Active clinical trials for "Supranuclear Palsy, Progressive"

Progressive Supranuclear Palsy and related disorders (PRD) are debilitating, costly, and understudied conditions. Improving access to comprehensive, specialized, in-home patient care offers the potential to minimize the downward spiral of morbidity and preventable healthcare utilization. The aim of this study is to test whether and to what degree an interdisciplinary home visit program will improve patient- and caregiver-reported outcomes, and to identify unmet needs in this population.

This protocol is designed to assess the utility of a new positron emission tomography (PET) radiopharmaceutical to image tau, [18F] JNJ067, invented by Janssen Pharmaceutical companies of Johnson & Johnson. To date, the radiopharmaceutical has been used in a small group of patients and controls (<20). The study plans to expand the range and number of subjects, to examine a total of 18 participants including controls and patients with Alzheimer's disease (AD) and other dementias. All patients will be recruited from the University of California, San Francisco (UCSF) Memory and Aging Center (MAC) and controls will be recruited from the University of California, Berkeley Aging Cohort Study (BACS). Patients will undergo a multidisciplinary clinical evaluation for diagnosis and a cognitive assessment at the MAC; controls will undergo the usual BACS cognitive assessment performed on the Berkeley campus. Following these evaluations UCSF subjects will undergo magnetic resonance imaging (MRI) scanning at the UCSF Neuroimaging Center and blood sampling for genetic testing also at UCSF, and BACS subjects will undergo an MRI at the University of California Berkeley 3T Brain Imaging Center (in Li Ka Shing hall on the Berkeley campus) and blood sampling for genetic testing at the time of the PET scan. All subjects will come to Lawrence Berkeley National Law (LBNL) where they will have, on the same day, a C-11 Pittsburgh compound B (PIB) PET scan to measure brain amyloid, and an F-18 JNJ067 PET scan to measure brain tau. These scans will be examined and analyzed by LBNL staff, and data will be processed to examine basic questions about the quantitative behavior of JNJ067. Scan results will not be returned to control subjects, but physicians at UCSF will receive scan results on MAC patients and will share results with participants. As part of this protocol, the investigators also plan to share the acquired data widely. All data will be de-identified. Data will be shared with the inventors (Janssen/Johnson & Johnson) as well as other scientists worldwide. As this is a new radio tracer, the investigators anticipate that there will be interest in seeing the actual data to answer questions about uptake and application of the method in future studies in many different laboratories. Shared data will include PET scans, MRI scans, genetic testing, and neuropsychological results.

Treatment of tauopathies such as Progressive Supranuclear Palsy (PSP) and Cortico Basal Degeneration (CBD) remains a major challenge. These rare severe neurodegenerative extrapyramidal movement disorders share phenotypic overlap and are usually painful. Parkinson disease (PD) is a common extrapyramidal movement disorder and continuous subcutaneous apomorphine infusion (CSAI) is commonly used in advanced PD patients to alleviate motor and non-motor fluctuations. Effects of subcutaneous apomorphine were investigated especially on pain and, on quality of life in 7 patients with PSD or CBD.This is an observational "real life" surveillance-based study.The Verbal Rating Scale for Pain (VRS) was used to assess changes in pain level and the clinical global impression-improvement scale (CGI-I) was used to assess changes in patient's illness before and during six months of treatment. Detailed report of the symptoms and side effects has been recorded by home nurses throughout the study period.

The main hypothesis is that the gait and postural deficits in the Caribbean form of PSP may be associated with a dysfunction of the cerebral cortex, as they result from sub-cortical involvement in classical forms. The investigators will characterize the gait and posture with a force platform to collect biomechanical gait parameters, coupled with the kinematic and electromyographic (EMG) study. Then the investigators realize a multimodal imaging study [structural magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI)] that allow us to determine if a correlation can be found between the clinical characteristics of postural control and walking on one hand, and morphological changes and structural MRI changes in cortico-subcortical pathways on the other hand. The study of performance on neuropsychological tests, registration of ocular movements and the analysis of functional cortical activity will complete our multimodal approach. A better understanding of these disorders is expected to propose new drug treatment and rehabilitative strategies.

The aim of the project is to develop the first alpha-synuclein (a-syn)-specific PET tracer. The research phase will exploit ACI's proprietary MorphomerTM library and extensively optimized screening workflow. Promising PET-tracer candidates will be tested for their ability in detecting a-syn pathology in patients with a range of Parkinsonian conditions with different a-syn levels and distributions, comprising hereditary forms of PD and other synucleinopathies.

This is an experimental medicine study to evaluate the kinetics of cerebrospinal fluid (CSF) biomarkers in subjects with Alzheimer's disease (AD) or progressive supranuclear palsy (PSP) compared to healthy controls using a heavy water (2H2O) labeling method. This study is exploring the time profile of appearance and disappearance of pulse deuterium-labeled cargo proteins in CSF of subjects with AD and/or PSP, which is different from healthy controls, due to deficits in fast axonal transport.

Drug therapy of atypical parkinsonism is generally considered either ineffective or minimal 1. Therefore, there is an urgent need to find alternative therapies to treat atypical parkinsonian disorders. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive tool that modulates cortical excitability with minimal discomfort and holds therapeutic promise in treating neurological and psychiatric disorders. The basal ganglia-thalamocortical circuits that are affected in Progressive Supranuclear Palsy (PSP) and Corticocbasal Ganglionic Degeneration (CBGD) are likely structurally and functionally segregated. The 'motor' circuit is implicated in parkinsonian akinesia and hypokinesia; a 'prefrontal' circuit is implicated in working memory and mood regulation, and linked with non-motor symptoms such as depression and apathy. In this proposal, we characterize motor and prefrontal network dysfunction in PSP and CBGD patients, and propose that high-frequency and low-frequency rTMS directed over separate motor and prefrontal cortical targets of each network may show specific and selective beneficial effects on motor vs. cognitive function in PSP and CBGD patients, respectively. Quantitative motor outcome measures include timed finger tapping tasks. Quantitative cognitive outcome measures comprise a visual analogue scale (VAS). If successful, this pilot study will provide proof of principle data to suggest potential benefits for rTMS in PSP/CBGD patients, and provide sufficient data and experience to support future PSP/CBGD studies that include the use of rTMS to investigate the pathophysiology of motor and non-motor features of PSP and CBGD patients.

The overall goal of this imaging trial is to characterize [18F]MNI-815, a PET radioligand for imaging Tau.

The overall goal of this imaging trial is to evaluate [18F]MNI-958, a tau targeted PET radioligand, in individuals with Alzheimer's disease (AD), Progressive Supranuclear Palsy (PSP), and healthy volunteers (HV).

The goal of this study is to assess [18F]MNI-777 PET imaging as a tool to detect tau pathology in the brain of individuals who carry a clinical diagnosis of a tauopathy, including: Alzheimer's Disease (AD),Parkinson's disease (PD) Progressive Supranuclear Palsy (PSP), chronic traumatic encephalopathy (CTE) and Frontal Temporal Dementia (FTD) and age- and gender-matched healthy subjects.
