Alzheimer's Disease Paid Clinical Trials in Missouri

This is an open label study to treat dominantly inherited Alzheimer's disease (DIAD) mutation carrier participants from the DIAN-TU-001 gantenerumab Open Label Extension (OLE) period with lecanemab to determine the effects of amyloid removal on age of onset and clinical progression compared to external controls, if amyloid plaque as measured by amyloid PET can be fully removed in DIAD, and the effects of amyloid removal on biomarkers of disease progression.

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. Read Less

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.

The purpose is to evaluate the biomarker effect, safety, and tolerability of investigational study drugs in participants who are known to have an Alzheimer's disease (AD)-causing mutation. Stage 1 will determine if treatment with the study drug prevents or slows the rate of amyloid beta (Aβ) pathological disease accumulation demonstrated by Aβ positron emission tomography (PET) imaging. Stage 2 will evaluate the effect of early Aβ plaque reduction/prevention on disease progression by assessing downstream non-Aβ biomarkers of AD (e.g., CSF total tau, p-tau, NfL) compared to an external control group from the DIAN-OBS natural history study and the DIAN-TU-001 placebo-treated participants.

The goal of this clinical trial is to learn if buntanetap/Posiphen works to treat early Alzheimer's disease in adults aged 55-85. It will also learn about the safety of buntanetap/Posiphen. The main questions it aims to answer are: * Does buntanetap/Posiphen improve cognition as measured by ADAS-Cog13? * Does buntanetap/Posiphen improve function as measured by ADCS-iADL? * What medical issues do participants have, if any, when taking buntanetap/Posiphen? Researchers will compare buntanetap/Posiphen to a placebo (a look-alike substance that contains no drug) to see if buntanetap/Posiphen works to treat early Alzheimer's disease. Participants will: * Take buntanetap/Posiphen or a placebo every day for 18 months * Visit the clinic periodically for checkups, tests, and questionnaires (screening visits, enrollment, month 1, month 3, month 6, month 9, month 12, month 15, month 18), including a volumetric MRI at month 6 and month 18 * Complete pre- and post-clinic visit phone calls Read Less

The purpose of this study is to measure the difference in time to developing or worsening memory, thinking, or functional problems due to Alzheimer's disease occurring in participants receiving study drug compared to placebo. Participation could last up to 255 weeks including screening, a double-blind treatment period, and a double-blind observation period. In addition, eligible participants who receive placebo during the double-blind treatment period may choose to extend their study participation to receive open-label remternetug in an extension period.

The purpose of this study is to evaluate the efficacy and safety of KarXT + KarX-EC in adult participants with agitation related to Alzheimer's Disease. Read Less

The purpose of this study is to identify potential biomarkers that may predict the development of Alzheimer's disease in people who carry an Alzheimer's mutation. Read Less

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.

The primary objective of the proposed research is to investigate the promise and underlying mechanisms of mindfulness training as a preventative lifestyle intervention to enhance cognitive health in Latinx older adults, thereby mitigating risk of Alzheimer's Disease (AD) in a population that may be particularly vulnerable.

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 main purpose of this study is to evaluate the safety and efficacy of donanemab in participants with preclinical Alzheimer's Disease (AD). Approximately 800 additional participants will be enrolled in a 12-month addendum to assess safety of a different titration regimen. Read Less
