Brief Summary

This is a randomized Phase II trial to study the effectiveness and toxicity of neoadjuvant and adjuvant PD-1 antibody Toripalimab combined with concurrent cisplatin chemoradiotherapy versus cisplatin concurrent chemoradiotherapy plus placebo in treating patients with high risk locoregionally advanced nasopharyngeal carcinoma.

Detailed Description

Nasopharyngeal carcinoma (NPC) is endemic in Southern China and Southeast Asia. For locoregionally advanced NPC, especially for the high risk NPC (plasma EBV DNA ≥ 1500 copies/ml), the incidence of treatment failure is still high. Although concurrent chemoradiotherapy (CCRT) can improve the treatment outcomes of these patients, approximately 25% of locoregionally advanced NPCs still develop relapse and metastasis.

Hence, there is an urgent need for novel therapies to improve survival and reduce treatment-related toxicity in NPC patients. Accumulating evidence shows that PD-1 antibody is effective for treating recurrent/metastastic NPC patients. This is a Phase II randomized trial to study the effectiveness and toxicity of neoadjuvant and adjuvant PD-1 antibody Toripalimab combined with CCRT versus CCRT plus placebo in treating patients with high risk NPC (Stage III-IVa, AJCC 8th and EBV DNA ≥ 1500 copies/ml).
