简要总结
The study is to evaluate the efficacy of KL-A167 combined with cisplatin and gemcitabine vs placebo combined with cisplatin and gemcitabine in the treatment of recurrent or metastatic nasopharyngeal carcinoma, as measured by progression-free survival (PFS) per the Response Evaluation Criteria in Solid Tumors RECIST Version 1.1
详细描述
This study is a randomized, double-blind, placebo-controlled and multicenter study. It is expected that patients with recurrent or metastatic nasopharyngeal carcinoma who had not received systematic anti-tumor treatment before are enrolled, and the efficacy and safety of KL-A167 injection combined with cisplatin and gemcitabine are compared with placebo combined with cisplatin and gemcitabine in the treatment of recurrent or metastatic nasopharyngeal carcinoma. Subjects who meet the enrollment requirements will be randomized to the trial group or the control group according to the ratio of 2:1. The stratification factors are: liver metastasis (with vs without) and ECOG score (0 vs 1)
