Brief Title: Treosulfan-Based Conditioning Regimen Before a Blood or Bone Marrow Transplant for the Treatment of Bone Marrow Failure Diseases (BMT CTN 1904)
Official Title: Hematopoietic Cell Transplantation Using Treosulfan-Based Conditioning for the Treatment of Bone Marrow Failure Diseases
Study ID: NCT04965597
Brief Summary: This phase II trial tests whether treosulfan, fludarabine, and rabbit antithymocyte globulin (rATG) work when given before a blood or bone marrow transplant (conditioning regimen) to cause fewer complications for patients with bone marrow failure diseases. Chemotherapy drugs, such as treosulfan, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Fludarabine may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. rATG is used to decrease the body's immune response and may improve bone marrow function and increase blood cell counts. Adding treosulfan to a conditioning regimen with fludarabine and rATG may result in patients having less severe complications after a blood or bone marrow transplant.
Detailed Description: OUTLINE: CONDITIONING REGIMEN: Patients receive treosulfan intravenously (IV) over 120 minutes on days -6 to -4, fludarabine phosphate IV over 60 minutes on days -6 to -2, and lapine T-lymphocyte immune globulin (rATG) IV over 4-6 hours on days -4 to -2. TRANSPLANTATION: Patients undergo bone marrow or peripheral blood stem cell transplant on day 0. GVHD PROPHYLAXIS: Patients receive tacrolimus IV continuously beginning on day -2 and a taper beginning on day 180. Patients may also receive tacrolimus orally (PO). Patients also receive methotrexate IV on days 1, 3, 6, and 11. Patients undergo echocardiography (ECHO) or multigated acquisition scan (MUGA) during screening and undergo bone marrow biopsy and aspiration at baseline and follow up. Patients may optionally undergo blood sample collection throughout the trial. After completion of study treatment, patients are followed up at 1 year from transplant.
