A Study of Leachables for Biopharmaceutical Formulations Stored in Rubber-Stoppered Glass Vials
A systematic approach facilitates formulation component selection.

A well-designed study can help a biopharmaceutical company build quality and efficiency into its biopharmaceutical product design and in-process development and commercialization. This approach provides a knowledge base for a better selection of product formulation components, with respect to leachables.

Scientific understanding based on data obtained from this particular study can be used to support other pharmaceutical product development processes. For instance, for different rubber stopper materials or other types of container/closure materials, the potential leachables profile can be predicted based on its extractables profiles and the intended formulation and excipients regime with greater accuracy for the model systems studied. The knowledge and understanding accumulated will in turn aid the product development process and make it possible to develop safer and more efficacious medicines faster.

Based on our study, changes in the components in a biopharmaceutical formulation can lead to appreciable changes in the leachable profiles. A thorough understanding of how various formulation components may affect a leachables profile can aid in selecting appropriate formulation constituents based on the container/closure materials and storage conditions. Such an understanding overcomes the limitations of a traditional selection process and allows the early adoption of a risk-based approach and QbD at the beginning of product development. Consequently, drug development duration can be shortened significantly while product quality, safety, and efficacy are maintained.
