Lifestyle Considerations Meals and Dietary Restrictions

1. Subjects will fast from all food and drink except water for ≥ 10 hours before morning study drug administration on Day 1.
2. Except during the periods of fasting, standard meals and snacks will be provided at the discretion of the Investigator while subjects are confined in the study site.

3. For food effect Cohort 1e:

   1. On Day 8, subjects will be provided a standard high calorie breakfast from 30 minutes before dose administration (and to be consumed entirely within that 30 minutes). The meal is to follow United States Food and Drug Administration (FDA) guidance regarding caloric content and composition. The test meal should derive approximately 150, 250 and 500 600 calories from protein, carbohydrate, and fat, respectively. An example test meal would be two eggs fried in butter, two strips of bacon, and two slices of toast with butter, four ounces of hash brown potatoes and eight ounces of whole milk. Substitutions in this test meal can be made as long as the meal provided a similar amount of calories from protein, carbohydrate and fat and has comparable meal volume and viscosity. Vegetarians may be enrolled provided that there is a consultation with a dietician regarding comparable calories, volume and viscosity.
   2. Water restrictions may be needed. No water is allowed 1 hour before and after dosing, after which time, water is allowed ad libitum.
4. Subjects will refrain from consumption of Seville oranges, grapefruit or grapefruit juice, from 48 hours before the start of study drug until after the final PK sample is obtained.
5. Subjects will refrain from diets that could alter metabolism (i.e., high protein, Slim Fast®, Nutrisystem®, etc.) within 7 days prior to dosing on Day 1.

Caffeine, Alcohol, and Tobacco

1. During each dosing session, subjects will abstain from ingesting caffeine- or xanthine-containing products (e.g., coffee, tea, cola drinks, and chocolate) for 48 hours before the start of dosing until after collection of the final pharmacokinetic (PK) and/or pharmacodynamic sample.
2. During each dosing session, subjects will abstain from alcohol for 48 hours before the start of dosing until EOS visit.
3. Active smokers and users of nicotine-containing products will be excluded from the study.

Other Restrictions Subjects will avoid strenuous physical activity (e.g. weightlifting, running, bicycling) from 24 hours prior to Day 1 until discharge from the study site and for 24 hours prior to the EOS visit.
