This is the first study of SRX246 in humans, and is being conducted to begin to establish a safety profile of orally administered SRX246.

This protocol represents the first in human study of SRX246, and is being conducted to begin to establish a safety profile, and collect human tolerability and pharmacokinetic data of orally administered SRX246.

11. Any clinically significant abnormality on screening 12-lead ECG (e.g., heart block, conduction disorders, ventricular and/or atrial arrhythmias).
12. Any other condition or clinically significant abnormal findings on the physical examination, medical history, or clinical laboratory results during screening that, in the opinion of the Principal Investigator or the Physician Sub-Investigator, would make the subject unsuitable for the study or put them at additional risk.
