- Major surgery within 28 days before first dose (except local palliative surgery)
- History of organ transplant including stem cell transplant
- Uncontrolled illness such as active infection, heart failure, unstable angina, lung disease, severe gastrointestinal conditions, active pneumonitis, or psychiatric/social issues limiting compliance
