FDA leadership turmoil deepens after more exits

The US Food and Drug Administration was thrown into deeper uncertainty on Friday after the departures of the acting heads of its drugs and biologics centers, along with chief of staff Jim Traficant, days after commissioner Marty Makary resigned.

Tracy Beth Høeg, who had served for around six months as acting director of the Center for Drug Evaluation and Research, said on X that she had been fired after declining to resign. Katherine Szarama, who had held the acting director role at the Center for Biologics Evaluation and Research for only 10 days, is also leaving the agency.
