Title:
Possibility of brigatinib-based therapy, or chemotherapy plus anti-angiogenic treatment after resistance of osimertinib harboring EGFR T790M-cis-C797S mutations in lung adenocarcinoma patients

Excerpt:
Patients carrying EGFR exon 19 deletion mutation had a longer PFS than those who harboring EGFR exon 21 p.L858R mutation (4.57 vs. 1.03 months, HR = 0.18, 95% CI: 0.06-0.54, p = 0.001), no matter they received brigatinib-based therapy (mPFS: 5.00 vs. 3.23 months, HR = 0.19, 95% CI: 0.01-0.96, p = 0.05) or chemotherapy-based treatment (mPFS: 7.23 vs. 1.03 months, HR = 0.05, 95% CI 0.01-0.49, p < 0.001)....Brigatinib-based therapy and chemotherapy plus anti-angiogenics could be considered beyond progression from osimertinib therapy. For patients harboring EGFR exon 19 deletion/T790M/cis-C797S mutation, the clinical efficacy was superior to patients harboring EGFR exon 21 p.L858R/T790M/cis-C797S mutation.
