An open-label extension study of the HORIZON protocol evaluating the safety of dimebon (latrepirdine)in subjects with Huntington disease.
Active, not recruiting
Published on BioPortfolio: 2010-07-15T17:00:00-0400
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 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 ...
The purpose of this study is to determine if Dimebon is safe and effective for the treatment of cognitive impairment in Huntington disease.
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...
To estimate the absorption, safety, and tolerability of a dimebon transdermal solution relative to the dimebon immediate release oral formulation.
Different oculomotor abnormalities have been reported to occur in premanifest Huntington's disease. The aim of this study is to investigate which oculomotor items of the Unified Huntington's Disease R...
Lowering the levels of disease-causing proteins is an attractive treatment strategy for neurodegenerative disorders, among which Huntington's disease is an appealing disease for testing this strategy ...
In Huntington's disease, 60% of the variance in onset age is not explained by the huntingtin gene mutation. Huntington's disease onset was earlier in caffeine users.
Huntington's disease (HD) is a fatal progressive neurodegenerative disease characterized by chorea, cognitive impairment and psychiatric symptoms. Retinal examination of HD patients as well as in HD a...
Family functioning in Huntington's disease (HD) is known from previous studies to be adversely affected. However, which aspects of family functioning are disrupted is unknown, limiting the empirical b...
A biochemical phenomenon in which misfolded proteins aggregate either intra- or extracellularly. Triggered by factors such as MUTATION, POST-TRANSLATIONAL MODIFICATIONS, and environmental stress, it is generally associated with ALZHEIMER DISEASE; PARKINSON DISEASE; HUNTINGTON DISEASE; and TYPE 2 DIABETES MELLITUS.
Membrane glycosylphosphatidylinositol-anchored glycoproteins that may aggregate into rod-like structures. The prion protein (PRNP) gene is characterized by five TANDEM REPEAT SEQUENCES that encode a highly unstable protein region of five octapeptide repeats. Mutations in the repeat region and elsewhere in this gene are associated with CREUTZFELDT-JAKOB DISEASE; FATAL FAMILIAL INSOMNIA; GERSTMANN-STRAUSSLER DISEASE; Huntington disease-like 1, and KURU.
A phenyl-piperidinyl-butyrophenone that is used primarily to treat SCHIZOPHRENIA and other PSYCHOSES. It is also used in schizoaffective disorder, DELUSIONAL DISORDERS, ballism, and TOURETTE SYNDROME (a drug of choice) and occasionally as adjunctive therapy in MENTAL RETARDATION and the chorea of HUNTINGTON DISEASE. It is a potent antiemetic and is used in the treatment of intractable HICCUPS. (From AMA Drug Evaluations Annual, 1994, p279)
A familial disorder inherited as an autosomal dominant trait and characterized by the onset of progressive CHOREA and DEMENTIA in the fourth or fifth decade of life. Common initial manifestations include paranoia; poor impulse control; DEPRESSION; HALLUCINATIONS; and DELUSIONS. Eventually intellectual impairment; loss of fine motor control; ATHETOSIS; and diffuse chorea involving axial and limb musculature develops, leading to a vegetative state within 10-15 years of disease onset. The juvenile variant has a more fulminant course including SEIZURES; ATAXIA; dementia; and chorea. (From Adams et al., Principles of Neurology, 6th ed, pp1060-4)
A protein that is highly expressed in the nervous system as well as other tissues; its size and structure vary due to polymorphisms. Expanded CAG TRINUCLEOTIDE REPEATS have been identified in the Huntingtin (HD) Gene of patients with HUNTINGTON DISEASE and are associated with abnormal PROTEIN AGGREGATES. Huntingtin interacts with proteins involved in a variety of gene expression and cellular processes; it is also essential for embryonic development.
