Why Precise Manufacturing of Biological Medicines Matters

How biological medicines are manufactured directly affects their efficacy and safety as medications.

Biological medicines are typically derived from living organisms.1-3 They're made by genetically engineering living cells (also called the cell line)—and a high level of precision is required in the commercial manufacturing process to produce a consistent biological product each time.3-5 The protein produced by the cells will be influenced by individual cell characteristics, the growing environment and the nutrients provided during the manufacturing process.6 The entire process can take from several weeks to months to complete.7

Once the cell line is established, the manufacturing process may be divided into 3 phases: cell culture, recovery, and purification, fill, and finish.7
