Clarity and Truth in Advertising: FDA Finalizes Guidance on Promotional Labeling for Biologics and Biosimilars
The US Food and Drug Administration (FDA) has finalized important guidance on the promotional labeling and advertising of reference listed drugs (RLDs), biosimilar products, and, crucially, interchangeable biosimilar products. The primary goal of this document is to ensure that all promotional communications about these products are accurate, truthful, and non-misleading. The publication fulfills a legal requirement (Biosimilar User Fee Amendments of 2022 – BsUFA III) and aims to address industry questions, establishing clear standards for presenting scientific data and information about interchangeability, a key concept for the adoption and success of the biosimilars market.
