Must have a normal or clinically acceptable 12-lead electrocardiogram at screening. Male subjects must have a QTcF value ≤ 430 msec. Female subjects must have a QTcF value ≤ 450 msec. Exclusion Criteria: 1. History of any clinically significant and relevant neurological, gastrointestinal, renal, hepatic, cardiovascular, psychological, pulmonary, metabolic, endocrine, hematological, allergic disease, drug allergies, or other major disorders. 2. Any condition which places the subject at unacceptable risk if he or she were to participate in the study, or confounds the ability to interpret data from the study. 3.
