Active clinical trials for "Alzheimer Disease"

The purpose of this study was to assess the safety, tolerability, and pharmacokinetic (PK) of TAK-071 when administered as single rising dose (SRD) and multiple rising dose (MRD) orally in healthy participants and participants with mild cognitive impairment (MCI) or mild Alzheimer disease (AD).

Study to assess symptomatic efficacy, safety and tolerability of talsaclidine in patients with mild to moderate dementia of Alzheimer type

The purpose of this study is to evaluate the long-term safety, tolerability and antibody response of Lu AF20513 in patients with Alzheimer's disease who have completed the 16026A study.

This is an open-label, multicenter, rollover study to evaluate the safety and tolerability of long-term administration of gantenerumab in participants with AD. All participants who have completed the open-label extensions (OLEs) of Studies WN25203 or WN28745 will be eligible to participate in Part 1 of this study. Of these, participants who complete Week 104 visit in Part 1 will be eligible for Part 2 of this study. Participants will continue receiving open-label gantenerumab by subcutaneous (SC) injection every four weeks (Q4W) at the same dose as administered in the parent studies (part 1)/ Week 104 visit (part 2).

Dementia is a clinical syndrome that is the result of distinct underlying pathologies including Alzheimer's disease (AD). Despite more than two decades of research on prevention and treatment of dementia and aging-related cognitive decline, highly effective preventive and therapeutic strategies remain elusive. Many features of dementia render it especially challenging. Indeed development of disease occurs insidiously over the course of years or decade. In addition, the causes of dementia and determinants of its severity are likely multi-factorial. To overcome these challenges and better understand the causes and course of AD and related disorders, long term follow-up studies of persons at high risk of dementia are required including multidimensional and harmonized assessment of risk factors, phenotypes (cognition, neuropsychiatric symptoms, physical health, self rated health) and endophenotypes (blood markers, genetic markers, neuroimaging markers). This project proposes an extension of the follow-up of Memento participants over 5 to 10 years with of focus on cognitive outcomes and comorbidities.

Cognitive frailty, characterized by the coexistence of physical frailty and cognitive impairment, is a robust indicator of cognitive decline. Recognizing its significance, the International Association of Gerontology and Geriatrics and the International Academy on Nutrition and Aging have advocated for the use of cognitive frailty assessment as a means of monitoring the progression of mild cognitive impairment towards debilitating conditions like dementia, Alzheimer's disease, and loss of independence. Despite the clear need, a practical and remotely accessible tool for measuring cognitive frailty is currently lacking, especially within the context of telehealth visits. With telehealth video-conferencing becoming increasingly popular, accepted by healthcare payers, and preferred by older adults who may face difficulties traveling to a clinic, there is a pressing need for a software-based solution for remote cognitive frailty assessment that can be easily integrated into existing telehealth systems. This study proposes designing and validating a video-based solution to remotely monitor cognitive-frailty in older adults.

In the United States and around the world, people are living longer lives. As the population ages, so does the number of older adults who may experience declines in memory, attention, reasoning, or other thinking skills. Some of these changes in cognition can be treated and reversed if caught early. Others can be slowed down and hopefully one day prevented. Unfortunately, people with cognitive decline or very mild dementia often are not recognized until late in the disease course when treatments are less effective. As the first health care professional most people reach out to about medical concerns, primary care providers play a critical role in detecting cognitive decline early. While many primary care providers conduct cognitive screening at Medicare Annual Wellness Visits and when patients voice concerns, 9 out of 10 would like more information about who to screen, which assessment tool to use, and what to say if screening is positive. Deciding who to screen with a brief cognitive assessment tool is a key part of the process because not everyone needs to be screened, and primary care providers already face time pressures to address the obvious and immediate concerns of their patients. The long-term goal of this project is to develop a risk assessment and cognitive screening tool that requires minimal time and effort from primary care providers or their staff and is sensitive to cognitive decline in older adults from diverse educational and racial/ethnic backgrounds. The tool will be integrated into electronic health record systems to make it easy for primary care providers and patients to see results. The specific aims of the first phase of the project are to modify an existing dementia risk screening index to identify older adults who are at high-risk for cognitive impairment, develop a brief cognitive assessment tool using tasks that are easy for older adults to perform yet are sensitive to cognitive decline, confirm their utility in 150 people with varying levels of cognitive abilities that have already been well defined, and test ways to integrate findings into the electronic health record. The specific aims for the second phase are to further test the effectiveness of the newly developed tool in 250 older adults receiving care in a primary care clinic, to find out from primary care providers using the tool how much they liked it and if it was useful and easy to use, and to integrate findings into multiple electronic health record systems. Findings from this project will fill a gap in the existing toolkit of primary care providers and will make screening for cognitive decline quick, easy, and effective.

This is a randomized, cross over study to determine the efficacy of coconut oil in subjects with mild to moderate Alzheimer's disease.

The primary objective of this study is to evaluate the safety and tolerability of multiple doses of Aducanumab (recombinant, fully human anti-Aβ IgG1 mAb) in participants with prodromal or mild Alzheimer's Disease (AD). The secondary objectives of this study are to assess the effect on cerebral amyloid plaque content as measured by florbetapir-fluorine-18 (18F-AV-45F-AV-45) positron emission tomography (PET) imaging, to assess the multiple dose serum concentrations of Aducanumab and to evaluate the immunogenicity of Aducanumab after multiple dose administration in this population.

The purpose of this multicenter trial is to assess the efficacy and safety of MK-7622 compared with placebo as adjunctive therapy to acetylcholinesterase inhibitors (AChEIs) for the symptomatic treatment of participants with mild to moderate Alzheimer's Disease (AD). The trial consists of two stages: Stage 1 and Stage 2. In Stage 1, participants will be randomized to receive either placebo or MK-7622 45 mg once daily. In Stage 2, participants will be randomized to receive either placebo or MK-7622 (dose: 5, 15 or 45 mg once daily). Participants will be enrolled in only one stage; the duration of each stage is approximately 26 weeks. Interim analyses will be performed in both Stage 1 and Stage 2 to determine whether the trial should continue. The primary study hypotheses are the following: Stage 1 - MK-7622 45 mg once daily is superior to placebo with respect to improving cognition in participants with mild to moderate AD as assessed by mean change from baseline in the 11-item Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog11) at Week 12; Stage 2 - At least one of the top two doses of MK-7622 (15 mg once daily, 45 mg once daily) is superior to placebo with respect to improving cognition in participants with mild to moderate AD as assessed by mean change from baseline in ADAS-Cog11 at Week 12.
