Immunosuppressive Preparation Followed by Blood Cell Transplant for the Treatment of Blood Cancers in Older Adults
This study has been completed.
Sponsored by: National Heart, Lung, and Blood Institute (NHLBI)
Information provided by: National Institutes of Health Clinical Center (CC)
ClinicalTrials.gov Identifier: NCT00001637
  Purpose

Diseases such as leukemia, lymphoma, and multiple myeloma fall into the category of blood cancers. Some of these conditions can now be cured by bone marrow transplantation (BMT). The ability of BMT to cure these conditions has been credited to the use of high doses of chemotherapy, radiation therapy, and the antileukemia effect of the transplant.

Because the effectiveness of BMT relies on the use of high doses of chemotherapy and total body irradiation (TBI), it is a therapy associated with toxic side effects. These side effects are often deadly and have limited BMT for use in patients under the age of 55.

In this study researchers plan to treat older patients between the ages of 55 to 75 years with blood cell transplants taken from donors who are genetically matched relatives of the patient. In order to decrease the toxic side effects associated with the transplant, researchers will not use chemoradiotherapy. Instead they plan to use intensive immunosuppressive therapy and allow the transplanted cells to take effect....

Detailed Description:

Patients with adult leukemias, non-Hodgkin's lymphoma and multiple myeloma, can now be cured by allogeneic bone marrow transplantation (BMT). This curative effect has been ascribed to the use of high dose chemoradiotherapy and the antileukemia effect of the graft.

The assumption that BMT relies on the myeloablative effect of high dose chemotherapy and total body irradiation (TBI), has largely restricted allogeneic bone marrow transplantation in adults under the age of 55 years. Toxicity related mortality increases progressively with age and although some transplant centers carry out BMT in patients up to the age of 60 years it is generally accepted that treatment related mortality prohibits the use of allogeneic bone marrow transplantation in patients beyond the age of 55 years.

Several in vitro studies have demonstrated the existence of donor-derived CD4 and CD8 positive lymphocytes with specific reactivity for the patients leukemia and a potent graft versus leukemia (GVL) effect. This GVL effect is best seen in patients with relapse CML after bone marrow transplantation where a single infusion of donor lymphocytes can induce complete remission.

In this protocol we treat older patients between the ages of 55 to 71 years with hematologic disorders with an allogeneic stem cell transplant from an HLA identical sibling, using intensive immunosuppressive regimen without myeloablation in attempts to decrease the transplant related toxicity while preserving the antileukemia effect of the graft. The low intensity nonmyeloablative conditioning regimen will provide adequate immunosuppression to allow stem cell and lymphocyte engraftment. T-cell replete, donor-derived, granulocyte colony stimulating factor (G-CSF) mobilized peripheral blood stem cells (PBSC) will be used to establish hematopoietic and lymphoid immune reconstitution. We will add back lymphocytes in patients with less than 75% donor marrow chimerism as an attempt to prevent graft rejection.

The end points of this study are engraftment, degree of donor-host chimerism, incidence of acute and chronic GVHD, transplant related morbidity and mortality as well as survival.

INCLUSION CRITERIA - DONOR:

HLA identical family donor, up to 75 years old.

Fit to receive G-CSF and give peripheral blood stem cell (normal blood count, normotensive, no history of stroke, no history of severe heart disease).

EXCLUSION CRITERIA:
