Brief Summary:
BEAT7-001 is a single group study (supplementation). Using a multi-modal brain imaging portfolio, this study will assess whether brain energy metabolism (glucose and ketones), structure or functional connectivity change in older people with frontal glucose hypometabolism after 28 days on an oral dose of 1 g/kg/day of triheptanoin.

Condition or disease Intervention/treatment Phase
Frontal Lobe Hypometabolism Drug: POST Triheptanoin Phase 1 Phase 2

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 15 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description: The participant will receive THN treatment, compared to PRE supplementation condition.
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Brain Energy and Aging With Triheptanoin: The BEAT7 Study
Actual Study Start Date : April 2016
Actual Primary Completion Date : August 8, 2018
Actual Study Completion Date : August 8, 2018

Arm Intervention/treatment
Experimental: Triheptanoin
Participant will undergo POST Triheptanoin suppementation 1g/kg body weight for 28 days (dose gradually increased each week, starting at, 0.25, 0.5, 0.75 and then 1 g) separated in 4 doses (with eah meal and before night) after a control PRE supplementation imaging protocol.
Drug: POST Triheptanoin
The target daily dose of triheptanoin will be 1 g/kg/d, or approximately 70 g/d during 28±2 days. It will be divided into four daily doses, one of which will be consumed at each meal and one with an evening snack.
Other Name: POST THN

Primary Outcome Measures :
  1. Global Change in Brain Glucose Uptake [ Time Frame: 28±2 days ]
    Global change (average of cortex) in brain glucose uptake as measured by 18F-FDG PET scans PRE vs POST 28±2 days of supplementation

  2. Global Change in Brain Ketone Uptake [ Time Frame: 28±2 days ]
    Global change in brain ketone uptake as measured by 11C-acetoacetate PET scans

Secondary Outcome Measures :
  1. Change in Brain Volumes [ Time Frame: 28±2 days ]
    Structural imaging by T1-weighted MRI to measure brain volume

  2. Change in Cerebral Blood Flow [ Time Frame: 28±2 days ]
    change in cerebral blood flow measured by arterial spin labeling (ASL) and calculated using a one-compartment model (average cortex)
