This is a randomized, open, multicenter phase II/III trial to compare the efficacy and safety of QL1706 and carrilizumab combined with gemcitabine and cisplatin in first-line treatment of recurrent or metastatic nasopharyngeal carcinoma. The study is divided into two parts.~The first part is a phase II, single-arm study with an introductory safety phase, which is planned to enroll 30 subjects with nasopharyngeal carcinoma treated with first-line QL1706 in combination with gemcitabine and cisplatin. The primary objective of the first part is to evaluate the safety and tolerability of QL1706 combined with gemcitabine and cisplatin in the first-line treatment of patients with recurrent or metastatic nasopharyngeal carcinoma.~The second part is a phase III randomized, controlled study. The study plans to enroll 430 subjects, who will be randomized in a 1:1 ratio to a trial group of QL1706 in combination with gemcitabine and cisplatin and a control group of carrilizumab in combination with gemcitabine and cisplatin. The primary objective of the second part was to compare the effectiveness of QL1706 with that of carrilizumab combined with gemcitabine and cisplatin, respectively, in the first-line treatment of recurrent or metastatic nasopharyngeal carcinoma.
