View clinical trials related to Rett Syndrome.
Filter by:Rett syndrome (RTT) is a genetic encephalopathy and the typical form is caused by mutations in the gene MECP2. It is a genetically heterogeneous pathology. CDKL5 and FOXG1 have been recently discovered being involved in other forms of RTT. However, at least 5% of typical forms and more other atypical forms are not linked to any of 3 genes known to be involved in the disease. The purpose of this study is to identify new genes involved in molecular etiology of typical and atypical forms of RTT.
The purpose of this study is to advance understanding of the natural history of Rett syndrome (RTT), MECP2-duplication disorder (MECP2 Dup), CDKL5, FOXG1, and individuals with MECP2 mutations who do not have RTT including the range of clinical involvement and to correlate genotype-phenotype over a broad spectrum of phenotypes. While much has been learned about RTT, improvements are required in understanding the role of factors such as X chromosome inactivation, genetic background, and others including the environment, on the great variability observed even between individuals with the same MECP2 mutation. These data will be essential to the development and conduct of clinical trials that are anticipated from ongoing studies in animal models for RTT. This study will not include clinical trials, but should set the stage for such trials and other translational research projects (e.g., development of biomarkers).
The purpose of this study is to determine whether NNZ-2566 is safe and well tolerated in the treatment of Rett syndrome in children and adolescents.
The overarching purpose of this study is to advance understanding of the natural history of Rett syndrome (RTT), MECP2-duplication disorder (MECP2 Dup), RTT-related disorders including CDKL5, FOXG1, and individuals with MECP2 mutations who do not have RTT. Although all these disorders are the result of specific genetic changes, there remains broad clinical variation that is not entirely accounted for by known biological factors. Additionally, clinical investigators currently do not have any biomarkers of disease status, clinical severity, or responsiveness to therapeutic intervention. To address these issues, biological materials (DNA, RNA, plasma, cell lines) will be collected from affected individuals and in some cases from unaffected family members, initial evaluation performed to identify additional biological factors contributing to disease severity, and these materials will be stored for future characterization.
This study will investigate sleep behavior in subjects with Angelman Syndrome, Rett Syndrome or Prader-Willi Syndrome. The study will also investigate sleep behavior in healthy siblings of subjects with Angelman Syndrome, Rett Syndrome or Prader-Willi Syndrome. These individuals will serve as control subjects. The study will use questionnaires designed to identify sleep disorders and how they affect behavior and quality of life. The principal goals of this study are: 1. To see how common sleep disorders are in individuals with Angelman Syndrome, Rett Syndrome or Prader-Willi Syndrome; 2. To see how sleep disorders affect behavior in these individuals; 3. To see whether sleep disorders and related behavior problems improve or worsen with age; 4. To see how specific disease conditions relate to sleep disorders and how bad the sleep disorders are; 5. To develop new treatment options to improve quality of life and behavior issues; and 6. To evaluate current treatment options to improve sleep problems in these individuals.
This is a phase 2 , open label, dose escalating study of Lovastatin in Rett syndrome.
Children with neuromuscular disabilities and limited ambulation are at significant risk for decreased bone mineral density (BMD) and increased incidence of fracture. This is caused, in part, by low levels of load experienced by the skeleton due to a child's functional limitations. Low BMD has been shown to be predictive of fracture, and in fact, fractures usually occur without significant trauma in children with neuromuscular conditions. The discomfort and distress from fractures in this population are considerable, and the associated costs to the family and healthcare system are substantial. Numerous interventions have been devoted to improving BMD in these children. Stationary assisted standing devices are widely used and represent the standard-of-care. However, evidence supporting this approach is limited due to inadequate study designs with insufficient numbers of patients. This study will use load-sensing platforms in patients with neuromuscular conditions. Successful completion of this pilot study will assist in the development of a future multicenter clinical trial to definitively determine relationships, if any, between passive standing and measures of BMD, fracture incidence, pulmonary function, and health-related quality-of-life measures in children with a variety of neuromuscular disabilities (e.g., spinal muscular atrophy, cerebral palsy, muscular dystrophy, spina bifida, Rett syndrome). Hypothesis: Assisted standing treatment program will gradually increase their duration of standing by up to 75% after the baseline phase.
A phase 2 open label trial to test a potential drug treatment for Rett syndrome, the leading known genetic cause of severe neurological impairment in girls. The drug, Copaxone (generic name - Glatiramer acetate) is medication FDA approved for the treatment of multiple sclerosis. Copaxone's high safety profile has been documented in large cohorts of patients for more than 12 years.
Based on our clinical observations, many girls with RETT syndrome, a severe neuro-developmental encephalopathy, suffer from osteoporosis which can appear at a very early age (before age 10) and can lead to fractures, pain and a limitation in mobility. Few epidemiological studies have estimated the frequency of osteoporosis in girls with RETT syndrome and showed that they are more exposed then children with other neuro-developmental diseases with a same degree of neurological handicap. However, the mechanisms that lead to early osteoporosis in RETT syndrome remain unknown. Mutations in the MECP2 gene are found in 95% of RETT patients and preliminary experimental studies have shown that this can lead to abnormal expression of the gene that codes for osteoprotegerin, a protein implicated in bone remodelling by interacting with RANK-ligand. In order to identify risk factors of osteoporosis in RETT syndrome and to understand the pathophysiological mechanisms the study protocol includes: 1. Clinical evaluation of bone health (history of bone fractures, pain, nutritional status, pubertal stage, daily caloric/calcium intake, anti-epileptic drugs, walking ability, vitamin D satus) 2. evaluation of the mineral density at the lumber spine using DEXA 3. measuring concentrations of osteoprotegerin and RANK-ligand
The Trial Objective is to assess safety and efficacy of oral fingolimod (FTY720) in children older than 6 years with Rett Syndrome. So far there is no established treatment for children with Rett Syndrome. Therefore a positive result in terms of safety and first indications of efficacy would path the way to a phase II clinical study with more patients to further test the hypothesis that fingolimod treatment may slow down the regression of motor and language skills.
