Active clinical trials for "Alzheimer Disease"

To investigate the potential to reduce concomitant antipsychotic medication use in subjects with moderate dementia of Alzheimer's type, treated with memantine.

The purpose of this study is to evaluate the long-term safety and tolerability of dimebon in subjects with moderate-to-severe Alzheimer's Disease.

To document effectiveness, safety, and tolerability of donepezil in patients with mixed AD/VaD, and to further document the effectiveness, safety, and tolerability of donepezil in patients with VaD. The effects of donepezil on executive functioning, behavior, general cognition, ADLs and global functioning will be assessed.

No Dimebon clinical data exist yet in patients with disease that has advanced to the moderate-to-severe stage. Therefore, this study evaluates the safety and efficacy of Dimebon in patients with moderate-to-severe AD who are receiving existing background therapy with memantine.

Oxidative damage by free radicals may be involved in causing Alzheimer's disease (AD). Free radicals may lead to death of nerve cells and decline in brain function. Certain antioxidants may suppress this free radical damage associated with AD. Carotenoids are a family of naturally occurring antioxidants that have important functions for human health. Carotenoids are known to reduce oxidative damage, but their effects have not been studied in AD patients. The objective of the study is to examine whether lutein supplementation helps to reduce oxidative damage from free radicals in AD patients.

This is a study to evaluate the safety, tolerability and blood levels of PF-03654746 in subjects will mild to moderate Alzheimer's disease.

Curcumin is shown to impact several different pathways of neuroprotection, however clinical trials have not shown positive results, due to the poor bioavailability of curcumin. This study is designed to determine efficacy and safety of high-bioavailability curcumin formulation (Longvida) in subjects with Alzheimer's disease.

Primary: To assess the safety and tolerability of ascending multiple oral doses of SAM-315, an investigational drug, in healthy young adult and elderly subjects. Secondary: To assess the Pharmacokinetic and Pharmacodynamic profiles of multiple oral doses of SAM-315 in healthy young adult and elderly subjects.

The purpose of this protocol is to measure a receptor in the brain using positron emission tomography (PET) that is involved in inflammation.

The purpose of this study is to evaluate the safety and efficacy of five fixed dosage levels of FK962 or placebo for 24 weeks in subjects with mild to moderate Alzheimer's disease. Patient visits are every six weeks with limited efficacy measurements at week 6 and 18.
