Proposed White House regulations could kill 5,000 clinical trials, analysis finds

The Trump administration is mulling new rules that would give political appointees final say on research grants

Nearly 5,000 clinical trials, including 1,000 cancer treatment tests, face termination under proposed federal regulations , a new analysis by science advocacy group Stand Up for Science finds. The potential cuts would also affect hundreds of pediatric, veteran health and heart disease trials, according to the report.

The trials are at risk because of a rule proposed by the White House’s Office of Management and Budget (OMB) in May that would give political appointees the final word on federal research grants across agencies—a departure from years of relying on scientific peer review to judge grants’ merits. The proposed rules are aimed to combat “a ‘woke’ policy agenda” and to curb international collaboration, according to a statement published in the Federal Register . The OMB is headed by Russell Vought , the lead architect of the Heritage Foundation’s Project 2025 plan for the Trump administration.

Clinical trials are the final stages for testing new medical treatments and interventions, and they can involve dozens to thousands of volunteer patients, depending on the trial’s aims. A 2025 JAMA Internal Medicine analysis of 383 clinical trials associated with grants terminated by the Trump administration found that as many as 74,000 patients were affected by the cuts.

Applying the proposed rules to some 10,000 clinical trials currently being funded by the National Institutes of Health, Stand Up for Science found that nearly half would face termination. Many of these are international in nature or could trip a list of more than 350 “banned words” —phrases that Pen America, a free speech group, reports that federal agencies have either sought to prohibit or limit, according to the new analysis. Words on the list include “abortion,” “solar power” and “vaccines”.

“People’s lives are on the line. These are clinical trials of new drugs and interventions that could change people’s lives,” said Stand Up for Science founder Collette Delawalla in a statement.
