NCT06338267
The VIBRANT study aims to validate biosensors to objectively and directly measure symptoms in Rett syndrome and create confidence in the use of these devices in clinical trials. VIBRANT will use several FDA-cleared wearable biosensors and a non-wearable device to collect symptom data from patients with Rett syndrome for up to 9 weeks. Symptoms of interest include heart rate, breathing, sleep, blood oxygen levels, and movement. Participants will use the biosensors intermittently at home, document device use and symptom status, and will come to the clinic for 1 overnight sleep study. A cohort of up to 10 participants receiving an intervention in a separate clinical trial may also enroll and participate on a custom device schedule for up to 1 year. The study will provide information on the feasibility and ease of use for families at home, biosensor data will be compared to data collected at the same time from the overnight sleep study to demonstrate how well they work in individuals with Rett syndrome, and Emerald will be developed to include movement as a measurable symptom.

The REVEAL Pediatric Study is a multi-center, Phase 1/2 open-label, dose-escalation and dose-expansion study of TSHA-102, an investigational gene therapy, in pediatric females with Rett Syndrome. The safety, tolerability, and preliminary efficacy of two dose levels will be evaluated. The study duration is up to 6 years.
NCT07150013
The RETT REVOLUTION trial is a placebo-controlled, single-blinded, exploratory study with patients serving as their own control ("N of 1" trial design) where the safety and efficacy of vorinostat in the treatment of Rett syndrome will be evaluated. Each patient will be self-controlled in an adapted N-of-1 study design methodology by using a 4-week placebo baseline. Vorinostat dose escalation will occur every 8 weeks of daily dosing: placebo, 80mg/m2/day, 160mg/m2/day. Key study objectives will include: * To confirm the safety and tolerability of oral vorinostat 80mg/m2/day and 160mg/ m2/day dose levels when administered to typical Rett patients * To identify the nature and magnitude of treatment response to vorinostat, as measured by changes in clinical and laboratory parameters indicative of trend towards benefit, as well as changes in mRNA expression (transcriptome response) * Provide a data-driven justification for future study design and statistical analysis plan for subsequent clinical studies assessing safety and efficacy of vorinostat in Rett syndrome
NCT06856759
Rett syndrome (RTT) is a serious neurodevelopmental disorder that has a significant impact on patients and their families. Patients suffer from severe social dysfunction and poor quality of life, and there is currently no effective treatment available. The MECP2 functional loss mutation is the clear pathogenic factor. In recent years, gene therapy has been applied in neuromuscular diseases such as SMA and has achieved good safety and effectiveness. Professor Qiu Zilong's self-developed AAV-MECP2 gene therapy product for RTT was found to significantly improve disease symptoms in RTT model mice, and demonstrated good safety in heath injection testing in monkeys. The dose exploration study of AAV-MECP2 initiated by our researchers is a multicenter, single arm, single intrathecal injection. The plan is to explore two target doses, with 5 subjects enrolled in dose 1 and 3 subjects enrolled in dose 2, to evaluate the safety, tolerability, and preliminary efficacy of single intrathecal injection of AAV-MECP2 in the treatment of RTT.
NCT06621043
This 18-week open-label study examines the effectiveness of Full-Spectrum Medicinal Cannabis Plant Extract containing 0.08% THC (NTI164) in treating Rett syndrome (RTT) in children and young people. The study aims to determine the impact of NTI164 on RTT symptoms over a 16-week treatment period. Participants will start with a daily dose of 5 mg/kg of NTI164, which will be gradually increased over four weeks until they reach either the maximum tolerated dose or 20 mg/kg per day. They will then maintain this dose for eight weeks. Following this treatment phase, the dosage will be reduced by 5 mg/kg each week for four weeks until treatment concludes. The effectiveness of the treatment will be assessed using tailored questionnaires that measure changes in the patients\' conditions. Additionally, full blood examinations will be conducted at multiple points throughout the study to monitor the effects of the treatment.

NCT04463316
Introduction Rare complex syndromes Patients with complex genetic syndromes, by definition, have combined medical problems affecting multiple organ systems, and intellectual disability is often part of the syndrome. During childhood, patients with rare genetic syndromes receive multidisciplinary and specialized medical care; they usually receive medical care from 3-4 medical specialists. Increased life expectancy Although many genetic syndromes used to cause premature death, improvement of medical care has improved life expectancy. More and more patients are now reaching adult age, and the complexity of the syndrome persists into adulthood. However, until recently, multidisciplinary care was not available for adults with rare genetic syndromes. Ideally, active and well-coordinated health management is provided to prevent, detect, and treat comorbidities that are part of the syndrome. However, after transition from pediatric to adult medical care, patients and their parents often report fragmented poor quality care instead of adequate and integrated health management. Therefore, pediatricians express the urgent need for adequate, multidisciplinary adult follow up of their pediatric patients with rare genetic syndromes. Medical guidelines for adults not exist and the literature on health problems in these adults is scarce. Although there is a clear explanation for the absence of adult guidelines (i.e. the fact that in the past patients with rare genetic syndromes often died before reaching adult age), there is an urgent need for an overview of medical issues at adult age, for 'best practice' and, if possible, for medical guidelines. The aim of this study is to get an overview of medical needs of adults with rare genetic syndromes, including: 1. comorbidities 2. medical and their impact on quality of life 3. medication use 4. the need for adaption of medication dose according to each syndrome Methods and Results This is a retrospective file study. Analysis will be performed using SPSS version 23 and R version 3.6.0.
NCT05691582
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: 1. Grail environment (training in dark conditions, interaction with wide and surrounding screen, positioning over the treadmill); 2. time to prepare a set of body marker in order to execute a gait analysis; 3. walking activity over treadmill, with immersive virtual reality; 4. proprioceptive stimulatione provided by the GRAIL platform; 5. 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

Randomized, placebo-controlled trial of oral calcium supplementation for osteopenia in girls and women with Rett syndrome
NCT04920110
This measurement validation study will use qualitative and quantitative methodology to evaluate the Observer-Reported Communication Ability Measure (ORCA), to appropriately capture communication abilities in individuals with Rett syndrome. The ORCA Measure is a caregiver-reported questionnaire that collects caregiver observations of their child's communication abilities including expressive, receptive and pragmatic communication types. Caregivers will participate via phone interviews and online surveys. Approximately 270 participants will be enrolled.
NCT03941444
ANAVEX2-73-RS-002 is a Phase 3, double-blind, randomized, placebo-controlled dose escalation safety, tolerability and efficacy study in patients 18 years and older with RTT using endpoints including multiple clinical and exploratory molecular and biochemical measures.
NCT02738281
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).
NCT03196323
The overall purpose of this study is to develop a broad-based (i.e., multiple domains) behavioral outcome measure for children between the ages of 3-18 years with Rett syndrome (RTT). The innovative approach of this proposal consists of integrating the process of developing a behavioral questionnaire to an ongoing large-scale data collection project. The Natural History Study of Rett Syndrome and Related Disorders (RTT5211) is a project that collects data on diverse aspects of the clinical evolution of individuals with RTT and related disorders. This project will serve as the basis for recruitment of subjects and it will also provide key demographic and clinical data for cohort characterization and for determining clinical relevance of the instrument (RettBe). An initial 100-subject cohort will allow for the testing with one rater of RettBe 1.0, a 50-item questionnaire formed from existing measures, a panel of clinicians and behavioral experts in RTT, and a focus group of parents and caregivers of children with RTT. Scores on RettBe 1.0 will be statistically analyzed to determine their psychometric properties, including its content validity. Items that do not meet psychometric standards (e.g., ceiling effect) will be eliminated. Additional items will be added if the parental survey attached to RettBe 1.0 or clinician input suggests so. The resulting modified assessment, called RettBe 2.0, will be administered to a larger (validation) cohort of 300 participants. RettBe 2.0 will also be subjected to analysis of psychometric properties. RettBe 2.0 will also be administered to two raters per subject, in order to determine inter-rater reliability. In addition, these raters will be completing other behavioral and clinical measures for further evaluating the validity of RettBe 2.0 as well as for determining its clinical and functional significance. Finally, the investigators will obtain input from a panel of clinicians (site PIs and their designated clinicians) about content validity and clinical impact. The resulting version will be released as RettBe 3.0.
NCT04167059

This is a phase 2 , open label, dose escalating study of Lovastatin in Rett syndrome.
NCT01520363
Dr. Sakkubai Naidu, Principal Investigator, is initiating a double blinded placebo controlled clinical drug trial using dextromethorphan (DM) in Rett Syndrome (RTT), at the Pediatric Clinical Research Unit (PCRU) of the Johns Hopkins Hospital/Kennedy Krieger Institute. Funding source , FDA-00PD It has been shown that receptors for a certain brain chemical called glutamate, in particular the NMDA type, are increased in the brain of young RTT patients (\<10 years of age). This chemical and its receptors, when in excess, cause harmful over-stimulation of nerve cells in the brain, contributing in part to the seizures, behavioral problems, and learning disabilities in RTT. The investigators propose to initiate a specific treatment using DM to counter/block the effects of this brain chemical and its excessive receptors to improve the ill effects of increased glutamate/NMDA receptors, because of DM's identified ability to block NMDA receptors. DM is available for human consumption. Infants and children with respiratory infections and cough, as well as non-ketotic hyperglycinemia, are treated with DM, which has been well tolerated.
NCT01777542
Investigators are recruiting children for a clinical trial using the medication recombinant human IGF-1 (a.k.a. mecasermin or INCRELEX) to see if it improves the health of children with Rett syndrome (RTT). While IGF-1 is approved by the Food \& Drug Administration (FDA) for certain use in children, it is considered an investigational drug in this trial because it has not previously been used to treat RTT. Information from this study will help determine if IGF-1 effectively treats RTT but will not necessarily lead to FDA approval of IGF-1 as a treatment for RTT.
