Fresh frozen plasma, the liquid part of blood stripped of red and white cells, may hold the key to saving more lives after traumatic brain injury. The U.S. Department of Defense has been funding research on this for over a decade. While significant studies remain in operation and, therefore, a comprehensive review cannot yet be reported, the results are increasingly hard to ignore.
The most significant step forward is the FIT-BRAIN Trial, a federally funded study that began enrolling patients in early 2024 across eight U.S. trauma centers. Researchers at Northwestern University, backed by the Pentagon’s Congressionally Directed Medical Research Program, are testing whether plasma given soon after a severe brain injury can limit damage and improve survival. (The trial targets 357 patients, with results expected around 2027.)
Other recent studies have already built the case. A January 22, 2025 paper in the Annals of Surgery journal, driven by federally-funded studies, found that patients given cold-stored platelets after brain injury needed emergency skull surgery 14 percent less often and a 2025 analysis of nearly 15,000 children with severe brain injuries found that plasma given within four hours cut early death risk by nearly half.
In Fiscal Year 2025, Congressionally Directed Medical Research Programs funding was cut 57%, to $650 million, with Traumatic Brain Injury and Psychological Health Research Programs receiving zero dollars for new research grants. Recently, FY2025’s financial research crisis was partially resolved. On February 3, 2026, President Trump signed the Consolidated Appropriations Act, 2026 (P.L. 119-75), restoring CDMRP funding to $1.27 billion across 34 research programs.
