TAGRISSO (osimertinib mesylate)

Kinase Inhibitors Genetically Validated
Oncology Approved 2015-11-13

TAGRISSO is indicated for the treatment of Adjuvant therapy after tumor resection in adult patients with EGFR exon 19 deletions or exon 21 L858R mutation-positive non-small cell lung cancer (NSCLC); Locally advanced, unresectable (stage III) EGFR exon 19 deletions or exon 21 L858R mutation-positive NSCLC that has not progressed during or following platinum-based chemoradiation therapy; First-line treatment of adult patients with metastatic EGFR exon 19 deletions or exon 21 L858R mutation-positive NSCLC; First-line treatment of adult patients with locally advanced or metastatic EGFR exon 19 deletions or exon 21 L858R mutation-positive NSCLC, in combination with pemetrexed and platinum-based chemotherapy; Metastatic EGFR T790M mutation-positive NSCLC in patients whose disease has progressed on or after EGFR tyrosine kinase inhibitor therapy.

How TAGRISSO Works

Osimertinib is a kinase inhibitor that binds irreversibly to mutant forms of the epidermal growth factor receptor (EGFR), such as exon 19 deletions and L858R mutations. By targeting these mutations at lower concentrations than wild-type EGFR, the drug inhibits the signaling pathways that drive tumor growth. The medication and its active metabolites also inhibit other kinases, including HER2 and HER4, and have demonstrated the ability to distribute to the brain in animal models.

What TAGRISSO Treats

5 indications

TAGRISSO is approved for 5 conditions since its original approval in 2015. These indications span multiple therapeutic areas including oncology, immunology, and more.

  • Adjuvant therapy after tumor resection in adult patients with EGFR exon 19 deletions or exon 21 L858R mutation-positive non-small cell lung cancer (NSCLC)
  • Locally advanced, unresectable (stage III) EGFR exon 19 deletions or exon 21 L858R mutation-positive NSCLC that has not progressed during or following platinum-based chemoradiation therapy
  • First-line treatment of adult patients with metastatic EGFR exon 19 deletions or exon 21 L858R mutation-positive NSCLC
  • First-line treatment of adult patients with locally advanced or metastatic EGFR exon 19 deletions or exon 21 L858R mutation-positive NSCLC, in combination with pemetrexed and platinum-based chemotherapy
  • Metastatic EGFR T790M mutation-positive NSCLC in patients whose disease has progressed on or after EGFR tyrosine kinase inhibitor therapy

TAGRISSO Target & Pathway

Pro

Target

HER2 (Human Epidermal Growth Factor Receptor 2) Growth Factor Receptor

A receptor tyrosine kinase that promotes cell growth and division. Approximately 20% of breast cancers overexpress HER2, leading to aggressive tumor growth. Targeting HER2 blocks these growth signals and can trigger immune-mediated destruction of cancer cells.

Pathway Context

HER2 forms dimers with other HER family members to activate growth signaling

HER3 (Human Epidermal Growth Factor Receptor 3)
EGFR (Epidermal Growth Factor Receptor) receptor

A receptor that triggers cell growth, proliferation, and survival when activated. Mutations or overexpression of EGFR drive many cancers, particularly lung cancer. Blocking EGFR stops the growth signals that fuel tumor progression.
