The Generic and Brand Name Distinction
Drugs typically have both a brand name and a generic name. The brand name, like Tukysa, is given by the manufacturer for marketing, while the generic name, tucatinib, refers to the active chemical ingredient. Understanding this difference is important for patients and healthcare providers to ensure correct identification of the drug in medical records, prescriptions, and communication, helping to avoid confusion with other medications.
Other Known Identifiers
During its development, tucatinib was also known by the code names ONT-380 and ARRY-380 before receiving FDA approval and the brand name Tukysa. These identifiers are primarily relevant to its clinical trial history but highlight the importance of recognizing the generic name, tucatinib.
How Tucatinib Works: A Kinase Inhibitor
Tucatinib (Tukysa) is a targeted therapy classified as a kinase inhibitor that specifically targets the human epidermal growth factor receptor 2 (HER2). It works by inhibiting the phosphorylation of HER2 inside cancer cells, blocking the signaling pathways that promote growth and division, particularly in HER2-positive cancers where this protein is overexpressed. Tucatinib complements other HER2 therapies that may act on the outside of the cell, providing a comprehensive approach to blocking HER2-driven cancer growth.
