Active clinical trials for "Leukemia, Lymphoid"

RATIONALE: Studying the physical and emotional needs of parents who are caring for children receiving chemotherapy for cancer may help doctors plan effective treatments for the patient that allow for improved quality of life of the patient's family. PURPOSE: This clinical trial is studying the different physical and emotional needs of parents whose children are undergoing chemotherapy for acute lymphoblastic leukemia either in an outpatient clinic or in the hospital.

This phase I/II trial is studying the side effects of biological therapy and to see how well it works in treating patients with advanced myelodysplastic syndrome, chronic myeloid leukemia, acute myeloid leukemia, or acute lymphoblastic leukemia. Biological therapies, including immunotherapy, can potentially be used to stimulate the immune system and stop cancer cells from growing. Immunotherapy given to patients who have undergone donor stem cell transplantation may be a way to eradicate remaining cancer cells

This phase I trial is studying the side effects and best dose of tipifarnib and bortezomib in treating patients with acute leukemia or chronic myelogenous leukemia in blast phase. Tipifarnib and bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving tipifarnib together with bortezomib may kill more cancer cells.

RATIONALE: Drugs used in chemotherapy, such as fludarabine, cyclophosphamide, and mitoxantrone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving combination chemotherapy together with rituximab may kill more cancer cells. It is not yet known whether giving combination chemotherapy together with rituximab is more effective than combination chemotherapy alone in treating chronic lymphocytic leukemia. PURPOSE: This randomized phase II trial is studying how well giving combination chemotherapy with or without rituximab works in treating patients with previously treated chronic lymphocytic leukemia.

This randomized phase II trial studies how well giving tacrolimus and mycophenolate mofetil (MMF) with or without sirolimus works in preventing acute graft-versus-host disease (GVHD) in patients undergoing donor stem cell transplant for hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, and total-body-irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving MMF and tacrolimus with or without sirolimus after transplant may stop this from happening.

The purpose of this trial is to assess the efficacy, safety, tolerability, biologic activity, and pharmacokinetics of AMN107 in six groups of patients with one of the following conditions: Relapsed/refractory Ph+ Acute lymphoblastic leukemia (ALL) (arm 1) Group A - Imatinib failure only (arms 2, 3 and 4) imatinib-resistant or intolerant CML - Chronic Phase (CP) imatinib-resistant or intolerant CML - Accelerated Phase (AP) imatinib-resistant or intolerant CML - Blast Crisis (BC) Group B - Imatinib and other TKI failure (arms 2, 3 and 4) imatinib-resistant or intolerant CML - Chronic Phase (CP) imatinib-resistant or intolerant CML - Accelerated Phase (AP) imatinib-resistant or intolerant CML - Blast Crisis (BC) Hypereosinophilic syndrome/chronic eosinophilic leukemia (HES/CEL) (arm 5) Systemic mastocytosis (Sm) (arm 6)

RATIONALE: Biological therapies, such as denileukin diftitox, may interfere with the growth of cancer cells and slow the growth of chronic lymphocytic leukemia. PURPOSE: This phase II trial is studying how well denileukin diftitox works in treating patients with fludarabine-refractory B-cell chronic lymphocytic leukemia.

This purpose of this study is to assess the toxicity and the rate of complete and overall response using fludarabine, rituximab, and alemtuzumab to treat patients with B-chronic lymphocytic leukemia or small lymphocytic leukemia who have received previous treatment.

This phase II trial is studying how well giving fludarabine together with rituximab followed by alemtuzumab works in treating patients with chronic lymphocytic leukemia. Monoclonal antibodies, such as rituximab and alemtuzumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others can find cancer cells and help kill them or carry cancer-killing substances to them. Drugs used in chemotherapy, such as fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving fludarabine together with rituximab followed by alemtuzumab may kill more cancer cells.

This phase I/II trial studies the side effects and best dose of alemtuzumab when given together with combination chemotherapy and to see how well it works in treating patients with untreated acute lymphoblastic leukemia. Monoclonal antibodies, such as alemtuzumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Drugs used in chemotherapy also work in different ways to kill cancer cells or stop them from growing. Giving alemtuzumab together with combination chemotherapy may be a better way to block cancer growth.
