Filter by:Patients with chemo refractory CLL have a poor prognosis. 2 independent mechanisms are attributed to the development of chemoresistance in CLL. The first is a shift in the balance between pro- and anti-apoptotic regulators. The second mechanism is based on acquired mutations resulting in a dysfunctional p53 response. Recent studies indicate that the tyrosine kinase inhibitor dasatinib acts synergistically with both purine analogies and alkylating agents. Also, dasatinib has the potency to restore the apoptotic balance of CLL cells. Hypothesis: Dasatinib will be clinically active in chemo-refractory CLL patients and will act synergistically with the purine-analogue fludarabine.
Primary study objective is the evaluation of efficacy of autologous hematopoietic cell transplantation (HCT) with core-binding factor (CBF) positive acute myeloid leukemia (AML) in the first CR (CR1) in terms of relapse incidence (cumulative incidence of relapse, CIR) and disease-free survival (DFS). Secondary study objectives are the engraftment rate / time to engraftment, transplantation-related mortality (TRM) rate, event-free survival (EFS) rate, and Overall survival (OS).
RATIONALE: Drugs used in chemotherapy, such as clofarabine, daunorubicin hydrochloride, cytarabine, and decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells. It is not yet known which chemotherapy regimen is more effective in treating acute myeloid leukemia. PURPOSE: This randomized phase III trial is studying clofarabine to see how well it works compared with daunorubicin hydrochloride and cytarabine when followed by decitabine or observation in treating older patients with newly diagnosed acute myeloid leukemia.
This is a single-center, single arm, open-label study of oral lenalidomide monotherapy administered to red blood cell (RBC) transfusion dependent adult subjects with Diamond-Blackfan Anemia (DBA). Primary Objective: To evaluate the erythroid response rate as measured by rate of red blood cell transfusion independence (MDS IWG 2000 Criteria will be applied) Secondary Objective: 1)To evaluate the tolerability and safety profile of lenalidomide in patients with DBA and other inherited marrow failure syndromes 2) To correlate response to lenalidomide with biologic surrogates of DBA including ribosomal protein mutation status, ex vivo erythroid colony growth, and microarray gene expression
RATIONALE: Valproic acid may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. It may also help cancer cells become more like normal cells, and grow and spread more slowly. PURPOSE: This phase II trial is studying how well valproic acid works in treating patients with previously treated non-Hodgkin Lymphoma, Hodgkin lymphoma, or chronic lymphocytic leukemia.
The purpose of this study is to determine the safety and feasibility of unrelated double umbilical cord blood units Transplantation in patients with haematological malignancies using Antithymocyte Globulin Cyclophosphamide, busulfan as conditioning and cyclosporin, methylprednisolone as GVHD prophylaxis.
The main objective of this project is not only a better understanding of the human leukemic disease but also to find new anti-leukemic or improve existing ones. This study has, the following aims: - To analyze the genetic and epigenetic regulation of the retinoic acid induced cascade which leads to the expression of TRAIL in blood cells of patients with acute leukemia. This study will be complemented by the analysis of global gene expression (DNA chips) and of the DNA methylation state, and by chromatin immunoprecipitation experiences. - To determine the efficiency of inhibitors of enzymes responsible for the modification of chromatin (existing and new developments within the European consortium EPITRON coordinated by Dr Gronemeyer) as inducers of differentiation and / or apoptosis of leukemic blasts. - To explore Ikaros genic and functional abnormalities (genomic deletions, mutations, abnormal transcripts and proteins) in acute leukemia. The aim is to determine if these abnormalities may play a prognosis role.
Identification of alterations potentially involved in the complex mechanisms of leukemogenesis and at the identification and validation of novel biological factors which may serve as predictors of drug-response and drug-resistance or which may be suitable for targeted therapy.
Background: The development of new technologies now allow scientists to investigate the molecular basis and clinical manifestations of monoclonal B cell lymphocytosis (MBL), chronic lymphocytic leukemia(CLL)/small lymphocytic lymphoma (SLL), lymphoplasmacytic lymphoma (LPL)/Waldenstrom macroglobulinemia (WM), and splenic marginal zone lymphoma (SMZL). Applying these methods in a natural history study can clarify processes involved in disease progression and possibly lead to the discovery or validation of treatment targets. - Objectives: - Study the history of MBL/CLL/SLL/LPL/WM/SMZL in patients prior to and after treatment. - Characterize clinical, biologic and molecular events of disease stability and progression of patients enrolled on this protocol. - Eligibility: - Diagnosis of MBL/CLL/SLL/LPL/WM/SMZL - Age greater than or equal to 18 years. - Patients with CLL/SLL in remission after chemotherapy are excluded. - ECOG performance status of 0-2. - Design: - Patients are typically followed every 6 to 24 months in the clinic and have blood drawn. When required patients may undergo additional testing that may include bone marrow biopsy and aspiration, blood drawing, lymph node biopsy, x-ray studies, positron emission tomography and CT and MRI scans. Some of these tests may be required to monitor CLL/SLL, LPL/WM, and SMZL patients. Other tests, such as bone marrow biopsy and aspiration, lymph node biopsy, may not be clinically indicated, but patients may be asked to undergo these procedures for research purposes. - No treatment will be administered on this study. If a patients requires treatment for their cancer, available NIH clinical trials and alternative treatment options will be discussed with the patient.
The purpose of the present study is to develop a biological prognostic index in patients with Binet stage A Chronic Lymphocytic Leukemia (CLL) who do not necessitate therapy according to NCI guidelines and to prospectively validate the proposed score system based on the absence/presence of 1, 2 or 3 unfavorable prognostic markers such as cluster of differentiation 38 (CD38) expression, Zap-70 expression and immunoglobulin heavy chain variable region (IgVH) configuration.
