Biosimilar antibody drug conjugates: considerations of higher order structure and aggregation

Abstract: Undoubtedly the complexity of antibody drug conjugate (ADC) molecules where three components (monoclonal antibody, cytotoxic drug and appropriate linker) are involved poses a challenge for biosimilar development. As with all biomolecule development, both novel and biosimilar, it is important to choose orthogonal analytical techniques to interrogate Quality Attributes, particularly for higher order structure (HOS)…
