Press Release

TAGRISSO® (osimertinib) Significantly Improves Progression-Free Survival in the Phase III FLAURA Trial for Lung Cancer

AstraZeneca
Posted on: 27 Jul 17

AstraZeneca today 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 once-daily tablets are approved 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 tyrosine kinase inhibitor (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.

TAGRISSO ® (osimertinib) Important Safety Information

  • There are no contraindications for TAGRISSO
  • Interstitial Lung Disease (ILD)/Pneumonitis occurred in 3.5% and was fatal in 0.6% of 833 TAGRISSO-treated patients. Withhold TAGRISSO and promptly investigate for ILD in patients who present with worsening of respiratory symptoms indicative of ILD (eg, dyspnea, cough, and fever). Permanently discontinue TAGRISSO if ILD is confirmed
  • Heart rate-corrected QT (QTc) interval prolongation occurred in TAGRISSO-treated patients. Of the 833 TAGRISSO-treated patients, 0.7% of patients were found to have a QTc > 500 msec, and 2.9% of patients had an increase from baseline QTc > 60 msec. No QTc-related arrhythmias were reported. Conduct periodic monitoring with ECGs and electrolytes in patients with congenital long QTc syndrome, congestive heart failure, electrolyte abnormalities, or those who are taking medications known to prolong the QTc interval. Permanently discontinue TAGRISSO in patients who develop QTc interval prolongation with signs/symptoms of life-threatening arrhythmia
  • Cardiomyopathy occurred in 1.9% and was fatal in 0.1% of 833 TAGRISSO-treated patients. Left Ventricular Ejection Fraction (LVEF) decline ≥ 10% and a drop to < 50% occurred in 4% of 655 TAGRISSO-treated patients. Conduct cardiac monitoring, including an assessment of LVEF at baseline and during treatment in patients with cardiac risk factors. Assess LVEF in patients who develop relevant cardiac signs or symptoms during treatment. For symptomatic congestive heart failure or persistent, asymptomatic LV dysfunction that does not resolve within 4 weeks, permanently discontinue TAGRISSO
  • Keratitis was reported in 0.7% of 833 TAGRISSO-treated patients in clinical trials. Promptly refer patients with signs and symptoms suggestive of keratitis (such as eye inflammation, lacrimation, light sensitivity, blurred vision, eye pain, and/or red eye) to an ophthalmologist
  • Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during TAGRISSO treatment and for 6 weeks after the final dose. Advise males with female partners of reproductive potential to use effective contraception for 4 months after the final dose
  • The most common adverse reactions (≥20%) in patients treated with TAGRISSO were diarrhea (41%), rash (34%), dry skin (23%), nail toxicity (22%), and fatigue (22%)

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 secondary 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 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 epidermal growth factor receptor (EGFR) T790M mutation-positive advanced non-small cell lung cancer (NSCLC). 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 first-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 TAGRISSO® (osimertinib) 80mg once-daily treatment versus 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 (NSCLC). The trial was a double-blinded, randomized study, with 556 patients across 30 countries.

The primary endpoint of the trial was progression-free survival (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).
