FDA Trims, Updates Biosimilars Labeling
FDA is seeking public comment on the usefulness of biosimilarity statements in the product labeling. In an online post, CDER Office of Therapeutic Biologics and Biosimilars director Sarah Yim says FDA is recommending that all labeling for biosimilars, including interchangeable biosimilars, include a biosimilarity statement, rather than both a biosimilarity statement and an interchangeability statement.
Yim writes that while the prescribing information is written for healthcare professionals, information about interchangeability is relevant for substitution at the pharmacy. “We believe that statements in the prescribing information identifying that products have been approved as interchangeable with the reference product and describing the interchangeability standard are not necessary for informing the safe and effective use of the product to prescribing healthcare professionals,” she says…. “Moreover, as we gain more experience with licensing biosimilar and interchangeable biosimilar products, we are finding that a single biosimilar application and associated prescribing information may include both biosimilar and interchangeable biosimilar products at the same time.”
Yim also notes there may be inaccurate perceptions that interchangeable biosimilars are safer or more effective than biosimilars that are not approved as interchangeable. “The interchangeability designation does not indicate a higher level of biosimilarity,” she explains. “Healthcare professionals can prescribe both biosimilar and interchangeable biosimilar products in place of the reference product with equal confidence that they are as safe and effective as their reference products. Including biosimilarity statements in the prescribing information for both biosimilar and interchangeable biosimilar products may avoid confusion among healthcare professionals about the significance of FDA’s determination that a biosimilar is interchangeable with the reference product.”
