| Questions and Answers (Q&A) | Back Directory | [Description]
Irbinitinib is also known as ARRY-380 or Tucatinib. 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.

TukysaTM
| [Side effects]
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.

Store at -20°C | [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. |
