GIOTRIF® (afatinib) approved by Health Canada for patients with metastatic adenocarcinoma of the lung with activating EGFR mutation
On November 6, 2013, Health Canada approved GIOTRIF® (afatinib) a targeted, oral once-daily tyrosine kinase inhibitor and the first irreversible ErbB Family Blocker approved for the treatment of EGFR mutation positive tyrosine kinase inhibitor naïve patients with metastatic adenocarcinoma of the lung with activating EGFR mutation(s) tablets.
In clinical trials, GIOTRIF® has been shown to offer patients with EGFR mutation positive NSCLC a significant delay in tumour progression,[i] coupled with improvements in their lung cancer related symptoms versus standard chemotherapy.[i]
Dr. Vera Hirsh, GIOTRIF® clinical trial investigator and medical oncologist at Royal Victoria Hospital in Montreal says, “The approval of GIOTRIF® is an exciting advancement because it works differently than other drugs in its class, by irreversibly blocking multiple EGFR pathways involved in tumour growth.”
GIOTRIF®’s unique mode of action enables it to block EGFR (ErbB1) as well as the other relevant members of the ErbB Family. The covalent and, therefore, irreversible binding of GIOTRIF® is unlike other compounds currently on the market which are reversible in that it provides a sustained, selective, and complete ErbB Family Blockade.[i],[ii]
Discovered and developed by Boehringer Ingelheim, GIOTRIF® is the first Health Canada-approved oncology product from the company.
