Filter by:The aim of this study is to measure the effect of EGb 761® versus placebo on the ratio of the isoform of the protein precursor of beta amyloid platelets, in patients with mild to moderate Alzheimer's disease.
This is a Phase III, multicenter, open-label extension, single-group study in male and female outpatients with mild-to-moderate Alzheimer's disease (AD) who have completed either AVA102670 or AVA102672. All subjects will receive rosiglitazone extended-release (RSG XR) 4mg once daily for the first 4 weeks of the study followed by 8mg RSG XR as adjunctive therapy to their existing dose of acetylcholinesterase inhibitor. Subject participation will last until one of 5 conditions applies. After a 52-week open-label treatment phase, subjects will attend a final Follow-Up Visit 6 weeks after the end of treatment. The primary objective of this study is to evaluate the long-term safety and tolerability of RSG XR in subjects with mild-to-moderate AD who have completed either AVA102670 or AVA102672. The secondary objective of this study is to explore further the long-term efficacy of RSG XR in terms of cognitive function and overall clinical response as a function of apolipoprotein E (APOE) e4 allele status.
Primary: To assess the safety and tolerability of ascending multiple oral doses of SAM-315, an investigational drug, in healthy young adult and elderly subjects. Secondary: To assess the Pharmacokinetic and Pharmacodynamic profiles of multiple oral doses of SAM-315 in healthy young adult and elderly subjects.
The purpose of this protocol is to measure a receptor in the brain using positron emission tomography (PET) that is involved in inflammation.
Open-label treatment with MPC-7869 for participants in a previous randomized study.
The purpose of this study is to determine whether standard medications approved for Alzheimer's disease treatment differ in their action on brain functioning and whether any observed brain activity differences as result of treatment are associated with particular patterns of dementia improvement or reduced decline.
MK0952 is a phosphodiesterase type IV (PDE4) inhibitor in development for improvement of cognitive impairment in mild-to-moderate Alzheimer's disease.
Clinical features in patients with the familial early onset forms and the sporadic forms of Alzheimers disease are similar, although the course of deterioration may be different. It would be very informative to examine the drug response of patients with Alzheimers disease by a certain genotype to find evidence favouring genotype-specific drug responses that may indicate genetically defined phenotypic differences in alzheimers disease.
This is a multinational, randomized, double blind, placebo controlled, parallel group study comparing the safety and efficacy of daily dosing of 800 mg twice daily MPC-7869 to placebo. Study subjects will have the diagnosis of mild dementia of the Alzheimer's type. Subjects may be taking approved medication for Alzheimer's disease provided the dose has been stable for at least 6 months.
The overall goal of this double-blind Phase II study is to evaluate the safety, efficacy and biological mechanisms of action of Intravenous Immunoglobulin (IVIg) in the treatment of mild to moderate stage Alzheimer's disease (AD). IVIg contains antibodies against the amyloid beta protein that is the central component of the AD senile plaque. It is hypothesized that IVIg treatment will reduce the levels of beta amyloid in the brain and improve cognitive abilities relative to placebo. A total of 24 patients with mild to moderate AD capable of giving informed consent will be randomly assigned to receive either IVIg (16 patients)or saline placebo (8 patients) for six months. This study includes comparison of four dosing regimens of IVIg. Cognitive, behavioral and functional measures will be collected at baseline, three months and six months of treatment. Plasma samples will be collected before and after infusions. Subjects will undergo a lumbar puncture before and after the six months of treatment for cerebrospinal fluid (CSF) biomarker analyses. In addition, Positron Emission Tomography (PET) imaging substudies will be performed at two time points during the study. Following the initial 6 month placebo-controlled period, all participants have the opportunity to receive IVIg for an additional 12 month period in an extension study.
