• Has active interstitial lung disease (ILD)/pneumonitis or a history of ILD/pneumonitis requiring treatment with systemic steroids
• Infection requiring systemic antibacterial, antifungal, or antiviral therapy within 14 days before study treatment (Note: Antiviral therapy is permitted for subjects with chronic HBV or HCV infection)
• Untreated chronic hepatitis B or chronic HBV carriers with HBV DNA>500 IU/mL (or >2500 copies/mL) at screening (Note: Inactive hepatitis B surface antigen (HbsAg) carriers, treated and stable hepatitis B (HBV DNA < 500 IU/mL or < 2500 copies/mL) can be enrolled. Subjects with detectable HbsAg or detectable HBV DNA should be managed per treatment guidelines. Subjects receiving antivirals at screening should have been treated for > 2 weeks before study treatment.)
• With active hepatitis C (Note: Subjects with a negative HCV antibody test at screening or positive HCV antibody test followed by a negative HCV ribonucleic acid (RNA) test at screening are eligible. The HCV RNA test will be performed only for subjects testing positive for HCV antibody. Subjects receiving antivirals at screening should have been treated for > 2 weeks before study treatment.)
• Major surgery for any reason, except diagnostic biopsy, within 4 weeks of study informed consent and or if the subject has not fully recovered from the surgery within 4 weeks of informed consent
