Health Condition(s) or Problem(s) studied
|
Huntington's disease MedDRA version: 18.0
Level: PT
Classification code 10070668
Term: Huntington's disease
System Organ Class: 10010331 - Congenital, familial and genetic disorders
|
Intervention(s)
|
Product Name: Triheptanoin Product Code: UX007 Pharmaceutical Form: Oral solution Pharmaceutical form of the placebo: Oral solution Route of administration of the placebo: Oral use
|
Primary Outcome(s)
|
Main Objective: the primary objectice is to evaluate the efficacy of triheptanoin in - increasing the energy response in the metabolic profile of the brain of early affected HD patients , as captured by 31-Phosphorus Magnetic Resonance Spectroscopy - slowing atrophy in the caudate of early affected HD patients as measured with volumetric resonance imaging
|
Primary end point(s): - an increase in the index of brain energy restoration as defined by the difference between Pi/PCr ration during visual stimulation and the mean of Pi/PCr ratio during rest and recovery using 31P-MRS after 3 months - a decrease in the rate of caudate atrophy, using volumetric MRI, after six months of treatment with triheptanoin in early HD patients
|
Secondary Objective: - to assess the clinical benefit of triheptanoin on motor function in HD patients using scores on the United Huntington's Disease Rating Scale - to assess the clinical benefit of triheptanoin on cognitive function ansd psychiatric symptoms in HD patients using scores on the symbol digit test, PBA-S and the HVLT-R - to assess the effect on quality of life (SF-36) of HD patients of therapeutic use of triheptanoin -to confirm long term clinical and biological tolerance of triheptanoin in HD patients - to evaluate long-term compliance with dietary modifications in HD patients - o look for correlations between neuroimaging volumetric parameters; brain energy profiles and clinical scores, beofre avec after treatment.
|
Secondary Outcome(s)
|
Timepoint(s) of evaluation of this end point: a) 6 months and 1 year of treatment b) 1 year c) 6 months and 1 year d) 1 year
|
Secondary end point(s): a) increase in the index of brain energy restoration using 31P-MRS b) decrease in the rate of caudate atrophy after 1 year of treatment with triheptanoin in early affected HD patient. c) the clinical benefit of triheptanoin will be evaluated by a decrease in the progression of the UHDRS over 6 months ans 1 year of treatment. d) it will be also evaluated using SMDT e) The benefit of triheptnaoin use on patient quality of life will be evaluated by using the SFR-36 f) long term compliance will be performed by regular bioclinical testing from blood abd urine samples g) Long term tolerance will be confirmed by clinical exam and by patient phone call h) changes in brain energy will be correlated with volumetric measures ans clinical rating scale scores.
