Primary Outcome Measures:
  • QTcF evaluated through electrocardiogram analysis (ECG) [ Time Frame: Days -1, 1 and 7 (period 1) and Days 1 and 7 (period 2-4) ]
    QTcF is a QT interval corrected for heart rate (Fridericia's formula)

Secondary Outcome Measures:
  • Evaluation of Electrocardiogram (ECG) [ Time Frame: Days -1, 1 and 7 (period 1) and Days 1 and 7 (period 2-4) ]
  • QTcI evaluated through electrocardiogram analysis [ Time Frame: Days -1, 1 and 7 (period 1) and Days 1 and 7 (period 2-4) ]
    QTcI is a QT interval corrected for individual heart rate

  • QTcB evaluated through electrocardiogram analysis (ECG) [ Time Frame: Days -1, 1 and 7 (period 1) and Days 1 and 7 (period 2-4) ]
    QTcB is a QT interval corrected for heart rate (Bazett's formula)

Enrollment: 88

Detailed Description:

Subjects will be randomized in four treatment sequences of twenty subjects each. Subjects in each treatment sequence will participate in a total of four treatment periods (A, B, C, and D) separated by washout periods of at least 7 days from completion of the prior period (Day 8) through clinical check-in (Day -1) of the next study period.

For Period 1, subjects will be admitted to the clinical research unit on Day -2. For each subsequent study period, subjects will be admitted to the clinical research unit on Day -1. Subjects will be discharged from the unit after completing procedures on Day 8 of each period. Subjects will receive a follow-up telephone call 7-10 days after their last clinic day (Period 4\Early Discontinuation [ED]).

  • The subject has used tobacco-containing products and nicotine or nicotine-containing products within past six months
  • The subject is unable to tolerate a controlled, quiet study conduct environment, including avoidance during specified times (e.g., prior to and in ECG extraction windows) of music, TV, movies, games and activities that may cause excitement, emotional tension or arousal
  • The subject is unwilling to comply with study rules, including attempting to void at specified times (e.g., prior to ECG extraction windows), remaining quiet, awake, undistracted, motionless and supine during specified times, and avoiding vigorous exercise as directed
  • The subject is unable to tolerate study-specific diet
  • The subject has a history or evidence of any clinically significant cardiovascular, endocrinologic, hematologic, hepatic, immunologic, metabolic, urologic, pulmonary, neurologic, dermatologic, psychiatric, renal, and/or other major disease or malignancy (excluding non-melanoma skin cancer)
  • The subject has a history of clinically significant allergic conditions or anaphylactic reactions
  • The subject has any condition possibly affecting drug absorption
  • The subject has a history of consuming more than 14 units of alcoholic beverages per week within 6 months prior to screening or has a history of alcoholism or drug/chemical/substance abuse within past 2 years
  • The subject has/had febrile illness or symptomatic, viral, bacterial (including upper respiratory infection), or fungal (non-cutaneous)infection within 1 week prior to clinic check in for any treatment period
  • The subject is known positive for human immunodeficiency virus (HIV) antibody

  • The subject has received an experimental agent within 30 days or 10 half-lives, whichever is longer, prior to study drug administration
  • The subject is participating in another clinical trial or has participated in another dose group of the current trial
  • The subject has had any significant blood loss, donated one unit (450 mL) of blood or more, or received a transfusion of any blood or blood products within 60 days or donated plasma within 7 days prior to clinic admission
