Filter by:In each of the 7 French areas that should be involved, patients aged 75 years and over from three different sectors will be included: the geriatric consultation unit (60%) and two kinds of nursing homes, private (20%) and state (10%). Outpatients will be included in chronological order; patients in nursing homes will be included at random. The patients and their families will be asked about the treatments received on the day of inclusion. The inclusion period will extend over a year. The investigating practitioners will be asked to fill in a questionnaire reporting the main clinical data, adverse effects occurrence, and information on the treatment given.
This study will estimate the radiochemical and radiation safety and assess the efficacy of [18F]MK-3328, a novel positron emission tomography (PET) tracer. The study safety hypotheses will test whether [18F]MK-3328 is sufficiently safe and well-tolerated, based on an assessment of clinical and laboratory evaluations and adverse experiences in healthy participants, including healthy elderly (HE) participants, and Alzheimer's disease (AD) participants, to permit continued investigation. The study efficacy hypothesis will test whether [18F]MK-3328 can discriminate between AD participants and cognitively normal elderly control participants based on tracer volume of distribution, or one of its surrogates, in brain posterior cingulate gyrus.
PHASE: Phase 0, Exploratory Study OBJECTIVES: To collect drug safety, bio-distribution and dosimetry data, to begin collection of PET/CT imaging data, to acquire experience to improve study design and the conduct of future studies. DESIGN: Exploratory, open label, non-randomized, multi-center study. DURATION: Three visits - one screening, one imaging, and one follow-up visit at 24 hours post-dose PROCEDURES: Informed consent, collection of demographic information and medical history, administration of mental status exam, physical examination, vital signs, 12-lead ECGs, routine blood tests to assess major organ functions, complete blood counts and clinical chemistries for safety, dosing with [F-18]W372, PET imaging scans of brain (in sixteen subjects), whole body PET imaging and urine collections for dosimetry evaluation (in four subjects only), observation and interviews following imaging to collect adverse events. SUBJECTS: Twenty (20) subjects ≥ 55 years old: Group 1 will consist of 10 subjects who have a low probability of being currently positive for Alzheimer's Disease (AD) as defined by the protocol criteria (MMSE ≥ 28). Four of the 10 subjects will undergo whole body PET imaging for dosimetry evaluations, and 6 of the 10 subjects will undergo PET imaging of the brain only. Group 2 will consist of 10 subjects who have a high probability of currently being positive for AD as defined by the protocol criteria (MMSE < 24); these 10 subjects will undergo PET imaging of the brain only.
The purpose of this study is to evaluate the safety and tolerability of single oral doses of CHF 5074 in young healthy male volunteers.
EGCG has shown a neuroprotective effect in cell-experimental and animal studies. The neuroprotective mechanism of EGCG probably bases - besides the known antioxidant effect - amongst others on the modulation of several signal transduction pathways, the influence on the expression of genes which regulate cell survival resp. programmed cell death, as well as the modulation of the mitochondrial function. In different Alzheimer models EGCG seems to cause an induction of alpha-secretase and the endothelin-converting-enzyme, as well as to prevent the aggregation of beta-amyloid to toxic oligomers through the direct binding to the unfolded peptide. The investigators therefore expect EGCG to have a positive influence on the course of the Alzheimer´s Disease.
Capturing the earliest stages of Dementia especially Alzheimer's Disease (AD) is a great challenge. Until now the NINCDS-ADRDA and the DSM criteria for AD were largely used as diagnostic standards in research. However, the research on AD progresses and some biomarkers have been recently suggested to improve the diagnostic criteria of AD, such as cerebrospinal fluid markers, neuroimaging with Positon Emission Tomography (PET) or Magnetic Resonance Imaging (MRI).
This is a efficacy and safety study evaluating new treatment for subjects with mild to moderate Alzheimer's Disease.
The core study assessed the efficacy of a higher dose of rivastigmine 13.3 mg/24 h transdermally (15 cm^2 patch) compared to a lower dose of the rivastigmine 4.6 mg/24 h transdermally (5 cm^2 patch) in patients with Severe Dementia of the Alzheimer's Type in a 24-week study. The extension study obtained additional safety and efficacy data, as well as provided the higher dose rivastigmine patch to all patients who completed the core study for an additional 24 weeks.
The purpose of this study is to evaluate if 4 escalating doses during 20 weeks of NP031112 are safe and tolerated in patients with Alzheimer´s disease.
The aim of this study is to demonstrate the efficacy of timed exposure to bright light for the treatment of disturbed nighttime sleep and daytime wake in community-dwelling dementia patients and their caregivers, and to determine if there are genetic relationships between memory problems and sleep problems
