Valproate in Dementia (VALID) Clinical Trials Info presented on Clinical Trials Search isn't intended to be a substitute for qualified medical advice, visits or professional assistance by using a real mD. We are not docs. Always confer with your physician about Valproate in Dementia (VALID) conditions. Clinical Trials Search.org is a website committed to listing clinical research studies in human subjects. Valproate in Dementia (VALID) Clinical research trials and Valproate in Dementia (VALID) health trials occur in many of cities throughout the US. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally evaluate the effectivity of new does drugs. The intent of the studies / undertakings is to resolve particular human health questions. Clinical trials are a popular way for physicians, government agencies, and private sector companies to detect remedies for all sorts of conditions, including Valproate in Dementia (VALID). Valproate in Dementia (VALID) Clinical Trials and other clinical trials permit volunteers to obtain healthcare treatment alternatives before they are available to the masses. Most times the participants undergo professional assistance for without cost, and occasionally they are compensated for their time. Occasionally there is a cost for a Valproate in Dementia (VALID) clinical trial. Test subjects typically receive the most expert healthcare available for their Valproate in Dementia (VALID) condition. Dangers are a reality, however, and may include more or frequent mD visits, healthcare dangers (perhaps life-endangering), and/or the treatment being ineffectual. Trials are federally regulated with rigid guidelines to protect clinical trials patients.

Valproate in Dementia (VALID)
For Condition: Alzheimer Disease
Status: Recruiting
Sponsor(s): National Institute on Aging (NIA) , Alzheimer's Disease Research Center, University of California, San Diego
Synopsis: The purpose of this trial is to demonstrate whether valproate therapy delays the emergence of agitation and/or psychosis in outpatients with probable Alzheimer’s disease (AD) who have not experienced agitation and psychosis in their illness. A secondary aim is to determine whether valproate therapy delays the progression of cognitive and functional measures of illness. This trial will also assess the tolerability and safety of low-dose, long-term valproate therapy. Valproate, an anticonvulsant drug, was selected because of its possible symptomatic efficacy for agitation in AD, known safety profile in numerous clinical populations, and in view of recent data supporting its neuroprotective potential in AD.
Details: This study represents a novel clinical trial strategy designed to assess both prospective "prophylactic" therapy for psychopathology in Alzheimer's disease (AD) and to assess an approach that may alter several aspects of the pathophysiology of AD, and perhaps resulting in alteration of clinical progression of illness. Intrepretation of these results will be supported by study of relevant biomarkers and imaging data. Valproate was selected because of its possible symptomatic efficacy for agitation in AD, known safety profile in numerous clinical populations, and in view of recent data supporting its neuroprotective potential in AD. The primary hypothesis is that chronic valproate administration to participants with AD who lack agitation and psychosis at baseline will delay the emergence of agitation and/or psychosis. An effect of this nature may have significant public health implications, for instance, by delaying institutionalization. This is a randomized, placebo-controlled, double blind, multicenter 26-month trial of valproate therapy at a target dose of 10-12 mg/kg/day in 300 outpatients with mild to moderate Alzheimer's Disease (AD) who lack agitation and psychosis at baseline and since onset of illness. Participants will have regular clinic visits as well as telephone contacts for assessment of behavior, cognition, function, safety and tolerability. The chief secondary aim is to determine whether valproate administration to participants with AD will attenuate clinical progression of illness measured by a reduced rate of cognitive or functional decline. In addition, issues related to safety and tolerability with low-dose (10-12 mg/kg/day) therapy will be addressed. Biological specimens will be obtained to study markers selected for their relevance to the disease as well as the postulated mechanism of action of the valproate therapy. MRI scans will be performed prior to experimental treatment and after one year in a subset of participants in order to address possible drug-placebo differences in brain volume measures. Approximately 300 participants from 25-35 clinical trial centers in the United States will be enrolled. Participation will include men and women with a diagnosis of probable Alzheimer’s disease, age 55 or older, weighing at least 40 kg (88.2 lbs.), residing in the community at baseline, MMSE 10-20 inclusive, who have not experienced agitation or psychosis since the onset of their illness and who do not require treatment with psychotropic medications with the exception of antidepressants used only for treatment of depressive symptoms and limited use of sedatives for sleep. Participants, their relatives, guardians or authorized representatives and informants will be given ample opportunity to inquire about details of the study. Informed consent forms covering consent for the trial itself as well as the genetic research and biological sample storage and MRI scans will be provided to protect the patient's rights and confidentiality.
