Beschreibung
Tucatinib is also known as ARRY-380 or Irbinitinib. ARRY-380 is an orally inhibitor of human epidermal growth factor receptor tyrosine kinase ErbB-2 (also called HER2) with potential antineoplastic activity. It selectively binds to and inhibits the phosphorylation of ErbB-2, which may prevent the activation of ErbB-2 signal transduction pathways, resulting in growth inhibition and death of ErbB-2-expressing tumor cells. ErbB-2 is overexpressed in a variety of cancers and plays an important role in cellular proliferation and differentiation. Therefore, ARRY-380 may be an alternative treatmentmethod for the treatment of HER2+ cancers.

Verwenden
Tucatinib, a highly selective HER2 inhibitor, was approved in 2020 as a combination therapy with trastuzumab and capecitabine for the treatment of patients with advanced unresectable or metastatic HER2-positive breast cancer, including patients with brain metastases, who have received one or more prior anti-HER2-based regimens in the metastatic setting.

Nebenwirkungen
Tukysa (tucatinib) is a brand-name prescription medication. The Active ingredient is tucatinib. Serious side effects can include diarrhoea, liver damage, and allergic reactions. Mild side effects can occur with Tukysa use. This list doesn’t include all possible mild side effects of the drug. Mild side effects that have been reported with Tukysa include nausea and vomiting, fatigue, reduced appetite, weight loss, joint pain; peripheral neuropathy (nerve damage that causes tingling, numbness, or weakness in your arms, hands, legs, or feet); abdominal pain; headache; skin rash; nosebleeds; anemia (low level of red blood cells); stomatitis; hand-foot syndrome.

Mode of action
Tucatinib binds to tyrosine kinase (an enzyme) of HER2, reducing PI3-kinase and MAP-kinase signaling. In vitro, tucatinib inhibits phosphorylation of HER2 and HER3, resulting in inhibition of downstream MAPK and AKT signaling and cell proliferation, and showed anti-tumor activity in HER2 expressing tumor cells. In vivo, tucatinib inhibited the growth of HER2 expressing tumors. The combination of tucatinib and trastuzumab showed increased anti-tumor activity in vitro and in vivo compared to either drug alone.
