Revised Draft Guidance Released
The FDA published a revised draft guidance titled "New and Revised Draft Q&As on Biosimilar Development and the BPCI Act (Revision 4)" on March 10, 2026. If you make biosimilar drugs, you can submit electronic or written comments; comments must be submitted by May 11, 2026 for consideration before FDA begins work on the final guidance.
Non‑U.S. Comparator Data Guidance
The revised Q&A I.8 (now split into parts a and b) explains when a clinical study that used a non‑U.S.‑licensed comparator product could help meet the section 351(k)(2)(A) requirements and support biosimilarity to the U.S.‑licensed reference product. FDA is asking for public comment on when clinical data using a non‑U.S. comparator is acceptable and on the usefulness of analytical comparisons between the non‑U.S. comparator and the U.S. reference.
Aim to Speed Affordable Treatments
FDA states that clearer guidance on biosimilar development is intended to enhance transparency and facilitate the development and approval of biosimilar and interchangeable products, which could help speed bringing more affordable biological treatments to patients. The draft guidance is part of FDA's ongoing effort to update Q&As and policies that affect biosimilar availability.
Specific Q&As Withdrawn for Revision
FDA is withdrawing Q&As I.8, I.10, and I.19 from the final guidance issued September 20, 2021 and reissuing the final guidance solely to remove those Q&As while FDA revises them. FDA says it will continue to evaluate other Q&As in the final guidance and update any that no longer reflect the Agency's current thinking.
FDA Seeks Cost Impact Information
As FDA develops the final guidance, the Agency will consider public comments on costs or cost savings that the guidance may generate, as relevant to Executive Order 14192. Comments on cost impacts can be submitted by May 11, 2026.
