Tyrosine receptor inhibitors (TKIs) have subsequently emerged as the standard-of-care treatment for EGFR-mutant NSCLC. However, there are currently limited treatment options for TKI-refractory EGFR-mutant NSCLC. It is in this context that immunotherapy has arisen as a particularly promising player, especially in the context of favorable results from the ORIENT-31 and IMpower150 trials. Thus, the results of the CheckMate-722 trial were highly anticipated, as it was the first global trial to evaluate the efficacy of immunotherapy in addition to standard platinum-based chemotherapy, specifically in the treatment of EGFR-mutant NSCLC post-progression on TKIs.Keywords: immunotherapy, epidermal growth factor receptor mutation, osimertinib refractory |
