Active clinical trials for "Alzheimer Disease"

The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics of KHK6640, given as a single dose and as multiple doses in patients with Prodromal Alzheimer's Disease (AD) or Mild to Moderate AD.

The objective of this trial was to assess the dose-response relationship of symptomatic efficacy of talsaclidine base on ADAScog and to assess safety and tolerability

This study will assess the effects of administration of VX-745 for 12 weeks on amyloid plaque burden in Alzheimer's disease (AD). Subjects who meet entry criteria will undergo 11C-PiB (Carbon-11-labeled Pittsburgh Compound B) positron emission tomography (PET) at baseline and after 45 days of dosing with VX-745. Cognitive testing will also be conducted at baseline and day 45.

This study will assess the effects of VX-745 on markers of disease in the central nervous system of patients with MCI due to AD or with mild AD. The study will also evaluate the safety and tolerability of VX-745 in these patients during 6 weeks of dosing, as well as the plasma and cerebrospinal fluid concentrations of VX-745 during dosing.

Single site, parallel-group, double-blind trial of low or high dose of BI 409306 to evaluate the ocular and systemic safety and pharmacokinetics during 14 day treatment period in patients with schizophrenia, Alzheimer's disease, or age comparable healthy volunteers.

Apathy in Dementia Methylphenidate Trial 2 (ADMET 2) is a Phase III, placebo-controlled, masked, 6 month, multi-center randomized clinical trial sponsored by National Institutes of Aging involving 200 participants with Alzheimer's disease (AD). ADMET 2 is designed to examine the efficacy and safety of methylphenidate as treatment for clinically significant apathy in AD participants. ADMET 2 will enroll participants from real world settings such as outpatient, nursing home, and assisted living facilities and will examine the effects of methylphenidate on apathy and cognition. ADMET 2 will also conduct careful safety monitoring.

This is a Phase 1b, multi-center, randomized, double-blind, placebo-controlled study designed to evaluate the safety, tolerability, and pharmacokinetics of GC021109 in subjects with mild to moderate Alzheimer's Disease (as determined by 2011 National Institute on Aging- Alzheimer's Association [NIA-AA] criteria and Mini Mental State Examination [MMSE]). The Investigator, study site staff, (with exception of a designated pharmacist/pharmacy technician) and all study subjects will be blinded to randomized study medication assignment until database lock. Treatment assignments may be unblinded for select pre-authorized individuals involved in the safety and PK data reviews in order to accurately determine how to proceed with dose escalation.

To establish efficacy of idalopirdine as adjunctive therapy to acetylcholinesterase inhibitors (AChEIs) for symptomatic treatment of patients with mild-moderate Alzheimer's disease (AD).

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.

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.
