Trial Outcomes & Findings for Maintenance Low Dose 5'-Azacitidine Post T Cell Depleted Allogeneic Stem Cell Transplantation for Patients With Myelodysplastic Syndrome and Acute Myelogenous Leukemia With High Risk for Post-Transplant Relapse (NCT NCT01995578)

NCT ID: NCT01995578

Last Updated: 2024-05-22

Results Overview

Relapse of MDS or AML will be analyzed as to type and genetic origin of the leukemic cells. These will be defined by morphologic and/or cytogenetic criteria: an increasing number of blasts in the marrow over 5%, by presence of circulating blasts, or by presence of blasts in any extramedullary site as well as presence of previous cytogenetic abnormalities. Other studies assessing for MRD, FACS and FISH assays will be evaluated but would not be considered disease relapse if positive since they are experimental.
