Donor Peripheral Stem Cell Transplant in Treating Patients With Relapsed Acute Myeloid Leukemia
Allogeneic Natural Killer Cells in Patients With Relapsed Acute Myelogenous Leukemia
RATIONALE: Giving chemotherapy before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells and natural killer (NK) cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets.
PURPOSE: This clinical trial is studying how well a peripheral stem cell transplant using NK cells from a donor works in treating patients with relapsed acute myeloid leukemia.

Descrizione dettagliata
OBJECTIVES:
Primary
- Evaluate the in vivo expansion of natural killer (NK) cells 14 days after treatment with allogeneic NK cell-enriched peripheral blood stem cell transplantation in patients with relapsed acute myeloid leukemia.
Secondary
- Determine the response rate, in terms of complete remission, in patients treated with this regimen.
- Correlate complete remission rate with NK cell expansion, interleukin-15 levels, and donor/recipient killer immunoglobulin receptor (KIR) ligand matching status in patients treated with this regimen.
- Determine the overall and progression-free survival of patients treated with this regimen.
- Determine the toxicity of this regimen in these patients.
OUTLINE: This is an open-label study.
- Induction therapy: Patients receive fludarabine IV on days -6 to -2 and cyclophosphamide IV on day -5 or on days -5 and -4.
- Allogeneic natural killer (NK) cell-enriched peripheral blood stem cell transplantation: Patients receive allogeneic NK cell-enriched peripheral blood stem cells IV over 15-60 minutes on day 0. Patients also receive interleukin-2 subcutaneously beginning on day 0 and continuing 3 times a week for up to 2 weeks.
After completion of study treatment, patients are followed periodically for 3 months.

---|---|---|
Number of Patients With Natural Killer (NK) Cell Expansion

Misura Descrizione |
Lasso di tempo |
---|---|---|
Number of Patients With Complete Remission
Lasso di tempo: Day 28-35
|
Clinical response is determined by achievement of a complete remission (CR) as judged by morphological criteria (< 1% blasts in bone marrow with neutrophil recovery).
|
Day 28-35
|
Median Time to Disease Relapse (Months)
Lasso di tempo: From 1st Day of treatment until death or receipt of bone marrow transplant.
|
Follow-up continued every 3 months after the allogeneic natural killer (NK) cell infusion, unless they were transplanted, relapsed or had progressive disease.
Time in months to relapse of disease is calculcated from 1st day of treatment with NK cells.
Relapse occurs when leukemia is detected in bone marrow or blood.
|
From 1st Day of treatment until death or receipt of bone marrow transplant.
|
Overall Survival Time of Patients With Complete Remission
Lasso di tempo: From Day 1 of Treatment until death or patient received bone marrow transplant.
|
Median number of months patients were alive after NK cell infusion.
|
From Day 1 of Treatment until death or patient received bone marrow transplant.
|
Number of Patients With Complete Remission and Natural Killer Cell Expansion
Lasso di tempo: Day 14
|
Includes patients who had both a complete remission of disease and an expansion of natural killer cells.
|
Day 14
