Intensified Treatments for Patients With Locally Advanced Nasopharyngeal Carcinoma With Detectable EBV DNA After One Cycle GP Regime Neoadjuvant Chemotherapy

Overview

The goal of this multicenter randomized non-inferior study is to compare the additon of camrelizumab or nimotuzumab to neoadjuvant chemotherapy followed by concurrent chemoradiotherapy in locally advanced nasopharyngeal carcinoma patients whose EBV DNA remained detectable after one cycle neoadjuvant chemotherapy using GP regimen. The main question it aims to answer is: whether the addition of carrilizumab or nituzumab improve the treatment outcomes in the relatively poor prognostic patients identified by the response of EBV DNA. Participants will be randomized to the combination of carrilizumab and standard treatment , the combination of nituzumab and standard treatment or the standard treatment alone if their EBV DNA didn't decrease to undetectable level post first cycle of neoadjuvant chemotherapy.
