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

Recruiting now · Phase 2

Conditions studied: Natural Killer/T-cell Lymphoma

In brief

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.

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).
A history of (non-infectious) pneumonia requiring corticosteroid therapy; or clinical evidence of interstitial lung disease or active, non-infectious pneumonia.
Active infections requiring systemic treatment, including:
A known history of active tuberculosis;
Positive results for HBsAg, HCV, or HIV; HBV seropositivity is permitted only if HBV DNA < 1000 IU/mL;
Active viral infections other than hepatitis B and C (e.g., herpes zoster).
Severe cardiovascular disease, including myocardial infarction, unstable arrhythmia, or unstable angina occurring within the past 3 months.
Prior treatment with anti-PD-1, anti-PD-L1, or anti-PD-L2 agents.
Administration of live-attenuated vaccines within 4 weeks prior to the initiation of study treatment; patients are prohibited from receiving live-attenuated vaccines during the study period, including influenza vaccines.
Use of systemic immunosuppressive agents within 2 weeks prior to the initiation of study treatment, or planned use of such agents during the study period, including cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-tumor necrosis factor (anti-TNF) drugs.
Evidence of central nervous system involvement.
A history of allogeneic tissue/solid organ transplantation.
A history of severe hypersensitivity reactions (Grade ≥ 3) to PD-1 monoclonal antibodies and/or their excipients, or to gorlitinib and/or its excipients.
Any other factors judged by the investigator to potentially affect compliance with the study protocol.
