What is the mechanism of action of tucatinib/tucatinib? How does it work?

Tucatinib/Tucatinib is a human epidermal growth factor receptor -2 (HER2) inhibitor that helps patients with advanced breast cancer or colorectal cancer slow down or stop the growth of cancer cells by blocking the her 2 protein. Some cancers overexpress the HER2 protein, causing cancer cells to grow and spread. Tucatinib is an oral targeted drug therapy that is highly selective for the HER2 protein and acts intracellularly. Tucatinib binds to HER2's tyrosine kinase (an enzyme) and reduces PI3 PI3 kinase and MAP kinase signaling. The weakened signal helps prevent cell growth and leads to cell death. Tucatinib is classified as a HER2 tyrosine kinase inhibitor.

Tucatinibis used with the drugs trastuzumab (Herceptin) and capecitabine (Xeloda) in adults with HER2positive breast cancer, including cancer that has spread to the brain. It is used in patients who have received one or more anti-HER2 breast cancer treatments that no longer respond. It is also indicated in combination with trastuzumab for the treatment of RAS wild-type HER2-positive unresectable or metastatic colorectal cancer in adult patients who have progressed following fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy. This method is used when the cancer has spread within the body (metastatic) or cannot be removed with surgery (unresectable). There is a generic version of this drug in Bangladesh.
