Summary
Brief summary (as posted)
In this study the investigators investigate a cell therapy strategy that could harness allogeneic effectors that can potentially mediate anti-lymphoma effect. The investigators have designed a novel lymphodepleting conditioning regimen followed by infusion of donor-derived natural killer (NK) cells and interleukin-2 (IL-2) for patients with refractory lymphoid malignancies.

- description
- The number of patients with a partial response (PR) or complete response (CR). For patients with non-hodgkin's lymphoma: CR - complete disappearance of all detectable clinical evidence of disease and disease-related symptoms. PR - at least a 50% decrease in sum of the product of the diameters of up to six of the largest dominant nodes or nodal masses. For patients with chronic lymphocytic leukemia: CR - disappearance of all palpable disease, normalization of the blood counts without transfusions, bone marrow aspirate lymphocyte percentage \< 30%, and no evidence of disease on bone marrow biopsy. PR - 50% or more reduction in palpable disease as well as one or more of the remaining features: neutrophils \>= 1.5 × 109/L or 50% improvement over baseline, platelets more than 100 × 109/L or 50% improvement over baseline, and hemoglobin more than 11.0 g/dL or 50% improvement over baseline without transfusions.

Inclusion Criteria: * Patients of any age with diagnosis of: * Relapsed/refractory lymphoma (B cell non-Hodgkin) who have lack of objective response to at least two prior chemotherapy regimens * Relapsed chronic lymphocytic leukemia with high risk features: lack of objective response or relapse within 6 months following nucleoside-analogue based chemotherapy regimen or patients with 17p deletion CLL who lacked objective response to at least 1 preceding chemotherapy regimen * Available related HLA haploidentical NK cell donor by at least Class I serologic typing at the A\&B locus (age 12-75 years) * Karnofsky \> 70% for patients 16 years and older and Lansky play score \> 50 for patients under 16 years of age * Measurable disease based on modified Response Evaluation Criteria in Solid Tumors (RECIST) * Have acceptable organ function as defined within 28 days of enrollment: * Hematologic: platelets ≥ 80,000 x 10\^9/L; hemoglobin ≥ 9 g/dL, unsupported by transfusions within 7 days; absolute neutrophile count (ANC) ≥ 1000 x 10\^9/L, unsupported by Granulocyte colony-stimulating factor (G-CSF) or Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF) for 10 days or Neulasta for 21 days - the hematologic requirements are waived for patients with inadequate counts due to known bone marrow involvement by disease who are otherwise eligible * Renal: calculated glomerular filtration rate (GFR) \> 50 ml/min * Hepatic: Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) \< 5 x upper limit of normal and total bilirubin ≤3 mg/dl - hepatic requirements are waived for patients with known disease involvement in the liver if otherwise eligible * Pulmonary function: \>40% corrected Carbon Monoxide Diffusing Capacity (DLCO) and Forced expiratory volume in one second (FEV1) (oxygen saturation \[\>92%\] can be used in child where pulmonary function tests (PFT's) cannot be obtained) * Cardiac: no symptoms of uncontrolled cardiac disease, left ventricular ejection fraction ≥ 40% * Able to be off prednisone or other immunosuppressive medications for at least 3 day prior to Day 0 (excluding denileukin diftitox pre-medications) * Sexually active women of childbearing potential must agree to use adequate contraception (diaphragm, birth control pills, injections, intrauterine device \[IUD\], surgical sterilization, subcutaneous implants, or abstinence, etc.) for the duration of treatment. * Voluntary written consent Exclusion Criteria: * Pregnant or lactating. The agents used in this study may be teratogenic to a fetus and there is no information on the excretion of agents into breast milk. All females of childbearing potential must have a blood test or urine study within 14 days prior to enrollment to rule out pregnancy. Women of childbearing age must use appropriate contraceptive method. * Active central nervous system (CNS) lymphoma/leukemia - Patients with prior CNS involvement are eligible provided that it has been treated and is in remission. * Active serious infection (pulmonary infiltrates or lesions are allowed only after the appropriate diagnostic testing is negative for infection or appropriate therapy was initiated for probable infection) * Pleural effusion large enough to be detectable on chest x-ray (CXR) * Evidence of human immunodeficiency virus (HIV) infection or known HIV positive serology * Active concurrent malignancy (except skin cancer) * Epstein-Barr virus (EBV) post-transplant lymphoproliferative disorder * Positive HBsAg. If HBcAb is positive, Hepatitis B DNA by PCR will be evaluated. Positive anti HBcAb with an undetectable viral load does not exclude the patient. * Any investigational therapy in the past 30 days * Patients following allogeneic stem cell transplantation are eligible in the absence of graft versus host disease and are off immunosuppression for at least 30 days * Known allergy to any of the study agents
