• Participants must weigh at least 50 kg to participate in the study, and must have a body mass index (BMI) within the range of 18.0 - 30.0 kg/m2. BMI = Body weight (kg) / [Height (m)]2
• At screening and baseline, vital signs (systolic and diastolic blood pressure and pulse rate) will be assessed in the supine position after the participant has rested for at least three (3) minutes, and again in the standing position. Supine vital signs should be within the following ranges:
• oral body temperature between 35.0-37.5 °C
• systolic blood pressure, 90-139 mmHg
• diastolic blood pressure, 50-89 mmHg
• pulse rate, 40-90 bpm

Exclusion Criteria:
