• Renal function: creatinine (Cr) ≤ normal upper limit × 1.5;
• Electrolyte: Magnesium ≥ normal lower limit;
• According to the RECIST standard version 1.1, there is at least one measurable tumor lesion.

Exclusion Criteria:

• Patients with a history of central nervous system metastasis or a history of central nervous system metastasis before screening. For patients with clinically suspected central nervous system metastasis, imaging confirmation must be performed within 28 days prior to enrollment to exclude central nervous system metastasis;
• Received systemic chemotherapy for advanced or metastatic HNSCC, but do not include induction chemotherapy, concurrent chemoradiotherapy or adjuvant chemotherapy (the end of this treatment must be more than 6 months from the first trial);
• There are other medical history of malignant tumors, except that the malignant lesions have been treated with therapeutic measures 5 years or more before enrollment and there are no known active lesions. The investigator judges that the risk of recurrence is low; Non-melanoma skin cancer, and no evidence of worsening disease; adequately treated cervical cancer in situ, and no evidence of worsening disease; prostatic intraepithelial neoplasia, no evidence of prostate cancer recurrence;
• known to be allergic to antibodies or other components contained in the test drug;
• have received EGFR antibodies (such as panitumumab, cetuximab or its analogs), or small molecule EGFR inhibitors (such as gefitinib, erlotinib, lapatinib, etc.);
• In the 4 weeks or 4 weeks before enrollment, they received anti-tumor drugs (such as chemotherapy, hormone therapy, immunotherapy, antibody therapy, radiotherapy, etc.) or received research drug treatment and could not be included in the evaluation by the investigator. Pain-free palliative radiotherapy for bones;
• At the time of enrollment, patients still had ≥2 peripheral neuropathy or hearing loss;
• Patients have been enrolled in other study devices or study drug studies at screening time, or have been deactivated for less than or equal to 4 weeks from other study drugs or study devices;
• Conduct or plan major surgery within 4 weeks prior to enrollment;
• Received transfusion, erythropoietin (EPO), granulocyte colony-stimulating factor (G-CSF) or granulocyte-macrophage colony-stimulating factor (GMCSF) within 2 weeks prior to enrollment;

• Clinically significant cardiovascular disease (defined as: unstable angina, symptomatic congestive heart failure (New York Heart Association [NYHA]

  ≥ II), uncontrollable severe arrhythmia);

• Myocardial infarction occurred within 6 months prior to enrollment;
• History of interstitial lung disease (ILD), such as interstitial pneumonia, pulmonary fibrosis, or evidence of ILD on baseline chest CT or MRI;
• have clinical symptoms, require clinical intervention or serous effusion (such as pleural effusion and ascites) with a stabilization time of less than 4 weeks;
• medical or psychiatric history or laboratory abnormal medical history that may interfere with the interpretation of the results;
• Patients who are pregnant or breast-feeding, or who plan to be pregnant during the treatment period and within 6 months after the end of treatment;
• Patients (including male or female patients) who are unwilling to receive effective contraception during the treatment period and within 6 months after the end of treatment;
• HCV antibody positive; or HIV positive; or HBV test results: HBsAg positive and / or HBcAb positive and HBV DNA ≥ 104 copy number or ≥ 2000 IU / ml;
• Patients have active or uncontrollable infections (except for simple urinary tract infections or upper respiratory tract infections) requiring systemic treatment within 2 weeks or 2 weeks prior to enrollment;
• known patients have alcohol or drug addiction;
• The investigator believes that patients have other conditions that may affect their adherence to protocol adherence and study indicators, and are not suitable for patients participating in the study

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Objective response rate (ORR)	ORR is defined as proportion of patients achieving complete response (CR) or partial response (PR) according to RECIST v1.1 during trial treatment.	1 year

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progresssion free survival(PFS)	PFS is defined as the time from first dose of SCT200 until the date of first documentation of progression or date of death, whichever occurs first,according to RECIST v1.1 criteria.	1 year
Immunogenicity	Serum anti-SCT200 antibody levels before and after administration	1 year
EORTC QLQ-H&N35	European organization for research and treatment of cancer quality of life questionnaire head and neck 35(EORTC QLQ-H & N 35) is a specific questionnaire developed by the European Organisation for Research and Treatment of Cancer for head and neck cancer. The module includes 35 questions Assessing symptoms and side effects of treatment, social function and body image/sexuality .This scale includes seven symptoms subscales that measure pain, swallowing, senses problems, speech problems, trouble with social eating, trouble with social Contact, and less sexuality, and also has 11 subscales related with teeth, opening mouth, dry mouth, sticky saliva, coughing, ill feeling, weight loss, weight gain, use of painkillers, nutritional supplements, and feeding tubes. Standardize the original scores, with scores ranging from 0 to 100, with higher scores representing more serious problems.	1 year
Disease control rate (DCR)	The achievement of any stable disease#SD#, partial response (PR) or complete response (CR), according to RECIST v1.1 criteria.	1 year
Overall survival(OS)	OS is defined as time from first dose of SCT200 until the date of death from any cause	1 year
EORTC QLQ-C30	Median scores for each item and domain will be reported at each time point. 30 items questionnaire with answers ranging from 1=not at all to 4=very much includes five functional scales (physical, role, emotional, cognitive and social), three symptom scales (fatigue, nausea & vomiting and pain) and a global health status/QOL scale. Furthermore, it contains six single items (dyspnea, insomnia, appetite loss, constipation, diarrhea and financial difficulties)	1 year
