A Study Comparing of P-GEMD Regimen Versus P-Gemox Regimen With Untreated Early-Stage NUAT or Advanced-Stage ENKTL.

This Multicenter, Randomized Controlled Clinical Study aimed to compare the efficacy and safety of P-GEMD and P-Gemox in the treatment of newly diagnosed early NUAT or advanced-stage ENKTL. The P-GEMD regimen (pegaspargase; gemcitabine; etoposide; mitoxantrone hydrochlorid liposome; dexamethasone) was administered intravenously every 3 weeks until up to 6 cycles of planned therapy. The P-Gemox regimen ( Pegaspargase, Gemcitabine, and Oxaliplatin) was administered intravenously 3 weeks until up to 6 cycles of planned therapy.
