Validating Cross-reactivity to Infliximab Biosimilars

A thumbnail preview of our brochure validating the cross-reactivity to Infliximab biosimilars.

Biosimilars are biologics that are comparable to their reference product with respect to structure, efficacy, safety and quality1. Due to the inherently variable nature of the biomanufacturing process, biosimilars are not identical copies of their reference products1. One of the main concerns with developing biosimilars is the potential for unexpected immunogenicity which may alter the efficacy of the biosimilar2,3. Therefore, with the approval of biosimilars for the treatment of IBD, it is important to research and develop therapeutic drug monitoring (TDM) processes for these drugs to analyze potential differences in immunogenicity, safety, and efficacy profiles2,3,4.
