Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A prospective, open-abel, phase 2 clinical study to investigate whether interim Positron Emission Tomography (PET) and Epstein-Barr virus (EBV) DNA-directed therapy can improve the prognosis of localized nasal extranodal NK/T cell lymphoma (ENKTL) patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study aims to evaluate the significance of mid-term PET and EBV DNA-directed therapy for localized nasal ENKTL. Patients receive 2 cycles of ESA (Pegaspargase, Etoposide, Dexamethasone) regimen, then according to the mid-term PET and EBV DNA results, patients are divided into three cohorts: 1) cohort A: patients with Deauville score 1-3 and EBV DNA negative receive sequential radiotherapy and 2 cycles of ESA regimen; 2) cohort B: patients with Deauville score 1-3 and EBV DNA positive receive sequential radiotherapy and 2 cycles of PD-1 monoclonal antibody combined with pegaspargase; 3) cohort C: patients with Deauville score 4-5 receive 2 cycles of PD-1 monoclonal antibody and concurrent radiotherapy, then 2 cycles of PD-1 monoclonal antibody combined with pegaspargase.

Interim PET and EBV DNA-directed therapy

According to the interim PET and EBV DNA results, patients are divided into three cohorts: 1) cohort A: Deauville score 1-3 and EBV DNA negativity; 2) cohort B: Deauville score 1-3 and EBV DNA positivity; 3) cohort C: Deauville score 4-5.
