JMT101 Combined With Osimertinib in Patients With Stage Ⅲb-Ⅳ Non-small Cell Lung Cancer (NSCLC) Characterized by Epithermal Growth Factor Receptor (EGFR) Common Mutations

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.
