This is a prospective, single-arm, phase II study. Patients will be treated with an allogeneic stem cell transplantation (AHSCT) using fludarabine, melphalan and total body irradiation (TBI) conditioning with different melphalan and TBI doses based on patient- and disease-related risk.

Official Title

Risk-ADAPTed Conditioning Regimen for Allogeneic Hematopoietic Stem Cell Transplantation (ADAPT)


Eligible patients will receive an allogeneic stem cell transplantation using a combination of fludarabine, melphalan and total body irradiation (TBI) conditioning regimen and post-transplant high dose cyclophosphamide (PTCY), tacrolimus and mycophenolate mofetil (MMF) for graft-versus-host prophylaxis.

Melphalan and TBI doses will be tailored based on the Hematopoietic Stem Cell Transplant- Composite Risk (HCT-CR), age and Karnofski performance status (KPS). Melphalan dose ranges from 100 -140 mg/m2 while TBI dose ranges from 2-5 Gy.

All patients will be monitored for safety and efficacy up to 2 years post-transplantation.
