Subjects with stable status of brain metastasis after treatment.
4. Concomitant active or suspected autoimmune disease; but patients who are in a stable state and did not require systemic immunosuppressive therapy are allowed to be enrolled.
5. A history of allogeneic organ, bone marrow transplant or stem cell transplant; A history of allogeneic organ, bone marrow or stem cell transplantation.
6. Patients with the history of or are suffering from pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, radiation pneumonia, drug-related pneumonia, severe pulmonary function impairment, etc., which may interfere with the detection and management of suspected drug-related pulmonary toxicity; patients with active tuberculosis or with a history of active tuberculosis infection ≤48 weeks prior to screening, regardless of treatment.
7. Severe cardiovascular disease, such as NYHA class III or IV congestive heart failure.
