Aspartate aminotransferase (AST) or alanine aminotransferase (ALT)level ≥1.5 × upper limit of normal (ULN);
-
Total bilirubin level ≥1.5 × ULN; participants with a history of Gilbert's syndrome may have direct bilirubin measured and would be eligible for this study provided the direct bilirubin level is ≤ ULN.
-
A positive COVID-19 test by polymerase chain reaction (PCR) at screening.
-
History of alcohol abuse or binge drinking and/or any other illicit drug use or dependence within 6 months of screening.
