Filter by:The primary objective of the study is to evaluate whether a set of algorithms analysing acoustic and linguistic patterns of speech, can predict change in PACC5 between baseline and +12 month follow up across all four Arms, as measured by the coefficient of individual agreement (CIA) between the change in PACC5 and the corresponding regression model, trained on baseline speech data to predict it. Secondary objectives include (1) evaluating whether similar algorithms can predict change in PACC5 between baseline and +12 month follow up in the cognitively normal (CN) and MCI populations separately; (2) evaluating whether similar algorithms trained to regress against PACC5 scores at baseline, still regress significantly against PACC5 scores at +12 month follow-up, as measured by the coefficient of individual agreement (CIA) between the PACC5 composite at +12 months and the regression model, trained on baseline speech data to predict PACC5 scores at baseline; (3) evaluating whether similar algorithms can classify converters vs non-converters in the cognitively normal Arms (Arm 3 + 4), and fast vs slow decliners in the MCI Arms (Arm 1 + 2), as measured by the AUC, sensitivity, specificity and Cohen's kappa of the corresponding binary classifiers. Secondary objectives include the objectives above, but using time points of +24 months and +36 months; and finally to evaluate whether the model performance for the objectives and outcomes above improved if the model has access to speech data at 1 week, 1 month, and 3 month timepoints.
This study is being conducted to test the safety, tolerability, and pharmacokinetics of the investigational drug CY6463 compared with placebo in individuals who are aged 60 years or older and have Alzheimer's disease (AD) along with common cardiovascular risk factors.
The purpose of this platform study is to evaluate the effect of anti-inflammatory agents on cognition in early Alzheimer's disease. Additionally, the safety and tolerability of these anti-inflammatory agents and the effects on central and peripheral inflammation will be evaluated.
ASN51-101 is a randomized, double-blind, placebo-controlled, phase 1 first in human (FIH) safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) study of oral ASN51 in healthy young adult and elderly subjects and elderly subjects with AD. The study is comprised of three parts (Part 1, Part 2, and Part 3).
The purpose of this study is to evaluate the safety, tolerability, and preliminary efficacy of SNK01 (autologous natural killer cell), as a single agent, for the treatment of subjects with Alzheimer's disease.
This is a Phase II, multicenter, open-label, single arm, PD study in participants with early (prodromal to mild) AD to evaluate the effect of a once weekly (Q1W) dosing regimen of gantenerumab on deposited amyloid as measured by change from baseline to Week 104 (primary) and Week 208 in brain amyloid positron emission tomography (PET). The administration of gantenerumab as a single injection of Q1W will be investigated in this study, to simplify the dosing regimen for participants.
The purpose of this study is to measure the amount of amyloid in the brain. Amyloid is a protein found in the brain of patients with Alzheimer's disease and can be detected using a Positron Emission Tomography (PET) scan. This study is interested in how amyloid levels in the brain relate to memory and thinking abilities.
The purpose of this research study is to learn whether it is possible and useful for caregivers to report behavioral or psychological symptoms of people with mild memory problems or Alzheimer's disease through a smartphone mobile application. The investigators believe that monitoring these symptoms and having a tool, like a mobile application, can provide quicker accessibility to the patient's clinical care team, which could improve care for patients and caregivers. These types of symptoms found in patients with mild memory problems or Alzheimer's disease are any type of psychiatric symptoms or abnormal behaviors one might develop as the result of these brain illnesses. Examples of psychological and behavioral symptoms are depression, anxiety, insomnia, irritability, agitation, and hallucinations. These symptoms differ from regular psychiatric symptoms, because they are caused by mild memory problems or Alzheimer's disease (AD). These symptoms can cause a lot of distress for patients and caregivers, and can lead to greater use of healthcare services.
This is an open-label, multicenter, rollover study to evaluate the safety, tolerability, and efficacy of long-term administration of open-label gantenerumab in participants with AD who completed Study WN29922 or WN39658, either the double-blind or open-label extension (OLE) part.
The main purpose of the study was to evaluate the safety and tolerability of long-term administration of gantenerumab in participants with AD. All participants who have completed the open-label extensions (OLEs) of studies WN25203 or WN28745 were enrolled in Part 1 of this study. Of these, participants who completed Week 104 visit in Part 1. Participants received open-label gantenerumab by subcutaneous (SC) injection every four weeks (Q4W) at the same dose as administered in the parent studies (part 1)/ Week 104 visit.
