The total number of participants with laboratory test abnormalities was assessed. Clinical laboratory tests included hematology, chemistry, urinalysis and some other tests (including follicle-simulating hormone[FSH], urine drug screening, hepatitis B surface antigen [HBsAg], hepatitis B core antibody [HBcAb], hepatitis C virus antibody [HCVAb] and human immunodeficiency virus [HIV]. Clinical significance was judged by the investigator.

A full physical examination included head, ears, eyes, nose, mouth, skin, heart and lung examinations, lymph nodes, gastrointestinal, musculoskeletal, and neurological systems. The limited or abbreviated physical examination focused on general appearance, the respiratory and cardiovascular systems, as well as towards participant reported symptoms. Clinical significance was judged by the investigator.

Criteria for potentially clinically important changes in vital signs were defined as: supine and standing systolic blood pressure (SBP) of less than (<90) millimeters of mercury (mm Hg) or change in supine and standing SBP more than or equal to (>=) 30 mm Hg; supine and standing diastolic blood pressure (DBP) of < 50 mm Hg or change in supine and standing DBP of >= 20 mm Hg; supine and standing pulse rate of < 40 or >120 beats per minute (bpm). Figure "99999" signifies data not measurable/applicable. Maximum Decrease is abbreviated as Max.Dec., and Maximum Increase is abbreviated as Max.Inc. n is the number of participants contributing to the parameter, not applicable is abbreviated as N/A.

PR interval was the interval between the start of the P wave and the start of the QRS complex, corresponding to the time between the onset of the atrial depolarization and onset of ventricular depolarization. Criteria for potentially clinically important changes (chg) in ECG were defined as: absolute values of PR interval >=200 to <220 msec, >=220 to <240 msec, >=240 to <260 msec and >=260 msec. Increase from baseline >=40, <60, >=60 and <80, >=80, and relative change from baseline >25%. The beginning of the Q wave to the end of the T wave corresponding to electrical systole (QT) interval corrected using the Fridericia formular (QTCF) of 450 to <480 msec, 480 to <500 msec and >=500 msec, or an increase of 30 to <60 msec of >=60 msec. Maximum is abbreviated as Max.

Participants abstained from all concomitant treatments, except for the treatment of adverse events. Limited use of non-prescription medications that were not believed to affect participant safety or the overall results of the study might be permitted on a case by case basis following approval by the sponsor. All participants were questioned about concomitant treatment at each clinic visit. Treatments taken within 28 days before the first dose of study investigational product were documented as a prior treatment. Treatment taken after the first dose of study investigational product were documented as concomitant treatments. Females taking hormone replacement therapy might be eligible to participate in this study if they were willing to discontinue therapy at least 28 days prior to the first dose of study treatment and remained off hormonal therapy for duration of the study. Clinical significance was judged by the investigator.

An adverse event (AE) was any untoward medical occurrence in a clinical investigation participant administered a product or medical device; the event need not necessarily have a casual relationship with the treatment or usage. A serious adverse event (SAE) was any untoward medical occurrence at any dose that: 1) resulted in death; 2) was life threatening (immediate risk of death); 3) required inpatient hospitalization or prolongation of existing hospitalization; 4) resulted in persistent or significant disability/incapacity (substantial disruption of the ability to conduct normal life functions); 5) resulted in congenital anomaly/birth defect. TEAE included both non-serious adverse events and serious adverse events.
