Tesetaxel is an orally administered taxane being investigated as a chemotherapy agent for various types of cancer, including breast cancer,[1] gastric cancer,[2] colorectal cancer,[3] and other solid tumors.[4] It differs from other members of the taxane class (e.g. paclitaxel or docetaxel) in that it is administered orally, not intravenously.[5]
