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

This phase II clinical trial studies how well treosulfan and fludarabine phosphate with or without low dose radiation before donor stem cell transplantation works in treating 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 are investigating whether a new conditioning regimen that uses less intensive drugs (treosulfan and fludarabine phosphate) with or without low dose radiation results in new blood-forming cells (engraftment) of the new donor cells without increased toxicities in patients with nonmalignant (noncancerous) diseases.

Study Overview

• Status: Completed
• Conditions: Non-Neoplastic Hematologic and Lymphocytic Disorder
• Intervention / Treatment: Other: Laboratory Biomarker Analysis; Drug: Methotrexate; Drug: Treosulfan; Biological: Anti-Thymocyte Globulin; Drug: Fludarabine Phosphate; Drug: Tacrolimus; Drug: Mycophenolate Mofetil; Drug: Cyclosporine; Radiation: Total-Body Irradiation; Procedure: Allogeneic Bone Marrow Transplantation; Procedure: Peripheral Blood Stem Cell Transplantation; Procedure: Umbilical Cord Blood Transplantation

Detailed Description

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 receive either bone marrow, peripheral blood stem cells (PBSC), or umbilical cord blood (UCB) 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 receive a combination of immunosuppressive medications to try and prevent graft-versus-host disease. There are 2 regimens depending on the donor.

Regimen A: Patients undergoing bone marrow or PBSC transplantation receive tacrolimus daily from day -1 to 50 followed by a taper until day 180 in the absence of GVHD. Patients also receive methotrexate IV on days 1, 3, 6, and 11.

Regimen B: Patients undergoing UCB transplantation receive cyclosporine on days -3 to 100 followed by a taper until day 180 in the absence of GVHD. Patients also receive mycophenolate mofetil on days 0 to 40 followed by a taper until day 96 in the absence of GVHD.

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

• Accepts Healthy Volunteers: No
• Genders Eligible for Study: All

Description

Inclusion Criteria:

• Patients with a nonmalignant disease treatable by allogeneic HCT
• Patients with a known nonmalignant disease that is not clearly defined will need to be discussed with the protocol principal investigator (PI) (Dr. Lauri Burroughs) and potentially the nonmalignant board to determine if they are eligible for HCT on this study
• DONOR: Human leukocyte antigens (HLA)-identical related donors or unrelated donors matched for HLA-A, B, C, DRB1, and DQB1 or mismatched for a single allele at HLA-A, B, C, DRB1 or a single DQB1 antigen or allele mismatch by high resolution deoxyribonucleic acid (DNA) typing
• DONOR: PBSC is the preferred cell source (when feasible) for fully matched donors; PBSC may also be used for a mismatched donor following discussion with the PI; bone marrow is allowed when PBSC is not feasible or as determined by the PI
• DONOR: HLA-matched sibling bone marrow in combination with HLA-matched sibling umbilical cord blood if the HLA-matched sibling umbilical cord blood was collected and stored; the HLA-matched sibling bone marrow and cord blood would be matched for HLA-A, B, C, DRB1, and DQB1
• DONOR: Unrelated Umbilical Cord Blood: Unit selection is based on the cryopreserved total nucleated cell (TNC) dose and matching at HLA-A, B antigen level and DRB1 allele level typing; while HLA-C antigen/allele level typing is not considered in the matching criteria, if available, may be used to optimize unit selection
• DONOR: Unrelated Umbilical Cord Blood: The patient and the cord blood unit(s) must be matched for at least 4 of 6 loci as defined above
• DONOR: Unrelated Umbilical Cord Blood: Selection of two umbilical cord blood (UCB) units is allowed to provide sufficient cell dose
• DONOR: Unrelated Umbilical Cord Blood: The UCB unit with the least HLA disparity (with the patient) will be selected first (i.e., selection priority is 6/6 match > 5/6 match> 4/6 match); additional UCB units then may be selected to achieve the required cell dose; if a second unit is required, this unit will be the unit that most closely HLA matches the patient and meets minimum size criteria outlined below of at least 1.5 x 10^7 TNC/kg (i.e. a smaller more closely matched unit will be selected over a larger less well matched unit as long as minimum criteria are met)
• DONOR: Unrelated Umbilical Cord Blood: Each UCB unit MUST contain at least 1.5 x 10^7 TNC per kilogram recipient weight
• DONOR: Unrelated Umbilical Cord Blood: The total cell dose of the combined units must be at least 3.0 x 10^7 TNC per kilogram recipient weight

Exclusion Criteria:

• Patients with idiopathic aplastic anemia and Fanconi anemia; (patients with aplastic anemia associated with paroxysmal nocturnal hemoglobinuria [PNH] or inherited marrow failure syndromes, except Fanconi anemia, will be allowed)
• Patients with impaired cardiac function as evidenced by ejection fraction < 35% (or, if unable to obtain ejection fraction, shortening fraction of < 26%) or cardiac insufficiency requiring treatment or symptomatic coronary artery disease; patients with a shortening fraction < 26% may be enrolled if approved by a cardiologist
• Patients with impaired pulmonary function as evidenced by diffusion capacity of the lung for carbon monoxide (DLCO) < 50% of predicted (or, if unable to perform pulmonary function tests, then oxygen [O2] saturation < 92% on room air)

• DONOR: Deemed unable to undergo marrow harvesting or PBSC mobilization and leukapheresis
• DONOR: HIV-positive
• DONOR: With active infectious hepatitis
• DONOR: Females with a positive pregnancy test
• DONOR: HLA-matched sibling cord blood exclusions: Any cord blood units that have not passed donor screening for infectious disease markers as recommended by the National Marrow Donor Project (NMDP) will not be used unless a waiver is signed by the clinical attending allowing use of cord blood unit; cord blood units are presumed to be cytomegalovirus (CMV) negative regardless of serologic testing due to passive transmission of maternal CMV antibodies
