For vial containment and pre-filled syringe systems, it is essential to maintain drug sterility over shelf life. Ordinarily, such maintenance comprises prevention of ingress of oxygen, water, and microbes. To demonstrate this, it is essential to perform "container closure integrity testing” (CCIT), or leak testing.

Parenteral drugs that are moisture sensitive are produced in a lyophilized state to protect against product degradation caused by moisture. As a result, when considering the stability and shelf life of lyophilized drugs, the residual drug moisture content is critical. It is also a crucial component in the dossier submitted for regulatory filing, which begs the question: How shall the moisture level in the lyophilized drug product cake be maintained during the drug product’s shelf life?

What does it mean to have package integrity for your container closure system? It means an absence of breaches that can lead to product loss or ingress. Container closure integrity testing should not be just a “one and done” study. It should be understood throughout the life cycle of the product.
