Nimotuzumab Combined With Radiotherapy in High-risk Patients With HNSCC Not Suitable for Cisplatin After Surgery

Study Overview
=================
Brief Summary
-----------------
This study is a prospective, open label, multicenter, randomized controlled clinical trial. The main purpose of the study is to evaluate the efficacy and safety of nimotuzumab combined with concurrent radiotherapy versus radiotherapy alone in high-risk patients with HNSCC not suitable for cisplatin after surgery. The subjects were randomly divided into study group (nimotuzumab combined with concurrent radiotherapy) and control group (radiotherapy alone) by 1∶1 stratified random method.

Detailed Description
-----------------
This study is a prospective, open label, multicenter, randomized controlled clinical trial. The main purpose of the study is to evaluate the efficacy and safety of nimotuzumab combined with concurrent radiotherapy versus radiotherapy alone in high-risk patients with HNSCC not suitable for cisplatin after surgery. The subjects were randomly divided into study group and control group by 1∶1 stratified random method. The study group received nimotuzumab (200mg, weekly, for 6 weeks) combined with concurrent radiotherapy, while the control group received radiotherapy alone. The main endpoint is 2 year disease free survival (DFS) rate.
