Active clinical trials for "Myelodysplastic Syndromes"

RATIONALE: Giving chemotherapy, natural killer cells, aldesleukin, and total-body irradiation before a donor umbilical cord blood stem cell transplant helps stop the growth of abnormal cells and cancer 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 cyclosporine, mycophenolate mofetil, and methylprednisolone before and after transplant may stop this from happening. PURPOSE: This clinical trial is studying how well giving fludarabine and cyclophosphamide together with total-body irradiation followed by donor umbilical cord blood natural killer cells, aldesleukin, and umbilical cord blood transplant works in treating patients with refractory hematologic cancer or other diseases.

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 test the hypothesis that a pre-infusion preparative regimen of cyclophosphamide and fludarabine will improve the effectiveness of DLI in patients with blood cancers.

Patients with Acute Myelogenous Leukemia or Myelodysplastic are able to achieve a complete remission but fail to achieve a prolonged disease-free survival. High dose chemotherapy and autologous bone marrow transplantation has been shown to be effective in this group of patients but hematopoietic recovery is slow, and infectious or bleeding complications are common. The delay in hematopoietic recover is accentuated by the use of purging techniques. This is a novel purging approach for autologous stem cell transplantation in patients with Acute Myelogenous Leukemia or Myelodysplastic syndrome to allow for rapid engraftment with a lower relapse rate therefore improving the therapeutic outcomes

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.

This study compares the safety and effectiveness of giving rivogenlecleucel (BPX-501 T cells) to patients with AML or MDS post haploidentical hematopoietic stem cell transplant compared to post-transplant cyclophosphamide.

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.
