How Osimertinib Works

Osimertinib is a third-generation EGFR tyrosine kinase inhibitor (TKI). It specifically targets and inhibits the EGFR T790M mutation, which is a common cause of resistance to first-line EGFR inhibitors.

Key Benefits of Osimertinib

• Highly effective against EGFR-mutated NSCLC.
• Crosses the blood-brain barrier, helping to treat brain metastases.
• Fewer side effects compared to chemotherapy.
• Improves overall survival rates and delays cancer progression.

Uses of Osimertinib

Osimertinib is primarily prescribed for:

• First-line treatment of EGFR-mutated NSCLC – Effective in patients newly diagnosed with EGFR exon 19 deletions or exon 21 L858R mutations.
• Treatment of EGFR T790M-positive NSCLC – Used when cancer becomes resistant to first-line EGFR inhibitors.
• Prevention of recurrence in early-stage NSCLC – Approved as an adjuvant therapy to reduce the risk of cancer returning after surgery.
