Active clinical trials for "Preleukemia"

Allogeneic stem cell transplantation (transplant of blood cells from another individual) is a treatment option for patients with myelodysplasia or myeloproliferative Disorders. During the course of this study, it will be evaluated whether a particular type of blood cell, called a cytokine-induced killer (CIK) cell, may add benefit to allogeneic stem cell transplantation. CIK cells are present in small quantities in the bloodstream but their numbers can be expanded after a brief period of nurturing in a laboratory.

Primary Outcome Measures: • To evaluate the efficacy of treatment with Azacitidine in patients with transfusion-dependent, low risk International Prognostic Scoring System (IPSS) 0 int-1, Myelodysplastic Syndrome (MDS) without chromosome 5 (5q) deletion. The main objective will be based on the erythroid haematologic response according to International Working Group (IWG) 2006 criteria. Secondary Outcome Measures: Haematologic response, bases on the following parameters: platelets, and neutrophils according to International Working Group (IWG) Criteria. Medullary and cytogenetic response according to International Working Group (IWG) 2006 criteria. The effect of treatment response on quality of life, through the Functional Assessment of Cancer Therapy-Anemia (FACT-an) questionnaire. Overall survival, Event-Free Survival and the Acute Leukaemia Transformation Rate.

This study has been designed to investigate the safety and feasibility of using a chemotherapy drug, Clofarabine, to reduce the disease burden before a donor transplant, in patients with high risk Acute Myeloid Leukaemia or Myelodysplasia (MDS). In this study Clofarabine chemotherapy will be given a few days before a reduced or full intensity donor stem cell transplant and without waiting for normal blood counts to recover. It is hoped that this approach may improve the outcome for patients with high risk AML and MDS after their transplant.

The primary purpose of this study is to evaluate the pharmacokinetics of oral azacitidine when administered once daily as two 150-mg tablets, including the effect of food, and to evaluate the bioavailability of oral azacitidine 300-mg when administered as two 150-mg tablets relative to three 100-mg tablets.

The purpose of this study is to see if Panobinostat is safe to give to patients and to determine the best dose to give in combination with standard cytarabine and daunorubicin chemotherapy.

The goal of this clinical research study is to learn if clofarabine when given in combination with cytarabine can help to control myelodysplastic syndrome (MDS) after the disease could not be controlled with standard therapy. The safety of this treatment will also be studied. Clofarabine is designed to interfere with the growth and development of cancer cells. Cytarabine is designed to insert itself into DNA (the genetic material of cells) of cancer cells and stop the DNA from repairing itself.

This phase II trial studies how well azacitidine works in treating patients with relapsed myelodysplastic syndrome (MDS), chronic myelomonocytic leukemia (CMML), or acute myeloid leukemia (AML) who have undergone stem cell transplant. Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing.

This phase II trial studies how well giving treosulfan together with fludarabine phosphate and total-body irradiation (TBI) works in treating patients with hematological cancer who are undergoing umbilical cord blood transplant (UCBT). Giving chemotherapy, such as treosulfan and fludarabine phosphate, and TBI before a donor UCBT helps stop the growth of cancer cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the stem cells from a related or unrelated donor, that do not exactly match the patient's blood, 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 also make an immune response against the body's normal cells. Giving cyclosporine (CsA) and mycophenolate mofetil (MMF) after the transplant may stop this from happening.

RATIONALE: Giving low doses of chemotherapy and antithymocyte globulin before a donor stem cell transplant helps stop the growth of abnormal 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 abnormal cells (graft-versus-tumor effect). PURPOSE: This phase II trial is studying how well a donor stem cell transplant works after busulfan, fludarabine, methylprednisolone, and antithymocyte globulin in treating patients with bone marrow failure syndrome.

The purpose of this research study is to determine if the GM-K562/leukemia cell vaccine can be safely given soon after allogeneic marrow or blood stem cell transplant. The GM-K562/leukemia cell vaccine is composed of a cultured cell line that has been genetically modified to secrete GM-CSF, a naturally occuring substance in the body that stimulates the immune system. The vaccine is a mixture of the GM-K562 cells (radiated to prevent them from growing in the participants body) with the participant's previously frozen and killed leukemia cells. By mixing the GM-K562 with the leukemia cells, we would like to study whether this vaccine combination will stimulate the participant's new immune system to recognize and fight against their MDS/AML cancer cells.
