Active clinical trials for "Fragile X Syndrome"

This trial will evaluate the efficacy and safety of ZYN002, a clear cannabidiol gel that can be applied to the skin (called transdermal application) twice a day for the treatment of behavioral symptoms of Fragile X Syndrome (FXS). Eligible participants will then participate in up to a 14 week treatment period, where all participants will receive placebo or active study drug. Patients ages 3 to < 18 years, will be eligible to participate.

To evaluate safety and tolerability of epigallocatechin gallate (EGCG) in children from 6 to 12 years old with Intellectual Developmental Disorders (IDD) (Down syndrome or Fragile X syndrome).

The purpose of this study is to determine whether Lovastatin, Minocycline and the combination Lovastatin/Minocycline are effective in treating behavioral symptoms in Fragile X individuals.

This study will evaluate the safety, tolerability and efficacy of multiple doses of AFQ056 in patients with Fragile X Syndrome. The dose range will be 50 to 150 mg b.i.d. The primary read-out of efficacy is reduction in Aberrant-Behavior Checklist score.

Fragile X syndrome is the most common known inherited cause of neurodevelopmental disability. Functional magnetic resonance imaging (fMRI) studies from our laboratory indicate that specific brain regions using the neurochemical, acetylcholine, show significantly reduced activation during learning. Since donepezil is a medication that enhances acetylcholine function in the brain, the purpose of this study is to determine if donepezil has any beneficial effect on behavior or cognition in subjects with fragile X syndrome.

The purpose of this study is to determine vitamin C and vitamin E in combination are effective in the treatment of cognitive and behavior disorder in children with fragile X syndrome.

Fragile X Syndrome (FXS) is caused by loss of FMR1 expression on the X chromosome that leads to increased mRNA translation, which results in hyperactivation of ERK (extracellular signal-regulated kinase) and mTORC1 (mechanistic target of rifampicin complex 1) signalling and consequently in synaptic dysfunction and neurological development. There is presently no cure for FXS. Recent studies suggest that metformin (a widely prescribed drug for type II diabetes in children and adults) which crosses the blood-brain barrier, corrects various neurological and behavioral FXS phenotypes by normalizing ERK signaling, EIF4E phosphorylation and lowering expression of MMP9 to normal. Since this drug has not been previously used specifically for treatment of FXS (only few cases reported), the investigators propose an open-label trial of metformin in children and adults with FXS to better understand the safety and efficacy in both behavior and cognition.

This Phase IIb study is designed to assess whether 3 doses of AFQ056 are safe and effective in treating the behavioral symptoms of Fragile X Syndrome.

This study is a control trial of sertraline (Zoloft) in fragile X syndrome children aged 2 years to 5 years 8 months old. The trial is six months long, and each participant will receive a series of tests at both the beginning and end of the study. The researchers hope to show improvements in language and a decrease in autistic symptoms.
