Container Closure Integrity Testing (CCIT)
Qiang Liu, PhD, Research and Development Supervisor

The container closure system for a drug product provides critical protection for stability and sterility. Contaminants (such as microorganisms and reactive substances) could potentially cross through defective container closures putting the drug product and patients at risk. USP chapter <1207> defines the concept of container closure integrity as "encompassing the absence of all package leaks that risk product quality". FDA also introduced container and closure system integrity testing in lieu of sterility testing as a component of a stability protocol for sterile products.

Among a variety of CCIT tests, dye ingress testing is one of most commonly used methodologies. During the test, the container closure test articles are put into an empty vacuum chamber to introduce negative pressure to the articles. This vacuum removes air inside the container/closure system. The vacuum is then released and methylene blue hydrate solution enters the chamber until it reaches atmospheric pressure. The articles are removed from the chamber, rinsed, patted dry, and examined for the presence of methylene blue through visual inspection or spectrometry. To pass the test, there must be no detectable methylene blue inside any of the tested container closure systems. ARL provides CCIT services for a variety of container types and compounds including colored compounds such as Methylcobalamin, Cyanocobalamin, and Mitomycin.

The sensitivity and applicability of CCIT methodologies varies based on container type, size, fill volume, and compounded drug product. ARL recommends and provides CCIT method validation services for clients' specific container closure system.

Avastin Stability and Release Testing
The FDA requires pharmacies and outsourcing facilities perform a formal stability study on repackaged Avastin (bevacizumab) exceeding the allowable 8-24 hour use period.

A stability study on Avastin must include the following tests: 
  • Appearance (Color and Clarity / Visible Particulates)
  • pH (USP <791>)
  • Subvisible Particles (Particulate Matter USP <788>)
  • Protein Content
  • Product-related impurities (Protein Aggregation and Protein Size and Charge Variants)
  • Potency
  • Sterility
  • Endotoxin
Sterility, endotoxin, color, clarity, visible particulate, and subvisible particle testing are also required for the release of each new batch. 
ARL is one of a select few labs in the industry that provides stability and release testing services as per FDA guidelines.
For additional information on Avastin testing services, contact ARL at 800-393-1595 or

Join us for Stability Studies: The Architecture Behind Establishing a Beyond-Use-Date Webinar
Thursday, September 20, 2018, 12 p.m. CST
This webinar will describe the thought processes that must occur to successfully design a stability study.  We will begin by discussing how stability indicating methods, the foundation of a stability study, are developed and validated.  We will then construct stability studies based on a variety of formulations and routes of administration.  Please join ARL as we give a behind the scenes look at the architecture of stability studies.  

1 hour of CE provided at no cost. 

Contact or call 800-393-1595 with questions.
