A Study of TY-9591 With Chemotherapy as 1st Line Treatment in Patients With Mutated Epidermal Growth Factor Receptor NSCLC

Participants were randomly assigned in a 1:1 ratio to either cohort 1 or cohort 2 for 21-day treatment cycles until disease progression (RECIST v1.1 criteria), treatment discontinuation criteria, withdrawal criteria, or study discontinuation, whichever occurred first. After the subjects terminate or withdraw from this study, the investigators can use reasonable follow-up treatment according to the subjects' condition.
