MT2021-08T Cell Receptor Alpha/Beta Depletion PBSC Transplantation for Heme Malignancies

This is a phase II, open-label, prospective study of T cell receptor alpha/beta depletion (TCR α/β TCD) peripheral blood stem cell (PBSC) transplantation for children and adults with hematological malignancies. This is a safety/feasibility study of the investigational procedure/product.

Haploidentical Hematopoietic Cell Transplantation for Children With Hematologic Malignancies and Myelodysplasia

This is a Phase I/II study designed to evaluate the kinetics of hematopoietic reconstitution and the incidence of acute chronic GVHD after partially matched related donor hematopoietic cell transplantation using an αβTCR/CD19+ cell depleted graft.

Umbilical Cord Blood Transplantation Using a Myeloablative Preparative Regimen for Hematological Diseases

This is a treatment guideline for an unrelated umbilical cord blood transplant (UCBT) using a myeloablative preparative regimen for the treatment of hematological diseases, including, but not limited to acute leukemias. The myeloablative preparative regimen will consist of cyclophosphamide (CY), fludarabine (FLU) and fractionated total body irradiation (TBI).

Haploidentical Allogeneic Peripheral Blood Transplantation: Examining Checkpoint Immune Regulators' Expression

The standard Johns Hopkins' regimen will be used in study subjects, with the use of donor peripheral blood stem cells, rather than marrow. Clinical outcomes will be defined while focusing efforts on immune reconstitution focusing on immune checkpoint regulators after a related haploidentical stem cell transplant.

Contribution of Anti-platelet Antibodies Identified With MAIPA Assay in the Demonstration of the Auto-immune Character of a Thrombocytopenia at Diagnosis

Immune thrombocytopenia (ITP) is an autoimmune disease but, paradoxically, and unlike other autoimmune diseases, antiplatelet antibodies are not used either for the diagnosis of the disease or for its prognosis. ITP is a diagnosis of exclusion retained after elimination of other pathologies leading to a thrombocytopenia. No major study has prospectively evaluated the diagnostic value of the presence of anti-platelet antibodies in the etiological investigation of a thrombocytopenia, nor the impact of platelet antibodies on the course of ITP. The gold standard analysis for the determination of platelet antibodies, is the "monoclonal antibody immobilization of platelet antigens" assay (MAIPA), either direct to detect autoantibodies attached to platelets, or indirect to detect circulating antiplatelet antibodies. Therefore, this work aims to study the contribution of the presence of anti-platelet antibodies detected in MAIPA to determine the autoimmune nature of a thrombocytopenia at diagnosis.

Trial Evaluating MGTA-456 in Patients With High-Risk Malignancy

This is an single arm, open label, interventional phase II trial evaluating the efficacy of umbilical cord blood (UCB) hematopoietic stem and progenitor cells (HSPC) expanded in culture with stimulatory cytokines (SCF, Flt-3L, IL-6 and thromopoietin) on lympho-hematopoietic recovery. Patients will receive a uniform myeloablative conditioning and post-transplant immunoprophylaxis.

Dose-Expansion Study of Low Dose Post-Transplant Cyclophosphamide/Tacrolimus/Ruxolitinib for Graft-versus-Host Disease (GVHD) Prophylaxis in Myeloablative Allogeneic Peripheral Blood Stem Cell Transplantation

This is an open label, non-randomized, multicenter, pilot, dose expansion study of low dose post-transplant cyclophosphamide (25 mg/kg on Days +3 and +4)/tacrolimus/ruxolitinib in the setting of myeloablative conditioning (MAC) allogeneic peripheral blood stem cell transplantation (PBSCT).

Allogeneic Stem Cell Transplant With Alpha/Beta T AND B Cell Depletion for Hematologic Malignancies

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.

Myeloablative Allo HSCT With Related or Unrelated Donor for Heme Disorders

This is a Phase II study of allogeneic hematopoietic stem cell transplant (HCT) using a myeloablative preparative regimen (of either total body irradiation (TBI); or, fludarabine/busulfan for patients unable to receive further radiation). followed by a post-transplant graft-versus-host disease (GVHD) prophylaxis regimen of post-transplant cyclophosphamide (PTCy), tacrolimus (Tac), and mycophenolate mofetil (MMF).

ATG Plus PTCy vs ATG for CGVHD Prophylaxis

A Randomized Pilot Trial to test the feasibility of comparing anti-thymocyte globulin plus post transplant cyclophosphamide with anti-thymocyte globulin alone to prevent chronic graft versus host disease.

MCW Alpha/Beta T-Cell and B-Cell Depletion With Targeted ATG Dosing

This is a single arm pilot study for patients with hematologic malignancies receiving unrelated or haploidentical related mobilized peripheral stem cells (PSCs) using the CliniMACS system for alpha/beta T cell depletion plus CD19+ B cell depletion with individualized ALC-based dosing of ATG to study impact on engraftment, GVHD, and disease free survival

Collecting and Storing Blood, Bone Marrow, and Other Samples From Patients With Acute Leukemia, Chronic Leukemia, or Myelodysplastic Syndromes

As one of the nation's largest cooperative cancer treatment groups, the Alliance for Clinical Trials in Oncology (Alliance) is in a unique position to organize a Leukemia Tissue Bank. The member institutions diagnose hundreds of patients with leukemia or myelodysplastic syndrome each year, and uniformly treat these patients with chemotherapy regimens. The Alliance offers centralized data management for the clinical history, the classification of the leukemia and myelodysplastic syndrome, cytogenetics, flow cytometric analysis, treatment and follow-up. The highly skilled health care providers at each member institution are familiar with obtaining informed consent, completing data questionnaires and shipping specimens. There currently exists a central processing facility where samples are prepared for a variety of cellular and molecular studies. Hence, the patient resources, the health care providers, and a processing facility for a Leukemia Tissue Bank are all in place. What is needed, however, and is addressed in the current protocol, is a formal mechanism to procure bone marrow, blood and normal tissue from patients with hematologic malignancies who are to be enrolled on Alliance (Cancer and Leukemia Group B \[CALGB\]) treatment studies.

Randomised Study of Oral Azacitidine vs Placebo Maintenance in AML or MDS Patients After Allo-SCT

This study will evaluate a new maintenance therapy with the aim of improving the outcome of patients with acute myeloid leukaemia (AML) and myelodysplasia (MDS) after stem cell transplantation.
