The purpose of this study is to find the number of natural killer (NK) cells from non-HLA matched donors that can be safely infused into patients with cancer. NK cells are a form of lymphocytes that defend against cancer cells. NK cells in cancer patients do not work well to fight cancer. In this study, the NK cells are being donated by healthy individuals without cancer who are not "matched" by human leukocyte antigen (HLA) genes to patients. After receiving these NK cells, patients may also be given a drug called ALT803. ALT803 is a protein that keeps NK cells alive, helps them grow in number and supports their cancer-fighting characteristics. HLA-unmatched NK cell infusion is investigational (experimental) because the process has not approved by the Food and Drug Administration (FDA).

Primary Objective:
To determine the maximum tolerated dose (MTD) of ex vivo expanded non-HLA matched donor NK cells in combination with ALT-803
Secondary Objectives:
Study Design:
This is a phase I study with "3+3" design with three planned dose levels of NK cells and a fixed dose of ALT-803. Three patients will be enrolled sequentially to each dose level, starting with dose level 1. Patients will be segregated to either receive ALT803 as cytokine support after NK cell infusion (starting with same dose level as Level 1) or no cytokine administration. Patients in the arm receiving ALT803 will be either hematologic malignancy patients (Cohort A) or Colon/Soft tissue sarcoma patients (Cohort B). Absence of dose limiting toxicity (DLT) in the DLT assessment period of 28 days must be documented for all patients enrolled a cell dose without ALT803 before the next cohort of patients to receive cytokines at that dose level can be enrolled. Patients can also be enrolled in parallel to the next cell dose level without cytokines.
Healthy volunteers accepted: No
Only the study team can determine whether someone qualifies for participation.
Inclusion criteria
Malignancies can include:
Exclusion criteria
Dose escalation of Natural Killer (NK) Cells from two infusion of starting at Dose Level 1 (1x10^7 cells/kg), dose Level-1 (1x10^6 cells/kg) if 2 of 6 patients at Level 1 develop DLTs. Escalation to dose level 2 (2.5X10^7) and Dose level 3 (5X10^7) is dependent on DLT
given at 6mcg/kg weekly for four weeks
Other names: Cytokine
Time frame: Up to 28 days
MTD Will be determined by dose limiting toxicity (DLT). The MTD will be defined as the dose level immediately below that at which 2 of 6 subjects experience a dose limiting toxicity.
Time frame: up to 28 days after beginning treatment
Measure of safety of natural killer (NK) cells in the absence of HLA matching
Time frame: Up to 12 months after beginning treatment
Complete Remission (CR): Bone marrow blasts <5%; absence of blasts with Auer rods; absence of extramedullary disease; absolute neutrophil count >1.0x10^9/L; platelet count >100x10^9/L.
CR with incomplete recovery (CRi): All CR criteria except residual neutropenia or thrombocytopenia.
Partial Remission (PR):Hematologic criteria of CR; decrease of bone marrow blast percentage to 5-25%; and decrease of pretreatment bone marrow blast percentage by ≥50%.
Cytogenetic CR (CRc): Reversion to normal karyotype at the time of morphologic CR.
Resistant disease (RD): Failure to achieve CR, CRi, or PR. Death in aplasia: Deaths occurring ≥7 days after initial treatment. Death from indeterminate cause: Deaths before completing therapy, or <7 days following completion; or deaths occurring ≥7 days after therapy with no blasts in the blood Relapse: Bone marrow blasts ≥ 5%; or reappearance of blasts in the blood; or development of extramedullary disease
Time frame: Up to 12 months after beginning treatment
Time frame: Up to 12 months after beginning treatment
Lymphoma response of Complete remission, partial remission, relapsed disease, stable disease, progressive disease and best response based on the Journal of Clinical Oncology criteria defined by Cheson in 2014
Time frame: Up to 12 months after beginning treatment
Time frame: Up to 12 months after beginning treatment
CR/CCR
Stable Disease at 90 Days (SD90)
Progressive Disease (PD)
Time frame: Up to 12 months after beginning treatment
Stringent Complete Response (sCR)
Time frame: Up to 12 months after beginning treatment
Complete hematologic response
Cytogenetic responses
Molecular response:
Time frame: Up to 12 months after beginning treatment
Complete Response: Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm (the sum may not be "0" if there are target nodes). Partial Response: At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.
Progressive Disease: At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions may be considered progression).
Stable Disease: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum of diameters while on study.
Time frame: Up to 12 months after beginning treatment
The duration of overall response is measured from the time of NK Cell infusion until the first date that recurrent or progressive disease is objectively documented (taking as reference for progressive disease the smallest measurements recorded since the treatment started).
Time frame: Up to 12 months after beginning treatment
Overall survival is measured from the date of first infusion of NK cells to the date of death from any cause; patients not known to have died at last follow up are censored on the date they were last known to be alive.
Time frame: Up to 12 months after beginning treatment
Only those patients achieving complete response (CR) or complete response with incomplete recovery (CRI). It is measured from the date of infusion of NK cells until the date of relapse or death from any cause; patients not known to have relapsed or died at last follow up are censored on the date they were last examined.
Time frame: up to 28 days after beginning treatment
Measurement of in vivo NK cell levels following cell product infusion will be done on peripheral blood by flow cytometry (CD3- CD56+ positive cells). This will be done on peripheral blood samples of patients. Measurement of successful donor NK cell persistence (absence of cell product rejection) will be defined as measurement of >100 NK cell/µL
