Study Description

Brief Summary:

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.

Condition or disease	Intervention/treatment	Phase
Fragile X Syndrome	Drug: AF056; Drug: Placebo	Phase 2
