Cell and gene therapies are an expanding area with an expected growth rate of 24.7% over the forecast period of 2022-2030 .1
Vial-stopper-seal combinations used as containment systems for these therapies need to maintain container closure integrity (CCI) for extended periods. Achieving CCI can be a particular challenge due to the low storage temperatures required: ultra-low (-80°C) for gene therapies and cryogenic (≤ -130°C, i.e., vapor of liquid nitrogen) for cell therapies.
To determine suitability for gene and cell therapies, West evaluated two vial-stopper-seal combinations based on: Daikyo Crystal Zenith® (CZ) cyclic olefin polymer vials – fluoropolymer (ethylene tetrafluoroethylene)-laminated elastomer stoppers – Flip-Off® CCS seals. Evaluation of CCI was at ultra-low (-80°C) and cryogenic (≤ - 130°C) temperatures.
The following sterilized components, which are available in the Ready Pack™ containment solution, were used:
These components were selected for evaluation based on their ability, among the West portfolio, to present the lowest risk to drug product performance.
Elastomer stoppers laminated with fluoropolymer barrier films are known to be less interactive with selected protein-based molecules than non-laminated elastomer stoppers, based on prior West research.2,3
Polymer vials, such as CZ vials, have intrinsically less interaction with molecules than glass vials, based upon lower surface energy. In prior West research, this has been demonstrated; selected protein-based molecules showed less interaction with CZ vials than with glass vials.4,5 Further, typical elastomer and cyclic olefin polymer have a closer match in coefficient of thermal expansion than typical elastomer and glass.6 Glass and elastomers shrink at different rates as temperatures are lowered, creating the possibility of a breach in the stopper-vial-seal combination. However, CZ vials tend to shrink at the same rate as stoppers, maintaining better level of contact throughout the process and reducing risk of a breach.
A two-year CCI study now has been completed examining systems comprising CZ vials, NovaPure® and Daikyo Seiko fluoropolymer-laminated stoppers, and Flip-Off® CCS seals at -80°C (refrigerator) and ≤ -130°C (dewar with vapor of liquid nitrogen). West validated methods employing tracer gas leak detection with helium (He leak) and gas headspace analysis with O2 were used. Both methods are derived from USP Chapter <1207>.
The results of this study have just been published:

- Strategies to Evaluate CCI of Vial and Syringe Systems over Time and Temperature. 2023 PDA Parenteral Packaging Conference (April 19, 2023)
For all systems, He leak testing verified vial/stopper seal integrity over 2 years at room temperature, -80°C and ≤ -130°C. More critical, though, O2 headspace analysis demonstrated good CCI with no system failure over 2 years at -80°C and ≤ -130°C. See Figures 1 and 2.At ≤ -130°C, no N2 ingress was observed over 2 years. At -80°C, no O2 ingress was observed after 1 year and only slight O2 ingress (5%) was observed after 2 years – most likely from slow diffusion through CZ. Note there was no breach of any sample at -80oC, as that would have resulted in 21% O2 (i.e., atmosphere of refrigerator).

Figure 2. Oxygen Headspace at ≤ -130°C.
At ≤ -130°C, no N2 ingress was observed over 2 years. At -80°C, no O2 ingress was observed after 1 year and only slight O2 ingress (5%) was observed after 2 years – most likely from slow diffusion through CZ. Note there was no breach of any sample at -80oC, as that would have resulted in 21% O2 (i.e., atmosphere of refrigerator).
Based just upon physio-chemical properties, vial-stopper-seal containment systems based on CZ vials and fluoropolymer-laminated elastomer stoppers have the potential to be suitable for gene and cell therapy drug products.
The above studies indicate CZ vial-stopper-seal containment systems can likely provide adequate physical protection and stability of the cell and gene therapy product maintaining the integrity of the drug product throughout manufacturing, storage, and shipment.
In addition, the containment system offerings can work in the manufacturing process and be sufficiently scalable for commercial success.

My name is Michele Polinsky and I am a breast cancer survivor.<br />These days it’s the simple things that make me happy. Watching my daughter play soccer at Virginia Tech, taking my son to high school and watching his soccer games. Celebrating holidays and birthdays. Simple things that you take for granted when you are healthy. And you start to worry won’t be in your future when you are first diagnosed with cancer. It’s a scary time.
Today’s regulatory guidelines and requirements for pharmaceutical manufacturers are getting more specific and stringent, ensuring that drug products are safe and that there is no compromise with the possible use of unsuitable and/or non-compliant packaging components. For instance, regulatory guidelines require use of clean components (inclusive of secondary seals for this context) for sterile filling operations.
The plunger rod is a fundamental feature of a complete syringe drug delivery system. There are three key functional characteristics that all pharmaceutical manufacturers should consider when determining the appropriate plunger rod for a specific drug product and syringe system.
The FDA’s Center for Devices and Radiological Health (CDRH) released four final guidance documents on Thursday, Sept. 12, which provides the FDA’s current thinking on the Special 510(K) program, the Abbreviated 510(K) program, how to format Traditional and Abbreviated 510(K)s and the new Refuse to Accept policy for 510(K).
Overview of EU GMP Annex 1<br />EU GMP Annex 1 is the European Union’s guidelines for good manufacturing practice (GMP) of sterile medicinal products for human and veterinary use.<sup>1</sup> It provides specific requirements for the manufacture of sterile medicinal products, including principles for cleanroom and clean zone design, personnel experience/qualification, and monitoring of manufacturing environments, just to name a few. The objective is to ensure product quality and potency, as well as patient safety, by minimizing risks of microbial, particulate and endotoxin/pyrogen contamination through manufacturing and environmental controls.<br />In August 2022, the final draft of EU GMP Annex 1 was released after years of development and took effect on 25 August 2023. In this blog, a summary of the key changes of relevance to primary packaging components and how West can help with the implementation will be discussed.
