What is Tagrisso (osimertinib) for?
Tagrisso (osimertinib) is a kinase inhibitor indicated for the treatment of patients with a specific type of lung cancer (metastatic epidermal growth factor receptor (EGFR) T790M mutation positive non-small cell lung cancer (NSCLC))
- as first-line treatment of patients whose tumours have EGFR exon 19 deletions or exon 21 L858R mutations.
- as second line treatment of patients whose disease has progressed on or after EGFR TKI therapy.
The activity of the epidermal growth factor receptor (EGFR) normally controls growth and division of cells. In lung cancer cells, the EGFR is often overactive, causing uncontrolled division of cancer cells. By blocking the EGFR, osimertinib helps to reduce the growth and spread of the cancer. Unlike most other tyrosine kinase inhibitors, Tagrisso (osimertinib) is active against cancer cells with the T790M mutation in the EGFR gene.
