What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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
Time Frame: Baseline to week 12
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
Baseline to week 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Change From Baseline in Repetitive Behaviors Assessed Using the Repetitive Behavior Scale - Revised (RBS-R) Total and Subscale Scores in Stratum I
Time Frame: Baseline to week 12
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
