BioRationality: The FDA Sets Sights on Removing Clinical Efficacy Studies for Biosimilars

The Center for Biosimilars connects professionals with insights on biosimilars, health economics, regulatory outcomes, and emerging treatment paradigms.

Fifteen years have passed since the Biologics Price Competition and Innovation Act (BPCIA) transformed the biosimilar landscape. Today, we are at a crucial point: the FDA has finally removed clinical efficacy studies for all biosimilar molecules, marking the most significant regulatory change in biosimilars' history.

“we'll be releasing new draft guidance today to remove the comparative study requirement for biosimilar applications. It should shave off 3-4 years from the approval process.”

According to FDA Commissioner Marty Makary, MD, MPH, this change was announced at GRxBiosims2025 on October 29, 2025.
