Primary Outcome Measures:
  • Change from baseline in behavioral symptoms of Fragile X Syndrome using the Aberrant Behavior Checklist - Community (ABC-C) Total score in Stratum I [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change from baseline in behavioral symptoms of Fragile X Syndrome using the ABC-C Total score in Stratum II [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Safety and tolerability as measured by changes in vital signs, ECGs, laboratory values and percentages of adverse events and serious adverse events [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]
  • Global improvement of symptoms in Fragile X using the Clinical Global Impression-Improvement (CGI-I) scale [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Change from baseline in irritability, lethargy/social withdrawal, stereotypic behavior, hyperactivity, and inappropriate speech assessed by the individual subscales of the ABC-C scale [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • The proportion of patients with clinical response, where response is defined as a reduction of at least 25% from baseline in the ABC-C total score and a score of 1 (very much improved) or 2 (much improved) on the CGI-I scale [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
