B.S. Bhati: Cracking the Brain Barrier – Lazertinib vs Osimertinib in EGFR+ NSCLC

B.S. Bhati, Medical Oncologist at AIIMS New Delhi, shared a post on X about a paper by James CH Yang et al. published in Clinical Lung Cancer:

“Cracking the Brain Barrier: Lazertinib vs Osimertinib in EGFR+ NSCLC

CNS Outcomes in EGFR+ NSCLC

Lazertinib (LASER201/301):
  • iORR 92%
  • iPFS 27.7 mo
  • iDoR 26.5 mo
Osimertinib (FLAURA):
  • iORR 91% vs 68%
  • iPFS NR vs 13.9 mo (HR 0.48)
  • iDoR ~15.2 mo
Osimertinib+Chemo (FLAURA2):
  • iORR ~89% vs ~82%
  • 12-mo CNS PFS 89% vs 82%
  • DCR >95%

Both lazertinib and osimertinib show strong CNS efficacy

FLAURA2 combo maintains CNS protection and boosts systemic PFS.”
