Active clinical trials for "Alzheimer Disease"

This is a prospective open comprehensive proof-of-principle pilot study.

To investigate the safety and efficacy of an orally administered dose of TW-012R in patients with Alzheimer's disease bearing PSEN1 (presenilin 1) mutations (PSEN1-AD), using a placebo group as a control. In addition, long-term safety will be examined in an open-label extension trial.

The main objective of the MONANTI study is twofold: Firstly, to determine the amount of the anti-dementia drugs donepezil and memantine in the blood (henceforth mentioned as 'serum level) in a broadly defined clinical population of patients suffering from dementia treated with the two drugs in question. Secondly, to determine whether adjustment of treatment of anti-dementia medication according to serum levels will benefit patients in terms of cognitive performance, quality of life, frequency and severity of side effects. The reason for conduction of this study is that the relationship between serum-level of anti-dementia drugs, clinical efficacy, compliance and side effects has only been scarcely investigated. Both a previously published study and a preliminary (pilot)study conducted imply that roughly 50 % of patients on donepezil have serum-levels outside the recommended interval. Thus, MONANTI will investigate if this is indeed the case in a broadly comprised population of patients suffering from dementia treated with donepezil or memantine. In addition, MONANTI will link serum levels to co-morbidity, level of compliance, medication interactions. It is hypothesized that the efficacy of anti-dementia medication can be significantly improved by adjustment of treatment according to serum levels. Also, it is hypothesized that the burden of side effects can be reduced in patients in whom too high serum levels are detected, if dosage reduction or change of treatment drug is done. MONANTI is a randomized study, in which the assessor is blinded to avoid related biases to the extent possible. To fit the enrollment criteria a patient must be newly diagnosed with either Alzheimer's disease, dementia with Lewy-bodies or Parkinson's disease with dementia and be described treatment with either donepezil or memantine. Also, the patient must not meet a list of (exclusion) criteria, which have been set up in order to avoid blur and biases of the results. Patients can be selected as participators on account of the above, including an informed consent to participation. Next, the participators will randomized be assigned to one of two study arms. In the first of these, the control arm, the participators receive only standard treatment and follow-up at the outpatient clinic, except for measurement of serum level of the anti-dementia medication with which they are treated and a genetic test for a few key genes thought to be relevant for the study (two liver enzymes, two genes linked to Alzheimer's disease). In the other arm, the intervention arm, the participators will be closely monitored for side effects after prescription of anti-dementia drugs. All these participators will be offered a measurement of serum level in case they experience possible side effects within 2 months of treatment initiation. If, not a measurement of the serum level will be done after 6 months. All patients in the intervention arm, will be offered adjustment of their treatment with the anti-dementia drug based upon serum level. To assess the possible effects of treatment adjustment seven clinical scoring tests will be used (MMSE, ACE, clock-drawing test, NPI-Q, DAD, GCI, GDS). Assessment includes symptom severity and level of compliance according to close relatives. To measure the effect of donepezil on brain (cholinergic) function 30 participants will be recruited for electroencephalography (EEG). These participants will have an EEG done at enrollment and after 6 months. In addition to the quantitative part study a qualitative part study with relatives of enrolled patients will be conducted. All the needed approvals have been obtained according to Danish law (approval by the Danish Data Protection Agency, Scientific Ethics Committee for Region Sjaelland, The Danish Medical Agencies).

This is a multi-center, randomized, double-blind, placebo-controlled study, to assess the efficacy and safety of AXS-05 in the treatment of agitation in patients with 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.

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.

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

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.

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).
