Alzheimer's Disease Paid Clinical Trials in Missouri

This is an open label study to compare three new generation TAU radioligands, 18F-RO948 (formerly known as 18F-6958948), 18F-MK6240, and \[18F\]GTP1for imaging of taupathy and demonstrate their absence of off-target binding in patients with Alzheimer disease (AD) and older healthy controls (OC). The study will directly compare AD and OC with these three next-generation TAU radioligands and compare each of them with historical data of the current most widely used first generation radioligand, 18F-AV1451. Upto38 (30 AD (Amyloid +)and 8 OC (Amyloid -), matched for age and sex with A+ subjects) male and female subjects aged 50-100 will be enrolled in this study protocol: up to 8 for Cohort 1, up to 8 for Cohort 2, and up to 22 for Cohort 3. The study consists of three cohorts: Cohort 1: Up to8 AD subjects (A+; CDR 0.5 and 1)will receive two PET scans in random order, with receiving either18F-RO948 or18F-MK6240 at the first scan. A third scan with 18F-GTP1is possible, depending on timing and radiotracer availability Cohort 2:Up to8 OC (A-; CDR=0)subjects will receive two PET scans in random order, with receiving either18F-RO948or 18F-MK6240 at the first scan. A third scan with 18F-GTP1is possible, depending on timing and radiotracer availability Cohort 3:Up to 22 (A+; CDR = 0, .5 and 1) subjects will receive three PET scans in random order, with receiving 18F-RO94818F-MK6240 or18F-GTP1at the first scan. Efforts will be made to include about 1/3 CDR = 0, 1/3 CDR .5, and 1/3 CDR 1 in Cohort 3. Read Less

The purpose of this study is to assess the safety, tolerability, immunogenicity and pharmacodynamic effects of ACI-24.060 in subjects with prodromal Alzheimer's disease and in non-demented adults with Down syndrome. Read Less

High body fat at midlife, as evidenced by overweight or obese body mass index (BMI), is increasingly understood as a risk factor for Alzheimer's disease. However, the underlying processes and mechanisms that may underlie this risk remains unknown. With this project, the Investigator proposes to create a new cohort of cognitively normal 120 midlife individuals, age 40-60 years. The investigator and research staff will characterize the participant's overweight or obese status using metabolic tests including, an oral glucose tolerance test, fasting plasma insulin, fasting plasma glucose, and hemoglobin A1c measurements. This testing will generate categories of metabolically abnormal overweight and obese (MAOO), metabolically normal overweight and obese (MNOO), and metabolically normal lean participants (MNLP). Research staff will evaluate differences between these groups on neuroimaging with the newer classification framework of Alzheimer's biomarkers with amyloid (A), tau (T), and neurodegeneration (N), or ATN. Neurodegeneration will be assessed by atrophy on brain MRI as reflected by regional volumes on Freesurfer. Staff will also evaluate MR neuroimaging markers for neuroinflammation using a newer method called diffusion basis spectrum imaging (DBSI), developed at the Mallinckrodt Institute of Radiology at Washington University in St. Louis in collaboration with The Charles F. and Joanne Knight Alzheimer's Disease Research Center (Knight ADRC).

The purpose of this research study is to determine the safety of a radiotracer 18F-Fluselenamyl using positron emission tomography (PET) imaging. The investigators will first complete whole-body PET dosimetry studies in healthy adult normal volunteers to calculate the actual radiation dose of each human organ and determine the allowable dose for a human subject when receiving a single dose for a PET scan. Second, imaging of the brain and neck will be completed in a wide range of ages of healthy adult normal control participants and participants with mild cognitive impairment, both male and females to characterize 18F-Fluselenamyl uptake in the brain, its binding to beta-amyloid plaques, and radiolabeled metabolite will be completed. Amyloid is a protein related to dementia of Alzheimer's disease. 11C-PIB PET imaging along with MRI will also be completed in the same participants and the data will be compared with 18F-Fluselenmayl. 11C-PIB and 18F-Fluselenamyl both bind to beta-amyloid plaques. Finally, a comparison of the normal control participants to patients with Alzheimer's disease will be completed. Read Less

This study involves a brain positron emission tomography (PET) scan with a new, investigational radioactive tracer called \[11C\]-CS1P1 to identify inflammation in the brain by testing with healthy older adults and with cognitively impaired older adults. Read Less

The purpose of this research study is to evaluate adult children of parents with and without Alzheimer's disease which represent an ideal population for investigating the biological changes that precede the clinical onset of AD. The investigators will be imaging the brain to detect the presence of amyloid deposits (plaques in the brain). Amyloid is a protein that may be related to dementia of Alzheimer's disease (DAT).
