TAGRISSO: Designed to potently and selectively inhibit EGFR sensitising and resistance mutations1,2

TAGRISSO is a third-generation, irreversible EGFR TKI designed to1,2:

  • Inhibit EGFR sensitising mutations (EGFRm, commonly exon 19 deletion and L858R)1,2*
  • Inhibit the emergence of the EGFR T790M resistance mutation2,3
  • Have minimal activity against wild-type EGFR1*
Potently inhibits both EGFRm and EGFR T790M1-3*
Potently† inhibits both EGFRm and EGFR T790M1-3
Minimal activity against wild-type EGFR1*
Minimal activity against wild-type EGFR1,2
Potently† inhibits both EGFRm and EGFR T790M1-3
In addition, TAGRISSO crosses the intact blood-brain barrier4
