Clinical Trial Summary

The purpose of this study is to determine whether 5-Azacytidine priming before the conditioning regimen for subjects receiving a hematopoietic stem cell transplant is an effective treatment for high risk myeloid malignancies in complete remission (CR).


Description:

This open label two-step phase II study is designed to determine the safety and efficacy of epigenetic priming with 5-Azacytidine immediately prior to reduced intensity conditioning for an in vivo T-cell depleted hematopoietic stem cell transplantation for high risk myeloid malignancies in complete remission (CR). Subjects will be given a five day course of subcutaneous 5-azacytidine, followed by a reduced intensity conditioning regimen of fludarabine, melphalan and total body irradiation (TBI) prior to an allogeneic hematopoietic stem cell transplantation from a related or unrelated Human Leukocyte Antigen (HLA) matched donor. The effect of 5-azacytidine on global gene methylation will be assessed. Evaluations for safety, in particular for graft failure, transplant related mortality and acute graft versus host disease will be made on a weekly basis. Efficacy, as defined by disease free survival, will be evaluated with a bone marrow biopsy at the standard time points, which are one-, three-, six-, and twelve-months after transplant and upon clinical suspicion within regular follow-up visits - weekly for the first 3 months, then biweekly for 3 months, then monthly until one-year post-stem cell transplant. Thereafter, unless otherwise dictated by the clinical scenario, the follow up visits will be every 3 months.

Eligibility Inclusion Criteria: - Patients must have histologically or cytologically confirmed acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) as specified below: 1. Acute myeloid leukemia with poor risk cytogenetics in complete morphologic remission. These include: del (5q)/-5, del (7q)/-7, abn 3q, 9q, 11q, 20q, 21q, 17p, t(6;9), t(9;22) or complex karyotypes (= 3 unrelated abnormalities); or 2. Acute myeloid leukemia with either Flt-3, TET-2, p53, DNMT3A, or ASXL1 mutation, mutations of genes involved in the chromatin/spliceosome category (EZH2, SRSF2, U2AF1, ZRSR2), BCOR, and RUNX1, as well as MLL rearrangement, EVI1 overexpression in complete morphologic remission; or 3. Acute myeloid leukemia with a white blood cell count of greater than or equal to 50,000/mcL at presentation in first complete morphologic remission; or 4. Acute myeloid leukemia in first complete morphologic remission, having required more than one course of induction chemotherapy to attain remission status; or 5. Acute myeloid leukemia, all types, excluding M3 (Promyelocytic leukemia) in second or higher complete morphologic remission; or 6. Myelodysplastic syndromes (intermediate-2, high risk and chronic myelomonocytic leukemia (CMML) with bone marrow blasts <5%); or 7. Secondary acute myeloid leukemia on the basis of prior MDS or prior myeloproliferative neoplasm (MPN) in complete morphologic remission - Life expectancy not severely limited by concomitant disease - Karnofsky Performance Score greater than or equal to 70%. - Adequate organ function as defined below: Serum Bilirubin:<2.0 mg/dL; Alanine Aminotransferase (ALT) (SGPT): <3 x upper limit of normal; Creatinine Clearance:>60 mL/min (eGFR as estimated by the modified Modification of Diet in Renal Disease Study (MDRD) equation) - Ability to understand and the willingness to sign a written informed consent document. Exclusion Criteria: - Evidence of chronic active hepatitis or cirrhosis - HIV infection - Uncontrolled 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 and lactating women are excluded from the study because the risks to an unborn fetus or potential risks in nursing infants are unknown. - There are no prior therapies or concomitant medications that would render the patients ineligible

Study Design


Intervention

Drug:
5-Azacytidine
Patients will be given a five day course of subcutaneous 5-azacytidine followed by a reduced intensity conditioning regimen of fludarabine and melphalan with or without total body irradiation prior to an allogeneic hematopoietic stem cell transplantation from a related or unrelated HLA matched donor. 5-Azacytidine 75 mg/m2 subcutaneously daily at the same time on days -11, -10, -9, -8 and -7. This will be administered on an outpatient basis if possible.
Fludarabine
Conditioning regimen: Hospital admission will usually take place on the first day of the conditioning regimen. Fludarabine will be given at 40 mg/m2 intravenously daily at the same time over 30 minutes on days -6,-5,-4,-3.
Melphalan
Conditioning regimen: Hospital admission will usually take place on the first day of the conditioning regimen. Melphalan will be given at 140 mg/m2 IV on day -3.
Alemtuzumab
Conditioning regimen: Hospital admission will usually take place on the first day of the conditioning regimen. Alemtuzumab will be given at 30 mg subcutaneously on Days -4 and -2 for unrelated donors, and Day -2 for related donors.
Radiation:
Total Body Irradiation
Conditioning regimen: Hospital admission will usually take place on the first day of the conditioning regimen. Total Body Irradiation (TBI) will be given at 2 doses of 200 cGy each on one day of the conditioning regimen (between days -6 and -3).
