FDA Leadership Shakeup Sends Shockwaves Through Biotech Industry

The pharmaceutical and biotech sectors were rocked by the sudden departure of Peter Marks, the influential chief of the FDA's Center for Biologics Evaluation and Research (CBER). The news, which broke over the weekend, has sent ripples through the industry, causing significant market turbulence and raising concerns about the future of drug development and regulation in the United States.
Marks' Departure and Market Reaction
Peter Marks, widely regarded as a key figure in the FDA's biologics division, was reportedly forced out by new Health and Human Services Secretary Robert F. Kennedy Jr. The announcement led to a sharp decline in biotech stocks, with the S&P biotech index (XBI) dropping more than 5% on Monday. Major players like Gilead, AbbVie, and Amgen, as well as smaller companies such as Arcellx, Viking Therapeutics, and Summit Therapeutics, all felt the impact.
Vaccine manufacturers were particularly affected, with giants like Pfizer and Merck seeing notable declines. Companies specializing in biologics, including antibodies and cell therapies, also experienced significant market pressure.
Industry Response and Concerns
The news of Marks' departure has elicited strong reactions from industry leaders. Paul Hastings, CEO of Nkarta, expressed dismay on LinkedIn, stating, "We have been told over and over 'don't worry, RFK will not interfere with vaccines or reviewers at FDA.' Now he's crossed the red line on both." Nkarta's stock, which focuses on cell therapies for autoimmune disorders, fell from about $2 before the weekend to $1.79 on Tuesday morning.
Jeremy Levin, CEO of Ovid Therapeutics, warned of potential far-reaching consequences, saying, "This letter should shake us all. It signals that the very infrastructure we rely on to evaluate, approve, and monitor life-saving medicines—and to protect patients from harm—is at risk of collapse." Ovid's stock, already down 66% year-to-date, plummeted an additional 11% on Monday to 31 cents.
Implications for FDA Leadership and Policy
The resignation of Peter Marks has raised questions about the future direction of the FDA under the new administration. Marks' departure letter expressed concerns about the HHS Secretary's approach to vaccine safety and efficacy, stating, "It has become clear that truth and transparency are not desired by the secretary, but rather he wishes subservient confirmation of his misinformation and lies."
Adding to the uncertainty, reports emerged that newly appointed FDA Commissioner Marty Makary personally signed off on Marks' dismissal as his first official act. This development has heightened concerns about potential shifts in FDA policy and leadership.
Analysts are now speculating about the possibility of further departures among key FDA officials and the potential impact on ongoing regulatory processes. The situation has left many in the industry questioning what the "'new norm' of FDA will be," as noted by Guggenheim analysts.
