Biosimilars are FDA-approved biologics that have undergone an extensive regulatory evaluation and approval process proving they match the reference medicine in terms of quality, safety and efficacy.1,2
Confirmatory clinical studies have shown that there is no clinically meaningful difference in terms of safety, purity and potency between biosimilars and their reference biologic.2,3
Once a biosimilar is approved for one indication, extrapolation based on totality of evidence can allow expansion of its use to other indications for which the reference biologic is approved.2
In a systematic review of 90 studies on switching from a reference medicine to a biosimilar, which included 7 biosimilars across 14 disease states and 14,225 individuals, the majority of the publications did not report differences in immunogenicity, safety orefficacy.4
