Sintilimab Combination Therapy Plus IMRT in Nasopharyngeal Carcinoma

Status Not yet recruiting

Clinical Trial Summary

This is a prospective, single-center, single-arm, phase II clinical study. The study was intended to include patients with locoregionally advanced nasopharyngeal cancer identified by histology or cytology, who signed informed consent and met the screening criteria to enter the study. Patients will receive induction therapy (sintilimab + bevacizumab + gemcitabine, Q3W, 3 cycles) followed by IMRT+ Sintilimab. Consolidation therapy with sintilimab continued after radiotherapy until disease progression, intolerable toxicity, death, or the subject's decision to withdraw from the study, with a total treatment period of no more than 12 cycles.

Clinical Trial Description

Platinum deplatinization has been extensively explored in patients with posterior nasopharyngeal carcinoma who have received multiple platinum treatments, including target-free combination, GEP, etc. Our center also published in 2022 CSCO a study on the preliminary efficacy of pembrolizumab combined with gemcitabine in the first-line treatment of metastatic NPC with or without cisplatin or anlotinib. Enrolled patients were treated with pembrolizumab + anlotinib +GP (group A), pembrolizumab +GP (group B), and pembrolizumab + anlotinib +G (group C), with ORR of 80% (4/5), 80% (4/5), and 100% (7/7), respectively. Among them, there were 1 CR and 6 PR in group C. Compared to group B, group C with anlotinib in place of cisplatin showed a better safety profile with fewer grade 3 adverse reactions (57.1% vs 100%). In summary, we designed this study to evaluate the efficacy and safety of gemcitabine, sintilimab and bevacizumab combined with IMRT in patients with advanced nasopharyngeal carcinoma not suitable for platinum-based treatment, and to explore new therapeutic approaches for patients with advanced stage nasopharyngeal carcinoma who cannot tolerate platinum therapy or are unwilling to receive platinum therapy. This is a prospective, single-center, single-arm, phase II clinical study. The study was intended to include patients with locoregionally advanced nasopharyngeal cancer identified by histology or cytology, who signed informed consent and met the screening criteria to enter the study. Patients will receive induction therapy (sintilimab + bevacizumab + gemcitabine, Q3W, 3 cycles) followed by IMRT+ Sintilimab. Consolidation therapy with sintilimab continued after radiotherapy until disease progression, intolerable toxicity, death, or the subject's decision to withdraw from the study, with a total treatment period of no more than 12 cycles. ;
