AstraZeneca: Tagrisso could replace chemo for some
There is a potential to become the new standard of care for 2nd-line treatment of patients with epidermal growth factor receptor (EGFR) T790M mutation-positive locally-advanced or metastatic non-small cell lung cancer (NSCLC).
The first randomised Phase III data showed that Tagrisso 2nd-line therapy improved progression-free survival (PFS) by 5.7 months compared with standard platinum-based doublet chemotherapy.
The results were presented at the 17th World Conference on Lung Cancer (WCLC) in Vienna, Austria, hosted by the International Association for the Study of Lung Cancer, and published simultaneously online in The New England Journal of Medicine.
AURA3 data showed Tagrisso offered a statistically-significant improvement in PFS versus standard platinum-based doublet chemotherapy (10.1 months vs 4.4 months).
In the 34% of patients with central nervous system (CNS) metastases at baseline, PFS was also significantly greater with Tagrisso than with platinum-based doublet chemotherapy (8.5 months vs 4.2 months).
Professor Tony Mok, from the Chinese University of Hong Kong, Hong Kong said: “The superiority of Tagrisso in progression free survival and response rate over platinum-pemetrexed chemotherapy suggests we may be moving towards a new standard of care for patients with resistance to EGFR TKI.
"With the publication of the AURA3 data, clinicians should perform T790M mutation testing to ensure Tagrisso be given to patients who are most likely to benefit.”
Tagrisso was granted accelerated approval by the US Food and Drug Administration (FDA) in November 2015 for the treatment of patients with metastatic EGFR T790M mutation-positive NSCLC, as detected by an FDA-approved test, who have progressed on or after EGFR TKI therapy.
In the EU, Tagrisso was granted conditional marketing authorisation for adult patients with locally advanced or metastatic EGFR T790M NSCLC, irrespective of previous EGFR-TKI treatment by the European Medicines Agency (EMA) in February 2016.
In addition, Tagrisso received approval in Japan in March 2016 for the treatment of patients with EGFR T790M mutation-positive inoperable or recurrent NSCLC that is resistant to EGFR TKI therapy, and it is currently under fast track review in China, where nearly half of lung cancer patients are thought to have the EGFR mutation. ■
