Study Summary

Patients have a type of blood cell disorder that is very hard to cure. We are now suggesting a treatment that might help patients live longer without disease than other treatment plans would. This treatment is known as a stem cell transplant. We believe this may help patients as it allows us to give much stronger doses of drugs and radiation to kill the diseased cells than we could give without the transplant. We also think that the healthy cells may help fight any diseased cells left after the transplant. Stem Cells are special "mother" cells that are found in the bone marrow (the spongy tissue inside bones), although some are also found in the bloodstream (peripheral blood). As they grow, they become either white blood cells which fight infection, red blood cells which carry oxygen and remove waste products from the organs and tissues or platelets, which enable the blood to clot. For the transplant to take place, we will collect these stem cells from a "donor" (a person who agrees to donate these cells) and give them to recipient. Patients do not have a sibling that is a perfect match, so the stem cells will come from a donor who is the best match available. This person may be a close relative or an unrelated person whose stem cells best "matches" the patients, and who agrees to donate stem cells. Before the transplant, two very strong drugs plus total body irradiation will be given to the patient (pre-conditioning). This treatment will kill most of the blood-forming cells in the bone marrow. We will then give the patient the healthy stem cells. Once these healthy stem cells are in the bloodstream they will move to the bone marrow (graft) and begin producing blood cells that will eventually mature into healthy red blood cells, white blood cells and platelets. This research study will also use CAMPATH-1H as a pre-treatment. CAMPATH-1H is an antibody against certain types of blood cells. CAMPATH-1H is important because it stays active in the body for a long time a
