About this trial
This is an interventional treatment trial for Acute Myeloid Leukemia focused on measuring Natural Killer Cell, ALT-803
Eligibility Criteria
Inclusion Criteria:
- Patients must have histologic confirmation of relapsed and or refractory hematologic malignancy, locally advanced or metastatic colon/rectal carcinoma, or refractory and/or relapsed soft tissue sarcomas and have failed at least one standard line of therapy.
- Patients will be eligible if they have either declined standard treatment regimens or if there is no standard approach to curative salvage therapy per National Comprehensive Cancer Network (NCCN) guidelines in the setting of relapsed/refractory disease.
- In addition, patients for whom a potential 29-day delay in treatment will not interfere with the subject's potential therapeutic options can be eligible per the treating physician's discretion.
Malignancies can include:
- Acute myeloid leukemia
- Myelodysplastic syndrome
- Acute lymphoblastic leukemia
- Chronic myeloid leukemia
- Chronic lymphocytic leukemia
- Non Hodgkin Lymphoma
- Hodgkin Lymphoma
- Myeloproliferative syndromes
- Plasma cell myeloma
- Colon/rectal carcinoma
Soft tissue sarcomas including but not limited to Ewing's sarcoma and Rhabdomyosarcoma
- Patients must have recovered from acute toxicities of prior chemotherapy or stem cell transplant. Any prior non-hematologic vital organ toxicity (cardiac, pulmonary, hepatic, renal) of previous therapy must have resolved to grade 1 or less.
- All previous chemotherapy or radiation must be completed at least 3 weeks prior to study entry. Immunologic therapy must be completed at least 3 weeks prior to study entry. Patients with prior stem cell transplant must be greater than 365 days post-transplant.
- Eastern Cooperative Oncology Group (ECOG) performance status ≤2
Organ function criteria (There is no exclusion for the presence of cytopenias),
- Serum total bilirubin <2 mg/dl (except if known Gilbert syndrome and normal transaminases)
- Aspartate aminotransferase (AST) (SGOT) < 2.5 X institutional upper limit of normal
- Alanine aminotransferase (ALT) (SGPT) < 2.5 X institutional upper limit of normal

Women of child-bearing age must have documented negative pregnancy test prior to start of lympho-depleting regimen.
Exclusion Criteria:
- Subjects receiving any other investigational agents.
- Subjects for whom a potential 29-day delay in treatment will interfere with the subject's potential therapeutic options.
- Patients with untreated malignant involvement of the central nervous system (CNS) should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.

Average duration of relapse free survival
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.

5. Study Description
Brief Summary
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).
Detailed Description
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:
Describe safety profile / toxicity of combining ALT-803 with NK cell adoptive therapy.
Determine antitumor activity of allogeneic NK cells with ALT-803 support.
Determine if a lymphocyte depleting regimen is adequate for preventing early elimination of HLA-mismatched donor NK cells by host T-cells.
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.
