Tagrisso
Tagrisso (osimertinib) is a targeted therapy used to treat non-small cell lung cancer (NSCLC). It works by blocking the activity of a specific protein called EGFR, which is often mutated in NSCLC cells. By inhibiting EGFR, Tagrisso prevents the cancer cells from growing and spreading.
Mechanism of Action, Tagrisso
Tagrisso is a tyrosine kinase inhibitor (TKI) that specifically targets the epidermal growth factor receptor (EGFR). EGFR is a protein found on the surface of cells that plays a role in cell growth and division. When EGFR is mutated, it can become overactive and lead to uncontrolled cell growth, which is a hallmark of cancer.
Tagrisso works by binding to the mutated EGFR protein and blocking its activity. This prevents the EGFR protein from sending signals that tell the cancer cells to grow and divide. As a result, Tagrisso can slow or stop the growth of NSCLC tumors.
Targeted Genetic Mutations
Tagrisso is specifically designed to target NSCLC cells that have certain mutations in the EGFR gene. The most common EGFR mutations targeted by Tagrisso include:
