Phase III Trial of Concurrent Chemotherapy Alone in Patients With Low-risk Nasopharyngeal Carcinoma

Phase 3
Recruiting
Conditions
Nasopharyngeal Carcinoma
Interventions
Radiation: IMRT and concurrent cisplatin
Registration Number
NCT05979961
Lead Sponsor
Sun Yat-sen University
Brief Summary

The purpose of this study is to compare concurrent chemoradiotherapy (CCRT) alone with induction chemotherapy (gemcitabine+cisplatin) plus CCRT in patients with low-risk locoregionally advanced nasopharyngeal carcinoma(NPC).

Detailed Description

Patients with low risk NPC( Stage III-IVa, except T4N2/AnyTN3, AJCC 8th and EBV DNA \<4000 copies/ml) are randomly assigned to receive CCRT alone or induction chemotherapy plus CCRT. Patients in both groups receive cisplatin 100 mg/m² every 3 weeks for 3 cycles, concurrently with intensity-modulated radiotherapy (IMRT). IMRT is given as 2.12 Gy per fraction with five daily fractions per week to a total dose of 70 Gy. The induction chemotherapy plus CCRT group receive gemcitabine (1000 mg/m² d1,8) and cisplatin (80mg/m² d1) every 3 weeks for three cycles before CCRT. Our primary endpoint is progress-free survival. Secondary end points include overall survival (OS), Locoregional progression, Distant progression and toxic effects. All efficacy analyses are conducted in the intention-to-treat population, and the safety population include only patients who receive their randomly assigned treatment.

IMRT and concurrent cisplatinIMRT and concurrent cisplatinPatients receive intensity modulated-radiotherapy (IMRT), concurrently with cisplatin 100 mg/m² every 3 weeks for 3 cycles.
Induction chemotherapy+IMRT and concurrent cisplatinIMRT and concurrent cisplatinPatients receive gemcitabine (1000 mg/m² d1,8) and cisplatin (80mg/m² d1) every 3 weeks for 3 cycles before radiotherapy, and then receive intensity modulated-radiotherapy (IMRT), concurrently with cisplatin 100 mg/m² every 3 weeks for 3 cycles.

Primary Outcome Measures
NameTimeMethod
Progress-free survival(PFS)3 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 response rate16 weeks after completion of concurrent chemoradiotherapy

Tumour response was classified according to RECIST, version 1.1

Overall survival(OS)3 years

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

Locoregional progression3 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).

Incidence of acute and late toxicity3 years

Incidence of acute toxicity is calculated for each adverse event respectively and severity 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.

Distant progression3 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).
