Despite massive turnover and internal dysfunction at the FDA, biotech investors have largely shrugged off the regulatory uncertainty. This disconnect suggests the market believes the negative impacts, like drug review delays, are a lagging indicator that won't materialize immediately, creating a potential future risk for the sector.

An ideologically driven and inconsistent FDA is eroding investor confidence, turning the U.S. into a difficult environment for investment in complex biologics like gene therapies and vaccines, potentially pushing innovation to other countries.

The 'FDA for AI' analogy is flawed because the FDA's rigid, one-drug-one-disease model is ill-suited for a general-purpose technology. This structure struggles with modern personalized medicine, and a similar top-down regime for AI could embed faulty assumptions, stifling innovation and adaptability for a rapidly evolving field.

Abivax's drug has a novel, not fully understood mechanism (miR-124). However, analysts believe strong clinical data across thousands of patients can trump this ambiguity for doctors and regulators, citing historical precedents like Revlimid for drugs that gained approval despite unclear biological pathways.

Unlike a drug that can be synthesized to a chemical standard, most vaccines are living biological products. This means the entire manufacturing process must be perfectly managed and cannot be altered without re-validation. This biological complexity makes production far more difficult and expensive than typical pharmaceuticals.

Using safety and preliminary efficacy data from its lead drug for MPS1, Immusoft successfully requested an FDA waiver for definitive toxicology studies for its next program in MPS2. This platform approach saves significant time and capital, accelerating the entire pipeline without 'reinventing the wheel'.

The replacement of CEDAR Director Richard Pazder with Tracy Beth Hoeg, who is viewed as an ideologue lacking regulatory experience, signals a shift toward politically driven decisions at the FDA. This move creates significant uncertainty and raises concerns that ideology, not science, will influence drug approvals.

Industry sentiment on the FDA is not monolithic. A recent survey reveals that while biotechs largely maintain confidence in the agency's hardworking staff and their day-to-day interactions, there is deep concern and a lack of trust in the agency's top leadership. This nuanced view highlights that the perceived problems are rooted in politicization and leadership competence, not frontline operations.

Diseases like Ebola and malaria, which primarily affect poor countries, lack market incentives for vaccine R&D. The Ebola vaccine only progressed because it was briefly on a U.S. bioterrorism list created after 9/11, highlighting how market failures require creative, sometimes accidental, incentives to overcome.
