Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the long-term safety and tolerability of AFQ056 in adolescent patients with FXS as assessed by: • Incidence and severity of adverse events and serious adverse events • Changes in vital signs, laboratory assessments, and ECGs • Monitoring the hypothalamic-pituitary-adrenal/thyroid axis function and childhood developmental milestones ; Secondary Objective: To evaluate the long-term efficacy of AFQ056 treatment in both FM (Fully Methylated) and PM (Partially Methylated) patients with FXS as assessed by: • Change from baseline in the Aberrant Behavior Checklist – Community edition (ABC-C) total score and subscale scores • Rating of global improvement of symptoms in Fragile X patients using the Clinical Global Impression - Improvement (CGI-I) scale. • Change from baseline in the Repetitive Behavior Scale – Revised (RBS-R) total score and subscale scores • Change from baseline in the Social Responsiveness Scale (SRS) total score • To collect pharmacokinetic data of AFQ056 in the target patient population ; Primary end point(s): 1) Number of patients having any adverse events (AE) by primary system organ class and preferred term during the 24 months of the study. Adverse events will be summarized by presenting the number of patients having any AE by primary system organ class and/or preferred term. 2) Changes in vital signs. Pulse and Blood pressure will be taken sitting after five minutes. Temperature will also be taken. 3) Changes in weight. Body weight (to the nearest 0.1 kilogram in indoor clothing, but without shoes) will be measured. 4) Changes in height. Height in centimeters (cm) will be measured. 5) Changes in standard lab | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1) Change in the Aberrant Behavior Checklist-Community edition (ABC-C) The ABC-C is a symptom checklist for assessing problem behaviors of children and adults with intellectual disability. The ABC-C is comprised of 5 sub-scales (irritability, lethargy/social withdrawal, stereotypic behavior, hyperactivity and inappropriate speech) plus total score. The questionnaire is completed by the caregiver by attributing a score from 0 (“not a problem”) to 3 (“problem is severe in degree”) to each item of the questionnaire; the total score ranks from 0 to 174. Summary and change from baseline in the ABC-C total and subscale scores will be reported. 2) Change in the Clinical Global Impression Score – Severity/Improvement (CGI-S/I) scale. The CGI-I is used to assess treatment response in psychiatric patients. The scale is divided into two parts, one assessing the severity of illness (CGI-S) and one assessing the improvement (CGI-I). It is a clinician-rated scale. The CGI-I reports the global changes of the symptoms rated on a seven-point scale (from “very much improved” to “very much worse”). CGI-I will be summarized by visit. CGI-I will be evaluated using the extension study baseline visit as the reference visit. 3) Change in the Repetitive Behavior Scale – Revised (RBS-R). The RBS-R is a rating tool that captures the breadth of repetitive behavior: ritualistic behavior, sameness behavior, stereotypic behavior, self-injurious behavior, compulsive behavior, and restricted interests. Every behavior falling into one of the above categories 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. It is a questionnaire filled by the caregivers. 4) Change in the Social Responsiveness Scale (SRS) total score. The SRS distinguishes autism spectrum conditions from other p | — |
