In advanced, progressive, well-differentiated nonfunctional GI and lung NET, and advanced, progressive pNET

AFINITOR delivers a triple antitumor effect both in vitro and in vivo1,2


mTOR pathway activation is common across the NET spectrum, including GI and lung NET, and pNET

  • >70% of clinical specimens of ileal GI NET and lung NET3,4
    • mTOR pathway activation is most common in well-differentiated (G1/G2) lung NET
  • 52% to 67% of pNET5,6
    • Insulin-driven activation of the PI3K/Akt/mTOR pathway is thought to play a key role in normal pancreatic cell proliferation2


The high rate of mTOR pathway activation in NET
makes mTOR inhibition with AFINITOR
a rational approach to targeted therapy.


As an mTOR inhibitor, AFINITOR delivers a triple antitumor effect in vitro and in vivo by directly inhibiting1:

AFINITOR directly inhibits growth and proliferation, metabolism, and angiogenesis


Triple antitumor effect:

Target advanced, progressive, well-differentiated nonfunctional GI and lung NET, and advanced, progressive pNET, with the triple antitumor effect of AFINITOR.

GI, gastrointestinal; MOA, mechanism of action; mTOR, mammalian target of rapamycin; NET, neuroendocrine tumor(s); pNET; pancreatic neuroendocrine tumor(s).
