About

Previous clinical studies showed there is a potential value of EGFR-TKI in local advanced EGFR-mutant NSCLC, while the risk of radiation pneumonia in combination of EGFR-TKI with thoracic radiotherapy is unknown. This study aims to explore the safety and efficacy of concurrent almonertinib, a new third-generation EGFR-TKI drug, with radiotherapy in local advanced EGFR-mutant NSCLC patients.

Full description

Doublet platinum-based therapy combined with radiotherapy remains the standard treatment for first-line management of unresectable stage III NSCLC patients, regardless of the EGFR mutation status. But the 5-year survival rate is not satisfying. Previous clinical studies showed there is a potential value but also a high risk of radiation pneumonia in treatment regimens of combination TKI with radiotherapy. This study intends to explore the safety and efficacy of concurrent almonertinib, a new third-generation EGFR-TKI drug, with radiotherapy in EGFR-sensitive mutated locally advanced NSCLC patients.
