Eli Lilly and Company (NYSE: LLY) stock traded at $851.12 in pre-market hours on October 8, 2025, up 0.66%, after closing at $845.72.
The pharmaceutical giant announced the appointment of Peter Marks, former head of the U.S. Food and Drug Administration’s (FDA) Center for Biologics Evaluation and Research (CBER), as Senior Vice President of Molecule Discovery and Head of Infectious Disease.
Marks’ appointment comes six months after his exit from the FDA, where he clashed with U.S. Health Secretary Robert F. Kennedy Jr. over vaccine policies. At the FDA, Marks played a central role in overseeing biologics and vaccines, including the approval of the first COVID-19 vaccines.
🚩Peter Marks joins Eli Lilly, proving the revolving door never stops turning
Another ex-FDA official jumps into bed with Big Pharma. He dismissed safety concerns and promoted the products he approved — proof that institutional corruption is rewarded, not punished.

Marks’ Transition From Regulator to Research Leader
Marks’ move marks another example of FDA experts transitioning into private industry roles. His deep regulatory experience and vaccine background are expected to bolster Eli Lilly’s research and development arm.
During his 13-year tenure at the FDA—nine of which were spent leading CBER—Marks was instrumental in guiding biologics research. His remarks at the Jefferies London Healthcare Conference had hinted at potential conflict under RFK Jr.’s administration, and his predictions materialized soon after.
Eli Lilly said in a statement that Marks’ expertise will accelerate innovation in vaccine discovery and strengthen its infectious disease pipeline. The company expects his leadership to advance molecule discovery efforts across therapeutic areas.
Ex-FDA Hires Strengthen Eli Lilly’s Scientific Team
Marks joins Racheal Anatol, another ex-FDA official who became Associate VP of Global Regulatory Policy and Strategy for Genetic Medicine in September. Anatol, like Marks, departed the FDA after internal disputes, signaling a broader shift of regulatory talent into corporate pharmaceutical research.
These appointments underscore Eli Lilly’s strategic focus on regulatory expertise to streamline approvals and strengthen compliance across its expanding drug portfolio.
