Filter by:The objective of this 3-month study is to assess the safety and efficacy of EHT 0202 in addition to acetylcholinesterase inhibitor in patients suffering from Alzheimer's Disease.
The objective of the study is to define the performance of blood-based signatures for Alzheimer's Disease (AD) in different patients populations including AD, non-AD dementia, and non-demented controls.
The purpose of this study is to evaluate the potential benefits of CERE-110 in the treatment of Alzheimer's disease. CERE-110 is an experimental drug that is designed to help nerve cells in the brain function better. CERE-110 uses a virus to transfer a gene that makes Nerve Growth Factor (NGF), a protein that may make nerve cells in the brain healthier and protect them from dying. The virus used in CERE-110 does not cause disease in people. CERE-110 has been carefully studied in laboratory animals and is in the early stages of being tested in people. Fifty patients with mild to moderate Alzheimer's disease will participate in this study. Half of the study subjects will have CERE-110 injected into the brain during a surgical procedure, while the other half will undergo a "placebo" surgery where no medication will be injected. All study participants will be followed for at least two years after surgery.
The objectives of this study are to assess the safety, tolerability and pharmacokinetics of ABT-126 in elderly subjects.
Pre-clinical studies have demonstrated that memantine can decrease the neuronal toxicity associated with excessive glutamate release and calcium overload in neurons. Previous studies have shown that memantine helps to treat the symptoms of Alzheimer's Disease (AD). In AD, the rate of brain tissue loss, or atrophy, is faster than in normal aging and this seems to go hand in hand with some of the symptoms of the disease. This suggests that memantine treatment in AD could provide both symptomatic improvement and neuro-protective effects. The purpose of this study was to show whether memantine, in addition to providing symptomatic benefits, can slow the rate of brain atrophy as assessed using magnetic resonance imaging (MRI) technology.
The primary objective of this protocol is to determine if brain amyloid imaged with florbetapir F 18 (18F-AV-45) PET scans is predictive of progressive cognitive impairment during the subsequent 36 months for groups of: normal controls, mild cognitive impairment and Alzheimer's disease. Hypothesis 1: The probability a subject will experience progressive cognitive impairment within 36 months of imaging will be greater in subjects whose 18F-AV-45 PET scan was rated amyloid positive compared to subjects whose PET scan was rated amyloid negative. The secondary objective is to determine the stability, over 36 months of a clinical diagnosis, of AD in patients with an amyloid positive 18F-AV-45 PET. Hypothesis 2: The diagnosis of AD will remain unchanged in patients whose PET scan were rated as amyloid positive.
The study is designed to test the relationship between measurements of brain amyloid using florbetapir F 18 PET imaging and true levels of amyloid by dissection of the brain at autopsy. Amyloid in the brain is a key feature of Alzheimer's Disease (AD).
This study will evaluate the performance characteristics of a novel [18F] amyloid detection ligand (18F]-AV-45) with respect to its ability to distinguish patients with clinically-diagnosed probable Alzheimer's disease from cognitively normal elderly subjects and to independently compare its diagnostic performance characteristics with the ability of [11C]PIB to correctly categorize the same subjects. SPECIFIC HYPOTHESES 1. Individuals with a clinical diagnosis of probable Alzheimer's disease will have increased brain retention of [18F]-AV-45 compared to cognitively normal elderly individuals. 2. There will be no clinically meaningful difference in the amyloid retention performance characteristics of [18F]-AV-45 and [l1C]PIB.
The purpose of this study is to determine whether this drug can help symptoms of aggression and agitation in participants with Alzheimer's disease.
This study will investigate the ability of ST101 to improve memory in people with Alzheimer's disease who currently receive 10 mg Aricept® (donepezil) per day. This study also will examine the safety and tolerability of the drug. This study is evaluating 3 different dose levels of ST101 and placebo. Patients will have a 1 in 4 chance of getting placebo. All eligible subjects will be provided with bottles of 10 mg Aricept (donepezil) during the study drug administration part of the study.
