George Tidmarsh, head of the FDA's Center for Drug Evaluation and Research (CDER), has been placed on administrative leave amid an investigation into his personal conduct.
A lawsuit claims Tidmarsh abused his position to harm a former business associate, Kevin Tang, and Aurinia Pharma, a company in which Tang is an investor.
Tidmarsh believed the probe into his conduct was prompted by concerns he raised about a new fast-track programme for the rapid approval of some drugs.
