Maintenance Therapy With Toripalimab and Capecitabine Versus Capecitabine Alone in High-risk Nasopharyngeal Carcinoma

Phase 3

Recruiting

• Conditions: High-Risk Cancer; Nasopharyngeal Carcinoma; Maintenance Therapy
• Interventions: Drug: Maintenance Therapy with Toripalimab and Capecitabine; Drug: Maintenance Therapy with Capecitabine

• Registration Number: NCT06277050
• Lead Sponsor: Jiangxi Provincial Cancer Hospital

Brief Summary

N3 classification, rENE positivity is a high-risk type of locally advanced nasopharyngeal carcinoma. EBV DNA remaining at detectable levels after induction chemotherapy is also a characteristic of high-risk nasopharyngeal carcinoma. Based on the available evidence, patients with high-risk nasopharyngeal carcinoma are recommended to receive oral maintenance therapy to reduce the risk of failure.

The purpose of this study was to conduct a prospective, multicenter, randomized phase III clinical trial to determine whether maintenance therapy with triprilimab combined with capecitabine is better than maintenance therapy with capecitabine alone in high-risk nasopharyngeal carcinoma (N3+, rENE+, Detectable EBV DNA after 2 cycles of induction chemotherapy).

Detailed Description

The study randomly divided these three types of high-risk nasopharyngeal carcinoma into two groups. The experimental group received maintenance therapy with toripalimab and capecitabine, while the control group received maintenance therapy with capecitabine alone. The maintenance treatment period of the two groups was 1 year.
