Filter by: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.
The purpose of the study is to test the efficacy of a 20 week multi-modal treatment comprised of lovastatin or placebo, and the Parent-implemented Language Intervention (PILI) in children with fragile X syndrome (FXS). Children will be randomized to drug or placebo in a double-blind design with all participating in the PILI. The primary endpoint will be to measure improvements in spoken language and behavior among lovastatin-treated than placebo treated participants.
The purpose of the study is to evaluate a 2-3 day treatment probe targeted to improving social gaze behavior in children with fragile X syndrome (FXS). The investigators will use the principles of Applied Behavior Analysis (ABA) to shape appropriate social skills. Importantly, the investigators propose to examine the effects of this treatment probe on brain and behavior.
The purpose of this study is to examine the safety and efficacy of Allopregnanolone as a possible treatment for symptoms of Fragile X-associated Tremor/Ataxia Syndrome (FXTAS).
The Decisional Capacity and Informed Consent in Fragile X Syndrome (FXS) project is for the Eunice Kennedy Shriver National Institute of Child Health & Human Development, 1R01HD071987-01A1, and will provide the first comprehensive description of decisional capacity of individuals with FXS; identify individual, family, and experiential factors associated with variability in decisional capacity; determine the validity of caregiver and expert ratings; and develop evidence-based guidelines for categorizing decisional capacity of individuals with FXS. The researchers will develop a methodologically rigorous and conceptually grounded decision aid using digital technology to enhance participation of individuals with FXS in the consent process.
This study is a multisite, randomized, double-blind, placebo-controlled, phase 2 study of MG01CI (low dose and high dose once daily) for 6 weeks compared with placebo in a 1:1 ratio of 60 adolescent and adult subjects with Fragile X Syndrome (FXS). Following Screening, subjects will be randomized to MG01CI or matching placebo at Baseline (Day 0) and the 6 week Double-blind Treatment Period will begin on Day 1. The first 4 weeks of the treatment period will be a dose-optimization period, All subjects will start with two daily tablets: low dose metadoxine or matching blinded placebo. At weekly visits/phone assessments, the investigator will evaluate the dose based upon the investigator's assessment of safety and tolerability. If the subject demonstrates safety or tolerability concerns with the low dose after 1 or 2 weeks of treatment, then the subject will be discontinued. If there are no concerns about safety and tolerability after 2 weeks of treatment, then the dose will be increased to high dose or placebo. If at the high dose there are concerns about safety and tolerability, then the dose will be either kept the same or reduced to low dose for the remainder of the treatment period. There will be a 2-week Follow-up Period after the last dose of study treatment or early termination.
In this research study we want to understand the effectiveness of a drug treatment, acamprosate, for interfering symptoms (i.e., inattention/hyperactivity, social impairment) associated with Fragile X Syndrome (FXS).
The purpose of this study is to determine whether NNZ-2566 is safe and well tolerated in the treatment of Fragile X Syndrome in adolescent and adult males.
Fragile X syndrome (FXS) presents alterations in synaptic plasticity that produce intellectual disability. can produce improvement. Estrogens (targeting Estrogen Receptors beta (ER-β) can act as neuroprotective agents, promoting synaptic plasticity and neurite outgrowth, and health benefits derived from flavonoids, as the flavonol epigallocatechin gallate (EGCG), phytoestrogens of natural origin are partially explained by their interaction with membrane ER. Selective ER-β flavonoids are thus good candidates for their therapeutic evaluation in intellectual disabilities. EGCG also targets central intracellular transduction signals altered in FXS and improves memory recognition in a FXS animal model(adenosine triphosphate (ATP)-inhibitor of phosphatidylinositol 3-kinase (PI3K)and mammalian target of rapamycin (mTOR) and extracellular signal-regulated kinase (ERK1/2). This study targets the synaptic plasticity alterations that underlie the learning and memory impairment but also the computational disability in FXS. The hypothesis is that EGCG can act by favoring the physiological processes involved in cognition.
This randomized, double-blind, placebo-controlled, parallel-arm study will evaluate the safety and exploratory efficacy and pharmacokinetics of RO4917523 in pediatric patients with fragile X syndrome. Patients will be randomized to receive one of 2 dose levels of RO4917523 or placebo orally daily for 12 weeks.
