Toripalimab Combined With Radiotherapy in the Treatment of Oligometastatic Nasopharyngeal Carcinoma

Phase 2

Recruiting

• Conditions: Nasopharyngeal Carcinoma
• Interventions: Drug: Toripalimab

• Registration Number: NCT05147844
• Lead Sponsor: Xinqiao Hospital of Chongqing

Brief Summary

The aim of the study was to determine the efficacy and safety of toripalimab combined with radiotherapy in the treatment of oligometastatic nasopharyngeal carcinoma

Detailed Description

Chemotherapy has been widely used for the treatment of relapsed or metastatic nasopharyngeal carcinoma. However, the long-term survival and quality of life of patients was still unsatisfactory. In this prospective, multicenter, single arm study, the efficacy and safety of toripalimab combined with radiotherapy in the treatment of oligometastatic nasopharyngeal carcinoma is determined.
