Treatment Development for Glucose Transporter Type I Deficiency Syndrome (G1D)
Clinical Trial of Citric Acid Cycle Stimulation in Energy-deficiency States: Treatment Development for Glucose Transporter Type I Deficiency Syndrome (G1D) (NMTUT 2010B)
The purpose of this trial is to determine if an alternative energy source will impact brain metabolism in a disorder characterized by glucose metabolism failure in the brain.
The central hypothesis tested in this investigation is whether circumventing impaired glucose metabolism is feasible, safe and potentially promising by supplying anaplerotic precursors through metabolism of odd-carbon fatty acids that can enter the citric acid cycle (CAC) through alternative metabolic pathways.

Genders Eligible for Study
Description
Inclusion Criteria:
- Male or Female
- Ages 1 month to <21 years of age
- Diagnosed with glucose transporter type I deficiency.
- Age matched (within 1 year) controls not diagnosed with G1D.
Exclusion Criteria:
- All subjects carrying body metal implants incompatible with the exposure to a magnetic field
- Subjects unable to tolerate the MRI and MRS procedures due to anxiety
- Subjects receiving oxygen supplementation or those confined to a bed or stretcher
- Subjects currently receiving a ketogenic diet, due to a high risk of seizure recurrence while transitioning off ketosis.
- Patients behaviorally unable to hold still for imaging procedures (rather than limited by seizure activity) will be excluded.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Triheptanoin
Triheptanoin (C7 oil, liquid) dosed at 1 g/kg body weight divided and administered 4 times per day via mouth or g-tube for 3 months.
|
Triheptanoin is a 7-carbon medium chain triglyceride

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants With Reduction in Spike-wave Fraction of the EEG Recording Time
Time Frame: 1 day
|
Visual analysis of EEG recording to determine the fraction of spike-range within the area of recording.
|
1 day

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants With Change in Brain Metabolic Rate After 3 Months
Time Frame: 3 months
|
Magnetic Resonance Imaging (MRI) used to calculate brain metabolic rate.
Brain metabolic rate compared before oil ingestion (Baseline), 90 minutes after oil ingestion, and after 3 months of daily oil ingestion in each participant.
Triheptanoin metabolism may lead to increased oxygen consumption only while the brain undergoes a reduction of ictogenesis.
We hypothesize that when ictogenesis is abolished by triheptanoin or absent at baseline, triheptanoin exerts little or no effect on CMR02.
