Filter by:The clinical project "Eight At One Stroke: Attention Gangliosidoses" represents a clinical registry for recording the clinical manifestation and the disease progression of gangliosidoses. The intention of this project is to better understand the manifestation and progression of gangliosidoses and to raise awareness of these disorders in the public health service. The patients or their families, respectively, will be integrated in the study in order to measure Patient Outcome and to objectify the psychosocial burden for the patient and his family. The study has a retrospective and a prospective part. It is planned to transfer the data of the study into a continuous registry.
To evaluate the efficacy and safety of GM1 for preventing cognitive impairment related to whole brain radiotherapy in breast cancer patients with brain metastases. And explore the clinical and molecular parameter for predicting severe cognitive impairment induced by WBRT and gaining benefit from GM1. Primary Endpoint: the change of Hopkins Verbal and Learning Test-Revised Delayed Recall,HVLT-R DR,before and after WBRT Secondary ENDPOINT: the change of Alzheimer's Disease Assessment Scale-Cognitive，ADAS-Cog before and after WBRT;severe cognitive impairment percentage and onset time; Design:204 patients will be randomly assigned to exp.group,102 cases,and 102 cases of control group.
Owing to the rarity, severity, speed of progression and fatal prognosis of infantile and juvenile GM1, there is a limited understanding of overall disease progression and meaningful outcome measures. This study aims to build a natural history data set through collection of a number of clinical, imaging, and laboratory assessments that may be specific predictors of GM1 disease progression and clinical outcome. Having a GM1 natural history data set can inform potential efficacy endpoints and biomarkers for future clinical trials. This natural history study will follow up to 40 subjects diagnosed with GM1 gangliosidosis (up to 20 infantile (Type 1) and 20 late infantile/juvenile (Type 2)) for up to 3 years. Visits will be conducted every 6 months, during which several procedures will be performed and the data recorded in order to learn about the natural course of the disease, including changes in clinical and neurological assessments and electrophysiologic, imaging and biofluid biomarkers. Study procedures include: physical & neurological exam, blood & urine sample collection, questionnaires & assessments of development, seizure diary, ECHO, ECG, x-ray and ultrasound (if MRI not performed), EEG and genetic testing (if not already done). The following procedures are subject to local/institutional policies and the medical discretion of the Study Physician: MRI, lumbar puncture (spinal tap) and General anesthesia/sedation (for MRI and LP).
Background: GM1 gangliosidosis is a disorder that destroys nerve cells. It is fatal. There is no treatment. People with GM1 are deficient in a certain enzyme. A gene therapy may help the body make this enzyme. This could improve GM1 symptoms. Objective: To test if a gene therapy helps Type I and Type II GM1 gangliosidosis symptoms. Eligibility: Type I subjects will be male and female >= 6 months <= 12 months of age at the time of full ICF signing. Type II subjects will be male and female > 12 months old and < 12 years old at the time of full ICF signing. Design: Participants will be screened with their medical history and a phone survey. Participants will stay at NIH for 8-10 weeks. Participants will have baseline tests: Blood, urine, and heart tests Hearing tests Ultrasound of abdomen EEG: Sticky patches on the participant s head will measure brain function. Lumbar puncture: A needle will be stuck into the participant s spine to remove fluid. MRI scans, bone x-rays, and bone scans: Participants will lie in a machine that takes pictures of the body IQ tests Neurology exams Central line placement Skin biopsy: A small piece of the participant s skin will be removed. Speech tests Participants will have an x-ray while swallowing food. Participants will take drugs by mouth and IV. This will get their immune system ready for therapy. Participants will get the gene therapy by IV. They may stay at NIH for a week to watch for side effects. Participants will have visits 3 and 6 months after treatment. Then visits will be every 6 months for 2 years. Then they will have a visit at 3 years. Visits will take 4-5 days. Participants will return to NIH once a year for 2 years for tests in an extension study....
The purpose of this study is to understand the course of rare genetic disorders that affect the brain. This data is being analyzed to gain a better understanding of the progression of the rare neurodegenerative disorders and the effects of interventions.
Hypothesis: To characterize and describe disease progression and heterogeneity of the gangliosidosis diseases. This research study seeks to develop a quantitative method to delineate disease progression for the gangliosidosis diseases (Tay-Sachs disease, Sandhoff disease, and GM1 gangliosidosis) in order to better understand the natural history and heterogeneity of these diseases. Such a quantitative method will also be essential for evaluating any treatments that may become available in the future, such as gene therapy. The data from this study will be necessary to provide end-points for future therapies, guide medical decisions about treatment, provide objective measurement of treatment outcomes, and accurately inform parents regarding potential outcomes.
