- Brief Summary
RATIONALE: Giving high doses of chemotherapy before a donor stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. Colony stimulating factors, such as aldesleukin and GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of chemotherapy. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells that have been treated with antibodies after the transplant may help increase this effect. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus and mycophenolate mofetil after transplant may stop this from happening.
PURPOSE: This phase I trial is studying the side effects and best dose of donor T cells given together with low-dose aldesleukin and low-dose GM-CSF after donor stem cell transplant in treating patients with relapsed or refractory non-Hodgkin's lymphoma.
- Detailed Description
OBJECTIVES:
* Determine the maximum tolerated dose of donor-derived allogeneic anti-CD3 X anti-CD20 bispecific antibody (CD20Bi)-armed activated T cells (ATC) when given with low-dose aldesleukin and low-dose sargramostim (GM-CSF) after allogeneic stem cell transplantation in patients with relapsed or refractory CD20-positive non-Hodgkin lymphoma.
* Perform trafficking studies using indium I 111-labeled unarmed ATC and ATC armed with CD20Bi in patients with evaluable lymphoma sites to determine whether armed ATC specifically traffic to tumor sites and correlate these data with CT and PET scans.
* Evaluate immune responses and immune reconstitution of T and B cells.
OUTLINE: All patients receive high-dose chemotherapy that is standard of care for their disease. Peripheral blood lymphocytes are obtained from the HLA-identical sibling donor and cultured to obtain activated T cells (ATC), some of which are subsequently armed with CD20 bispecific antibody (CD20Bi) and cryopreserved for later use. Patients then undergo allogeneic hematopoietic stem cell transplantation (SCT).
Patients receive ATC-CD20Bi IV on days 40, 70, 100, 130, and 160 after SCT. Patients receive low-dose aldesleukin subcutaneously (SC) once daily for 7 days beginning within 24 hours after each ATC-CD20Bi infusion and low-dose sargramostim (GM-CSF) SC every other day for 3 doses beginning within 24 hours after each infusion of ATC-CD20Bi. Patients also receive tacrolimus and mycophenolate mofetil as standard graft-vs-host disease prophylaxis. Treatment continues in the absence of unacceptable toxicity.
Some patients with well-defined or evaluable masses receive indium I 111 (\^111I)-labeled ATC-CD20Bi IV and \^111I-labeled unarmed ATC and then undergo whole-body imaging for trafficking studies.
After completion of study treatment, patients are followed at 6 months, 12 months, and then annually thereafter.
