In Brief: A New Non-Small Cell Lung Cancer Indication for Osimertinib (Tagrisso)

The oral kinase inhibitor osimertinib (Tagrisso – AstraZeneca), which has been available for years for treatment of non-small cell lung cancer (NSCLC) in adults with epidermal growth factor receptor (EGFR) exon 19 deletions or exon 21 L858R mutations, has now been approved for treatment of unresectable stage III EGFR-mutated NSCLC.1 About 20-30% of patients with NSCLC have locally advanced stage III NSCLC, and 60-90% of these patients have unresectable disease. Osimertinib is the first targeted therapy to be approved for the new indication.
