Preparation Process Development focuses on developing stable, manufacturable, and patient-compatible formulations for biologics by optimizing formulation composition, process parameters, and packaging compatibility. Protheragen provides comprehensive formulation and drug product process development services for antibody and AOC CDMO programs, including developability assessment, formulation screening, process development, fill-finish optimization, scale-up support, and process characterization.
Overview of Antibody & AOC Preparation Process Development
Formulation development is a critical stage in biologics development that aims to maintain therapeutic protein stability, activity, and quality throughout manufacturing, storage, and administration. For antibody-based therapeutics, including monoclonal antibodies, bispecific antibodies, and fusion proteins, formulation development typically involves evaluating molecular stability, selecting suitable excipients, optimizing formulation conditions, developing manufacturing processes, and performing stability and compatibility studies. A robust formulation strategy enables successful transition from preclinical development to clinical trials and commercial manufacturing.
