NCT03971123 · Phase 1 · COMPLETED
Study to Compare the Pharmacokinetics of Tricaprilin Formulations and a Placebo on Ketone Body Production
This trial tests whether different formulations of tricaprilin — a compound derived from a type of fat called medium-chain triglycerides — produce different levels of ketones in the blood. Ketones are an alternative fuel source the brain can use. This is a Phase 1 trial, meaning it is focused on how the drug behaves in the body, not whether it helps Alzheimer's. It enrolled only healthy young men to measure absorption and metabolism across formulations.
