Active clinical trials for "Alzheimer Disease"

The purpose of this study was to support the optimal use of rivastigmine patch in long-term treatment of Alzheimer's Disease in patients demonstrating functional and cognitive decline at the target maintenance dose of rivastigmine patch 10 cm^2.

The primary objective of the study is to investigate the effects of oral TRx0014 at three doses (30, 60 and 100 mg tid) compared with placebo on cognitive ability in patients with mild or moderate dementia of the Alzheimer type. Cognitive ability will be measured by the Alzheimer's Disease Assessment Scale - cognitive subscale (ADAS-cog). The primary evaluation will be made at 24 weeks.

We are studying subjects with mild to moderate Alzheimer's disease who have been on a stable dose of any cholinesterase inhibitor [donepezil (Aricept), rivastigmine (Exelon), or galantamine (Razadyne)] for at least 3 months, and have not previously taken memantine (Namenda). This is an open-label study, with magnetic resonance spectroscopy (MRS) as the primary outcome measure, along with neuropsychological testing, and optional lumbar puncture, evaluating patients on their stable dose of a cholinesterase inhibitor over 24 weeks, followed by another 24 weeks on memantine in combination with stable dose of cholinesterase inhibitor. The purpose of this study is to characterize the progression of disease using MRS, cerebrospinal fluid (CSF) biomarkers, and cognitive outcome measures, and to determine whether changes in cognitive function on neuropsychological testing are correlated to changes in MR spectroscopic and/or CSF biomarkers.

The purpose of this study is to find out if insulin, when administered as a "nasal spray" into the nasal passages, improves memory in adults with mild cognitive impairment (MCI) or Alzheimer's disease.

The purpose of this study is to determine whether chronic DHA (Docosahexaenoic Acid) supplementation slows the progression of cognitive and functional decline in mild to moderate Alzheimer's disease (AD).

A Double Blind, Placebo-Controlled Randomized Study to Compare the Safety and Tolerability of GTS-21 (25 Mg TID, 50 Mg TID, 75 Mg TID and 150 Mg TID) When Administered Daily for 28 Days to Participants With Probable Alzheimer's Disease

A study to investigate the safety and tolerability of both single and multiple intravenous administration of GSK933776 in patients with Alzheimer's Disease.

The purpose of this study is to test the efficacy and safety of an investigational medication for improving symptoms of Alzheimer's Disease. Subjects will receive either active medication or placebo for 28 days. Tests of memory, concentration will be included. Safety will be monitored using routine clinical and laboratory tests.

We investigate the clinical efficacy of Panax ginseng in Alzheimer's disease (AD).

To assess the safety and tolerability of ascending single oral doses of SAM-315, an investigational drug, in healthy adult subjects. To obtain a preliminary pharmacokinetic (PK) and pharmacodynamic (PD) profiles of SAM-315 in healthy subjects and to evaluate the effect of a high-fat meal on the PK of SAM-315, an investigation drug, administered to healthy adult subjects.
