Active clinical trials for "Leukemia, Lymphoid"

The purpose of this study is to determine the safety and tolerability of an oral Farnesyl Protein Transferase Inhibitor (SCH 66336) as a single agent in patients with Advanced Myelodysplastic Syndrome, Acute Myelogenous Leukemia, Chronic Myelogenous Leukemia in Blast Crisis, or Acute Lymphoblastic Leukemia.

The goal of this clinical research study is to learn if giving CAMPATH-1H with rituximab can shrink or slow the growth of the disease in patients with chronic lymphoid disorders that have either not responded or whose disease has returned after treatment with standard therapies.

Phase II trial to study the effectiveness of radiation therapy following chemotherapy in treating children with CNS relapse from acute lymphoblastic leukemia. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with radiation therapy may kill more cancer cells.

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.

Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Phase I trial to study the effectiveness of BMS-214662 in treating patients who have acute leukemia, myelodysplastic syndrome, or chronic myeloid leukemia in blast phase

Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Interleukin-2 may stimulate a person's white blood cells to kill cancer cells. Combining rituximab with interleukin-2 may kill more cancer cells. Phase I trial to study the effectiveness of rituximab plus interleukin-2 in treating patients who have hematologic cancer.

RATIONALE: Drugs used in chemotherapy work in different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one chemotherapy drug may kill more cancer cells. It is not yet known which combination chemotherapy regimen is more effective for acute lymphoblastic leukemia. PURPOSE: Phase III trial to determine the effectiveness of combination chemotherapy in treating children who have newly diagnosed acute lymphoblastic leukemia.

This study will evaluate the effectiveness of an experimental drug called LMB-2 for treating chronic lymphocytic leukemia (CLL) in patients who have a protein called cluster of differentiation 25 (CD25) on their cancer cells. LMB-2 is a recombinant immunotoxin. It is made up of two parts: a genetically engineered monoclonal antibody that binds to cancer cells with CD25 on their surface, and a toxin produced by bacteria that kills the cancer cells to which it binds. LMB-2 has killed CD 25-containing cells in laboratory experiments and has caused tumors in mice to shrink. Preliminary studies in humans have shown some effectiveness in shrinking tumors in patients with various types of lymph and blood cancers. Patients 18 years of age and older with CLL who have CD25 receptor proteins on their cancer cells and whose disease has progressed within 2 years of treatment with fludarabine may be eligible for this study. Candidates are screened with a medical history and physical examination, blood and urine tests, electrocardiogram (EKG), echocardiogram, chest x-ray, computed tomography (CT) scans of the chest, abdomen and pelvis, and a bone marrow biopsy. Participants receive up to six cycles of LMB-2 therapy. Each 28-day cycle consists of 30-minute infusions of LMB-2 on cycle days 1, 3, and 5. The drug is infused through an intravenous (IV) catheter (plastic tube placed in a vein) or a central venous line-an IV tube placed in a large vein in the neck or chest that leads to the heart. Patients are admitted to the National Institutes of Health (NIH) Clinical Center for the first treatment cycle. If the infusion is well tolerated, subsequent cycles may be given on an outpatient basis. In addition to drug therapy, patients undergo the following procedures: Blood draws: Blood is drawn before, during, and after each LMB-2 infusion to measure blood levels of the drug, evaluate its effects on the cancer cells, and monitor side effects. Blood tests are also done before and during each cycle to determine how the immune system is interacting with the drug. Disease evaluations: Patients undergo a physical examination, blood tests, chest x-ray, and EKG before each treatment cycle and at follow-up visits. With the patient's permission, CT scans, echocardiogram, and bone marrow biopsies may be repeated before some treatment cycles if these tests prove useful in evaluating the disease response to LMB-2. Patients may receive up to six cycles of LMB-2 as long as their cancer does not worsen and they do not develop serious side effects. At the end of the treatment cycles, patients will have blood tests done weekly by their local physician, and the results will be sent to the NCI study investigators.

RATIONALE: Drugs used in chemotherapy, such as arsenic trioxide, work in 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 their growth. Combining arsenic trioxide with imatinib mesylate may kill more cancer cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of arsenic trioxide when given with imatinib mesylate and to see how well they work in treating patients with accelerated phase or blastic phase chronic myelogenous leukemia or Philadelphia chromosome-positive acute lymphoblastic leukemia.

RATIONALE: Drugs used in chemotherapy, such as bryostatin 1, work in different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Bryostatin 1 may help rituximab kill more cancer cells by making them more sensitive to the drug. PURPOSE: This phase II trial is studying how well giving bryostatin 1 together with rituximab works in treating patients with B-cell non-Hodgkin's lymphoma or chronic lymphocytic leukemia that has not responded to previous treatment with rituximab.
