Inclusion Criteria: * Male and female patients, 30 to 65 years of age inclusive, and in good health as determined by medical history, physical examination, vital signs, electrocardiogram, and laboratory tests at screening. * At screening, and at baseline vital signs (systolic and diastolic blood pressure and pulse rate) will be assessed in the sitting position after the subject has rested for at least three minutes, and again (when required) after three minutes in the standing position as outlined in the SOM. Sitting vital signs should be guided by the following ranges: * body temperature between 35.0-37.5 °C * systolic blood pressure 90-139 mm Hg * diastolic blood pressure 50-89 mm Hg * pulse rate, 40 - 90 bpm • Subjects must weigh at least 50 kg to participate in the study, and must have a body mass index (BMI) within the range of 18 - 32 kg/m2.
