Active clinical trials for "Myelodysplastic Syndromes"

This is a phase II, single-center study to evaluate the efficacy of a novel cytoreductive regimen followed by CD34+E- selected T cell depleted allogeneic stem cell (or soybean agglutinated and E-rosetted BM) transplant as treatment for patients with acute and chronic leukemias, lymphoma and myelodysplstic syndrome/PNH. The impact of the change in conditioning regimen and use of CD34-selected T cell depleted PBSCs on transplanted related morbidity and mortality and disease free survival will be assessed.

This study proposes using bortezomib in cohorts of 3-6 patients at the doses of 0.7, 1, and 1.3 mg/m2 on days 1, 4, 8, and 11 to determine the MTD in combination with lenalidomide 10 mg a day, for 21 days of a 28 day treatment cycle for patients with myelodysplastic syndrome.

Allogeneic transplantation is used to treat many malignant and non-malignant diseases, though the potential toxicities of the procedure remain high. We and others have shown that a less toxic preparative regimen allows reliable allogeneic engraftment for allogeneic transplantation. The primary purpose of this treatment trial is to follow patients undergoing allogeneic transplantation for long term outcomes. The regimen used has been tested in our prior phase I / II trial which has completed accrual. The issues of engraftment and rate of graft versus host disease have been answered and our success has led to this regimen being a standard approach for less toxic allogeneic therapy.

This is an open label, multicenter Phase 1 dose escalation study evaluating five doses of ezatiostat in combination with lenalidomide in patients with non-del(5q) low to intermediate 1 risk MDS. The HI-E, HI-N, HI-P rates [by International Working Group (IWG) 2006 criteria] and safety of each treatment group will be evaluated to select the optimal dose of ezatiostat in combination with lenalidomide for future studies.

The purpose of this study is to examine the feasibility and efficacy of using the demethylating agent 5-Azacytidine prior to allogeneic stem cell transplantation in patients with high risk myelodysplastic syndrome (MDS).

Objectives: To evaluate disease free survival after Campath 1H-based in vivo T-cell depletion and non-myelo-ablative ablative stem cell transplantation in patients with hematologic malignancies. To evaluate the incidence and severity of acute and chronic GVHD after Campath 1H-based in vivo T-cell depletion, in patients with hematologic malignancies undergoing non-myelo-ablative stem cell transplantation. To evaluate engraftment and chimerism after Campath 1H-based in vivo T-cell depletion and non-myelo-ablative ablative stem cell transplantation in patients with hematologic malignancies.

RATIONALE: Giving chemotherapy and total marrow irradiation before a donor umbilical cord blood or hematopoietic stem cell transplant helps stop the growth of 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. 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 total marrow irradiation when given together with combination chemotherapy and umbilical cord blood hematopoietic stem cell transplant in treating patients with acute leukemia, acute myeloid leukemia or multiple myeloma that did not respond to previous therapy.

The primary objective of this study is to evaluate the efficacy and safety of ON 01910.Na Concentrate when it is administered as an intravenous continuous infusion (IVCI) over 72 hours once every 2 weeks in a broad population of MDS patients. Rationale for this study is based on the activity observed in another study with ON 01910.Na in patients with refractory anemia with excess blasts (RAEB) 1 and 2 MDS. This study will examine ON 01910.Na in a broader population of MDS and AML patients. This phase I/II study will establish the Maximum Tolerated Dose (MTD) starting with a dose of 800 mg/m2 per day administered over 24 hours for 2 consecutive days as a continuous intravenous infusion, once a week for 3 weeks of a 4-week cycle and examine the efficacy and safety profile at the MTD.

This phase I trial is studying the side effects and best dose of 7-hydroxystaurosporine when given together with perifosine in treating patients with relapsed or refractory acute leukemia, chronic myelogenous leukemia, or myelodysplastic syndromes. 7-Hydroxystaurosporine may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as perifosine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving 7-hydroxystaurosporine together with perifosine may kill more cancer cells.

RATIONALE: Drugs used in chemotherapy, such as fludarabine and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill cancer cells. An umbilical cord blood transplant may be able to replace blood-forming cells that were destroyed by chemotherapy and radiation therapy. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving sirolimus and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase II trial is studying how well giving fludarabine and cyclophosphamide together with total-body irradiation followed by an umbilical cord blood transplant, sirolimus, and mycophenolate mofetil works in treating patients with hematologic cancer.
