- •Clinically significant surgery within 4 weeks prior to the administration of the study medication.
- •Any clinically significant abnormality found during medical screening.
- •Subjects with a history of renal, hepatic or cardiovascular disease, tuberculosis, epilepsy, asthma, diabetes, psychosis or glaucoma will not be eligible for this study.
- •Any reason which, in the opinion of the medical sub-investigator, would prevent the subject from participating in the study.
- •Abnormal laboratory tests judged clinically significant.
- •Positive urine drug screen at screening.
- •Positive testing for hepatitis B, hepatitis C or HIV at screening.
- •ECG abnormalities (clinically significant) or vital sign abnormalities (systolic blood pressure lower than 90 or over 140 mmHg, or diastolic blood pressure lower than 50 or over 90; or heart rate less than 50 bpm) at screening.
- •Subjects with BMI ≥ 30.
- •History of significant alcohol abuse within six months of the screening visit or any indication of the regular use of more than two units of alcohol per day (1 Unit - 150 mL of wine or 360 mL of beer or 45 mL of alcohol 40%).
