Active clinical trials for "Fragile X Syndrome"

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.

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.

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 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 objectives of this study are to determine the safety and tolerability of single oral doses of STX107 and to determine basic pharmacokinetic (PK) parameters following single oral doses of STX107 when administered via an oral suspension

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.

This is a single center study at the UC Davis MIND Institute in patients age 3.5-16 years of age with fragile X syndrome (FXS), funded by a National Fragile X Foundation Grant. It is a controlled trial of minocycline, an antibiotic commonly used in children for infection or for treatment of neurodegenerative disorders. We are investigating its use in FXS because it lowers matrix metalloproteinase 9 (MMP9) levels, which are high in FXS, and it also strengthens brain connections in the animal models of FXS. We hypothesize that minocycline will likely be helpful for language, behavior and/or cognition in fragile X patients.

This is an open label exploratory study to investigate the safety and effects of a single dose of NPL-2009(50 mg - 150 mg) on Prepulse Inhibition (PPI) Tests and Continuous Performance Tasks (CPT) in adults with Fragile X Syndrome
