Exclusion Criteria:

• Patients who are allergic to analogue of SCT200 and/or its inactive ingredients;
• Patients with active central nervous system metastasis or a history of central nervous system metastasis;(If the subject has been suspected with central nervous system metastasis,imaging examination confirmation must be performed within 28 days to exclude central nervous system metastasis;
• Subject receiving bisphosphonate or denosumab treatment for bone metastases was initiated within 28 days prior to study. (If the subject has received bisphosphonate or denosumab treatment prior to study and showing stable time at least 28 days,the subject will be allowed to use it.) Subjects who were enrolled in this study may start taking bisphosphonate or denosumab for bone metastases after the first assessment of the efficacy.

• Patients administrated EGFR target treatment including EGFR TKI agent or anti- EGFR monoclonal antibody;
• Within 4 weeks, patients received anti-tumor drugs (such as chemotherapy, hormone therapy, immune therapy, the antibody therapy, radiotherapy) or research drugs, or patients with grade 2 or more adverse reaction caused by previous anti-tumor therapy(except alopecia or neurotoxicity grade 2 or less);
• Patients are currently enrolled in other research devices or in research drugs, or less than 4 weeks from other research drugs or devices.
• Prior to the first dose of study drug, patients received major surgery requiring general anesthesia has been completed less than 4 weeks; surgery requiring local anesthesia/epidural anesthesia has been completed less than 72 hours; skin biopsy requiring local anesthesia has been completed less than 1 hour.

• Patients with medical or psychiatric condition or laboratory abnormality may interfere with the interpretation of study results;
• Pregnant or lactating women, or women who planned to be pregnant within 6 months of treatment;
• Patients who were not willing to accept effective contraceptive measures (including male or female subjects) during treatment and for at least 6 months after your last dose of SCT200;

• Patients with uncontrolled active infections within 2 weeks before enrollment (except urinary tract infection or upper respiratory tract infection);
• Patients have alcohol or drug addiction;
• Subjects who are considered unsuitable for participating in this study for various reasons at the discretion of the investigator，such as inability to comply with study and/or follow-up procedures.
