TPC Versus GP Induction Chemotherapy for Nasopharyngeal Carcinoma

Phase 2
Recruiting
Conditions
Nasopharyngeal Carcinoma
Interventions
Drug: GP induction chemotherapy
Drug: TPC induction chemotherapy
Registration Number
NCT06301165
Lead Sponsor
Sun Yat-sen University
Brief Summary

The NCCN guidelines recommend induction chemotherapy followed by concurrent chemoradiotherapy as the standard treatment for locoregionally advanced nasopharyngeal carcinoma (NPC). However, meta-analyses have shown significant survival differences between different induction chemotherapy regimens. How to choose an induction chemotherapy regimen and treatment course that ensures definitive therapeutic effects and low incidence of toxic side effects remains a hot spot in clinical research. Polymeric micellar paclitaxel are an innovative form of paclitaxel drugs, with high penetration and long retention effects, which can enter the vascularly disordered tumor microenvironment through passive targeting and form higher concentrations in tumor tissue. It remains to be investigated whether the TPC (paclitaxel, cisplatin and capecitabine) regimen based on polymeric micellar paclitaxel compared to the current standard first-line induction chemotherapy GP (gemcitabine, cisplatin) regimen can further improve therapeutic effects in high-risk patients with locally advanced disease. There is still a lack of head-to-head studies for comparison. This study aims to compare, through a prospective, parallel-controlled, randomized, open-label, multicenter phase II clinical trial, the TPC induction chemotherapy vs. the GP induction chemotherapy combined with concurrent chemoradiotherapy for the treatment of high-risk locoregionally advanced NPC (T4 or N2-3) in terms of 2-year progression-free survival, overall survival, overall response rate, toxic side effects, etc.

Primary Outcome Measures
NameTimeMethod
Progression-free survival2 years

Defined as the time from random assignment to documented local or regional relapse, distant metastasis, or death from any cause, whichever occurred first.

Secondary Outcome Measures
NameTimeMethod
Overall survival2 years

Defined as the time from random assignment to death from any cause.

Short-term response rate32 weeks

Tumour response was classified according to RECIST, version 1.1

Locoregional progression2 years

Defined as the time from random assignment to the occurrence of a locoregional progression. Cumulative incidence of locoregional progression will be calculated within a competing risk framework (Fine and Gray 1999).

Distant progression2 years

Defined as the time from random assignment to the occurrence of a distant progression. Cumulative incidence of distant progression will be calculated within a competing risk framework (Fine and Gray 1999).

Incidence of acute and late toxicity2 years

Incidence of acute toxicity is evaluated on basis of Common Terminology Criteria for Adverse Events (CTCAE) 5.0 criteria. Late radiation toxicities were assessed using the Radiation Therapy Oncology Group and European Organization for Research and Treatment of Cancer late radiation morbidity scoring scheme. Acute adverse events, occurring during study treatment, and radiation-related late adverse events, occurring from 3 months after completion of radiotherapy, and chemotherapy-induced late adverse events, occurring from 3 months after completion of chemotherapy until end of follow up).
