Study Overview
Brief Summary
The purpose of this study is to determine safety, tolerability, and pharmacokinetics/dynamics of a ketogenic dietary supplement containing medium chain triglycerides (MCTs) in patients with Alzheimer disease (AD). Novel imaging and laboratory biomarkers in response to this intervention will also be explored.

Arms & Interventions
Ketogenic medium chain triglyceride drink
Lactose-free skim milk drink containing 25 g of MCT oil per 250 ml.
Intervention: Ketogenic medium chain triglyceride drink (MCT drink) (Dietary Supplement)
Placebo
Lactose-free skim milk drink containing high-oleic sunflower oil in the equivalent amount of energy as the active arm.
Intervention: Placebo (Dietary Supplement)
Outcomes
Primary Outcomes
Number of participants with adverse events, serious adverse events
Time Frame: From baseline to day 10 of intervention
Plasma ketone concentrations in response to ascending dose of MCT
Time Frame: Day 10 of intervention at 0.5, 1, 1.5, 2, 3, 4, 4.5, 5, 5.5, and 6 hours post MCT dose
Plasma ketone concentrations of betahydroxybutyrate (BHB) and acetoacetate (AcAc) will be measured in response to MCT dosing from 10-50 grams daily.
Secondary Outcomes
- Area under the plasma concentration versus time curve (AUC) of MCT(Day 10 of intervention at 0.5, 1, 1.5, 2, 3, 4, 4.5, 5, 5.5, and 6 hours post MCT dose)
