Can a vitamin B1 boost protect Babies' brains after severe infection?
NCT ID NCT07868679
First seen Oct 09, 2026 · Last updated Oct 09, 2026
Summary
Researchers are testing whether adding intravenous thiamine to standard treatment helps infants with meningitis or bacteremia develop better thinking and learning skills. The trial enrolls 240 infants up to 12 months old who show signs of these infections. Half receive thiamine once daily for three days plus standard care, and half receive a placebo plus standard care. The main goal is to compare cognitive development scores at 18 months of age.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- thiamine hydrochloride, a form of vitamin B1, given intravenously alongside standard treatment
- What this could lead to
- If it works, thiamine could become a low-cost addition to standard care that helps protect brain development in infants recovering from serious infections.
- What could go wrong
- This is a mid-stage trial, so the approach may not improve neurodevelopment. Infants in the study still receive standard care, and thiamine is generally well tolerated, but any added benefit is unproven.
