Filter by:Participants in the expanded access program are adults with higher-risk myelodysplastic syndromes who have no other treatment options available. The main aim of this program is to allow participants to have access to pevonedistat before FDA approval. This program will take place in the United States.
This is an expanded access program (EAP) for eligible participants designed to provide access to ACE-011.
Allogeneic hematopoietic stem cell transplantation (HSCT) is an established form of treatment for hematological abnormalities. Poor graft function, occurs when there poor donor engraftment. A second infusion of unselected donor hematopoietic stem cells (HSC) can result in improvement, but can potentially increase the incidence of graft versus host disease. Cluster of differentiation 34+ (CD34+) selected stem cells depleted of T-cells is an attractive alternative for treatment of poor graft function as it may be associated with less Graft versus Host Disease (GVHD) and enhanced count recovery. The investigators are using the Miltenyi CliniMACS device and CD34 cell selection reagents for the preparation of allogeneic hematopoietic progenitor cell (HPC) transplants for patients who have had prior stem cell transplants and require a stem cell "boost" from the original donor.
This protocol provides expanded access to bone marrow transplants for children who lack a histocompatible (tissue matched) stem cell or bone marrow donor when an alternative donor (unrelated donor or half-matched related donor) is available to donate. In this procedure, some of the blood forming cells (the stem cells) are collected from the blood of a partially human leukocyte antigen (HLA) matched (haploidentical) donor and are transplanted into the patient (the recipient) after administration of a "conditioning regimen". A conditioning regimen consists of chemotherapy and sometimes radiation to the entire body (total body irradiation, or TBI), which is meant to destroy the cancer cells and suppress the recipient's immune system to allow the transplanted cells to take (grow). A major problem after a transplant from an alternative donor is increased risk of Graft-versus-Host Disease (GVHD), which occurs when donor T cells (white blood cells that are involved with the body's immune response) attack other tissues or organs like the skin, liver and intestines of the transplant recipient. In this study, stem cells that are obtained from a partially-matched donor will be highly purified using the investigational CliniMACS® stem cell selection device in an effort to achieve specific T cell target values. The primary aim of the study is to help improve overall survival with haploidentical stem cell transplant in a high risk patient population by limiting the complication of GVHD.
The purpose of this study is to provide Decitabine to patients with Myelodysplastic syndrome (MDS) of all FAB (French-American-British) subtypes and Intermediate-1, Intermediate-2, and High-Risk International Prognostic Scoring System groups, including both previously treated and untreated patients.
RATIONALE: Giving low doses of chemotherapy and total-body irradiation before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer or abnormal cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer or abnormal cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus and mycophenolate mofetil before the transplant may stop this from happening. PURPOSE: This clinical trial is studying how well umbilical cord blood stem cell transplant works in treating patients with hematologic cancer or other disease.
