Filter by:The primary objective of this study is to characterize cerebral metabolism modifications using 18F-FDG PET technology and perfusion with 99MTC-ECD SPECT in patients with prodromal Alzheimer's Disease drawn from a high risk population. We also compare PET and SPECT imaging within this framework, and search for optimal diagnostic thresholds.
The purpose of this study will be to evaluate the safety and tolerability of lecanemab at sequentially ascending doses in subjects with mild to moderate Alzheimer's disease (AD).
This study in individuals with early Alzheimer's disease is designed to assess:(1) safety and tolerability (2) the capacity of ACC-001 and QS-21 adjuvant to reduce brain amyloid load as measured by positron emission tomography (PET) scans.
This is a Phase 1 study in healthy subjects to evaluate the safety and tolerability of LY2886721 multiple doses, how the body handles the drug, and the drug's effect on the body.
Patients who were vaccinated with AFFITOPE AD01 during AFFiRiS001 will undergo a long-term follow-up period to get more information regarding the safety profile of AFFITOPE AD01.
This multi-center, randomized, double-blind, placebo-controlled parallel-group study will evaluate the effect of gantenerumab (RO4909832) on cognition and functioning and the safety and pharmacokinetics in participants with prodromal Alzheimer's Disease. Participants will be randomized to receive subcutaneous (SC) injections of either gantenerumab or placebo. Participants who consent to be part of the sub study will undergo positron emission tomography (PET) scanning to assess brain amyloid. The anticipated time on study treatment is 104 weeks in Part 1, with an option for an additional up to 2 years of treatment in Part 2, followed by an open-label extension (Part 3) until July 2020. The dosing for Parts 1 and 2 was stopped after a planned futility interim analysis showed a low probability of meeting the primary outcome measure with the doses studied. The study has converted to open-label to investigate higher gantenerumab doses.
The overall goal of this project is to establish and validate biomarkers associated with the risk and progression of late onset Alzheimer's disease, mild cognitive impairment and cognitive decline. The investigators will use baseline and longitudinal measurements of plasma amyloid beta-40 and amyloid beta-42 to investigate the risk of developing mild cognitive impairment and late onset Alzheimer's disease, as well as the rates of cognitive decline and Alzheimer's disease progression. The driving hypothesis of the study is that amyloid beta in the brain as measured by positron emission tomography positivity is associated with the onset of cognitive decline associated with late onset Alzheimer's disease.
This study is designed as a single ascending dose study in healthy subjects to evaluate safety, tolerability, Pharmacokinetics (PK), and Pharmacodynamics (PD) in plasma and Cerebrospinal (CSF) following single oral doses of E2212.
Dementia is a serious health problem showing an increasing prevalence rate with increasing age. In Norway, about 80% of nursing home patients have dementia. The mean age of nursing home residents in Norway is around 84 years. Disruptive and agitated behaviour affect 30-50% of all individuals with dementia at some point in the course of the illness. In addition, they have a combination of physical and psychological diseases which necessitates a close collaboration between different specialities in medicine and Old Age psychiatry. In collaboration with the communalities, our Old Age psychiatry services want to provide a new approach to this challenge and validate it on patient and personnel level.
This research will look at how the brain may change in people with Alzheimer disease (AD). The purpose of this research is to find out whether changes in the brain in people with Alzheimer disease can be detected using a brain imaging test. Most people with Alzheimer disease have changes in the brain that result in deposits of a protein called beta-amyloid. In this study, the investigators will be using a radioactive drug, [18F]MNI-558 that binds to beta-amyloid. This drug is experimental and has not been approved by the FDA. Brain imaging using PET (positron emission tomography) will be done to see if the investigators can evaluate the areas of beta-amyloid in the subjects with Alzheimer disease. The investigators will compare these scans with those done in healthy normal volunteers. PET is a brain-scanning test used in medicine and scientific research to see how the brain is working. The PET imaging test used in this study is not being done for diagnostic purposes.
