Can healthy volunteers participate?
Yes
Key exclusion criteria
1. History or findings on physical examination of any significant disease or disorder which, in the opinion of the Investigator, may put the subject at risk because of participation in the study, influence the results of the study or the subject’s ability to participate in the study.
2. Clinically significant laboratory assessments at Screening or Day -1
3. Pregnant or breast feeding
4. Chronic tobacco use or vaping within 60 days prior to screening, and/or positive urine cotinine and/or exhaled carbon monoxide test at check-in.
