Filter by:This was a multicenter, prospective, phase IV study evaluating safety, tolerability and effectiveness of rivastigmine 27 mg -15 cm^2 transdermal patch prescribed in patients with severe dementia of the Alzheimer's type as per discretion of treating physician.
This study is an extension of study I8D-MC-AZES (NCT02245737), the AMARANTH study. The purpose of this study is to evaluate the effectiveness of the study drug lanabecestat in participants with early Alzheimer's disease dementia at the time of entry into study I8D-MC-AZES.
Alzheimer's disease (AD) is a neurodegenerative disease leading to one of the most common forms of dementia in humans and memory disorder is one of the first symptoms that lead to diagnosis.
The aim of this study is to compare personality and social cognition changes, including emotion detection and self-awareness, and neuroanatomical correlates in patients, and how that affects the caregiver-patient relationship.
The name of this trial is MissionAD1. This phase 3 study consists of a Core and Open Label Extension (OLE) Phase in participants with Early Alzheimer's Disease (EAD), and will be conducted to evaluate the efficacy and safety of E2609. The Core is a 24-month treatment, multicenter, double blind, placebo controlled parallel group study. The OLE is a 24-month treatment, one group study. The data for the studies E2609-G000-301 (NCT02956486, MissionAD1) and E2609-G000-302 (NCT03036280, MissionAD2) will be pooled.
The investigators hypothesize that Nilotinib will be safe in individuals with mild to moderate AD. Specifically, investigators hypothesize that low daily oral doses of Nilotinib will lead to CSF penetration, CNS Abl inhibition, and stabilization of CSF total Tau and p-Tau231/181 and Abeta42/40 levels. The investigators hypothesize that Nilotinib will decrease brain load of amyloid using amyloid positron emission tomography (PET). The investigators also predict that Nilotinib will reduce CSF markers of cell death, including neuron specific enolase (NSE) and S100B.
The aim is to understand which components of attentional deployment and selection are impaired in AD during searching in realistic scenes on a computer screen (Experiment 1) and in a natural setting (Experiment 2).The investigators will also examine how deficits in visual exploration may be related to impairments in semantic, long-term memory (LTM) and working memory (WM) representations by manipulating the semantic consistency between the target and its visual surroundings, and the type of target cue (abstract vs. precise), respectively. Perceptual saliency of target and distractor objects will be also manipulated in Expt.1, In Expt.2, in order to determine how deficits in visual exploration may be involved in the IADL deficits shown by AD patients, participants at each trial will be required to search in a natural settings different types of targets and then to perform an IADL using five objects, among which one of the searched targets. Measures analysed: for the search tasks (Expt. 1 and 2): eye movements in different search phases, accuracy and response times; for IADLs tasks (Expt. 2): eye movements during action planning and execution, motor efficiency (number and types of action performed), time to terminate the activity. Compared to controls, the investigators expect that AD patients will have reduced ability using scene semantic LTM in order to locate the objects, greater attentional capture from highly salient features and greater search performance impairment when higher WM resources are required (abstract target cues). The investigators also expect that their performance at IADLs will be less efficient and, in particular, less organized than control, with reduced advantage of eye guidance.
This is an open-label study to evaluate Aftobetin-HCl and florescence detection as measured by the Sapphire II device. Performance of Part I of the study has been completed (15 subjects received a single administration of Aftobetin HCL followed by Sapphire II measurements) and indicated that 3 administrations of Aftobetin-HCl are necessary. For Part II, a second group of up to 30 subjects (CN =10 and mild AD or MCI =20) will receive three Aftobetin HCL administrations. If three administrations of Aftobetin HCL are optimal, up to an additional 30 MCI and 30 mild AD subjects will be entered. The purpose of the study as Part II is performed is to determine the ability of the Sapphire II device to detect B-amyloid in the lens of the eye in subjects with Mild Cognitive Impairment (MCI), and mild Alzheimer's Disease (AD) after three Aftobetin-HCl administrations. Subjects with Normal Cognition (CN) will also be tested to further establish that subjects who are highly unlikely to have B-amyloid deposits in the lens of the eye will have close to baseline post ligand fluorescent uptake value (FUV) using the Sapphire II technology.
This study evaluates the safety and pharmacological effects of 3 different doses of Posiphen® when compared to a placebo, in adult male and female patients with early Alzheimer's disease (AD).
By doing this study, researchers hope to learn if older adults with and without cognitive impairment can adhere to a Mediterranean diet.
