To determine the safety and efficacy of decitabine in patients with Philadelphia chromosome-positive chronic myelogenous leukemia blastic phase that were previously treated with imatinib mesylate (STI 571) and became resistant/refractory or were found to be intolerant to the drug.
To determine the safety and efficacy of decitabine in patients with Philadelphia chromosome-positive chronic myelogenous leukemia accelerated phase that were previously treated with imatinib mesylate (STI 571) and became resistant/refractory or were found to be intolerant to the drug.
1. Determine the feasibility of generation of autologous Acute Myelogenous Leukemia (AML) or Chronic Myelogenous Leukemia in myeloid blast crisis (CML/BC) derived dendritic cell activated lymphocytes (DC/AL) in poor prognosis patients. 2. Determine the toxicity of autologous leukemia derived dendritic cell activated lymphocytes (DC/AL) in patients with AML or CML/BC. 3. Quantitate circulating immune effector cells in patients after infusion of DC/AL. 4. Record the efficacy of AML or CML/BC derived dendritic cells and activated lymphocytes in promoting and sustaining remission in patients with AML or CML/BC.
Primary Objectives: To evaluate response rates of acute or chronic Graft-versus-host disease (GVHD) following CD8 depleted DLI (Depleted Donor Lymphocyte Infusions) in patients with Chronic myelomonocytic leukemia (CMML), chronic lymphoid leukemia (CLL), Non-Hodgkin's lymphoma (NLM), Multiple Myeloma (MM) and Hodgkin's Lymphoma (HD). Secondary Objectives: - To evaluate safety and treatment related mortality after CD8 depleted DLI. - To evaluate the time to onset of GVHD following DLI and response to GVHD treatment. - To evaluate the incidence and timing of pancytopenia following DLI. - To evaluate disease-free survival, overall survival and relapse rates in three cohorts of patients; early relapse CML, late relapse CML and lymphoproliferative disorders (HD, CLL, NHL and MM). - To evaluate the need and efficacy of second or subsequent CD8 depleted donor lymphocyte infusions. - To evaluate the number of apheresis procedures needed to collect appropriate doses of CD4+ cells.
The are a variety of cancerous diseases of the blood and bone marrow that can be potentially cured by bone marrow transplantation (BMT). Diseases like leukemia, lymphoma, and multiple myeloma are among the conditions that can be treated with BMT. Some patients with these diseases can be treated with medical chemotherapy alone. However, patients who relapse following chemotherapy are usually not curable with additional chemotherapy treatments. The only option known to provide a potential cure if this occurs is BMT. Allogenic transplants are cells collected from relatives of the patient. The transplant requires additional high intensity chemotherapy and radiation in order to destroy cancerous cells. In the process, many normal bone marrow cells are also destroyed. This is the reason for transplanting stem cells. The stem cells help to build new functioning bone marrow, red cells, white cells, and platelets. In addition, the immune cells from the donor are implanted into the recipient s body and help to fight off infection and kill remaining cancerous cells. Unfortunately, the powerful doses of chemotherapy and radiation therapy associated with allogenic BMT have toxic side effects and often make BMTs too dangerous to attempt in many patients. In order to reduce the complications of BMT, and make it a safer available option for patients with cancers of the blood and bone marrow, researchers have developed a new approach to the BMT. In this study researchers plan to use stem cells collected from the blood stream of patient s relatives rather than from the bone marrow (blood progenitor/stem cell transplant). In addition, researchers plan to use low doses of chemotherapy and no radiation therapy to reduce side effects. The majority of the cancer killing effect will be the responsibility of the stem cell transplant rather than the chemotherapy.
