NCT05703490
Difficulties in performing instrumental activity of daily living (IADL) is often an indicator of cognitive decline in older adults, and monitoring IADL and daily functioning can assist in early diagnosis of dementia. The current methods for assessment of IADL are often restricted to a single domain assessment (e.g. managing medication), or rely on subjective reporting by the patient or caregivers. Patients with mild AD typically lack awareness of their IADL deficits and generally overestimate their functional capacity. Proxies are also not always a reliable source of information, as they have a tendency to over or underestimate IADL deficits. In some cases, a proxy is not available or does not have enough knowledge about the patient's functional capacity. Direct measures taken during performance of IADL-related tasks in the clinic have better validity and do not suffer from reporter bias. However, they allow observation of only a small set of tasks and, even then, are quite time-consuming. To date, there are no objective methods for continuous and remote monitoring and assessment of IADL. The National Institute on Aging (NIA) has identified this need and released a specific request for SBIR/STTR applications. In response, BioSensics, in collaboration with Baylor College of Medicine (BCM), proposes to develop and commercialize a robust system for objective and continuous remote monitoring of IADL. This innovative platform, called IADLSys, will detect the timing and type of IADL for a wide range of daily functions, and will also monitor the user's physical activity and life-space.
NCT06284213
Biomarkers for Vascular Contributions to Cognitive Impairment and Dementia (MarkVCID) is an NIH-funded consortium dedicated to finding biomarkers involved in age-related thinking and memory problems. Alzheimer's disease and other dementias leave signatures on brain scans or in the blood called biomarkers. The MarkVCID study will measure a panel of candidate biomarkers in 1800 participants and watch them closely to see what they tell us about changes in brain function and risk of memory loss. Age-related problems in thinking and memory represent some of the greatest risks to public health in the US and globally. Diseases that affect small blood vessels in the brain have been shown to be major contributors to these changes. However, research and patient care can be held back by limited biomarkers that identify who should be treated. The MarkVCID Consortium includes 17 US medical centers, a Coordinating Center, an External Advisory Committee, and NIH leadership. Data and biospecimens collected as part of this research study will be stored in a research database and biorepositories, so that researchers can use this information to study brain function.
NCT01231971
The purpose of this study is to build upon the information obtained in the original Alzheimer's Disease Neuroimaging Initiative (ADNI1) and ADNI-GO (Grand Opportunity; a study funded through an NIH grant under the American Recovery and Reinvestment Act), to examine how brain imaging technology can be used with other tests to measure the progression of mild cognitive impairment (MCI) and early Alzheimer's disease (AD). ADNI2 seeks to inform the neuroscience of AD. This information will aid in the early detection of AD, and in measuring the effectiveness of treatments in future clinical trials.
NCT03393520
This study will be conducted to evaluate the efficacy, safety, and tolerability of AVP-786 compared to placebo, for the treatment of agitation in participants with dementia of the Alzheimer's type.
NCT01767909
An urgent need exists to find effective treatments for Alzheimer's disease (AD) that can arrest or reverse the disease at its earliest stages. The emotional and financial burden of AD to patients, family members, and society is enormous, and is predicted to grow exponentially as the median population age increases. Current FDA-approved therapies are modestly effective at best. This study will examine a novel therapeutic approach using intranasal insulin (INI) that has shown promise in short-term clinical trials. If successful, information gained from the study has the potential to move INI forward rapidly as a therapy for AD. The study will also provide evidence for the mechanisms through which INI may produce benefits by examining key cerebral spinal fluid (CSF) biomarkers and hippocampal/entorhinal atrophy. These results will have considerable clinical and scientific significance, and provide therapeutically-relevant knowledge about insulin's effects on AD pathophysiology. Growing evidence has shown that insulin carries out multiple functions in the brain, and that insulin dysregulation may contribute to AD pathogenesis. This study will examine the effects of intranasally-administered insulin on cognition, entorhinal cortex and hippocampal atrophy, and cerebrospinal fluid (CSF) biomarkers in amnestic mild cognitive impairment (aMCI) or mild AD. It is hypothesized that after 12 months of treatment with INI compared to placebo, subjects will improve performance on a global measure of cognition, on a memory composite and on daily function. In addition to the examination of CSF biomarkers and hippocampal and entorhinal atrophy, the study aims to examine whether baseline AD biomarker profile, gender, or Apolipoprotein epsilon 4 (APOE-ε4) allele carriage predict treatment response. In this study, 240 people with aMCI or AD will be given either INI or placebo for 12 months, following an open-label period of 6 months where all participants will be given active drug. The study uses insulin as a therapeutic agent and intranasal administration focusing on nose to brain transport as a mode of delivery.
NCT05307692
The purpose of this study is to investigate the effect of seltorexant versus placebo on the sum of Agitation and Aggression domain scores (A plus A) of the Neuropsychiatric Inventory-Clinician rating (NPI-C) in participants with probable Alzheimer's Disease (AD) with clinically significant agitation/aggression.
NCT03786471
D-CARE: The Dementia Care Study This pragmatic randomized clinical trial of 2150 persons with dementia and their caregivers, at four diverse clinical trial sites in the United States, compares the effectiveness and cost-effectiveness of 18 months of health systems-based dementia care provided by a Dementia Care Specialist (nurse practitioner or physician assistant) who works within the heath system versus community-based dementia care provided by a Care Consultant (social worker, nurse, or therapist) who works at a Community-Based Organization (CBO). The trial will also compare the effectiveness and cost-effectiveness of both models versus usual care.
NCT05399888
In this study, researchers will learn more about a study drug called BIIB080. The study will focus on participants with mild cognitive impairment or mild dementia due to AD. The main question researchers are trying to answer is if BIIB080 can slow the worsening of AD more than placebo. It will focus on what dose of BIIB080 slows worsening of AD the most. To help answer this question, researchers will use the Clinical Dementia Rating-Sum of Boxes, also known as the CDR-SB. * Clinicians use the CDR-SB to measure several categories of dementia symptoms. * The results for each category are added together for a total score. Lower scores are better. Researchers will also learn more about the safety of BIIB080. The study will be split into 2 parts. The 1st part is the Placebo-Controlled Period. The 2nd part is the Long-Term Extension (LTE) Period. The 2nd part of the study will help researchers learn about the long-term safety of BIIB080, and how it affects the participant's daily life, thinking, and memory abilities in the longer term. A description of how the study will be done is given below. * After screening, participants will first receive either a low dose or high dose of BIIB080, or a placebo, as an injection into the fluid around the spinal cord (cerebrospinal fluid). A placebo looks like the study drug but contains no real medicine. * Participants will receive BIIB080 or placebo once every 12 weeks or 24 weeks. * After 76 weeks of treatment in the Placebo-Controlled Period, eligible participants will move onto the Extension Treatment period, which will last 96 weeks. * In the extension period, participants who received placebo will be switched to high dose BIIB080 every 12 or 24 weeks. * Participants may be in the study for up to 201 weeks, or about 4 years. This includes the screening and follow-up periods. * Participants can continue to take certain medications for AD. Participants must be on the same dose of medication for at least 8 weeks before the screening period. * After the screening period, most participants will visit the clinic every 6 weeks.

NCT06025877
There is a major unmet need for timely, non-invasive, and low-burden evaluation of patients presenting with mild cognitive impairment (MCI) and dementia. MCI impacts 12-18% of people in the United States over age 60 years (Alzheimer's Association. Mild Cognitive Impairment (MCI) available at https://www.alz.org/alzheimers-dementia/what-is-dementia/related\_conditions/mild-cognitive-impairment. Accessed August 16, 2022). MCI does not substantially interfere with daily activities, although complex functional tasks may be performed less efficiently (Knopman DS, Petersen RC. Mild cognitive impairment and mild dementia: a clinical perspective. Mayo Clin Proc. 2014;89(10):1452-1459. doi:10.1016/j.mayocp.2014.06.019). Approximately 30% of MCI patients have Alzheimer's disease (AD) as a cause of their symptoms (Lopez,OL, Kuller LH, Becker JT, et al. Incidence of dementia in mild cognitive impairment in the cardiovascular health study cognition study. Arch Neurol. 2007;64(3):416-420.doi:10.1001/archneur.64.3.416)). In contrast, dementia is defined by chronic, acquired loss of two or more cognitive abilities caused by brain disease or injury, often associated with significant interference with the ability to function at work or at usual activities. (Knopman DS, Petersen RC. Mild cognitive impairment and mild dementia: a clinical perspective. Mayo Clin Proc. 2014;89(10):1452-1459. doi:10.1016/j.mayocp.2014.06.019). Approximately 60-80% of dementia patients have AD as a cause of their symptoms (Alzheimer's Association. Mild Cognitive Impairment (MCI) available at https://www.alz.org/alzheimers-dementia/what-is-dementia/related\_conditions/mild-cognitive-impairment. Accessed August 16, 2022).
