View clinical trials related to Gangliosidosis, GM1.
Filter by: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.
The investigators hypothesize that a combination therapy using miglustat and the ketogenic diet for infantile and juvenile patients with gangliosidoses will create a synergy that 1) improves overall survival for patients with infantile or juvenile gangliosidoses, and 2) improves neurodevelopmental clinical outcomes of therapy, compared to data reported in previous natural history studies. The ketogenic diet is indicated for management of seizures in patients with seizure disorders. In this study, the ketogenic diet will be used to minimize or prevent gastrointestinal side-effects of miglustat. A Sandhoff disease mouse study has shown that the ketogenic diet may also improve central nervous system response to miglustat therapy (see Denny in "Citations" list below). Patients with infantile and juvenile gangliosidoses commonly suffer from seizure disorders, and use of the ketogenic diet in these patients may therefore also improve seizure management.
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.
Hematopoietic stem cell transplantation has proven effective therapy for individuals with adrenoleukodystrophy (ALD), metachromatic leukodystrophy (MLD) or globoid cell leukodystrophy (GLD, or Krabbe disease). This protocol also considers other inherited metabolic diseases such as, but not limited to, GM1 gangliosidosis, Tay Sachs disease, Sanfilippo syndrome or Sandhoff disease, I-cell disease (mucolipidosis II). For patients with advanced or rapidly progressive disease, the morbidity and mortality with transplantation is unacceptably high. Unfortunately, there are no viable alternative therapeutic options for these patients; if transplantation is not performed the patients are sent home to die. Our group at Minnesota has developed a new protocol incorporating transplantation using a reduced intensity conditioning regimen designed to decrease toxicity associated with the transplant procedure. This regimen will make use of the drug clofarabine, which has lympholytic and immune suppressive properties without the neurologic toxicity observed in the related compound, fludarabine, commonly used for transplantation. In addition, several agents providing anti-oxidant and anti-inflammatory properties will be used to assist in the stabilization of the disease processes. This revised transplant protocol will test the following: 1) the ability to achieve engraftment with the reduced intensity protocol, 2) the mortality associated with transplant by day 100, 3) patient outcomes, based on differential neurologic, neuropsychologic, imaging and biologic evaluations prior to transplantation and at designated points after transplantation (day 100, 6 months, 1, 2 and 5 years). Additional biologic studies will include pharmacokinetics of clofarabine and mycophenolate mofetil (MMF). In addition, for patients undergoing lumbar puncture studies, cerebrospinal fluid (CSF) will be requested for determinations of biologic parameters.
The purpose of this study is to determine the safety and engraftment of donor hematopoietic cells using this conditioning regimen in patients undergoing a hematopoietic (blood forming) cell transplant for an inherited metabolic storage disease.
