- Willing and able to comply with study requirements and restrictions;

- Clinically significant deviation from normal in vital signs measurements, or physical examination findings at screening or baseline as determined by the clinical investigator;
- Pregnant or lactating females;
- Smoke more than 10 cigarettes/day;
- Exposure to any investigational drug other than tasimelteon, including placebo, within 30 days, 5 half-lives, or the exclusion period given by a previous study in which the patient has participated in, whichever of the three scenarios is longer.
