About
The purpose of this research study is to understand whether there is any difference in the amount of tasimelteon in the blood in smokers versus non-smokers. Additionally, this study will provide an assessment of the effect, if any, of age and body size on the safety and tolerability profile and the pharmacokinetics of tasimelteon.

Groups 1 and 2:
-
Men or women between 18 - 55 years, inclusive;
-
Smokers who test positive for cotinine at screening and baseline and smoke at least 10 cigarettes per day, for at least 6 months prior to screening (Group 1) OR Non-smokers [abstinence from smoking for at least 6 months before the screening visit and test negative for cotinine at screening and baseline (Group 2)] who are matched to Group 1 by gender, age (±10 years), and BMI category [underweight/normal (≤ 24.99), overweight (25.00-29.99), and obese (≥ 30.00)];
-
Males, non-fecund females (i.e., surgically sterilized, if procedure was done 6 months before screening or subject is postmenopausal, without menses for 6 months before screening), or females of child-bearing potential using an acceptable method of birth control for a period of 35 days before the first dosing and females must have a negative pregnancy test at the screening and baseline visits; Note 1: Acceptable methods of birth control include any one of the following: abstinence, vasectomized sexual partner, hormonal methods (i.e. pill, hormonal IUD, Depo-Provera, implants, patch, intravaginal device [NuvaRing]), intrauterine device (IUD [copper banded coils]), diaphragm, cervical cap, or condom with spermicidal jelly or foam.
-
Vital signs (after 3 minutes resting in a semi-supine position) which are within the ranges shown below:
- Body temperature between 35.0-37.5 °C;
- Systolic blood pressure between 90-150 mmHg;
- Diastolic blood pressure between 50-95 mmHg;
- Pulse rate between 50-100 bpm.
Group 3:
-
Men or women 65 years of age or older;
-
Non-smokers (abstinence from smoking for at least 6 months before the start of the study and test negative for cotinine at screening and baseline);
-
Vital signs (after 3 minutes resting in a semi-supine position) which are within the ranges shown below:
- Systolic blood pressure between 90-160 mmHg;
- Diastolic blood pressure between 50-99 mmHg;
- Pulse rate between 50-100 bpm.
Groups 1-3:
- Ability and acceptance to provide written informed consent;
- Willing and able to comply with study requirements and restrictions;
- Subjects must be in good health as determined by past medical history, physical examination, electrocardiogram, clinical laboratory tests and urinalysis;
Exclusion criteria
-
History of recent (within six months) drug or alcohol abuse as defined in DSM IV, Diagnostic Criteria for Drug and Alcohol Abuse or evidence of such abuse as indicated by the laboratory assays conducted during the Screening Visit or at Baseline;
-
Any major surgery within three months of Baseline or any minor surgery within one month;
-

-
Any condition requiring the regular use of medication except those listed in Section 8.2;
-
Use of any melatonin preparation chronically within 2 months prior to Day 1 or any drug known to cause major organ system toxicity (e.g., chloramphenicol or tamoxifen) within 60 days prior to Day 1.
-
Exposure to any investigational drug, including placebo, within 30 days or 5 half-lives (whichever is longer) of baseline;
-
Donation or loss of 400 mL or more of blood within two months prior to the Baseline Visit;
-
Significant illness within the two weeks prior to Baseline;
-
A known hypersensitivity to tasimelteon or drugs similar to tasimelteon including melatonin;

History of liver disease and/or positive for one or more of the following serological results:
- A positive hepatitis C antibody test (anti-HCV)
- A positive hepatitis B surface antigen (HBsAg)
-
A positive HIV test result

- Clinically significant gastritis, ulcers, gastrointestinal or rectal bleeding within 5 years of the screening visit;
- History of inflammatory bowel syndrome, major gastrointestinal tract surgery such as gastrectomy, gastroenterostomy, or bowel resection;
- Pancreatic injury or pancreatitis within 5 years of the screening visit;
- Clinically significant urinary obstruction or difficulty voiding within 3 years of the screening visit;

Exposure (within 2 weeks of the Baseline Visit) of any over-the-counter medications including dietary supplements and/or herbal remedies, except those listed in Section 8.2;
-
Use of any food or beverage containing grapefruit or grapefruit juice, apple or orange juice, vegetables from the mustard green family (e.g. kale, broccoli, watercress, collard greens, kohlrabi, Brussels sprouts, mustard greens) and charbroiled meats for at least 2 weeks before the Baseline Visit until the end of the study;
