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.
Biosimilar Analysis Solution at Creative Proteomics
Based on years of experience to support the development of biosimilars, Creative Proteomics can provide comprehensive services, including but not limited to:
- Characterization of protein biosimilar
Creative Proteomics can provide a range of information for characterization of protein biosimilars according to the guidance document ICH Q6B, such as structural characterization, physicochemical properties, process- & product-related impurities, etc.
- Comparison of biosimilars and protein therapeutic
Creative Proteomics can provide a number of physicochemical and biological methods for comprehensive comparison between the biosimilar and the original biologic using multiple analytical methods, such as intact mass analysis by liquid chromatography–mass spectrometry (LC-MS), size exclusion chromatography (SEC), ion exchange chromatography (IEC), etc.
