Exclusion Criteria:

• Patients who were allergic to analogue of SCT-I10A/SCT200 and/or its inactive ingredients, Patients who were allergic to Capecitabine and/or Oxaliplatin were also excluded in cohort3;

• Patients have been treated with anti-PD-L1/PD-L2 or anti-PD-1, EGFR antibody or EGFR-TKI;

• Within 4 weeks prior to the first dose of study drug, patients have received anti-tumor drugs (such as chemotherapy, endocrine therapy, targeted therapy, immune therapy, tumor embolization). Within 6 weeks prior to the first dose of study drug, patients have been treated with biological products, nitrosourea or mitomycin C. Within 4 weeks prior to the first dose of study drug, patients have been treated with tumor embolization or radiotherapy;

• Within 2 weeks prior to the first dose of study drug, patients have received corticosteroids or other immunosuppressive agents;

• Within 1 month prior to the first dose of study drug, patients have received live attenuated vaccine (LAV);

• Patients are currently enrolled in other research devices or in research drugs, or less than 4 weeks from other research drugs or devices;

• Patients with significant malnutrition. Patients will be excluded if they are receiving intravenous hyperalimentation, or require continuous infusion therapy with hospitalization. Patients whose nutrition has been well controlled for = 28 days prior to randomization may be enrolled.

• Within 4 weeks prior to the first dose of study drug, patients have received major surgery, or had wounds, ulcers or fractures that haven't healed; Within 6 weeks prior to the first dose of study drug, patients were suffering with gastrointestinal perforation or fistula;

• Has active infection or fever of unknown origin(> 38.5?);

• Active central nervous system (CNS) metastases and/or carcinomatous meningitis; subjects with previous treated brain metastases may participate provided they are stable for at least 2 weeks prior to the first dose of study medication, have no evidence of new or enlarging brain metastases, and are not using steroids for at least 14 days prior to trial treatment. Subjects with asymptomatic brain metastases (without neurological symptoms, not using steroids, tumor lesions=1.5cm) may participate in condition that the tumor lesion should be regularly evaluated using identical imaging modality for each assessment, either MRI or CT scans;

• Patients with clinical symptoms, required clinical intervention or stable time less than 4 weeks of serous cavity effusion (such as pleural effusion and ascites);

• Poorly controlled hypetension. Within 6 months prior to study, patients had uncontrolled concurrent diseases, including but not limited to acute myocardial infarction, unstable angina pectoris, stroke, or transient ischemic attack, congestive heart failure (NYHA, greater than II), left ventricular ejection fraction (LVEF) <50%, and with related heart disease.

• Patients who have interstitial lung disease or imaging features of interstitial pneumonia, or who have history of non-infectious pneumonia treated with corticosteroids.

• Patients with an active, known or suspected autoimmune disease or a history of autoimmune disease;

• Within 5 year prior to the first dose of study drug, patients have other primary malignancies;

• Have a history of HIV;

• Patients with a history of allogeneic organ transplantation or allogeneic hematopoietic stem cell transplantation;

• Has known active Hepatitis B (e.g. HBsAg reactive) or Hepatitis C(e.g. HCV RNA [quantitative] is detected);

• Prior to the first dose of study drug, patients had toxicity due to previous anti-tumor treatment, which hasn't return to Grade 0-1 according to the NCI CTCAE v5.0;

• Has known with alcohol or drug addiction;

• Pregnant or lactating women;

• Patients who were not willing to accept effective contraceptive measures during treatment and within 6 months after treatment;

• Subjects who are considered not suitable for the study by investigator
