• Untreated clinically significant hypo- or hyperthyroidism; treated hypo- or hyperthyroidism should be stable for at least 8 weeks prior to Screening
• History of myocardial infarction or unstable angina within 6 months before Screening
• Cardiovascular disease history including symptomatic hypotension (supine systolic blood pressure [SBP] <90 mmHg or supine diastolic blood pressure [DBP] <60 mmHg), symptomatic orthostatic hypotension (orthostatic change in SBP >20 mmHg or DBP >15 mmHg), or hypertension (supine SBP >160 mmHg or supine DBP >95 mmHg ) or significant cardiac arrhythmia (in the judgment of the Investigator)
