Background: Patients with cancers of the blood and immune system often benefit from transplants of stem cells from a genetically well-matched sibling. However, severe problems may follow these transplants because of the high-dose chemotherapy and radiation that accompany the procedure. Also, donated immune cells sometimes attack healthy tissues in a reaction called graft-versus-host disease (GVHD), damaging organs such as the liver, intestines and skin. To reduce toxicity of high-dose preparative chemotherapy, this study performs allogeneic transplant after low doses of chemotherapy. In an attempt to improve anti-tumor effects without increasing GVHD, this study uses donor immune cells (T helper 2 (Th2) cells) grown in the laboratory; some patients will receive standard donor immune cells (not grown in laboratory). All patients will receive immune modulating drugs sirolimus and cyclosporine to prevent GVHD. Objective: To determine the safety, treatment effects and rate of GVHD in patients receiving transplants that use low-intensity chemotherapy, sirolimus plus cyclosporine, and transplant booster with either Th2 cells or standard immune cells. Eligibility: Patients 16 to 75 years of age with acute or chronic leukemia, non-Hodgkin's lymphoma, Hodgkin's disease, multiple myeloma, or myelodysplastic syndrome. Patients must have a suitable genetically matched sibling donor and adequate kidney, heart and lung function. Design: The protocol has three treatment groups: cohort 1, Th2 booster at two weeks post-transplant; cohort 2, standard T cell booster at two weeks post-transplant; cohort 3, multiple infusion of Th2 cells. Condition: Hematologic Neoplasms, Myeloproliferative Disorders Intervention: Biological; therapeutic allogeneic lymphocytes Drug: Sirolimus Study Type: Interventional Study Design: Primary Purpose: Treatment Phase: Phase II
