Abstract

Biological safety assessments for drug-device combination products involve evaluation of the drug container closure and the device constituent part. When the device constituent part is the drug delivery system as well as the drug container closure system, both device and drug-based packaging standards have been deemed applicable. Approaches used for the biological safety assessment of medical devices differ from those used for pharmaceutical packaging/delivery systems. One area of difference is the extent to which chemical characterization with toxicological assessment is used either in addition to, or in place of, biological in vivo or in vitro tests. Differences also exist in the way nonclinical studies are used to evaluate the safety of medical devices or drug delivery systems. The lack of alignment in standards and guidance has resulted in confusion over what combination of tests and methods of evaluation constitute a biological safety assessment that will meet regulatory expectations for a drug-device combination product. The intent of this manuscript is to discuss the challenges created when the packaging or delivery system is also a device constituent part of a drug-device combination product. Suggestions are offered regarding approaches that may be useful for conducting suitable biological safety assessments for drug-device combination products.
