• History of alcohol or drug abuse within 12 months prior to screening which would compromise trial participation in the judgment of the investigator
• Severe medical or psychiatric condition which, in the opinion of the investigator, may increase the risk associated with trial participation or may interfere with the interpretation of trial results or affect the individual's ability to provide informed consent
