Active clinical trials for "Myelodysplastic Syndromes"

This is a single arm pilot study for patients using α/β T cell-depleted peripheral Stem Cell Transplantation (PSCT) in with alternative donor sources with hematologic malignancies receiving alternative donor (unrelated or partially matched related) mobilized peripheral stem cells (PSCs) using the CliniMACS system for T cell depletion plus CD19+ B cell depletion to determine efficacy as determined by engraftment and graft versus host disease (GVHD), and one year leukemia free survival.

This phase I/II trial studies the side effects and best dose of ONC201 and to see how well it works in treating patients with acute leukemia or high-risk myelodysplastic syndrome that has returned after a period of improvement (relapsed) or does not respond to treatment (refractory). ONC201 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

The purpose of this study is to determine the overall safety of adoptive immunotherapy when given after chemotherapy for AML/MDS. Adoptive immunotherapy means using an infusion of cells from a donor to help fight cancer. The donor cells will be either from the umbilical cord blood (UCB) of a newborn baby or they will be cells collected from a relative (haplo-identical cells). The 2 cohorts that were discussed - adoptive immunotherapy with either UCB or haplo-identical stem cells - will be analyzed separately. Preliminary data from other centers has suggested that adoptive immunotherapy with cells from a relative is an effective approach that may improve remission rates and survival in AML and MDS, because they exert anti-cancer effects of their own (so called graft vs leukemia effects) and possibly because they hasten recovery of cell counts from chemotherapy. The Investigators are interested in confirming these data, but also in testing umbilical cord blood cells for the same purpose. Preliminary data indicate that umbilical cord blood cells may have more powerful graft vs leukemia effects and cause fewer side-effects.

This is a prospective phase II clinical study planned to be conducted at the Medical College of Wisconsin (MCW). After meeting the study criteria and enrollment, patients will be treated with a cladribine based salvage regimen and followed at periodic intervals to determine the primary and secondary objectives.

This phase Ib trial studies the side effects and best dose of nivolumab and ipilimumab after donor stem cell transplant in treating patients with high risk acute myeloid leukemia or myelodysplastic syndrome that does not respond to treatment or has come back. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

This phase I/II trial studies how well quizartinib, decitabine, and venetoclax work in treating participants with acute myeloid leukemia or high risk myelodysplastic syndrome that is untreated or has come back (relapsed). Quizartinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as decitabine and venetoclax, work 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. Giving quizartinib and decitabine may work better at treating acute myeloid leukemia and myelodysplastic syndrome.

This study will evaluate the safety, tolerability, and efficacy of engineered donor grafts ("OrcaGraft"/"Orca-Q") in participants undergoing myeloablative allogeneic hematopoietic cell transplant transplantation for hematologic malignancies.

Allogeneic hematopoietic stem cell transplantation is a life-saving procedure in patients with blood cancers. Cord blood (CB) represents an alternative source of stem cells, which is associated with a lower risk of relapse, especially in the presence of minimal residual disease in the setting of acute leukemia and myelodysplasia. Furthermore, CB has the added advantage of being associated with a low risk of chronic graft versus host disease (GVHD). Unfortunately, CB transplants are hampered by a higher risk of transplant related mortality (TRM) when compared to bone marrow/peripheral blood transplants because of the limited cell dose of CB. In the previous UM171 trial (NCT02668315), the CB expansion protocol using the ECT-001-CB technology (UM171 molecule) has proven to be technically feasible and safe. UM171 expanded CB was associated with a median neutrophil recovery at day (D)+18 post transplant. Amongst 22 patients who received a single UM171 CB transplant with a median follow-up of 18 months, risk of TRM (5%) and grade 3-4 acute GVHD (10%) were low. There was no moderate-severe chronic GVHD. Thus, overall and progression free survival at 12 months were impressive at 90% and 74%, respectively. The UM171 expansion protocol allowed access to smaller, better HLA matched CBs as >80% of patients received a 6-7/8 HLA matched CB. Interestingly there were 5 patients who had already failed an allogeneic transplant and 5 patients with refractory/relapsed acute leukemia/aggressive lymphoma. Despite this high risk population, progression was 20% at 12 months. Hence, in this new trial, investigators are targeting patients with high and very high-risk acute leukemia/myelodysplasia to test the antileukemia effect of this new graft, a UM171 expanded CB.

This study aims at evaluating the safety of an approach based on HLA-mismatched Microtransplantation without immunosuppressive treatment in patients With myeloid hemopathies who are ineligible to conventional allograft

A significant number of patients with hematologic malignancies need a hematopoietic stem cell transplant (HSCT) to be cured. Only about 50% of these patients have a fully matched donor, the remaining patients will require an HSCT from a mismatched related or unrelated donor. Almost 60% of these mismatched donor HSCTs will result in graft-versus-host disease (GvHD), which can cause significant morbidity and increased non-relapse mortality. GvHD is caused by the donor effector T cells present in the HSC graft that recognize and react against the mismatched patient's tissues. Researchers and physicians at Lucile Packard Children's Hospital, Stanford are working to prevent GvHD after HSCT with a new clinical trial. The objective of this clinical program is to develop a cell therapy to prevent GvHD and induce graft tolerance in patients receiving mismatched unmanipulated donor HSCT. The cell therapy consists of a cell preparation from the same donor of the HSCT (T-allo10) containing T regulatory type 1 (Tr1) cells able to suppress allogenic (host-specific) responses, thus decreasing the incidence of GvHD. This is the first trial of its kind in pediatric patients and is only available at Lucile Packard Children's Hospital, Stanford. The purpose of this phase 1 study is to determine the safety and tolerability of a cell therapy, T-allo10, to prevent GvHD in patients receiving mismatched related or mismatched unrelated unmanipulated donor HSCT for hematologic malignancies.
