FDA Replaces Top Regulators Following Commissioner's Resignation

2026-05-16

The BareStory

The U.S. Food and Drug Administration is replacing the acting directors of its primary drug and biologics evaluation centers. The leadership changes follow a broader personnel shake-up at the agency, which includes the recent resignation of FDA Commissioner Dr. Marty Makary.

Dr. Tracy Beth Høeg is leaving her position as acting director of the Center for Drug Evaluation and Research, and Katherine Szarama is stepping down as acting director of the Center for Biologics Evaluation and Research. Høeg claimed in a social media post that she was fired from her role. An agency memo indicated that Szarama will remain at the FDA in another capacity. According to an updated organizational chart, Michael Davis will succeed Høeg, Karim Mikhail will replace Szarama, and Lowell Zeta will become the acting chief of staff.

The division transitions occurred days after Commissioner Makary resigned. A source familiar with the matter alleged that Makary departed due to a dispute over the approval of flavored e-cigarettes, amid broader reports of internal agency tensions and executive pressure. The FDA has experienced multiple high-level turnover events over the past year, including the recent exit of Dr. Vinay Prasad, the former head of vaccine approvals.

A senior administration official stated that the Trump administration intends to name a nominee for a permanent FDA commissioner in the coming weeks. The position will require Senate confirmation.

How it may affect me

As a U.S. reader:

• In the short term, consumers may see shifts in the approval and availability of flavored e-cigarettes, as disagreements and executive directives regarding these products directly contributed to the recent resignation of the FDA commissioner.

• Leadership transitions within the drug, biologics, and vaccine evaluation centers could alter the processes, speed, and safety standards used to review and approve new medical treatments.

• Over the long term, industry oversight and consumer protections may change as the agency shifts away from autonomous regulatory models toward closer alignment with the policy goals of the elected administration.

• The future direction and stability of national public health guidelines will likely be formalized in the coming weeks when a permanent FDA commissioner is nominated and undergoes the Senate confirmation process.
