PD-1 Inhibitor Plus G-CSF in Recurrent/Metastatic NPC With First-line Treatment Failure

NCT05222035 · Status: UNKNOWN · Phase: PHASE2 · Type: INTERVENTIONAL · Enrollment: 68

No results posted yet for this study

Summary

Recurrence and metastasis are the main causes of treatment failure of NPC. Preliminary clinical studies have found that the overall response rate of PD-1 inhibitors in treating ≥2 line R/M NPC is about 25%.

Recent studies have shown that G-CSF can significantly increase the proportion of effector cells dominated by CD4+ T cells, improve the diversity of peripheral blood TCR, and regulate the immune status of patients. Therefore, we suspect that G-CSF may have a synergistic effect on PD-1 inhibitor, thus enhance the efficacy of PD-1 inhibitor monotherapy.
