About

This is a phase 3, multicentre, randomised controlled trial to study the effectiveness and toxicity of PD-1 antibody Toripalimab combined with concurrent cisplatin chemoradiotherapy versus cisplatin concurrent chemoradiotherapy alone in treating patients with locoregionally recurrent nasopharyngeal carcinoma.

Full description

Nasopharyngeal carcinoma (NPC) is endemic in southern China, southeast Asia, and northern Africa. According to a survey from the International Agency for Research on Cancer, there were an estimated 129,079 new cases and 72,987 related deaths in 2018. Radiotherapy is the primary treatment option. Due to advances in disease management, diagnostic imaging, radiotherapy technology, and the broader application of systemic therapy, the prognosis of NPC has improved signifificantly.Nevertheless, localregional recurrence will occur in about 10% patients. Because of radiation resistance, the prognosis of re-irradiation is poor for recurrent nasopharyngeal carcinoma.

Hence, there is an urgent need for novel therapies to improve survival and reduce treatment-related toxicity in recurrent NPC patients. Emerging evidence shows that PD-1 antibody is effective for treating recurrent/metastastic NPC patients. This is a phase 3, multicentre, randomised controlled trial to study the effectiveness and toxicity of neoadjuvant and adjuvant PD-1 antibody Toripalimab combined with concurrent chemoradiotherapy (CCRT) versus CCRT alone in treating patients with locoregionally recurrent nasopharyngeal carcinoma.
