EC approves AstraZeneca’s Tagrisso to treat mutation-positive NSCLC

PBR Staff Writer Published 26 April 2017

AstraZeneca has secured full marketing authorization from the European Commission (EC) for its Tagrisso (osimertinib) 40mg and 80mg once-daily tablets to treat adult patients with locally-advanced or metastatic epidermal growth factor receptor (EGFR) T790M mutation-positive non-small cell lung cancer (NSCLC).

Tagrisso 40mg and 80mg once-daily oral tablet were approved in around 45 countries, including the US, EU, Japan and China, to treat patients with EGFR T790M mutation-positive advanced NSCLC.

Tagrisso is a third generation and irreversible EGFR-TKI, which can inhibit both EGFR sensitising and EGFR T790M resistance mutations. It is also said to have activity in the CNS.

The approval was based on results of the Phase III AURA3 trial, which showed statistically-significant improvements in progression-free survival (PFS) against standard platinum-based doublet chemotherapy in 419 patients with EGFR T790M-positive advanced NSCLC whose disease had progressed on or after EGFR TKI therapy.

In March, the US Food and Drug Administration (FDA) has granted approval for Tagrisso 80mg once-daily tablets to treat patients with EGFR T790M mutation-positive NSCLC. It also secured approval in China through the priority review pathway.

Earlier, the firm secured fast track, breakthrough therapy and priority review designation for Tagrisso from the FDA.

In addition, Tagrisso is being assessed in the adjuvant and metastatic first line settings, including in patients with and without CNS metastases, leptomeningeal metastases and combination with other treatments.

AstraZeneca global medicines development executive vice president and chief medical officer Sean Bohen said: “The full approval of Tagrisso in the EU is further evidence of our exciting progress in transforming the science of cancer care to deliver life-changing medicines to people most in need.

“Having demonstrated its superiority over chemotherapy in EGFR T790M mutation-positive non-small cell lung cancer, Tagrisso has the potential to become the new standard of care for patients with this difficult-to-treat form of lung cancer.”
