Goal Setting to Promote Physical Activity Adherence in Midlife Adults

Physical Activity ยท Exercise

Engaging in regular physical activity during midlife is a key lifestyle behavior associated with reduced risk for Alzheimer's disease and related dementias (AD/ADRD). Yet nearly half of midlife adults (48%) do not meet national physical activity guidelines. The purpose of this mechanistic trial is to identify effective goal setting techniques to enhance psychosocial processes of self-regulation for the successful promotion of PA and adherence to national PA guidelines among midlife adults, with the long-term goal of reducing AD/ADRD risk

Study of LHP588 in Subjects With P. Gingivalis-Positive Alzheimer's Disease

Alzheimer Disease ยท Alzheimer Disease Due to P. Gingivalis

This study is to test LHP588 in persons who have mild to moderate Alzheimer's disease (AD) who have shown progressive mental decline in the last year and who have P. gingivalis (Pg) infection. P. gingivalis infection has been linked to the development of dementia. LHP588 is designed to target the P. gingivalis bacterium, to potentially help to halt or slow down the progression of AD and its symptoms. A saliva test will be done to determine P. gingivalis infection. Tests for AD include standard questionnaires such as MMSE and a blood test for pTau217. Treatment will be blinded, meaning the participant and the doctor will not know if the participant is receiving LHP588 or placebo. The total time for participation in the study may be up to 64 weeks. This includes a screening period (to ensure the participant is suitable for the study and the study is suitable for the participant) of up to 12 weeks, a treatment period of up to 48 weeks, and a safety follow-up period of 4 weeks after the last dose of the study drug to check the participant's overall health. Treatment is a once-a-day capsule. Caregiver participation is required. The study requires the participant to visit the study center (with the caregiver) at least 20 times within 64 weeks (this does not include any unplanned visits that may be recommended by the study doctor). In addition, the study doctor or clinic staff will contact the participant via phone at least 1 time.

Determinants of Incident Stroke Cognitive Outcomes and Vascular Effects on RecoverY

Ischemic Stroke ยท Intracerebral Hemorrhage ยท Subarachnoid Hemorrhage

The overall goal of the DISCOVERY study is to better understand what factors contribute to changes in cognitive (i.e., thinking and memory) abilities in patients who experienced a stroke. The purpose of the study is to help doctors identify patients at risk for dementia (decline in memory, thinking and other mental abilities that significantly affects daily functioning) after their stroke so that future treatments may be developed to improve outcomes in stroke patients. For this study, a "stroke" is defined as either (1) an acute ischemic stroke (AIS, or blood clot in the brain), (2) an intracerebral hemorrhage (ICH, or bleeding in the brain), (3) or an aneurysmal subarachnoid hemorrhage (aSAH, or bleeding around the brain caused by an abnormal bulge in a blood vessel that bursts). The investigators hypothesize that: 1. The size, type and location of the stroke play an important role in recovery of thinking and memory abilities after stroke, and pre-existing indicators of brain health further determine the extent of this recovery. 2. Specific stroke events occurring in individuals with underlying genetic or biological risk factors can cause further declines in brain heath, leading to changes in thinking and memory abilities after stroke. 3. Studying thinking and memory alongside brain imaging and blood samples in patients who have had a stroke allows for earlier identification of declining brain health and development of individualized treatment plans to improve patient outcomes in the future.

A Study of Neurodegeneration and Neuronal Fluctuations in Lewy Body Disease and Alzheimer's Disease

Lewy Body Disease ยท Alzheimer Disease ยท Healthy

The purpose of this research study is to investigate how the brain, memory, thinking, and motor behavior change both in individuals with movement and/or cognitive disorders, as well as healthy individuals. Researchers will look at measurements of memory, thinking, brain wave and muscle activity, daily functioning, and brain scans to learn more about brain disorders such as Alzheimer disease and Lewy body disease.

PROMIS and Mobility Evaluation in Sarcoma Patients

Sarcoma ยท Giant Cell Tumor of Bone

The goal of this is to validate the Patient-Reported Outcomes Measurement Information System (PROMIS) in sarcoma patients undergoing surgery, and to evaluate a novel smartphone app for collecting mobility data. The goals of the study include to: 1. Validate PROMIS as a patient outcome measure in sarcoma 2. Assess the effectiveness of a novel app for administering questionnaires and collecting mobility metrics 3. Compare PROMIS scores and mobility metrics to better evaluate recovery trajectories after surgery Participants will complete PROMIS questionnaires at regularly scheduled intervals using the smartphone app. Questionnaires will be completed pre-operatively and at 6 weeks, 12 weeks, 6 months, and 12 months post-operatively. Additionally, the app will passively track mobility metrics such as daily step count, stairs climbed, and gait parameters to compare with PROMIS scores.

A Study to Assess Efficacy and Safety of KarXT for the Treatment of Psychosis Associated With Alzheimer's Disease (ADEPT-2)

Psychosis Associated With Alzheimer's Disease

This is a Phase 3, randomized, double-blind, placebo-controlled, parallel group study to evaluate the safety and efficacy of KarXT in male and female subjects who are aged 55 to 90 years and have mild to severe Alzheimer's Disease (AD) with moderate to severe psychosis related to AD. The primary objective of the study is to evaluate the efficacy of KarXT compared with placebo in the treatment of subjects with psychosis associated with AD as measured by the Neuropsychiatric Inventory-Clinician (NPI-C): Hallucinations and Delusions (H+D) score.

Repurposing Siponimod for Alzheimer's Disease

Alzheimer Disease ยท Mild Alzheimer Disease ยท MCI With Increased Risk for Alzheimer Disease

Collaboration with multiple sclerosis (MS) specialty colleagues led us to formulate the central hypothesis that Siponimod could lower the rate of brain atrophy in Alzheimer's disease (AD) subjects. To test our central hypothesis, we will carry out an 18-month Phase II, double-blind, randomized, twoarmed, placebo controlled, proof-of-concept clinical study in early AD subjects (i.e. mild AD) who will be receiving an escalating dose of Siponimod or placebo in the ratio 2:1 for 12 months, followed by a 6-month washout period. The primary outcome measures are safety and tolerability of Siponimod in mild AD subjects. The secondary outcome measures are the rates of brain atrophy derived from volumetric MRI (vMRI) as a proxy for neurodegeneration conducted at baseline, 6, 12, and 18 months. The tertiary outcome measures are the changes in cognition and the levels of AD-associated (e.g., Aฮฒ and tau) and inflammatory biomarkers in CSF after Siponimod exposure. In an exploratory effort, we will also measure plasma inflammatory markers during the entire duration of the study to investigate whether one or more of these markers can be used as dynamic surrogate markers of treatment response. Using our unique experience with the repurposing of immunomodulatory drugs for AD (and NCT #04032626), in the present project we are using elements of clinical trial design that we believe were successful and made some adjustments to fit the pharmacologic and toxic properties of Siponimod.

Alzheimer's Prevention Registry: A Program to Accelerate Enrollment Into Studies

Alzheimer's Disease ยท Dementia

The Alzheimer's Prevention Registry (www.endALZnow.org) will collect contact and demographic information on individuals. The objective is to provide information the latest news and advances in Alzheimer's prevention research, and to inform enrollees about research studies in their community. Enrolled individuals will receive regular email communications. As research studies become available, individuals will be notified via email with information as to how proceed should they be interested. Registry enrollees are under no obligation to participate in a research study. Study opportunities may include surveys, healthy lifestyle interventions (e.g., diet, exercise), memory \& thinking tests, brain scans, and investigational drug trials. To join the Registry, please visit www.endALZnow.org
