How a Controversial Critic Returned to a Key FDA Role—And Why It Matters

The Reappearance That Raised Eyebrows
A lightning rod rejoins the FDA's biologics division
Vinay Prasad, the oncologist and vocal FDA critic, is back at the Center for Biologics Evaluation and Research (CBER)—less than two years after leaving. His return to the agency’s biologics division, confirmed by HHS officials, surprised observers who remember his sharp critiques of drug approvals during the pandemic.
Prasad’s reappointment isn’t just bureaucratic shuffling. It signals a shift in how the FDA may evaluate emerging therapies, particularly mRNA vaccines and gene therapies. His skepticism of accelerated approvals and demands for robust clinical data now carry institutional weight.
Who Controls the Future of Biologics?
CBER’s quiet power over cutting-edge medicine
CBER oversees biologics: complex medicines derived from living systems, like mRNA vaccines, CRISPR therapies, and monoclonal antibodies. Unlike traditional drugs, these often target diseases at the genetic or cellular level.
The center’s decisions directly impact companies like Vertex, which relies on CBER to approve its next-generation gene therapies for sickle cell disease. Prasad’s role here—previously as a senior advisor, now in a yet-undefined position—could tilt the balance between innovation and caution.
Speed versus rigor isn’t an abstract debate. During COVID-19, CBER greenlit mRNA vaccines in record time. Prasad argued some decisions prioritized urgency over evidence. Now, he’s inside the room where those calls are made.
The Prasad Effect: How One Critic Shapes Policy
Prasad’s influence stems from his ability to dissect clinical trials publicly. His 2023 critique of an Alzheimer’s drug approval, for example, dissected statistical cherry-picking in phase 3 data. Such analyses made him a hero to evidence-based medicine advocates—and a thorn to pharma companies.
At CBER, his focus will likely extend to post-market surveillance. He’s long argued that accelerated approvals often lack follow-up studies to confirm benefits. If he pushes for stricter enforcement, companies may face heavier burdens to keep drugs on the market.
But there’s a tension. Overcaution could delay treatments for deadly diseases. Prasad’s return coincides with Vertex’s application for a CRISPR-based sickle cell therapy. How CBER handles it will test his practical impact.
Why This Moment Matters
Biologics are eating the drug development world
In 2024, biologics accounted for 40% of new FDA approvals, up from 25% a decade ago. Their complexity—and potential—makes oversight uniquely high-stakes. A single gene therapy can cost millions and alter DNA permanently.
Prasad’s return also reflects a broader FDA reckoning. The pandemic forced rapid decisions, but some, like the controversial approval of aducanumab for Alzheimer’s, drew backlash. The agency now walks a tightrope: encouraging innovation while restoring public trust.
HHS officials emphasize Prasad’s ‘methodological rigor.’ Critics whisper about politicization. Neither side disputes that his presence will change CBER’s internal debates.
What Comes Next
Watch two immediate pressure points. First, Vertex’s sickle cell therapy, which could set precedents for CRISPR approvals. Second, Moderna’s next-generation mRNA vaccines, now in late-stage trials.
Longer-term, Prasad’s tenure may hinge on a philosophical question: Can a skeptic reform the system from within? His allies hope he’ll enforce higher evidence standards. Opponents fear gridlock.
One thing’s certain. The biologics revolution won’t pause for debate. As treatments grow more powerful, so do the consequences of getting oversight wrong—or right.
