Active clinical trials for "Fragile X Syndrome"

This study will investigate the safety, tolerability and blood pharmacodynamics of treatment with oral administration of AZD7325 at 5 mg BID, 15 mg BID, and placebo BID, in adults with Fragile X Syndrome. The study also will also investigate measures of efficacy and biomarkers during treatment.

The purpose of this study is to determine the effectiveness and tolerability of aripiprazole in the treatment of children and adolescents with Fragile X Syndrome.

This study will investigate whether CX516 can improve attention, memory, language, or behavior in adults with Fragile X Syndrome and/or Autism. CX516 is an AMPAKINE® compound. AMPAKINE compounds enhance synaptic strength. There is evidence to suggest that the synapses in the brain of an individual with fragile X syndrome are immature and abnormal. It is possible CX516 may partially correct this synaptic transmission defect and lead to improvement in cognitive and behavioral functioning. There is also reason to believe that these changes caused by CX516 could be helpful in managing cognitive and behavioral symptoms in patients with autistic disorder. Involvement for each participant will last 28 days. Participants will be given study medication, a physical exam, and a variety of cognitive assessment tests to study potential drug effectiveness at improving disease symptoms.

This is a single-center, randomized, double-blind, 2-period crossover study to explore the effects of BPN14770 on cognitive function and behavior in subjects with Fragile X Syndrome. Subjects will receive both active treatment with BPN14770 capsules and matching placebo capsules in the course of the study. One treatment will be administered during each of the 12-week study periods.

The purpose of this study is to assess the safety, tolerability and efficacy of oral OV101 (gaboxadol) in subjects with Fragile X syndrome.

The trial is a Phase 1 Single Dose PK Study in Adolescent Subjects with Fragile X syndrome (FXS) or Angelman syndrome (AS). The primary objective of the study is to evaluate the pharmacokinetics (PK) of OV101 following a single 5 mg dose of OV101 in adolescents with FXS or AS. Secondary objectives are to determine the safety and tolerability of a single 5 mg dose of OV101 in adolescents with FXS or AS.

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.

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.

The Fragile X syndrome (FXS) was first described by Dr. Martin and Dr. Bell in 1943, in families with several patients affected by sex-linked mental disability. This disorder is the most common cause of inherited mental disability. The prevalence of the Fragile X syndrome has been established at 1 in 2,500 males and 1 in 4000 females. Despite moderate to severe mental retardation, fragile X patients exhibit macroorchidism, an elongated face, long ears, connective tissue dysplasia, hyperactivity, autistic-like and stereotypical behaviours, speech delay and increased sensory sensitivity. Objective: To evaluate the effect of the combination of the antioxidant Ascorbic acid and tocopherol, as therapy of the Fragile X Syndrome in young males. Hypothesis: It is proposed that part of the pathophysiology of the central nervous system in the animal model of the fragile X syndrome may be determined by oxidative stress. In addition, Fragile X patients showed a significantly low level of ascorbic acid in plasma. The biochemical characteristics of oxidative stress may be reversed in the FMR1-KO mice, by a chronic treatment with antioxidant compounds such as tocopherol or melatonin, it may also normalize several hallmarks of the Syndrome such as hyperactivity, anxiety and cognitive deficits. The normalization of the oxidative stress is proposed as a new therapeutic pathway to alleviate conditions caused by an excess of free radicals that are crucial in neurodevelopmental diseases such as autism, down syndrome and other diseases of the central nervous system.

The study objective is to explore the efficacy, safety and tolerability of STX209 for treatment of irritability in subjects with FSX. We hypothesize that STX209 will improve irritability and other typical problem behaviors associated with fragile X syndrome. We also hypothesize that STX209 will be safe and well tolerated.
