Implementing continuous process improvements is increasing in priority for the biopharmaceutical industry. Such implementation can be driven by product safety, purity, and stability enhancement opportunities as well as by cost-reduction pressures. Companies invest in projects to improve product quality assurance, safety, and yield as well as production efficiency (1). Such changes may come at any process stage, from early cell-growth methods through final-product packaging improvements. Examples include growth medium optimization, purification column operation optimization, and enhanced recovery during final filling…

Process Improvements Increase Production Capacity of a Legacy Product
Implementation of postlicensure process improvements in the biopharmaceutical industry can benefit patients and drug manufacturers alike. Here we demonstrate through a case study how a change to the cell culture medium and process can be taken from proof of concept through scale-up to demonstration of feasibility. We further illustrate the scope and complexity of implementing a change in commercial manufacturing to realize significant benefits such as increased production capacity over an existing legacy process. The Importance of Postapproval Improvements Drug…
