Biosimilar Analysis Workflows

Easily establish structure of biosimilar drugs

In the US, biopharmaceutical innovators have 12 years of patent protection for biologic medicines, at which point it becomes possible for biosimilar and biobetter sponsors to market similar therapeutic protein products.

The FDA has published the scientific consideration for demonstrating biosimilarity to a reference product, which provides insight how they will evaluate biosimilar biological products.

In order to establish the biosimilarity of a therapeutic drug candidate to the original innovator molecule, both proteins must be exhaustively structurally characterized for a number of criteria—all covered in International Council for Harmonization guidelines ICH Q5E and ICH Q6B.
