biosimilaradjective Referring to a biosimilar therapeutics agent.
noun A biopharmaceutical which is produced by a different manufacturer after the expiration of the patent and marketing exclusivity of an original innovative biological product (e.g., a therapeutic monoclonal antibody).
In contrast to small (non-biological) agents, for which manufacturing an equivalent product is a relatively straightforward chemical process, biosimilars are not produced from the original clones and cell lines used to produce the tested and proven-effective agent; they thus may have therapeutic and metabolic profiles that differ from the clinically tested and proven products.
