Lyophilization of High-Concentration Protein Formulations

WebThe term “high-concentration protein formulation” (HCPF) is often used, but hardly ever defined. We have therefore asked, how highly concentrated can a protein formulation become? We consider this question, particularly for monoclonal antibody drugs, along with the rationale for developing HCPF and the issues encountered during formulation.
