Active clinical trials for "Myelodysplastic Syndromes"

This phase I/II trial studies the side effects of glutaminase inhibitor CB-839 in combination with azacitidine in treating patients with myelodysplastic syndrome that has spread to other places in the body. Glutaminase inhibitor CB-839 and azacitidine may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

The purpose of this study is to evaluate the efficacy of treatment with azacitidine (an FDA approved drug for the treatment of MDS) and high dose ascorbic acid in patients with TET2 mutations. This approach is intended to enhance the enzymatic activity of TET2 protein, which in term may help to improve counts and symptoms, related to Myelodysplastic Syndromes and Acute Myeloid Leukemia. This combination is specific to individuals who carry this mutation.

This study evaluates the pharmacokinetics and safety of CPX-351 in patients with moderate or severe renal impairment.

This study is a phase Ib add-on study of the combination of LDE255 to azacitidine in patients without marrow response after at least 6 cycles of azacitidine.

In this study, patients will receive a myeloablative preparative regimen consisting of fludarabine and total body irradiation (TBI), followed by a T cell replete, mobilized peripheral blood stem cell (PBSC) allograft from a partially matched related donor. All patients will receive post-transplant Cy in addition to standard post transplant immunosuppression with tacrolimus and MMF. The treatment protocol will be essentially identical to the prior study, with the exception of the substitution of TBI for Busulfan. The investigators hypothesize that this change will significantly reduce the risk of HC, while maintaining the efficacy of the transplant.

A common problem after stem cell transplant is graft-versus-host-disease (GVHD). GVHD is a complication of transplantation where the donor graft attacks and damages some of your tissues. After stem cell transplant, all patients receive prophylactic medications against GVHD. In this research study, we are studying the safety and effectiveness of a bortezomib based GVHD prophylaxic drug combination in participants after myeloablative allogeneic stem call transplantation from a matched unrelated donor, mismatched related or unrelated donor.

The goal of this clinical research study is to learn if the combination of clofarabine, idarubicin, and cytarabine, or the combination of fludarabine, idarubicin, and cytarabine can help control Acute myeloid leukemia (AML) and Myelodysplastic syndromes (MDS). The safety of these study drug combinations will also be studied.

The goal of this clinical research study is to learn if omacetaxine given with cytarabine can help to control the disease in patients with AML or high-risk MDS. The safety of the study drugs will also be studied.

The main purpose of this trial is to assess the efficacy and safety of sitagliptin in enhancing engraftment following umbilical cord blood transplantation (recovery of blood counts after transplant).

Background: Several types of blood cancer are associated with poor outcomes including high-risk myelodysplastic syndromes (MDS), chronic myelomonocytic leukemia (CMML) and acute myelogenous leukemia (AML). Many people with MDS, CMML, and AML are not candidates for standard treatments. New types of treatment are needed for these cancers. Clofarabine and lenalidomide are anticancer drugs. The first damages cancer cells in the body. The second can alter blood supply to abnormal cells or affect how the immune system attacks these cells. These drugs have been previously tested as treatments for MDS and leukemia. However, they have not been tried as a combination for MDS, CMML, and AML. Researchers want to see if these drugs are safe and effective for these types of cancer. Objectives: - To test the safety and effectiveness of clofarabine and lenalidomide for people with high-risk MDS, CMML, and AML. Eligibility: Individuals at least 18 years of age who have high-risk MDS, CMML, and AML. Participants must not be candidates for standard treatments. Design: Participants will be screened with a physical exam and medical history. Blood and bone marrow samples will be collected. Participants will have 5 days of treatment with clofarabine. It will be given through a vein during an inpatient hospital stay. If there are no serious side effects after the infusion, participants will continue treatment as outpatients. After 28 days, participants will have a bone marrow biopsy to check their response to treatment. After the biopsy, participants will start lenalidomide treatment. Half of the participants will take the drug for 28 days (one treatment cycle). The other half will take it for 56 days (two cycles). More blood tests and biopsies will be used to monitor treatment. If there are no serious side effects and the disease does not become worse, participants may keep taking lenalidomide at lower doses for up to 12 more cycles.
