Active clinical trials for "Myelodysplastic Syndromes"

This phase I trial tests the safety, side effects, and best dose of uproleselan in combination with fludarabine and cytarabine in treating patients with acute myeloid leukemia, myelodysplastic syndrome or mixed phenotype acute leukemia that has come back (relapsed) or does not respond to treatment (refractory) and that expresses E-selectin ligand on the cell membrane. Uproleselan binds to E-selectin expressed on endothelial cells of the bone marrow and prevents their interaction with selectin-E ligand-expressing cancer cells. This may prevent leukemia cells from being sequestered in the bone marrow niche and escaping the effect of chemotherapy. Chemotherapy drugs, such as fludarabine and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving uproleselan in combination with fludarabine and cytarabine may enhance their activity.

Background: The myelodysplastic syndromes (MDS) are a group of bone marrow neoplasms. MDS mostly affect elderly people. The drugs used to treat MDS are not always effective, and the only curative treatment is stem cell transplant. Researchers want to see if a new drug can be used to treat MDS. Objective: To learn if BMS-986253 is a safe and effective treatment for MDS. Eligibility: Adults aged 18 and older with MDS. Design: Participants will be screened with a medical history, medication review, and physical exam. They will answer questions about how well they are able to take care of themselves. Their temperature, blood pressure, breathing rate, and heart rate will be monitored. They will have an electrocardiogram to see how well their heart is working. They will give blood and urine samples. They may have a bone marrow biopsy. Participants will be assigned to a specific group. They will receive either BMS-986253 alone or in combination with DNA methyltransferase inhibitors (DNMTi). Treatment will be given in 28-day cycles. Participants will get BMS-986253 as an infusion on days 1 and 15 of each cycle. Some participants also will take oral DNMTi on days 2-6 of each cycle. They will receive treatment until their disease gets worse or they have bad side effects. At study visits, some screening tests will be repeated. Some of the samples that are collected will be used for genetic testing. About 30 days after treatment ends, participants will have a follow-up visit to see how they are doing. After that, follow up will occur via phone every 3-6 months until the study ends. NIH will cover the costs for some travel expenses....

This study seeks to examine treatment therapy that will reduced regimen-related toxicity and relapse while promoting rapid immune reconstitution with limited serious graft-versus-host-disease (GVHD) and also improve disease-free survival and quality of life. The investigators propose to evaluate the safety and efficacy of selective naive T-cell depleted (by TCRɑβ and CD45RA depletion, respectively) haploidentical hematopoietic cell transplant (HCT) following reduced intensity conditioning regimen that avoids radiation in patients with hematologic malignancies that have relapsed or are refractory following prior allogeneic transplantation. PRIMARY OBJECTIVE: To estimate engraftment by day +30 post-transplant in patients who receive TCRɑβ-depleted and CD45RA-depleted haploidentical donor progenitor cell transplantation following reduced intensity conditioning regimen without radiation. SECONDARY OBJECTIVES: Assess the safety and feasibility of the addition of Blinatumomab in the early post-engraftment period in patients with CD19+ malignancy. Estimate the incidence of malignant relapse, event-free survival, and overall survival at one-year post-transplantation. Estimate incidence and severity of acute and chronic (GVHD). Estimate the rate of transplant related mortality (TRM) in the first 100 days after transplantation.

This phase II trial studies how well ruxolitinib phosphate and azacytidine work in treating patients with myelofibrosis or myelodysplastic syndrome/myeloproliferative neoplasm. Ruxolitinib phosphate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as azacytidine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ruxolitinib phosphate and azacytidine may be an effective treatment for myelofibrosis or myelodysplastic syndrome/myeloproliferative neoplasm.

This phase I trial studies the side effects and the best dose of intensity modulated total marrow irradiation (IMTMI) when given together with fludarabine phosphate and melphalan in treating patients with cancers of the blood (hematologic) that have returned after a period of improvement (relapsed) undergoing a second donor stem cell transplant. IMTMI is a type of radiation therapy to the bone marrow that may be less toxic and may also reduce the chances of cancer to return. Giving fludarabine phosphate, melphalan, and IMTMI before a donor stem cell transplant may help stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. It may also 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.

Background: - Researchers want to develop better ways to treat cancer. In this study, they will give people with cancer two drugs. These drugs have been used on their own to treat some blood cell cancers. Objectives: - To test the safety and efficacy of the drug combination of bortezomib and clofarabine. Eligibility: - Adults age 18 and over with advanced cancer that has progressed after receiving standard treatment or that has no effective therapy. Design: Participants will be screened with medical history, physical exam, and scans to measure their tumors. They will also have heart, blood, and urine tests. All of these may be done by their regular doctors. Participants will get the study drugs in 21-day cyles. They will stay at the clinic for week 1 of every cycle, then have 2 weeks off. <TAB>- Bortezomib will be injected under the skin on days 1 and 4. <TAB>- Clofarabine will be injected in a vein for days 1-5. During cycle 1 only, participants will go to the clinic or their doctor to have a physical exam and blood tests at the start of the second and third week. Participants will have clinical evaluations throughout the study, including before receiving treatment and then before the start of each cycle. Participants may stay in the study as long as they are tolerating the drugs and their tumor is not getting worse. Participants will have follow-up for 30 days after the last dose of study drugs. The first part of this study tests the safety of different doses of clofarabine and bortezomib. The second part of this study involves a separate group of participants who will undergo mandatory research biopsies to learn more about the effects of clofarabine and bortezomib on cancer cells.

Background: Stem cell transplants from related donors (allogenic stem cell transplants) can be used to treat individuals with certain kinds of severe blood diseases or cancers, such as severe anemia. Allogenic stem cell transplants encourage the growth of new bone marrow to replace that of the recipient. Because stem cell transplants can have serious complications, researchers are interested in developing new approaches to stem cell transplants that will reduce the likelihood of these complications. By reducing the number of white blood cells included in the blood taken during the stem cell collection process, and replacing them with a smaller amount of white blood cells collected prior to stem cell donation, the stem cell transplant may be less likely to cause severe complications for the recipient. Researchers are investigating whether altering the stem cell transplant donation procedure in this manner will improve the likelihood of a successful stem cell transplant with fewer complications. Objectives: - To evaluate a new method of stem cell transplantation that may reduce the possibly of severe side effects or transplant rejection in the recipient. Eligibility: Recipient: Individuals between 4 and 80 years of age who have been diagnosed with a blood disease that can be treated with allogenic stem cell transplants. Donor: Individuals between 4 and 80 years of age who are related to the recipient and are eligible to donate blood. OR unrelated donors found through the National Marrow Donor Program. Design: All participants will be screened with a physical examination and medical history. DONORS: Donors will undergo an initial apheresis procedure to donate white blood cells. After the initial donation, donors will receive injections of filgrastim to release bone marrow cells into the blood. After 5 days of filgrastim injections, donors will have apheresis again to donate stem cells that are present in the blood. RECIPIENTS: Recipients will provide an initial donation of white blood cells to be used for research purposes only. From 7 days before the stem cell transplant, participants will be admitted to the inpatient unit of the National Institutes of Health Clinical Center and will receive regular doses of cyclophosphamide, fludarabine, and anti-thymocyte globulin to suppress their immune system and prepare for the transplant. After the initial chemotherapy, participants will receive the donated white blood cells and stem cells as a single infusion. After the stem cell and white blood cell transplant, participants will have regular doses of cyclosporine and methotrexate to prevent rejection of the donor cells. Participants will have three doses of methotrexate within the week after the transplant, but will continue to take cyclosporine for up to 4 months after the transplant. Participants will remain in inpatient care for up to 1 month after the transplant, and will be followed with regular visits for up to 3 years with periodic visits thereafter to evaluate the success of the transplant and any side effects.

RATIONALE: Giving chemotherapy, such as busulfan, fludarabine, and melphalan, before a donor umbilical cord blood stem cell transplant helps stop the growth of abnormal or cancer 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil may stop this from happening. PURPOSE: This phase II trial is studying how well combination chemotherapy followed by a donor umbilical cord blood transplant works in treating infants with high-risk acute leukemia or myelodysplastic syndromes.

The goal of this clinical trial is to compare outcomes of two reduced intensity conditioning (RIC) regimens (fludarabine plus busulfan and fludarabine plus melphalan) in allogeneic hematopoietic stem cell transplantation (HSCT) for acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) patients. The main questions it aims to answer are: The safety of two reduced intensity conditioning (RIC) regimens (fludarabine plus busulfan and fludarabine plus melphalan) in allogeneic hematopoietic stem cell transplantation for adult AML/MDS patients with HCT-CI≥3 or aged ≥55 years. The efficacy of two reduced intensity conditioning (RIC) regimens (fludarabine plus busulfan and fludarabine plus melphalan) in allogeneic hematopoietic stem cell transplantation for adult AML/MDS patients with HCT-CI≥3 or aged ≥55 years. Participants will be randomized to one of two reduced intensity conditioning (RIC) regimens (fludarabine plus busulfan and fludarabine plus melphalan)

The goal of this interventional study is to evaluate if pre-emptive intervention using Azacitidine and / or donor lymphocytes or tapering of immune suppression in measurable residual disease (MRD) positive subjects can prevent clinical relapse. Participants will undergo MRD surveillance and be subjected to intervention in case of MRD positivity. Results will be compared with NMDSG14B, part one, in which MRD was analyzed in included patients without recieving intervention.
