- Current active pneumonitis or any history of pneumonitis requiring steroids (any dose) or immunomodulatory treatment within 90 days of planned start of the study.
- Any clinically significant concomitant disease or condition (such as transfusion-dependent anemia or thrombocytopenia) that could interfere with, or for which the treatment might interfere with, the conduct of the study or that would, in the opinion of the Investigator, pose an unacceptable risk to the patients in this study.
- Any psychological, familial, sociological, or geographical condition potentially hampering compliance with the study requirements and/or follow-up procedures. Those conditions should be discussed with the patients before study entry.
- High medical risk due to a serious, uncontrolled medical disorder; nonmalignant systemic disease; or active, uncontrolled infection (including COVID-19). Examples include, but are not limited to, uncontrolled ventricular arrhythmia, recent (within 90 days) myocardial infarction, uncontrolled major seizure disorder, unstable spinal cord compression, superior vena cava syndrome, active uncontrolled coagulopathy, bleeding disorder, or any psychiatric disorder that prohibits obtaining informed consent.
- Uncontrolled hypertension defined as SBP>180 and DBP>100 should receive antihypertensive medical therapy for blood pressure control (to achieve SBP<160 and DBP <90) before being enrolled in the study.
- Is pregnant, breastfeeding, or expecting to conceive children while receiving study treatment and/or for up to 180 days after the last dose of study treatment.
Presence of hepatitis B surface antigen or a positive hepatitis C virus (HCV) antibody test result at Screening or within 3 months prior to first dose of study treatment. Patients with presence of hepatitis B core antibody should also be excluded.
- NOTE: Patients with chronic hepatitis B virus (HBV) infection, who meet the criteria for anti-HBV therapy may be eligible if the participant is on a suppressive antiviral therapy prior to initiation of cancer therapy.
- NOTE: Patients with positive HCV antibody due to prior resolved disease can be enrolled only if a confirmatory negative HCV RNA PCR is obtained. Also, patients with a history of HCV infection may be eligible if they have both: completed curative therapy, have an HCV viral load <quantifiable limit.
