Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

More and more studies have shown that the efficacy and prognosis of HPV （Human papillomavirus）-positive oropharyngeal cancer (OPC) patients are better than those of others. However, in the NCCN (National Comprehensive Cancer Network) Oncology Clinical Guidelines for OPC treatment, each group of p16+ is consistent with the corresponding group of p16-, which indicates that the treatment of OPC is basically the same regardless of whether it is related to HPV. Several studies attempted to reduce the toxicities of treatment of HPV related OPC through reduced-dose radiation and showed promising results, and all of the studies have shown that induction chemotherapy is a good way to screen followed treatment. Those who are effective in induction chemotherapy are usually more sensitive to radiation therapy, and reducing the intensity of subsequent treatment will not affect the survival outcome of patients. Immune checkpoint inhibitors (ICIs) have proved to improve outcomes of head and neck cancers. However, In KEYMAT-048, a Phase III controlled trial of relapsed/metastatic head and neck squamous cell carcinoma, ICIs showed an overall survival advantage, but the survival advantage was independent of HPV status. Therefore, patients with HPV-negative OPC still have a good response to ICIs. So we added anti-PD-1 antibody Toripalimab to induction chemotherapy in order to achieve better response rates to receive de-escalation chemoradiotherapy followed regardless of whether it is related to HPV.

Toxicities reduced treatment arm

Two cycles toripalimab+docetaxel+cisplatin+capecitabine (TPF) induction chemotherapy followed by reducing radiation dose(60Gy/30Fx) and omitting concurrent cisplatin chemotherapy when responses to induction chemotherapy are ≥ 70% Partial Response(PR) in HPV-related patients.

Two cycles toripalimab+docetaxel+cisplatin+capecitabine (TPF) induction chemotherapy followed by reducing radiation dose(60Gy/30Fx) combined with concurrent cisplatin chemotherapy when responses to induction chemotherapy are ≥ 70% Partial Response(PR) in HPV-urelated patients.
