Active clinical trials for "Alzheimer Disease"

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

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.

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.

The study will include a preliminary pharmacokinetics (PK) / safety / tolerability evaluation in healthy elderly subjects followed by the Receptor Occupancy (RO) evaluations in healthy elderly subjects and in Alzheimer's Disease (AD) subjects.

This is a randomized, double-blind, placebo- and moxifloxacin (open-label)-controlled, 4-period crossover study.

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

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

The purpose of this study is to demonstrate that AZD3480 improves cognition in patients with mild or moderate Alzheimer's disease, to assess the safety and tolerability of ZAD3480 and to define the optimal dose(s) to be used in future trials.

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).
