Active clinical trials for "Huntington Disease"

The proposed study is a double-blind, placebo controlled pilot study of HD, PD, and DLB subjects with sleep disturbances. This study is designed to determine the effects of 4 weeks Ramelteon treatment on the sleep patterns of people with basal ganglia disorders such as HD, PD and DLB. The study also aims to look at the sleep patterns of caregivers of people with HD, PD and DLB.

Empathy, defined as the ability to understand others emotions, is a fundamental concept in social interactions. It is a psychological phenomenon involving various separable components : (i) the ability to feel and imagine the emotions, (ii) the ability to adopt the perspective of other people. Several neurological diseases with behavioral disorders may lead to impaired processing of social and/or emotional informations. These pathologies are likely to induce a lack of empathy that may result from impairments at different levels. The objective is simply to study how others' emotions are understood and how this allows for regulation of personal behavior. This study is being carried out among patients seen for various health problems and who can make behavior changes. This study could help to understand some neurological diseases and thereby to identify them earlier and/or to better differentiate them.

AIM: To assess synaptic density and to investigate the potential relationship of regional synaptic loss with motor and non-motor symptoms and with disease progression in the human brain in vivo in patients with HD. DESIGN: The investigators will include 20 HD mutations carriers and 15 healthy controls. All subjects will undergo a clinical examination, with comprehensive assessment of motor and non-motor symptoms, and imaging evaluation consisting of 11C-UCB-J PET-CT and 18F-FDG PET-MR at baseline and after 2 years.

The underlying goal of this study is to assess [123I]MNI-420 SPECT imaging as a tool to detect A2aR density in the brain of PD and HD research participants to be compared with similarly aged healthy subjects.

The role of disorders of socio-emotional processes in cerebral diseases such as Alzheimer's disease, frontal temporal dementia, Parkinson's disease, Huntington's disease, traumatic brain injury, stroke, focal lesions, has been recognized recently. Social cognition refers to a large group of emotional and cognitive abilities regulating inter-individuals relationships and it includes mainly theory of mind, emotional information processing and empathy. However, assessment of socio-emotional processes is still largely based on experimental tests that are not validated for clinical purpose. In addition their long duration of administration is not adapted to clinical examination. Finally these tests have not been standardized and normalized in French-speaking population.

This study will evaluate four different modified release formulation to estimate the amount of dimebon available to the body relative to the current dimebon formulation that is given three times a day. The results of this study will help inform and guide further formulation development efforts with the ultimate goal of reducing dose frequency to once-a-day or twice-a-day.

This drug-drug interaction study is being conducted to evaluate the potential effect of Dimebon on the pharmacokinetics on dextromethorphan, a probe substrate of the cytochrome P450 2D6 (CYP2D6) enzyme, after multiple dose administration to healthy adult subjects.

The study drug, GSK356278, is a possible new medicine for the treatment of Huntington's disease. Huntington's disease, which is often called HD, is caused by a faulty gene that is passed down through families. HD causes damage to nerve cells in the brain which causes them to waste away. As the damage progresses patients develop symptoms that affect every aspect of life. HD reduces people's ability to walk, talk, think, communicate and causes uncontrolled movements. GSK356278 may slow down the progression of damage to nerve cells in people with HD and help with their ability to think. GSK356278 was well tolerated when it was given as a single dose to healthy people. In this study we want to see what effects, both good and bad, GSK356278 has in people when it is taken every day. During the study we will look at about 3 different doses of GSK356278 in about 36 healthy people. The study will also look at how GSK356278 tablets behave in the body after it is swallowed (this is called pharmacokinetics). The study will also look at effects of GSK356278 on the body (this is called pharmacodynamics). The study will help to design future clinical studies with GSK356278.

The death of brain cells in Huntington Disease (HD) is thought to be associated with a lack of normal cell energy and harmful brain substances called free radicals. Coenzyme Q10 (CoQ) is a marketed nutritional supplement that may prove useful in HD because it increases cell energy and combats free radicals. Most studies of CoQ have looked at only one formulation of CoQ ("ubiquinone") in HD. The purpose of the study is to find out if people that switch from the common formulation of CoQ ("ubiquinone") to a different formulation ("ubiquinol") have higher levels of CoQ in their blood after taking the same dose. The investigators also want to find out if this different formulation is tolerable for individuals with HD.

The study is designed as a multi-site, prospective, 15-month longitudinal, cohort study measuring CSF mHTT in participants with early manifest Stage I or Stage II Huntington's Disease (HD).
