Active clinical trials for "Leukemia"

This phase II trial studies the side effects and the best dose of alemtuzumab when given together with fludarabine phosphate and low-dose total body irradiation (TBI) and how well it works before donor stem cell transplant in treating patients with hematological malignancies. Giving chemotherapy and low-dose TBI before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. Also, monoclonal antibodies, such as alemtuzumab, can find cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine (CSP) and mycophenolate mofetil (MMF) after transplant may stop this from happening.

The primary objectives are a) to establish the maximum tolerated dose (MTD) of gemtuzumab ozogamicin in combination with cytarabine and daunorubicin, and b) to assess the safety of gemtuzumab ozogamicin when given concurrently with cytarabine and daunorubicin.

RATIONALE: Chemotherapy, such as fludarabine and thiotepa, and radiation therapy may destroy cancerous blood-forming cells (stem cells) in the blood and bone marrow. Giving healthy stem cells from a donor whose blood closely resembles the patient's blood will help the patient's bone marrow make new stem cells that become red blood cells, white blood cells, and platelets. PURPOSE: This phase I/II trial is studying the side effects of total-body irradiation, fludarabine, and thiotepa and to see how well they work in treating young patients who are undergoing a donor stem cell transplant for hematologic cancer.

The goal of this clinical research study is to see if low intensity chemotherapy given together with the new drug 90Y Zevalin, followed by a transplant of blood or marrow stem cells from a donor can increase the length of remission in patients with leukemia and lymphoma. The safety of this treatment will also be studied.

Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Imatinib mesylate may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth. Combining more than one chemotherapy drug with imatinib mesylate may kill more cancer cells. Randomized phase II trial to study the effectiveness of combination chemotherapy and imatinib mesylate in treating children who have relapsed acute lymphoblastic leukemia.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Colony-stimulating factors such as filgrastim and sargramostim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. It is not yet known whether combination chemotherapy is more effective followed by filgrastim or sargramostim in treating leukemia. PURPOSE: Randomized phase II trial to compare the effectiveness of combination chemotherapy followed by filgrastim with that of combination chemotherapy followed by sargramostim in treating patients who have relapsed or refractory acute myeloid leukemia or acute lymphoblastic leukemia.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. It is not yet known if combining combination chemotherapy with monoclonal antibody therapy will kill more cancer cells. PURPOSE: Randomized phase III trial to determine the effectiveness of combination chemotherapy with or without gemtuzumab ozogamicin in treating patients who have acute myeloid leukemia.

Patients will have immune cells collected and then expanded outside of the body. Patients will receive an infusion of a large number of expanded immune cells. There will be three dose levels studied. The goal of the study will be to determine the safety as well as potential efficacy of this treatment.

Participants in this study have a hematologic malignancy which is a disorder in the bone marrow that affects the body's ability to create blood. Participants might benefit from receiving an allogeneic stem cell transplant (meaning the cells come from a donor). The participants donor is a family member. Stem cells are cells in the bone marrow and blood that can form a whole new blood system.

RATIONALE: Biological therapies, such as cellular adoptive immunotherapy, stimulate the immune system in different ways and stop cancer cells from growing. PURPOSE: This phase I trial is studying the side effects of cellular adoptive immunotherapy in treating patients with acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndromes that relapsed after donor stem cell transplant.
