2. Patient has a current history of alcohol use which in the opinion of the investigator would preclude participation in the study

3. Patient has a current history of drug abuse

4. Patient has donated blood or blood products within 30 days prior to screening

14. Patient has a supine resting heart rate ≥ 100 beats per minute after 3 minutes rest

15. Patient has an Modification of Diet in Renal Disease (MDRD) estimate of Glomerular Filtration Rate (GFR) ≤ 35 ml/min/1.73 m2

16. Patient has a potassium < 3.5 mEq/L or > 5.5 mEq/L

17. Patient has a sodium ≤ 133 mEq/L

18. Patient has a urea > 15 mmole/L

19. Patient has a troponin I or T at screening that is detectable at the investigative site's clinical laboratory

20. Patient has a hemoglobin < 11 gm/dL in males or < 10 gm/dL in females

21. Patient has an alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALKP) or total bilirubin (TBILI) > 3 times the upper limit of normal

22. Patient is, in the opinion of the investigator, not suitable to participate in the study
