The lengthy timelines of drug development create a significant perception lag for AI's impact. Molly Gibson clarifies that molecules currently in clinical trials were designed years ago using nascent AI models. The true capabilities of today's more advanced AI platforms won't be evident in approved drugs for several more years.

Despite significant layoffs and leadership changes early in the year that caused delays, the FDA dramatically increased its output, approving nearly twice as many drugs in the second half of 2025 as the first. This suggests the agency adapted and found a new, more efficient footing after an initial period of disruption.

While political drama at the top of the FDA captures headlines, the agency's rank-and-file reviewers are largely maintaining operational continuity. Many drug programs are still receiving necessary feedback within expected timeframes, suggesting the core machinery of the FDA is resilient.

In a striking reversal from 2024, large European pharmaceutical companies secured 13 FDA approvals while their eight largest US counterparts received only four. No single US company had more than one new drug approval, highlighting a significant performance gap and a potential shift in R&D pipeline productivity between the two regions.

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.

Unpredictable changes in FDA review processes are more destructive to biotech investment than consistently high approval standards. Investors can adapt to a stringent but stable regulatory bar, but constant changes undermine the multi-year planning and capital commitment required for drug development, causing investors to flee.

Despite widespread concern about political disruption at the FDA, key metrics for innovation in new drug approvals—such as first-in-class drugs and new targets—were almost completely flat in 2025 compared to previous years. This suggests the core regulatory engine has remained consistent, for now.

The resignation of key figures like Peter Marks triggered a cascade of departures, leaving the FDA with a significant loss of long-term institutional knowledge. This creates uncertainty around the execution of new policies and guidance for the biopharma industry.

Following the exit of controversial CBER director Vinay Prasad, the FDA approved several drugs that might have struggled under his tenure. This suggests a potential shift towards more regulatory flexibility, possibly influenced by political pressure ahead of midterm elections, creating opportunities for sponsors with controversial applications.
