Active clinical trials for "Alzheimer Disease"

This study consists of 2 periods: [1] Study Period A - evaluating the efficacy and safety of Crenezumab versus Placebo in participants who carry the PSEN1 E280A autosomal-dominant mutation and do not meet the criteria for mild cognitive impairment due to AD or dementia due to AD and are thus, in a preclinical phase of AD. Participants will be randomised in a 1:1 ratio to receive either Crenezumab or Placebo subcutaneously (every 2 weeks) or intravenously (every 4 weeks) for at least 260 weeks. A cohort of participants (non-mutation carriers) will also be enrolled and will be dosed solely on Placebo and [2] Study Period B - Participants will be offered the opportunity to continue to receive study drug until the results of the study are known and post trial access to Crenezumab is started or development of Crenezumab is discontinued.

To compare the efficacy of flexible dosing of brexpiprazole with placebo in subjects with agitation associated with dementia of the Alzheimer's type

The purpose of this study is to evaluate the safety and efficacy of NIC5-15 in the treatment of Alzheimer's Disease.

There are few pharmacological treatments available for Alzheimer's disease, including drugs called cholinesterase inhibitors: donepezil, galantamine, and rivastigmine. In research trials, cholinesterase inhibitors have been shown to improve memory and problem behaviours in people with mild to moderate Alzheimer's disease. However, these benefits may not extend to the real-world when taking into account nursing home and health care costs. There is less information on the use of cholinesterase inhibitors in people with severe Alzheimer's disease. In Canada, only donepezil is recommended for the treatment of severe Alzheimer's disease. However, there is no information on whether the benefits that donepezil provides to people with severe Alzheimer's disease are sustained over the long term. Moreover, while the tolerability of cholinesterase inhibitors is generally acceptable, their use is not completely harmless. Common side effects include nausea, diarrhea, insomnia, vomiting, muscle cramping, fatigue and loss of appetite. In Ontario, cholinesterase inhibitor users tend to remain on these medications for two years or more and often until death. The current cholinesterase inhibitor guidelines provide details on what medication should be used, when it should be started and how it should be monitored, but there is less clarity on when it is safe and appropriate to stop treatment. The cessation of cholinesterase inhibitors in patients no longer appearing to display any clear benefits may help to lower the risk of unpleasant side effects, lower the use of multiple medications, and reduce the costs of caring for individuals with Alzheimer's disease. However, the cessation of cholinesterase inhibitor therapy may run the risk of deterioration in memory, worsening or development of behavioural symptoms and the placement of additional demands on professional and unpaid caregivers. There is a clear need for guidelines when to stop cholinesterase inhibitor treatment, especially for patients in whom the benefits of not be on the medication will outweigh the risks. The purpose of this study is to address this issue by collecting data which may be helpful in predicting which types of patients may benefit from stopping cholinesterase inhibitor treatment. Understanding when, and for whom, it is appropriate to stop cholinesterase inhibitor treatment will influence the field of pharmacology in the treatment of Alzheimer's disease.

The primary objective of this feasibility study is to evaluate the safety of DBS-f in patients with mild Alzheimer's disease by assessing all device and/or therapy related adverse events. The secondary objective is to preliminarily estimate the treatment effect size on the outcomes of interest at 12 months post-randomization. The objectives do not involve formal tests of hypotheses.

The study will examine the effects of intranasally administered long-acting insulin detemir on cognition in persons with Alzheimer's disease (AD) or amnestic mild cognitive impairment (aMCI). The rationale for these studies is derived from growing evidence that insulin contributes to multiple brain functions, and that insulin dysregulation can contribute to AD pathogenesis. Thus, therapies aimed at restoring normal insulin signaling in the CNS may have beneficial effects on brain function. Intranasal administration of insulin increases insulin signaling in the brain without raising peripheral levels and causing hypoglycemia. Insulin detemir is an insulin analogue that may have better action in brain than other insulin formulations because of its albumin binding properties. The investigators will test the therapeutic effects of intranasally-administered insulin detemir in a study in which participants will receive insulin detemir, regular insulin, or placebo over a four month period. The investigators will test the hypothesis that insulin and insulin detemir will both improve memory and daily functioning in persons with AD/aMCI compared with placebo, but that insulin detemir will have the greatest effect.

To evaluate the tolerability, safety and efficacy of 3-step titration versus 1-step titration of Rivastigmine patch in the Japanese population.

Regular physical activity is now recognized as a key element of good physical and mental health and this all ages. MAIN GOAL : Evaluate the effectiveness of physical training associated with a cognitive training in improving the cognitive function of patients diagnosed with Mild Cognitive Impairment (MCI). DESIGN : Controlled randomized monocentric and prospective study with clinical benefit for the patient with three groups : one physical training and cognitive exercise group, one physical training without cognitive exercise group and one control group. In agreement with the literature on the effects of physiological stress on cognitive performance, the investigators expect the best cognitive test scores in groups with exercise training compared with controls (35% versus 80% error), and better scores on the MMSE, IALD, depression Scale, Index of Pittsburg sleep quality and quality of Life Questionnaire. Furthermore the investigators hypothesize that this positive effect is greater in the physical training and cognitive exercise group compared with the physical training group only.

This first-time-in-man study is mainly designed to assess the safety and tolerability of AADvac1 in the treatment of Alzheimer's disease. AADvac1 is a vaccine directed against pathologically modified Alzheimer tau protein that is the main constituent of neurofibrillary tangles (NFTs), and is intended to be a disease-modifying treatment for Alzheimer's disease, i.e. to halt its progress. As this study is a Phase I study focused on tolerability and safety, efficacy will be assessed in an exploratory manner.
