Combining Pegaspargase and Chemotherapy with Radiotherapy for NK/T Cell Lymphoma

A Prospective Phase II Study of Pegaspargase-COEP Chemotherapy Combined With Radiotherapy for Patients With Newly Diagnosed Extra-nodal NK/T-cell Lymphoma

Phase 2 Interventional Peking University · NCT04484506

This study is testing a new treatment plan that combines chemotherapy and radiation for people who have just been diagnosed with extra-nodal NK/T-cell lymphoma to see if it works better than existing options.

What this trial studies

This phase II study evaluates the effectiveness and safety of a treatment regimen that includes pegaspargase, cyclophosphamide, vincristine, etoposide, and prednisone (COEPL) combined with radiotherapy for patients newly diagnosed with extra-nodal NK/T-cell lymphoma (ENKTL). The study aims to establish a more defined first-line treatment approach for this type of lymphoma, which currently lacks a well-defined standard. Participants will be monitored for treatment efficacy and safety throughout the study.

Who should consider this trial

Good fit: Ideal candidates are patients aged 14-80 with a confirmed diagnosis of ENKTL and no prior chemotherapy or radiotherapy.

Not a fit: Patients with central nervous system involvement, severe infections, or other significant health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a more effective first-line therapy for patients with extra-nodal NK/T-cell lymphoma.

How similar studies have performed: While this approach is being evaluated in this study, the combination of chemotherapy and radiotherapy has shown promise in other lymphoma treatments, suggesting potential for success.
