Assessing the impact of product-handling by in-use stability studies

Assessing the impact of product-handling by in-use stability studies

A drug substance not only needs to be stable during product, transport, and storage, but needs to withstand the handling procedures during administration. In a clinical setting, a drug product may be diluted and exposed to different surface materials including as tubings, infusion bags, pumps, closed system drug transfer devices, and filters before it is finally administered to the patient. In-use stability studies aim to assess the effect of such product handling on the stability and integrity of the drug product and thus therapeutic efficacy and safety.

Factors influencing the in-use stability

During an in-use stability study, we assess a variety of factors, including the effect of dilution and the dilution medium, potential adsorption to surface materials, shear forces during application, variations in extractable volume and reconstitution, formation or introduction of aggregates and (sub)visible particles, and more. While individually designing each in-use stability study, we commonly include a selection of the most promising drug product candidates using fresh as well as aged material and assess the stability.
