BACKGROUND Recent investigations have shown that mutations in epigenetic regulators are common, both in the apparently normal hematopoiesis of the elderly and in patients (pts) with myeloid cancers. It was long anticipated that DNA methylation was a permanent silencing mark, but with the discovery
The active metabolite of SGI-110 (2'-deoxy-5-azacytidylyl-(3'→5')-2'-deoxyguanosine sodium salt), a dinucleotide, is decitabine, an FDA-approved agent for the treatment of myelodysplastic syndromes. SGI-110 is resistant to modification by cytidine deaminase, a common pathway of decitabine metabolism
Describe succinctly and clearly the past findings which justify the plan for this project. A summary of the relevant literature in the area of interest and reports of previous studies should be included.
For majority of lymphoma patients who relapse after complete response or who are primary
Rationale: Graft-versus-host disease (GVHD) remains a major cause of morbidity and mortality after allogeneic HSCT. The combination of a calcineurin inhibitor and methotrexate has been the standard GVHD prophylactic regimen for the past 20 years. However, the incidence of acute GVHD remains high,
In the United States, the incidence of acute myeloid leukemia (AML) is approximately 3.5 cases per 100,000 persons per year. Approximately 13,000 people were diagnosed with AML in 2009 and 9,000 died of the disease, making AML the 6th leading cause of cancer death. Over the past three decades, AML
This is a three-part phase 1 study in which nineteen to one hundred two patients with Low, Intermediate-1, Intermediate-2, or High risk MDS will receive oral doses of ON 01910.Na Concentrate as escalating single or multiple doses (70mg to 700 mg bid) up to 14 days of a 21-day cycle.
Part I:
The Study Drugs:
Azacitidine is designed to block certain proteins that stop the function of tumor-fighting genes. By blocking the "bad" proteins, the tumor-fighting genes may be able to work better.
Lenalidomide is designed to change the immune system. It may also interfere with the development of
The Study Drugs:
Azacitidine is designed to block certain genes in cancer cells whose job is to stop the function of the tumor-fighting genes. By blocking the "bad" genes, the tumor-fighting genes may be able to work better.
Vorinostat is designed to cause chemical changes in different groups of
The trial proposed is a single arm, phase II treatment protocol designed to examine the engraftment, toxicity, graft-versus-host disease and ultimate disease-free survival following transplants derived from (1) HLA-matched siblings or related donors, (2) HLA-compatible unrelated donors or (3) HLA
In murine and human xenograft tumor models, administration of PS-341 weekly was associated with significant antitumor activity. In primate studies using a schedule of twice weekly for six weeks, the highest PS-341 dose not associated with severe irreversible toxicity was 0.067 mg/kg/dose or 0.80
Bone marrow stem cell transplant studies carried out by the NHLBI BMT Unit have focused on approaches to optimize the stem cell and lymphocyte dose in order to improve transplant survival and increase the graft-vs.-leukemia effect. The aim is to create the transplant conditions that permit rapid
