Efficacy, Safety and Tolerability of AFQ056 in Fragile X Patients - Full Text View

Purpose

This study will evaluate the safety, tolerability and efficacy of multiple doses of AFQ056 in patients with Fragile X Syndrome. The dose range will be 50 to 150 mg b.i.d. The primary read-out of efficacy is reduction in Aberrant-Behavior Checklist score.
