- Acute illness, especially any infection, within 2 weeks of dosing.
- Systolic blood pressure \< 90 or \> 140 mmHg; diastolic blood pressure \< 60 or \> 95 mmHg at screening or on Day -1 (2 rechecks are allowed) for period 1 only.

- Use of any drug in Appendix 1 (drugs known to have clinical significance in inhibiting or inducing liver enzymes involved in drug metabolism \[CYP P450\]) within 30 days prior to Day 1.
- Blood donation or significant blood loss within 56 days prior to Day 1.
- Plasma donation within 14 days prior to Day 1.
- Any use of tobacco or nicotine products within 6 months prior to Day 1.
- Any subject who received an investigational drug within 30 days or six half-lives, whichever is longer, prior to Day 1.
