The generic name of Tuoyi drug is Trepolizumab Injection. It is a therapeutic method to control and eliminate tumors by restarting and maintaining the tumor-immunity cycle and restoring the normal anti-tumor immune response of the body, and is clinically used for the treatment of advanced melanoma, uroepithelial carcinoma and nasopharyngeal carcinoma. Triptolizumab achieves the effect of cancer treatment by binding with the receptors on the surface of T cells, which are immune cells in cancer patients, thus activating the T cells to play the effect of killing cancer cells. Currently, studies have confirmed the effectiveness of Trepilizumab in treating advanced melanoma, metastatic uroepithelial carcinoma and advanced nasopharyngeal carcinoma, which have failed systemic therapy. Since the use of Trepilizumab may cause a variety of side effects, it should be used only under the guidance of a professional doctor.
