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).
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 traditional way of doing a donor transplant is to give high doses of chemotherapy and radiation before giving the stem cells. However, high doses of chemotherapy and radiation can have serious side-effects. The doctors think that the transplant will be safer and more likely to be successful with reduced doses of chemotherapy and radiation. The purpose of this study is to find out how good a combination of chemotherapy and radiation at reduced doses followed by a cord blood transplant are at treating cancer. The stem cells chosen for the transplant are from umbilical cord blood. Umbilical cord blood is collected from healthy newborn babies and frozen. One cord blood collection is called a "cord blood unit." On transplant day, the cord blood will be given through the catheter just like a blood transfusion. Transplants done this way have been successful. However, this type of transplant is fairly new. Therefore, it is important to study it so the doctors can better understand how it works. Most blood or bone marrow transplants using donor stem cells are done as part of a study. When patients are on a study we test new ways of treating them which we think may be better than the old ways. We collect information about the result of this treatment so we can understand how well the treatment works. This is so we can learn better ways to treat our patients.
The purpose of the study is to elucidate the causative molecular events responsible for the abnormal erythropoiesis in MDS.
This phase II trial is studying how well umbilical cord blood transplant from a donor works in treating patients with hematological cancer. Giving chemotherapy and total-body irradiation (TBI) before a donor umbilical cord blood transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from an unrelated donor, that do not exactly match the patient's blood, 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 (called graft-versus-host disease). Giving cyclosporine and mycophenolate mofetil before and after transplant may stop this from happening.
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 phase II trial studies how well giving an umbilical cord blood transplant together with cyclophosphamide, fludarabine, and total-body irradiation (TBI) works in treating patients with hematologic disease. Giving chemotherapy, such as cyclophosphamide and fludarabine, and TBI before a donor umbilical cord blood transplant helps stop the growth of cancer and abnormal cells and helps 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 transplant may stop this from happening.
Patients are being asked to participate in this study because they will be receiving a stem cell transplant as treatment for their disease. As part of the stem cell transplant, they will be given very strong doses of chemotherapy, which will kill off all their existing stem cells. Stem cells are created in the bone marrow. They grow into different types of blood cells that we need, including red blood cells, white blood cells, and platelets. We have identified a close relative of the patients whose stem cells are not a perfect match for the patient, but can be used. This type of transplant is called "allogeneic", meaning that the cells come from a donor. With this type of donor who is not a perfect match, there is typically an increased risk of developing graft-versus-host disease (GvHD) and a longer delay in the recovery of the immune system. GvHD is a serious and sometimes fatal side effect of stem cell transplant. GvHD occurs when the new donor cells recognize that the body tissues of the patient are different from those of the donor. In the laboratory, we have seen that cells made to carry a gene called iCasp9 can be killed when they encounter a specific drug called AP1903. To get the iCasp9 into the T cells, we insert it using a virus called a retrovirus that has been made for this study. The drug (AP1903) that will be used to "activate" the iCasp9 is an experimental drug that has been tested in a study in normal donors, with no bad side effects. We hope we can use this drug to kill the T cells. Other drugs that kill or damage T cells have helped GvHD in many studies. However we do not yet know whether AP1903 will kill T cells in humans, even though it has worked in our experimental studies on human cells in animals. Nor do we know whether killing the T cells will help the GvHD. Because of this uncertainty, patients who develop significant GvHD will also receive standard therapy for this complication, in addition to the experimental drug. We hope that having this safety switch in the T cells will let us give higher doses of T cells that will make the immune system recover faster. These specially treated "suicide gene" T cells are an investigational product not approved by the Food and Drug Administration.
One of two different doses of thymoglobulin will allow bone marrow engraftment with minimal Graft-versus-Host Disease and allow adequate immune response to allow the transplanted stem cells to replace the tumor cells.
Study Objectives The aim of the study is to evaluate the safety and efficacy of the combination of 5-Aza-Cytidine + Thalidomide on the course of hrMDS patients. Primary end point: • To evaluate the overall response rate (CR+PR) of the combination of 5-Aza-Cytidine + Thalidomide in hrMDS patients (INT-2 and High risk as defined by IPSS). Secondary end points: - To evaluate the safety of the combination of Thalidomide+5-Aza-Cytidine in high risk MDS patients. - Hematological improvement rate. - Cytogenetic response. - Progression free survival (PFS). - Quality of life assessment (FACT: MDS and peripheral neuropathy QOL Questionnaires). Study design: This is a multicenter, phase II, single arm study designed to evaluate the safety and efficacy of the combination of Thalidomide+5-Aza-Cytidine in high risk MDS patients (INT-2 and High risk defined by IPSS) who are older than 18 years of age. Potential study subjects will sign an informed consent prior to undergoing any study related procedure. Number of patients to be enrolled 50. Treatment plan: 5-aza-cytidine (75 mg m2/d) will be injected subcutaneously in 5-day cycle every 28 days, for a total of 12 cycles. Thalidomide will be given at the dose of 50 mg/d, from day 1 until for 6 months together with 5-aza-cytidine . Treatment period includes 5-aza-cytidine (75 mg m2/d) will be injected subcutaneously in 5-day cycle every 28 days. Total number of 12 cycles or until progression or toxicity. Cycle delay of maximum 2 weeks in case of hematological toxicity grade 3-4 at investigator discretion. Duration of the follow up period is 6 months. Duration of study The duration of the treatment period is approximately 12 months. This time is required to complete the treatment, and to determine the safety profile and the response rate. The duration of the Follow period will be approximately a half year. The occurrence of PD will determine the duration of progression-free survival of each patient.
