Ripretinib is a powerful medication that targets specific proteins in cancer cells to stop their growth and spread. It works by blocking the activity of certain proteins called tyrosine kinases, including KIT and PDGFRα, which are known to fuel the growth of tumors. By doing this, Ripretinib helps to slow down the growth of cancer cells and may even cause them to die. Additionally, it also blocks other proteins that support tumor growth such as PDGFRβ, TIE2, VEGFR2, and BRAF. Overall, Ripretinib offers hope in the fight against cancer by targeting multiple pathways that drive the disease.
