This is an interventional treatment trial for Esophageal Squamous Cell Carcinoma Read More

Inclusion Criteria:

1. 18~75 years, both men and women.

3. Patients undergoing first-line systemic chemotherapy (which may include platinum, lavender or fluorouracil) progression or intolerance (progress in maintenance therapy after first-line chemotherapy can also be included). Synchronous chemoradiotherapy for postoperative recurrence or metastasis is considered as first-line treatment; For radical concurrent chemoradiotherapy, neoadjuvant/adjuvant therapy (chemotherapy or chemoradiotherapy), if disease progression occurs during treatment or within 6 months after stopping treatment, Count it as a first-line treatment failure.
4. At least one measurable/evaluable lesion by RECIST v1.1. And the measurable lesions should not have received local treatment such as radiotherapy (The lesion located in the previous radiotherapy area, if confirmed to progress, and meets the RECIST 1.1 standard, can also be used as a target lesion).
5. EGFR immunohistochemistry or FISH detection was positive in tumor tissue samples.
6. Tissue samples shall be provided for biomarker analysis, preferably newly acquired tissues, and patients who are unable to provide newly acquired tissues may provide 5-8 pieces of 5um thick paraffin sections that are archived and preserved.
7. Eastern Cooperative Oncology Group(ECOG) performance status 0 or 1.
8. Life expectancy of ≥ 12 weeks.
9. The main organs function normally, that is, the following criteria are met:

(1) Blood routine examination:

1. HB≥90g/L;
2. ANC ≥ 1.5 × 109 / L;
3. PLT ≥ 80 × 109 / L. (2) Biochemical examination:

a. ALB ≥ 30g / L; b. ALT and AST ≤ 2.5ULN; if there is liver metastasis, ALT and AST ≤ 5ULN; c. TBIL ≤ 1.5ULN; d. plasma Cr ≤ 1.5ULN or creatinine clearance (CCr) ≥ 60ml / min. 10. Doppler ultrasound assessment: left ventricular ejection fraction (LVEF)≥ normal low limit (50%).

11. Women of childbearing age should agree to use contraceptives (such as intrauterine devices, contraceptives or condoms) during the study period and within 6 months of the end of the study; the serum or urine pregnancy test is negative within 7 days prior to study enrollment, and Must be non-lactating; males should agree to use contraceptives during the study period and within 6 months of the end of the study period.

12. Subjects voluntarily joined the study, signed informed consent, and were well-adhered to follow-u.

Exclusion Criteria:

1. The patient has any active autoimmune disease or a history of autoimmune disease (such as the following, but not limited to: autoimmune hepatitis, interstitial pneumonia, uveitis, enteritis, hepatitis, pituitary inflammation, vasculitis, nephritis, thyroid Hyperfunction; patients with vitiligo; complete remission of asthma in childhood, can be included without any intervention after adult; asthma patients who require bronchodilators for medical intervention cannot be included).
2. The patient is using immunosuppressive agents or systemic hormonal therapy for immunosuppression purposes (dose >10 mg/day of prednisone or other therapeutic hormones) and continues to be used within 2 weeks prior to enrollment.
3. Patients who received EGFR monoclonal antibody or EGFR tyrosine kinase inhibitor;
4. Patients who received other PD-1 antibody therapy or other immunotherapy against PD-1/PD-L1;
5. Patients with brain metastases with symptoms or symptom control for less than 3 months;
6. Patients with any severe and/or uncontrolled diseases, including patients with unsatisfactory blood pressure control (systolic blood pressure ≥150 mmHg or diastolic blood pressure ≥100 mmHg); patients with grade I or higher myocardial ischemia or myocardial infarction, arrhythmia (including QT interval ≥ 480ms) and grade I cardiac insufficiency; active or uncontrolled severe infection; liver disease such as decompensated liver disease, active hepatitis B (HBV-DNA ≥ 104 copy number / ml or 2000 IU / ml) Or hepatitis C (positive hepatitis C antibody, and HCV-RNA is higher than the lower limit of detection of the analytical method);
7. Imaging studies have shown that the tumor has invaded the important vascular circumference or that the patient is likely to invade the important;
8. Pregnant or lactating women.
9. Patients with other malignant tumors within 5 years（Except for skin basal cell carcinoma and cervical carcinoma in situ that have been cured).
10. Patients with a history of psychotropic substance abuse who are unable to quit or have a mental disorder.
11. Patients who have participated in other drug clinical trials within four weeks.
12. According to the investigator's judgment, the patients with concomitant diseases that seriously endanger the safety of the patient or affect the patient's completion of the study.
13. Researchers believe that it is not suitable for inclusion. -
