AstraZeneca announced the submission of a supplemental new drug application (sNDA) to Japan’s Pharmaceuticals and Medical Devices Agency for the use of Tagrisso (osimertinib), a third-generation, irreversible epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) with clinical activity against central nervous system (CNS) metastases, for the 1st-line treatment of patients with inoperable or recurrent EGFR mutation-positive (EGFRm) non-small cell lung cancer (NSCLC).
The Japan sNDA is based on data from the Phase III FLAURA trial, in which Tagrisso significantly improved progression-free survival (PFS) compared to current 1st-line EGFR-TKIs, erlotinib or gefitinib, in previously-untreated patients with locally-advanced or metastatic EGFRm NSCLC.
