Protein-based therapeutics, specifically monoclonal antibodies (mAbs), have become the focus of pharmaceutical R&D over the last decade. While these biologics offer many possibilities when it comes to treating a variety of diseases, they also present considerable challenges during development.
All of these factors combined make manufacturing and delivery of protein-based therapeutics very difficult. If these drugs could be produced at lower viscosities, then a lower volume could be used, making subcutaneous delivery possible; this would also significantly reduce the risk of aggregates. Now, a treatment that typically requires an hour in a clinic could potentially become a simple injection at home.
This informative white paper by Althea covers the challenges of crystallization of proteins for therapeutic use and how to preserve efficiency during crystallization.
