NCT01767311
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.
NCT03507257
The Longitudinal Early-onset Alzheimer's Disease Study (LEADS) is a non-randomized, natural history, non-treatment study designed to look at disease progression in individuals with early onset cognitive impairment. Clinical, cognitive, imaging, biomarker, and genetic characteristics will be assessed across three cohorts: (1) early onset Alzheimer's Disease (EOAD) participants, (2) early onset non-Alzheimer's Disease (EOnonAD) participants, and (3) cognitively normal (CN) control participants.
NCT01760005
The purpose of this study is to assess the safety, tolerability, biomarker, cognitive and clinical efficacy of investigational products in participants with an Alzheimer's disease-causing mutation by determining if treatment with the study drug slows the rate of progression of cognitive/clinical impairment or improves disease-related biomarkers.
NCT06597942
The goal of this clinical trial is to learn if using deep repetitive transcranial magnetic stimulation (rTMS) targeting the precuneus is feasible, tolerable, and potentially efficacious for memory in Probable Alzheimer's Dementia. Previous work studying rTMS in Alzheimer's is mixed, but recent work studying rTMS of the precuneus is encouraging for both its short-term and long-term effects. The main questions this study aims to answer are: * Is deep rTMS of the precuneus feasible and tolerable in Alzheimer's? * Are there signs of positive brain changes in response to deep rTMS? * Is deep rTMS potentially efficacious for memory in Alzheimer's? Researchers will compare active stimulation to placebo stimulation while obtaining memory testing and measurements of the brain (imaging, scalp electrode measurements, bloodwork) to see if active treatment works to treat mild-to-moderate probable Alzheimer's Dementia. Participants will: * Engage with memory testing, brain scans, and bloodwork during a comprehensive assessment * Visit the clinic 3 times for 12 consolidated rTMS sessions, followed by 4 once weekly maintenance sessions * Be offered a full open-label active treatment course after completing their treatment course if they are initially in the placebo group
NCT05641688
This study is an open-label, multi-center, non-randomized pivotal Phase 3 study to assess the efficacy and safety of PET imaging with \[18F\]PI-2620 for detection of tau deposition in subjects with Alzheimer's disease (AD) and controls during lifetime when compared to histopathology obtained after death and completion of brain autopsy.
NCT06210035
In the current study, we will examine how two types of concentration meditation practices affect plasma biomarkers of Alzheimer's Disease (AD). We will also examine the effects of the two types of meditation practices on emotional well-being and episodic memory. Healthy adults aged 18-35 who meet all eligibility criteria will be invited to this study. Participants will be asked to engage in one week of daily meditation practice or no-intervention control task at home. They will also be asked to visit the lab twice, once before and once after the intervention, to provide blood samples to assess plasma biomarkers of AD and to complete emotion questionnaires and a memory test.
NCT03919162
This is a Phase 2A multi-center, randomized, double blind, placebo-controlled, parallel group study of varoglutamstat, with a stage gate to Phase 2B. In Phase 2A there will be adaptive dosing evaluation of three dose levels with exposure to varoglutamstat or placebo for a minimum of 24 weeks, with preliminary evaluation of both cognitive function and pharmacodynamic changes on EEG spectral analysis in approximately 180 participants. In the event that the stage gate for Phase 2B is reached, then Phase 2B will assesses efficacy and longer-term safety in a larger study group, i.e., 414.
NCT06874621
This study is to be conducted in participants with early Alzheimer's Disease to test VY7523, a new drug being researched for treatment of Alzheimer's Disease. This study will look at how safe the drug is and how it works in the brain. It was first tested in normal, healthy participants who volunteered to participate. The study will look at three different dose levels, starting with the lowest dose first and moving to higher doses and more participants after safety has been reviewed by doctors and researchers. Some patients will receive drug while others will receive placebo. This will help to better compare how the drug works between participants receiving drug and placebo. The study will last up to 6 months for the lower dose groups and 12 months for the highest dose group.

This study is a pre-screening process used to assess participants' potential eligibility for Roche interventional Alzheimer's disease studies.
NCT06808984
This is a study to evaluate the efficacy, safety, and tolerability of BMS-986368, a FAAH/MAGL inhibitor, for the treatment of agitation in participants with Alzheimer's Disease.
NCT06538116
The main purpose of this study is to look at how safe the study drug (mevidalen) is and whether it works to alleviate symptoms when given to people with mild to moderate Alzheimer Disease (AD) dementia. This is done by looking at participants: thinking and memory (cognition), everyday activities and sleep, AD symptoms, physical activity, irritability or anxiety. The study is expected to last approximately 26 weeks and may include up to 14 visits.
NCT06335173
The primary purpose of this study is to evaluate the efficacy of sabirnetug infusions administered once every four weeks (Q4W) in slowing cognitive and functional decline as compared to placebo in participants with early Alzheimer's disease.
NCT05557409

NCT04838301
A phase 2, double-blind, randomized, placebo-controlled clinical trial to evaluate the safety and efficacy of Allopregnanolone as a regenerative therapeutic for Alzheimer's disease.
NCT05291234
Alzheimer's disease (AD) is a progressive, irreversible neurological disorder and is the most common cause of dementia in the elderly population. Clinical symptoms of the disease may begin with occasional forgetfulness such as misplacement of items, forgetting important dates or events, and may progress to noticeable memory loss, increased confusion and agitation, and eventually, loss of independence and non-responsiveness. This study will assess how safe and effective ABBV-916 is in treating early AD. Adverse events, change in disease activity, and how ABBV-916 moves through body of participants will be assessed. ABBV-916 is an investigational drug being developed for the treatment of early AD. This study is conducted in 2 stages. Stage A is a multiple ascending dose study. There is a 1 in 4 chance that participants are assigned to receive placebo. Stage B is a proof-of-concept study. In Stage B, there is a 1 in 5 chance that participants will be assigned to receive placebo. The first 6 months of this study are "double-blind," which means that neither the trial participant nor the study doctors know which treatments will be given. This will be followed by a 2-year extension period in which all participants will receive ABBV-916. Approximately 195 participants aged 50-90 years will be enrolled in about 90 sites across the world. Participants will receive intravenous (IV) doses of ABBV-916 or placebo once every 4 weeks (Q4W) for 24 weeks and will be followed for an additional 16 weeks. Participants will have the option of participating in a 2-year, open-label, Extension Period receiving IV ABBV-916. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, magnetic resonance imaging (MRI), blood tests, checking for side effects and completing questionnaires.
NCT06544616
The purpose of this study is to assess the effect of JNJ-64042056 on cognitive decline, as measured by Preclinical Alzheimer's disease Cognitive Composite 5 (PACC-5) compared with placebo.
NCT03860857
The purpose of this research study is to understand the factors that underlie changes in thinking and memory with increasing age. The investigators will test the usefulness of MRI, PET, and cognitive testing in detecting subtle changes in the brain that precede cognitive decline. An addendum to this study includes additional PET scans to examine the relationship between tau protein in the brain and cognitive decline. Tau is a protein that is known to form tangles in the areas of the brain important for memory, and these tau tangles are a hallmark of Alzheimer's disease. This sub-study research aims to look at the tau accumulation in the brain using an investigational drug called MK-6240, which is a radio tracer that gets injected prior to a positron emission tomography (PET) scan.
NCT06647498
The purpose of this research study is to test the study drug, referred to as remternetug, to determine its effectiveness for the study treatment of asymptomatic (at risk) Alzheimer disease in individuals with AD-causing mutations. This study will also investigate the effects of remternetug on biomarkers (measures of the disease including brain scans, blood and spinal fluid tests), examine safety data to identify any potential benefits or risks, and examine how well participants can tolerate remternetug. Stage 1 will determine if treatment with the study drug prevents or reverses amyloid beta (Aβ) accumulation compared with placebo in participants with dominantly inherited Alzheimer's disease (DIAD). Stage 2 will evaluate the effect of early anti-amyloid treatment on downstream biomarkers of AD in treated participants compared to external control groups.
NCT06079190
The aim of this study is to assess the efficacy and safety of GSK4527226 in participants with early Alzheimer's Disease (AD) (including mild cognitive impairment \[MCI\] and mild dementia due to AD) of 2 dose levels of GSK4527226 compared to placebo.
