- Hypertension, with confirmed systolic blood pressure (BP) greater than 140 mm Hg or confirmed diastolic BP greater than 90 mm Hg, measured after 5 minutes of rest at screening.
- Hypotension, with confirmed systolic BP less than 90 mm Hg.
- Resting heart rate (HR) less than 45 bpm or greater than 100 bpm at screening.

If the median QTcF value from the 3 tracings exceeds the limits stated, the subject is disqualified.
- Any history of malignancy ever, except low-grade skin cancer (ie, basal cell carcinoma thought to be cured).
- History of drug abuse, alcohol abuse, or significant psychiatric history according to the investigators' judgment within 12 months before Screening.

- Consumption of alcohol within 24 hours before study product administration.
- Use of nicotine-containing products within 30 days before study product administration through the final study visit.
Positive drug screen*, positive cotinine screen, or positive breathalyzer test for alcohol at Screening or admission (Day -1).
*Cannabinoids, amphetamines, barbiturates, cocaine, opiates, benzodiazepines and phencyclidine. Subjects should be notified by phone not to consume any poppy seeds within 24 hours before the screening urine test to avoid a false positive opioid test result.

Total WBC and platelet counts, hemoglobin*, total bilirubin*, alanine/aspartate aminotransferase and sodium* are Grade 1 or higher** at Screening visit.
*For sodium; lower limit values of 133-134 mmol/L will be allowed at Screening and Day -1/baseline. If the result at screening is 132 mmol/L or below , the participant will be scheduled to repeat the test during the screening period but before Day-1 to assure that it is at or > 133 mmol/L Repeated sodium values of 132 mmol/L and below are exclusionary. Potential subjects excluded prior to Protocol Version 6.0 with Grade 1 sodium values may be rescreened.
For hemoglobin; a lower limit of 13.5 g/dL for males and 11.5 mg/dL for females is allowable at Screening. Hemoglobin values of 13.4 mg/dL and below for males and 11.4 mg/dL and below for females are exclusionary at Screening.
For total bilirubin; upper limit values of 1.2 mg/dL will be allowed at Screening and Day -1/baseline provided the AST and ALT are within normal limits. Total bilirubin values of 1.3mg/dL and above are exclusionary. Potential subjects excluded prior to Protocol Version 6.0 with bilirubin values below the Version 6.0 upper limit may be rescreened.
**Grade 1 or higher toxicity, see Appendix C or Appendix D. Safety laboratory tests drawn on Day -1 or Screening if within 48 hours of planned dosing will serve as baseline values. Day -1 laboratory tests with a Grade 1 severity, other than those noted above, will not exclude subjects from participation.
