Evidence of active infections, including Hepatitis B, Hepatitis C or human immunodeficiency virus (HIV) infection.
Active bacterial, viral, fungal, rickettsial, or parasitic infection requiring systemic therapy.
Prior history of other primary malignancies.
History of the following ophthalmologic abnormalities: severve dry eye syndrome; keratoconjunctivitis sicca; severe exposure keratitis; any other condition that may increase the risk of corneal epithelial damage.
History of severe skin disease requiring interruption of previous EGFR targeted therapy; or chronic skin disease requiring oral or intravenous therapy.
History of interstitial lung disease (ILD) or pneumonitis, severe chronic obstructive pulmonary disease, severe pulmonary insufficiency, symptomatic bronchospasm, etc.
Pulmonary radiotherapy > 30 Gy within 6 months prior to first dose of study drug.
Pulmonary embolism or deep vein thrombosis within 3 months prior to the first dose of study drug.

History of allogeneic tissue or solid organ transplant.
Female patients with a positive serum pregnancy test or who are breast feeding or do not agree to take adequate contraceptive measures during the treatment and for 6 months after the last dose of study treatment.
Active uncontrolled concomitant diseases that might limit patient's compliance with study requirements, or compromise patient's ability to provide written informed consent.
Other conditions inappropriate for participation in this clinical trial, at the discretion of the investigator.

Arm && Interventions

Group	Intervention	Description
MRG003	MRG003	On the first day of every 3 weeks, MRG003 will be administered via intravenous infusion at 2.0 mg/kg calculated based on the actual body weight

Primary Outcome Measures

Name	Time	Method
Objective Response Rate (ORR) by Investigator	Baseline to study completion, up to 12 months	ORR is defined as the proportions of patients with a complete response (CR) and partial response (PR). ORR will be assessed by investigator according to RECIST v1.1.

Secondary Outcome Measures

Name	Time	Method
Duration of Response (DoR)	Baseline to study completion, up to 12 months	DOR is defined as the duration from the initial recording of objective disease response to the first onset of tumor progression, or death of any cause.
Progression Free Survival (PFS)	Baseline to study completion, up to 12 months	PFS is defined as the duration from the start of treatment to the onset of tumor progression or death of any cause.
Time to Response (TTR)	Baseline to study completion, up to 12 months	TTR is defined as the duration from the start of treatment to the first onset of CR or PR in tumor evaluation.
Overall Survival (OS)	Baseline to study completion, up to 12 months	OS is defined as the duration from the start of treatment to death of any cause.
Disease Control Rate (DCR)	Baseline to study completion, up to 12 months	DCR is defined as the proportions of patients achieving CR, PR, and stable disease (SD) after treatment.
Adverse Events (AEs)	Baseline to 60 days after the last dose of study treatment	Any reaction, side effect, or untoward event that occurs during the course of the clinical trial whether or not the event is considered related to the study drug.
