Complete title: Allogeneic Hematopoietic Cell Transplantation for Patients with Nonmalignant Inherited Disorders Using a Treosulfan Based Preparative Regimen
|Research Study Number||2256.00|
|Principal Investigator||Lauri Burroughs, MD|
Sexes Eligible for Study: All
- 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 (ie 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
Other eligibility criteria may apply.
- 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)
- Patients with impaired renal function as evidenced by creatinine-clearance < 50% for age, weight, height or serum creatinine > 2 x upper normal limit or dialysis-dependent
- Patients with evidence of synthetic dysfunction or severe cirrhosis requiring deferral of conditioning as recommended by a gastroenterology specialist
- Patients with an active infectious disease requiring deferral of conditioning; as recommended by an infectious disease specialist
- Patients who are positive for human immunodeficiency virus (HIV)
- Females who are pregnant or breast-feeding
- Patients with a known hypersensitivity to treosulfan and/or fludarabine
- Receiving another experimental drug within 4 weeks of initiation of conditioning (day -6) unless approved by the PI
- 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 without full maternal testing and negative results for hepatitis A, B, C, HIV, and HTLV-1 viruses; any additional available virology results on the unit itself will be reviewed but are not mandated, complete or always available; cord blood units are presumed to be cytomegalovirus (CMV) negative regardless of serologic testing due to passive transmission of maternal CMV antibodies
- DONOR: Unrelated Umbilical Cord Blood: Any cord blood units with < 1.5 x 10^7 total nucleated cells per kilogram recipient weight
- DONOR: Unrelated Umbilical Cord Blood: Any cord blood units without full maternal testing and negative results for hepatitis A, B, C, HIV, and HTLV-1 viruses; any additional available virology results on the unit itself will be reviewed but are not mandated, complete or always available; cord blood units are presumed to be CMV negative regardless of serologic testing due to passive transmission of maternal CMV antibodies
Other exclusion criteria may apply.
