Active clinical trials for "Tauopathies"

This is a non-interventional observational study designed to systematically record the results of routine laryngeal examinations and specific characteristics of dysphagia in patients with multiple system atrophy (MSA), Parkinson's disease (PD) and progressive supranuclear palsy (PSP) and related 4repeat tauopathies. The results of a fiberoptic / flexible endoscopic evaluation of swallowing (FEES) while performing a structured task protocol will be recorded. If available, laryngeal electromyography (EMG) results will also be recorded. In addition to the examination results, demographic and disease-specific data are collected, and two questionnaires, the Swallowing Disturbance Questionnaire for Parkinson's Disease (SDQ-PD) and the swallowing specific Quality Of Life Questionnaire (SWALQOL), are administered.

Alzheimer's disease (AD) is the most common cause of dementia and currently has no disease modifying treatments or simple accurate diagnostic tests. The goal of this project is to study how tau (a protein thought to cause AD) is made, transported and cleared in the human body. Better understanding of these processes may lead to improved understanding of AD, earlier diagnosis and a way to evaluate treatment.

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

This is a randomized, double-blind, placebo controlled, single ascending dose escalation, safety, tolerability, PK, PD and immunogenicity study of BMS-986168 administered by an intravenous infusion in healthy subjects.

The purpose of this study is to determine the safety and tolerability [maximum tolerated dose (MTD) within planned dosing range] of intravenous (IV) infusions of TPI 287 administered once every 3 weeks for 9 weeks (for a total of 4 infusions) in patients with primary four repeat tauopathies (4RT), corticobasal syndrome (CBS; also called corticobasal degeneration, CBD) or progressive supranuclear palsy (PSP).

The primary objective of the study is to obtain preliminary safety and tolerability data with davunetide (NAP, AL-108) in patients with a tauopathy (frontotemporal lobar degeneration [FTLD] with predicted tau pathology, corticobasal degeneration syndrome [CBS] or progressive supranuclear palsy [PSP]). The secondary objectives of this study are to obtain preliminary data on short term changes (at 12 weeks) in a variety of clinical, functional and biomarker measurements from baseline, including cerebrospinal fluid (CSF) tau levels, eye movements, and brain MRI measurements.

This study is a multicenter, double blind, randomized, placebo-controlled study to evaluate the safety, tolerability and immunogenicity of different doses, regimens and combinations of Tau targeted vaccines in participants with early Alzheimer's Disease.

The goal of this Phase 2 MCI study is to determine whether 1.0 mg/kg XPro1595 is superior to placebo at improving measures of cognition, functioning and brain quality in individuals with MCI and biomarkers associated with neuroinflammation (APOE4) and to evaluate safety, tolerability, and efficacy of XPro1595.

This is a bridging study to visually and quantitatively assess PET images obtained after single application of 300 MBq [18F]florbetaben and PET scanning of patients with Alzheimer disease.

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.
