What is TRUSELTIQ?
TRUSELTIQ is a prescription medicine used to treat adults with bile duct cancer (cholangiocarcinoma) that has spread or cannot be removed by surgery, who have already received a previous treatment, and whose tumor has a certain type of abnormal “FGFR2” gene. Your healthcare provider will test your cancer for certain FGFR2 gene abnormalities and make sure that TRUSELTIQ is right for you.
TRUSELTIQ is approved based on tumor response and duration of response. Data are not yet available to show if TRUSELTIQ improves symptoms or survival.
