packaging systems.
This article considers the fundamentals of gas headspace analysis for the measurement of container closure integrity – the physics of the process is described along with the types of containers for which it is suitable. <p><em>D.I. Duncan and J.R. Veale (Lighthouse Instruments)</em></p>
This presentation considers several different methods of measuring container closure integrity, and compares their relative utilities: (a) vacuum decay (loss of vacuum in evacuated chamber due to failure of container), dye ingress (visual observation of colorized fluid moving into container), ultrasonic (air pockets where container components join). <p><em>H. Wolf (PTI Inspection Systems)</em></p>
This poster considers the use of gas headspace analysis for the measurement of container closure integrity of syringes. The method can distinguish differences in gas permeability between plunger and tip, and between staked needle and Luer lock configurations. <p><em>J.R. Veale and K.G. Victor (Lighthouse Instruments).
