Brief summary: This is a phase II clinical trial to evaluate the efficacy and safety of TQB2618 injection combined with Penpulimab in patients with recurrent/metastatic nasopharyngeal carcinoma.

This study is divided into two parts. The first part includes the safe introduction phase and the expansion phase. The second part is a randomized controlled study design, which is divided into two groups. The two parts of research are carried out at the same time

Detailed description: This study is divided into two parts:

The first part includes the safe introduction phase and the expansion phase. All the patients with advanced nasopharyngeal carcinoma who failed to be treated with platinum chemotherapy and immunocheckpoint inhibitors (anti-PD-1 monoclonal antibody/anti-PD-L1 monoclonal antibody, etc.) were enrolled. The treatment scheme is TQB2618 + Penpulimab Injection. During the safe introduction period, we explored whether the two dose groups (1200mg/1500mg) were safe and tolerable when TQB2618 was combined with Penpulimab Injection. If the two dose groups are tolerable, 18\~24 patients in the second phase of the extended study were randomized to receive TQB2618 in two dose groups (1200mg/1500mg)+Penpulimab Injection (200mg) at a ratio of 1:1. If high dose (1500mg) of TQB2618 is not tolerated, all patients will receive TQB2618 (1200mg)+Penpulimab Injection (200mg).

The second part is a randomized controlled study design, which is divided into two groups. All the newly treated patients with advanced nasopharyngeal carcinoma who have not received systematic treatment in the past received TQB2618+Penpulimab Injection+GP chemotherapy and paianzulimab+GP chemotherapy respectively. The dose of TQB2618 was 1200mg.

The two parts of research are carried out at the same time.

Eligibility criteria: Inclusion Criteria:

* Histologically or cytologically confirmed nasopharyngeal carcinoma, stage IVb as defined by the AJCC TNM staging system for nasopharyngeal carcinoma, 8th edition in 2017 or subjects with recurrent nasopharyngeal carcinoma who were not suitable for local therapy (For neoadjuvant/adjuvant therapy and radical concurrent chemoradiotherapy, if the disease progresses during treatment or within 6 months after the treatment completion, it should be counted as a failure of first-line treatment of the original plan, and if it exceeds 6 months, it cannot be counted as first-line treatment failure. Alterations of treatment regimen due to drug intolerance are not defined as treatment failure).
* The first part of enrolled patients shall also meet the following requirements:

  1. At least received first-line treatment for recurrent/metastatic lesions, and the last anti-tumor treatment before enrollment had evidence of imaging progress in line with RECIST 1.1 standard;
  2. At least have received platinum containing chemotherapy and immunocheckpoint inhibitors (anti-PD-1 monoclonal antibody/anti-PD-L1 monoclonal antibody, etc.) in the past and failed treatment, and there is evidence of imaging progress that meets the RECIST 1.1 standard. Platinum containing chemotherapy and immunotherapy can be used during palliative treatment for recurrent/metastatic lesions, or during radical treatment for locally advanced diseases.
  3. Immunotherapy for recurrent/metastatic lesions shall not exceed 2 lines (For neoadjuvant/adjuvant therapy and radical concurrent chemoradiotherapy, if the disease progresses during treatment or within 6 months after the treatment completion, it should be counted as a failure of first-line treatment of the original plan, and if it exceeds 6 months, it cannot be counted as first-line treatment. Failure. Alterations of treatment regimen due to drug intolerance do not defined as treatment failure
  4. For the latest immunotherapy before enrollment, if it is aimed at recurrence/metastasis, the best efficacy is at least SD (≥ 6 weeks) or confirmed PR or immunotherapy duration ≥ 12 weeks.
* The second part of the enrolled patients also need to meet the following requirements:

  1. Have not received systemic antitumor therapy for recurrent/metastatic nasopharyngeal carcinoma before;
  2. No previous treatment with immune checkpoint inhibitors (anti PD-1 monoclonal antibody/anti PD-L1 monoclonal antibody, etc.). Those who have used no more than one immune checkpoint inhibitor (limited to CTLA-4/PD-1/PD-L1 monoclonal antibody, not including bispecific antibody, not including Penpulimab injection) in the stage of locally advanced radical treatment can be included if they meet the following criteria:

     1. If used in the induction phase (with or without other drugs), the best effect in the induction phase is at least PR;
     2. If used during radical radiochemotherapy/radiotherapy or subsequent maintenance stage, there is no progress during treatment and within one year after stopping treatment
* At least one measurable lesion confirmed according to RECIST 1.1 criteria;
* The function of main organs are well and meet the following standards:

  1. Routine Blood routine examination standards (without blood transfusion or correction with hematopoietic stimulating factor drugs within 14 days before the examination):

     1. Hemoglobin (HGB) ≥90 g/L;
     2. Absolute value of neutrophil (NEUT) ≥1.5×109/L;
     3. Platelets count (PLT) ≥ 100×109/L.
  2. The biochemical examination shall meet the following standards:
