Novel Approaches for Graft-versus-Host Disease Prevention Compared to Contemporary Controls (BMT CTN 1203)

Inclusion Criteria:

1. Age 18-75 years (patient is older than 18.0 and less than 76.0 years old)
2. Patients with acute leukemia, chronic myelogenous leukemia or myelodysplasia with no circulating blasts and with less than 5% blasts in the bone marrow.
3. Patients with chronic lymphocytic leukemia/small lymphocytic lymphoma, follicular, marginal zone, diffuse large B-cell, Hodgkin's Lymphoma,or mantle cell lymphoma with chemosensitive disease at time of transplantation
4. Planned reduced intensity conditioning regimen (see eligible regimens in Table 2.4a)
5. Patients must have a related or unrelated peripheral blood stem cell donor as follows:

   1. Sibling donor must be a 6/6 match for 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.
   2. 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 be medically cleared to donate stem cells according to National Marrow Donor Program (NMDP) criteria.
6. Cardiac function: Ejection fraction at rest ≥ 45%
7. Estimated creatinine clearance greater than 50 mL/minute (using the Cockcroft-Gault formula and actual body weight)
8. Pulmonary function: Diffusing capacity of the lung for carbon monoxide (DLCO) ≥ 40% (adjusted for hemoglobin) and forced expiratory volume in one second (FEV1) ≥ 50%
9. Liver function: total bilirubin \< 1.5 x the upper limit of normal and alanine aminotransferase (ALT)/aspartate aminotransferase (AST) \< 2.5x the upper normal limit. Patients who have been diagnosed with Gilbert's Disease are allowed to exceed the defined bilirubin value of 1.5x the upper limit of normal.
10. Female subjects (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).
11. Male subjects (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.
12. Signed informed consent

Exclusion Criteria:

1. Prior allogeneic transplant
2. Karnofsky Performance Score \< 70%
3. Active central nervous system (CNS) involvement by malignant cells
4. Patients with uncontrolled bacterial, viral or fungal infections (currently taking medication and with progression or no clinical improvement) at time of enrollment.
5. Presence of fluid collection (ascites, pleural or pericardial effusion) that interferes with methotrexate clearance or makes methotrexate use contraindicated
6. Patients with transformed lymphoma (e.g., Richters transformation arising in follicular lymphoma or chronic lymphocytic leukemia)
7. Patients seropositive for the human immunodeficiency virus (HIV)
8. Patient with active Hepatitis B or C determined by serology and/or nucleic acid amplification tests (NAAT)
9. Patients with hypersensitivity to bortezomib, boron or mannitol
10. Patients with ≥ grade 2 sensory peripheral neuropathy
11. Myocardial infarction within 6 months prior to enrollment or New York Heart Association (NYHA) Class III or IV heart failure (see Appendix D), uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities. Prior to study entry, any ECG abnormality at screening must be documented by the investigator as not medically relevant.
12. Female patients who are lactating or pregnant
13. Patients with a serious medical or psychiatric illness likely to interfere with participation in this clinical study
14. Patients with prior malignancies except resected basal cell carcinoma or treated cervical carcinoma in situ. Cancer treated with curative intent ≥ 5 years previously will be allowed. Cancer treated with curative intent \< 5 years previously will not be allowed unless approved by the Protocol Officer or one of the Protocol Chairs.
15. Planned use of anti-thymocyte globulin (ATG) or alemtuzumab in conditioning regimen.
16. Planned post-transplant therapy, including use of tyrosine-kinase inhibitors (TKI).
17. Inability to withhold agents that may interact with hepatic cytochrome P450 enzymes (CYP3A4), or glutathione S-transferases involved in bortezomib and/or busulfan metabolism during day -5 through day +7. It is acceptable to use alternative non-interacting medications during this period, and then resume prior medications.
18. Patients with secondary acute myeloid leukemia arising from myeloproliferative disease, including Chronic myelomonocytic leukemia (CMML), with evidence of active myeloproliferative features or myelofibrosis in the background.
