BPC believes that biosimilar product labeling should contain all needed data for physicians to make appropriate prescribing decisions for their patients. The label is a critical tool for physicians to both make prescribing decisions and manage potential adverse events, including side effects and drug-to-drug interactions. As such, it is of the utmost importance that any drug label be complete and accurate. BPC advocates for final labeling guidance that requires more transparent labeling, including: a statement of whether the biosimilar is interchangeable with the reference product and/or other biosimilars on the market; a summary of the full clinical data submitted in support of biosimilar approval or a hyperlink to that date, and the FDA’s summary basis of approval, including identifying where biosimilar properties, structure and function differ from the reference product.
