简要总结
This is an Open Label, Non-Inferiority, Multicenter, Randomized Phase 3 Trial aimed to investigate the impact of reduced-dose radiotherapy in combination with chemotherapy and immunotherapy on patients' prognosis and complication compared with conventional-dose radiotherapy in combination with chemotherapy and immunotherapy for treatment-sensitive stage III NPC patients screened out according to the treatment response.
详细描述
The goals of this clinical trial includes: ① To confirm whether LRRFS after reduced-dose radiotherapy in combination with chemotherapy and immunotherapy is non-inferior to LRRFS after conventional-dose radiotherapy in combination with chemotherapy and immunotherapy for treatment-sensitive stage III NPC patients screened out according to the treatment response; ② To explore the impact of reduced-dose radiotherapy on 3-year OS, 3-year PFS, 3-year DMFS, 3-year LRFS and 3-year RRFS for treatment-sensitive stage III NPC patients screened out according to the treatment response; ③ To explore the impact of reduced-dose radiotherapy on radiotherapy complications and quality of life; ④ To explore the interaction between different clinical factors and the impact of reduced-dose radiotherapy on the prognosis of patients; ⑤ To explore the biomarkers of sensitivity to chemotherapy and radiotherapy for patients with nasopharyngeal carcinoma and the underlying mechanism.
For these purposes, we plan to prospectively enroll stage III NPC patients from hospitals in China. The participants will receive 3 cycles of induction chemotherapy (GP regimen + Camrelizumab) followed by intensity-modulated radiation therapy. 2 cycles of concurrent chemotherapy will be administered during the radiotherapy. Patients' treatment response will be evaluated with MRI examination after 27 fractions of radiotherapy. If the treatment response after 27 fractions of radiotherapy is complete remission, the participants will be randomized into reduced-dose radiotherapy group and conventional-dose radiotherapy group. If the treatment response after 27 fractions of radiotherapy is not complete remission, the participants will be assigned to the unenrolled group. All the participants in the unenrolled group will receive conventional-dose radiotherapy. After the radiotherapy, all the participants will receive 9 cycles of Camrelizumab immunotherapy. Besides, all the participants in the unenrolled group will also receive metronomic adjuvant capecitabine chemotherapy for 1 year. The prognosis, complication, and quality of life will be compared between the reduced-dose radiotherapy group and the conventional-dose radiotherapy group.
