An Open-label, Multicenter , Phase II Clinical Study to Evaluate the Efficacy and Safety of HLX07 (Recombinant Humanized Anti-EGFR Monoclonal Antibody Injection) in Combination with Chemotherapy or Monotherapy in Advanced Non-squamous Non-small Cell Lung Cancer (nsqNSCLC) Patients with High EGFR Expression

Inclusion Criteria:

1. Age>=18Y
2. Good Organ Function
3. Expected survival time ≥ 3 months
4. Histologically confirmed, advanced/recurrent or metastatic nsqNSCLC
5. Measurable lesion according RECISTv1.1 by investigator
6. High EGFR expression H score ≥200
7. ECOG score 0-1

Exclusion Criteria:

1. Histologically, squamous NSCLC should be excluded. For tumors with adenocarcinoma and squamous carcinoma, if the adenoid component is dominant and the squamous component is < 5%, the patients meet the inclusion requirements.
2. Previous treatment with EGFR inhibitors
3. Symptomatic brain or meningeal metastases (unless the patient has been on > treatment for 3 months, has no evidence of progress on imaging within 4 weeks prior to initial administration, and tumor-related clinical symptoms are stable).
4. Active clinical severe infection;
5. A history of other malignancies within 5 years, except for cured carcinoma in situ of the cervix or basal cell carcinoma of the skin,etal.
