Filter by:RATIONALE: 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, such as fludarabine and busulfan, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. A peripheral stem cell, bone marrow , or umbilical cord blood transplant may be able to replace blood-forming cells that were destroyed by chemotherapy. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine together with methotrexate and methylprednisolone may stop this from happening. PURPOSE: This phase II trial is studying how well giving alemtuzumab together with fludarabine and busulfan works when given before donor stem cell transplant in treating young patients with hematologic disorders.
RATIONALE: Antibiotics, such as daptomycin and vancomycin, may be effective in treating bacteria in the blood. It is not yet known whether daptomycin is more effective than vancomycin in treating bacteria in the blood in patients with neutropenia caused by chemotherapy. PURPOSE: This randomized clinical trial is studying daptomycin to see how well it works compared with vancomycin in treating bacteria in the blood in patients with neutropenia caused by chemotherapy.
RATIONALE: Giving chemotherapy and total body irradiation before a donor bone marrow transplant or peripheral blood stem cell transplant helps stop the growth of cancer cells. It also 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 antithymocyte globulin and removing the T cells from the donor cells before transplant may stop this from happening. PURPOSE: This phase I trial is studying the side effects and best dose of donor T cells and antithymocyte globulin when given together with chemotherapy and total-body irradiation in treating young patients who are undergoing T-cell depleted donor stem cell transplant for myelodysplastic syndrome, leukemia, bone marrow failure syndrome, or severe immunodeficiency disease.
This is an open-label study of MK0991 in children between 3 to 24 months of age with new onset fever and neutropenia. The purpose of the study is to investigate plasma drug levels of caspofungin.
The purpose of this study is to assess pegfilgrastim starting with the first cycle versus secondary prophylaxis on neutropenic events (including neutropenia +/- fever, dose delays, dose reductions, and hospitalizations) in older patients receiving chemotherapy.
Severe aplastic anemia (SAA) is a life-threatening bone marrow failure disorder characterized by pancytopenia and a hypocellular bone marrow. Allogeneic bone marrow transplantation offers the opportunity for cure in 70% of patients, but most patients are not suitable candidates for hematopoietic stem cell transplantation (HSCT) due to advanced age or lack of a histocompatible donor. For these patients, comparable long term survival is attainable with immunosuppressive treatment with anti-thymocyte globulin (ATG) and cyclosporine (CsA). However, of those patients treated with horse ATG(h-ATG)/CsA, one quarter to one third will not respond, and about 50% of responders relapse. Auto-reactive T cells may be resistant to the effect of ATG/CsA (non-responders), while in others residual auto-reactive T cells expand post-treatment, leading to hematopoietic stem cell destruction and recurrent pancytopenia (relapse). As long term survival is correlated to response rates and robustness of hematopoietic recovery, novel immunosuppressive regimens that can achieve hematologic response and decrease relapse rates are needed. This trial will compare the effectiveness of three immunosuppressive regimens as first line therapies in patients with SAA with early hematologic response as the primary endpoint, as well as assess the role of extended CsA treatment after h-ATG in reducing numbers of late events of relapse and clonal evolution. Randomization is employed to obtain an equal distribution of subject to each arm; comparisons of early hematologic responses will be made among the rates observed among the three concurrent arms (rabbit-ATG [r-ATG] versus standard h-ATG; alemtuzumab vs standard h-ATG). For long course CSA, comparison of primary end points will be to well established historic relapse rate of 38% at 2-3 years and a cumulative rate of clonal evolution of 15%. In the original design subjects were randomized to one of three different regimens: h-ATG + 6 months CsA followed by an 18 month CsA taper; r-ATG + 6 months CsA; or alemtuzumab (Campath). Subjects failing to respond to r-ATG will be crossed over to alemtuzumab (Campath), and subjects failing alemtuzumab (Campath) will be crossed over to r-ATG. Subjects failing to respond to h-ATG + CsA taper will go off study and be evaluated for eligibility for a second course of immunosuppression on companion protocol 03-H-0249, which similarly randomizes subjects between r-ATG and alemtuzumab (Campath) as salvage therapy. The Campath arm closed to new accrual for lack of efficacy on 4/10/2008. New accruals will be randomized to h-ATG + 6 months CsA followed by an 18 month CsA taper or r-ATG + 6 months CsA. Subjects failing to respond to r-ATG will continue to be crossed over to alemtuzumab (Campath ). Subjects failing to respond to h-ATG + CsA taper will go off study and be evaluated for eligibility for a second course of immunosuppression on companion protocol 03-H-0249, which similarly randomizes subjects between r-ATG and alemtuzumab (Campath ) as salvage therapy. The primary endpoint will be hematologic respnse, defined as no longer meeting criteria for SAA, at 6 months. Secondary endpoints are relapse, robustness of hematologic recovery at 6 months, response at 3 and 12 months, survival, clonal evolution to PNH, myelodysplasia and acute leukemia. Long-course CSA will be assessed separately for its efficacy in reducing late events of relapse and evolution by comparison to historical control data.
Evaluate if tobramycin given once a day is at least as efficacious as the traditional tobramycin given three times a day, given with penicillin G, til patients with febrile neutropenia.
To determine the clinical effects of garlic in preventing and treatment of patients with chemotherapy related febrile neutropenia.These patients have a very high incidence of infections which are not routinely covered by the standard empiric therapy. Adding a non- toxic and possibly effective therapy may reduce the risk for infections, synergize the empiric antibiotic treatment and may lessen the need for broader spectrum and more severe side effects.
Prevention trial of nosocomial infections in neutropenic prematures with G-CSF
This study is designed to test two separate strategies for treatment of anemia (low hemoglobin) and neutropenia (low white blood cells) in HIV/HCV coinfected patients who are being treated with pegylated interferon and ribavirin.
