Active clinical trials for "Alzheimer Disease"

The trials investigates the changes of cerebral spinal fluid (CSF) soluble alpha-secretase cleaved APP (APPsα) levels under oral therapy with acitretin 30mg daily in patients with mild to moderate Alzheimer's disease (AD).The present study aims to demonstrate an enhancement of the α-secretase activity by acitretin as measured by increased CSF APPSα levels in human AD. Second, the safety and tolerability of acitretin in AD patients should be proven.

The aim of this study is to examine if combined treatment with TMS and cognitive training (CoTra) for several weeks can produce a sustained improvement in cognitive and behavioral symptomatology of mild to moderate Alzheimer's disease (AD) patients.

The purpose of this Phase I study is to determine whether the vaccine (UB 311), targeting the amyloid beta peptide (N-terminal amino acids, 1-14), is safe and immunogenic in patients diagnosed with mild or moderate Alzheimer's disease (AD). Amyloid beta was selected as the target antigen based on supporting evidence of the hypothesis that places the accumulation of amyloid beta at the initiating step of AD.

The main objectives of this proposal are as follows: To assess the dynamic uptake and washout of 123-I MNI-340, a potential imaging biomarker for β-amyloid burden in brain, using single photon emission computed tomography (SPECT) in similarly aged Alzheimer's (AD) subjects and healthy controls To perform blood metabolite characterization of 123-I MNI-340 in healthy and AD subjects to determine the metabolic fate and nature of metabolites in assessment of 123-I MNI-340 as a single photon computed tomography (SPECT) brain imaging agent

The purpose of this study is to assess the safety, tolerability, and immunogenicity of ACC-001, an investigational vaccine, in subjects with mild to moderate Alzheimer's disease in Japan.

This study was designed to assess the safety and tolerability of pioglitazone, an approved drug for type 2 diabetes, in non diabetic patients with Alzheimer's disease. It was also designed to generate preliminary information on whether pioglitazone might slow progression of Alzheimer's disease.

The present pharmacokinetic study is designed to further characterise the pharmacokinetics of the RSG XR formulation and aims to assess dose proportionality, strength equivalence, the food effect and the pharmacokinetics after repeat dosing.

The purpose of this study is to determine whether this drug can help symptoms of aggression and agitation in participants with Alzheimer's disease.

In AD, tau protein is abnormally hyperphosphorylated. Significant changes of hyperphosphorylated tau levels in CSF are found in AD patients. It has been shown in vitro that memantine can reverse abnormal hyperphosphorylation of tau in hippocampal neurons of rats. A statistically significant reduction of CSF phosphorylated tau at a preliminary 1-year follow-up was observed, from median 126 (interquartile range 107-153) to 108 (88-133) ng/l (p = 0.018). No statistically significant differences of total tau or Aβ42 were found (Gunnarsson MD, 2007). FDG-PET has the unique ability to estimate the local cerebral metabolic rate of glucose consumption, thus providing information on the distribution of neuronal death and synapse dysfunction in AD in vivo (Herholz K. 2003). Synaptic dysfunction and loss induce a reduction in neuronal energy demand that results in decreased glucose metabolism. Hypometabolism in AD is thought to reflect loss of synaptic activity and density (Herholz K. 2003; Mielke R, et al. 1998). Another biological markers such as inflammatory factor and APOEε4 also play a part in the onset of AD (Glodzik-Sobanska L, 2007).

The purpose of this study is to determine if Dimebon is safe and effective in patients with mild to moderate Alzheimer's disease on Donepezil.
