Filter by:A preliminary assessment of the safety, tolerability and efficacy of Ergoloid mesylates (EM) and 5-hydroxytryptophan (5-HTP) and the combination (EM + 5-HTP) compared to placebo in males aged 18-45 years old with Fragile X Syndrome.
This is a randomized, double-blind, placebo-controlled, multiple-center study, to assess the efficacy and safety of Cannabidiol administered as ZYN002 for the treatment of children, adolescent, and young adult patients with Fragile X Syndrome (FXS). Eligible participants will participate in up to an 18-week treatment period, where all participants will receive placebo or active study drug. Patients ages 3 to < 23 years will be eligible to participate.
The purpose of this study is to accumulate and quantitatively analyze data on the microbiome, serotonin signaling and genetics, and inflammatory cytokines from patients with Autism Spectrum Disorder and Fragile X Syndrome. Computational analysis of multi-dimensional datasets will be used to establish a "Diagnostic and Therapeutic Index" - an objective set of tools that can help differentiate subtypes of Autism Spectrum Disorder and develop more accurate methods of diagnosis and response to treatment.
This study is to investigate the safety, tolerability and efficacy of Sulindac (HLX-0201) and Gaboxadol (HLX-0206) in males with Fragile X Syndrome (FXS) with confirmed full FMR1 mutation treated over a 10 week period in an outpatient setting.
The purprose of this study is to develop and validate an analytical NIPD test for triplet repeat disesases by NGS analysis from maternal blood, searching for the familial mutation in families at risk of having one of the following triplet repeat diseases: Huntington's disease, Myotonic dystrophy, Fragile X syndrome.. A comparison of two 3rd generation long fragment DNA sequencing techniques will be performed. These methods are based of the phasing techniques of parental haplotypes without the proband.
Fragile X Syndrome (FXS) and Williams-Beuren Syndrome (WBS) are relatively rare disorders characterized by developmental delay associated to socio-communicative deficit and autistic-like behaviours. WBS has been considered for a long time as the "polar opposite" of ASD, given their hypersociable phenotype. Nonetheless, recent researches have emphasized similarities between ASD and WBS phenotypes. By following some authors "social abnormalities in ASD and WS can be characterized in terms of analogous difficulties in social cognition), and distinct patterns of social motivation which appears to be reduced in ASD and enhanced in WBS". More than opposite condition, these authors suggests that WBS and ASD could share the same difficult in comprehension of social relationship, with opposite pattern of social engagement (enhanced in WBS and weakened ASD). Given, these similarities authors suggest testing the feasibility and validity of therapy for ASD in children with WBS. Parent Mediated Therapy (PMT) is a group of "technique-focused interventions where the parent is the agent of change and the child is the direct beneficiary of treatment". PMT demonstrated evidence of effectiveness in socio-communicational improvement for children with ASD in a randomized controlled trial (RCT). Some recent researchers have extended the use of PMT to children with genetic disorders and autistic features, such as FXS. While showing encouraging results, the samples of research were limited. They main aim of this research is to to verify effectiveness of Cooperative PMT (CMPT) for socio-communicative deficit in children with FXS and WBS. Our hypothesis is that CPMT, in addition to conventional rehabilitation therapies (mainly speech therapy and occupational therapies), could contribute to the enhancement of socio-communicative skills and the reduction of behavioural problems. We also expected also an improvement in family quality of life and a reduction of parental stress.
Fragile X syndrome (FXS) is the most common genetic cause of autism spectrum disorder (ASD). The investigators wish to examine brain distribution of sigma-1 receptors in young adult males with FXS using 18F-FTC-146 PET. This project will study the distribution of sigma-1 receptors in 15 young (18-30 years) male adults with FXS compared to 5 healthy adult volunteers.
The investigators wish to compare the brain distribution of GABA(A) receptors and GABA levels in young adult males with Fragile X Syndrome compared to idiopathic intellectual developmental disorder. The radiopharmaceutical [18F]flumazenil has been used to study GABA(A) receptor distribution in other genetic syndromes with autistic features; however, despite overwhelming evidence supporting the importance of the GABAergic system in FXS, no clinical investigation of this system in human FXS has been reported in the literature. Therefore, this study will provide the first in vivo comprehensive examination of the GABAergic system in FXS using hybrid positron emission tomography/ magnetic resonance imaging (PET/MRI).
The purpose of this trial is to investigate the use of metformin in the treatment of Fragile X syndrome (FXS) patients. Metformin is an FDA approved compound with an established safety profile and minimal side effects that specifically targets and normalizes multiple aspects of the pathophysiology in FXS. This is a randomized double-blind placebo-controlled 2-arm parallel group design study of the drug metformin and placebo in FXS subjects with a primary outcome measure of safety/tolerability and secondary outcome measures on cognition, attention, anxiety, sleep, and physiologic and biochemical biomarkers.
This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records regarding autism.
