Brief summary: This study is to investigate the efficacy and safety of the induction chemotherapy + concurrent chemoradiotherapy（CCRT）combined with toripalimab and endostar treatment, in comparison with the induction chemotherapy + concurrent chemoradiotherapy（CCRT）, in treating locally advanced high-risk nasopharyngeal carcinoma

Detailed description: GP-induced chemotherapy combined with concurrent chemoradiotherapy is the standard treatment for the locally advanced nasopharyngeal carcinoma recommended by the guidelines. However, the prognosis for T4 and/or N3 nasopharyngeal carcinoma is still poor, with the 3-year PFS of about 70%. Therefore, it is of great importance to improve the prognosis of patients with locally advanced high-risk nasopharyngeal carcinoma. Immunotherapy has been an emerging treatment method for tumors in recent years. Compared with the chemotherapy, immunotherapy has less adverse reactions, and the effects could last longer, significantly improving the prognosis and patients' quality of life. Endostar, as a VEGFR inhibitor, has good safety in treating nasopharyngeal carcinoma. Related data have shown that PD-1 and Endostar exert synergistic antitumor effects in a mouse model of lung cancer. A Phase II multi-center clinical study from our center has shown that, for patients with locally advanced low-risk nasopharyngeal carcinoma, all the 3-year OS, PFS, and DMFS for the radiotherapy combined with Endostar group were superior to the concurrent chemoradiotherapy group, and the combination of radiotherapy and Endostar lead to significantly reduced adverse effects. In clinical studies concerning other solid tumors, it has also been observed that the PD-1 inhibitors combined with VEGFR inhibitors could significantly improve the efficacy, and achieve synergistic effects. Therefore, A Phase II，randomized, prospective, multicentric clinical trail was conducted to compare the efficacy and safety of induction chemotherapy and the concurrent chemoradiotherapy plus Endostar and PD-1, followed by PD-1 treatment for half a year compared with the induction chemotherapy and the concurrent chemoradiotherapy for the T4 and/or N3 nasopharyngeal carcinoma.
