Critical Factors for Fill–Finish Manufacturing of Biologics

Over recent decades, protein-based therapeutics have emerged as key drivers of growth in the pharmaceutical industry. Drug development pipelines have filled with biologics, and a handful of monoclonal antibody (MAb) products have become some of the best-selling drugs around the world. Production of biotherapeutics is often challenging because of the inherent instability of these large, complex molecules. Their fragile nature has forced manufacturers to change how bulk drug substances (BDSs) are handled and final drug product is formulated, sterile filtered,…
