What is Zegfrovy?

Zegfrovy is used to treat non-small cell lung cancer (NSCLC) that is locally advanced or has metastasized and with an abnormal epidermal growth factor receptor (EGFR) gene, in adults whose disease has worsened while on or after chemotherapy that contains platinum. It is an oral tablet taken 1 time a day.

Zegfrovy is a targeted drug that works by blocking EGFR, a protein that promotes cancer growth. It specifically targets EGFR exon 20 insertion mutations found in some lung cancers. In laboratory clinical trials, it effectively stopped cancer cell growth and shrank tumors in animal models with these specific mutations. Zegfrovy belongs to the drug class called kinase inhibitors.

Zegfrovy (sunvozertinib) gained FDA approval on July 2, 2025. There is no generic.
