Agency Guidelines for Recombinant Biosimilars of Biopharmaceuticals

All agencies have issued varying guidances for the approval of recombinant biosimilars of biopharmaceuticals, and all submittals are considered on a case-by-case basis. This instalment of “Focus on Biopharmaceutical Analysis” looks at the best methodologies for demonstrating their analytical comparability.

Glycosylation in mAb Therapeutic Products: Analytical Characterization and Impact of Process

Glycosylation of monoclonal antibody (mAb) therapeutics is widely recognized by the regulators and the industry as a critical quality attribute (CQA). Hence, it is necessary that glycosylation is measured and adequately controlled during production. This installment reviews the various process parameters and raw material attributes that affect glycosylation, as well as the different analytical tools that are used for characterization, with greater emphasis on the chromatographic methods of analysis. Key recent advancements that have occurred in the past five years are also discussed briefly. While significant progress has been made in the monitoring of glycosylation, its real time control has yet to be demonstrated.
