Phase III FLAURA trial of Tagrisso meets endpoint in untreated NSCLC EGFR

AstraZeneca announced positive overall survival (OS) results from the Phase III FLAURA trial, a randomised, double-blinded, multi-centre trial of Tagrisso (osimertinib) in previously-untreated patients with locally-advanced or metastatic non-small cell lung cancer (NSCLC) whose tumours have epidermal growth factor receptor (EGFR) mutations. Tagrisso showed a statistically-significant and clinically-meaningful improvement in OS, a secondary endpoint in the FLAURA Phase III trial, compared with erlotinib or gefitinib both of which were previous standard-of-care (SoC) treatments in this setting.

The FLAURA trial met its primary endpoint in July 2017, showing a statistically-significant and clinically-meaningful improvement in progression-free survival (PFS), increasing the time patients lived without disease progression or death from any cause. The safety and tolerability of Tagrisso was consistent with its established profile. AstraZeneca plans to present the OS results from the FLAURA trial at a forthcoming medical meeting.

Comment:In the US, Tagrisso is approved for first line treatment of NSCLC with epidermal growth factor receptor (EGFR) mutations, and for the 2nd-line treatment of patients with metastatic EGFRm NSCLC, whose disease has progressed on or after a 1st-line EGFR-TKI therapy and who have developed the secondary T790M mutation, as detected by an FDA-approved test.
