Biosimilar Analysis Solution

Biosimilars are highly similar to the reference product, with no clinically relevant differences in terms of purity, potency, and safety. And biosimilars are officially approved versions of original "innovator" products and can be manufactured when the original product's patent expires. However, biosimilars may be sensitive to tiny changes in manufacturing processes because of their high molecular complexity. Before the animal and clinical trials, biosimilars need to be characterized according to the guidance document ICH Q6B, which provides a uniform set of internationally accepted specifications for the characterization of biological and biotechnological products for approval.
