* Body Mass Index (BMI) between 18.5 and 32 kg/m\^2, inclusive. BMI = weight (kg)/height (m)\^2.
* While in semi-recumbent position, has a systolic blood pressure ≤140 mmHg and diastolic blood pressure ≤90 mm Hg and a respiratory rate ≤20 breaths/min at the pre-study (screening) visit and prior to randomization.
* Judged to be in good health based on medical history, physical examination, vital sign measurements and electrocardiogram (ECG) performed prior to randomization.
* Non-smoker and/or has not used nicotine or nicotine-containing products (e.g., nicotine patch) for at least approximately 3 months.

* Unable to refrain from or anticipates the use of any medication, including prescription and non-prescription drugs or herbal remedies beginning approximately 2 weeks (or 5 half-lives) prior to administration of the initial dose of study drug, throughout the study (including washout intervals between treatment periods), until the post-study visit.
