Current Industry Best Practice on in-use Stability and Compatibility Studies for Biological Products.

Evaluating the in-use stability of a biological product including its compatibility with administration components allows to define handling instructions and potential hold times that retain product quality during dose preparation and administration. The intended drug product usage may involve the dilution of drug formulation into admixtures for infusion and exposure to new interfaces of administration components like intravenous (iv) bags, syringes, and tubing. In-use studies assess the potential impact on product quality by simulating drug handling throughout the defined in-use period. Considering the wide range of in-use conditions and administration components available globally, only limited guidance is available from regulators on expected in-use stability data. A working group reviewed and consolidated industry approaches to assess physicochemical stability of traditional protein-based biological products during clinical development and for commercial use. The insights compiled in this review article can be leveraged across the industry and encompass topics such as representative drug product material and administration components, testing conditions, quality attributes evaluated and respective acceptance criteria, applied quality standards, and regulatory requirements. These practices may help companies in the study design, and they may inform discussions with global regulators.
