The purpose of this study is to explore the use of a BMT regimen that, instead of chemotherapy, uses a low dose of radiation, combined with two immunosuppressive drugs. This type BMT procedure is described as nonmyeloablative, meaning that it does not destroy the patient s bone marrow. It is hoped that this type of BMT will be safe for patients normally excluded from the procedure because of their age and other reasons.
To participate in this study, patients must be between the ages of 18 and 65 and have a sibling who is a well-matched stem-cell donor. Beyond the standard BMT protocol, study participants will undergo additional procedures. The donor will receive G-CSF by injection for five days; then his or her stem cells will be collected and frozen one month prior to BMT. Approximately one month later, the patient will be given two immune-suppressing drugs, Campath 1-H and Sirolimus, as well as a single low dose of total body irradiation and then the cells from the donor will be infused.
Prior to their participation in this study, patients will undergo the following evaluations: a physical exam, blood work, breathing tests, heart-function tests, chest and sinus x-rays, and bone-marrow sampling.
