The US Food and Drug Administration has granted full approval for Tagrisso (osimertinib) 80mg once-daily tablets, for the treatment of patients with metastatic epidermal growth factor receptor (EGFR) T790M mutation-positive non-small cell lung cancer (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, and efficacy data suggest it may be a new standard of care for these patients.
“By following the science, we aim to turn lung cancer into a chronic, manageable disease for patients and this milestone brings us one step closer to that ambition. The FDA’s full approval reinforces the potential of Tagrisso to become the standard of care for patients with metastatic EGFR T790M mutation-positive non-small cell lung cancer whose disease has progressed on or after first-generation EGFR-TKI therapy,” said Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer at AstraZeneca.
The full approval in the US is based on data from the randomised, Phase III AURA3 trial, in which Tagrisso significantly improved progression-free survival (PFS) versus platinum-based doublet chemotherapy, providing 10.1 months of median PFS compared to 4.4 months from chemotherapy (hazard ratio 0.30; 70% risk reduction; 95% Confidence Interval [CI]: 0.23; 0.41; P<0.001). The results of this trial were recently presented at the 17th World Conference on Lung Cancer (WCLC) in Vienna, Austria, and published in The New England Journal of Medicine.
