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) […]


Front-loading biosimilar development with analytical characterization

Abstract: An online roundtable discussion entitled ‘Front-loading biosimilar development with analytical characterization’ was hosted by BioPharmaSpec. The panellists discussed different regulatory approaches to the clinical trials needed for approval and how this can affect structural and functional characterization; the best way to ‘front-load’ characterization Submitted: 18 June 2022 Revised: 19 July 2022; Accepted: 20 July […]


Structural characterization methods for biosimilars: fit-for-purpose, qualified or validated

Abstract: Detailed and accurate structural characterization of biopharmaceuticals is of paramount importance for product definition, assessment of impurities and achieving in-depth understanding of manufacturing processes. But how can we have confidence in the data obtained from characterization studies? The expectation from regulatory authorities when assessing methods for product characterization is that there will be some […]
