About this trial
This multicenter, open-label, randomized Phase III trial evaluates intensity-modulated proton therapy (IMPT) versus intensity-modulated photon radiotherapy (IMRT) in patients with newly diagnosed, high-risk, locoregionally advanced nasopharyngeal carcinoma.
All patients receive induction chemotherapy followed by concurrent chemoradiotherapy combined with immunotherapy and are randomized 1:1 to IMPT or IMRT during the concurrent treatment phase.
The primary endpoints are the incidence of grade ≥3 acute treatment-related toxicities and the 3-year progression-free survival (PFS) rate. Secondary endpoints include overall survival, locoregional relapse-free survival, distant metastasis-free survival, objective response rate, late toxicities, and quality of life.
