Interventions
Patients receiving reduced dose of PTCy at 35mg.kg on day +3 and +4 together with tacrolimus starting from day+5 and single dose of anti-thymoglobin (ATG) 2.5mg/kg at 72 hours after documentation of neutrophil engraftment.
Patients receiving standard dose PTCy at 50mg/kg on day +3 and +4 with tacrolimus starting from day +5 and single dose of anti-thymoglobin at 2.5mg/kg 72 hours after documentation of neutrophil engraftment.
