Treosulfan and Fludarabine Phosphate Before Donor Stem Cell Transplant in Treating Patients With Nonmalignant Inherited Disorders
Allogeneic Hematopoietic Cell Transplantation for Patients With Nonmalignant Inherited Disorders Using a Treosulfan Based Preparative Regimen.

The purpose of this phase II clinical trial is to see if the combination of two chemotherapy drugs, treosulfan and fludarabine phosphate with or without low dose radiation, just prior to stem cell transplantation is safe and effective in patients with nonmalignant (noncancerous) diseases. Hematopoietic cell transplantation has been shown to be curative for many patients with nonmalignant (noncancerous) diseases such as primary immunodeficiency disorders, bone marrow failure syndromes, hemoglobinopathies, and inborn errors of metabolism (metabolic disorders). Powerful chemotherapy drugs and/or radiation are often used to condition the patient before infusion of the new healthy donor cells. The purpose of the conditioning therapy is to destroy the patient's abnormal bone marrow which doesn't work properly in order to make way for the new healthy donor cells which functions normally. Although effective in curing the patient's disease, many hematopoietic cell transplantation regimens use intensive chemotherapy and/or radiation which can be quite toxic, have significant side effects, and can potentially be life-threatening. Investigators at the Fred Hutchinson Cancer Research Center in collaboration with Oregon Health & Sciences University, Vanderbilt University, and Medical College of Wisconsin are investigating whether a new conditioning regimen that uses less intensive drugs (treosulfan and fludarabine phosphate) with or without low dose radiation results in engraftment of the new donor cells without increased toxicities in patients with nonmalignant (noncancerous) diseases.

PRIMARY OBJECTIVES:

I. To evaluate, within the limits of a phase II study, the preliminary efficacy, as defined by engraftment, of a regimen consisting of treosulfan and fludarabine (fludarabine phosphate) followed by allogeneic hematopoietic cell transplantation (HCT) in patients with nonmalignant inherited disorders.

SECONDARY OBJECTIVES:

I. To evaluate the incidence of non-relapse mortality 200 days and 1 year post-HCT.

II. To evaluate the incidence of grade II-IV acute graft-versus-host disease (GVHD).

III. To evaluate the incidence of chronic GVHD as defined as those patients requiring systemic immunosuppression.

IV. To evaluate donor chimerism on days +28 and +100.

V. To assess disease response following HCT.

VI. To evaluate immune reconstitution following HCT.

VII. To evaluate the incidence of infections.

VIII. To evaluate overall survival.

OUTLINE:

CONDITIONING REGIMEN: Patients receive treosulfan intravenously (IV) over 2 hours on days -6 to -4 and fludarabine phosphate IV over 1 hour on days -6 to -2. Patients receive anti-thymocyte globulin IV over 4-6 hours on days -4 to -2. Patients undergoing umbilical cord blood transplantation will also receive low dose total-body irradiation on day -1.

TRANSPLANTATION: Patients will receive either bone marrow, peripheral blood stem cells (PBSC), or umbilical cord blood from the donor on day 0. The use of either bone marrow, PBSC, or umbilical cord blood will depend on the donor status.

IMMUNOSUPPRESSION: Patients will receive a combination of immunosuppressive medications to try and prevent graft-versus-host disease. If patients undergo bone marrow or PBSC transplantation, tacrolimus and methotrexate will be used. If patients undergo cord blood transplantation, cyclosporine and mycophenolate mofetil will be used. In general, patients will receive immunosuppression until at least 180 days after transplantation; however they could be on immunosuppression longer if they develop graft versus host disease.

After completion of study treatment, patients are followed up periodically for 5 years.
