Active clinical trials for "Preleukemia"

RATIONALE: Vaccines made from cancer cells may help the body build an effective immune response to kill abnormal cells. PURPOSE: This clinical trial is studying how well vaccine therapy works in treating patients with myelodysplastic syndromes (MDS).

RATIONALE: Giving chemotherapy, such as fludarabine and cyclophosphamide, and total-body irradiation before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer or abnormal cells and prepares the patient's bone marrow for the 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. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer or abnormal cells (graft-versus-tumor effect). Giving an infusion of the donor's T-regulatory cells before the transplant may help increase this effect. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase I trial is studying the side effects and best dose of umbilical cord blood T-regulatory cell infusion followed by donor umbilical cord blood transplant in treating patients with high-risk leukemia or other hematologic diseases.

The purpose of this study is to assess the benefit of lonafarnib (versus placebo) in patients with myelodysplastic syndrome (MDS) or chronic myelomonocytic leukemia (CMML). Benefit will be measured by achievement of platelet transfusion independence for at least 8-consecutive weeks, and without simultaneous worsening of hemoglobin and/or need for red blood cell (RBC) transfusion. Additional endpoints will be hematologic response (which includes complete remission, partial remission, hematologic improvement), number of RBC transfusions, bleeding events, infections and safety.

To study if decitabine can help to control Myelodysplastic Syndrome (MDS) in patients who have failed on therapy with azacytidine, the current standard of therapy.

This phase I trial is studying the side effects and best dose of decitabine in treating patients with myelodysplastic syndromes or acute myeloid leukemia. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die.

Primary Objective: To determine the safety and maximum tolerated dose of CMA-676 as part of an intensive but nonmyeloablative preparative regimen in older or medically infirm patients undergoing mini-allogeneic peripheral blood stem cell transplantation Secondary Objectives: To evaluate response rates, engraftment kinetics and degree of chimerism achievable with this strategy. To evaluate disease-free and overall survival and relapse rates. To evaluate the need and ability to give multiple cycles of Mylotarg plus FA and mobilized DLI in patients not achieving complete remission.

A phase II study testing the efficacy of combined AZD1775 with AraC or single agent activity of AZD1775 in three arms: Arm A has subjects age 60 years or older who are newly diagnosed with AML receiving the combination of the drugs; Arm B has subjects who are have relapsed/refractory AML and HMA failure MDS patients being allocated to either the combination Arm B or single agent AZD1775 Arm C.

This phase I/II trial studies how well Jaktinib and azacytidine work in treating patients with myelodysplastic syndromes with myelofibrosis or myelodysplastic syndrome/myeloproliferative neoplasm with myelofibrosis. Giving Jaktinib and azacytidine may be an effective treatment for myelodysplastic syndromes with myelofibrosis or myelodysplastic syndrome/myeloproliferative neoplasm with myelofibrosis.

This research study is designed to selectively deplete CD117-positive cells from participants with AML and MDS-EB.

This trial studies the side effects of recombinant EphB4-HSA fusion protein when given together with azacitidine or decitabine in treating patients with myelodysplastic syndrome, chronic myelomonocytic leukemia, or acute myeloid leukemia that has come back or has not responded to previous treatment with a hypomethylating agent. Recombinant EphB4-HSA fusion protein may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Hypomethylating agents, such as azacitidine and decitabine, slow down genes that promote cell growth and can kill cells that are dividing rapidly. Giving recombinant EphB4-HSA fusion protein together with azacitidine or decitabine may work better in treating patients with myelodysplastic syndrome, chronic myelomonocytic leukemia, or acute myeloid leukemia.
