Filter by:RATIONALE: Giving chemotherapy and colony-stimulating factors, such as G-CSF, may increase the number of stem cells in the blood. The stem cells are collected from the patient's blood and stored. Chemotherapy or radiation therapy is given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy and radiation therapy. PURPOSE: This clinical trial is studying how well an autologous stem cell transplant works in treating patients with acute myeloid leukemia.
Allogeneic hematopoietic transplant is curative for many patients with hematological neoplasms but conditions to provide optimal engraftment and anti-tumor efficacy with minimal toxicity are still under way. Clofarabine is a newly licensed agent with dramatic anti-leukemic activity. Its incorporation into a regimen for pre-transplant conditioning of acute leukemia and lymphoma patients is logical, exploiting both the anti-tumor activities it is recognized to have and the immunosuppressive activity seen with drugs in its class.
RATIONALE: Aldesleukin may stimulate natural killer cells to kill cancer cells. Treating natural killer cells with aldesleukin in the laboratory may help the natural killer cells kill more cancer cells when they are put back in the body. Giving monoclonal antibodies, such as rituximab, and chemotherapy drugs, such as fludarabine and cyclophosphamide, before a donor natural killer cell infusion helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. PURPOSE: This phase I/II trial is studying how well giving rituximab and chemotherapy followed by a donor natural killer cell infusion that has been treated in the laboratory with aldesleukin followed by aldesleukin works in treating patients with non-Hodgkin lymphoma or chronic lymphocytic leukemia.
RATIONALE: Monoclonal antibodies can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Radioactive monoclonal antibodies, such as yttrium Y 90 monoclonal antibody, can find cancer cells and either kill them or carry cancer-killing substances to them without harming normal cells. PURPOSE: This phase I trial is studying the side effects and best dose of a yttrium Y 90 monoclonal antibody and how much radiation is taken in by the organs in the body in treating patients with advanced leukemia or other hematologic disorder.
The purpose of this study is to evaluate the activity of bexarotene, a retinoic acid class drug, in patients with Acute Myeloid Leukemia (AML) that has returned after or is resistant to standard chemotherapy or are otherwise not eligible for conventional chemotherapy. Retinoic acids are a class of drugs related to Vitamin A, and have a wide range of effects within normal and malignant cells that affect cell growth and cell death.
Obatoclax may stop the growth of chronic lymphocytic leukemia by blocking blood flow to the cancer and by blocking some of the enzymes needed for cell growth. 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. 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 obatoclax together with fludarabine and rituximab may kill more cancer cells. This phase I trial is studying the side effects and best dose of obatoclax when given together with fludarabine and rituximab in treating patients with B-cell chronic lymphocytic leukemia.
RATIONALE: Giving chemotherapy drugs, such as cytarabine and mitoxantrone, before a donor stem cell transplant helps stop the growth of cancer cells and helps stop the patient's immune system from rejecting the donor's stem cells. When certain 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine, methotrexate, and methylprednisolone before or after transplant may stop this from happening. PURPOSE: This phase I/II trial is studying the side effects and best way to give high-dose cytarabine together with mitoxantrone in treating patients with juvenile myelomonocytic leukemia undergoing a second donor stem cell transplant.
RATIONALE: Giving chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving tacrolimus and mycophenolate mofetil before and after transplant may stop this from happening. PURPOSE: To look at the ability of umbilical cord blood cells from one or two unrelated donors to serve as a source of stem cells for people needing a bone marrow transplant.
RATIONALE: Deferasirox may be effective in treating iron overload caused by blood transfusions in patients who have undergone donor stem cell transplant. PURPOSE: This phase II trial is studying the side effects and how well deferasirox works in treating patients with iron overload after donor stem cell transplant.
The purpose of the study is to determine whether it is possible to improve the immune response rate to 'flu vaccination in patients with chronic lymphocytic leukaemia (CLL). Annual flu vaccination is recommended for all patients with CLL because they are known to be susceptible to infections and particularly to chest infections that may occur as a complication of influenza. Protection against 'flu depends on patients having a high level of antibodies against the 'flu virus. Vaccination works by stimulating the immune system and thus boosting the levels of these protective antibodies. CLL patients have weakened immune systems due to the leukaemia itself but also following chemotherapy. The exact cause of these immune defects is not known. However, CLL patients typically have low antibody levels and their immune cells may not work normally. Unfortunately, studies have shown that patients with CLL are not very good at making antibodies to 'flu vaccination and as a result protection against flu is not very reliable. Recent studies have shown that only 15-20 % of CLL patients will achieve a protective antibody level. Recently a new type of medical cream has been introduced to treat certain skin conditions. Its name is Imiquimod and it is licensed to treat viral warts in the genital area and a type of skin cancer called basal cell carcinoma. It works by increasing the immune response in the skin. Animal studies have shown that as well as increasing immunity against viruses and cancers, it increases responses to vaccination when applied at the site of vaccination. In this study we propose to test whether this new medicine can improve the response to the 'flu jab.
