NCT ID: NCT01615666 Withdrawn - Clinical trials for Mild Cognitive Impairment

A Composite MR Neuroimaging Marker for Alzheimer's Disease

Start date: March 2009
Phase: N/A
Study type: Observational

The purpose of this study is to use a functional MRI (fMRI) index to compare the brain activity of healthy volunteers to that of people with mild cognitive impairment (MCI) and Alzheimer's disease. The ultimate goal is to develop an early diagnostic tool for Alzheimer's disease. The study hypotheses are: 1. The fMRI index will differentiate between Alzheimer's disease, non-Alzheimer's dementia, and healthy volunteers; 2. The fMRI index will distinguish participants with MCI who convert to Alzheimer's disease from those who convert to a non-Alzheimer's dementia and those who remain stable; 3. MCI participants with a lower fMRI index at baseline who convert will progress to Alzheimer's sooner than those with a higher fMRI index, and MCI participants with a faster rate of fMRI index decline who convert will have an earlier onset of Alzheimer's disease.

NCT ID: NCT01313806 Withdrawn - Alzheimer's Disease Clinical Trials

Study of Magnetic Fields to Treat Alzheimer's Disease

Start date: September 2011
Phase: N/A
Study type: Interventional

NCT ID: NCT01211782 Withdrawn - Alzheimer's Disease Clinical Trials

AC-1204 Long-term Efficacy Response Trial (ALERT Protocol)

ALERT
Start date: n/a
Phase: Phase 2/Phase 3
Study type: Interventional

The study will evaluate the safety & efficacy of AC-1204, a ketogenic compound, administered orally on a daily basis for 6 months. Following the 6 month double-blind phase of the study, subjects may enroll in an optional 6 month open-label extension phase. Efficacy will be evaluated by standard tests of memory and cognition, along with other measurements of activities of daily living and quality of life. Safety will be assessed by frequency of adverse events and changes in laboratory test results. Subjects will be stratified and outcomes will be separately analyzed based on apolipoprotein E4 genotype (APOE4).

NCT ID: NCT01066481 Withdrawn - Dementia Clinical Trials

A Study Of Oral PF-01913539 In Patients With Mild To Moderate Alzheimer's Disease

Start date: April 2010
Phase: Phase 2
Study type: Interventional

The purpose of this study is to demonstrate the safety and efficacy of PF-01913539 in the treatment of patients with mild-to-moderate Alzheimer's Disease. It is a 6-month study enrolling 651 patients in Japan, Hong Kong, Korea, and Republic of China. All patients completing the 6-month study will be eligible to receive PF-01913539 in an open-label extension trial (B1451031).

NCT ID: NCT00947934 Withdrawn - Memory Disorders Clinical Trials

Study of the Brain Stimulation Effect on Memory Impairment in Alzheimer Disease

Start date: August 2009
Phase: N/A
Study type: Interventional

Alzheimer's Disease (AD) is the most common cause of dementia. Today no treatment had shown consistent efficacy to stop or slow down the disease. Recent report of enhancement of memory abilities by bilateral chronic deep brain stimulation (DBS) of the fornix in the hypothalamus suggests that neuromodulation of circuits involved in memory processes may have therapeutic implications in AD patients with memory decline. The primary objectives of this prospective, non-controlled, pilot study are to assess the feasibility and safety of DBS in AD patients with mild cognitive and memory impairment, and to evaluate the efficacy of DBS to slow down or stabilize this decline. Five patients with AD (DSM IV) diagnosed less than two years, with mild cognitive decline (MMSE 20-24), and specific impairment of episodic memory will be included in a 2-year period. The evaluation criteria for feasibility will be the proportion of patients undergoing the procedure, chronic stimulation and evaluation process without adverse event (AE). Efficacy will be evaluated using numerous cognitive and memory testing including classical instrument used in AD clinical trials. Changes in behavioral scales, and changes in hypothalamic functions (clinical, biological and hormonal assessment) will evaluate safety and tolerance. Clinical, neuro-psychological, biological and imaging assessment will be performed 3 and one month before and 3, 6, 12 and 24 months after surgery. Bilateral electrodes (Medtronic 3389) will be implanted, by MR-guided frame-based stereotaxy, in the hypothalamic part of the fornix, and then connected to the generator (Kinetra, Medtronic). Chronic high-frequency stimulation will be delivered immediately after surgery. The investigators expect to slow down, or to stabilize the spontaneous decline of MMSE and ADAS scores after 6, 12 and 24 months of stimulation. In case of efficacy, DBS might offer to AD patient the possibility to slow down/stabilize their symptoms, which no other treatment can currently offer, and to increase their quality of life.

NCT ID: NCT00927108 Withdrawn - Multiple Sclerosis Clinical Trials

Rajavtihi Neuronal Adult Stem Cells Project

RNASc
Start date: July 2009
Phase: Phase 2

QTc Study of Rosi XR in Healthy Volunteers

Rosi XR
Start date: June 2009
Phase: Phase 1
Study type: Interventional

This study is a randomised double blind, parallel group, and will evaluate the effects of repeat oral doses of RSG- XR for 21 days on the QTc interval compared to placebo in a population of healthy adult males and females.

Improving Function, Quality of Life, Glycemia in Diabetics With Dementia

Phase: Phase 4
Study type: Interventional

The primary purpose of this study is to determine if the study medication Methylphenidate (Ritalin) will improve subject's blood-sugar control by improving their motivation more than placebo. The secondary objectives of the study are to determine if daily functioning and quality of life improves with methylphenidate treatment.

NCT ID: NCT00711204 Withdrawn - Clinical trials for Severe Alzheimer's Disease

Evaluating The Impact Of Donepezil Hydrochloride (Aricept) On Behavioral And Psychological Symptoms In Patients With Severe Alzheimer's Disease

Start date: January 2008
Phase: Phase 4
Study type: Interventional

A 12-week, multicenter, randomized, double-blind, placebo-controlled phase IV study. Approximately 200 subjects will be enrolled, half will receive active drug (donepezil hydrochloride) and half will receive matching placebo at approximately 50 research sites within the US, the European Union, South Africa and Australia. Eligible subjects will reside at home, in an assisted living facility, or nursing homes age and will be 50 years or older, with a diagnosis of Alzheimer's disease in the severe stage. All subjects must start with 5mg a day (one 5 mg tablet of donepezil HCL or matching placebo). Dose will be increased to 10 mg a day (two tablets of 5 mg donepezil HCL or matching placebo) after 4 weeks. Dose may be decreased based on side effects. The primary efficacy measure will be the Cornell Scale for Depression in Dementia (CSDD). Secondary measures will include Functional Assessment Staging (FAST), Mini-Mental State Examination (MMSE), NPI-10 (Neuropsychiatric Inventory), DEMQOL Proxy ( Quality of Life). Blood levels of cytokines and safety will also be assessed.
