Filter by:This study is to compare the pharmacokinetics of Dimebon in subjects with severe renal impairment to subjects with normal renal function after oral administration of a single oral 20-mg dose of Dimebon. This study is also to assess the safety and tolerability of a single oral 20-mg dose of Dimebon in subjects with severe renal impairment and subjects with normal renal function.
Huntington's disease (HD) is a slowly progressive disorder that devastates the lives of those affected and their families. There are no treatments that slow the progression of HD, only mildly effective symptomatic therapies are available.Creatine monohydrate is considered a nutritional supplement. The purpose of CREST-E is to test whether high-dose creatine can slow the progressive functional decline that occurs in persons 18 years or older with early clinical features of HD. The long-term safety, tolerability and effectiveness of up to 40 grams daily creatine compared to placebo is studied. A variety of biological processes are assessed for markers of disease activity or progression and creatine effects. Up to 50 active research centers globally will enroll 650 subjects.
The pace of basic science research defining the mechanisms of selective neuronal degeneration in Huntington disease (HD) has far exceeded the pace of translation of this information into clinically effective treatments for the disease. One reason for this bottleneck between bench and bedside is the paucity of available surrogate markers for HD. Identification of surrogate markers is critical for the design of future clinical trials. Such markers could provide a reliable signal of early brain dysfunction in HD and could be used as a biomarker in trials of agents that could prevent onset or delay progression of disease. Frontal-subcortical networks are known to be affected in HD and contribute to the cognitive dysfunction characteristic of the disease. Quantitative EEG (QEEG) can be used to assess the integrity of this circuitry; characteristic QEEG abnormalities long have been known to be present in the early stages of the illness (Bylsma et al., 1994). More recent research has suggested that a comprehensive topographic approach to QEEG analysis may reveal additional changes in brain activity (Bellotti et al., 2004) that may be indicative of subclinical disease (de Tommaso et al., 2003). This proposal aims to determine whether quantitative EEG techniques can be used to identify HD-specific abnormalities and thus serve as surrogate markers of disease. The goals of this pilot project are three-fold. First, we will determine if there are QEEG differences between normal control subjects and those with mild or moderate HD. Second, we will examine associations between severity of HD and the QEEG differences detected and determine if these QEEG differences are present when comparing the least affected HD subjects and normal controls. Third, we will examine associations between QEEG variables of interest and other clinical variables, including age of onset of symptoms, number of CAG repeats, severity of motor and behavioral symptoms as measured by the Unified Huntington Disease Rating Scale (UHDRS) subscores, and severity of cognitive impairment as measured by the cognitive subscore of the UHDRS and Mini-Mental State Examination (MMSE).
The purpose of this study is to determine if ACR16 is effective and safe in the symptomatic treatment of Huntington's disease.
To determine if memantine in doses of 10 mg BID affects memory, cognition, and behavior in patients with Huntington's disease (HD).
The goals of this trial are to determine if coenzyme Q10 is effective in slowing the worsening symptoms of Huntington's disease and to learn about the safety and acceptability of long-term coenzyme Q10 use by determining its effects on people with Huntington's disease.
This study will evaluate the safety of 3 months of Dimebon dosing and the efficacy of Dimebon in improving cognitive, motor, and overall function in subjects with Huntington's Disease.
This study will examine the ways in which people reveal their status as a carrier of Huntington s disease (HD) or of being at risk for the disease. It will explore factors that influence decisions about disclosure and how disclosure is made to family members, partners, and close friends. HD is an inherited, progressive disease. It causes nerve degeneration, motor disturbance, loss of awareness, and psychiatric symptoms. Currently, no effective treatment is available to prevent or delay HD progression. The mean age of onset is 35 to 44 years, and the median survival rate after onset is 15 to 18 years. HD affects about 1 in 10,000 people in the United States, so about 30,000 have HD and more than 200,000 are at risk. Predictive testing for HD has been available since 1993. It can be a life-changing event to learn of being at risk for HD. Disclosure has been studied among people with HD and other diseases, but knowledge about the extent of nondisclosure and disclosure is limited. There is evidence that a person s psychological adaptation to AD may be a factor. Adaptation involves processes that help a person search for meaning in what has happened, attempt to gain control of his or her life, and improve self-esteem in light of the threatening situation. Participants ages 18 and older who have had a positive genetic test result more than 6 months earlier regarding HD or who have a family history of HD but no predictive testing and who do not have symptoms of HD may be eligible for this study. Recruitment is done through HD clinics, support groups, and online websites and mailing listservs. About 260 people will be in the study. Participants will complete a survey taking 30 to 40 minutes to do. Two survey versions are available: for those who are gene carriers and for those at risk. Participants are asked to complete the version applying to them. The survey can be done online or through a hard copy to complete at home and send to NIH. This survey is anonymous. Participants will list the adults with whom they have a relationship and up to 10 people they interact with. They will indicate those who know about the HD gene or risk status. They will also list those to whom they have personally made disclosure. The goal is to distinguish if knowing the status or the act of disclosure is more important. Questions also involve discussing the inheritance and features of HD, and participants feelings or concerns about HD gene or risk status. Participants will be asked about their first disclosure experience, most recent experience of it, and timing of disclosure the time between learning of HD status and telling another person about it. There are also questions on decisions of nondisclosure, negative and positive aspects of disclosure for participants, and what health care professionals can do to help participants disclosure decisions.
This study is being conducted to determine the safety and tolerability of Dimebon in people with Huntington's disease after short-term exposure (one week) and after longer exposure (three months). Also, the study will assess whether or not there is an effect of Dimebon on the symptoms of Huntington's disease, including cognitive (thinking abilities), motor (movement), behavior, and overall functioning.
The primary objective of this study was to establish the absolute reduction of chorea in participants with Huntington's disease(HD) treated with tetrabenazine or placebo
