Eligibility criteria: Inclusion Criteria:

* 1. age 18-75, male or female;
* 2. patients with advanced (inoperable stage iiiib -IV) primary pulmonary lymphoepithelioid carcinoma diagnosed pathologically, with at least one measurable lesion meeting RECIST v1.1 criteria;
* 3. patients have not received systemic therapy before (patients who have received platinum-containing adjuvant chemotherapy, neoadjuvant chemotherapy or radical chemoradiotherapy for advanced disease can enter if the disease progression occurs 6 months after the end of the last treatment);
* 4. ECOG PS: 0-1; expected survival ≥12 weeks;
* 5. vital organ functions meet the following requirements (excluding the use of any blood components or cytokines during screening) :The absolute count of neutrophils ≥1.5×109/L;Platelet ≥90×109/L;Hemoglobin ≥9g/dL;Serum albumin ≥3g/dL;Thyroid stimulating hormone (TSH) ≤ULN (if abnormal, T3 and T4 levels should be examined at the same time; if T3 and T4 levels are normal, they can be included in the group);Bilirubin ≤ULN;ALT and AST≤1.5 ULN;AKP 2.5 x ULN or less;Serum creatinine ≤1.5 ULN or creatinine clearance ≥60mL/min;
* 6. women of childbearing age must have been using reliable contraception or have had a pregnancy test (serum or urine) within 7 days prior to enrollment and have had negative results and be willing to use appropriate methods of contraception during the trial and 8 weeks after the last administration of the trial drug. For men, consent must be given to appropriate methods of contraception or surgical sterilization during the trial and 8 weeks after the last administration of the trial drug;
* 7. subjects voluntarily participate in this study and sign informed consent, with good compliance and follow up.

Exclusion Criteria:

* 1. those who have used other drugs to study drugs in clinical trials within 4 weeks before the first drug use;
* 2. the presence of any active autoimmune diseases or a history of autoimmune diseases (as follows, but not limited to: autoimmune hepatitis, interstitial pneumonia, uveitis, enteritis, hepatitis, hypophysitis, vasculitis, nephritis, hyperthyroidism, or decreased thyroid function; Subjects with vitiligo or with complete remission of asthma in childhood were included without any intervention in adulthood. Subjects with asthma requiring medical intervention with bronchodilators were not included.
* 3. subjects who are using immunosuppressive agents, or systemic, or absorbable local hormone therapy for immunosuppressive purposes (dose \>10mg/ day prednisone or other therapeutic hormones) and continue to use within 2 weeks prior to enrollment;
* 4. severe allergic reaction to monoclonal antibody;
* 5. subjects with clinically symptomatic CNS metastases (e.g. cerebral edema, need for hormone intervention, or progression of brain metastases). Patients who have received previous treatment for brain or meningeal metastasis, such as clinical stability (MRI) has been maintained for at least 2 months, and who have stopped systemic sex hormone therapy (dose \>10mg/ day prednisone or other therapeutic hormones) for more than 2 weeks can be included.
* 6. subjects have heart clinical symptoms or diseases that are not well controlled, such as: a. NYHA grade 2 or above heart failure; B. unstable angina pectoris; C. Had myocardial infarction within 1 year; D. Supraventricular or ventricular arrhythmias of clinical significance require treatment or intervention;
* 7. subjects who have previously received radiotherapy, chemotherapy, hormone therapy, surgery or molecular targeted therapy, and who have received less than 4 weeks before the study (or 5 drug half-lives, with the selected time) after the completion of the treatment (the last medication); Adverse events caused by previous treatment (except hair loss) did not recover to ≤ 1 degree CTCAE;
* 8. subjects with congenital or acquired immune deficiency (such as HIV infection) or active hepatitis (hepatitis b reference: HBsAg positive, HBV DNA≥2000 IU/ml or copy number ≥104/ml; Hepatitis c reference: positive HCV antibody;
* 9. subjects with active infection or unexplained fever \>38.5 degrees during screening or before first administration;
* 10. subjects with congenital or acquired immune deficiency (such as HIV infection) or active hepatitis (hepatitis b reference: HBsAg positive, HBV DNA≥2000 IU/ml or copy number ≥104/ml; Hepatitis c reference: positive HCV antibody;
* 11. other malignancies (except cured basal cell carcinoma of the skin and carcinoma in situ of the cervix of the cervix) that the subjects had had or had at the same time;
* 12. according to the researcher's judgment, the subjects have other factors that may lead to the forced termination of this study, such as other serious diseases (including mental diseases) requiring combined treatment, severe laboratory examination abnormalities, accompanied by family or social factors, which may affect the safety of the subjects, or the collection of data and samples.
