For which conditions is this drug approved? Tagrisso is a kinase inhibitor used to treat patients with metastatic epidermal growth factor receptor (EGFR) T790M mutation-positive non-small cell lung cancer (NSCLC) whose cancer has progressed on or after EGFR tyrosine kinase inhibitor therapy.

What is the mechanism of action? Some non-small cell lung cancer cells express certain EGFR mutations. Therefore, researchers have designed Tagrisso to specifically target and bind to these particular mutations. Once binding has occurred, these cancer cells are killed.

How is Tagrisso typically given (administered)? Tagrisso is taken orally once per day. It can be taken with or without food and should not be double-dosed if a dose is missed.
