• P-glycoprotein (P-gp) inhibitors within 7 days prior to day 1 of protocol therapy.
• Narrow therapeutic index P-gp substrates within 7 days prior to day 1 of protocol therapy.

Más betegség

• Active fungal infection or bacterial sepsis.
• Class III/IV cardiovascular disability according to the New York Heart Association classification.
• Participants with clinically significant arrhythmia or arrhythmias not stable on medical management within two weeks of enrollment. Subjects with controlled, asymptomatic atrial fibrillation can enroll.
• History of acute cardiovascular ischemic event, i.e., myocardial infarction or unstable angina within 6 months of enrollment.
• Unable to swallow capsules, has a partial or small bowel obstruction, or has a gastrointestinal condition resulting in a malabsorptive syndrome (e.g. small bowel resection with malabsorption).
• Active peptic ulcer disease.
• Other active malignancy except for localized skin cancer, bladder, prostate, breast or cervical carcinoma in situ.
• Any other condition that would, in the Investigator's judgment, contraindicate the patient's participation in the clinical study due to safety concerns with clinical study procedures.

Laborértékek

• Current or planned use of agents that prolong or suspected to prolong QTc.
• History of unexplained syncope, significant histories of CAD (requiring revascularization by percutaneous coronary intervention [PCI] or coronary artery bypass grafting [CABG]), cardiomyopathy (ejection fraction [EF] < 50%).
