Phase III FLAURA trial results show TAGRISSO reduced the risk of progression or death by more than half, with consistent results across all subgroups, including those with and without brain metastases
Superior median progression-free survival (PFS) of 18.9 months compared with 10.2 months for the current standard of care
Clinically meaningful trend in overall survival benefit
AstraZeneca today announced the full results of the Phase III FLAURA trial, which support TAGRISSO®’s (osimertinib) clear potential as a new standard of care (SoC) in the 1st-line treatment of adult patients with locally-advanced or metastatic epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC).
Results of the Phase III FLAURA trial were included at the Presidential Symposium I of the European Society of Medical Oncology (ESMO) 2017 Congress in Madrid, Spain, and demonstrate a superior, clinically-meaningful progression-free survival (PFS) with osimertinib compared to current SoC EGFR tyrosine kinase inhibitors (TKIs) (erlotinib or gefitinib).
Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer at AstraZeneca, said: “The FLAURA data are truly exciting. Until now, even with the therapeutic advances offered by the first- and second-generation EGFR inhibitors, less than 20% of EGFR mutation-positive NSCLC patients survive for five years. The FLAURA data suggest early and sustained benefit with TAGRISSO that has the potential to significantly impact long-term patient outcomes and help address the considerable unmet need that remains.”
Dr. Suresh S. Ramalingam, Principal Investigator of the FLAURA study, from the Winship Cancer Institute of Emory University, Atlanta, GA, said: “The FLAURA data are likely to result in a major paradigm shift in the treatment of patients with EGFR mutation-positive advanced lung cancer. Not only did the trial demonstrate a robust improvement in efficacy with osimertinib when compared to other commonly-used EGFR inhibitors, the side effects profile was also more favorable with osimertinib.”

Highlights from the FLAURA data presented include:
The FLAURA safety data for osimertinib was in line with that observed in prior clinical trials, with a low rate of Grade ≥3 adverse events (AEs). In patients treated with osimertinib, the most common AEs were diarrhea (58%, any grade [2% Grade ≥3]) and dry skin (32%, any grade [<1% Grade ≥3]), and in the comparator arm group the most common AEs were diarrhea (57%, any grade [2% Grade ≥3]) and dermatitis acneiform (48%, any grade [5% Grade ≥3]). Of the patients on osimertinib, 33.7% had a Grade ≥3 AE, compared to 44.8% in the comparator arm, and 13.3% of patients on osimertinib had an AE leading to treatment discontinuation compared to 18.1% in the comparator arm.
This indication is not yet FDA approved. AstraZeneca is in discussions with global health authorities regarding regulatory submissions for osimertinib based on the FLAURA data. A status of regulatory submissions is usually provided with the Company’s quarterly results announcement.
TAGRISSO once-daily tablets are approved by the US Food and Drug Administration (FDA) for the treatment of patients with metastatic EGFR T790M mutation-positive NSCLC, as detected by an FDA-approved test, whose disease has progressed on or after an EGFR TKI therapy. TAGRISSO is the first and only approved medicine in the US indicated for NSCLC patients who have tested positive for the EGFR T790M mutation.

NOTES TO EDITORS
About Non-Small Cell Lung Cancer (NSCLC)
Lung cancer is the leading cause of cancer death among both men and women, accounting for about one-quarter of all cancer deaths, more than breast, prostate and colorectal cancers combined. Approximately 10% to 15% of patients in the US and Europe, and 30% to 40% of patients in Asia have epidermal growth factor receptor mutation-positive (EGFRm) NSCLC. These patients are particularly sensitive to treatment with currently-available EGFR tyrosine kinase inhibitors (TKIs), which block the cell signaling pathways that drive the growth of tumor cells. However, tumors almost always develop resistance to EGFR-TKI treatment, leading to disease progression. Approximately half of patients develop resistance to approved EGFR-TKIs, such as gefitinib and erlotinib, due to the resistance mutation, EGFR T790M. TAGRISSO targets this secondary mutation that leads to disease progression. There is also a need for agents with improved central nervous system efficacy since approximately 25% of patients with EGFRm NSCLC have brain metastases at first diagnosis, increasing to approximately 40% within two years of diagnosis.
About TAGRISSO® (osimertinib)
TAGRISSO® (osimertinib) is a third-generation, irreversible epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) designed to inhibit both EGFR sensitizing and EGFR T790M resistance mutations, with clinical activity against central nervous system (CNS) metastases. TAGRISSO 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 non-small cell lung cancer. Eligibility for treatment with TAGRISSO is dependent on confirmation that the EGFR T790M mutation is present in the tumor.
TAGRISSO is also being investigated in the adjuvant and metastatic 1st-line settings, including in patients with and without CNS metastases, in leptomeningeal metastases and in combination with other treatments.
About FLAURA
FLAURA assessed the efficacy and safety of osimertinib 80mg orally once daily vs. standard-of-care epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (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 non-small cell lung cancer. The trial was a double-blinded, randomized study, with 556 patients across 30 countries.
The primary endpoint of the trial was progression-free survival, and secondary endpoints included overall survival, objective response rate, duration of response, disease control rate, safety and measures of health-related quality of life.
