数据说明

Conditions: Myelodysplastic Syndrome, Acute Myeloid Leukemia, Chronic Myelomonocytic Leukemia. This trial can be divided into four phases: 1) Pre-Transplant; 2) Allogeneic Transplant; 3) Vaccination; and 4) Post-Vaccination Follow-Up. Phase 1: Pre-Transplant After signing the consent form participants will undergo some screening tests to find out if they can be in this research study. These tests include a medical history, physical examination, performance status, bone marrow aspirate and biopsy, blood tests, tuberculosis skin test, HLA antibody test, pregnancy test, urine test, ECHO, MUGA or RVG to measure heart function, chest x-ray, pulmonary function tests and dental consult. If these tests show that participants are eligible to participate in the research study, they will be enrolled on the trial and randomized to receive either the GVAX vaccine or the placebo vaccine after their transplant. After enrolling in the study participants will undergo additional research procedures including a blood draw and leukemia cell collection. Phase 2: Allogeneic Transplant The transplant phase of the study will begin when participants are admitted to the hospital to receive the chemotherapy and stem cell transplant. In the week before participants receive the stem cells, they will be treated with chemotherapy. The combination of chemotherapy given before the donor cells are infused is called the conditioning regimen. The chemotherapy conditioning is given to suppress the immune system so that the donor blood stem cells will not be rejected after transplantation. The chemotherapy may also reduce the number of MDS/CMML/AML cancer cells in participants’ body. In this study the condition regimen will include 2 chemotherapy drugs: busulfan (twice a day or four times a day for 4 days) and fludarabine (once daily for 4 days). Depending on participants’ age and other clinical factors, the transplant doctor will decide whether they receive a higher or lower dose of busulfan. Between 1-2 days after participants finish the chemotherapy, they will receive the blood stem cell or ma
