One Pivotal Trial, the New Default Option for FDA Approval — Ending the Two-Trial Dogma | NEJM This Sounding Board announces a new FDA policy that the default requirement for FDA approvals will be one robust pivotal trial plus confirmatory evidence, rather than two trials.

This is just needless, self-destructive, and problematic as regulatory policy. Also there never was and isn’t a two trial “dogma.” Bad headline, NEJM.

The Trump administration is turning drug review into make-a-deal “FDA decision-making may be reduced to a sequence of ‘make-a-deals’ with Trump, his FDA, or even political allies,” experts warn.

With the problematic national priority review voucher in the news again today (FDA staff not involved in decisionmaking? Really?), here’s our overview of how it opens the FDA up to corruption and moves us further and further away from “gold standard” reviews: www.statnews.com/2025/11/21/f...

I filed an amicus brief on behalf of 24 professors challenging the interim PTO director's illegal policy of blocking IPRs for any patent that is more than a few years old.

FDA publishes rejection letters sent to drugmakers, with a big caveat The FDA published more than 200 letters that it sent to companies when it rejected their medicines, but the letters came with a caveat.

<10% of these were not previously published (via STAT). Remember Sniglets? What term can we create for something that is self-promoted as a major step forward but is not really in reality even close to that?

Congress Should Remove The Rare Disease Carve-Out From Medicare Drug Price Negotiation, Not Expand It | Health Affairs Forefront Expansion of the Medicare drug price negotiation rare disease drug carve-out would unnecessarily limit the number of drugs eligible for negotiation, allow for continued high drug prices for products that earn billions of dollars in Medicare, and introduce a new set of misaligned incentives.

Language is now back in the Senate version of the OBBA that would undermine Medicare price negotiation for drugs with Orphan Drug Act designation. Here's our HA Forefront published yesterday (!) from Helen Mooney and @benro.me on why it is a very bad idea:
