Active clinical trials for "Alzheimer Disease"

The purpose of this study is to determine whether scopolamine-induced cognitive impairment is attenuated by the administration of roflumilast in combination with donepezil.

Part 1 is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy and safety of gantenerumab in participants with mild Alzheimer disease. Participants will be randomized to receive either gantenerumab subcutaneously every 4 weeks or placebo subcutaneously every 4 weeks. Approved Alzheimer medication is allowed if on stable dose for 3 months prior to screening. Part 2 is an open-label extension (OLE). A positron emission tomography (PET) imaging substudy will be conducted within the main study. Eligible participants who provide separate informed consent will undergo PET imaging scans using the radioligand florbetapir as a pharmacodynamic measure of changes in brain amyloid load over time.

To evaluate the long-term safety and tolerability of idalopirdine (Lu AE58054) as adjunctive therapy to donepezil in patients with mild-moderate Alzheimer's Disease (AD).

This combined phase 1/2a clinical trial is to investigate the safety, dose limiting toxicity (DLT), and exploratory efficacy of three repeated intraventricular administrations of NEUROSTEM® (human umbilical cord blood-derived mesenchymal stem cells) versus placebo via an Ommaya reservoir at 4 week intervals in patients with Alzheimer's disease.

Alzheimer's Dementia (AD) is a major public health problem. Apathy, a profound loss of motivation, is seen in majority of patients with AD. Dysfunction of the front of the brain and loss of dopamine, a type of neurochemical, in this part of brain results in apathy. Presence of apathy is linked to deficits in planning sequential tasks such as keeping a routine. Patients with apathy have poor physical function and their caregivers experience extra burden. Unfortunately there are no good medications to treat apathy. FDA has approved the use of brain stimulation by a magnet known as repetitive transcranial magnetic stimulation (rTMS), for treatment of depression. rTMS increases dopamine when applied to frontal lobe of brain so we propose that rTMS would be a good treatment option for apathy in AD. Study hypotheses include that rTMS to the dorsolateral prefrontal cortex (DLPFC) will improve apathy and executive function better than sham treatment in those with AD.

The population of dementia is increasing rapidly. Cognitive impairment as well as Behavioral and psychological symptoms of dementia (BPSD) add heavy burdens to caregiver. NMDA activation is critical for learning and memory. Individuals with Alzheimer's disease (AD) have fewer NMDA receptors in the frontal cortex and hippocampus than controls. This study is a randomized, double-blind, placebo-controlled drug trial. All patients will be allocated randomly to two groups: (1) NMDA enhancer: DAOIB (starting dosage: 250-500 mg/day), (2) placebo, for 6 weeks. The investigators hypothesize that DAOIB may yield better efficacy than placebo for cognitive function and clinical symptoms in patients with BPSD.

The purpose of the study is to evaluate safety and the pharmacodynamic effects of BMS-241027 on cerebrospinal fluid (CSF) Tau, connectivity magnetic resonance imaging (MRI), and computerized cognitive tests in mild Alzheimer's disease (AD) subjects, following 9 weekly intravenous (IV) infusions of BMS-241027

This study is designed as a single ascending dose study in healthy subjects to evaluate safety, tolerability, Pharmacokinetics (PK), and Pharmacodynamics (PD) in plasma and Cerebrospinal (CSF) following single oral doses of E2212.

This study examined the effects of modafinil on apathetic symptomatology, performance of activities of daily living (ADLs) and caregiver burden in individuals with Alzheimer's disease (AD).

The purpose of this study will be to evaluate the safety and tolerability of lecanemab at sequentially ascending doses in subjects with mild to moderate Alzheimer's disease (AD).
