Pharmacodynamic parameters (Digit Vigilance, Digit Symbol Substitution Task, Hopkins Verbal Learning Test Revised , Divided Attention Test, Balance Platform Test, Choice Reaction Time, Visual Analog Scale) as measured by peak change from baseline [ Time Frame: Days 1, 8, 15, 22: at pre-dose, 0.5, 1, 1.5, 2, 3, 4, 8, 12, and 24 hours after dose ]
Differences will be calculated for the following comparisons:
  • Ethanol Alone vs. Placebo-Placebo
  • Ethanol Alone vs. Tasimelteon + Ethanol
  • Tasimelteon Alone vs. Placebo-Placebo
  • Tasimelteon Alone vs. Tasimelteon + Ethanol

  • Pharmacokinetic parameters (AUC, Cmax, Tmax) of tasimelteon, tasimelteon's metabolites, and ethanol [ Time Frame: Approximately Days 1, 8, 15, and 22: predose, 0.25, 0.75, 1, 1.5, 2, 3, 4, 8, 12, and 24 hours after dosing ]
  • Safety and tolerability as measured by spontaneous reporting of AEs, and clinically significant changes in laboratory parameters, ECG parameters, and vital signs [ Time Frame: Screening (approximately Day -10), Days -2, -1, 1, and approximately Days 8, 15, 22, 23 ]
  • The Columbia-Suicide Severity Rating Scale will be used to assess suicidal behavior and ideation. [ Time Frame: once per day at Screening (approximately day -7),Day -1 (baseline), approximately Days 1, 8, 15, 22 and 23 (end of study) ]

Evaluation of the Pharmacodynamic and Pharmacokinetic Interactions of Tasimelteon and Ethanol
A Randomized, Double-mask, Four-period Crossover Study in Healthy Subjects to Evaluate the Pharmacodynamic and Pharmacokinetic Interactions of Tasimelteon and Ethanol
The purpose of this research study is to understand if there is any difference in the effects of tasimelteon when it is taken alone or in combination with alcohol. This research study is also being done to understand if there is any difference in the amount of tasimelteon (and its breakdown products) or alcohol in the blood when taken alone or together. Finally, the study will also look at the safety and tolerability (how acceptable it is) of tasimelteon.
Alcohol is a drug that gets absorbed into the bloodstream quickly. The blood carries the alcohol to the brain where it slows down the messages in the brain (alcohol is a depressant). Alcohol affects a person's memory, behaviour, concentration, alertness (your thought process is slower), and coordination (your movements become clumsy). The intended effect of tasimelteon is to cause sleepiness. Sleepiness may result in similar effects on memory, concentration, alertness, and coordination as alcohol. There is the possibility taking tasimelteon and alcohol together can make these effects stronger or worse.
