Interventions
N-803 Subcutaneous (SQ): N-803 is a novel IL-15 superagonist immunotherapy administered subcutaneously. It is designed to enhance the proliferation and activation of natural killer (NK) cells and CD8+ T cells without stimulating regulatory T cells. N-803 SQ differs from other cytokine therapies due to its improved pharmacokinetic profile, enhanced in vivo activity, and reduced toxicity. CD19-Directed Therapies: CD19-targeted therapies, are biologic agents specifically designed to recognize and eliminate CD19-expressing B-cell malignancies. These therapies differ from traditional chemotherapy or small molecule inhibitors by leveraging the patient's immune system to achieve targeted cytotoxicity. Their mechanism of action involves direct binding to the CD19 antigen on malignant B cells, leading to immune-mediated cell death.
Eligibility Criteria
You may qualify if:
- Age\>18 years old 2- Able to understand and provide a signed informed consent that fulfills the relevant Human Research Ethics Committee( HRECC) or independent Ethics Committee( IEC) guidelines 3. Histologically or flow cytometry documented B-cell NHL, (excluding primary central nervous system \[CNS\] lymphoma, chronic lymphocytic leukemia \[CLL\], and Burkitt lymphoma) with the following specific criteria:
- Have completed ≥2 lines of cytotoxic chemotherapy.
- Have received rituximab or another anti-CD20 antibody.
- Have measurable disease by Lugano classification documented within 8 weeks of the time of consent, defined as nodal lesions \>15 mm in the long axis or extranodal lesions \>10 mm in long and short axis, or bone marrow involvement that is biopsy proven.
- \. Eastern Cooperative Oncology Group (ECOG) performance status (Appendix 5) of 0 to 1.
- \. Stated willingness to comply with study procedures. 6. Able to attend required study visits and return for adequate follow-up, as required by this protocol.
- \. Agreement to practice effective contraception for female participants of childbearing potential and nonsterile males. Female participants of childbearing potential must agree to use effective contraception while on study and for at least 30 days after the last dose of study drug. Nonsterile male participants must agree to use a condom while on study and for up to 30 days after the last dose of study drug. Effective contraception includes orals, injectables, surgical sterilization (e.g., vasectomy, tubal ligation), two forms of barrier methods (e.g., condom, diaphragm) and implants such as intrauterine devices (IUDs).
You may not qualify if:
- Participants with ANY of the following criteria are excluded from participation in the study:
- Histologically documented primary CNS lymphoma, CLL, Burkitt, Burkitt-like lymphoma.
- Known hypersensitivity or allergy to any component of the study medications, including sulfa-containing study medication(s) (e.g., albumin \[human\], dimethyl sulfoxide \[DMSO\]).
- Inadequate organ function, evidenced by the following laboratory results:
- ANC \< 1000 cells/mm3.
- Platelet count \< 100,000 cells/mm3.
- Total bilirubin ≥ 1.5 × the upper limit of normal (ULN; unless the participant has documented Gilbert's syndrome or indirect hyperbilirubinemia).
- Aspartate aminotransferase (AST \[SGOT\])/ALT (SGPT) ≥ 2.5 × ULN.
- Alkaline phosphatase (ALP) levels ≥ 2.5 × ULN (or ≥ 5 × ULN in participants with bone metastases).
- Serum creatinine ≥ 160 µmol/L. NOTE: Each study site should use its institutional ULN to determine eligibility.
- Serious uncontrolled concomitant disease that would contraindicate the use of the investigational drug used in this study or that would put the participant at high risk for treatment-related complications.
- History of significant autoimmune disease OR active, uncontrolled autoimmune phenomenon: such as systemic lupus erythematous, Wegner's glomerulonephritis, autoimmune hemolytic anemia, idiopathic thrombocytopenic purpura requiring steroid therapy defined as \> 20 mg of prednisone or equivalent daily.
- History of allogeneic hematopoietic stem-cell transplantation (HSCT) requiring ongoing systemic graft versus host disease (GvHD) therapy.
- Anti-CD20 antibody treatment less than 2 weeks prior to cell infusion.
- History of receiving allograft organ transplant requiring immunosuppression.
