You may not qualify if:

• \. Subjects have received CD70-targeted therapy in the past; 2. Subjects who have received allogeneic transplantation in the past and require continuous use of immunosuppressive agents; 3. Patients who have primary central nervous system (CNS) malignant tumor or patients with active CNS metastases who have failed local treatment (radiotherapy or surgery), but the following patients are allowed to be enrolled: a. asymptomatic brain metastases; b. clinically stable (i.e. no imaging progression was seen 4 weeks before the first dose, and any neurological symptoms had returned to baseline levels) and no treatment for brain metastases was required; 4. Subjects who have serious organic disease, or the investigator judges that it is not suitable to participate in the study due to the combination of other serious diseases:
