The U.S. biosimilar market is coming of age under the BsUFA II agreement, but there are a few steps the FDA could take to help it develop more predictably. For starters, the agency should conduct pre-approval inspections earlier in the 12-month biosimilar review cycle to give sponsors time to address unexpected issues, industry representatives told the FDA Jan. 27 in response to an independent interim assessment of the enhanced transparency and communication processes included in the current user fee agreement.

If the FDA’s opening meeting Nov. 19 on the reauthorization of BsUFA is anything to go by, interchangeability could be a key part of the next round of U.S. biosimilar user fee negotiations.

As the FDA continues to shift its limited resources to the development and review of COVID-19 therapies and vaccines, other drugs in the pipeline may be delayed. In a question-and-answer guidance released late Tuesday, the agency acknowledged that, going forward, it may not be able to sustain its current performance level in meeting all its goal dates for new drugs and biologics.
