About this trial
The purpose of this study is to evaluate the effects of tricaprilin (20 g twice a day) on cognition, global function, activities of daily living, resource utilisation, safety, and tolerability, in participants with mild to moderate AD dementia.
This is a randomised, double-blind, placebo-controlled, parallel-group, multi-centre design in up to 535 participants.
