Clinical Trial Summary

Allogeneic stem cell transplantation followed by targeted immune therapy with Gemtuzumab Ozogamicin (Mylotarg) will be given to patients with average risk AML or MDS.

Description:

Reduced intensity conditioning regimen of Busulfan (Bu) and Fludarabine (Flu) + Anti-Thymocyte Globulin (ATG ) (unrelated donors only) or reduced toxicity conditioning regimen of Bu/Flu/alemtuzumab, or reduced hepatic toxicity regimen of melphan/Flu/alemtuzumab and AlloSCT, followed by Gemtuzumab Ozogamicin consolidation in patients with average risk AML/MDS meeting eligibility criteria.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	to evaluate incidence of graft failure	If three or more of the first ten patients experience primary or secondary graft failure, we will discontinue the study.	Day +42
Primary	to evaluate survival rates	Event-free survival and overall survival after RI AlloSCT and targeted immunotherapy in patients with average risk AML/MDS.	1 year
Primary	to determine toxicity	to monitor for serious adverse events related to protocol investigational therapy	1 year
Secondary	Minor histocompatibility antigen	To measure the minor histocompatibility antigen expression on AML tissue, donor and recipient, and the development of MHA specific CTLs post AlloSCT.	1 year
Secondary	Chimerism	To determine the degree of mixed/complete donor chimerism after RI AlloSCT in patients with average risk AML/MDS.	1 year
Secondary	Graft-versus-host disease	To estimate the risk of acute and chronic GVHD following RI AlloSCT and FK506/MMF GVHD prophylaxis in patients with average risk AML/MDS.	1 Year
