Fragile X Syndrome clinical trials at UC Davis

3 research studies open to eligible people

Showing trials for
  • A Study of Experimental Treatment With Metformin for Fragile X Syndrome

    “Learn if Metformin may be helpful for language, behavior problems, and obesity / excessive appetite in patients with Fragile X Syndrome.”

    open to eligible people ages 6-25

    This study is a controlled trial of metformin in individuals with fragile X syndrome between the ages of 6 and 25 years. Participants will be randomized in a double-blind design to either drug or placebo and will attend three visits to the study site in a 4-month period for a series of tests. The primary objectives are to assess safety, tolerability, and efficacy of metformin in the treatment of language deficits, behavior problems, and obesity/excessive appetite in individuals with fragile X syndrome.

  • A Study of the Long-Term Safety and Tolerability of Experimental ZYN002 in Children and Adolescents With Fragile X Syndrome (FXS)

    open to eligible people ages 3-18

    ZYN002 is a pharmaceutically manufactured Cannabidiol (CBD) that is developed as a clear gel that can be applied to the skin (called transdermal delivery). The gel will be applied to clean, dry, intact skin of the shoulders and/or upper arms. Only participants from the ZYN2-CL-016 study who meet the inclusion criteria and none of the exclusion criteria for study ZYN2-CL-017 are eligible. Parents/caregivers will apply the study gel twice daily for the 52-week treatment period.

  • Cognitive Training for Fragile X Syndrome

    open to eligible people ages 8-18

    Individuals with fragile X syndrome (FXS) demonstrate profound executive function deficits that interfere with learning, socialization and emotion regulation. Extensive research focused on the animal models of FXS show that targeted pharmacological agents can normalize synaptic connectivity and reverse cognitive and behavioral deficits. This translational work has led to multiple national and international controlled trials in humans with FXS now underway. However, in contrast to the heavy focus on medication treatments, there have been no controlled trials to empirically-validate cognitive or behavioral interventions for FXS. The proposed study, the first non-pharmacological controlled trial for FXS, will evaluate the efficacy of Cogmed, a cognitive training program proven to enhance working memory and executive/frontal function in a variety of clinical populations. Demonstration of effective Cogmed training for FXS would represent a major advance in the field, one that may also generalize to other forms of intellectual disability. Furthermore, it is critical to determine whether the targeted pharmacological treatments can accelerate learning and cognitive development. Thus, the validation of Cogmed for FXS will provide a paradigm for testing hypotheses focused on combined efficacy of medication and cognitive training.
