MT2016-15 :Reduced Intensity (RIC) Conditioning And Transplantation of HLA-Haploidentical Related Hematopoietic Cells (Haplo-HCT) For Patients With Hematologic Malignancies


This is a two stage phase II trial of HLA-haploidentical related hematopoietic cells transplant (Haplo-HCT) using a reduced intensity conditioning (cyclophosphamide, fludarabine, melphalan, total body irradiation) with modifications based on factors including age and comorbidities. Bone marrow is the donor graft source. This study is designed to estimate disease-free survival (DFS) at 1 year posttransplant. Since the goal is to estimate the DFS at a long-term time-point (1 year post-transplant), the design is a generalization of the Simon design. Rather than suspension of the trial for evaluation after stage 1, this design uses an optimal interim analysis for futility without suspension of accrual.

This study is NOT accepting healthy volunteers
Inclusion Criteria:

• Karnofsky performance status of ≥70% or Lansky play score ≥ 70%
• A related haploidentical bone marrow donor with up to 2 or 3 HLA locus-mismatches
• The donor and recipient must be HLA identical for at least one haplotype (using high resolution DNA based typing) at the following genetic loci: HLA-A, HLA-B, HLA-C, and HLA-DRB1.
• Adequate liver and renal function
• Absence of decompensated congestive heart failure, or uncontrolled arrhythmia and left ventricular ejection fraction ≥ 40%
• Diffusion capacity corrected (DLCOcorr) > 40% predicted, and absence of O2 requirements
• > 6 months after prior autologous transplant (if applicable)
• Agrees to use contraception during study treatment
• Voluntary written consent (adult or parent/guardian with presentation of the minor information sheet, if appropriate)
• Patients who are HIV+ must have undetectable viral load. All HIV+ patients must be evaluated by Infectious Disease (ID) and a HIV management plan establish prior to transplantation
Exclusion Criteria:

• < 70 years with an available 5-6/6 HLA-A, B, DRB1 matched sibling donor
• Pregnancy or breastfeeding
• Current active and uncontrolled serious infection
• Acute leukemia in morphologic relapse/persistent disease defined as > 5% blasts in normocellular bone marrow OR any % blasts if blasts have unique morphologic markers (e.g. Auer rods).
• CML in blast crisis
• Large cell lymphoma, mantle cell lymphoma and Hodgkin disease that is progressive on salvage therapy.
• stable non-bulky disease is acceptable.
• Active central nervous system malignancy Criteria For Donor Selection:
• Donors must be HLA-haploidentical relatives of the patient, defined as having a shared HLA haplotype between donor and patient at HLA-A, -B, -C, and -DRB1.
• Eligible donors (14-70 years old) include biological children, siblings or half siblings, or parents, able and willing to undergo bone marrow harvesting.
• For donors <18 years, the maximum recipient weight (actual body weight) should not exceed 1.25 times the donor weight (actual body weight)1 In addition, bone marrow product volume should be limited to 20 ml/kg donor weight for donors <18 years.
