Active clinical trials for "Alzheimer Disease"

Study to Evaluate the Safety and Tolerability of Oral CT1812 in Subjects with Mild to Moderate Alzheimer's Disease.

This is a single-site, randomized, double-blind, placebo-controlled, 29-day, 2-period crossover Phase 2 study of 1 dose level of CT1812 (active) or placebo in adults with mild to moderate AD.

A randomized, double-blind, placebo-controlled, single dose escalation phase 1 study to access the Pharmacokinetics and Pharmacodynamics of Single Intravenous Administration of SHR-1707

This was a randomized, single-blind, parallel, placebo-controlled clinical trial assessing the efficacy of neuronavigational TBS among patients with AD. Fourty late-onset AD were included in the study, all the patients were divided into TBS groups and drug treatment group. Drug intervention group AD patients with drug regimen (donepezil 5mg / d) and primary care guidance, once every three months follow-up. TBS group is treated with TBS (a course of treatment every 3 months); after completing 4 treatments/follow-ups a year, evaluate the changes in MoCA, other clinical symptoms and multi-domain cognition tests, and brain Changes in structure and function.

This randomized clinical trial on 60+ aged and independent-living healthy individuals with symptoms of insomnia will attempt to improve sleep and health outcomes related to sleep with enhancement of a clinical intervention, Cognitive Behavioral Therapy for Insomnia (CBTi).

Dementia is a term for the impaired ability to remember, think, or make decisions that interferes with doing everyday activities. Alzheimer's disease is the most common type of dementia. Though dementia mostly affects older adults, it is not a part of normal aging. This study aims to assess the role of volumetric MRI in evaluation of different types of dementia.

Alzheimer's disease (AD) is the main cause of dementia. At present, AD is incurable. Cholinesterase inhibitors, especially donepezil, are the first choice for mild and moderate AD. Sodium oligomannate (GV-971) is a marine-derived oligosaccharide. It is proposed that it can reconstitute the gut microbiota, and inhibit neuroinflammation in the brain as observed in animal models. It reduces Aβ deposition in the brain of Aβ-transgenic mice. The reduction in both Aβ deposition and neuroinflammation may synergistically contribute to the improvement of cognitive impairment and delay the progress of the disease. The State Food and Drug Administration of China (SFDA) approved it for the treatment of mild to moderate AD in 2019. Due to the different mechanism of cholinesterase inhibitor and GV-971, theoretically, they may synergistically improve cognitive function and delay disease progression. They are also used in patients with AD, but there is a lack of data on their effectiveness and safety. Therefore, the purpose of this observational study is to compare the efficacy and safety of donepezil and GV-971 monotherapy and combination therapy in patients with mild and moderate AD, which is of great significance for guiding the treatment of mild and moderate AD.

Annovis is conducting a clinical study to investigate Posiphen in patients with Early Alzheimer's Disease (AD) and Early Parkinson's Disease (PD). Investigators are looking to recruit 68 patients in two parts of the study. In Part one of the study Investigators will recruit 14 AD and 14 PD patients who will either receive placebo (an inert pill which looks like the study drug) or the study drug Posiphen, both taken daily. In Part two of the study Investigators will recruit 40 PD patients who will receive different strengths of the study drug Posiphen taken daily. Patients will be required to come to the site for 3 face to face visits and have 4 phone calls, tests include but are not limited to, blood and CSF (spinal fluid) sampling, cognitive assessments, clinical examinations and laboratory safety tests. Primarily the Investigators are looking for the safety and tolerability of Posiphen, although Investigators will also evaluate the activity of Posiphen by a number of different biomarkers measuring pathway and target engagements.

Alzheimer's disease and related dementias (ADRD) are leading causes of disability and often result in communication deficits of the person with dementia (PWD) that can complicate ADRD caregiving and clinical care. The research team will work with stakeholders to develop and design a personalized Assistive and Alternative Communication (AAC) device that relies on information technology (IT) and touchscreens to promote communication and personhood for PWD about their care preferences and experiences. This study will integrate the AAC into an existing health IT intervention that already facilitates clinical communication between caregivers and providers of PWD, called CareHeroes (CH). A clinical trial will be conducted to evaluate outcomes of 120 triads (PWD/caregivers/providers) utilizing the CH intervention as an adjunct to care and caregiving for 12 months.

Patients with Alzheimer's disease (AD) can have seizures in addition to losing their memory and other mental functions (referred to as cognitive functions). The seizures, and other examples of overactive electrical activity in the brain that is not noticeable, contribute to the loss of cognitive function. Studies in animal models of AD suggest that a drug that prevents seizures called levetiracetam may reduce neuronal over-excitation and improve cognition. Based on this evidence, the investigators propose to determine if levetiracetam can be used to treat patients with AD. The investigators developed novel instruments for this population that will also be used in future large-scale clinical trials. The current study will last for 12 weeks and will involve people with AD. Participants will be initially examined with an overnight brain wave study to assess for silent epileptic (seizure-like) activity. Presence of epileptic activity on the screening exam is not required to enter the trial. Participants will then be assigned to groups in a randomized manner. One group will receive levetiracetam for 4 weeks, then no drug for 4 weeks, and then placebo for 4 weeks. For another group, the order of treatments will be reversed. The cognitive abilities of participants will be retested every 4 weeks and compared to those at the beginning. The cognitive tests include a virtual-reality navigation test of memory and computerized tests of mental flexibility and problem solving. The participants will be monitored with a magnetoencephalogram (MEG) with simultaneous EEG (M/EEG) at each visit. M/EEG is a highly effective non-invasive method for identifying brain regions of epileptic activity. The investigators will need to recruit 36 randomized participants to test the study hypotheses. This study will take place at the University of California, San Francisco (UCSF) and the University of Minnesota.
