Clinical Trial Summary

This study aims to investigate the efficacy and safety of neoadjuvant Toripalimab combined with Nimotuzumab in primary limited stage oral squamous cell carcinoma prior to radical therapy.

Description:

The purpose of this study is to investigate the efficacy and safety of neoadjuvant PD-1 inhibitor toripalimab plus nimotuzumab in subjects with primary limited stage, oral squamous cell carcinoma prior to radical therapy. Patients would be treated with neoadjuvant toripalimab plus nimotuzumab for 2 cycles and then received radical surgery or radiotherapy based on the efficacy assessed by investigators per RECIST v1.1.
