Study Details

Study Description

Brief Summary

The program aims to enroll patients with stage high risk (AJCC 8th, T3-4N2-3M0) . Patients will receive 3 cycles of induction chemotherapy with gemcitabine and cisplatin and concurrent cisplatin-radiation plus Sintilimab, and then receive 11 cycles of Sintilimab after intensity-modulated radiotherapy (IMRT). All patients will receive IMRT. Sintilimab will begin on day 1 of induction chemotherapy and continue every 3 weeks for 17 cycles.

Detailed Description

The program aims to enroll patients with stage high risk (AJCC 8th, T3-4N2-3M0) locoregionally advanced nasopharyngeal carcinoma (LANPC). Patients will receive 3 cycles of induction chemotherapy with gemcitabine and cisplatin and concurrent cisplatin-radiation plus Sintilimab (200mg q3wk), and then receive 11 cycles of Sintilimab after intensity-modulated radiotherapy (IMRT). All patients will receive IMRT. IMRT：PGTVnx: 69.96 Gy /33f, PGTVnd: 66_{70 Gy /33f, PCTVnd: 63}64 Gy/33f, PCTV1: 60_{62 Gy/33f, PCTV2: 54}56 Gy/33f. Sintilimab will begin on day 1 of induction chemotherapy and continue every 3 weeks for 17 cycles.

Outcome Measures

Primary Outcome Measures

Progress-free survival (PFS) [5 years]
Defined from date of recruit to date of first documentation of progression or death due to any cause.

Secondary Outcome Measures

Overall Survival (OS) [5 years]
Defined from date of recruit to date of first documentation of death from any cause or censored at the date of the last follow-up.
Locoregional Relapse-Free Survival (LRRFS) [5 years]
Defined from date of recruit to date of first documentation of locoregional relapse or until the date of the last follow-up visit.
Distant Metastasis-Free Survival (DMFS) [5 years]
Defined from date of recruit to date of first documentation of distant metastases or until the date of the last followup visit.
Objective Response Rate （ORR） [through study completion, an average of 1 year]
An objective response is defined as either a confirmed CR or a PR, as determined by the investigator using RECIST v1.1Response Evaluation Criteria in Solid Tumors (RECIST) from the National Cancer Institute (NCI).
Incidence rate of adverse events (AEs) [5 years]
Analysis of adverse events (AEs) are based on treatment-related AEs (trAEs) and immune-related AEs (irAEs), and all-grade AEs and grade 3-4 AEs. AEs are evaluated by investigators according to the Common Terminology Criteria for Adverse Events, version 5.0
Serious adverse events (SAE) [5 years]
Serious adverse events (SAE) is defined as either death, life-threatening, or Permanent or severe disability/incapacity.
