About
This clinical trial studies intra-osseous donor umbilical cord blood and mesenchymal stromal cell co-transplant in treating patients with hematologic malignancies. Giving low doses of chemotherapy and total-body irradiation before a co-transplant of donor umbilical cord blood and mesenchymal stromal cells into the bone (intra-osseous) helps stop the growth of cancer cells. It may also stop 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 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 cyclosporine and mycophenolate mofetil at the time of transplant may stop this from happening.
Full description
PRIMARY OBJECTIVES:
I. To estimate the feasibility of combining intra-osseous umbilical cord blood (UCB) hematopoietic stem cells and human mesenchymal stromal cells (hMSC) following reduced intensity conditioning (RIC).
SECONDARY OBJECTIVES:
I. To estimate the time to engraftment of intra-osseous (IO) UCB transplant combined with hMSC following RIC.
II. To estimate the safety profile of IO UBC transplant combined with hMSC.
OUTLINE:
REDUCED INTENSITY CONDITIONING: Patients receive cyclophosphamide intravenously (IV) over 2 hours on day -6 and fludarabine phosphate IV on days -6 to -2 and undergo total body irradiation (TBI) on day -1.
GRAFT-VERSUS-HOST DISEASE (GVHD) PROPHYLAXIS: Patients receive cyclosporine orally (PO) or IV over 2 hours every 12 hours on beginning on days -5 to 100 with taper beginning on day 100 and mycophenolate mofetil IV or PO twice daily (BID) on days -5 to 100.
TRANSPLANT: Patients undergo intra-osseous UCB and hMSC co-transplant on day 0.
After completion of study treatment, patients are followed up at days 28 and 100, and then at 6, 9, and 12 months.

Inclusion criteria
Patients must have one of the following malignancies:
Acute myelogenous leukemia (AML): high-risk AML including:
Antecedent hematological disease (e.g., myelodysplasia [MDS])
Treatment-related leukemia
Complete remission (first complete remission [CR1]) with poor-risk cytogenetics or molecular markers (e.g. fms-related tyrosine kinase 3 [Flt 3] mutation, 11q23, del 5, del 7, complex cytogenetics)
Second complete remission (CR2) or third complete remission (CR3)
Induction failure or first relapse with either
Acute lymphoblastic leukemia (ALL)
High-risk CR1 including:
Poor-risk cytogenetics (e.g., Philadelphia chromosome t(9;22)or 11q23 rearrangements)
Presence of minimal disease by flow cytometry after 2 or more cycles of chemotherapy
No complete remission (CR) within 4 weeks of initial treatment
Induction failure
CR2 or CR3 with either:
Myelodysplastic syndromes (MDS), Intermediate-1 (INT-1), intermediate-2 (INT-2) or high Revised International Prognostic Scoring System (IPSS-R) score that has failed at least 1 first line therapy
Myelofibrosis (MF):
Relapsed or refractory lymphoid malignancies (including non-Hodgkin lymphoma, Hodgkin lymphoma and chronic lymphocytic leukemia) meeting the following criteria:
Chronic myelogenous leukemia (CML) in second chronic phase after accelerated or blast crisis; blast crisis defined as:
Recipients of prior autologous or allogeneic transplant are eligible, as long as at least 3 months have passed since the transplant, and the patient fulfills other eligibility criteria
Eastern Cooperative Oncology Group (ECOG) performance status ≤2
Candidates for reduced intensity conditioning regimens
Patients who do not have HLA-matched (defined as matched in HLA A, B, C, and DRB1) related or unrelated donors, those who elect to undergo UCB even if they have a MRD or MUD, or patients who require a UCB either for emergency indications such as primary graft failure.
Cord Blood Units available through NMDP with the following minimal criteria:
Concurrent therapy for extramedullary leukemia or central nervous system (CNS) lymphoma: concurrent therapy or prophylaxis for testicular leukemia, CNS leukemia, and CNS lymphoma including standard intrathecal chemotherapy and/or radiation therapy will be allowed as clinically indicated; such treatment may continue until the planned course is completed; subjects must be in CNS remission at the time of protocol enrollment if there is a history of CNS involvement
Subjects must have a back-up umbilical cord on the registry in addition to the umbilical cord being used in this study
Subjects must have the ability to understand and the willingness to sign a written informed consent document
Exclusion criteria
Patients with inadequate Organ Function as defined by:
Left ventricular ejection fraction < 35%
Patients with uncontrolled inter-current illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
Pregnant or breastfeeding women are excluded from this study
