Active clinical trials for "Preleukemia"

The goal of this clinical research study is to learn if dasatinib can help to control myeloproliferative disorders. The safety and tolerability of dasatinib will also be studied.

This study primarily determined the safety and tolerability of escalating doses of vosaroxin (SNS-595) in 2 dose schedules, and assessed the PK profile of vosaroxin and defined a recommended dose regimen for Phase 2 studies. Secondarily the study assessed potential biomarkers and antileukemic activity.

RATIONALE: Giving chemotherapy, such as fludarabine, busulfan, and melphalan, before a donor peripheral stem cell transplant or bone marrow transplant helps stop the growth of cancer or abnormal 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 tacrolimus, methotrexate, mycophenolate mofetil, and antithymocyte globulin before and after transplant may stop this from happening. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer or abnormal cells as not belonging in the patient's body and destroy them (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 hematologic cancer or other diseases.

The purpose of this study is to determine whether a tablet form of azacitidine that taken by mouth is safe. This Phase I study will also look at different doses and different treatment schedules in order to better understand the effects (positive and negative) of oral azacitidine on the body and on the disease MDS, AML and CMML.

The primary objective of the trial is to assess the activity of the combined use of Valproic Acid (VPA)in combination with 5-Azacytidine (5-Aza C) in the treatment of MDS. Activity will be evaluated as percentage of patients achieving complete or partial remission.

Open label, single arm study on Deferasirox treatment in MDS patients with chronic transfusional hemosiderosis. Patients receive daily oral dosis of Deferasirox in order to eliminate the quantity of iron administered during transfusions and, if needed, to reduce the overload of already present iron. After an screening phase in which patients are evaluated according to eligibility criteria, a one year treatment phase foresees monthly visits to evaluate safety and efficacy signs.

This study will try to improve the safety and effectiveness of stem cell transplant procedures in patients with cancers of the blood. It will use a special machine to separate immune cells (T cells) from the blood of both the donor and the patient and will use photodepletion, a laboratory procedure that selectively kills cancer cells exposed to light. These special procedures may reduce the risk of graft-versus-host-disease (GVHD), a serious complication of stem cell transplants in which the donor's immune cells destroy the patient's healthy tissues, and at the same time may permit a greater graft-versus-leukemia effect, in which the donated cells fight any residual tumor cells that might remain in the body. Patients between 18 and 75 years of age with a life-threatening disease of the bone marrow (acute or chronic leukemia, myelodysplastic syndrome, or myeloproliferative syndrome) may be eligible for this study. Candidates must have a family member who is a suitable tissue match.

This single arm study will evaluate the efficacy and safety of a combination of NeoRecormon, CellCept and prednisone in patients with low or moderate risk myelodysplastic syndromes (MDS). In the first phase of the study, patients will receive CellCept (1g p.o. twice daily) plus prednisone. After 3 months, if patients have not responded to treatment, NeoRecormon (30000 IU/week, s.c.) will be added to the treatment regimen. If there is no response to NeoRecormon after 6 weeks, the dose will be increased to 60000 IU/week. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals.

The purpose of this study is to determine the effectiveness and safety of two different dose schedules of DACOGEN® (decitabine) for Injection in patients with Myelodysplastic Syndromes (MDS).

The goal of this clinical research study is to learn if combining cord blood units will be safe and result in the cells "taking" faster in recipients. The cord blood units will have their cell number increased in the lab using cells from a family member or they will be collected from an unrelated healthy donor.
