Description
Summary
1703: The study is designed as a randomized, phase III, multicenter trial comparing two acute graft-versus-host disease (aGVHD) prophylaxis regimens: tacrolimus/methotrexate (Tac/MTX) versus post-transplant cyclophosphamide/tacrolimus/mycophenolate mofetil (PTCy/Tac/MMF) in the setting of reduced intensity conditioning (RIC) allogeneic peripheral blood stem cell (PBSC) transplantation.
1801: The goal of this protocol is to test the primary hypothesis that the engraftment stool microbiome diversity predicts one-year non-relapse mortality in patients undergoing reduced intensity allogeneic HCT.
Official Title
A Randomized, Multicenter, Phase III Trial of Tacrolimus/Methotrexate Versus Post-Transplant Cyclophosphamide/Tacrolimus/Mycophenolate Mofetil in Non-Myeloablative/Reduced Intensity Conditioning Allogeneic Peripheral Blood Stem Cell Transplantation (BMT CTN 1703; Progress III); Companion Study: Microbiome and Immune Reconstitution in Cellular Therapies and Hematopoietic Stem Cell Transplantation (BMT CTN 1801; Mi-Immune)
Details
1703: Graft-versus-Host Disease (GVHD) is a complication that affects many hematopoietic stem cell transplant (HSCT) patients; it occurs when the new cells from a transplant attack the recipient's body. The current standard GVHD prophylaxis regimen for patients with hematologic malignancies undergoing HSCT involves a combination of immunosuppressive agents given for the first 6 months after transplant.
The standard strategy of Tacrolimus/Methotrexate will be used as a control arm in comparison to one other treatment plan utilizing Tacrolimus/Mycophenolate Mofetil/Post-Transplant Cyclophosphamide. Study participants will receive an infusion of mobilized peripheral blood stem cell grafts on both arms. Study participants will be randomized to one of these two treatment arms.
1801: A relationship between the intestinal microbiota and graft-versus-host disease (GVHD) has long been appreciated but is still not well understood. Mice transplanted in germ-free conditions or treated with gut-decontaminating antibiotics developed less severe GVHD. Clinical studies initially suggested a benefit from near-total bacterial decontamination, but later showed no clear benefit and this approach was discontinued in the early 1990s. Partial gut decontamination continues to be practiced at many centers. More recently, the advent of next-generation sequencing (NGS) has resulted in cheaper and easier characterization of complex microbial mixtures. This has led to a renewed interest in evaluating the relationship between the microbiota and human health and disease, including recipients of hematopoietic cell transplantation (HCT). Similarly, NGS has also contributed to significant advancements in the investigator's understanding of immune reconstitution in HCT patients and how this may impact clinica outcomes.
The goal of this protocol is to test the primary hypothesis that the engraftment stool microbiome diversity predicts one-year non-relapse mortality in patients undergoing reduced intensity allogeneic HCT.

Eligibility
You can join if…
Open to people ages 18 years and up
- Age 18.0 years or older at the time of enrollment on Segment A
- Patients with acute leukemia or chronic myelogenous leukemia with no circulating blasts and with less than 5% blasts in the bone marrow
- Patients with myelodysplasia/chronic myelomonocytic leukemia with no circulating blasts and with less than 10% blasts in the bone marrow (higher blast percentage allowed in MDS due to lack of differences in outcomes with <5% vs. 5-10% blasts in this disease)
- Patients with relapsed chronic lymphocytic leukemia/small lymphocytic lymphoma with chemosensitive disease at time of transplantation
- Patients with lymphoma [follicular lymphoma, Hodgkin lymphoma, diffuse large B cell lymphoma, mantle cell lymphoma, peripheral T-cell lymphoma, angioimmunoblastic T-cell lymphoma and anaplastic large cell lymphoma] with chemosensitive disease at the time of transplantation
- Planned reduced intensity conditioning regimen (see eligible regimens in Table 2.4a)
- Patients must have a related or unrelated peripheral blood stem cell donor as follows:
- Sibling donor must be a 6/6 match for Human Leukocyte Antigen-A (HLA)-A and -B at intermediate (or higher) resolution, and -DRB1 at high resolution using DNA-based typing, and must be willing to donate peripheral blood stem cells and meet institutional criteria for donation.
- Unrelated donor must be a 7/8 or 8/8 match at HLA-A, -B, -C and -DRB1 at high resolution using DNA-based typing. Unrelated donor must be willing to donate peripheral blood stem cells and meet National Marrow Donor Program (NMDP) criteria for donation.
- Cardiac function: Left ventricular ejection fraction at least 45%
Estimated creatinine clearance acceptable per institutional guidelines
10. Pulmonary function: Diffusing capacity of lung for carbon monoxide (DLCO) corrected
for hemoglobin at least 40% and forced expiratory volume at one second (FEV1) predicted at least 50%
11. Liver function acceptable per institutional guidelines 12. Karnofsky Performance Score at least 60% 13. Female patients (unless postmenopausal for at least 1 year before the screening visit,
or surgically sterilized), agree to practice two (2) effective methods of contraception at the same time, or agree to completely abstain from heterosexual intercourse, from the time of signing the informed consent through 12 months post-transplant (see Section 2.6.4 for definition of postmenopausal)
14. Male patients (even if surgically sterilized), of partners of women of childbearing
potential must agree to one of the following: practice effective barrier contraception (see Section 2.6.4 for list of barrier methods), or abstain from heterosexual intercourse from the time of signing the informed consent through 12 months post-transplant
15. Plans for the use of post-transplant maintenance therapy must be disclosed upon
enrollment and must be used irrespective of the outcome of the randomization. Please note that THIS DOES NOT INCLUDE INVESTIGATIONAL AGENTS and maintenance therapy with investigational treatment requires approval by the study chairs.
16. Voluntary written consent obtained prior to the performance of any study-related
procedure that is not a part of standard medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care.
