Filter by:This phase I trial studies how well the combination of magrolimab works with azacitidine after a donor stem cell transplant (allogeneic hematopoietic cell transplantation) in treating patients with high-risk acute myeloid leukemia or myelodysplastic syndrome. Magrolimab is a type of protein called an antibody. It is designed to target and block a protein called CD47. CD47 is present on cancer cells and is used by cancer cells to protect themselves from the body's immune system. Blocking CD47 with magrolimab may enable the body's immune system to find and destroy the cancer cells. Azacitidine is a chemotherapy drug that may prevent the return of acute myeloid leukemia or myelodysplastic syndrome by working in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Combining magrolimab and azacitidine may kill more cancer cells after allogeneic hematopoietic cell transplantation in patients with high-risk acute myeloid leukemia or myelodysplastic syndromes.
This study will evaluate whether processing blood stem cell transplants using an investigational device (the CliniMACS system) results in fewer complications for patients who undergo transplant to treat a blood malignancy (cancer) or blood disorder. The CliniMACS system will be used to remove immune T-cells from the transplant donor's blood. Immune T-cells contribute to graft versus host disease (GVHD) - a serious complication that can happen after transplant. GVHD occurs when a patient's immune system attacks the donor's cells. The study aims to reduce the number of the donor immune T-cells thereby preventing or reducing the severity of GVHD.
This is a 2-part, phase 1/2, open-label, multicenter study designed to evaluate the safety and efficacy of fadraciclib (formerly CYC065) administered orally BID. This study consists of Phase 1 and Phase 2 components in subjects with Leukemia or Myelodysplastic syndrome (MDS) who have progressed despite having standard therapy or for which no standard therapy exists.
The study is to evaluate safety and efficacy of IBI188 in combination with azacitidine (AZA) as a first-line treatment in subjects with newly diagnosed higher risk myelodysplastic syndrome
The protocol is a phase I open label study evaluating the safety and feasibility of peri-transplant infusion of freshly expanded interferon gamma primed MSCs in adult and pediatric patients undergoing HCT for acute leukemia and myelodysplastic syndrome (MDS).
This phase I/II trial studies the side effects and best dose of a radioactive agent linked to an antibody (211At-BC8-B10) followed by donor stem cell transplant in treating patients with high-risk acute leukemia or myelodysplastic syndrome that has come back (recurrent) or isn't responding to treatment (refractory). 211At-BC8-B10 is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Giving chemotherapy and total body irradiation before a stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer 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 attack the body's normal cells, called graft versus host disease. Giving cyclophosphamide, mycophenolate mofetil, and tacrolimus after a transplant may stop this from happening.
This phase I trial studies the side effects and best dose of CD4+ and CD8+ HA-1 T cell receptor (TCR) (HA-1 T TCR) T cells in treating patients with acute leukemia that persists, has come back (recurrent) or does not respond to treatment (refractory) following donor stem cell transplant. T cell receptor is a special protein on T cells that helps them recognize proteins on other cells including leukemia. HA-1 is a protein that is present on the surface of some peoples' blood cells, including leukemia. HA-1 T cell immunotherapy enables genes to be added to the donor cells to make them recognize HA-1 markers on leukemia cells.
The purposes of the study is to determine the safety and efficacy of human umbilical cord mesenchymal stem cells (hUC-MSC) in treating Myelodysplastic Syndrome patients.
This phase I/II trial studies the side effects and best dose of 211^astatine(At)-BC8-B10 before donor stem cell transplant in treating patients with high-risk acute myeloid leukemia, acute lymphoblastic leukemia, myelodysplastic syndrome, or mixed-phenotype acute leukemia. Radioactive substances, such as astatine-211, linked to monoclonal antibodies, such as BC8, can bind to cancer cells and give off radiation which may help kill cancer cells and have less of an effect on healthy cells before donor stem cell transplant.
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.
