Active clinical trials for "Alzheimer Disease"

The aim of this study is to evaluate the safety, feasibility, tolerability and efficacy of a new buccal film of montelukast in patients with mild to moderate Alzheimer's disease.

Evaluation of central nervous system penetration of orally administered Rapamune (RAPA) in older adults with Mild Cognitive Impairment (MCI) or early Alzheimer's disease (AD) and investigate associated safety, tolerability, target engagement, cognition, and functional status as initial proof-of-concept study

This is a phase 2B multicenter, randomized, double-blind, placebo-controlled, parallel group dose finding study to evaluate the safety, tolerability and efficacy of PQ912, an inhibitor of the glutaminyl cyclase enzyme, in 250 subjects with mild cognitive impairment and mild dementia due to Alzheimer 's Disease.

Sodium Oligomannate Capsules (GV-971) has been approved for treatment of mild to moderate Alzheimer's disease and improving the cognitive function of patients. This study plans to observe, in the clinical patients, the long-term efficacy and safety of GV-971, as well as the changes in blood and gut microbiota biomarkers after treatment, to validate the mechanism of action of GV-971, in order to better guide the rational use of drug in clinical practice.

A 76-week safety and efficacy study of simufilam (PTI-125) given twice daily to participants with mild-to-moderate Alzheimer's disease (AD) for 76 weeks. Approximately 1083 participants will be randomized (1:1:1) to receive either placebo, 50 mg tablets of simufilam, or 100 mg tablets of simufilam, twice daily, for 76 weeks. Clinic visits will occur 4 weeks after the baseline visit, and then every 12 weeks until the end of the study. The safety of simufilam, and its efficacy in enhancing cognition and slowing cognitive and functional decline will be evaluated.

The investigator will investigate how light delivering 40 hertz (Hz) affects subjective sleep and cognition in a controlled laboratory study. A lab study will allow the collection of electroencephalogram (EEG) data, perform cognitive tests, and observe the response in those with mild cognitive impairment (MCI) compared to a healthy control group (HC). Participants will attend two study sessions over the course of two weeks. During both sessions, all participants will experience 10 minutes of a low-level light, followed by a data collection period which involves a sleepiness rating, an electroencephalogram (EEG) recording, and a computerized memory test. Participants will then experience either a RL or a placebo RL condition for one hour, after which there will be a second data collection.

U.S. multicenter, parallel group study designed to evaluate the safety and efficacy of oral 20 mg twice daily (BID) NE3107 vs placebo in 400 adult subjects with mild to moderate probable AD. Single primary endpoint (Clinical Dementia Rating Scale Sum of Boxes, CDR-SB) will be evaluated as the change from Baseline to Week 30. Secondary endpoints include measures of cognition, neuropsychological deficits, functional performance, and glycemic control. A subset of patients may volunteer for exploratory magnetic resonance imaging (volumetric changes) and positron emission tomography (cortical glucose metabolic rate) scans at baseline and week 30.

The main goals of this study are to further determine whether the study drug donanemab is safe and effective in participants with Alzheimer's disease and to validate video scale assessments.

The goal of this non-randomized clinical trial is to assess the effects of strength training in the physical function of Alzheimer's disease (AD) patients. The main question it aims to answer are: Is a basic strength training enough to improve physical function in AD patients? Is an exercise intervention able to delayed the progression of the disease? Is an AMRAP intervention feasible in AD patients? Participants in the exercise group will perform a 16-weeks program divided in two phases (phase 1: basic strength training; phase 2: AMRAP training). Participants in both (exercise and control) groups will receive their usual care treatments which include occupational therapy, musicotherapy, cognitive stimulation and sensory stimulation.

The goal of this clinical trial is to test the effects of different types of exercise on brain health and Alzheimer's risk in older African Americans. Specifically, the main question[s] it aims to answer are: What is the effect of a Cardio-Dance Fitness (CDF) vs. a Strength, Flexibility, and Balance (SFB) intervention on a cognitive marker of Alzheimer's risk, generalization? What is the effect of the CDF vs. SFB intervention on a fMRI biomarker of Alzheimer's, neural flexibility, and do improvements in neural flexibility mediate improvements in generalization? Do ABCA7 genotypic variations moderate the efficacy of the CDF vs. SFB intervention for reducing Alzheimer's risk? Participants will undergo-- at baseline and post-test-- health assessments, cognitive tests, and structural and functional magnetic resonance imaging (fMRI), and a blood-draw to assess Alzheimer's risk biomarker levels.
