CA Cycle in the Dentate in Friedreich's Ataxia

ClinicalTrials.gov Identifier: NCT03122925 First received: April 18, 2017

OBJECTIVE: To measure the tricarboxylic acid (TCA) cycle rate in the dentate nucleus in a group of control subjects and subjects with Friedreich's Ataxia (FRDA).

HYPOTHESIS: The TCA cycle rate will be lower in FRDA subjects than in controls APPROACH: We will infuse carbon-13 (13C) labeled glucose and measure the rate of 13C label incorporation from glucose to glutamate in the brain using in vivo magnetic resonance spectroscopy.

Detailed Description:

We will measure the TCA cycle rate in the dentate nucleus in a group of FRDA patients and in a group of age-matched healthy controls using 13C MRS in vivo together with systemic i.v. infusion of 13C-labeled glucose.

We aim to obtain adequate data in 16 subjects grouped as follows:

n=4 pilot subjects (healthy subjects) for testing and optimization of the experimental setup.
n=6 healthy controls
n=6 FRDA patients
