A Deep Dive into the Characterization of a Complex cIEF Electropherogram from an ADC Using a Novel Integrated icIEF-UV/MS System
Charge heterogeneity is present in most biopharmaceutical protein products. During the manufacturing process, charge heterogeneity of the protein therapeutics can occur due to enzymatic cleavage and chemical post-translational modifications (PTM). For therapeutics like ADCs, not only the antibody contributes to the heterogeneity but also the linker and payload, which add even more complexity to the charge variant profiles. Characterizing the charge heterogeneity of ADCs is essential for critical quality attribute (CQA) assessment to ensure drug safety, efficacy, and potency.
The Role of Forced Degradation in Method Development, Manufacturability, and CMC Strategy
April 28th 2025Forced degradation studies are critical in biologics development, particularly for monoclonal antibodies (mAbs). These studies simulate long-term environmental stressors to uncover degradation pathways and ensure the stability of critical quality attributes (CQAs), aiding in robust chemistry, manufacturing, and controls (CMC) strategies and regulatory compliance.
