Harboring EGFR 20ins mutation, Without prior systemic therapy
Brief summary
This is a multicenter, randomized, open-label, parallel-controlled phase 3 study. This study aims to evaluate the efficacy and safety of JMT101 combined with Osimertinib compared with Cisplatin combined with pemetrexed in participants with local advanced or metastatic non-small-cell lung cancer harboured EGFR 20ins mutation without prior systemic therapy. Primary objective of this study is to assess the efficacy of JMT101 combined with Osimertinib versus Cisplatin combined with pemetrexed using by (Independent Review Center)IRC-assessed Progression Free Survival (PFS) per RECIST 1.1 as primary endpoint. Approximately 398 participants are estimated to be randomized into the study. Participants enrolled will be randomized to JMT101 or Cisplatin chemotherapy in a 1:1 manner, stratified by baseline brain metastasis (with/without) and Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) (0 versus 1).
Interventions
JMT101 Injection, 6 mg/kg intravenously, over 90 mins every 14 days
Osimertinib 160mg once po everyday
Cisplatin 75mg/m\^2, IV infusion, on day-1 at every cycle of 21days, 4 cycles at most.
Pemetrexed 500mg/m\^2, IV infusion, on day-1 at every cycle of 21 days.
