Two Cycles Versus Three Cyclle of CCRT for Low Risk Locoregionally Advanced Nasopharyngeal Carcinoma

A Randomized Phase II Non-inferiority Study of Two Cycles Versus Three Cycles of Cisplatin Based Concurrent Chemoradiotherapy for Low Risk Locoregionally Advanced Nasopharyngeal Carcinoma Based on Pretreatment Plasma EBV DNA Level

This is a Phase II trial to study the effectiveness of two cycles versus three cycles of Concurrent Chemoradiotherapy in treating patients with Low Risk Locoregionally Advanced Nasopharyngeal Carcinoma based on pretreatment plasma EBV DNA.

Study Overview

• Status: Unknown
• Conditions: Nasopharyngeal Carcinoma
• Intervention / Treatment: Drug: Cisplatin combine with IMRT; Drug: Cisplatin combine with IMRT

Detailed Description

Nasopharyngeal carcinoma (NPC) is endemic in Southern China and Southeast Asia. Several prospective randomized trials have demonstrated that concurrent chemoradiotherapy was superior to radiotherapy alone in the treatment of locoregionally advanced NPC. Concurrently, although cisplatin-based concurrent chemoradiotherapy was considered as the standard regimen for locoregionally advanced nasopharyngeal carcinoma, several prospective randomized trials have demonstrated that only 52-63% patients can finished three cycles cisplatin-based concurrent chemoradiotherapy( DDP, 100mg/m2,D1,D22 and D43), due to chemoradiotherapy induced toxicity. Combined analyses of NPC-9901 and NPC-9902 Trials indicated that the 5-year locoregional failure free survival was insignificant between the patients received between two and three cycles cisplatin-based concurrent chemoradiotherapy. Our previous studies have also demonstrated that the five years overall survival, distant metastasis free survival and 5-year locoregional failure free survival was not observed significant difference between the patients received between two and three cycles cisplatin-based concurrent chemotherapy. It indicated that one pressing questions remain to be resolved: can we define the optimal dose so that we can reduce toxicity by avoiding unnecessary overdose or an ineffective phase of treatment? Recently, the quantification of pretreatment plasma Epstein-Barr virus (EBV) DNA, which was considered the most potential biomarker to compliment TNM stage, was demonstrated a useful biomarker for the risk stratification, monitoring and prediction of the prognosis of NPC. The investigators previous study demonstrated that for local and regionally advanced NPC patients with EBV DNA <4,000copies/mL, the 3-year's PFS and DMFS was approximate to 90%. Pretreatment plasma EBV DNA levels might be applied to guide concurrent chemotherapy regimen for local and regionally advanced NPC patients. Therefore, the investigators make a hypothesis that the low risk locoregionally advanced NPC patients received two cycles of chemotherapy may gain similar long-term survival as those received three cycles of chemotherapy, leading to less chemotherapy induced toxicity. Therefore, this phase II non-inferiority, randomised controlled clinical trial was designed to assess efficacy for low-risk patients, identified with pretreatment plasma EBV DNA <4,000 copies/mL, received two cycle cisplatin-based chemotherapy compared with three cycle cisplatin-based chemotherapy

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progress-free survival	Progress-free survival is calculated from the date of randomization to the date of the first progress at any site or death from any cause or censored at the date of the last follow-up	3 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The shor-term toxic effects	The shorterm toxic effects were assessed by the National Cancer Institute Common Terminology Criteria for Adverse Events (version 4.0)	3 months
Complete Response (CR)	CR assessed by independent reviewers, according to the Modified Response Evaluation Criteria in Solid Tumors (RECIST) from the National Cancer Institute (NCI). Disease response evaluated after the completion of the chemoradiotherapy treatment. Complete response defined as the complete disappearance of the target and non-target lesion(s) identified at baseline after radiological evaluation by Magnetic Resonance Imaging (MRI) only	after the completion of the chemoradiotherapy treatment (up to 9 weeks)
Overall Survival(OS)	The OS was defined as the duration from the date of random assignment to the date of death from any cause or censored at the date of the last follow-up	3 years
Locoregional Relapse-Free Survival(LRRFS)	The LRRFS is evaluated and calculated from the date of random assignment until the day of first locoregional relapse or until the date of the last follow-up visit	3 years
Distant Metastasis-Free Survival (DMFS)	The DMFS is evaluated and calculated from the date of random assignment until the day of first distant metastases or until the date of the last follow-up visit	3 years
Cost-effectiveness analysis	The cost (including direct cost drug fees, inspection fees, expenses and nursing cost) and incremental cost-effectiveness ratio was calculated between two arms	3 years
The monitoring of plasma EBV DNA	The plasma EBV DNA will be detected before treatment ,during treatment (weekly) and during follow up( every 3-6 months)	3 years
Long-term toxicities	Patients will be monitored for long-term toxicity by standard NIH criteria. QoL was assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTCQLQ-C30) and EORTC QLQ Head and Neck	3 years
