Brief Summary

Nearly half of the world's nasopharyngeal cancer occurs in China, among which the highest incidence in Guangdong and Guangxi, so the nickname "Guangdong tumor". Due to the hidden position of the nasopharynx, 70% to 80% of patients are found in the middle and late stages. Immunotherapy plays a significant role in nasopharyngeal carcinoma. Professor Ma Jun of Sun Yat-sen University reported a phase 3 clinical study at ASCO meeting in 2023, which compared the efficacy of Sintilimab combined with GP chemotherapy versus GP chemotherapy alone in locally advanced nasopharyngeal carcinoma, and the results showed that EFS in the immune group decreased by 41% in 3 years. The risk of local recurrence-free survival and distant metastasis was reduced by 48% and 43%, respectively. However, a subgroup analysis of the study found that low-risk patients benefited more, while N2-N3 patients benefited only HR There is 0.78, new treatment options need to be explored in clinic. Therefore, the investigators plan to initiate a prospective study to evaluate the efficacy and safety of Sintilimab Combined With Bevacizumab and TP Chemotherapy for high-risk locally advanced nasopharyngeal carcinoma.

Detailed Description

This study is a prospective, single-arm, multicenter, Phase II clinical study. This study was planned to include patients with histologically confirmed non-keratinized stage TanyN2-3M0 nasopharyngeal carcinoma (AJCC Version 8). Eligible enrolled patients will receive 3 cycles of induction therapy: sintilimab, bevacizumab, and TP regimen chemotherapy. After induction therapy, all patients received radical concurrent chemoradiotherapy and maintenance treatment with sintilimab.The primary endpoint is radiographic complete response rate after induction therapy.The secondary endpoint are two years PFS rate and safety which is the incidence and severity of AE evaluated according to the NCI CTCAE (version 5.0) classification of the severity of adverse events, and the correlation with the study drugs was analyzed.
