JS212 in Combination With JS111 as First-Line Treatment in EGFR-Mutant Advanced NSCLC

This is a single-arm clinical study evaluating the safety, tolerability, and preliminary efficacy of JS212 in combination with JS111 as first-line treatment in participants with epidermal growth factor receptor (EGFR)-mutant locally advanced or metastatic non-small cell lung cancer (NSCLC) who have not received prior systemic therapy for advanced disease. The study consists of a safety lead-in stage followed by a clinical expansion stage. Approximately 20 participants are planned to be enrolled across the two stages. Participants will receive JS212 by intravenous infusion on Day 1 of each 21-day cycle and JS111 at 160 mg orally once daily until treatment discontinuation criteria are met. During the safety lead-in stage, up to 10 participants will be enrolled and monitored for significant toxicities during the first 21 days after initial administration. The Safety Monitoring Committee (SMC) will review available safety, tolerability, and efficacy data and determine the JS212 dose to be further evaluated, whether an additional higher or lower dose should be explored, and whether the study may proceed to the clinical expansion stage.
