Active clinical trials for "Myelodysplastic Syndromes"

The goal of this clinical research study is to determine the effectiveness of alemtuzumab in patients with aplastic anemia, MDS, or T-Cell large granular lymphocytic leukemia. The safety of alemtuzumab will also be studied.

The goal of the Phase I part of this clinical research study is to find the highest safe dose of bendamustine that can be given to patients with acute myelogenous leukemia (AML), Acute lymphoblastic leukemia (ALL), Chronic myelogenous (or myeloid) leukemia (CML) in blastic phase, Chronic Myelomonocytic Leukemia (CMML), and myelodysplastic syndromes (MDS). The goal of the Phase II part of this clinical research study is to learn if bendamustine can help to control AML, ALL and MDS. The safety of this drug will continue to be studied.

This study will be used to determine the maximum tolerated dose of oral clofarabine when administered daily for 14 consecutive days repeated every 21 days.

RATIONALE: Giving total marrow and total lymph node irradiation together with low doses of chemotherapy before a donor stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). PURPOSE: This phase I trial is studying the side effects and best dose of total marrow and total lymph node irradiation when given together with fludarabine and melphalan followed by donor stem cell transplant in treating patients with advanced hematological cancer that has not responded to treatment.

RATIONALE: Giving chemotherapy, such as busulfan and fludarabine phosphate, before a peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving methotrexate, tacrolimus, and antithymocyte globulin before and after the transplant may stop this from happening. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them (called graft-versus-tumor effect). Giving an infusion of the donor's white blood cells (donor lymphocyte infusion) may boost this effect. PURPOSE: This phase II trial is studying how well donor stem cell transplant works in treating patients with relapsed hematologic malignancies or secondary myelodysplasia previously treated with high-dose chemotherapy and autologous stem cell transplant .

Patients with hematologic malignancies will receive myeloablative chemotherapy followed by stem cell rescue with bone marrow or hematopoietic peripheral blood stem cells collected by apheresis from a filgrastim- (G-CSF)-mobilized haploidentical related-donor, ie, hematopoietic peripheral blood stem cell transplant (HSCT).

RATIONALE: Giving low doses of chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). PURPOSE: This phase I trial is studying the safety of donor umbilical cord blood transplant after fludarabine phosphate, cyclophosphamide, and total-body irradiation in treating patients with high-risk hematologic cancer (now closed). The Phase II part of this trial is studying whether priming one of two UCB units with C3a facilitates engraftment of the treated unit.

The primary purpose is to determine the ability of CD34+ selection and T cell depletion using the CliniMACS® device to prevent severe acute graft-versus-host disease (GVHD) in patients receiving a stem cell transplant from an alternative (unrelated and mismatched related) donor. The secondary objectives include evaluation of engraftment, immune recovery, and post-transplant infections. Patients requiring stem cell transplants for either malignant (cancerous) or non-malignant disease will be included in the study. The recipients will be grouped into one of two groups based on whether the donor is mismatched related (Cohort A) or unrelated (Cohort B). The patient will receive a conditioning regimen including chemotherapy drugs and/or total body irradiation based on the disease for which the transplant is performed.

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 International Working Group (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

This study assessed the efficacy and safety of LBH589 as single agent and in combination with ESA in red blood cell transfusion-dependent Low and Int-1 MDS patients being either refractory to ESA or with a low probability of response. The study had a non-randomized core phase followed by a randomized phase.
