Active clinical trials for "Myelodysplastic Syndromes"

The reconstitution of a functioning immune system after allogeneic stem cell transplantation takes months to years. Particularly memory B-lymphocytes reconstitute poorly with the current conditioning regimes. During the period of intense immune suppression the patients are extremely susceptible to bacterial, fungal and, most importantly, viral infections.The adoptive transfer of B-lymphocytes from the stem-cell donor might significantly enhance humoral immunity for the patient. Aim of the study is to evaluate a new cellular therapy with B-lymphocytes regarding safety. A booster vaccination after B-lymphocyte transfer will evaluate the functionality of the transferred B-lymphocytes in the patient.

This is a Phase II study to evaluate the efficacy of second-line lenalidomide monotherapy for myelodysplastic syndrome (MDS) patients who failed to hypomethylating agents.

The purpose of this study is determine whether combination Q10 , L-carnitine and multivitamin and mineral complex is effective in treatment of patients with low and intermidiate1-2 risk Myelodysplastic syndrome

The purpose of this study is to evaluate of the safety and efficacy of decitabine treatment of Myelodysplastic Syndrome.

The purpose of this study is to evaluate of the clinical efficacy and safety of DLAAG protocol in the treatment of acute myeloid leukemia (AML) and myelodysplastic syndrome with blast excess

The objective of the phase I part of the trial is the determination of the maximum tolerated dose (MTD) of TCP (Tranylcypromine) in combination with fixed-dose ATRA (all-trans-retinoic acid) and with fixed-dose AraC (Cytarabine) and to derive the recommended phase II dose (RP2D) in patients with non-APL AML or MDS for whom no standard treatment is available or who failed azanucleoside treatment. The objective of the phase II part of the trial is a first evaluation of the efficacy of TCP at the RP2D in combination with fixed-dose ATRA and with fixed-dose AraC as basis for further investigations of TCP

This research study is assessing the efficacy of MBG-453, a humanized monoclonal antibody, in treating myelodysplastic syndromes (MDS). The name of the study drug involved in this study is MBG453.

Brief Scientific Rationale: Decitabine has been shown to be effective for treatment of MDS and associated with very limited extramedullary toxicity at the lower doses. Furthermore, the hypomethylating effects of decitabine require an extended period of therapy and are likely to be more beneficial in the setting of a minimal residual disease after transplantation. The drug might exert a cytoreductive effect on the MDS clone, but ex vivo expansion strategy using decitabine and HDAC inhibitor provides a potential to expand the number of hematopoietic stem cells. There are lots of evidence which showed the the drug have immunostimulatory effects and can be used to enhance graft-versus leukemia effects. And also, some investigator suggested that decitabine could induce FOXP3 expression, promoting the conversion of naïve T cells to Tregs which are known to suppress GVHD while maintaining GVL effect in allo-SCT setting. As such, decitabine is an ideal agent to be investigated in the post-transplant setting. The investigators hypothesized that post-transplant maintenance therapy with decitabine may reduce relapse rate, which may maximize the beneficial effects from reduced TRM of ATG-containing FB4 or FB2 conditioning regimen in higher-risk MDS or AML evolving from MDS patients.

Transfusional dependence has been associated closely and independently with low survival in patients with myelodysplastic syndrome (MDS), especially in patients at low risk according to IPSS. Treatment of patients with hydralazine + valproic acid as an alternative to treatment with 5-azacytidine has lower cost and possibly as effective with fewer side effects. The objective of this phase II study is to determine the effectiveness of combination therapy with hydralazine + Ac. Valproic compared with best supportive care. The investigators will select 42 patients per group, and after 14 weeks of treatment the investigators will study in both groups the hematological response (transfusion-dependent, hemoglobin, cytogenetics and morphology) and treatment safety (adverse reactions and vital signs) to 1 year after starting treatment. The concentration of hemoglobin, the number of transfusions, platelets, neutrophils and other continuous variables in both groups will be compared by Student t or Mann-Whitney, as appropriate. For comparison of cytogenetic and morphological response and other categorical variables between groups Chi square will be used. And within each group the investigators will compare each of these variables before and after treatment by t-test for paired data or Wilcoxon test.

RATIONALE: Studying samples of blood in the laboratory from patients with cancer may help doctors learn more about nausea and vomiting caused by cancer treatment. PURPOSE: This laboratory study is looking at blood samples from patients with cancer who were treated on a clinical trial to control nausea and vomiting during donor stem cell transplant.
