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.

NCT04464564
This study was conducted to evaluate the efficacy, safety, and tolerability of AVP-786 (deudextromethorphan hydrobromide \[d6-DM\]/quinidine sulfate \[Q\]) compared to placebo for the treatment of agitation in participants with dementia of the Alzheimer's type.
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.
NCT02446132

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.
