- Resting QTcF ≥450 msec (male) or ≥470 msec (female) at screening or baseline or inability to determine the QTcF interval
- Cardiac or cardiac repolarization abnormality
- Subjects with pre-existing conditions that may confound ability to diagnose drug-induced liver injury or subjects with factors that increase susceptibility to DILI
- Subjects who have a laboratory abnormality at Screening
- History of lymphoproliferative disease or any known malignancy or history of malignancy of any organ system within the past 5 years
- Past medical history record of, or current infection with, human immunodeficiency virus
- Any surgical, medical, psychiatric or additional physical condition that the Investigator feels may jeopardize the subject in case of participation in this study
- Pregnant or nursing (lactating) women
- Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using required methods of contraception during dosing and for 4 weeks after stopping of investigational medication.
- Sexually active males unless they use a condom during intercourse while taking drug and for 120 days after stopping investigational medication and should not father a child in this period.
- Prior exposure to ZPL389 treatment
