Enhanced Biosimilar Product Characterization: A Case Study Using Raman Spectroscopy Combined with Dynamic Light Scattering

Biophysical characterization has drawn great attention from the biopharmaceutical industry and regulatory agencies across the globe, especially for use in biosimilar drug product development. Currently available biophysical characterization tools can help in screening and optimizing better (more stable) formulations for such products. However, most tools cannot be used for head-to-head comparison of the biophysical properties of an optimized biosimilar formulation with those of an innovator product at higher concentrations. We developed and optimized a formulation for monoclonal antibody MAb B…
