Brief Summary

This phase 2 trial studies how well cluster of differentiation 8 (CD8)+ memory T-cells work as a consolidative therapy following a donor non-myeloablative hematopoietic cell transplant in treating patients with leukemia or lymphoma. Giving total lymphoid irradiation and anti-thymocyte globulin before a donor hematopoietic cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When the healthy stem 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft-versus-host disease). Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them. Giving an infusion of the donor's white blood cells, such as CD8+ memory T-cells, may boost this effect and may be an effective treatment to kill any cancer cells that may be left in the body (consolidative therapy).

Detailed Description

Participants undergo total lymphoid irradiation (TLI) on Days -11 to -7 and Days -4 to -1 and receive anti-thymocyte globulin (ATG) per standard institutional practice on Days -11 to -7. Patients also receive oral cyclosporine daily starting on Day -3, and will continue for at least 6 months post-transplant. Patients undergo standard non-myeloablative allogeneic HSCT on Day 0. Patients also receive oral mycophenolate mofetil daily beginning on Day 0 and continuing until Day 28. Participants receive an intravenous infusion of allogeneic cluster of differentiation 8 (CD8)+ memory T-cells over 10 to 20 minutes sometime between day 30 and day 60.

PRIMARY OBJECTIVES:

I. To determine the rate of conversion to full-donor chimerism (FDC) following a post-transplant infusion (Day 30-60) of freshly-enriched allogeneic CD8+ memory T-cells in patients with acute myeloid leukemia (AML), non-Hodgkin lymphoma (NHL), chronic lymphocytic leukemia (CLL), or Hodgkin lymphoma (HL), who received standard non-myeloablative total lymphoid irradiation (TLI) anti-thymocyte globulin (ATG) transplant conditioning.

SECONDARY OBJECTIVES:

I. To determine the risk of disease progression, overall and event free survival, and non-relapse mortality.

II. To determine the incidence of acute and chronic graft-versus-host disease (GVHD) following the infusion of allogeneic CD8+ memory T-cells.

OUTLINE:

Patients undergo TLI on days -11 to -7 and -4 to -1 and receive ATG per standard institutional practice on days -11 to -7. Patients also receive cyclosporine orally (PO) daily starting on day -3 and will continue for at least 6 months post-transplant. Patients undergo non-myeloablative allogeneic hematopoietic stem cell transplant (HSCT) on day 0. Patients also receive mycophenolate mofetil PO daily beginning on day 0 and continue until day 28. Based on the patient's status after the initial transplant, patients receive CD8+ memory T-cells intravenously (IV) over 10-20 minutes sometime between day 30 and day 60.

After completion of study treatment, patients are followed up periodically.

Eligibility Criteria

Inclusion Criteria

• Must have a human leukocyte antigen (HLA)-matched or single allele-mismatched adult sibling serving as donor
• Must have a myeloid or lymphoid malignant disease that is treated with TLI and ATG reduced intensity conditioning for allogeneic transplant (any of the following AML, myelodysplastic syndrome [MDS], myeloproliferative disease [MPD], CLL, B or T-cell NHL, HL)
• Patients who due to age, pre-existing medical conditions, or, prior therapy are considered to be at high risk for regimen related toxicity associated with fully ablative transplant conditioning, and therefore reduced intensity conditioning is recommended
