Filter by:The purpose of this study is to determine whether cyclophosphamide post bone marrow transplant increases the rate of patients alive, in remission and without immunosuppression, one year after transplant, when compared with the combination of methotrexate and calcineurin inhibitor
Azacytidine (AZA) is the current standard of care for frontline patient treated with high-risk MDS and is clinically active in all type of MDS, however, 50% of the patients will never respond. Vorinostat is an orally available HDAC inhibitor with clinical activity in MDS and proven in vitro synergy with AZA. Patient treated upfront with a combination of this agents have shown more responses based on phase I/II data. In the present study, we will use the combination of these two drugs to try to create a synergetic effect and generate a response for patients who experienced treatment failure after AZA. All eligible patients will be treated with Azacitidine and oral vorinostat for 6 cycles of 28 days. Study Design
The purpose of this study is to help determine if palifermin and leuprolide acetate can help the immune system recover faster following a stem cell transplant. Blood stem cells are very young blood cells that grow in the body to become red or white blood cells or platelets. The transplant uses stem cells in the blood from another person. The donor can be a family member or a volunteer donor. This is called an allogeneic stem cell transplant. The investigators want to see if palifermin and leuprolide acetate can help the immune system recover faster after an allogenic transplant because experiments have shown they may be able to do this.
The purpose of this study is compare the efficacy of haplo-cord transplant (investigational arm) with that of a more commonly used procedure in which only the cells contained in one or two umbilical cords are infused (standard arm). We hypothesize that reduced intensity conditioning and haplo-cord transplant results in fast engraftment of neutrophils and platelets, low incidences of acute and chronic graft versus host disease, low frequency of delayed opportunistic infections, reduced transfusion requirements, shortened length of hospital stay and promising long term outcomes. We also hypothesize that umbilical cord blood selection can prioritize matching and better matched donors can be identified rapidly for most subjects.
Reviewing Spanish record of myelodysplastic syndromes (RESMD) data base in the group of patients with MDS. The information will be collected retrospectively from diagnosis of MDS, until the date of December 31, 2011.
It has been shown in preclinical experiments with bone marrow from patients with myelodysplastic syndrome that APG101 rescues erythrocytes from premature cell death. This is expected to translate in an improved erythropoiesis and ameliorated anemia in MDS patients. APG101 might, therefore, be a valuable addition to current treatments of low- or intermediate MDS patients suffering from anaemia. Transfusion-dependent patients with low or intermediate risk MDS according to WHO Prognostic Scoring Scale (WPSS) can be included in this study. Treatment consists of 100mg APG101 intravenous as a weekly treatment over 12 weeks + 6 months follow up phase. Primary objective of the trial is safety and tolerability of APG101; secondary objectives are - Hematologic, cytologic and cytogenetic response rate using modified International Working Group (IWG) response criteria - Incidence and time to leukemic progression at 37 weeks - OS (Overall survival) at 37 weeks
Patients with some forms of acute myeloid leukemia (AML) and multiple myeloma (MM) are not cured with conventional therapy and new approaches are needed. For the last 15 years we have investigated the potential of using a patient's own T cells (a type of white blood cell [WBC]) to eradicate the tumor. We have demonstrated the feasibility of this approach in cell culture and animal models of AML and MM. Over the last 5 years we have been preparing to treat patients as part of a Phase I (first in human) clinical trial. The trial treatment involves collecting the patient's own WBCs from the blood by a standard well established and safe process called apheresis. The cells are then cultured in a specialized laboratory (under Good Manufacturing Practice conditions, similar to standards under which pharmaceuticals are produced) over 12 days to convert the cells to specialized tumor-attacking T cells. Early in that culture process the cells are exposed to a virus (that is modified so that it cannot infect or replicate outside the special culture conditions) that contains a special gene. Via the virus, this gene inserts into the patient's T cells in culture and gets incorporated into the T cell's genetic machinery. As the T cells replicate, the new gene produces a protein receptor that becomes part of the patient's T cells. This protein receptor on the T cells has the capacity to specifically recognize and bind to a protein on the leukemia or myeloma cells called the "Lewis Y" antigen. After the modified T cells are infused into the patient, they home into the bone marrow (this tracking is monitored by special radiological techniques) where the new protein receptor on the T cell surface can recognize and bind to the cancer cells (which express Lewis Y). Once bound onto the cancer cells, the T cells get activated and subsequently replicate and kill the cancer cells. The novelty of this approach is that the T-cells will only kill cells that have the Lewis Y on their surface - the cancer cells. Moreover, because there are few normal cells in a person's body that carry Lewis Y, this treatment is likely to only have minor side effects. This gene therapy trial is unique and although the primary purpose is to test the safety of this approach, patients will be monitored closely for anti-tumor responses. As the trial progresses, the dose of T cells infused will increase, in the hope that this will result in a better and stronger immune response to the leukemia or myeloma.
Acute myeloid leukemia (AML) is a rapidly fatal malignancy of the bone marrow. It can be treated with chemotherapy alone, in some cases, but in the majority of cases, the only treatment that can cure the disease is an allogeneic stem cell transplant, with a cure rate of 30-40%. In another subset, the disease is less responsive to chemotherapy and in these aggressive forms, its cure rate is no better than 20% beyond 2 years, and is usually rapidly fatal within 6 months. Therefore, for this most aggressive form of the disease, modifications to the transplant protocol are required in order to try to improve on these poor results. There are a number of areas within the transplant protocol on which modifications can be made in order to achieve these goals. These include: higher doses of chemotherapy and or radiation; alterations of the new bone marrow graft; and alterations of the immune suppression, enhancing the graft vs. leukemia effect. By focusing on one or more of these components, one might be able to enhance the anti-leukemic aspect of the treatment resulting in a more successful outcome. One aspect the investigators, in Ottawa, have focused on is the initial intensive conditioning regimen, specifically the radiation component. It is the investigators belief that in the most resistant disease it is important to use the highest tolerable anti-leukemic treatment upfront, specifically, enhancing the radiation component of the initial conditioning regimen. Previous studies have suggested that higher doses of radiation might be more effective at eliminating the disease, however, toxicity and logistics of delivering the radiation have limited its use. Technical advances in the delivery of radiation have now permitted the safer use of high doses of radiation. Through modifications to the transplant procedure, the investigators believe that they can deliver higher doses of radiation safely and this will translate into improved outcomes in this high-risk subgroup of patients with AML. Study Objectives The goal of this study is to determine if a total dose of 18Gy ED-TBI followed by an alloHSCT for patients with refractory AML will result in an improved progression-free survival.
To determine the impact of maintenance therapy in patients with MDS/AML in remission.
The purpose of this study is to investigate tolerability when SyB L-1101 is administered intravenously in patients with recurrent/relapsed or refractory myelodysplastic syndrome, to determine the dose-limiting toxicity and maximum tolerated dose, and to estimate the recommended dose for phase II studies. Pharmacokinetics and antitumor effects will also be investigated.
