Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 1. Histologically or cytologically confirmed with recurrent or metastatic nasopharyngeal carcinoma which is not amenable to curative treatment with surgery and/or radiation therapy.
• 2. Age ≥ 18 years and ≤ 75 years, both genders.
• 3. Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1.
• 4. Life expectancy of at least 3 months.
• 5. Have failed for first-line platinum-based chemotherapy.
• 6. Have failed for prior treatment with PD-1 antagonists +/- chemotherapy.
• 7. Patients must have at least 1 lesion that is measurable using RECIST v1.1 criteria.
• 8. Patients must have adequate organ function (without blood transfusion, without growth factor or blood components support within 14 days before enrollment) as determined by: Absolute neutrophil count (ANC) ≥1.5×109/L; Platelet count ≥ 75×109/L; Hemoglobin ≥ 9 g/dL; serum total bilirubin (TBIL) ≤1.5 times the upper limit of normal (ULN); alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5×upper limit of normal (ULN), (for subjects with liver metastases, TBIL ≤3×ULN ; ALT and AST≤5×ULN); Creatinine ≤1.5×ULN or creatinine clearance rate≥50 ml/min (Cockcroft-Gault formula); serum albumin ≥28 g/L; Thyroid-stimulating hormone (TSH) levels ≤1×ULN (however, patients with free Triiodothyronine [FT3] or free Thyroxine [FT4] levels ≤1× ULN may be enrolled); INR, APTT≤1.5 x ULN.
• 9. All women with fertility potential must undergo a urine or serum pregnancy test during screening and the results are negative.
• Written informed consent.

You may not qualify if…

• 1.Known history of hypersensitivity to any components of the Tislelizumab formulation, or other monoclonal antibody.
• 2.Prior therapy with any anti-interleukin-4 receptor α (IL-4Rα) monoclonal antibody, anti-IgE monoclonal antibody, or other monoclonal antibodies/biological agents.
• 3.There was a history of severe bleeding, and any bleeding events with a serious grade of 3 or more in CTCAE5.0 occurred within 4 weeks before screening.
• 4.Before treatment, MRI showed that the tumor may have invaded important blood vessels (such as enclosing the internal carotid artery / vein), nasopharyngeal necrosis, or researchers have determined that the tumor is highly likely to invade important blood vessels and cause fatal massive bleeding during treatment.
• 5.Patients with abnormal blood coagulation and bleeding tendency (14 days before signing informed consent: INR is within the normal range without anticoagulant); patients treated with anticoagulants or vitamin K antagonists such as warfarin, heparin or their analogues. On the premise that the INR < 1.5, low-dose warfarin (1mg orally, once a day) or low-dose aspirin (daily dose not more than 100mg) is allowed for preventive purposes.
• 6.Arteriovenous thrombosis occurred within one year before screening, such as cerebrovascular accident (including temporary ischemic attack), deep venous thrombosis (except venous thrombosis caused by intravenous catheterization due to early chemotherapy) and pulmonary embolism.
• 7. Prior malignancy active within the previous 5 years except for locally curable cancers that have been apparently cured, such as basal cell skin cancer or carcinoma in situ of the cervix.
• 8. Join another clinical study at the same time, received any research drug within 4 weeks before the first administration of the drug.
• 9. Patients with any active autoimmune disease or a documented history of autoimmune disease such as pneumonia, colitis, hepatitis, nephritis, hyperthyroidism or hypothyroidism;
• 10. Concurrent medical condition requiring the use of immunosuppressive medications, or immunosuppressive doses of systemic or absorbable topical corticosteroids. Doses > 10 mg/day prednisone or equivalent are prohibited within 2 weeks before study drug administration.
• 11. History of immunodeficiency including seropositivity for human immunodeficiency virus (HIV), or other acquired or congenital immune-deficient disease.
• 12. Be known to have active tuberculosis.
• 13. Hepatitis B virus (HBV) >2000 IU/ml or DNA ≥ 1×10\^4/ml; or hepatitis C virus (HCV) RNA ≥ 1×10\^3/ml).
• 14. Has an active infection requiring systemic therapy.
• 15. Has known active central nervous system metastases.
• 16. Severe, uncontrolled angiocardiopathy (heart failure > class II NYHA, unstable angina, myocardial infarction within past 1 year, supraventricular or ventricular arrhythmia which need medical intervention, or QT interval male ≥ 450 ms, female ≥ 470 ms.).
• 17. Have been vaccinated with anti-tumor vaccines or have been vaccinated with live vaccines within 4 weeks before screening.
• 18. Pregnant or nursing.
• 19. Underlying medical condition that, in the Investigator's opinion, would increase the risks of study drug administration or obscure the interpretation of toxicity determination or adverse events.
