Active clinical trials for "Preleukemia"

The goal of this study is to determine whether post-transplant consolidation with azacitidine combined with donor lymphocyte infusion (DLI) is a safe and effective approach for the prevention of relapse in pediatric and young adult patients with hematologic malignancies who have undergone hematopoietic stem cell transplantation (HSCT).

The main purpose of this study is to determine the safe and recommended dose of APR-246 in combination with azacitidine as well as to see if this combination of therapy improves overall survival.

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 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.

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.

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.

The purpose of this study is to confirm the safety and tolerability of oral panobinostat (PAN) in combination with a fixed dose of 5-Azacitidine (5-Aza) in adult Japanese patients with Myelodysplastic Syndromes (MDS), Chronic Myelomonocytic Leukemia (CMML) or Acute Myeloid Leukemia (AML).

The purpose of the study is to determine the maximal tolerated dose and schedule of CC-486, known as oral azacitidine, in patients with AML or MDS after allogeneic hematopoetic stem cell transplant (HSCT). HSCT is more frequently used in AML or MDS as a potential curative therapy. However, disease recurrence/relapse and graft-versus-host disease (GVHD) remain the principal causes of fatal complications after transplantation. Oral azacitidine has significant activity in MDS and AML. Oral azacitidine has also demonstrated immunomodulatory activity in AML patients after allogeneic HSCT. An oral formulation of oral azacitidine provides a convenient route of administration and an opportunity to deliver the drug over a prolonged schedule.
