3. A Jet Lag Symptom Scale (JLSS) total score of ≥ 4 AND at least one night of Sleep Efficiency ≤ 85% during the first two thirds of any night.

a. Note: Women using hormonal methods of birth control must use an additional method of birth control during the study and for one month after the last dose. Valid passport for international travel and fluent in English
7. In good health as determined by a medical and psychiatric history, physical examination, Electrocardiogram, and serum chemistry and hematology
8. Willing to comply with study procedures and restrictions with fixed sleep time and wake time during the study and to attend regularly scheduled clinic visits as specified in this protocol

12. Must have a target daily bedtime that on average occurs between 21:00 and 00:00
13. eDiary and actigraphy must demonstrate, on average, that the total sleep time each night is between 7 to 9 hours during screening during the week preceding V2;
14. eDiary and actigraphy must demonstrate that on most nights (5 of the 7 days) the subject’s habitual bedtime does not differ by more than 2 hours during screening the week preceding V2. |
