Primary Outcome Measures :
  1. NIH Cognitive Toolbox [ Time Frame: Day 70 ]
  2. Clinical Global Impression - I [ Time Frame: Day 70 ]
  3. Aberrant Behavior Checklist [ Time Frame: Day 70 ]
  4. Anxiety, Depression, and Mood Scale [ Time Frame: Day 70 ]
  5. FXS Domain Specific Concerns [ Time Frame: Day 70 ]
    The Clinician/Caregiver FXS Domain Specific Concerns allows for the subject specific symptoms of concern to be assessed on an ongoing basis throughout the study. The specific concerns that correlate to the 6 domains (Clinician) or 3 Domains (Caregiver) will be assessed using a 7-point Likert scale.


Secondary Outcome Measures :
  1. To assess the safety and tolerability of each dose [ Time Frame: Day 70 ]
    Incidence of adverse events (AEs) and serious adverse events (SAEs) reported during the study. Change from baseline to Day 70 in physical examinations and assessment of vital signs.

  2. Kiddie Test of Attentional Performance (KiTAP) [ Time Frame: Day 70 ]
  3. Emotional Faces Tobii Eye Tracking [ Time Frame: Day 70 ]
  4. EEG [ Time Frame: Day 70 ]
    Resting state whole brain EEG spectra activity in 3 EEG assessments (EEG spectra, auditory evoked response potential (ERP) and Chirp modulated sweep.

  5. CGI-S [ Time Frame: Day 70 ]
