简要总结
This is a single-arm, multicenter, prospective, open-label phase II clinical trial of multi-target radiotherapy combined with PD-1 monoclonal antibody and capecitabine maintenance therapy treating oligometastatic nasopharyngeal carcinoma, the main purpose of which is to evaluate the efficacy of multi-target radiotherapy combined with PD-1 monoclonal antibody and capecitabine maintenance therapy regimen in treating oligometastatic nasopharyngeal carcinoma.
详细描述
This is a single-arm, multicenter, prospective, open-label phase II clinical study of multi-target radiotherapy combined with PD-1 monoclonal antibody and capecitabine maintenance therapy for oligometastatic nasopharyngeal carcinoma. Its primary objective is to assess the efficacy, including progression-free survival (PFS), 2-year overall survival (Two-year OS) and progression-free survival (Two-year PFS), overall survival (OS), duration of response (DOR) and safety of multi-target radiotherapy combined with PD-1 monoclonal antibody and capecitabine maintenance therapy in treating oligometastatic nasopharyngeal carcinoma. The secondary objective is to explore the potential genetic biomarkers and clinical therapeutic efficacy evaluation and prediction model of multi-target radiotherapy combined with PD-1 monoclonal antibody and capecitabine maintenance therapy regimen in treating oligometastatic nasopharyngeal carcinoma, providing the evidence of the screening of the potential patients benefiting from the regimen of this trial.
