Tesetaxel is used in cancer treatment, particularly for solid tumors such as breast, gastric, and colorectal cancers. It belongs to the taxane class of chemotherapy agents and works by stabilizing microtubules, which disrupts cell division and leads to cancer cell death. One of its key advantages is oral bioavailability, allowing patients to take it in pill form rather than through intravenous infusion. This improves convenience and enables longer or more flexible dosing schedules. Tesetaxel has shown activity in tumors that are resistant to other taxanes, making it a potential option for patients who have limited responses to standard therapies. It is being studied in clinical trials both as a single agent and in combination with other anticancer drugs to enhance efficacy.
