2. Age: 18-75 years old;
3. No gender limit;
4. Esophageal squamous cell carcinoma diagnosed by pathology;
5. The results of 3-gene RNA sequencing (ALTRK) in tumor tissue were negative;
6. Imagingly confirmed unresectable advanced esophageal squamous cell carcinoma;
7. Failure of previous platinum-containing regimens and immunotherapy regimens (PD-1/PD-L1 monoclonal antibody);
8. At least one measurable lesion (according to RECIST1.1 criteria) or non-measurable lesion that can be evaluated, with imaging diagnosis ≤ 21 days from enrollment;

4. Those who have received radiotherapy for measurable lesions;
5. Previous anti-EGFR monoclonal antibody or EGFR-TKI treatment;
6. Patients with other primary malignant tumors other than esophageal cancer at the same time, except for cured skin basal cell carcinoma and cervical carcinoma in situ;
7. Clinically significant cardiovascular diseases, such as heart failure (NYHA GRADE III-IV), uncontrolled coronary heart disease, cardiomyopathy, arrhythmia, uncontrolled hypertension or history of myocardial infarction within the past 1 year;
8. Neurological or psychiatric abnormalities affecting cognitive ability, including central nervous system metastases;
9. Active severe clinical infection (grade >2 NCI-CTCAE version 5.0) within 14 days prior to enrollment, including active TB;
10. Known or reported HIV infection or active hepatitis B or C;
11. Uncontrolled systemic diseases, such as poorly controlled diabetes;
12. History of interstitial lung disease, such as interstitial pneumonia, pulmonary fibrosis, or evidence of interstitial lung disease on baseline chest x-ray/CT;
