Firmonertinib Versus Platinum Based Chemotherapy as First-line Treatment for NSCLC With EGFR PACC or EGFR l861q Mutation

Официальное название

A Phase III, Randomized, Multicentre, Open Label Study to Assess the Efficacy and Safety of Firmonertinib Versus Platinum Based Chemotherapy as First-line Treatment for Locally Advanced or Metastatic Non-small Cell Lung Cancer Patients With EGFR PACC Mutation or EGFR l861q Mutation

Обзор

This study is a randomized, open, multicenter phase III clinical study, which aims to evaluate the efficacy and safety of firmonertinib mesylate compared with platinum based chemotherapy for patients with locally advanced or metastatic NSCLC who have not been treated with systemic antitumor therapy and carry EGFR PaCC mutation or EGFR l861q mutation. Eligible patients were stratified by EGFR mutation type and CNS metastasis at the time of enrollment. Approximately 300 patients would be randomly assigned 1:1 to receive either firmonertinib mesylate (240mg, orally on an empty stomach daily) or platinum containing dual agent chemotherapy.
