Active clinical trials for "Preleukemia"

Study TLK199.2107 is a multicenter, single arm, open-label Phase 2 study of oral ezatiostat (Telintra®) in patients with lenalidomide (Revlimid®) refractory or resistant, red blood cell (RBC) transfusion-dependent, Low to Intermediate-1 IPSS risk, del5q Myelodysplastic Syndrome (MDS).

The purpose of the trial is to study how the elderly patients who have previously undergone treatment for acute myeloid leukemia and high-rRisk myelodysplastic syndromes, respond to a combined treatment with azacitidine and lenalidomide.

The goal of this clinical research study is to learn if the combination of azacitidine and GM-CSF can help to control MDS. The safety of these drugs will also be studied. Azacitidine is designed to block certain proteins that stop the function of tumor-fighting genes. By blocking the "bad" proteins, the tumor-fighting genes may be able to work better. Granulocyte-macrophage colony-stimulating factor (GM-CSF) is designed to help produce white blood cells. This may help to fight infections.

This study is being done to evaluate the safety and effectiveness of APTO-253 for the treatment of patients with the condition of acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS) for which either the standard treatment has failed, is no longer effective, or can no longer be administered safely or poses a risk for your general well being.

This pilot phase II trial studies how well a new reduced intensity conditioning regimen that includes haploidentical donor NK cells followed by the infusion of selectively T-cell depleted progenitor cell grafts work in treating younger patients with hematologic malignancies that have returned after or did not respond to treatment with a prior transplant. Giving chemotherapy and natural killer cells before a donor progenitor cell transplant may help stop the growth of cells in the bone marrow, including normal blood-forming cells (progenitor cells) and cancer cells. It may also stop the patient's immune system from rejecting the donor's cells. When the healthy progenitor cells from a related donor are infused into the patient they make 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 (called graft-versus-host disease). Removing specific T cells from the donor cells before the transplant may prevent this.

RATIONALE: Giving low-dose total-body irradiation before a donor stem cell transplant helps stop the growth of cancer cells. It also stops 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 of donor stem cell transplant after total-body irradiation and to see how well it works in treating patients with relapsed or refractory hematologic cancer or acute myeloid leukemia or acute lymphocytic leukemia in complete remission.

The hypothesis of this study is that 5-aza and lenalidomide act synergistically in MDS and AML patients with chromosomal abnormalities involving monosomy 5 or del5q. Therefore, this phase I study will investigate the maximum tolerated dose (MTD) of lenalidomide in combination with a fixed dose of 5-aza in this patient population.

The goal of this clinical research study is to find the highest tolerable dose of oxaliplatin combined with fludarabine plus cytarabine that can be given to patients with Acute Myeloid Leukemia (AML) or High-Risk Myelodysplastic Syndromes (MDS). Once the highest tolerable dose of oxaliplatin in this drug combination is found, the next goal of the study will be to learn the safety and the ability of the drug combination to control the disease.

The primary objective is to evaluate the efficacy of the treatment in response rate terms. Otherwise this study wants to evaluate the safety of the treatment.

The purpose of the study is to determine how effective azacitidine, MGCD0103, and the combination of azacitidine and MGCD0103 are in treating AML or MDS in people over 60 years of age.
