- Subjects' overall health must be sufficiently stable to complete the study requirements based on the screening physical examination (defined as the absence of any clinically relevant abnormalities), medical history, 12-lead ECG, and clinical laboratory values (hematology, serum chemistry and urinalysis), and vital signs (heart rate, respiratory rate, and blood pressure) that have been conducted within 30 days of Visit 2 (randomization). If any of the hematology, chemistry, or urinalysis results are not within the laboratory's reference range, then the subject can be included only if the investigator judges the deviations to be not clinically significant.
