Active clinical trials for "Leukemia, Lymphoid"

Phase II trial to study the effectiveness of 506U78 in treating patients with recurrent or refractory hematologic cancer. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase III trial to compare the effectiveness of combination chemotherapy 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. Combining more than one drug may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients who have acute B-lymphoblastic leukemia or recurrent non-Hodgkin's lymphoma.

Clofarabine (injection) is approved by the Food and Drug Administration (FDA) for the treatment of pediatric patients 1 to 21 years old with relapsed acute lymphoblastic leukemia (ALL) who have had at least 2 prior treatment regimens. The purpose of this study is to determine whether Clofarabine is safe and effective in the treatment of Acute Lymphoblastic Leukemia (ALL.)

RATIONALE: Monoclonal antibodies can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage cancer cells. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill cancer cells. PURPOSE: Phase II trial to study the effectiveness of monoclonal antibody therapy, cyclophosphamide, and total-body irradiation followed by peripheral stem cell transplantation in treating patients who have advanced recurrent acute lymphocytic leukemia.

Monoclonal antibodies can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. PURPOSE: Phase II trial to study the effectiveness of fludarabine plus high-dose cyclophosphamide and rituximab in treating patients who have previously untreated chronic lymphocytic leukemia.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients who have untreated acute lymphoblastic leukemia.

This pilot clinical trial studies low-dose total body irradiation and donor peripheral blood stem cell transplant followed by donor lymphocyte infusion in treatment patients with non-Hodgkin lymphoma, chronic lymphocytic leukemia, or multiple myeloma. Giving total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When 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. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them. Giving an infusion of the donor's white blood cells (donor lymphocyte infusion) may boost this effect.

This phase II trial studies how well fludarabine phosphate with radiation therapy and rituximab followed by donor stem cell infusions work in treating patients with high-risk chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) with low side effects. Nonmyeloablative stem cell transplants use low doses of chemotherapy (fludarabine phosphate) and radiation to suppress the patient's immune system enough to prevent rejection of the donor's stem cells. Following infusion of donor stem cells, a mixture of the patient's and the donor's stem cells will exist and is called "mixed chimerism". Donor cells will attack the patient's leukemia. This is called the "graft-versus-leukemia" effect. Rituximab will be given 3 days before and three times after infusing stem cells to help in controlling CLL early after transplant till the "graft-versus-leukemia" takes control. Further, rituximab could augment the "graft-versus-leukemia" effect by activating donor immune cells and hence improve disease control. Sometimes the transplanted cells from a donor can also attack the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.

This phase I trial is studying the side effects and best dose of tanespimycin when given with cytarabine in treating patients with relapsed or refractory acute myeloid leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, chronic myelomonocytic leukemia, or myelodysplastic syndromes. Drugs used in chemotherapy, such as tanespimycin and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Tanespimycin may also help cytarabine kill more cancer cells by making cancer cells more sensitive to the drug. Giving tanespimycin together with cytarabine may kill more cancer cells.
