Engineering a biosimilar

On the basis of a reference biologic’s critical quality attributes (CQAs), a biosimilar is engineered to be highly similar in terms of host cell proteins, product attributes, variants, process impurities, and stability profile.

Characterization and comparative studies

High similarity in analytical and pharmacokinetic/pharmacodynamic (PK/PD) data between the reference biologic and the biosimilar indicates a lower risk of clinical differences.

Quality standards in manufacturing

Rigorous quality standards throughout the manufacturing process and extensive risk assessments to promote quality.

At Amgen, we excel at the highly specialized, iterative process of developing monoclonal antibodies in vitro, scaling up the optimal cell line, time and again, in large-scale bioreactors, and checking and rechecking for batch-to-batch consistency.4,5

Screening process
An extensive screening process is used, consisting of the following steps: 4,6-8
Cell culture4
  • Process line development
  • Cell expansion
Recovery and purification
  • Harvest
  • Purification (multiple steps)
  • Virus inactivation/removal
Formulation to distribution
  • Filling
  • Finishing
  • Packaging and storage
  • Quality assurance and characterization
  • Stability testing

Our biologic medicines are manufactured using living cells engineered to produce therapeutic proteins in large quantities. Those cells are very sensitive to conditions produced during their synthesis and handling, and a series of culturing and purification steps are required to produce a consistent, quality active ingredient.9

The complexities of biosimilar manufacturing
When manufacturing a biosimilar, only the reference product’s amino acid sequence is known. From there, the biosimilar candidate requires considerable preclinical optimization.2

All of the complexities of manufacturing innovator biologics apply to biosimilar medicines as well. But biosimilar creation also has its own set of intricacies.
