Excerpt:
The overall response rate was 44.1%, and disease control rate was 85.3%. Progression-free survival was 7.69 months (95% CI 4.4 - NA). Based on the mutation subtype, the response rate was as follows: G719X (n=13, 53.8%), L861Q (n=11, 54.6%)...In this study, we observed the clinical benefit of 240mg Lazertinib in the treatment of naïve EGFR uncommon mutants. Among the mutations, G719X and L861Q showed promising outcomes, which are aligned with preclinical data.
