3. Mentally or legally incapacitated, has significant emotional problems at the time of Screening Visit or expected during the conduct of the study, or has a history of a clinically significant psychiatric disorder that would impact the subjects ability to participate in the trial according to the Investigator.
4. Fever (body temperature >38°C) or symptomatic viral or bacterial infection within 2 weeks prior to screening; evidence of intestinal infection within 30 days prior to screening.
