Filter by:The purpose of the study is to evaluate if AZD3480 and warfarin interact with each other or not, i.e. show the same or altered plasma concentration profiles when co-administered compared to administered alone.
The present pharmacokinetic study is designed to assess the pharmacokinetics of RSG XR as monotherapy in patients with mild Alzheimer's disease (AD) as such information will not be obtained from the current phase III trials . The study aims to enroll fourteen patients (seven of each APOE genotype). Each patient will receive a single oral dose of 4mg of RSG XR in the morning under fasted conditions and PK samples will be taken up to 36h.
The primary purpose of this study is to investigate the safety and tolerability of AZD0328 following once-daily dosing for 13 days in elderly healthy volunteers and to define maximum tolerated dose.
This is an open label, dose-ranging study of two doses of TRx0014 in patients with mild or moderate Alzheimer's Disease. The trial is made available to any patient ongoing on treatment in the clinical trial designated TRx-014-001 at termination of that study. Treatment for each individual patient will continue for as long as the treating physician feels there is benefit to the patient. This current protocol covers each patient for 12 months in the first instance.
This study will provide an initial assessment of the safety, tolerability, and pharmacokinetics (PK) of PAZ-417 after administration of ascending single oral doses to healthy young Japanese male and healthy elderly Japanese male subjects.
The aim of this project is to follow cohort of patients with aMCI in order to establish whether there are distinct subgroups in terms of evolution or aetiology, with distinct memory profiles and profiles of mesiotemporal atrophy and metabolic change
Alzheimer's disease (AD), one of the leading causes of morbidity and mortality in the elderly is characterized by progressive cognitive decline and certain neuropathological features. Currently, there is great interest in the well-documented mitochondrial (oxidative) lesion in AD. Disturbed oxidative metabolism is a well described abnormality in AD. Several observational studies have shown that moderate consumption of wine is associated with a lower incidence of Alzheimer's disease (Truelsen et al., 2002; Luchsinger et al., 2004). Wine is enriched in antioxidant compounds with potential neuroprotective activities. In the early 1990s the presence of Resveratrol in red wine was detected where it is suspected to afford antioxidant and neuroprotective properties (Miller and Rice-Evans, 1995). Blass and Gordon (2004) have demonstrated positive effects in AD with an oral preparation of glucose, malate and resveratrol. Glucose is the physiological precursor of the substrates of oxidative metabolism in the brain, malate is a primer of the energy-providing Krebs-cycle. Glucose and malate therefore can provide reducing equivalents (electrons) to regenerate the reduced form of resveratrol, and do so under the normal regulation of brain cell metabolism. All three ingredients are classified by the FDA as Generally Recognized As Safe.
This study will measure the function of a protein called P-glycoprotein (P-gp), which is found at the blood-brain barrier, a membrane that normally prevents toxic material from entering the brain. Impaired P-gp function may allow toxins to enter the brain and cause some people to develop certain brain diseases. Healthy subjects and people with Alzheimer s disease, Parkinson s disease or frontotemporal dementia who are 35 years of age or older and in overall good health may be eligible for this study. Participants undergo the following procedures during three outpatient visits to the NIH Clinical Center: - Medical history, psychological evaluation, physical examination and blood and urine tests, including tests for illegal and addictive drugs. - PET scan: This test uses small amounts of a radioactive chemical called a tracer that labels active areas of the brain so the activity can be seen with a special camera. Before starting the scan, a catheter (plastic tube) is placed in a vein in the arm to inject the tracer. The subject lies on the scanner bed, with a special mask fitted to the head and attached to the bed to help keep the head still during the scan so the images obtained are clear. A brief initial scan is done to calibrate the scanner. Then, a radioactive tracer called [(15)O]H(2)O is injected into the catheter and the PET camera takes pictures of blood flow to the brain for about 60 seconds. Next, another tracer, [(11)C]dLop, is injected into the catheter and pictures are taken for about 2 hours to determine how much of this tracer is allowed to enter the brain. - Magnetic resonance imaging (MRI): This procedure is done within 1 year (before or after) the PET scan. MRI uses a magnetic field and radio waves to produce images of the brain. For this procedure, the patient lies on a table that can slide in and out of the scanner (a tube-like device), wearing earplugs to muffle loud knocking and thumping sounds that occur during the scan.
The Connection Study is a six-month confirmatory Phase 3 study to determine the safety and efficacy of Dimebon in the treatment of mild-to-moderate Alzheimer's disease (AD).
This is a safety and tolerability study to investigate the effect of GSK239512 on mild to moderate Alzheimers disease patients. The dose of GSK239512 will be titrated to reach the most well tolerated dose in the patients.
