Filter by:This proof-of-concept study will assess safety, tolerance, and efficacy of NanoLithium® NP03 in patients with mild-to-severe Alzheimer's Disease (AD).
The goal of this study is to investigate whether Low Intensity Focused Ultrasound Pulsation (LIFUP) targeting a part of the brain involved in memory will have an affect on brain activity and whether it may improve memory in people with Mild Cognitive Impairment and Mild Alzheimer's Disease. The main questions the study seeks to answer are: 1. Can LIFUP increase brain activity in the targeted area? 2. Can LIFUP improve memory in people with MCI and mild AD? 3. Can LIFUP improve connectivity of memory networks in the brain? Participants in this study will complete MRIs and memory testing, and receive Low Intensity Focused Ultrasound to a part of their brain involved in memory (the entorhinal cortex).
This is a phase 2, randomized, double-blind, placebo-controlled study of oral EX039 as add-on to Acetylcholine Esterase Inhibitors in subjects with mild Alzheimer's disease.
The study utilizes investigational software, the SPARK Test, with an FDA-cleared electroencephalography (EEG) amplifier and EEG cap to collect and then analyze patient EEG data.
The Arizona Alzheimer's Disease Research Center (ADRC) is the National Institute on Aging's (NIA's) first statewide AD Center (ADC), the only ADC in the Southwestern United States, and a leading example of statewide collaboration in biomedical research. It capitalizes on Arizona's strengths in brain imaging, genomics, computer science and biomathematics, the basic, cognitive and behavioral neurosciences, clinical, and neuropathological studies of AD, the discovery and evaluation of investigational treatments, and the study of normal cognitive aging.
The primary purpose of this long-term follow-up study is to assess the long-term safety profile of APOE4 homozygote participants who were administered gene therapy (LX1001) for the treatment of Alzheimer's disease in Study LX100101. A secondary objective is to assess the biomarker as shown by the conversion of CSF APOE isoforms from APOE4 to APOE2-APOE4. Additional secondary outcomes include amyloid PET scan, CSF markers (including Aβ42, Aβ42/Aβ40 ratio T--tau, and P-tau), and quantitative MRI (and other biomarkers that may be informative for this therapeutic approach). Other secondary objectives include instruments to assess cognitive and clinical AD and to evaluate if treatment with AAVrh.10hAPOE2 improves brain tau pathology with tau PET scan (LX1001-01 Cohort 3 only).
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 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.
This study will be conducted to evaluate the efficacy, safety, tolerability, and pharmacokinetics of masupirdine compared to placebo for the treatment of agitation in participants with dementia of the Alzheimer's type.
This is a Phase 1/2 study to evaluate the safety and tolerability of 18F-OP-801 in subjects with ALS, AD, MS, PD and age-matched HVs. 18F-OP-801 is intended as a biomarker for PET imaging of activated microglia and macrophages in regions of neuroinflammation.
We will conduct a Tau PET scan in cognitively normal older adults, enrolled in the Aging Brain Cohort Dedicated to Diversity Study (ABCD2-Tau) study at the University of Pennsylvania's Penn Memory Center/Alzheimer's Disease Core Center (PMC/ADC).Study duration will generally be a one-day study visit for PET imaging, but all subjects will be followed annually as part of their participation in the ABCD2 study. Findings from this study will likely provide insight into the mechanisms and distinctions of age-related cognitive decline and that of preclinical Alzheimer's Disease.
