Korábbi kezelés

• Existence of other active malignant tumors within 5 years or at the same time. Plan to perform or have undergone an organ or bone marrow transplant. Myocardial infarction and poorly controlled arrhythmias occurred within 6 months prior to the first dose.
• Patient with previous or current interstitial pneumonia, pneumoconiosis, radiation pneumonitis, drug-associated pneumonia, severely impaired lung function, etc.
• Patients who have previously received other antibody/drug treatments for immune checkpoints, such as PD-1, PD-L1, and CTLA4 treatments.

Más betegség

• Human immunodeficiency virus (HIV) infection.
• Patients with active tuberculosis.
• Have diseases that may increase the risk of participating in the study and using the study medications, or other severe, acute, and chronic diseases and therefore are judged by the investigator to be unsuitable for clinical studies.
