PFS

Powerful efficacy demonstrated in AURA31

TAGRISSO demonstrated significantly greater efficacy vs platinum-pemetrexed in AURA3, an open-label, randomised, Phase III study in 419 patients with EGFR T790M mutation-positive advanced NSCLC who had progressed on a first-line TKI.

Median PFS was more than twice as long as with platinum-pemetrexed

PFSPFS
  • Overall survival (OS) data were not mature at the time of this initial analysis (25% mature for TAGRISSO; 29% for platinum-pemetrexed [HR=0.72; 95% CI: 0.48, 1.09; P=0.121])1

STUDY DESIGN

TAGRISSO was studied in AURA3, a Phase III randomised trial1,2

AURA3 was a Phase III, randomised, international, open-label study comparing TAGRISSO with platinum-pemetrexed in 419 patients with EGFR T790M mutation-positive NSCLC who had progressed on first-line TKI therapy.

Primary endpoint: PFS using investigator assessment according to RECIST v1.11

Secondary endpoints: ORR (investigator assessment), DoR, OS, DCR, tumour shrinkage, OS, PROs, safety and tolerability1,2

TESTING

Test for EGFR T790M at the first sign of progression

Incorporating both plasma (ctDNA) and tissue tests into your practice may identify more patients with the EGFR T790M mutation3

TESTING TESTING
  • A positive tissue or plasma EGFR T790M test indicates eligibility for TAGRISSO1
  • Response rates on TAGRISSO are similar for patients who test positive for the EGFR T790M mutation using plasma or tissue4*
  • If plasma results are negative, follow up with a tissue test wherever possible due to the potential for false negative results using a plasma-based test1
  • Only validated tests with demonstrated utility for determining EGFR T790M mutation status should be used. In AURA3, all patients were required to have EGFR T790M mutation-positive NSCLC identified by cobas® EGFR mutation test performed in a central laboratory prior to randomisation1
Ensure that your lab is prepared to detect the EGFR T790M mutation with liquid biopsy and tissue testing
