Filter by:Alzheimer's disease (AD) and frontotemporal dementia (FTD) are two of the most common types of age-related neurodegenerative disorders. Identifying at-risk patients and gauging disease progression in a non-invasive manner would be invaluable. Early and correct diagnosis is crucial for coordinating supportive care, patient expectations, caregiver arrangements and family planning. In addition, as treatments become available, beginning therapy early in the disease before symptoms become severe will be important. Multimodal ocular imaging (MOI) includes an ophthalmic (eye) exam and eye photographs to evaluate different layers of the retina, which is the light sensing layer of the eye. Newer technologies make it possible to visualize the disease process occurring in AD and FTD by using MOI to look at the retina, since the retina is fundamentally an outward extension of the brain itself. This study will attempt to correlate signs of disease in the retina, as determined by MOI, with plaque buildup in the brain as seen by imaging. This will demonstrate the sensitivity and specificity of MOI for diagnosing AD and FTD in a noninvasive manner.
This is a Phase-2, multicenter, multiple dose, open-label, 2-part evaluation study which will primarily assess the safety and tolerability of VTS-270 (2-hydroxypropyl beta-cyclodextrin [HP-β-CD]) in pediatric participants with age <4 years.
The Healthy Patterns Study intervention is a home-based activity intervention designed to improve symptoms of circadian rhythm disorders (CRD) and quality of life (QOL) in home-dwelling persons with dementia. We will use a randomized two-group parallel design of 200 people with dementia and their caregivers assigned to intervention or attention control groups.
A Phase 1b, Randomized, Double-Blind, Placebo-Controlled, Parallel Cohort Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Preliminary Efficacy Study of Intravenously Infused BIIB092 in Patients with Four Different Primary Tauopathy Syndromes
Early Check provides voluntary screening of newborns for a selected panel of conditions. The study has three main objectives: 1) develop and implement an approach to identify affected infants, 2) address the impact on infants and families who screen positive, and 3) evaluate the Early Check program. The Early Check screening will lead to earlier identification of newborns with rare health conditions in addition to providing important data on the implementation of this model program. Early diagnosis may result in health and development benefits for the newborns. Infants who have newborn screening in North Carolina will be eligible to participate, equating to over 120,000 eligible infants a year. Over 95% of participants are expected to screen negative. Newborns who screen positive and their parents are invited to additional research activities and services. Parents can enroll eligible newborns on the Early Check electronic Research Portal. Screening tests are conducted on residual blood from existing newborn screening dried blood spots. Confirmatory testing is provided free-of-charge for infants who screen positive, and carrier testing is provided to mothers of infants with fragile X. Affected newborns have a physical and developmental evaluation. Their parents have genetic counseling and are invited to participate in surveys and interviews. Ongoing evaluation of the program includes additional parent interviews.
A first in human phase 1 study in healthy volunteers and participants with Granulin (GRN) mutation causative of frontotemporal dementia (FTD) to assess AL001 safety, tolerability, pharmacokinetics, and pharmacodynamics
This is an open-label study to evaluate the performance of a novel tau imaging ligand in up to 36 subjects (12 AD, 3 FTD, 3 PSP, 3 CBS, 3 VCI and 12 HV). Subjects will be recruited from the patient population and healthy volunteers of Taiwan residents. This study protocol requires each subject to complete the following components: screening evaluation, brain MRI and 18F-PM-PBB3 PET imaging up to two sessions. The screening procedures will include neuropsychological assessments, vital signs, ECG, physical examinations and laboratory tests. In addition, 18F-AV-45 PET imaging result will be as a part of inclusion criteria to confirm presence of amyloid deposition in patients with clinically diagnosed probable AD or absence of amyloid deposition in FTD, VCI and HV subjects. Furthermore, 18F-AV-133 PET imaging data will also be as a part of inclusion criteria to confirm the diagnosis of PSP and CBS. All subjects will complete clinical assessments and clinical safety tests to ensure the subject is medically stable to complete the study protocol. The screening procedures will occur within 30 days prior to 18F-PMPBB3 PET imaging.
Primary progressive aphasia (PPA) is a clinical syndrome characterized by the neurodegeneration of language brain systems. Three main clinical variants are currently recorgnized (nonfluent, semantic, and logopenic PPA). Nowadays, there are no effective treatments for this disorder. Transcranial Magnetic Stimulation (TMS) is a technique based on the principle of electromagnetic induction of an electric field in the brain. It has been used as a non-invasive therapy in different disorders, such as depression, bipolar disorder, Parkinson's disease, and in the rehabilitation of post-stroke aphasia. Recent studies have shown how repetitive TMS improved language characteristics in Alzheimer's disease, and there are initial data in patients with PPA. This research project investigates the effect of repetitive TMS in patients with PPA. Investigators will perform a personalized TMS treatment for each patient (brain region, type of stimulation/inhibition, etc.), according to the specific characteristics of each patient and with the final aim to generate a computational model.
The goal of this study is to characterize tau kinetics and tau aggregation in the human CNS and to test the hypothesis that tau kinetics are altered (i.e. increased production, decreased clearance, and increased aggregation rate) in tauopathies.
The overall goal of this imaging trial is to evaluate [18F]PI-2620, a tau targeted positron emission computed tomography radioligand, in individuals with tauopathies and healthy volunteers (HV).
