Masking: Open Label
Primary Purpose: Treatment
||An Open Label Exploratory Study to Investigate the Safety and Effects of NPL-2009 ( 50 mg - 150 mg Single Dose) on Prepulse Inhibition Tests and Continuous Performance Tasks, in Adults With Fragile X Syndrome
Primary Outcome Measures:
- The primary outcome measure for the study is that of safety and subjects will be assessed post-dose at at least hourly intervals for any signs of Adverse Events - up to allowing discharge from the unit at 6 hours post-dose [ Time Frame: 7 Days ] [ Designated as safety issue: Yes ]
Secondary Outcome Measures:
- Tolerability [ Time Frame: 7 days ] [ Designated as safety issue: No ]
