Myths, Risks, and Best Practices: Production Cell Line Development and Control of Product Consistency During Cell Cultivation

Health authorities are requesting substantial details from sponsors regarding practices used to generate production cell lines for recombinant DNA–(rDNA) derived biopharmaceuticals. Authorities also are asking for information about the clonality of master cell banks (MCBs) and control strategies to minimize genetic heterogeneity. Such requests are prompted by recent reports indicating “nonclonality” for certain production cell lines. To address these and related issues, the CASSS CMC Strategy Forum on “Production Cell Line Development and Control of Product Consistency During Cell Cultivation:…
