Tucatinib is a kinase inhibitor used to treat certain types of unresectable/metastatic HER-2 positive breast cancer.
Mutations in the HER-2 gene are observed in some types of breast carcinoma. Tucatinib inhibits the tyrosine kinase enzyme of the HER-2 gene. Mutations of tyrosine kinase in the HER-2 gene lead to cascade effects of increased cell signaling and proliferation, resulting in malignancy. Results of in vitro studies show that tucatinib inhibits the phosphorylation of both HER-2 and HER-3, leading to downstream changes in MAPK and AKT signaling and cell proliferation. Anti-tumor activity occured in the cells that expressed HER-2. In vivo, tucatinib has been shown to inhibit HER-2 expressing tumors, likely by the same mechanism.
