A Study to Evaluate Safety and Efficacy of HS-10296 as First-Line Treatment in Patients

This is a randomized, controlled, double-blind, multicenter, phase III clinical trial, evaluating the efficacy and safety of HS-10296 compared to gefitinib in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor sensitizing mutations (EGFRm+) who have not received systemic therapy. Patients are randomly assigned to an HS-10296 treatment group or a gefitinib treatment group at a ratio of 1:1 and receive a once-daily oral dose of HS-10296 or gefitinib, in order to compare the efficacy and safety of the two different treatment regimens.
