AstraZeneca announced that the phase III FLAURA trial showed a statistically-significant and clinically-meaningful progression-free survival (PFS) benefit with Tagrisso (osimertinib) compared to current 1st-line standard-of-care treatment (erlotinib or gefitinib) in previously-untreated patients with locally-advanced or metastatic epidermal growth factor receptor mutation-positive (EGFRm) non-small cell lung cancer (NSCLC).

Sean Bohen, executive vice president, global medicines development and chief medical officer at AstraZeneca, said: “The strong results from the FLAURA trial are very exciting news for patients with EGFR mutation-positive non-small cell lung cancer, providing physicians with a potential new first-line treatment option to improve outcomes in this disease. We will now initiate discussions with global health authorities on the data and regulatory submissions.”

The efficacy, safety and tolerability profiles for Tagrisso, erlotinib and gefitinib were consistent with current knowledge. A full evaluation of the FLAURA data is ongoing. Further results will be presented at a forthcoming medical meeting.

Tagrisso is a third generation, irreversible EGFR tyrosine kinase inhibitor (TKI) designed to inhibit both EGFR sensitising and EGFR T790M resistance mutations, with clinical activity against central nervous system (CNS) metastases. Tagrisso (osimertinib) 40mg and 80mg once-daily oral tablets have been approved in more than 50 countries, including the US, EU, Japan and China, for patients with EGFR T790M mutation-positive advanced NSCLC. Tagrisso is also being investigated in the adjuvant and metastatic first-line settings, including in patients with and without CNS metastases, in leptomeningeal metastases, and in combination with other treatments.

FLAURA assessed the efficacy and safety of Tagrisso 80mg once-daily treatment versus standard-of-care EGFR-TKIs (either erlotinib [150mg orally, once daily] or gefitinib [250mg orally, once daily]) in previously untreated patients with locally advanced or metastatic EGFR mutation-positive NSCLC. The trial was a double-blinded, randomised study, with 556 patients across 30 countries.

The primary endpoint of the trial was PFS, and secondary endpoints included overall survival, objective response rate, duration of response, disease control rate, safety and measures of health-related quality of life (HRQoL).

AstraZeneca is a global, science-led biopharmaceutical company that focuses on the discovery, development and commercialisation of prescription medicines, primarily for the treatment of diseases in three main therapy areas - oncology, cardiovascular & metabolic diseases and respiratory.
