What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 45 participants in total. It began in 2026-07-03 with a primary completion date of 2027-12-03.

Brief Summary

This is a single-arm, exploratory phase Ib/II study with a seamless design to evaluate the safety and efficacy of Vebreltinib combined with furmonertinib as first-line treatment in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) harboring EGFR-sensitive mutations (exon 19 deletion or L858R) and PD-L1 TPS ≥50%. In the phase Ib part, 12-16 patients will be enrolled to compare the safety and early efficacy of Vebreltinib 100mg BID versus 150mg BID in combination with furmonertinib 80mg QD, and to determine the recommended phase II dose (RP2D). In the phase II part, 37 patients (including evaluable patients from the RP2D cohort in phase Ib) will receive treatment at the RP2D. The primary endpoint is investigator-assessed median progression-free survival (PFS). Secondary endpoints include objective response rate (ORR), disease control rate (DCR), overall survival (OS), and safety. Exploratory endpoints will analyze the correlation between baseline MET abnormalities and treatment efficacy.
