Uses for fam-trastuzumab deruxtecan-nxki
Fam-trastuzumab deruxtecan-nxki injection is used to treat HER2-positive metastatic (cancer that has spread to other parts of the body) breast cancer or whose cancer cannot be removed with surgery in patients who have previously received an anti-HER2 breast cancer treatment for metastatic disease or have breast cancer that has come back during or within 6 months of completing treatment for early-stage breast cancer.
Fam-trastuzumab deruxtecan-nxki injection is also used to treat HER-2 positive metastatic (cancer that has spread to other parts of the body) or locally advanced (cancer that has spread to areas near the stomach) stomach cancer called gastric or gastroesophageal junction (GEJ) adenocarcinoma in patients who have previously received trastuzumab-based regimen.
HER2 protein is produced by some tumors. Fam-trastuzumab deruxtecan-nxki interferes with the growth of this protein which also prevents tumor growth. The tumor cells will then be destroyed by the body.
Fam-trastuzumab deruxtecan-nxki is to be given only by or under the immediate supervision of your doctor.
