Clinical Trial Summary

Allogeneic hematopoietic cell transplantation (allo-HCT) is a potentially curative therapy for patients with hematologic malignancies including acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and acute lymphoblastic leukemia (ALL); however, human leukocyte antigen (HLA)-matched donor availability continues to be a major hurdle. Historically, HLA haploidentical donor hematopoietic cell transplantation (haplo-HCT) was associated with high incidences of graft rejection and excessive non-relapse mortality (NRM), but recent advances utilizing post-transplant cyclophosphamide (PT-Cy) have revolutionized haplo-HCT and the outcomes are now comparable to allo-HCT using more traditional HLA matched related and unrelated donors. However, graft-versus-host disease (GvHD) continues to be a problem and is associated with significant morbidity and mortality in allo-HCT patients including those who receive haplo-HCT on PT-Cy platform. The aim of this early phase study is to investigate the safety and overall efficacy of azacitidine in reducing the incidence and severity of GvHD when added to PT-Cy based haplo-HCT platform for patients with AML, ALL, or advanced MDS.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Safety of azacitidine (Phase I only) as measured by frequency and grade of adverse events	The descriptions and grading scales found in the revised NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 will be utilized for all toxicity reporting.	Up to Day 35
Primary	Maximum tolerated dose of azacitidine (Phase I only)		Estimated to be 3-4 months (completion of all Phase I patients through Day 35)
Primary	Grade II-IV acute GvHD rate of azacitidine (Phase II only)		Up to Day 100
Secondary	Event-free survival (EFS)	EFS is defined as the time from date of first dose of the preparative regimen until failure to engraft, treatment failure, disease progression/relapse, or death from any cause (whichever occurs first).	Up to 48 months
Secondary	Overall survival (OS)	OS is defined as the time from the date of Day 0 until death from any cause.	Up to 48 months
Secondary	Disease-free survival (DFS)		Up to 48 months
Secondary	Non-relapse mortality (NRM)	NRM is defined as death that results from a transplant procedure-related complication (e.g. infection, organ failure, hemorrhage, GvHD) rather than from relapse of the underlying disease prior to Day +100 visit.	Up to Day 100
Secondary	Time to neutrophil engraftment	Time to neutrophil engraftment is measured by determining the first of 3 consecutive measurements of neutrophil count = 500/ul following conditioning regimen-induced nadir.	Up to 12 months
Secondary	Time to platelet engraftment	Time to platelet engraftment is measured by determining the first of 3 consecutive measurements of platelet count = 20,000/ul without platelet transfusion support for 7 days.	Up to 12 months
Secondary	Rate of acute GvHD	Incidence and severity of acute GvHD will be assessed based on the modified Glucksberg criteria and Seattle criteria. Attempts should be made to confirm the diagnosis pathologically by biopsy of target organ(s).	Up to Day 100
Secondary	Rate of chronic GvHD	Incidence and severity of chronic GvHD will be assessed based on the NIH consensus criteria and global severity scoring system. Attempts should be made to confirm the diagnosis pathologically by biopsy of target organ(s).	Day 100 through Day 365
