Demonstration of Biosimilarity

The demand for biosimilars is increasing as the patent cliff for many blockbuster biologics approaches. Biosimilars require comprehensive analytical characterization to demonstrate similarity to the innovator product. This can be a time-consuming and complex process requiring a range of analytical characterization methods throughout development and production. 

The expert scientists at BioOutsource and Cellca have extensive experience in biosimilar analysis and testing from  working with biopharmaceutical companies across the globe. We provide you with an integrated service to support your biosimilar development starting with innovator sourcing:
