Retention Report
An independent review of FDA’s user fee program for biosimilars found that first-cycle approval rates were higher (67%, 14 of 21) during the first four years of the current five-year program than during the program’s 2013-2017 baseline first five years (39%, 9 of 23). The assessment said that “based on the quantitative data, observations, and feedback from interviews, it is reasonable to conclude that the BsUFA II Program has created conditions that enhance the ability of applicants and FDA reviewers to work toward application approval in the first review cycle.”
