*Secondary endpoint in FLAURA. Primary endpoint was PFS: 18.9 months median PFS (95% CI: 15.2, 21.4) with first-line TAGRISSO vs 10.2 months median PFS (95% CI: 9.6, 11.1) with erlotinib/gefitinib (HR=0.46 [95% CI: 0.37, 0.57]; P<0.0001).1

Crossover to TAGRISSO was allowed for patients receiving erlotinib/gefitinib at confirmed progression if positive for the EGFR T790M resistance mutation. 65% (n=180) of patients in the erlotinib/gefitinib arm received any second-line therapy, of whom 47% (n=85) crossed over to TAGRISSO.2,5

  • CNS PFS results only take into account progression in the CNS. To provide strong control for the type I error rate, the primary endpoint of PFS and endpoints of OS and CNS PFS were tested sequentially8

*Based on a meta-analysis that examined the incidence of brain metastases in EGFRm or EGFR wild-type NSCLC. 8152 patients were included from 22 multinational studies. 16 studies included patients with stage IV disease. 2664 patients had an EGFR mutation.6

Based on a retrospective US study that evaluated the frequency of brain metastases in 381 patients with advanced NSCLC. 86 of those patients had an EGFR mutation.7

IIBased on confirmed response.

Based on investigator assessment.

#Progression events that do not occur within 2 scheduled visits of the last evaluable assessment, or randomization, are censored and therefore excluded in the number of events (excluding deaths).9

**PET brain imaging studies in healthy volunteers and in patients with brain metastases show that TAGRISSO is distributed to the brain following intravenous injection of a microdose of 11C-labeled osimertinib.1
