Active clinical trials for "Alzheimer Disease"

The purpose of this study is to determine the safety, tolerability and effect of JNJ-54861911 on level of amyloid-beta in Cerebrospinal Fluid (CSF) and plasma following 4 weeks of treatment in Japanese participants asymptomatic at risk for Alzheimer Dementia (ARAD) at the intended target dose range.

The purpose of this study is to determine the safety and effectiveness of 2,000 international units of Vitamin E (alpha tocopherol)on cognitive function of aging persons with Down syndrome. It is a randomized, double-blind, placebo-controlled trial lasting 36 months. It is expected that Vitamin E will slow the deterioration in cognitive functions associated with Alzheimer disease.

This is an efficacy and safety study evaluating a new treatment for subjects with mild to moderate Alzheimer's disease.

AZD0530 is an inhibitor of Src and Abl family kinases1. It has been developed as treatment for malignancies because these kinases play a role in tumor invasion and proliferation. However, the Src family kinases (SFKs) are highly expressed in brain and have major effects on synaptic plasticity2. Moreover, the investigators have recently shown that a specific SFK, namely Fyn, is aberrantly activated by specific conformations of the Amyloid Beta (Aß) peptide from Alzheimer's disease (AD). Genetic deletion of Fyn rescues AD deficits in preclinical models. This clinical trial will test the potential benefit of AZD0530 for Alzheimer's disease modification.

Clinically, many patients with AD show no response or minimal response to antipsychotics for symptoms of agitation/aggression or psychosis, or they have intolerable side effects on these medications. Antipsychotics have a wide range of side effects, including the risk of increased mortality (60-70% higher rate of death on antipsychotic compared to placebo) that led to an FDA black box warning for patients with dementia; a more recent review and meta-analysis showed a 54% increased risk of mortality. In addition, some patients show only partial response to antipsychotics and symptoms persist. For these reasons, the investigators need to study alternative treatment strategies. Currently, there is no FDA-approved medication for the treatment of psychosis or agitation in AD. The investigators innovative project will examine the efficacy and side effects of low dose lithium treatment of agitation/aggression with or without psychosis in 80 patients with AD in a randomized, doubleblind, placebo-controlled, 12-week trial (essentially a Phase II trial). The results will determine the potential for a large-scale clinical trial (Phase III) to establish the utility of lithium in these patients.

The purpose of this study is to evaluate the long-term safety and tolerability of JNJ-54861911 during 6 months of treatment in participants with early (predementia) alzheimer's disease (AD [degenerative disease of the brain characterized by the insidious onset of dementia, impairment of memory, judgment, attention span, and problem solving skills are followed by severe apraxias and a global loss of cognitive abilities]).

Purpose : to Evaluation of the Efficacy of Escitalopram for the Treatment of Depression in Alzheimer's Disease Trial Design : A 12-week, randomized, double-blind, parallel-group, placebo-controlled trial with an open-label, 12-week extension

Alzheimer's disease (AD), the most common dementing disorder of later life, is a major cause of disability and death in the elderly. Although a number of theoretical causes exist, the etiology of AD is still unknown. Consequently, the focus of treatments has been palliative, designed to ameliorate AD symptoms. Recent efforts, however, have revealed some surprising data suggesting that cholinesterase inhibitors (AchEIs), used over the last decade, and recently released memantine (an N-methyl-D-aspartate (NMDA) receptor antagonist), may confer protection to neurons. Thus, they may offer a slowing of cognitive decline and/or improvement in behavioral symptoms associated with memory impairment. Over the last decade, it has been well documented that mild cognitive impairment (MCI) increases the risk of conversion to AD and that coincident depression and MCI (Dep-MCI) further increases the risk 2 to 3 fold. The primary focus of this line of investigation is to treat the very high risk to dement patient population with Dep-MCI, before they develop AD, in the hopes of delaying AD onset. Memantine had not been studied in DEP-MCI patients. Since treatment of these patients with combined antidepressant and AChEIs has been associated with cognitive improvement in pilot studies, we explore whether treatment of DEP-MCI with memantine in addition to antidepressant treatment would benefit cognitive performance and lead to a low rate of conversion to dementia. We evaluate the cognitive and antidepressant benefit of combined open-label es-citalopram and memantine treatment over 48 weeks in a DEP-CI sample.

Alzheimer's disease is a devastating neurodegenerative disorder, for which there is currently no effective treatment to slow or halt progression. Beta amyloid peptide accumulates in the brains of those with Alzheimer's, and is thought to play a major role in triggering the dementia. The investigators recently characterized a molecular pathway by which ß-amyloid damages neurons, and showed that the protein termed Fyn kinase is crucial. Our data suggest that blocking Fyn will have a significant therapeutic benefit for Alzheimer's. Astra Zeneca has developed a blocker of Fyn and related kinases (AZD0530) for the treatment of cancer. Chronic AZD0530 administration is well tolerated in humans, and the investigators propose to test its potential as a novel Alzheimer's disease modifying therapy. This study will assess the safety and tolerability of AZD0530 in patients with Alzheimer's disease.
