Active clinical trials for "Leukemia"

The purpose of this study is to evaluate whether patients with previously untreated, early stage CLL respond to empirical broad spectrum antibiotics and therefore test the hypothesis that occult bacterial infections are involved in the induction and maintenance of CLL.

Allogeneic transplant from a matched sibling for the treatment of a variety of illnesses including bone marrow failure states, leukemias, myelodysplastic or myeloproliferative syndromes, lymphoma, or myeloma using a nonmyeloablative preparative regimen.

This study is designed to determine the maximal tolerated dose of Ruxolitinib in combination with nilotinib in patients with chronic myeloid leukemia (CML).

Multicentric evaluation of the reduction of unrelated cord blood transplantation (UCBT) toxicity by using reduced intensity conditioning (RIC) in patients with acute myeloid leukaemia.UCBT related mortality and morbidity were limiting factors for the development of this procedure in adults. Non myeloablative conditioning regimen showed promising results and prospective evaluation has to be developed to confirm these retrospective data.

The purpose of this study is to investigate if intramuscular PEG-asparaginase administered either at six or two week intervals from day 92 until 8 months from diagnosis for patients with non-HR ALL will result in equal probability of Event Free Survival

As one of the nation's largest cooperative cancer treatment groups, the Alliance for Clinical Trials in Oncology (Alliance) is in a unique position to organize a Leukemia Tissue Bank. The member institutions diagnose hundreds of patients with leukemia or myelodysplastic syndrome each year, and uniformly treat these patients with chemotherapy regimens. The Alliance offers centralized data management for the clinical history, the classification of the leukemia and myelodysplastic syndrome, cytogenetics, flow cytometric analysis, treatment and follow-up. The highly skilled health care providers at each member institution are familiar with obtaining informed consent, completing data questionnaires and shipping specimens. There currently exists a central processing facility where samples are prepared for a variety of cellular and molecular studies. Hence, the patient resources, the health care providers, and a processing facility for a Leukemia Tissue Bank are all in place. What is needed, however, and is addressed in the current protocol, is a formal mechanism to procure bone marrow, blood and normal tissue from patients with hematologic malignancies who are to be enrolled on Alliance (Cancer and Leukemia Group B [CALGB]) treatment studies.

The primary purpose of the study is to determine, whether the addition of 5-azacytidine to standard chemotherapy in elderly patients with newly diagnosed AML improves treatment results (event free survival).

There is no curative therapy once acute leukemia patients relapse after transplant. Patients who develop clinically significant graft versus host disease (GVHD) have a lower rate of relapse than those who do not develop GVHD. We are initiating this study of post-transplant fast withdrawal of immunosuppression and donor lymphocyte infusions, with a goal of achieving full donor chimerism in children with hematologic malignancies. If our hypothesis that full donor chimerism results in leukemia-free survival is correct, using immune modulation to achieve full donor chimerism should decrease relapse rate and thus increase survival. The goal of this Phase II study is to identify if achieving full donor chimerism in whole blood CD3+ and leukemia-specific (CD14/15+, CD19+, CD33+ and CD34+) subset may decrease the risk of relapse of patients undergoing allogeneic transplant for hematologic malignancy.

First randomization: After inclusion Use of Daunorubicin (arm D) or Idarubicin (arm I) as anthracyclin during all courses of chemotherapy (induction, consolidation courses before ASCT) Second randomization: After achieving 1st CR: all patients received non intensive consolidation course Familial HLA typing required for all patients Patients with HLA-identical sibling: Patients with very good prognostic factors (CBF leukemias, WBC < 30 giga/l at diagnosis, 1st CR after one induction course) = arm C: no allogeneic stem cell transplantation in 1st CR; received 2 more courses of intensive consolidation chemotherapy All others patients received an allogeneic transplant For patients aged less than 51 = arm M: upfront myeloablative conditioning regimen For patients aged over 51 and less than 61= arm m: intensive chemotherapy consolidation course.

The purpose of this research study is to determine if plerixafor can make CLL/SLL (Chronic Lymphocytic Leukemia/ Small Lymphocytic Lymphoma) cells more sensitive to being killed by rituximab, an anti-cancer drug that is commonly used in treating CLL and SLL. In this study, plerixafor will be added to standard treatment with rituximab. Subjects will be monitored to see how well they tolerate the use of these drugs together and how well they work to treat the leukemia. The primary objective is to determine the maximum tolerated dose (MTD) of plerixafor when combined with rituximab as treatment for previously treated patients with CLL or SLL.
