Brief Summary

The trial aimed to compare QL1706 combined with induction chemotherapy plus concurrent chemoradiotherapy (IC+CCRT) versus IC+CCRT alone in High-risk Locoregionally-Advanced Nasopharyngeal Carcinoma (LANPC).

Detailed Description

The trial plans to enroll patients with stage T4N1and T1-4N2-3 (AJCC 9th) locoregionally-advanced nasopharyngeal carcinoma (LANPC). Patients will be randomized in a 1:1 ratio to receive 3 cycles of induction chemotherapy with gemcitabine and cisplatin and concurrent cisplatin-radiation or the same regimen plus QL1706 in induction chemotherapy and adjuvant chemotherapy. All patients will receive intensity-modulated radiotherapy (IMRT). QL1706 will begin on day 1 of induction chemotherapy and continue every 3 weeks for 3 cycles in induction therapy and for 9 cycles in adjuvant therapy.

Primary Outcome Measures
NameTimeMethod
Failure-free survival (FFS) in intention-to-treat population3 years

Multiple endpoint 1: calculated from randomization to the date of locoregional recurrence, distant metastasis, or death from any cause, whichever occurred first.

Overall survival (OS) in intention-to-treat population5 years

Multiple endpoint 2: calculated from randomization to the date of death from any cause.

Secondary Outcome Measures
NameTimeMethod
Failure-free survival (FFS) in per-protocol population3 years

calculated from randomization to the date of locoregional recurrence, distant metastasis, or death from any cause, whichever occurred first.

Overall survival (OS) in per-protocol population3 years

calculated from randomization to the date of death from any cause.

Locoregional recurrence-free survival (LRRFS)3 years

calculated from randomization to the date of locoregional persistence or 1st locoregional recurrence.

Distant metastasis-free survival (DMFS)3 years

calculated from randomization to the date of first distant metastasis.

Adverse events (AEs) and serious adverse events (SAEs)3 years

Graded according to CTCAE V5.0.

Quality of life (QoL)week 1, 20, 40, 64

The change of QoL from randomization to the start of radiotherapy, the end of radiotherapy, 13-16 weeks after radiotherapy, 2 years and 3 years after randomization. The EORTC QoL questionnaire-C30 (EORTC QLQ-C30)version 3.0 will be used. This questionnaire comprises 30 questions, 24 of which are aggregated into nine multi-question scales, that is, five functioning scales (e.g., physical), three symptom scales (e.g., fatigue) and one global health status scale. The remaining six single-question (e.g., dyspnoea) scales assess symptoms. These 15 scales will be scored according to the official Scoring Manual.

Failure-free survival (FFS) within different subgroups3 years

analyses for FFS will be performed within the following subgroups: Epstein-Barr virus (EBV) DNA (≤4000copies/ml vs. \>4000copies/ml), different PD-L1 expression levels, age, gender, performance status, T category, N category, and stage (III vs. IVA).

Tumor responseEvery 6 weeks(the time of completion of induction chemotherapy, radiotherapy, and adjuvnt immunotherapy; from the date of enrollment until the date of the last time that tumorimaging and assessment of disease has been done, assessed up to 74 weeks)

Evaluation of tumor response as CR, PR, SD, PD, NA by clinicians
