GNT Induction Treatment in Locally Advanced NPC

Summary

The goal of this clinical trial is to compare overall response rate between gemcitabine, nimotuzumab and toripalimab as induction treatment and gemcitabine combined with cisplatine in paitents with locally advanced nasopharyngeal carcinoma. It aims to answer whether gemcitabine, nimotuzumab and toripalimab as induction treatment show non-inferiority compared to GP induction chemotherapy. Participants will be randomly divided into two induction treatment groups.
