Filter by:This is a 12-month, multicentre randomised double-blind placebo-controlled Phase IIb study in patients with mild Alzheimer's dementia (AD). Patients will be randomised on a 1:1 ratio to receive liraglutide or matching placebo.
The investigators are conducting a study to try to improve our ability to identify older adults who are at high-risk for progression to Alzheimer's disease, several years before they have symptoms that might reduce their quality of life. The investigators believe they can increase the sensitivity of tests of memory and problem solving, by using a very small dose of a medication (scopolamine) that reduces the activity of the principal chemical system in the brain that is changing in the earliest stages of Alzheimer's disease. By pairing this "micro-dose" drug challenge (that is administered with a tiny needle placed just under the surface of the skin on the forearm), with our tests of memory and thinking, it is believed that the investigators can create a "stress test" that is very similar in concept to the use of the exercise treadmill to make the results of a heart EKG more sensitive to detect early disease, as a cardiac stress test for heart disease. The investigators want to create a similar stress test for Alzheimer's disease (AD).
The study tests the effect of the NeuroAD on Alzheimer patients' cognitive function. The NeuroAD uses non-invasive stimulation of both magnetic and cognitive training.
To investigate whether [18F]NAV4694 positron emission tomography (PET) scan findings have the ability to distinguish subjects with mild cognitive impairment (MCI) who progress to Alzheimer's disease (AD) from those who do not.
Physical exercise has proven to improve memory including in the elderly. Drugs developed to stop the underlying disease processes that cause Alzheimer's disease may succeed only with multimodal efforts to stimulate brain function. One purpose of the study is to test the clinical benefits of curcumin, a safe and effective compound isolated from the turmeric root (a component of Indian curry spices), which has been found to inhibit several potential disease pathways in Alzheimer's disease. Another purpose of this study is to determine how the addition of a physical exercise program in individuals with early memory problems may affect memory function or brain imaging and blood-based markers associated with Alzheimer's disease.
This is a multinational, multicenter, double-blind, placebo-controlled, parallel-group study using a Bayesian design with response adaptive randomization across placebo or 5 active arms of lecanemab to determine clinical efficacy and to explore the dose response of lecanemab using a composite clinical score (ADCOMS). BAN2401-G000-201 Core study is an 18-month study in which 3 dose levels (2.5, 5, and 10 mg/kg) are given biweekly (once every 2 weeks) to separate groups of participants and 2 dose levels (5 and 10 mg/kg) are given monthly (once every 4 weeks) to separate groups of participants. Participants will be from 2 clinical subgroups: mild cognitive impairment (MCI) due to Alzheimer's disease (AD) or mild Alzheimer's disease dementia. Frequent interim analyses will be conducted to continually update randomization allocation on the basis of the primary clinical endpoint. Any participant who completes the study treatment (Visit 42 [Week 79] of the Core study) or discontinues the Core Study will be eligible to participate in the Extension Phase, provided they meet the Extension Phase inclusion and exclusion criteria. Participants will receive 10 mg/kg biweekly for up to 60 months or until the drug is commercially available in the country, where the subject resides, or until the benefit-to-risk ratio from treatment with lecanemab is no longer considered favorable, whichever comes first. The Follow-up Visit in the Extension Phase will take place 3 months after the last dose of study drug.
Reliable diagnosis of Alzheimer's Disease (AD) at the predementia stage is currently considered to be a priority for research, as disease modifying therapies are being evaluated. Many studies focus on the functional and morphological assessment of the hippocampal formation. However, neurofibrillary tangles, associated with cognitive deficits, initially affect the anterior subhippocampal cortex (transentorhinal, entorhinal and perirhinal cortex) before reaching the hippocampus. Studies from our group have tried to investigate if the assessment of subhippocampal regions using cognitive tools and neuroimaging techniques could contribute to the diagnosis of AD at a very early stage. In a previous project, the investigators included 40 patients with single domain amnestic MCI (Mild Cognitive Impairment), known to be at high risk for AD and demonstrated that aMCI patients with a profile of subhippocampal dysfunction (impaired performance on a visual recognition memory task) display other clinical as well as imaging profiles of patients with early AD using MRI and SPECT. Longitudinal follow-up data in these patients is currently under way. Preliminary data indicates that evaluating the subhippocampal region using visual recognition tasks is highly predictive of AD over 6 years. The aim of this project is to obtain additional diagnostic data using a PET amyloid tracer (Florbetapir F18 AV45 F18), an in-vivo marker of one of the neuropathological lesions that define AD, of in order to enhance diagnostic accuracy AD in these patients. This approach will validate the hypothesis as to whether the assessment of subhippocampal dysfunction can contribute to the early diagnosis of AD.
While the cause of AD is still unknown, evidence suggests it develops because of a complex series of events in the brain that occur over time. Two pathways possibly involved in development of AD are inflammation and oxidative stress. Scientists have linked chronic inflammatory events in the brain with the onset and progression of Alzheimer's Disease. Oxidative stress has also been implicated in the pathogenesis of a number of neurological disorders including Alzheimer's Disease. Etanercept (Enbrel®) is an approved drug for the treatment of several forms of arthritis when administered by injection. Some research suggests that etanercept, when administered by injection into the tissues close to the spinal column (perispinally), may modulate certain aspects of the immune system and provide some beneficial effect for people with Alzheimer's disease. Studies suggest that supplementation with specific nutrients may also have a positive effect in support of cognitive function. This study will be conducted at one research office with volunteers who have been diagnosed with mild to moderate Alzheimer's disease. Each qualifying participant will be randomly assigned to receive an etanercept injection plus nutritional supplements for 6 weeks followed by a crossover and a washout period of 4 weeks to then receiving nutritional supplements alone or vice versa for another 6 weeks. Participants will undergo blood and urine safety assessments at the beginning and end of each 6 week treatment period. During 4 of the 6 weekly visits in the treatment period with the injections, you will complete the cognitive tests twice; once before and once 2 hours after the injection. During 4 of the 6 weekly visits in the treatment period without the injections, you will also complete the cognitive tests twice; once before and once 2 hours after being asked to lie down onto a table for 5 minutes. You will be allowed to continue your standard of care for Alzheimer's disease throughout your participation in the study.
The purpose of this study is to compare exposure to general anesthesia between cases with a diagnosis of Alzheimer´s disease and controls without diagnosis, through studies of medical records. The investigators wish to explore if there is a relationship between exposure to general anesthesia and the development of Alzheimer´s disease.
This is a phase 2, open-label, multiple-center, non-randomized single dose study to assess the safety and efficacy of [18F]NAV4694 PET imaging in detecting beta-amyloid plaque in the brain in subjects with probable AD compared with healthy volunteers.
