Active clinical trials for "Leukemia, Lymphoid"

The objectives of this study are to evaluate the safety and efficacy of OSI-461 in CLL patients.

The goal of this clinical research study is to learn if combining cord blood units to make the cells "take" faster in recipients will help to improve the results of cord blood transplants.

The purpose of this study is to find the highest safe dose and to assess the anti-tumor effect of liposomal vincristine with dexamethasone in patients with relapsed or refractory acute lymphoblastic leukemia (ALL).

This randomized phase III trial is studying dexamethasone to see how well it works compared to prednisone during induction therapy. This trial is also studying methotrexate and leucovorin calcium to see how well they work compared to methotrexate alone during maintenance therapy in treating patients with newly diagnosed acute lymphoblastic leukemia (ALL). Drugs used in chemotherapy, such as dexamethasone, prednisone, methotrexate, and leucovorin calcium, work in different ways to stop cancer cells from dividing so they stop growing or die. Giving more than one drug may kill more cancer cells. It is not yet known which combination chemotherapy regimen is more effective in treating acute lymphoblastic leukemia.

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. Combining more than one drug and giving them in different ways may kill more cancer cells. It is not yet known which regimen of combination chemotherapy is more effective for acute lymphoblastic leukemia PURPOSE: Randomized phase III trial to compare different regimens of combination chemotherapy in treating children who have newly diagnosed acute lymphoblastic leukemia.

RATIONALE: 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. Combining chemotherapy and radiation therapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: Phase I trial to study the effectiveness of high-dose combination chemotherapy followed by total-body irradiation and peripheral stem cell transplantation in treating patients with chronic lymphocytic leukemia.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of bone marrow transplantation in treating patients with chronic lymphocytic leukemia.

This study will evaluate the safety and effectiveness of stem cell transplantation in which the donors T lymphocytes have undergone "selective depletion." Certain patients with cancers of the blood undergo transplantation of donated stem cells to generate new and normally functioning bone marrow. In addition to producing the new bone marrow, the donor's T-lymphocytes also fight any tumor cells that might have remained in the body. This attack on tumor cells is called a "graft-versus-leukemia" (GVL) effect. However, another type of T-lymphocyte from the donor may cause what is called "graft-versus-host-disease" (GVHD), in which the donor cells recognize the patient's cells as foreign and mount an immune response to reject them. Selective depletion is a technique that was developed to remove the T-lymphocytes that cause harmful GVHD, while keeping those that produce the desirable GVL effect.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of gemcitabine in treating children who have relapsed or refractory acute lymphoblastic leukemia or acute myelogenous leukemia.
