NCT04137692
Pathogenic mutations of the brain glucose transporter type I lead to glucose transporter deficiency syndrome (G1D), which is most often associated with medication-refractory epilepsy and movement dysfunction. At present, G1D is only alleviated by interventions such as the ketogenic diet, which can be poorly tolerated and afford only an incomplete restoration of neural function. A better understanding of G1D can uncover new fundamental aspects of brain function while facilitating the development of new therapies aimed to restore brain metabolism and excitability. We will conduct a mechanistic trial that will utilize a mechanism-testing framework broadly applicable to metabolic interventions. The trial will investigate red blood cell exchange (i.e., the replacement of human G1D circulating red cells, which are deficient in GLUT1) with healthy donor cells as a novel means to augment blood-to-brain glucose transport. The hypothesis is that electroencephalography post treatment will display an increase in beta brain activity. Additional measures of brain activity will also be secondarily tested.
NCT02013583
The purpose of this protocol is to create a registry for patients diagnosed with Glucose Transporter Type 1 Deficiency (G1D), or patients experiencing symptoms consistent with G1D but not yet diagnosed, to enter medical information for physicians and other health researchers to analyze to increase the understanding of G1D and any sub-diagnoses.
NCT03202108
Acceptability study to evaluate the gastrointestinal tolerance, palatability and participant compliance, over a 7-day period, of Krio for the dietary management of participants with intractable epilepsy or Glut-1 deficiency syndrome patients on a ketogenic diet.
NCT03041363
To determine the maximum tolerated dose (MTD), as a percentage of calories consumed, of triheptanoin (C7 oil; C7) in a pediatric and adult patient population genetically diagnosed with glucose transporter type 1 deficiency disorder (G1D).
NCT01993186
The primary objectives of the study are to evaluate the efficacy of UX007 compared to placebo as measured by the reduction from randomization to Week 8 in frequency of seizures and to evaluate the safety of UX007 via adverse event (AE) rates, laboratory values, and electrocardiogram (ECG).
NCT02018315
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.
NCT02021526
This is a single-site, open-label, phase II trial of C7, a food supplement or medical food, for the development of treatment outcome measures for glucose transporter type I deficiency (G1D). The primary outcome measures are: 1. Safety and tolerability of C7 as measured by changes in comprehensive blood work, including lipid and free fatty acid panels, self-reported side effects and clinical exam; 2. Changes in brain metabolic rate by MRI and EEG measurements during C7 treatment; and 3. Maintenance of ketosis in G1D patients on ketogenic diet, as measured by serial ketone levels during treatment initiation.
