The reason for this study is to see how safe and effective the study drug donanemab is in participants with early Alzheimer's disease. Additional participants will be enrolled to an addendum safety cohort. The participants will be administered open-label donanemab. Trial participants who were dosed with donanemab in the main study will be enrolled to a 3-year follow up addendum. No study drug will be administered during this follow up.
NCT05704309
The DPPOS AD/ADRD project will address the overarching question: What are the determinants and the nature of cognitive impairment among persons with pre-diabetes (PreD) and type 2 diabetes (T2D), who are a high-risk group for cognitive impairment and represent a large fraction of the United States (US) population? This U19 proposal addresses the National Alzheimer's Project Act goal to "prevent, halt, or reverse AD" in the high-risk group of persons with pre-diabetes and type 2 diabetes, who represent over half of the population aged 60 years and older in the US.
NCT06416072
The APEX study is a multicenter, observational study designed to capture longitudinal follow-up of plasma biomarkers and cognitive and functional assessments on individuals who screen failed in the AHEAD study over approximately 4 years. Approximately 1000 participants will be enrolled across three groups: * Group A: Approximately 500 participants who are discordant on screening (plasma positive / Positron Emission Tomography (PET) negative), * Group B: Approximately 250 participants who are concordant on screening (plasma negative / PET negative), and * Group C: Approximately 250 participants selected from the individuals who previously screen failed prior to PET for the AHEAD study with oversampling of racial and ethnic populations underrepresented in Alzheimer's disease (AD) clinical trials. Primary Objectives: * Collect longitudinal cognitive and functional assessments and blood-based biomarker data * Evaluate, characterize, and compare the longitudinal cognitive and functional data between the three groups of participants * Compare longitudinal change across race and ethnicity, sex, and Apolipoprotein E (ApoE) status Exploratory Objectives: • Collect baseline amyloid PET on participants without prior amyloid PET data (Group C)
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.
NCT05310071
The primary objective of this study is to verify the clinical benefit of monthly doses of aducanumab in slowing cognitive and functional impairment as measured by changes in the Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) score as compared with placebo in participants with early Alzheimer's disease.
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.
NCT03887455
This study will be conducted to evaluate the efficacy of lecanemab in participants with early Alzheimer's disease (EAD) by determining the superiority of lecanemab compared with placebo on the change from baseline in the Clinical Dementia Rating-Sum of Boxes (CDR-SB) at 18 months of treatment in the Core Study. This study will also evaluate the long-term safety and tolerability of lecanemab in participants with EAD in the Extension Phase and whether the long-term effects of lecanemab as measured by the CDR-SB at the end of the Core Study is maintained over time in the Extension Phase. Extension Phase Part B will continue dosing with lecanemab in countries where lecanemab may not be commercially available.

NCT05669365
The Care Ecosystem is an accessible, remotely delivered team-based dementia care model, designed to add value for patients, providers and payers in complex organizational and reimbursement structures. Care is delivered via the phone and web by unlicensed Care Team Navigators, who are trained and supervised by a team of dementia specialists with nursing, social work, and pharmacy expertise. The evidence base to date suggests that the Care Ecosystem improves outcomes important to people with dementia, caregivers, and payers when delivered in a controlled research environment, including reduced emergency department visits, higher quality of life for patients, lower caregiver depression, and reduced potentially inappropriate medication use (Possin et al., 2019; Liu et al., 2022). The investigators propose a rapid pragmatic trial in 6 health systems currently offering the Care Ecosystem program in geographically and culturally diverse populations. The investigators will leverage technology, delivering care via the phone and web and using electronic health records to monitor quality improvements and evaluate outcomes while maximizing external validity. The investigators will evaluate the effectiveness of the Care Ecosystem on outcomes important to patients, caregivers, healthcare providers, and health systems during the pandemic. By evaluating the real-world effectiveness in diverse health systems that are already providing this model of care, this project will bridge the science-practice gap in dementia care during an unprecedented time of heightened strain on family caregivers, healthcare providers and health systems.
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).
