- Laboratory parameters demonstrating no clinically significant abnormalities, as determined by the Investigator. A total bilirubin outside the normal range may be acceptable if total bilirubin does not exceed 1.5 × ULN conjugated bilirubin (with the exception of a participant with documented Gilbert syndrome).

- History of clinically severe relevant cardiovascular, hepatic, renal, pulmonary, gastrointestinal, endocrine, or neurological diseases that, in the investigator's opinion, may interfere with the aim of the study or affect the subject's safety;
- Uncontrolled or acute illness that may complicate the study evaluation in the investigator's opinion;
