Newly Published Study Quantifies Types of Grants Terminated by NIH Since Late February

A new research letter in JAMA “quantified the number and corresponding funding amounts of terminated NIH grants overall and by institute or center and award type” between February 28 and April 8, 2025.

Between those two dates, “694 NIH grants were terminated across 24 of the 26 institutes and centers (including the Office of the Director) that administered active NIH grants.” The cumulative amount of terminated grant funding was “$1.81 billion, of which $544,024,077 (30.0%) had not been expended at the time of grant termination.”

The largest number of terminated grants was “administered by the National Institute of Mental Health…and the National Institute on Minority Health and Health Disparities [NIMHD].” The dollar amount of terminated grant funding was “highest for the National Institute of Allergy and Infectious Diseases and the NIMHD.” Across the 694 terminated grants, 57.6% were research project grants.

The proportion of “terminated grant funding was higher than the proportion of grants terminated across most institutes and centers, suggesting that larger-than-average grants were more likely to be terminated.” 20% of terminated grants were “formal training, fellowship, or career development awards.”
