Filter by:This is a Phase 1, first-in-human (FIH), double-blinded, placebo-controlled study where healthy subjects are randomly allocated to receive APNmAb005 or placebo. Approximately 5 dosing groups (cohorts) are planned with 8 subjects (randomized to 6 active: 2 placebo) per cohort. the starting dose of APNmAb005 is 5 mg/kg and the anticipated doses for subsequent cohorts are 10, 25, 50 and 70 mg/kg. A Safety Review Team (SRT) will review data on an ongoing basis throughout the study and before progression to the next dose level cohort. Subjects will receive a single dose of either APNmAb005 or placebo administered as a single IV infusion on Day 1 of the study and will remain in the study center until Day 3 (48 hours after dosing). They will return to the study center for 7 outpatient visits. The duration of the study, excluding screening, is approximately 71 days.
The primary objective of this study is to verify the clinical benefit of monthly doses of aducanumab in slowing cognitive and functional impairment as measured by changes in the Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) score as compared with placebo in participants with early Alzheimer's disease.
Double-blind, randomized, placebo-controlled pilot study in mild to moderate AD patients to assess the effects of treatment with ECHS AD pulsed electromagnetic treatment device on disease progression. Enrolled patients will be randomized to active or sham device group. They will treat themselves at home three times a day for 15 minutes over 120 days. Primary end points are the The Alzheimer's Disease Assessment Scale-Cognitive Subscale and the Mini-Mental State Exam. Participants will be followed-up for 9 months post-treatment.
The purpose of this study is to determine how feasible it is to deliver an online course to reduce out-of-pocket costs of caregiving and reduce financial stress among Latino family caregivers to a family member living with dementia. The investigators hope that that the results of this study will help to reduce high these out-of-pocket costs and improve financial wellbeing for Latino family caregivers. Caregivers will be asked to to participate in 3 online surveys, in addition to participating in 5, 1.5 hour group-based Zoom learning sessions.
This is a randomized, pragmatic clinical trial to evaluate the effectiveness of a collaborative care-coordination program embedded in a health plan for people living with Alzheimer's disease and related dementias (ADRD) and their care partners versus usual care. The study population will include community-dwelling Medicare Advantage members living with ADRD and their care partners. Outcomes will be healthcare utilization outcomes of individuals with ADRD and include emergency department visits, outpatient visits, avoidable emergency department visits, and admission to long-term care facilities.
Randomized efficacy and safety study of piromelatine 20 mg versus placebo in participants with mild dementia due to Alzheimer's disease (AD) who are 2:107,510,000-107,540,000 polymorphism non-carriers with the primary objective to compare the effect of piromelatine to that of placebo on the AD Assessment Scale cognitive subscale (ADAS-cog14) at Week 26 of double-blind treatment.
The specific aim of the pragmatic trial is to evaluate the practical utility and effect of the PDM, the QDRS, and the combined approach (PDM + QDRS) in improving the annual rate of new documented ADRD diagnosis in primary care practices.
The investigator has shown that improved cardiorespiratory fitness following an aerobic exercise program elicits cognitive benefit in elderly subjects and memory improvement in Alzheimer's disease (AD). The physiological mechanism may be related to exercise-mediated change in circulating factors that permeate the brain. The response to each individual bout of exercise (i.e. the acute exercise response) may differ between subjects and be key to driving brain benefit. In young populations, the acute response to exercise can last hours and affect brain glucose metabolism. However, the field knows little about this acute exercise response in AD. Most exercise intervention trials designed to prevent and slow AD, including our own (AG033673; AG034614; AG043962; AG049749; AG053952), assess biomarkers at two fasting time points: pre- and post-intervention. The acute exercise response in the brain and periphery likely varies between subjects and diagnoses and provide key information regarding mechanisms of benefit. Our primary goals are to characterize the acute exercise response to exercise in the brain (glucose metabolism) and periphery (biomarker response) in aging and AD. The investigator will identify relationships between exercise-related factors (i.e. heart rate, biomarkers) and change in brain metabolism and cognition. Understanding these mechanistic relationships will provide specific targets that can be used in future trials to develop individualized exercise prescriptions and maximize benefit. Accumulating evidence suggests that the exercise-related metabolite lactate is an understudied effector of brain health. Lactate is an essential fuel for neuronal function. It is supplied to neurons through glucose metabolism in nearby glia and from peripheral blood, since the brain is permeable to lactate. A drop in cerebral glucose metabolism is a marker of AD. Thus, supplying neurons directly with lactate for oxidation may supplement energy requirements in AD, as has been suggested with ketones. Importantly, circulating lactate levels rise during exercise. Repeated increases in systemic lactate (acute exercise response) may transiently spare glucose by providing an alternative fuel. With routine exercise, acute responses may elicit adaptations that facilitate the use of lactate beyond that which occurs during acute exercise and contribute to brain benefits observed during chronic exercise interventions. In younger populations, higher exercise intensity evokes a greater lactate response compared to lower intensities and elicits cognitive benefit. The investigator will achieve these goals through the following aim: Aim 1. Examine differences in lactate metabolism between diagnosis groups and the effect of lactate on cognitive performance. Increased blood lactate can reflect increased production or decreased uptake. This has never been compared in ND and AD. The investigator will use a "lactate clamp" procedure, where lactate is infused to concentrations that match those found during exercise, to characterize lactate turnover. The investigator will characterize cognitive performance following lactate infusion, independent of exercise factors. The investigators hypothesize that ND subjects (n=12) will use lactate more efficiently (greater uptake) than AD individuals (n=12). The investigator further hypothesize that cognitive performance will acutely improve after lactate infusion in ND and AD subjects. The overall goal is to characterize lactate metabolism, and its relationships with cognition. The KU ADC is a recognized leader in the study of exercise and metabolism in aged and AD populations, and puts the investigator in a strong position to successfully achieve these aims.
The current study is being conducted by the Sponsor to evaluate the efficacy and safety of GV1001 (0.56 mg and 1.12 mg) administered subcutaneously as a treatment for mild to moderate Alzheimer's disease (AD). Studies using in vivo and in vitro AD models have shown that GV1001 inhibits neurotoxicity, apoptosis, and the production of reactive oxygen species induced by amyloid beta (Aβ) in neural stem cells by mimicking the extra-telomeric functions of human telomerase reverse transcriptase (hTERT). In nonclinical studies, using both mild (early stage) and severe (late stage) AD mouse models, GV1001 was shown to improve cognitive function and memory, as well as significantly reduce the amount of Aβ and tau proteins. The multifunctional effect of GV1001 makes it a promising therapeutic option for the treatment for AD. In a completed Phase 2 study conducted in Korea, GV1001 showed significant improvement in change from baseline of Severe Impairment Battery score at Week 24 and demonstrated a clinically acceptable safety profile in patients with moderate to severe AD.
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.
