• Clinically significant past or current medical or surgical history that could interfere with treatment.
• Participation in an investigational drug or device study within 30 days or five half-lives, whichever is longer [90 days for biologics], prior to dosing.
• Presence of clinically significant illness or abnormality on physical examination.
• Presence of clinically significant ECG abnormality at Screening, including any QT interval corrected for heart rate (QTc) using Fridericia formula (QTcF) ≥470 msec.
• Ongoing liver disease or unexplained liver function test (LFT) elevations, defined as alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma glutamyl transferase (GGT), or alkaline phosphatase (ALP) greater than the upper limit of normal (ULN).
