Nab-TPC Versus GP Chemotherapy Combined With Camrelizumab in the Treatment of Recurrent/Metastatic Nasopharyngeal Carcinoma: Randomized Controlled, Multi Center, Phase III Clinical Study

The therapeutic effect of patients with metastatic nasopharyngeal carcinoma has been further improved. Numerous previous studies have shown that anti-PD-1 immune checkpoint inhibitors (ICIs) have strong activity in treated metastatic nasopharyngeal carcinoma patients, with an objective response rate (ORR) of 20-34%. In addition, immunotherapy has also achieved good results in the first-line treatment of recurrent/metastatic nasopharyngeal carcinoma. In 2021, the clinical results of a study on the treatment of recurrent/metastatic nasopharyngeal carcinoma with pembrolizumab were published. The median PFS of the pembrolizumab combined with chemotherapy group was 9.7 months, significantly prolonging PFS, with an HR value of 0.54, and reducing the risk of disease progression by 46%. Based on this, the 2022 CSCO guidelines will use pembrolizumab combined with GP chemotherapy as a new first-line treatment for metastatic nasopharyngeal carcinoma.We conducted a study comparing the efficacy of GP regimen and nab TPC regimen, and found that nab TPC regimen significantly improved the survival of patients with metastatic nasopharyngeal carcinoma compared to GP regimen, and the nab TPC regimen group had milder grade 3-4 toxic side effects.This study aims to design a prospective phase III clinical trial on the safety and efficacy of GP combined with Carilizumab compared to nab TPC regimen combined with Carilizumab chemotherapy for recurrent and metastatic nasopharyngeal carcinoma
