- Unstable pulmonary status or respiratory tract infection (including rhinosinusitis) requiring a change in therapy within 4 weeks prior to the first study drug administration.
- History of clinically meaningful unstable or uncontrolled chronic disease that makes the subject unsuitable for inclusion in the study in the opinion of the investigator.
- Need for supplemental oxygen during the day, and >2 L/minute while sleeping.
- History of hepatic cirrhosis with portal hypertension (e.g., signs/symptoms of splenomegaly, esophageal varices).
- History of malignancy within the past 5 years (except for basal cell carcinoma of the skin with no evidence of recurrence and/or carcinoma in situ of the cervix that has been treated with no evidence of recurrence).
- Use of any moderate and strong inhibitor(s) or inducer(s) of CYP3A4 within 4 weeks prior to the first study drug administration (e.g., clarithromycin, itraconazole, ketoconazole, telithromycin, rifampin, carbamazepine).
- Use of CFTR modulator therapy (e.g., lumacaftor and/or ivacaftor) within 4 weeks prior to the first study drug administration.
- Use of any oral corticosteroid within 3 months of screening; or history of oral corticosteroid use for ≥30 days (cumulative) within 2 years of screening.
- Abnormal liver function test at screening; defined as aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) and/or alkaline phosphatase and/or gamma-glutamyl transferase (GGT) ≥3× the upper limit of normal (ULN); and/or total bilirubin ≥1.5× the ULN.
