The Importance of Countering Biosimilar Disparagement and Misinformation

Biosimilar use is limited in some healthcare systems because biosimilars are not well understood by many healthcare professionals and patients. The knowledge gap is exacerbated by disparagement of biosimilars and dissemination of misinformation, whether intentional or otherwise. There are several different types of disparagement and misinformation directed towards biosimilars as a class, including statements about biosimilar science or policy that are factually incorrect; misleading information, where the information is correct, but is provided out of context; incomplete information, where only partial or a limited set of facts are provided; creation of a false narrative, especially in scientific and medical literature, that provides a set of references to support incorrect conclusions; and negative message framing of factual statements to create a negative perception. Disparagement and misinformation about biosimilars can be countered by educational efforts, appropriate oversight, and regulatory activities with the option of enforcement action by governmental agencies, if warranted. Balanced educational materials about biosimilars should be made easily accessible. Physicians, nurses, pharmacists, and patient advocacy groups should work together to provide patients with consistent, positive messages about the value of biosimilars.
