Red Flag Origin

Definition	BRAF V600E mutation in NSCLC adenocarcinoma — ~1-2% prevalence. Dabrafenib + trametinib (BRF113928 — ORR 64% 1L, 63% 2L+) is the approved targeted regimen; encorafenib + binimetinib (PHAROS) is newer alternative. Non-V600 BRAF mutations are not actionable with these doublets.

Notes

Smoker-associated unlike most NSCLC drivers. Pyrexia is the dominant on-target tox of BRAF+MEK doublets — patient education + dose-hold algorithm essential. MEK-inhibitor LVEF monitoring (baseline + q3-monthly echo). PD-L1 status irrelevant when BRAF V600E + TKI-doublet chosen.
