Filter by:This study will evaluate the safety and effectiveness of a combination of two antibodies, apolizumab and rituximab (Rituxan ), in treating B-cell lymphomas and chronic lymphocytic leukemia. Rituximab attaches to a molecule called CD20 on B-cell lymphomas and can cause significant shrinkage of these tumors in up to half of patients. However, it does not cure the lymphoma, which usually returns. Also, it is not as effective against leukemia. Apolizumab attaches to a protein called 1D10 on B-cell cancers and has also been able to shrink tumors in some patients. There is little experience apolizumab in patients with leukemia. This study will test whether the two antibodies together are more effective against these tumors than either one alone. Patients 18 years and older with B-cell lymphoma or chronic lymphocytic leukemia may be eligible for this study. Patients' leukemia or lymphoma cells must have both the CD20 and 1D10 antigen receptors and must have had at least one systemic treatment for their disease. Candidates are screened with a medical history and physical examination, blood and urine tests, electrocardiogram, x-rays and other imaging studies, and possibly a bone marrow aspirate (withdrawal of a small marrow sample through a needle inserted into the hip bone) and lumbar puncture (withdrawal of a small sample of cerebrospinal fluid-fluid that bathes the brain and spinal cord-through a needle placed between the bones in the lower back). Participants receive infusions of rituximab and apolizumab once a week for 4 weeks. The first patients in the study receive lower doses of apolizumab with standard doses of rituximab. If the apolizumab is well tolerated, subsequent patients are given higher doses. Patients are also given dexamethasone or another similar steroid, diphenhydramine (Benadryl ), and acetominophen (Tylenol ) to reduce reactions to the antibodies. After 4 weeks of treatment, patients are followed frequently to examine the response to treatment and evaluate drug side effects. Patients whose tumors do not grow during the 4 weeks of therapy may be offered another course of treatment at a later time. Participants are followed periodically after treatment ends until their disease worsens or the study ends. ...
The prognosis for children and adults with acute lymphoblastic leukemia (ALL) has improved significantly over the years. Nevertheless, patients who experience disease relapse or induction failure along with patients having unfavorable genetics [t(4;11) or t(9;22)] have dismal prognosis. For these patients, novel therapeutic approaches such as immunotherapy are needed. In this clinical trial, investigators evaluate whether it is feasible to make a vaccine from leukemia cells and whether this vaccine enables direct immunity against cancer cells in patients.
RATIONALE: Antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. PURPOSE: Phase I trial to study the effectiveness of antibody therapy in treating patients who have refractory or relapsed non-Hodgkin's lymphoma or chronic lymphocytic leukemia.
This randomized phase II trial is studying thalidomide and fludarabine to see how well they work compared to thalidomide alone in treating patients with hematologic cancer that has not responded to previous treatment with fludarabine. Thalidomide may stop the growth of hematologic cancer by stopping blood flow to the cancer. Combining thalidomide with fludarabine may increase the effectiveness of chemotherapy by making cancer cells more sensitive to the drug. It is not yet known whether thalidomide is more effective with or without fludarabine for hematologic cancer.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of arsenic trioxide in treating patients who have recurrent or refractory acute lymphoblastic leukemia or chronic myelogenous leukemia.
Phase II trial to study the effectiveness of arsenic trioxide in treating patients who have relapsed or refractory lymphoma or leukemia. 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. Combining chemotherapy with bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. Radiation therapy uses high-energy x-rays to damage cancer cells. Combining chemotherapy, radiation therapy, and bone marrow transplantation may kill more cancer cells. PURPOSE: Randomized phase III trial to compare high-dose chemotherapy with or without total-body irradiation before bone marrow transplantation in treating children with acute lymphoblastic leukemia.
