Active clinical trials for "Alzheimer Disease"

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.

STUDY OBJECTIVES Primary: To assess the safety and tolerability of ischemia-tolerant allogeneic human mesenchymal stem cells (hMSCs) manufactured by Stemedica versus placebo administered intravenously to subjects with mild to moderate dementia due to Alzheimer's disease. Secondary: To assess the preliminary efficacy of hMSCs versus placebo in subjects with Alzheimer's-related dementia, as evidenced by neurologic, functional, and psychiatric endpoints.

Alzheimer's disease (AD) is the most prevalent neurodegenerative disease of aging. Neuropsychiatric symptoms (NPS) in AD are a major cause of burden to patients, caregivers, and society and are near-universal at some point in the AD course. One of the most troubling of these symptoms is agitation (Agit-AD), typified by a variety of problem behaviors including combativeness, yelling, pacing, lack of cooperation with care, insomnia, and restlessness. There is a great need for better interventions that target Agit-AD, a major source of patient disability as well as caregiver burden and stress, particularly in the case of moderate to severe agitation. This pilot trial could open the door to "re-purposing" Dronabinol (Marinol®) as a novel and safe treatment for Agit-AD with significant public health impact.

In this study, it is aimed to compare the effects of cognitive exercises applied on long-term internet environment to the cognitive level of patients who received donepezil, memantine or donepezil / memantin combination therapy.

It has been recently discovered that the FDA-approved drug, hydralazine, has anti-neurodegenerative efficacy based on three intriguing observations. hydralazine; 1) activates the Nrf2 pathway that controls more than 200 antioxidant proteins, 2) rejuvenates mitochondria and increases their respiration capacity and adenosine triphosphate production, 3) activates autophagy which has pathophysiological roles such as intracellular aggregate clearance. There is an emerging agreement that autophagy-lysosome defects occur early in the pathogenesis of Alzheimer's disease (AD). Nrf2 is another pathway known to be impaired in the hippocampus of AD patients who need antioxidant protection the most. Rejuvenation of mitochondria is crucial for fighting AD, as neuronal cells need more energy to afford activation of pathways such as autophagy and Nrf2. The prime objective of this application is to conduct a randomized clinical trial to assess the efficacy of hydralazine in early-stage AD patients who take one of the acetylcholinesterase inhibitor (AChEI) donepezil, rivastigmine, or galantamine.

This study will evaluate the safety, tolerability, and feasibility of 12 month oral rapamycin treatment in older adults with amnestic mild cognitive impairment (aMCI) and early stage Alzheimer's disease (AD).

The objective of the study is to determine the safety, feasibility, and efficacy of senolytics in older adults with amnestic mild cognitive impairment (MCI) or early-stage AD (Clinical Dementia Rating (CDR)=0.5 or 1) who are tau PET positive

This is a randomized, double-blinded, placebo-controlled, crossover trial that aims to 1) determine the efficacy of THC-free cannabidiol (CBD oil) in reducing the severity of agitation among participants and 2) determine whether THC-free CBD oil can reduce the burden on caregivers and increase the participants' quality of life.

This is a randomized, double-blind clinical trial of a daily oral dose of 200 mg emtricitabine vs. placebo in 35 participants with biomarker-confirmed MCI or mild to moderate dementia due to Alzheimer's disease. Study duration for each subject participating in the placebo-controlled research study will be approximately 12 months (up to a 3 months Screening Period, Baseline visit (1 month), 6 months of placebo or emtricitabine dosing, and 1 month follow-up). Participants will have up to 2 months to complete all procedures for the month 6 study visit.

The main purpose of this study is to evaluate the safety and efficacy of donanemab in participants with preclinical Alzheimer's Disease (AD).
