Active clinical trials for "Myelodysplastic Syndromes"

Allogeneic transplant from a matched sibling for the treatment of a variety of illnesses including bone marrow failure states, leukemias, myelodysplastic or myeloproliferative syndromes, lymphoma, or myeloma using a nonmyeloablative preparative regimen.

The purpose of this study is to investigate whether infusion of G-CSF mobilized HLA-mismatched peripheral blood stem cells (G-PBSC) combining decitabine and cytarabine chemotherapy can improve outcomes in myelodysplastic syndromes (MDS) patients.

This is a dose escalation followed by dose expansion study of TL32711 in combination with 5-Azacitidine in subjects with Myelodysplastic syndrome who are naïve, have relapsed or have failed prior 5-azacitidine therapy. Pre-clinical and mechanistic studies support that 5-Azacitidine may modulate pathways that enable birinapant-mediated anti-tumor activity.

This is a phase II multi-institutional therapeutic study of NK-cell based nonmyeloablative haploidentical transplantation for the treatment of high-risk acute myeloid diseases. Enrollment will use a two-stage design. Stage 1 will enroll 15 patients unless an early stopping rule is met. If 9 or more of these first 15 patients achieve leukemia free neutrophil engraftment at day +28 accrual will move to stage 2. In stage 2, an additional 28 patients will be enrolled for a total of 43 patients. Patients will be followed for disease response for 2 years.

As one of the nation's largest cooperative cancer treatment groups, the Alliance for Clinical Trials in Oncology (Alliance) is in a unique position to organize a Leukemia Tissue Bank. The member institutions diagnose hundreds of patients with leukemia or myelodysplastic syndrome each year, and uniformly treat these patients with chemotherapy regimens. The Alliance offers centralized data management for the clinical history, the classification of the leukemia and myelodysplastic syndrome, cytogenetics, flow cytometric analysis, treatment and follow-up. The highly skilled health care providers at each member institution are familiar with obtaining informed consent, completing data questionnaires and shipping specimens. There currently exists a central processing facility where samples are prepared for a variety of cellular and molecular studies. Hence, the patient resources, the health care providers, and a processing facility for a Leukemia Tissue Bank are all in place. What is needed, however, and is addressed in the current protocol, is a formal mechanism to procure bone marrow, blood and normal tissue from patients with hematologic malignancies who are to be enrolled on Alliance (Cancer and Leukemia Group B [CALGB]) treatment studies.

There is no curative therapy once acute leukemia patients relapse after transplant. Patients who develop clinically significant graft versus host disease (GVHD) have a lower rate of relapse than those who do not develop GVHD. We are initiating this study of post-transplant fast withdrawal of immunosuppression and donor lymphocyte infusions, with a goal of achieving full donor chimerism in children with hematologic malignancies. If our hypothesis that full donor chimerism results in leukemia-free survival is correct, using immune modulation to achieve full donor chimerism should decrease relapse rate and thus increase survival. The goal of this Phase II study is to identify if achieving full donor chimerism in whole blood CD3+ and leukemia-specific (CD14/15+, CD19+, CD33+ and CD34+) subset may decrease the risk of relapse of patients undergoing allogeneic transplant for hematologic malignancy.

Chromosomal analysis or the study of genetic differences in patients previously untreated with AML, ALL, MDS or MM may be helpful in the diagnosis and classification of disease. It may also improve the ability to predict the course of disease and the selection of therapy. Institutions must have either an Alliance-approved cytogeneticist or an agreement from an Alliance-approved main member cytogenetics laboratory to enroll a patient on CALGB 8461. The Alliance Approved Institutional Cytogeneticists list is posted on the Alliance for Clinical Trials in Oncology website.

The purpose of this study is to determine if peripheral blood cells collected following AMD3100 mobilization can be used safely for hematopoietic cell transplantation into HLA-matched recipients.

Defects in the apoptotic process can lead to the onset of cancer by allowing cells to grow unchecked when an oncogeneic signal is present. Obatoclax is designed to restore apoptosis through inhibition of the Bcl-2 family of proteins, thereby reinstating the natural process of cell death that is often inhibited in cancer cells. This is a multi-center, open-label, Phase II study of obatoclax administered in 2-week cycles to patients with previously-untreated Myelodysplastic Syndromes with anemia and/or thrombocytopenia. Treatment may be administered on an outpatient basis. No investigational or commercial agents or therapies other than those described herein may be administered with the intent to treat the patient's malignancy. Supportive care measures including those directed at controlling symptoms resulting from Myelodysplastic Syndromes are allowed

Many patients with hematological malignancies potentially curable by bone marrow transplantation are not considered for transplantation because an HLA identical family or unrelated donor is unavailable. For these patients the only curative option is a transplant from a partially matched family donor. Such transplants are feasible but are less successful than matched sibling donor transplants. The main problems with mismatched transplants are graft rejection, graft-vs-host disease, and regimen-related mortality. This restricts the use of mismatched transplants to patients less than 45 years at high risk of dying from the hematological malignancy. This protocol evaluates a new preparative regimen designed to ensure stem cell engraftment by increased immunosuppression, followed by a G-CSF mobilized T cell depleted, stem cell rich, peripheral blood progenitor cell (PBPC) transplant from a mismatched related donor in patients with high risk hematological malignancies. This phase I study evaluates engraftment and GVHD following T cell depleted, HLA-mismatched PBPC transplants. Stopping rules will be used to make modifications to the protocol in the event of graft failure. The end points of the study are graft take, acute and chronic GVHD, leukemic relapse, transplant-related mortality, death and leukemia-free survival. Patients will be followed up for 5 years. It is planned to treat up to 35 patients aged between 10 and 45 years.
