Filter by:The purpose of this study is to evaluate the response rate of decitabine in previously treated and untreated Taiwanese participants with Myelodysplastic Syndrome (MDS - a disease associated with decreased production of blood cells, blood cells are produced but do not mature normally).
Angiogenesis increases in higher risk MDS patients and those with proliferative CMML. Angiogenesis is associated with increased risk of leukemic transformation and poorer prognoses. Low dose chemotherapy may have anti-angiogenic properties by targetting the genetically stable endothelial cells. Lenalidomide has been recently shown to be highly effective as monotherapy in low/low-intermediate risk MDS, particularly in the subgroup harboring a 5q- deletion. Lenalidomide has not been well studied in higher risk MDS although there are some reports of lenalidomide's efficacy in RAEB-T and AML. One potential mode of action of lenalidomide is inhibition of angiogenesis. The investigators hypothesize that by combining lenalidomide with low dose melphalan in higher risk MDS the investigators will more effectively block angiogenesis and achieve responses or hematologic improvement in MDS.
This is an open label, dose escalation study with 3 arms (Arms A, B, and C). Arm A will assess the safety and tolerability of escalating doses of SB939 in cohorts of patients with advanced solid tumors. Arm B will assess the safety and tolerability of escalating doses in cohorts of patients with advanced hematologic malignancies. Arm C will assess the safety and tolerability of SB939 in combination with standard azacitidine therapy.
The National Marrow Donor Program (NMDP) has established a system for registering, matching, and tracking unrelated donor cord blood units (CBUs) and transplant outcomes. Study subjects are donors who enroll through collaborating cord blood banks. This study creates uniform collection, screening, testing and storage requirements for cord blood units. The purpose of standardization is to improve efficiency in the selection of cord blood units for transplantation.
RATIONALE: Giving low doses of chemotherapy and antithymocyte globulin before a donor stem cell transplant helps stop the growth of cancer and abnormal cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer and abnormal cells (graft-versus-tumor effect). PURPOSE: This phase II trial is studying how well a donor stem cell transplant works after busulfan, fludarabine, and antithymocyte globulin in treating patients with hematologic cancer or myelodysplastic syndrome.

PURPOSE: This phase II trial is studying how well a donor stem cell transplant works after busulfan, fludarabine, methylprednisolone, and antithymocyte globulin in treating patients with bone marrow failure syndrome.
The purpose of the study is to elucidate the causative molecular events responsible for the abnormal erythropoiesis in MDS.
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).
This study consists of two phases: the first portion of the study is a Phase 1 dose escalation study to determine the maximum tolerated dose and the dose limiting toxicities of SB1518 when given as a single agent orally once daily in subjects with advanced myeloid malignancies; the second portion of the study is a Phase 2 study to define the efficacy and safety profile of single-agent SB1518 at the recommended dose in subjects with chronic idiopathic myelofibrosis (CIMF).
RATIONALE: American ginseng may reduce fatigue in patients with cancer. It is not yet known whether American ginseng is more effective than a placebo in treating cancer-related fatigue. PURPOSE: This randomized phase III trial is studying American ginseng to see how well it works in treating patients with fatigue caused by cancer.
