Active clinical trials for "Rett Syndrome"

The goal of this observational study is to identify candidate biomarkers in individuals with Rett Syndrome (RTT). The main questions it aims to answer are: Do these biomarkers change during clinical changes in individuals with RTT? Are biomarkers stable over time in clinically stable individuals? Do these biomarkers correlate with severity of RTT? Participants will be asked to undergo an electroencephalogram (EEG) with measurements of Evoked Potentials (EP) to measure electrical activity in the brain. Researchers will compare findings in individuals with RTT to those in typically developing individuals to see if there are differences between the two groups.

The main goal of this study is to investigate the tolerability to the use of the GRAIL system in subjects affected by Rett syndrome, particularly referred to: Grail environment (training in dark conditions, interaction with wide and surrounding screen, positioning over the treadmill); time to prepare a set of body marker in order to execute a gait analysis; walking activity over treadmill, with immersive virtual reality; proprioceptive stimulatione provided by the GRAIL platform; cognitive-attentive span time to the activity proposed. The secondary goal is to understand if a training that avail of treadmill and virtual reality would be useful in the future in improving gait characteristics in subjects affected by Rett syndrome

The aim of the study is to evaluate the feasibility and health-related effects of an individualized 12wk 'uptime' participation intervention in girls and women with Rett syndrome. Girls and women above 5 years of age with Rett syndrome and a confirmed MECP2 mutation will be included. Each individual program focuses on participation in enjoyable activities to promote 'uptime' in home, school/day center and community settings. Primary outcomes are sedentary time and daily steps. Secondary outcomes are gross motor skills, walking capacity, quality of life and participation-level goals. Outcomes are evaluated on four occasions: at baseline and after a 6-week interval, immediately following the 12-week intervention program and 12 weeks after the intervention program.

Creatine supplementation in RTT: a randomized controlled trial Rett Syndrome (RTT) is a neurodevelopmental disorder characterised by apparently normal early development (stage 1 of RTT) followed by loss of purposeful hand use, distinctive hand stereotypes, slow brain growth, loss of language, respiratory irregularities, gastrointestinal disturbances, gait abnormalities, seizures, and mental retardation. These symptoms typically appear between 6 and 18 months of age (stage 2). Subsequently, there is gradual stabilisation of severe mental retardation and motor compromise (stage 3). The majority (70% to 80%) of patients show mutations in the methyl-CpG-binding-protein-2 (MeCP2) gene, located on chromosome Xq28. MeCP2 encodes a transcription repressor protein that is ubiquitously expressed in all tissues. As RTT primarily affects females, only very few males with mutations in MeCP2 have been identified. Mutations in MeCP2 have also been identified in children with X-linked mental retardation, autism and a clinical phenotype that resembles Angelman Syndrome. The aim of this study is to investigate the effects of a dietary supplement on the biochemical and clinical parameter of RTT. About 80 % of labile methyl groups generated through the re-methylation cycle are used for the synthesis of creatine within the human organism. Supplementation of creatine will therefore increase the availability of labile methyl groups for different methylation reactions including methylation of DNA. The study will be double blind and cross-over. The patients will get creatine monophosphate (200 mg/kg/d in three dosages per day) or placebo. After 6 months and a wash-out period of 4 weeks the groups are changed for the next 6 months. All participants with RTT and mutations in MeCP2 will undergo physical and neurological exam, quantitative EEG, behavioral assessment, laboratory testing, and neuropsychological evaluations. Participants will have a follow-up after 3, 6, 10, 13 and 16 months (3 months after finishing the study), which will include similar assessments.

This study will recruit families with a daughter with Rett syndrome living in either Australia, Denmark or Israel, and thereafter deliver individually designed participation programs using telehealth strategies. We will evaluate the effectiveness of the programs on reducing sedentary behaviours, increasing physical activity and increasing quality of life.

Primary Objective: To test the hypothesis that 6 months treatment with glatiramer acetate (GA) decreases epileptiform activity in young girls with Rett syndrome. Primary Safety Objective:To evaluate the safety and tolerability of 6 months treatment with GA in these patients. Secondary Objectives: To test the hypothesis that 6 months treatment with glatiramer acetate (GA) improves respiratory dysfunction. To evaluate the effect of GA treatment on general behaviour communication, hand stereotyping, feeding, sleep and other autonomic symptoms: gastrointestinal and cardiac. To assess the effect of GA treatment on bodily development. Primary Endpoint:Improvement of epileptiform activity as recorded in a 24-hours EEG. Primary Safety Endpoint:Frequency and severity of treatment-related AEs (including safety lab parameters). Secondary Endpoints: Improvement in the scoring of breath holds and hyperventilation, as measured with non-invasive respiratory inductance plethysmography (NoxT3 device) and parents' diaries. Changes in general behaviour, communication, feeding and motor skills as assessed by the investigator (based on Kerr and Naidu validated severity scores) and recorded in parents' diary. Decrease in seizure frequency as reported in parents' diary. Improvement in sleep schedule as recorded in a sleep diary. Change in height and weight. Population:Ten girls, 6 to 15 years old, diagnosed with Rett syndrome (RTT) Study Design:This is a single - center, exploratory, open-label, study in 10 girls diagnosed with RTT. The study will consist of four parts: Screening and baseline assessments, initial and final dose-setting period, treatment period and end-of study follow-up. Investigational Product:Glatiramer Acetate (Copaxone® , Teva Pharmaceutical Industries Ltd.) Sample Size Consideration: The planned sample size of 10 patients was considered adequate by the investigator for this phase I exploratory proof-of-concept study. The study is not expected to show statistical significance or statistical power, only a trend for the study endpoints. Each patient will serve as her own control. Duration of Study: Approximately 8 months per patient (including up to 2 weeks pre-treatment assessment, 6 months initial dose and treatment periods and end-of study visit). Overall study duration: the study is expected to be completed within 12 months (dependent on rate of recruitment).

This study will examine the potential efficacy and safety of Rett-T for core motor deficits of Rett syndrome, and will explore biological markers of safety and treatment response.

This is a single-center, exploratory, open-label study in 10 girls diagnosed with Rett Syndrome. The study will consist of the following 4 parts: Screening/Baseline run-in, Titration/Dose-Setting, Treatment, and Washout/Follow-up.

Rett syndrome (RTT) is a disorder in which the nervous system does not develop properly. RTT generally affects girls, but there are some boys who have been diagnosed with RTT. Symptoms of RTT include small brain size, poor language skills, repetitive hand movements, and seizures. This study will evaluate the effectiveness of two drugs in treating the symptoms of RTT.

Pediatric movement disorders comprise of a large number of different neurological diseases including Rett syndrome (RTT) and Tourette syndrome. Studies in the literature as well as our preliminary reports showed that Rett syndrome and Tourette syndrome/Tic disorders are associated with a dysbiosis of the gut microbiota compared to normal control. Probiotic Lactobacillus plantarum PS128 is a diet supplement that available for human consumption. Probiotic Lactobacillus plantarum PS128 had showed psychotropic effects such as ameliorate anxiety- and depression-like behaviors as well as altered the level of neurotransmitters such as dopamine in the brain in animal models, which might be through microbiota-gut-brain axis. Therefore, the purpose of this study is to access the possible neurobehavior effects of Probiotic Lactobacillus plantarum PS128 in Rett syndrome and Tic disorders/Tourette syndrome.
