Filter by:The aim of this study is to measure the availability of the PDE10A enzyme in Huntington disease gene expansion carriers (HDGECs) using the recently developed radioligand [18F]MNI-659. The study will be cross-sectional, examining HDGECs at different stages of the disease (pre-manifest, stage 1 and stage 2), in comparison with Healthy Controls (HCs). The HDGECs included in this study will be recruited from the large database of the REGISTRY (NCT01590589) or ENROLL-HD (NCT01574053) studies.
This is a multicenter, multinational, randomized, parallel-group, double-blind, placebo-controlled, dose range finding study to compare the efficacy and safety of different doses of pridopidine versus placebo in the treatment of motor impairment in Huntington's Disease (HD).
This observational study will establish a clinical baseline and measure changes over time in movement, thinking, behavior, brain imaging, blood and spinal fluid markers in subjects with early stage Huntington's disease. Participants enrolled in this study may be eligible to participate in a future planned study of stem cell therapy for Huntington's Disease (HD). In-person study visits occur at screening, baseline, and every 6 months thereafter for a minimum of 12 months, with interim phone call assessments.
We are the missing link in clinical trials, connecting patients and researchers seamlessly and conveniently using a mobile health platform to advance medical research. We make it easy for patients to contribute to research for medical conditions that matter most to them, regardless of their location or ability to travel.
According to above basic findings, it is important to confirm those results in clinic. In this branch, the investigators will use patient control analgesic (PCA) device to investigate the consumption of morphine for patients undergoing hepatic surgery. Preoperative and postoperative (before and after surgery) blood will be sampling (15cc/time) and y liver tissue (10mm3) will be harvested to measure the expression of above molecules (TM, IL-20, HD). Pain questionnaire will also be applied to evaluate their pain control quality. Certainly, the morphine consumption and results from pain questionnaire will be correlated with the molecule amount to figure out possible relationship between morphine consumption and those molecules. Patients undergoing abdominal surgery and using morphine pain control analgesia (PCA) device will be involved. Pre- and Post- operative (after anesthesia and at the end of surgery) blood sampling (total 30 ml) plus normal liver tissue (10mm3) e will be harvested. Above protein(TM, IL-20, HD) amount change will be measured (ELISA for TM, IL-20 (serum) or flowcytometry (white cells) for TM, HD, IL-20 expression, stain or blotting for skin tissue). Patients will be included in this branch to check the correlation between morphine consumption and protein expression. Pain questionnaire (BPI, McGill) will be applied for pain evaluation. 2-D gel analysis will also be applied to screen further possible molecules. Specific aims 1. To investigate the correlation of morphine consumption and the serum amount of IL-20, TM or HD 2. To investigate the relationship between IL-20, TM, HD amount in liver tissue and morphine consumption
The influence of bupropion compared to placebo on the change of apathy as quantified by the apathy evaluation scale (AES-I, where I [informant] is a friend or family member familiar with the daily activities of the subject) in patients with HD after ten (10) weeks of treatment.
The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of SD-809 extended release (ER) in participants switching from tetrabenazine to SD-809 ER. In addition, the safety and tolerability of long-term treatment with SD-809 ER will be assessed in "Switch" participants as well as "Rollover" participants completing a randomized, double blind, placebo-controlled study of SD-809 ER.
The hypotheses of the project are 1. Diffusion MRI using compressed sensing could have reduced motion sensitivity and improved susceptibility related artifact because of accelerated acquisition. 2. The macromolecule deposition in the brain of patients with Huntington Disease (HD) can lead to changes detectible by diffusion MRI. To validate the hypothesis that the new accelerated diffusion MRI technique could produce a new biomarker for HD, patients with Huntington Disease will be recruited. The diffusion index will be calculated using accelerated acquisition. The diagnostic performance will be evaluated for data reconstructed with and without acceleration. The correlation with the disease severity will be assessed.
The purpose of this project is to study the efficacy of an anaplerotic treatment on brain energy profile evolution at an early stage of the Huntington disease.
Huntington's disease (HD) is an incurable and fatal disorder characterised by progressive degeneration of the basal ganglia and the cerebral cortex. Contrary to earlier thinking, HD is associated with abnormalities in peripheral tissues which might even contribute to brain pathology including muscle wasting, mitochondrial abnormalities, and impaired muscle energy metabolism. Mitochondrial impairment and muscle atrophy in human HD patients and murine models of HD are associated with altered expression of PGC-1a, a transcriptional cofactor that seems to regulate many, if not all of the adaptations of muscle fibres to chronic endurance training, and induces improved exercise performance and increased peak oxygen uptake. We aim at investigating whether endurance exercise has the capability of stabilizing and / or reversing PGC-1a dependent alterations of muscle function and structure in HD patients, and whether muscle training ameliorates musculoskeletal and cardiovascular function, as well as motor and cognitive symptoms in HD patients.
