Peripheral Blood Mobilized Hematopoietic Precursor Cell Transplantation Followed by T Cell Add-Back for Hematological Malignancies - Effect of Peri-transplant Cyclosporine on Chimerism
This study will evaluate the safety and effectiveness of stem cell transplantation in which
the donor's T cells (a type of lymphocyte, or white blood cell) are removed and then added
back. Certain patients with bone marrow malignancies undergo transplantation of donated stem
cells to generate new and normally functioning bone marrow. However, T-cells from the donor
may see the patient's cells as foreign and mount an immune response to reject them, causing
what is called "graft-versus-host-disease" (GVHD). Therefore, in this protocol, T-cells are
removed from the donor cells to prevent this complication. However, because T-cells are
important in fighting viral infections as well as any remaining malignant cells (called
graft-versus-leukemia effect), the donor T-cells are given to the patient (added back) at a
later time after the transplant when they can provide needed immunity with less risk of
causing GVHD.
Patients between 10 and 55 years of age with acute or chronic leukemia, myelodysplastic
syndrome, or myeloproliferative syndrome may be eligible for this study. Prospective
participants and their donors are screened with a medical history and physical examination,
blood tests (including a test to match for genetic compatibility), breathing tests, chest
and sinus x-rays, and tests of heart function. They also undergo a bone marrow biopsy and
aspiration. For this procedure, done under local anesthetic, about a tablespoon of bone
marrow is withdrawn through a needle inserted into the hipbone.
They undergo apheresis to collect lymphocytes for research studies. This procedure involves
collecting blood through a needle in the arm, similar to donating a unit of blood. The
lymphocytes are then separated and removed by a cell separator machine, and the rest of the
blood is returned through a needle in the other arm.
Before treatment begins, patients have a central intravenous line (flexible plastic tube)
placed in a vein in the chest. This line remains in place during the stem cell transplant
and recovery period for drawing and transfusing blood, giving medications, and infusing the
donated cells. Preparation for the transfusion includes high-dose radiation and
chemotherapy. Patients undergo total body irradiation in 8 doses given in two 30-minute
sessions a day for 4 days. Eight days before the transplant, they begin taking fludarabine,
and 3 days before the procedure they start cyclophosphamide.

Bone marrow stem cell transplant studies carried out by the National Heart Lung & Blood
Institute (NHLBI) Bone Marrow Transplantation (BMT) Unit have focused on approaches to
optimize the stem cell and lymphocyte dose in order to improve transplant survival and
increase the graft-versus-leukemia effect. The aim is to create the transplant conditions
that permit rapid donor immune recovery without causing graft-versus-host disease (GVHD) by
using reduced post-transplant immunosuppression in conjunction with a transplant depleted of
T cells to a fixed low dose, below the threshold known to be associated with GVHD.
We have found that the outcome from transplant is improved by controlling the stem cell
(CD34+ cell) and T lymphocyte (CD3+ cell) dose. We use the "Nexell Isolex 300i" system to
obtain high CD34+ doses depleted of lymphocytes to a fixed CD3+ T cell dose of 2 x 104/kg.
The use of the cell separator and the monoclonal antibodies is covered by an Investigational
Device Exemption. A persisting problem with these T cell depleted transplants has been the
slow acquisition of full donor T cell engraftment (T cell chimerism). Two previous protocols
have failed to increase the speed of donor T cell chimerism. Patients with mixed
donor-recipient T cell populations are known to be at higher risk for late graft rejection
and leukemic relapse after transplant. Therefore, the achievement of full donor chimerism
remains an important therapeutic goal. In this study we will test whether cyclosporine given
between day -6 and +21 after transplant can significantly improve day 30 T cell chimerism
(the principle end-point). The study also will measure the incidence of acute and chronic
GVHD, day 100 transplant related mortality, cytomegalovirus reactivation, relapse, and
disease-free survival with appropriate safety stopping rules.
This protocol follows closely previous studies in this series. Three additional
modifications will be made however: 1) The first T cell add-back will be delayed until day
60 (instead of day 45) so as to continue to allow a 45 day period without cyclosporine
immunosuppression. 2) No day 100 T cell add-back will be given. (In previous studies many
patients have, for protocol-defined reasons, not received the second transfusion and there
is no evidence that it is required). 3) Patients with high-risk leukemias with a high
relapse probability will receive an additional chemotherapy agent prior to transplant using
etoposide (VP16) 60mg/kg to improve the chance of remaining in remission.
