PD-1 Antibody-based Therapy With Concurrent RT for Early-stage NKTCL

Brief Summary
Natural killer/T-cell lymphoma (nasal type) is a mature T/NK-cell lymphoma closely associated with Epstein-Barr virus (EBV), with a high prevalence among populations in Asia and South America. It primarily occurs at extranodal sites, including the nasal/paranasal regions, skin, gastrointestinal tract, and other organs. This study focuses on previously untreated patients with early-stage NKTCL (nasal type), exploring a response-adapted comprehensive therapeutic strategy that combines PD-1 monoclonal antibody-based stratified targeted therapy with concurrent radiotherapy. The aim is to provide integrated management for early-stage extranodal NK/T-cell lymphoma (nasal type), and reduce toxicity while improving overall treatment outcomes for patients.

Conditions
Outcome Measures
Primary Outcomes (1)
2-year progression-free survival rate
Progression-free survival is defined as the time from registration to the first occurrence of disease progression or relapse, using 2014 Lugano criteria, or death from any cause. For patients who received subsequent treatment after the interim assessment, the endpoint shall be defined by the event first occurring after the initiation of subsequent treatment.
Baseline up to data cut-off (up to 24 months).
Secondary Outcomes (7)
Complete Response Rate
At the end of cycle 3, cycle 6 after treatment start.
Overall Response Rate
At the end of cycle 3, cycle 6 after treatment start.
2-year overall survival rate
Baseline up to data cut-off (up to 24 months).
2-year event-free survival rate
Baseline up to data cut-off (up to 24 months).
Duration of Response
From enrollment to study completion (up to approximately 24 months).
- +2 more secondary outcomes
Study Arms (2)
PD-1 antibody monotherapy group
EXPERIMENTALPatients will receive concurrent standard involved-site radiotherapy (ISRT) and PD-1 monoclonal antibody therapy. Administration of PD-1 mAb will start on Day 1 of radiotherapy (C1D1) at a dose of 200 mg via intravenous infusion over 30 minutes or longer, once every 3 weeks. After the 3rd cycle, patients will undergo re-evaluation (PET scan and plasma EBV DNA detection). Patients with an interim Deauville score of 1-3 and negative EBV DNA will continue to receive 3 cycles of PD-1 monoclonal antibody therapy.
The multi-drug combination group
EXPERIMENTALPatients will receive concurrent standard involved-site radiotherapy (ISRT) and PD-1 monoclonal antibody therapy. Administration of PD-1 mAb will start on Day 1 of radiotherapy (C1D1) at a dose of 200 mg via intravenous infusion over 30 minutes or longer, once every 3 weeks. After the 3rd cycle, patients will undergo re-evaluation (PET scan and plasma EBV DNA detection). Patients with an interim Deauville score of 4-5 or positive EBV DNA will subsequently receive 3 cycles of a combination regimen of PD-1 antibody, chidamide and golidocitinib.
Interventions
Concurrent standard involved-site radiotherapy (ISRT)
The dosage of chidamide will follow a dose-escalation design: 20 mg twice weekly (biw) in the first stage, then escalated to 30 mg biw, using the Bayesian Optimal Interval (BOIN) design to determine the recommended dose, followed by dose expansion in the second stage, every 3 weeks, cycle 4 - cycle 6.
Golidocitinib will be administered at a dose of 150 mg once daily (qd), every 3 weeks, cycle 4 - cycle 6.
Administration of PD-1 mAb will start on Day 1 of radiotherapy (C1D1) at a dose of 200 mg via intravenous infusion over 30 minutes or longer, once every 3 weeks, cycle 1 - cycle 6

- +4 more criteria
You may not qualify if:
- Advanced-stage disease (Ann Arbor Stage III-IV).
- Nonnasal-type NKTCL.
- A history of autoimmune disease requiring systemic treatment (i.e., with disease-modifying antirheumatic drugs, corticosteroids, or immunosuppressants) within the past 2 years, including but not limited to myasthenia gravis, myositis, autoimmune hepatitis, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, antiphospholipid antibody-associated vasculopathy, granulomatosis with polyangiitis (Wegener's), Sjögren's syndrome, Guillain-Barré syndrome, multiple sclerosis, vasculitis, or glomerulonephritis.
- The following conditions are permissible for enrollment: patients with autoimmune hypothyroidism or type 1 diabetes receiving stable treatment; hormone replacement therapy (e.g., levothyroxine, insulin, or supplementation with physiological hormones for adrenal or pituitary insufficiency) is not considered systemic therapy and is allowed.
- A history of other invasive malignancies within the past 3 years that has not been treated with curative intent or is currently receiving anticancer therapy (including hormonal therapy for breast or prostate cancer).
