EGFR Uncommon Mutations

Global, Phase 3, randomized, multicenter, open-label study evaluating the efficacy and safety of firmonertinib at a dose level of 240 mg QD compared to investigator's choice of osimertinib (80 mg QD) or afatinib (40 mg QD) in participants who have locally advanced or metastatic NSCLC with EGFR PACC mutations, and who have not received any prior therapy for advanced disease. Participants will be randomized in a 1:1 ratio to treatment with firmonertinib or osimertinib or afatinib and will take the assigned dose daily.

This is a prospective, single-arm, Phase II clinical study aimed at evaluating the efficacy and safety of 160mg fimonertinib in combination with definitive radiotherapy for patients with EGFR uncommon driver mutation-positive, Stage III unresectable lung adenocarcinoma. The primary endpoint is Progression-Free Survival (PFS), assessed by the investigator according to RECIST 1.1 criteria, defined as the time from the first dose to objective disease progression or death (from any cause). Secondary endpoints include PFS by different mutation types, OS, ORR, DCR, as well as adverse events and their severity.
