Active clinical trials for "Alzheimer Disease"

The purpose of the study is to evaluate the safety and tolerability of ascending oral doses of CHF 5074 after prolonged administration to patients with mild cognitive impairment.

Current therapeutic approaches for the treatment of neurodegenerative diseases like Alzheimer disease (AD) offer limited and often transient symptomatic benefits to patients but do not mitigate the insidious loss of neuronal cells. In this trial the investigators will evaluate Efficacy and Tolerability of MLC601 as a neuroprotective in Patients with Mild to Moderate Alzheimer Disease who Were Unable to Tolerate or Failed to Benefit from Treatment with Rivastigmine.

This study will test the use of venlafaxine to treat the depression in Alzheimer's Disease. Venlafaxine works by increasing natural substances in the brain (serotonin and norepinephrine) that help maintain mental balance. Alzheimer's disease (AD) is the commonest neurodegenerative disease of aging and the cause of major financial and emotional burden to patients, families and caregivers, and society. Depression is a very common symptom of AD, affecting as many as 50% of patients over their illness. Depression in AD (Alzheimer's disease) contributes greatly to patient disability and caregiver distress. Neither psychosocial interventions nor psychotropic medications have proven effective to date for the treatment of depression in AD.Venlafaxine is approved by the U.S. Food and Drug Administration (FDA) for the treatment of major depression but it is not known whether or not it can help depression in Alzheimer's Disease.

Objective of this study is to evaluate the safety, tolerability, pharmacokinetics and preliminary pharmacodynamic effects of multiple doses of Gantenerumab in subject with mild to moderate AD.

Resveratrol is derived from plants and is found in highest levels in red wine and the skin of red grapes. A recent study reported that monthly and weekly consumption of red wine is associated with a lower risk of dementia. There is compelling evidence that caloric restriction can improve overall health by activating a class of enzymes known as Sirtuins. Resveratrol is a substance found in some plants that directly activates sirtuins, mimicking the effects of caloric restriction and may affect regulatory pathways of diseases of aging, including Alzheimer's disease (AD). In this study, people with AD will be given either Resveratrol or placebo for 12 months to determine whether daily resveratrol therapy is beneficial in delaying or altering the deterioration of memory and daily functioning. Subjects age 50 and above with a diagnosis of probable AD may qualify for participation in this study. A small group of 15 participants will be asked to take part in a more detailed 24-hour Pharmacokinetic (PK) sub-study that will measure resveratrol levels over a 24 hour period.

This study will assess the safety and pharmacodynamics of three different doses of MK-8931, a ß-secretase inhibitor, in participants with mild to moderate Alzheimer's Disease (AD).

The state of the art with regard to the neurodegenerative dementias, especially for Alzheimer´s disease (AD), is that their progression is still irreversible causing cognitive, motor, and behavioral impairment. Although the current pharmacological treatments attenuate cognitive decline in some cases, the majority of treatments does not avoid the motor and functional changes caused by the progress of the disease. Although several studies show that exercise has a positive effect when it comes to the treatment of the disease, some methodological questions affect the application of the training protocols. The use of recognized intensity patterns like maximum oxygen uptake (VO2max) and maximum heart rate (HRmax) percentage to control the training of patients with dementia is still rare in the literature. Therefore, this seems to interfere on the definition of an ideal prescription. Following this line of reasoning, the purpose of the present study is to assess the effect of moderate aerobic exercise on cognition and functional abilities in AD patients. Design: Randomized controlled trial, double-blinded, with 16-week follow-up. Setting: Center for Alzheimer's disease in the Institute of Psychiatry of the Federal University of Rio de Janeiro. Participants: Elderly with Alzheimer disease. Interventions: The patients will be randomly assigned to an exercise group (EG) on a treadmill (30 minutes, twice a week and moderate intensity of 60% VO2max) and a control group (CG). Main outcome measures: Cognitive function will be assessed using CAMCOG, Trail Making Test A, Digit Span, Stroop Test, Rey auditory-verbal learning test and Clock Test, and functional capacity will be evaluated using Berg Balance Scale (BERG), Sit-to-Stand test (STS), functional reach test (FR), and the time to up and go test (TUGT).

The purpose of this study is to evaluate the efficacy and safety of galantamine in patients who failed to benefit from donepezil (patients switching from donepezil). In clinical practice, it is expected that galantamine will be used in patients switching from donepezil due to the insufficient efficacy of donepezil.

This is a phase 2 double-blind, randomized, sham-controlled study to investigate the effects of repeated transcranial direct current stimulation for the treatment of apathy in moderate Alzheimer's Disease in patients selected from an outpatient clinics in São Paulo, Brazil.

The purpose of this Phase II study is to evaluate the safety and tolerability of HF 0220 in patients with Alzheimer's disease compared to placebo (inactive substance). The study will also validate biochemical markers as appropriate clinical end-points and to assess the suitability of chosen dose levels for future clinical studies.
