The documents posted on this site are XML renditions of published Federal
Register documents. Each document posted on the site includes a link to the

The OFR/GPO partnership is committed to presenting accurate and reliable
regulatory information on FederalRegister.gov with the objective of
establishing the XML-based Federal Register as an ACFR-sanctioned
publication in the future. While every effort has been made to ensure that
the material on FederalRegister.gov is accurately displayed, consistent with
the official SGML-based PDF version on govinfo.gov, those relying on it for
legal research should verify their results against an official edition of
the Federal Register. Until the ACFR grants it official status, the XML
rendition of the daily Federal Register on FederalRegister.gov does not
provide legal notice to the public or judicial notice to the courts.

SUPPLEMENTARY INFORMATION:
I. Background
FDA is announcing the availability of the draft Strategy Document titled “BsUFA III Future Needs in the Development of Interchangeable Products Post-Workshop Strategy Document.” In section II.D.3 of the BsUFA III commitment letter (available at
https://www.fda.gov/media/152279/download?attachment), FDA agreed to hold a public scientific workshop on the development of interchangeable biosimilar products to help identify future needs (
e.g.,
guidance, research). FDA also agreed to issue a draft strategy document for public comment outlining the specific actions FDA will take to facilitate interchangeable biosimilar product development within 12 months following the public workshop. The public workshop was held on September 19, 2025 (90 FR 39395), with both virtual and in-person attendance, and representatives from trade associations (Association for Accessible Medicines (AAM), Pharmaceutical Research and Manufacturers of America (PhRMA), and Biosimilars Forum) provided their perspectives on future needs for development and adoption of interchangeable biosimilar products. FDA speakers from the Center for Drug Evaluation and Research discussed scientific topics related to analytical data considerations, user interface and human factors considerations, and other considerations to facilitate development of interchangeable biosimilar products. The draft Strategy Document summarizes the discussion that occurred during the workshop as well as comments received in the public docket. The major themes identified during the workshop and in comments submitted to the docket included timely communication of new scientific and policy developments, challenges with user interface development and human factors analyses, and approaches to interchangeability that follow the evolving science. Over the last 5 years, the development and approval of interchangeable biosimilar products have advanced considerably. FDA's future efforts will focus on continuing to follow the evolving science, providing educational resources for healthcare providers and patients, and helping to ensure that stakeholders have confidence in the safety and effectiveness of interchangeable biosimilar products.
