Study of SRX246 Capsules in Healthy Adult Volunteers

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.

• SRX246 (Drug): single oral dose of SRX246 capsule
• Placebo (Drug): Single oral dose of placebo capsule

Primary outcomes

• To assess safety and tolerability of SRX246 at single doses ranging between 20 and 360 mg [24 hours]

Secondary outcomes

• To assess Pharmacokinetics of SRX246 at single doses ranging between 20 and 360 mg [24 hours]

6. Subject who has resting supine pulse rate greater than 100 bpm or less than 50 bpm on two consecutive measurements taken up to 10 minutes apart.
7. Subject has taken any alcohol within 48 hours of ANY study-related activities AND cannot abstain from drinking alcohol during the entire duration of the subject's study participation.

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.
