Summary: This was a multicenter, open-label phase 2 study. This study aimed to evaluate the efficacy and safety of JMT101 combined with Osimertinib in participants with local advanced or metastatic non-small-cell lung cancer harbouring EGFR common mutation with or without prior systemic therapy. Efficacy indexes included investigator-assessed Overall Response Rate(ORR), Disease Control Rate(DCR), Duration of Response( DoR), Progression Free Survival (PFS) per RECIST 1.1 and Overall Survival (OS). Safety indexes included Adverse Events incidence and severity. This study included 4 cohorts, cohort 1 included EGFR-mutated advanced NSCLC patients without prior systemic therapy and accepted JMT101 6mg/Kg Q3W and Osimertinib 80mg QD therapy. Cohort 2 included EGFR-mutated advanced NSCLC patients who failed with prior generation 1 or 2 EGFR-TKIs therapy and accepted JMT101 6mg/Kg Q2W and Osimertinib 80mg QD therapy. Cohort 3 included advanced EGFR common mutation NSCLC patients who failed with prior generation 3 EGFR-TKIs but did not accept chemotherapy and accepted JMT101 6mg/Kg Q2W and Osimertinib 80mg or 160mg QD therapy. Cohort 4 included EGFR-mutated advanced EGFR NSCLC patients who failed with prior generation 3 EGFR-TKIs and platinum-based chemotherapy and accepted JMT101 6mg/Kg Q2W and Osimertinib 80mg or 160mg QD therapy.

At least 1 measurable lesion per RECIST Version 1.1. 4. Life expectancy ≥ 12 weeks. 5. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1. 6. Adequate organ and hematologic function 7. Women with fertility tested negative for blood pregnancy within 7 days prior to trial screening; Any male or female patients with fertility must agree to use effective contraceptive methods throughout the entire trial period and within six months after the end of the trial. 8. Patients must give informed consent to this study before the trial and voluntarily sign a written informed consent form. Exclusion Criteria: 1. Previously received EGFR monoclonal antibody therapy. 2. Have received anti-tumor treatments such as chemotherapy, biological therapy, targeted therapy, immunotherapy, etc. within 4 weeks prior to the first use of the study drug. 3. Have undergone major organ surgery (excluding biopsy) or experienced significant trauma within 4 weeks prior to the first use of the study drug. 4. Have received other clinical study drugs within 4 weeks prior to the first use of the study drug. 5. Known hypersensitivity or intolerance to any component of the study drug or its excipients. 6.
