The trial is a Phase 1 Single Dose PK Study in Adolescent Subjects with Fragile X syndrome (FXS) or Angelman syndrome (AS).
- The primary objective of the study is to evaluate the pharmacokinetics (PK) of OV101 following a single 5 mg dose of OV101 in adolescents with FXS or AS.
- Secondary objectives are to determine the safety and tolerability of a single 5 mg dose of OV101 in adolescents with FXS or AS.

- Measurement of maximum plasma concentration achieved following a single dose of OV101 [ Time Frame: 10 hours ]Maximum plasma concentration (Cmax)
- Measurement of time of maximum plasma concentration following a single dose of OV101 [ Time Frame: 10 hours ]Time after administration of drug when maximum plasma concentration is reached (Tmax)
