The COVID-19 pandemic highlighted the urgent need for life-saving treatments, including vaccines, drugs, and therapeutic antibodies, delivered at unprecedented speed. During this period, recombinant antibody research and development cycle times were substantially shortened without compromising quality and safety, thanks to prior knowledge of Chemistry, Manufacturing and Controls (CMC) and integration of new acceleration concepts discussed below. Early product knowledge, selection of a parental cell line with appropriate characteristics, and the application of efficient approaches for generating manufacturing cell lines and manufacturing drug substance from non-clonal cells for preclinical and first-in-human studies are key elements for success. Prioritization of established manufacturing and analytical platforms, implementation of advanced analytical methods, consideration of new approaches for adventitious agent testing and viral clearance studies, and establishing stability claim with less real-time data are additional components that enable an accelerated successful gene to clinical-grade material development strategy.
