• 3. Invasive NK cell leukemia; Or central nervous system invasion;
• 4. Participated in clinical trials of other drugs within 4 weeks prior to study commencement;
• 5. Patients had received antitumor therapy 4 weeks prior to study initiation;
• 6. Patients who received allogeneic hematopoietic stem cell transplantation within 3 years prior to study drug administration (patients who received allogeneic hematopoietic stem cell transplantation more than 3 years prior to study drug administration and who do not currently have graft-versus-host reaction can be included); Received autologous hematopoietic stem cell 8 transplantation within 100 days prior to administration of the study drug;

Active hepatitis B or C infection requiring treatment should be excluded. Hepatitis B virus carriers, stable hepatitis B after drug treatment (DNA should not be more than 1000 copies /mL or 200 IU/mL and cured hepatitis C patients can be included;
• 9. Subjects who required systemic glucocorticoid therapy or other immunosuppressant therapy for a condition within 14 days prior to initiation of treatment [subjects were allowed to use topical, ocular, intra-articular, intranasal, and inhaled glucocorticoid therapy (with very low systemic absorption); It is permissible to use glucocorticoids for short-term (≤ 7 days) prophylactic treatment (e.g., contrast agent allergy) or for the treatment of non-autoimmune diseases (e.g., delayed hypersensitivity from contact allergens)
• 10. With activity, and over the past two years, need systemic treatment of autoimmune diseases (hormone replacement therapy is not considered a systemic treatment, such as type 1 diabetes, by accepting thyroid hormone replacement therapy for hypothyroidism, only need to accept the physiological doses of sugar cortical hormone replacement therapy adrenocortical function is low or pituitary function in patients with low); Patients with autoimmune diseases who have not required systemic treatment within the past two years can be enrolled;
