Biosimilars Sometimes Behave Differently. The Key is Knowing When it Matters.
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.
