Locally Advanced Nasopharyngeal Carcinoma

This phase III trial aims to evaluate the efficacy and safety of induction chemotherapy combined with serplulimab (induction/maintenance therapy) with omission of concurrent chemotherapy in patients with locally advanced nasopharyngeal carcinoma (LA-NPC).

This is a multicenter, open-label, randomized phase II clinical trial designed to evaluate the optimal timing of toripalimab administration during neoadjuvant chemotherapy in patients with locoregionally advanced nasopharyngeal carcinoma. Participants will receive gemcitabine and cisplatin (GP) chemotherapy combined with toripalimab administered on different days (Day 1, Day 5, or Day 9) to compare treatment responses. The neoadjuvant phase includes 3 cycles of 21 days each, followed by concurrent chemoradiotherapy. The estimated enrollment period is from March 2026 to March 2028.

This is a prospective, open-label, multicenter, single-arm clinical study. A total of 30 patients with locally advanced nasopharyngeal carcinoma who have not received prior systemic treatment are planned to be enrolled at three centers. After enrollment, the patients will receive induction therapy with Iparomlimab/Tuvorlimab(QL-1706) in combination with a modified TPF regimen, followed by concurrent chemoradiotherapy with cisplatin according to the standards of clinical practice.

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.

The purpose of this study was to investigate the role of immunonutrion compared with standard nutrition in reducing oral mucositis in patients with locally advanced nasopharyngeal carcinoma.

The goal of this clinical trial is to learn if the regimen of gemcitabine, cisplatin combined with nimotuzumab and sintilimab works to treat locally advanced nasopharyngeal carcinoma before chemoradiotherapy. It will also learn about the safety of the regimen. The main questions it aims to answer are: * Does the regimen increase the number of participants who has a significant tumor shrinkage? * What medical problems do participants have when taking the regimen? Researchers will evaluate the safety and efficacy of the regimen. Participants will: * Take the regimen every 21 days, for twice. * Visit the clinic weekly for drug administration, checkups and tests. * Keep a diary of their symptoms.

This trial is a multi-center phase III clinical trial. The purpose of this trial is to explore whether 2 cycles induction chemotherapy combined with concurrent chemoradiotherapy is not inferior to 3 cycles induction chemotherapy combined with concurrent chemoradiotherapy in patients with locally advanced nasopharyngeal carcinoma.

Patients diagnosed with locally advanced nasopharyngeal carcinoma will be recruited in this study. All the patients will get 3 cycles of GP+ Envafolimab for the induction chemotherapy. After that, the patients will receive concurrent chemoradiotherapy. Radiotherapy will be given by IMRT, under the dose of GTVnx 68-70Gy/30-33f, 5d/w,6-7w, during which, every patient would receive 2 cycles of DDP+Envafolimab as concurrent chemotherapy. Then patients would receive Envafolimab every 3 weeks for maintenance treatment for a year, until disease progression or intolerance of treatment. . We aim to evaluate the three years progression free survival of these patients by the combination of Envafolimab with curative chemoradiotherapy.

This trial is a multi-center phase III clinical trial. The purpose of this trial is to explore whether concurrent chemoradiotherapy is not inferior to induction chemotherapy combined with concurrent chemoradiotherapy in patients with locally advanced nasopharyngeal carcinoma.
