Filter by:This study is being conducted to determine the safety, tolerability, and pharmacokinetics (PK) of three different doses of an investigational medication, EVP-6124, in individuals with mild to moderate Alzheimer's disease who are also taking an Alzheimer's medication (AChEI [acetylcholinesterase inhibitor]: either donepezil or rivastigmine). In addition, PK of AChEI medications will be assessed. Cognitive function will be evaluated on an exploratory basis.
Alzheimer's disease (AD) is a fatal degenerative disease of the brain for which there is no cure. AD causes brain cells to die. AD is thought to be caused by an excess of beta amyloid (β-amyloid), a sticky protein in the brain that forms amyloid plaques. At autopsy, AD patients are required to have these amyloid plaques in the brain in order to have a definitive diagnosis of AD. Inhibiting the enzyme gamma-secretase (γ-secretase) lowers the production of β-amyloid. Semagacestat (LY450139) is a functional γ-secretase inhibitor and was shown to lower β-amyloid in blood and spinal fluid in humans tested thus far and in blood, spinal fluid and brain in animals tested thus far. This study used several different tests to measure the effect of semagacestat on both β-amyloid and amyloid plaques for some patients. The buildup of amyloid plaques was measured by a brain scan that takes a picture of amyloid plaques in the brain. Other tests measured the overall function of the brain and brain size in some patients. In this trial, patients who initially received placebo (inactive sugar pill) were, at a certain point in the study, switched over to active drug, semagacestat. In other words, all patients could eventually receive active drug. Each patient's participation could last approximately 2 years. Patients taking approved AD medications were permitted to participate in this study and continue taking these medications during the study. All patients who completed this study had the option to continue receiving semagacestat by participating in an open label study. Preliminary results from this study (LFBC) (and another similar study LFAN [NCT00594568]) showed semagacestat did not slow disease progression and was associated with worsening of clinical measures of cognition and the ability to perform activities of daily living. Study drug was stopped in all studies. LFBC, LFAN and open label LFBF (NCT01035138) have been amended to continue collecting safety data, including cognitive scores, for at least seven months. The CT-Registry will reflect results of analyses from the original protocol in addition to those from the amended protocol.
The LifeZig Project is a research study of a new reminiscence activity for individuals with Alzheimer's Disease (AD) and other types of dementia, based on the LifeZig system, with personalized video channels containing old photographs and music on television. The goal of the LifeZig study is to enhance the quality of life for dementia patients and their families/caregivers, decrease the burden of care, and contribute to positive interaction between dementia patients and families/caregivers.
The aim of the study is to determine if regional cerebral blood flow, measured by dynamic arterial spin labeling (dASL), can be a biomarker for stage of Alzheimer's disease. The study is designed to be conducted in 2 parts in participants with mild to moderate Alzheimer's disease, and participants with normal cognition. Various imaging studies will be done using magnetic resonance imaging (MRI) and positron emission tomography (PET) along with neurocognitive assessments. Participants who meet the study-entry criteria will have up to 8 study visits. Repeat imaging studies may be required if the initial data are incomplete or un-interpretable. The maximum number of PET scans during the study will be limited to four.
The purpose of this study is to evaluate the hypothesis that in middle-aged, asymptomatic, adult children of persons with Alzheimer's disease (AD), atorvastatin therapy will beneficially affect mechanisms thought to contribute to AD risk by improving blood flow in the brain, improving cerebral perfusion, increasing brain activity patterns, and improving blood vessel function.
The aim of the study is the analysis of two inhibitors of Ach-E: galantamine and donépézil in over 65 years' old patients suffering from Alzheimer disease (MMSE between 20 and 26) without Alzheimer's medication.
The purpose of this study is to investigate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of multiple dosing Solanezumab in subjects with mild-to-moderate AD in Japanese population.
1. Assess the efficacy of varenicline, relative to placebo, on a performance based measure of cognition in patients with mild to moderate Alzheimer's disease 2. Evaluate the effects of varenicline on clinically relevant measures including attention and executive function, behavior, and clinician rated global change. 3. Evaluate the safety and tolerability of varenicline, relative to placebo, in patients with mild to moderate Alzheimer's disease 4. Evaluate the pharmacokinetics of varenicline in patients with mild to moderate Alzheimer's disease.
The purpose of this study is to evaluate the efficacy and safety of plasma exchange with 5% albumin in beta-amyloid peptide clearance in cerebrospinal fluid, and its effects in patients with mild-moderate Alzheimer's disease.
This is a Phase I, multicenter, randomized, double-blind, placebo-controlled study that will be conducted in the United States and consists of a single ascending-dose stage followed by a multidose, parallel-treatment stage. This study will be conducted in approximately 50 adult patients between 50-85 years old who have mild to moderate Alzheimer's disease.
