Extended summary

Published: 04.11.2025

Introduction

Dr. George Tidmarsh, the head of the Food and Drug Administration's (FDA) drug center, has resigned following an investigation into serious allegations regarding his personal conduct. This abrupt departure, which occurred shortly after he was placed on leave, highlights ongoing issues within the FDA's leadership and raises concerns about the agency's operational integrity.

Details of the Resignation

Dr. Tidmarsh's resignation was confirmed by Emily Hilliard, a spokesperson for the Department of Health and Human Services (HHS). The investigation into his conduct was initiated by the Office of General Counsel, prompting his leave on Friday and subsequent resignation on Sunday morning. Hilliard emphasized that Secretary Kennedy demands high ethical standards from all personnel and is dedicated to maintaining transparency within the agency.

Legal Challenges and Allegations

Compounding the situation, Aurinia Pharmaceuticals, a company linked to Tidmarsh's previous business associations, has filed a lawsuit against him. The lawsuit claims that Tidmarsh made "false and defamatory statements" while serving at the FDA, alleging that he harbored a personal vendetta against Kevin Tang, the chair of Aurinia's board. The lawsuit suggests that Tidmarsh's actions were influenced by past grievances stemming from their shared history in pharmaceutical companies, where Tidmarsh held executive roles.

Background of Dr. Tidmarsh

Before his appointment to the FDA in July, Tidmarsh had a lengthy career in the pharmaceutical and biotech sectors in California, where he founded and led several companies. He also served as an adjunct professor at Stanford University. His recruitment to the FDA followed discussions with FDA Commissioner Marty Makary, indicating a significant expectation for his leadership role within the agency.

Impact on the FDA

Dr. Tidmarsh's departure is part of a broader trend of instability within the FDA, which has seen numerous leadership changes and controversies in recent months. This includes the resignation of Dr. Vinay Prasad, who was under scrutiny from conservative activists but returned to the agency shortly after. The FDA's drug center, overseen by Tidmarsh, has experienced a significant loss of personnel, with over 1,000 staff members leaving in the past year due to layoffs and resignations.

Public Comments and Controversy

In September, Tidmarsh drew attention for a controversial LinkedIn post in which he publicly criticized a kidney drug produced by Aurinia Pharmaceuticals, stating it had not demonstrated a direct clinical benefit. This unusual public commentary from an FDA regulator led to a sharp decline in Aurinia's stock, resulting in a loss of over $350 million in shareholder value. Tidmarsh later removed the post, asserting it was made in a personal capacity rather than in his official role.

Conclusion

The resignation of Dr. Tidmarsh underscores ongoing challenges faced by the FDA, particularly in maintaining leadership stability and public trust. As the agency grapples with internal and external pressures, this incident may prompt calls for greater oversight and reform within its operations. The legal implications of Tidmarsh's actions and the subsequent lawsuit from Aurinia Pharmaceuticals could further impact the agency's reputation and operational effectiveness in the pharmaceutical sector.
