13. Any acute, clinically significant treatment-related toxicity (caused by previous treatment) must have been alleviated to ≤ 1 grade before entering the study, except hair loss;
14. HIV antibody test results were negative at the time of screening;
15. Patients with active hepatitis B virus (HBV) infection: HBV DNA \< 2000 IU/mL obtained within 28 days before the start of study treatment, and at least 7 days of anti-HBV treatment (according to the local standard treatment, such as entecavir) before the study and willing to continue treatment during the study
16. Women of childbearing age must have a negative pregnancy test (beta HCG) before starting treatment, women and men of reproductive age (having sex with women of reproductive age) must agree to use effective contraceptive measures during treatment and 6 months after the last dose of treatment.

Exclusion Criteria:

1. History of soft meningitis;
2. Current or previous autoimmune disease or immune deficiency, including but not limited to myasthenia gravis, myositis, autoimmune hepatitis, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, antiphospholipid antibody syndrome, Wegener's granulomatosis, Sjogren's syndrome, Guillain-Barre syndrome, or multiple sclerosis, with the following exceptions: patients with autoimmune hypothyroidism and receiving thyroid hormone replacement therapy were eligible to participate in the study; patients with controlled type 1 diabetes receiving insulin therapy were eligible to participate in the study; patients with eczema, psoriasis, chronic lichen simplex, or vitiligo with dermatologic clinical manifestations only (e.g., patients with psoriasis arthritis were excluded) were eligible to participate as long as all of the following conditions were met: 1. Rash area must be \< 10% of body surface area; 2. The disease was well controlled at baseline and required only low-potency topical glucocorticoids. 3. In the past 12 months, the original condition did not appear to require psoralen plus A-band ultraviolet radiation, methotrexate, vitamin A acid, biological agents, oral calcineurin inhibitors or highly active or oral corticosteroids treatment of acute exacerbation;
3. Idiopathic pulmonary fibrosis, organizing pneumonia (e.g., obliterative bronchitis), drug pneumonia or idiopathic pneumonia or evidence of active pneumonia on screening chest computed tomography (CT) scan; A history of radiation pneumonitis in the area of allowable radiation (fibrosis);

Patients who have had a corresponding examination within 6 months prior to starting study treatment do not need to repeat the examination;
15. Coinfection with HBV and HCV. Patients with a history of HCV infection and a negative PCR result for HCV RNA were considered not infected with HCV;

A stable dose of anticonvulsant therapy was allowed. Asymptomatic patients with newly detected CNS metastases at screening, after radiotherapy or surgery, were eligible to participate in the study without the need for repeat screening brain scans;
