Primary Outcome Measures
Change From Baseline in Behavioral Symptoms of Fragile X Syndrome Using the Aberrant Behavior Checklist-Community Edition (ABC-CFX) Total Score in Stratum I Patients Exposed to AFQ056 100 mg Bid
The Aberrant Behavior Checklist-Community edition (ABC-C) is a 58-item, caregiver-rated symptom checklist for assessing problem behaviors of children and adults with mental retardation at home, in residential facilities, and work training centers. The assessment was done by attributing to each item a score from 0 ("not at all a problem") to 3 ("problem is severe in degree") and the total score ranks from 0 to 174. The data collected from the full, 58-item ABC-C were analyzed according to the modified FXS ABC-C algorithm (ABC-CFX) for which 55 items and six subscales (irritability, lethargy/withdrawal, stereotypic behavior, hyperactivity, inappropriate speech and social avoidance) plus the total score were considered, and for which the total score ranks from 0 to 165. Stratum I included patients whose Fragile X Mental Retardation 1 (FMR1) gene was fully methylated
Secondary Outcome Measures
Change From Baseline in Behavioral Symptoms of Fragile X Syndrome Using the ABC-CFX Total Score in Stratum II Patients Exposed to All 3 Doses of AFQ056
The ABC-C is a 58-item, caregiver-rated symptom checklist for assessing problem behaviors of children and adults with mental retardation at home, in residential facilities, and work training centers. The assessment was done by attributing to each item a score from 0 ("not at all a problem") to 3 ("problem is severe in degree") and the total score ranks from 0 to 174. The data collected from the full, 58-item ABC-C were analyzed according to the modified FXS ABC-C algorithm (ABC-CFX) for which 55 items and six subscales (irritability, lethargy/withdrawal, stereotypic behavior, hyperactivity, inappropriate speech and social avoidance) plus the total score were considered, and for which the total score ranks from 0 to 165. Stratum II included patients whose FMR1 gene was partially methylated
Change From Baseline in Behavioral Symptoms of Fragile X Syndrome Using the ABC-CFX Total Score in Stratum I Patients Exposed to the Two Lower Doses of AFQ056 (25 mg Bid and 50 mg Bid)
The ABC-C is a 58-item, caregiver-rated symptom checklist for assessing problem behaviors of children and adults with mental retardation at home, in residential facilities, and work training centers.

The ABC-C is a 58-item, caregiver-rated symptom checklist for assessing problem behaviors of children and adults with mental retardation at home, in residential facilities, and work training centers. The assessment was done by attributing to each item a score from 0 ("not at all a problem") to 3 ("problem is severe in degree") and the total score ranks from 0 to 174. The data collected from the full, 58-item ABC-C were analyzed according to the modified FXS ABC-C algorithm (ABC-CFX) for which 55 items and six subscales: irritability (range 0 to 54); lethargy/withdrawal (range 0 to 39); stereotypic behavior (range 0 to 18); hyperactivity (range 0 to 30); inappropriate speech (range 0 to 12); and social avoidance (range 0 to 12) plus the total score (range 0 to 165) were considered. A negative change represents improvement. Stratum I included patients whose FMR1 gene was fully methylated

Change From Baseline in Repetitive Behaviors Assessed Using the Repetitive Behavior Scale - Revised (RBS-R) Total and Subscale Scores in Stratum I
The Repetitive Behavior Scale - Revised (RBS-R) is a rating tool that captures the breadth of repetitive behavior. It is a 43-item questionnaire filled by the caregivers. Each behavior assessed is rated from 0 (behavior does not occur) to 3 (behavior occurs and it is a severe problem). The total score ranks from 0 to 129. The behaviors are grouped into six domains: ritualistic behavior (range 0 to 18); sameness behavior (range 0 to 33); stereotypic behavior (range 0 to 18); self-injurious behavior (range 0 to 24); compulsive behavior (range 0 to 24); and restricted interests (range 0 to 12). A negative change represents improvement. Stratum I included patients whose FMR1 gene was fully methylated
