1. Physical examination without any clinically relevant findings.
2. Heart rate in the range of 50 to 100 bpm after 5 minutes rest in supine position or seated.
3. Body temperature, between 35.0°C and 37.7°C.
4. Three conventional 12-ECG recordings (the average of the three measurements will be used to determine eligibility) were consistent with normal cardiac conduction and function.

Additional inclusion criteria for SAD and MAD subjects who are not treated with statins: Systolic blood pressure in the range of 90 to 139 mmHg and diastolic blood pressure in the range of 60 to 89 mmHg after 5 minutes in supine position or seated.
Additional inclusion criteria for MAD subjects who are treated with statins:
1. Systolic blood pressure in the range of 90 to 160 mmHg and diastolic blood pressure in the range of 60 to 100 mmHg after 5 minutes in supine position or seated.
