Biosimilars: They May Look the Same, but One is a Real Stinker


Biosimilars by nature look much like their comparator products, but they sometimes behave quite differently. That’s because the two products often originate from different cell lines or expression systems. And no matter how hard you strive for parity in the way they’re cultured, minor differences in manufacturing can lead to sticky variations in primary amino acid sequence, glycosylation chemical modifications and protein folding issues. The FDA understands biosimilar products sometimes behave differently than their name-brand counterparts. But, they do expect you to understand why those differences occur, and to demonstrate that they have no clinical significance. That’s where ABC Laboratories comes in.

Biosimilarity: Can You Spot the Differences Between the Bunnies? Now Can You Spot When the Differences are Clinically Significant?


Attempting to create an exact duplicate of the comparator product would be a fool's errand. Variations such as primary amino acid sequence, glycosylation chemical modifications and protein folding issues are common. Your challenge is to determine whether those differences have clinical significance—and when they do, to make well informed mid-course adjustments to keep development moving forward.

Choosing the Right Analytical Partner May Be the Most Economically Important Decision You Make

Recent FDA guidance calls for a "complete and thorough" CMC section that begins with extensive comparative characterization of the biosimilar and reference products. This information is used to substantiate chemical, physical and bioactive similarity, which ultimately will influence the scope and number of animal and clinical studies that will be required to demonstrate interchangeability. In other words, a deficit in analytical characterization expertise can equate to a great deal of...
