Brief Summary

This is a phase II, single-center study to evaluate the efficacy of a novel cytoreductive regimen followed by CD34+E- selected T cell depleted allogeneic stem cell (or soybean agglutinated and E-rosetted BM) transplant as treatment for patients with acute and chronic leukemias, lymphoma and myelodysplstic syndrome/PNH. The impact of the change in conditioning regimen and use of CD34-selected T cell depleted PBSCs on transplanted related morbidity and mortality and disease free survival will be assessed.

Detailed Description

The purpose of this study is: (1) to try to kill any cancer or precancer cells that are in your body, and to reduce the side effects of a transplant, which we have seen in our previous studies, (2) to see if this treatment with a new recipe of radiation and chemotherapy can suppress your immune system enough for the stem cells to 'take' and grow, (3) to see if the specially prepared stem cells can grow in you without a problem called graft-versus-host disease (GvHD) occurring.

One of the major side effects of any stem cell transplant is a condition known as graft vs. host disease or GVHD. GVHD is an immune reaction caused by certain cells from the transplanted stem cells called T-lymphocytes (or T-cells). The T-cells from your donor may see your organs as foreign and attack them. New ways to remove the T-cells from the stem cells before the transplant are being used to try and prevent GVHD. In some studies, the removal of T-cells from the stem cells has been successful for many patients in preventing both short-term (acute) and long-term (chronic) forms of GVHD. However, the removal of T-cells may increase the chance that the new bone marrow developing from the stem cells will be rejected or will not function well. Rejection of the transplant means that some of your own cells have survived the chemo and radiation therapy, and are attacking the new bone marrow cells. This condition can be lifethreatening because of an increased risk of infections and bleeding and would require your getting more treatment and additional stem cells. Studies like this one are designed to find better ways to avoid GVHD without increasing the risk of other problems such as graft rejection.

Study Groups

Transplant Patients

Group Type: EXPERIMENTAL

cytoreductive regimen followed by a CD34+E- selected allogeneic stem cell transplant

Intervention Type: DRUG

Myeloablative and will consist of hyperfractionated TBI - 1375 cGy administered in 11 doses of 125 cGy each over a total of four days, with three doses on three days and two doses on the last day, fludarabine 25 mg/m2 IV x 5 days, and thiotepa 5mg/kg IV x 2 days. Recipients of HLA identical related transplants will not receive ATG to promote engraftment. Recipients of HLA mismatched related or unrelated stem cells will receive ATG for two days prior to the transplant. G-CSF mobilized CD34+E- PBSCs obtained from the HLA compatible donor will be infused on day 0. Post transplantation G-CSF will be administered only if clinically indicated and should begin on or after d+7.

Patients will be clinically evaluated at each clinic visit for incidence and severity of acute and chronic GVHD and transplant associated morbidity. Sequential evaluation of functional reconstitution of hematopoiesis and immunity will be made as per the BMT Service guidelines.
