Eligibility

Inclusion Criteria:

• 1. Understood and Signed an informed consent form; 2. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1; Life expectancy = 3 months; 3. Local recurrence of non-keratinizing nasopharyngeal carcinoma diagnosed by histopathology and/or cytology; Clinical stage: rT2-4N0-3M0 , RII-IVa phase (AJCC eighth edition); 4. The recurrence time is more than 12 months from the end of the first course of radiotherapy, without other systemic or local anti-tumor treatment; 5. At least one measurable lesion (based on RECIST 1.1); 6. Adequate laboratory indicators; 7. No pregnant or breastfeeding women, and a negative pregnancy test.

Exclusion Criteria:

• 1. Operable patients with local recurrence, including rT2 (the tumor is confined to the surface of the parapharyngeal space, and the distance from the internal carotid artery > 0.5 cm) and rT3 (the tumor is confined to the bottom wall of the sphenoid sinus, and the distance from the internal carotid artery and cavernous sinus > 0.5 cm) ; 2.Combined diseases and medical history:

1. Accompanied by nasopharyngeal necrosis, radiation brain injury, severe neck fibrosis, or other =grade 3 radiation complications, the investigator has assessed that the risk is extremely high and not suitable for radiotherapy;

2. Has other malignant tumors within 3 years;

3. Unalleviated toxicity = grade 1 due to any previous anticancer therapy;

4. Has received major surgical treatment, open biopsy, or obvious traumatic injury within 28 days before the first administration;

5. Long-term unhealed wounds or fractures;

6. Arterial/venous thrombosis events occurred within 6 months, such as cerebrovascular accidents (including temporary ischemic attacks, cerebral; hemorrhage, cerebral infarction), deep vein thrombosis and pulmonary embolism;

7. Has drug abuse history that unable to abstain from or mental disorders;

8. Has any severe and/or uncontrollable disease. 3.Tumor-related symptoms and treatment:

1. Diagnosed local recurrence and received surgery, chemotherapy, radiotherapy or other anti-cancer therapies before first administration;

2. Has received NMPA approved Chinese patent medicines with anti-tumor indications;

3. Has received relevant immunotherapy drugs for PD-1, PD-L1, CTLA-4, etc.;

4. Uncontrollable pleural effusion, pericardial effusion or ascites that still needs to be drained repeatedly (as judged by the investigator); 4.Research and treatment related:

1. Has vaccinated with vaccines or attenuated vaccines within 4 weeks prior to first administration;

2. Have severe hypersensitivity after using monoclonal antibodies;

3. Active autoimmune diseases that require systemic treatment (such as the use of disease-relieving drugs, corticosteroids, or immunosuppressive agents) occurred within 2 years before the start of the study treatment;

4. Has immunodeficiency or received systemic glucocorticoid therapy or any other form of immunosuppressive therapy, and continue to use within 2 weeks of the first administration; 5.Has participated in other anti-tumor drug clinical trials within 4 weeks before the study; 6.According to the judgement of the investigators, there are other factors that may lead to the termination of the study.

Related Conditions & MeSH terms

• Carcinoma
• Nasopharyngeal Carcinoma

Intervention

Drug:
• TQB2450
TQB2450 is a humanized monoclonal antibody targeting programmed death ligand-1 (PD-L1), which prevents PD-L1 from binding to PD-1 and B7.1 receptors on T cell surface, restores T cell activity, thus enhancing immune response and has potential to treat various types of tumors.

Radiation:
• Intensity modulated radiotherapy
Intensity-modulated conformal radiotherapy (IMRT) is a kind of three dimensional conformal radiotherapy, which requires the dose intensity in the radiation field to be adjusted according to certain requirements.
