- Has any clinical safety laboratory result considered clinically significant and unacceptable by the Investigator during screening or on Day 1
- Received an investigational agent within 30 days or within 5 elimination half-lives, whichever is longer prior to the first dose of study drug, or are in follow-up of another clinical study prior to study enrollment
- Is unwilling or unable to limit alcohol consumption throughout the course of the study. Alcohol intake of >2 units/day is excluded during the study

- Has alanine aminotransferase (ALT) or aspartate aminotransferase (AST) >upper limit of normal (ULN) at screening
- Has total bilirubin above the ULN
- Has history of asthma or recurrent or chronic lung disease, excluding childhood asthma that has resolved
- Has history of chronic liver disease from any cause

Additional Exclusion Criteria for Patients in Part B
- Has any of the following laboratory parameter assessments at screening:
a. Alanine aminotransferase or AST =1.5× ULN
b. Total bilirubin >ULN. Patients with elevated total bilirubin that is secondary to documented Gilbert’s syndrome are eligible.
